Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a component of a rack device such as an automated warehouse.

[0002]

[Conventional automated warehouse]

 The following are known as conventional automatic warehouses. That is, it has a rack device that has a large number of article storage shelves vertically and horizontally, and a stacker crane that is installed left and right in front of the rack device. It has a base, a sliding body provided on the lifting platform and movable back and forth, and a fork body provided on the sliding body, and the article storage shelf is of the same level fixed to a column. One beam member that is long in the left-right direction that is common to a plurality of article storage shelves, and is arranged in a cantilever manner so that it is lined up with a predetermined interval in the left-right direction and that the stacker crane side is the free end. The fork body is composed of a large number of horizontal support rods, and the fork body is provided with a base horizontal bar provided on the sliding body, and the base horizontal bar is arranged at predetermined intervals in the left-right direction and protrudes toward the article storage shelf side. To do Those having a plurality of horizontal support bars provided on cantilevered are known.

[0003]

[Disadvantages of the prior art]

 The conventional article storage shelves of the automated warehouse have the following drawbacks. That is, an article storage shelf is fixed to a column, is common to a plurality of article storage shelves on the same stage, and has one long beam in the left-right direction and a large number of cantilevered horizontal beams provided on this beam. Since it was made up of bearing rods and was very heavy, it was difficult to transport, and it was difficult to assemble at the construction site.

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. This invention is composed of four pillars standing upright and rearward and rightward and leftward at a predetermined interval, support pieces attached to these pillars so as to be located in the same virtual horizontal plane, and these pairs. It has a unit shelf to be placed on a support piece, and the unit shelf is a cantilevered horizontal support rod that is arranged in a row on the base horizontal bar and at predetermined intervals on the base horizontal bar. And have.

[0005]

[Function of the device]

 This device has the following actions. Since the article storage shelves are unitized and lightweight, they are easy to transport, and even at the construction site, it is sufficient to place the lightweight unit shelves on the support pieces after erecting the columns. , Easy to assemble.

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this embodiment, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side of FIG. As shown in FIGS. 1 to 3, a pair of front and rear rack devices 1 are arranged at a predetermined interval in the front and back, and each of these rack devices 1 includes a large number of front columns 2 arranged side by side at a predetermined interval and these front columns. The rear struts 2 arranged behind the stanchions 2 with a predetermined space between them, and the left and right parts of the struts 2 at predetermined intervals in the height direction and belonging to the same stage. A support piece 3 having an L-shaped cross section, which is attached so as to be located in the same virtual horizontal plane, and a unit shelf 4 placed on the support pieces 3 forming a set of four located at the corners of the virtual rectangular plane And have.

As shown in FIG. 2 and FIG. 3, the unit shelf 4 has a base horizontal bar 5 which is long in the left-right direction, and is arranged at predetermined intervals on the base horizontal bar 5, and a stacker crane described later. It has a large number of horizontal support rods 6 which are provided in a cantilevered manner so that the free end faces the 18 side. As shown in FIG. 4, an anti-slip member 7 made of synthetic rubber or the like and having an inverted U-shaped cross section is fitted over the horizontal support rod 6. The front and rear entrances 8 of the unit shelves 4 of the rack device 1 face each other (see FIG. 1).

As shown in FIG. 1, a pair of upper and lower guide rails 17 are provided above and below the rack device 1, and a stacker crane 18 is guided by these guide rails 17 so as to be movable left and right. The stacker crane 18 has one mast 19 (if necessary, two erected upright at a predetermined interval). A flat rectangular elevator 20 is guided by this mast 19 so that it can be moved up and down. There is.

As shown in FIGS. 2 and 3, a slide body 22 is provided on the lift table 20 so as to be movable back and forth by a known slide mechanism 23, and a pivot shaft 24 is erected on the slide body 22. A fork body 25 is provided on the pivot 24 so as to be horizontally rotatable, and the fork body 25 is horizontally rotated by a motor 26. The fork body 25 has a base horizontal bar 27 fitted to the pivot 24, and a large number of horizontal support bars 28 provided on the base horizontal bar 27 in a cantilever manner so as to be arranged at predetermined intervals. . The horizontal support rods 28 are vertically movable by passing between the horizontal support rods 6. As shown in FIG. 4, an anti-slip material 29 made of synthetic rubber or the like and having an inverted U-shaped cross section is fitted over the horizontal support rod 28.

As shown in FIG. 1, a loading / unloading station 31 is provided on the right side of each of the rack devices 1, and an article transporting conveyor 32 is installed in each of the loading / unloading stations 31. Each of the article transport conveyors 32 has a base frame 33 and a large number of drive rollers 34 provided in a cantilever manner on the base frame 33 with its free end facing the stacker crane 18 side.

[0011]

[Operation of the embodiment]

 Next, the operation of the embodiment will be described. First, a case where the article W stored in the unit shelf 4 is carried out to the carry-in / carry-out station 31 will be described. The stacker crane 18 moves toward a predetermined unit shelf 4, and the lifting table 20 moves up and down to match the horizontal center of the lifting table 20 with that of the unit shelf 4, and the envelope upper surface of the horizontal support rod 28. More specifically, the upper surface of the envelope of the anti-slip material 29 is located slightly lower than the upper surface of the envelope of the horizontal support rod 6 of the unit shelf 4, more specifically, the upper surface of the envelope of the anti-slip material 7. Further, during that time, the sliding body 22 moves to the center in the front-rear direction, and the horizontal support rods 28 of the fork body 25 direct their free ends toward the unit shelf 4. At that time, the horizontal position of the horizontal bearing rod 28 is adjusted so that the horizontal bearing rod 28 does not overlap the horizontal bearing rod 6 in the vertical direction. After that, when the fork body 25 projects toward the unit shelf 4 and the horizontal support rod 28 is positioned below the article W, the lift 20 is slightly raised and the article W is lifted by the fork body 25. Next, when the fork body 25 retreats, the article W is taken out from the unit shelf 4. After that, the stacker crane 18 moves to the loading / unloading station 31, and the horizontal support rod 28 stops at the position facing the drive rollers 34. At the same time, the lift table 20 moves up and down, and stops when the fork body 25 is positioned slightly above the transport surface of the drive roller 34. After that, when the fork body 25 protrudes and positions the article W 1 above the drive roller 34, and then the fork body 25 (elevation table 20) descends, the article W 1 is lowered onto the drive roller 34. After that, the fork body 25 retracts. Then, the article transport conveyor 32 is driven to transport the article W to the carry-out end of the article transport conveyor 32. After that, the article W is transferred to another conveyor by a robot hand or a human hand. The article W can be stored in the unit shelf 4 by the operation reverse to the above.

[0012]

[Effect of device]

 The present invention has the following effects due to the configuration as described above. Since the article storage shelves are unitized and lightweight, they are easy to transport, and even at the construction site, it is sufficient to place the lightweight unit shelves on the support pieces after erecting the columns. , Easy to assemble.
