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, is supported and guided by rails, and can travel on a fixed path in front of a shelf.

[0002]

2. Description of the Related Art Conventionally, as this type of loading / unloading device,
For example, there is one disclosed in JP-A-63-160911. That is, the loading and unloading device is a traveling body that is supported and guided by the floor rails and can travel on a fixed path in front of the shelf.
It is formed of a pair of front and rear rectangular cylindrical posts (supports) standing upright from the traveling machine body, and an elevating body which is arranged between the posts and has a retractable and retractable tool. This elevating body is guided up and down by both posts via guide rollers.

In the above-mentioned loading / unloading device, if the total height of the loading / unloading device is high, the total length of the post becomes very long. Therefore, as shown in FIG. 8, both posts 51 are respectively formed into an upper post 51a and a lower post 51b. Split and upper post
The square upper flange 52 provided at the lower end of the 51a and the square lower flange 53 provided at the upper end of the lower post 51b are connected. That is, the upper flange 52 is the upper post
The lower flange 53 was externally fitted and welded to the lower end, and the lower flange 53 was externally fitted and welded to the upper end of the lower post 51b. Also,
The upper flange 52 and the lower flange 53 were connected and fixed by bolts and nuts 54 with their joint surfaces abutting against each other.

[0004]

However, in the above-mentioned conventional type, when the upper flange 52 is welded to the upper post 51a and the lower flange 53 is welded to the lower post 51b, the respective flanges 52, 53 are loose. However, there are problems that the welding position is displaced and the flanges 52 and 53 are inclined. Further, when the upper flange 52 and the lower flange 53 are connected by the bolts and nuts 54, there is a problem that the upper flange 52 and the lower flange 53 are connected in a state of being displaced by an amount of play of the bolt hole 55.

Due to the above problems, the upper post 51a
A step is formed at the connecting portion between the lower post 51b and the lower post 51b, and when the lifting body passes through this connecting portion, the lifting body vibrates or generates noise.

The present invention solves the above-mentioned problems, and each flange can be accurately attached to each divided post, and the flanges attached to each divided post can be accurately connected to each other. The purpose is to provide a device.

[0007]

In order to solve the above problems, the loading / unloading device according to the present invention is a loading / unloading device that is supported and guided by a floor rail and can travel on a fixed path in front of a shelf. It consists of a post erected from this traveling machine body and an elevating body having a retractable device that is guided to the side of the post, and divides the post into an upper post and a lower post. Attach a flange, attach a lower flange to the upper end of the lower post, which is detachably connected to the upper flange via a fixture, form a groove into which the lower end of the upper post fits, and attach the lower post to the upper flange. A groove into which the upper end is fitted is formed, and a concave-convex fitting portion is formed on the joint surface between the upper flange and the lower flange.

[0008]

With the above structure, when the upper flange is welded to the upper post, the lower end of the upper post is fitted into the groove of the upper flange to prevent rattling of the upper flange. It is possible to prevent problems such as tilting. Similarly, when the lower flange is welded to the lower post, by fitting the upper end of the lower post into the groove of the lower flange, rattling of the lower flange can be prevented, so that the welding position shifts or the lower flange tilts. You can prevent problems.

Then, the joint surface of the upper flange and the joint surface of the lower flange are joined to each other so that the concave and convex fitting portions of both joint surfaces are fitted to each other, so that the upper flange and the lower flange are joined together without being displaced. It After that, the upper flange and the lower flange are connected and fixed by a fixture.

Thus, the upper post 11a and the lower post 11 are
The loading / unloading device 5 assembled by connecting with b is run on the fixed path 4 to elevate the elevating / lowering body 14, and the loading / unloading device 13
By loading and unloading in the lateral direction, the load 7 can be loaded and unloaded from the intended storage section 6 of the shelf 3.

In the above embodiment, the post 11 is replaced by the upper post 11a.
The lower post 11b is divided into two stages, but the post may be divided into three stages or more and the divided posts are connected by the flanges 31 and 33.

[0022]

As described above, according to the present invention, when the upper flange is welded to the upper post, by fitting the lower end of the upper post into the groove of the upper flange, the rattling of the upper flange can be prevented. It is possible to easily prevent problems such as displacement of the welding position and inclination of the upper flange.
Similarly, when the lower flange is welded to the lower post, by fitting the upper end of the lower post into the groove of the lower flange, rattling of the lower flange can be prevented, so that the welding position shifts or the lower flange tilts. Defects can be easily prevented.

Further, by joining the joining surface of the upper flange and the joining surface of the lower flange to fit the concave and convex fitting portions of both joining surfaces, the upper flange and the lower flange are joined together without displacement. It After that, the upper flange and the lower flange are connected and fixed by a fixture.

As described above, since the upper flange can be accurately attached to the upper post and the lower flange can be accurately attached to the lower post, and the upper flange and the lower flange can be accurately connected, the connecting portion between the upper post and the lower post can be accurately connected. There is no step in the vertical direction, and the lifting / lowering body smoothly passes through this connecting portion, so that noise and vibration are prevented from occurring when passing through the connecting portion.
