Abstract

PROBLEM TO BE SOLVED: To make a rail parallel to a rack device with high accuracy. SOLUTION: Prior to fastening a bolt 28, a sleeper 25, and in its turn, a rail fixed thereto are freely position-adjusted in a longitudinal direction along a T-shape groove 21. The rail can therefore be made parallel to a rack device with high accuracy. After this position adjustment, the bolt 28 is fastened to fix the rail positively while holding an opening edge part of a T-shape groove 21 of a base member 20 between a nut plate 24 and the sleeper 25.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a rail for a stacker crane in an automatic warehouse.

[0002]

2. Description of the Related Art Conventionally, the following are known as this type of rail mounting structure. That is, there is known one having a sleeper fixed to a floor surface and a rail for a stacker crane (hereinafter, simply referred to as a rail) attached to the sleeper so as to be able to slightly adjust its position.

[0003]

Disadvantages of the prior art The conventional rail mounting structure has the following disadvantages. That is, the rails were fixed to the floor or the like while slightly adjusting the position of the rails with respect to the fixed sleepers. There is a drawback that it may not be possible to arrange them in parallel.

[0004]

The present invention employs the following means to solve the above-mentioned drawbacks. A base member having a T-shaped groove and fixed so that the stacker crane rail intersects with the T-shaped groove and the opening of the T-shaped groove faces the rail side, It has a rail fixing tool fixed to a predetermined position of the base material by engaging with the groove, and the rail fixed to the base material by the rail fixing tool.

[0005]

The first aspect of the present invention has the following functions. Since the mounting position of the rail to the base material can be easily adjusted along the T-shaped groove,
Irrespective of the accuracy of the fixing position of the base material, the rail can be made parallel to the rack device with high accuracy.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In this description, the front means the lower side of FIG. 1, the rear means the upper side of the figure, the left means the left side of FIG. 1, and the right means the right side of the figure.

[0007] A pair of rack devices 1 before and after the automatic warehouse are erected on the floor 7 so that the stacker crane passage 10 is opened. The rack device 1 includes a plurality of front columns 2 arranged side by side at predetermined intervals, and a rear column 2 arranged behind the front columns 2 with a predetermined interval therebetween.
The front and rear supports 2 have a number of article support members 4 provided at predetermined intervals in the height direction, and the article storage shelf 3 is formed by a pair of left and right article support members 4 facing each other without the support columns 2 interposed therebetween. It is configured. A space between the pair of left and right article support members 4 is a fork passage gap 5 that allows the slide fork 17 to be described later to move in the vertical direction. The entrances 6 of the article storage shelves 3 of the front and rear rack devices 1 face each other.

[0008] A pair of upper and lower rails 11 are arranged in the stacker crane passage 10 so that the longitudinal direction thereof is directed to the left and right by means described later in detail. The stacker crane 13
Is a traveling carriage 14, an elevator 16 that can be raised and lowered on a mast 15 provided on the traveling carriage 14, and a slide that is horizontally slidably provided in the elevator 16 by a well-known advance / retreat mechanism. And a fork 17.
As is well known, the slide fork 17 performs an operation of projecting the article W downward and lifting the article W by lifting the elevating platform 16 and retreating to the elevator 16 side.
Can be drawn into the elevating table 16 and the article W can be dropped on the article storage shelf 3 or the like by the reverse operation.

The lower rail 11 will be described with reference to FIGS.
The mounting structure will be described. Stacker crane passage 1
0 on the floor 7 with the longitudinal direction facing the front and back,
In addition, at predetermined intervals in the left-right direction, specifically, at the mounting intervals in the left-right direction of the columns 2 so as to reach the lower part of the columns 2 on the stacker crane passage 10 side of the front and rear rack devices 1, , A long base material 20 is embedded and fixed.

The base member 20 is formed of a channel member having a C-shaped cross section. The base member 20 has a T-shaped groove 21 (in this specification, the T-shaped groove 21 is a protruding edge opposed to an opening edge portion). And a groove having a cross-sectional shape other than a T-shaped groove, including a groove having a protruding edge facing each other at the opening edge.) The base member 20 is fixed to the floor 7 such that the T-shaped groove 21 faces the front-back direction and the opening of the T-shaped groove 21 faces the lower rail 11 side (upward).

A rail fixing member 23 for fixing the rail 11 to the base member 20 contacts a nut plate 24 fitted in the T-shaped groove 21 and the base member 20 so as to face the nut plate 24. Rail 1
1 is fixed, and a bolt 2 screwed into a screw hole 27 of a nut plate 24 through a through hole 26 formed to penetrate the sleeper 25 in the vertical direction.
8 is provided. Needless to say, the left and right widths of the nut plate 24 and the sleeper 25 are larger than the left and right widths of the opening of the T-shaped groove 21.

The rail 11 is fixed to the sleeper 25 at a right angle or substantially at a right angle with the T-shaped groove 21 by a known holding tool 30 having a holding piece or the like.

According to the above configuration, before the bolt 28 is tightened, the rail 11 is raised by freely adjusting the position of the sleeper 25, and thus the rail 11 fixed thereto, back and forth along the T-shaped groove 21. It can be parallel to the rack device 1 with high accuracy. After the position is adjusted, the bolt 28 is tightened, so that the nut plate 24 and the sleeper 25 sandwich the opening edge of the T-shaped groove 21 of the base member 20, and the rail 11
Can be securely fixed.

Although not shown, the upper rail 11 is provided with the same structure as the lower rail 11 so as to be adjustable in the front-rear position with respect to the base member 20.
The base member 20 is transferred to the support 2 on the stacker crane passage 10 side of the front and rear rack devices 1 in a state where the base member 20 is rotated 180 degrees up and down from the state shown in FIGS. 2 and 3. As a result, the upper rail 11, the rail fixture 23
2 is rotated 180 degrees up and down from the state shown in FIGS.

[0015]

[Modifications and the like] Modifications and the like will be described below. (1) The base member 20 may be other than a channel member having a C-shaped cross section. (2) The structure of the holding tool 30 is arbitrary. (3) The rail 11 and the T-shaped groove 21 may intersect at right angles or substantially at right angles.

[0016]

According to the present invention, the following effects can be obtained by the above-described configuration. According to the first aspect of the present invention, the mounting position of the rail with respect to the base material can be easily adjusted along the T-shaped groove, so that the rail can be mounted with high accuracy regardless of the fixing position accuracy of the base material. Can be parallel to According to the second aspect of the present invention, the rail can be securely fixed by holding the base material between the nut plate and the sleeper. According to the third aspect of the present invention, since a commercially available channel material having a C-shaped cross section is used as the base material, the cost can be reduced without the trouble of processing a T-shaped groove or the like.
