Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / unloading device for an automatic warehouse which is installed in a factory and can travel on a fixed path in front of a shelf.

[0002]

2. Description of the Related Art As an automatic warehouse consisting of shelves and a loading / unloading device, a structure shown in, for example, JP-A-63-218406 is provided. That is, the crane, which is a loading and unloading device, has a pair of front and rear columns or a column that are erected from a lower frame or a carriage, and an elevating carriage that is guided by the columns.

The pillar has a rectangular tubular cross section, is provided with groove-shaped guide rail portions in the central portions on both front and rear sides (or both left and right sides), and extends from each corner in the left-right direction (or front-back direction). L-shaped plate portions projecting only to the above are continuously provided, and rail grooves for mounting components are formed in these L-shaped plate portions. The support column is formed of an integral extruded material with its front, rear, left, and right being symmetrical with respect to its cross section.

When such a pillar is adopted as a two-column type, the guide rail portions are erected in a pair in the front and rear direction from the lower frame in the front-back direction (traveling direction), and the guide rail portions are formed. A guide roller for front-rear steadying from the elevator carriage side is brought into contact with the surface facing the elevator carriage side (front-back direction), and a pair of surfaces located on both sides for the left-right steady rest from the elevator carriage side. The guide roller is in contact.

Further, when the pillar is adopted as a single type, the guide rail portion is erected from the dolly so that the guide rail portion is directed in the left-right direction, and a pair of surfaces facing the front-rear direction among the surfaces forming the guide rail portion. Further, the front and back steady rest guide rollers from the lift carriage side are brought into contact with the left and right side steady rest guide rollers from the lift carriage side.

[0006]

According to the above-mentioned conventional structure, since the L-shaped plate portion of the strut adopted in the two-piece type protrudes only in the left-right direction, the strut in the front-rear direction of the strut can be It does not serve to reinforce and therefore causes the column to tilt forward and backward when the crane accelerates or decelerates or stops. In addition, since the L-shaped plate portion of the single-column type support protrudes only in the front-rear direction, it does not serve to reinforce the column in the left-right direction, and therefore the load-transfer running fork is projected. When moving in and out, the column will be tilted in the left-right direction.

[0007] Further, since it is necessary to displace the stanchions by 90 degrees between when adopting the one-column type and when adopting the two-column type, it is easy to make a mistake when erected on the lower frame or the truck. However, it will take time and labor for the installation work.

It is an object of the present invention that the support column can be sufficiently reinforced in both the front-rear direction and the left-right direction when used in any form, and in any form used, it can stand upright. The installation is to provide a loading / unloading device for an automated warehouse that can be easily oriented in the same direction.

[0009]

In order to achieve the above object, an automatic warehouse loading / unloading device according to the first aspect of the present invention comprises a traveling main body composed of a lower frame and a column standing upright from the lower frame. In the front-rear direction, which is the traveling direction of the main body, there is provided a loading and unloading device for an automatic warehouse, which is provided with a carriage that can be raised and lowered along one surface of the front and rear surfaces of the pillar,
The column includes a tubular portion having a rectangular cross section, corner ridges protruding outward in the front, rear, left, and right from respective corners of the tubular portion, and a center in the left-right direction on the front and rear outer surfaces of the tubular portion. It is integrally formed by including a central ridge portion that projects outward in the front-rear direction from the portion.

The second aspect of the present invention is, in the above-mentioned automatic warehouse loading / unloading device of the first aspect, the tubular portion is traversed by a pair of long sides facing each other and a pair of short sides facing each other. The surface is formed in a rectangular shape, and the column is erected on the lower frame with the pair of short sides as the front and rear outer surfaces.

According to the third aspect of the present invention, in the above-mentioned automatic warehouse loading / unloading device of the first aspect, one column is erected on the lower frame, and a shake preventing roller on the carriage side is provided at the corner protrusion. It is disposed so as to be able to come into contact with the surface of the column facing the side opposite to the carriage side and the surface of the column facing the carriage side.

Further, the fourth invention is the above-mentioned first to third inventions.
In the loading / unloading device for an automated warehouse according to any one of the inventions,
The pillars are integrally formed in a lateral cross section so as to be symmetrical in the front-rear direction and in the left-right direction.

[0013]

According to the structure of the first aspect of the invention described above, the loading / unloading device can load / unload a load on / from the shelf by moving the running body and moving the carriage up and down. The force that causes the column to tilt in the front-back direction due to shocks during acceleration / deceleration of the loading / unloading device and at the time of stoppage is due to the reinforcement structure by the corner ridges protruding in the front-back direction from the tubular part of the column, It can be firmly received on the frame side. In addition, when the loading and unloading tool on the carriage is moved in and out in the left and right direction to perform loading and unloading work, the force that the column leans in the left and right direction is the corner protrusion that protrudes in the left and right direction from the tubular portion of the column. In addition to the reinforcement structure by the part, it can be firmly received on the lower frame side. In this way, the support pillar can be erected from the lower frame without tilting in the front-rear direction or the left-right direction.

According to the structure of the second aspect of the present invention, the force by which the support column tilts in the front-rear direction due to an impact at the time of acceleration / deceleration or stop of the loading / unloading device causes the long side portion of the tubular portion to move in the front-rear direction. Therefore, it can be more firmly received by its sufficient length.

According to the structure of the third aspect of the invention, when the carriage is moved up and down, the runout preventing rollers are applied to the surface of the corner ridge portion facing the side opposite to the carriage side and the surface of the support column facing the carriage side. By bringing them into contact with each other, they can be smoothly guided without being unexpectedly shaken in the front-rear direction, even though they are guided by one column.

Further, according to the structure of the fourth aspect of the present invention, at the time of assembling and constructing, the upright of the pillar with respect to the lower frame is related to the one-piece type or the two-piece type only by arranging the long sides thereof in the front-back direction. It can be done in the same direction without having to think about the 90-degree or 180-degree directions.
