Abstract

PURPOSE:To effectively increase the bending rigidity of a column body without much increasing whole weight by providing a truss member to connect a main material to the column body on the base table of an article delivering/receiving body along the moving direction of the article delivering/receiving body. CONSTITUTION:In the case where an article delivering/receiving body 100 is increased or decreased in its moving speed, force which deflects an upper part taking the lower end of the body 100 as a basic point in the moving direction of the body 100 acts on a column body 70, which is therefore provided with a truss member 180, and composed of an oblique material 182 which obliquely connects a main material 181 to connect the upper end of the column body 70 with the end in a moving direction of a base table 60 with the column body 70 and a horizontal material 183 to horizontally connect them for effectively heightening the bending rigidity of the column body 70 in the moving direction of the body 100, and the deflection caused by the said force of the column body 70 can therefore be controlled. Thus, a state where the column body 70 oscillates at the time of stopping the body 100 can be prevented, and the delivery and receipt of an article 20 through the body 100 can be smoothly and surely carried out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a plurality of storage shelves arranged vertically and horizontally in a storage rack installed in a warehouse.
The present invention relates to an automated warehouse configured so that articles can be automatically taken in and out.

[0002]

2. Description of the Related Art Automatic warehouses of this type are known, for example, from 2-52
As described in Japanese Patent No. 804, the storage rack is provided with an article depositing / dispensing body for loading and unloading articles from a plurality of storage shelves arranged vertically and horizontally. Generally, such an article dispenser includes a base that is movable in the left-right direction along a storage rack, a vertically extending column whose bottom end is fixed to the base, and a vertical direction that extends along the column. And a loading / unloading body provided on the lifting / lowering body for loading and unloading articles from / into the storage rack, and moved in the left-right direction along the storage rack as a whole by the driving force applied to the base. It is like this.

[0003]

By the way, when the bending rigidity of the column in the moving direction of the base is low, the column is bent by the force acting on the column when the base is accelerated or decelerated, and the base is stopped. The pillars sometimes shake. Especially when the pillar is long in the vertical direction, such shaking of the pillar is likely to occur. If the pillar is swaying when the base is stopped, it becomes difficult to smoothly and reliably take articles in and out of the storage rack.

On the other hand, in order to improve the bending rigidity of the columnar body, if the cross-sectional area of the members constituting the columnar body is increased and the weight of the columnar body is greatly increased, the weight of the entire article delivery / dispensing body is increased. This leads to an increase in the number of items, which hinders the smooth movement of the article depositing and dispensing body.

The present invention has been made in view of the above circumstances, and an object thereof is to effectively increase the bending rigidity of a column in the moving direction of the base without significantly increasing the overall weight. It is to provide an automated warehouse that can.

[0006]

In order to achieve the above object, the present invention provides a column with a truss-like member.

That is, in the automatic warehouse according to the first aspect of the present invention, a base that moves in the left-right direction along a storage rack having a plurality of storage shelves arranged vertically and horizontally, and a lower end portion is fixed to the base. And a column body extending in the vertical direction, an elevating body provided on the column body so as to be movable in the vertical direction along the column body, and an entrance / exit body provided on the elevating body for taking an article in and out of the storage rack. In an automatic warehouse having an article depositing and receiving body, the main material extending in the up-and-down direction to connect the upper end of the pillar and the base, and the main material and the pillar are slanted. A truss-shaped member having a diagonal member connected to the column is provided so as to project from the column along the moving direction of the base.

According to a second aspect of the present invention, in addition to the structure of the first aspect of the automatic warehouse described above, a horizontal member for horizontally connecting the pillar and the main member is provided. The end of the horizontal member on the side of the main member and the end of the diagonal member on the side of the main member are fastened together and fixed to the main member.

[0009]

As described above, in the automatic warehouse according to the present invention having the above-mentioned structure, the main material extending vertically and connecting the upper end of the pillar and the base is slanted, and the main material and the pillar are slanted. By providing the truss-shaped member having a diagonal member to be connected so as to project from the pillar along the moving direction of the base,
It is possible to effectively increase the bending rigidity of the column in the moving direction of the base without significantly increasing the overall weight. Therefore, it is possible to effectively prevent the column body from shaking without hindering the smooth movement of the article depositing / dispensing body in the left-right direction, and thereby, it is possible to smoothly and surely place the article in / out of the storage shelf. Becomes

According to the second aspect of the present invention, the bending rigidity of the pillar can be further increased by providing the horizontal member that horizontally connects the pillar and the main member. Further, since the end of the horizontal member on the main material side and the end of the diagonal member on the main material side are fastened together, the truss-shaped member can be efficiently assembled to the pillar. It is possible.

It becomes possible to take out the articles 20, and when the articles 20 are to be extracted and inspected, the articles 20 to be taken
Each article 20 can be efficiently extracted at a time by moving the article 20 to the take-out shelf 16 and taking out the article from the take-out shelf 16, so that it is possible to perform the sampling inspection efficiently.

Next, the operation of the automatic warehouse according to this embodiment constructed as described above will be described.

The article depositing / delivering body 100 combines the movement of the base 60 in the left / right direction, the up / down movement of the elevating / lowering body 80, and the movement of the loading / unloading body 90 in the front / rear direction to combine the article loading / unloading position A. The articles 20 carried in are received and delivered to the respective storage shelves 10, or the articles 20 taken out from the storage shelves 10 are transferred to the article unloading position B and the articles 20 are delivered there.

Item delivery unit 100 When moving at an accelerated or decelerated position, a column 70
A force acts on the upper part of the lower part in the moving direction of the article depositing / dispensing body 100 as a base point. However, in the present invention, the truss-shaped member 180 is provided on the pillar 70,
Since the bending rigidity of the article depositing / dispensing body 100 in the moving direction is effectively increased, the bending of the columnar body 70 due to such a force is suppressed. As a result, it is possible to prevent the situation in which the pillar body 70 is swaying when the article depositing / dispensing body 100 is stopped, and it is possible to smoothly and reliably take the article 20 in and out of the article dispensing / dispensing body 100.

An embodiment of the automatic warehouse according to the present invention has been described above. However, the automatic warehouse according to the present invention is not limited to the specific mode of the embodiment, and various modifications can be made. Of course.
