Adjacent. Further, as shown in FIGS. 11A and 12, a load restraining plate 39 for positioning the rear end position of the load to be placed first is erected at the rear end of the third loading platform 6.
[0016]
The plate material 15 of the fixed load platform 7 and the plate materials 18, 27, 32 of the movable load platforms 4 to 6 are not essential, and may be omitted depending on the load to be handled. It may be a thing. In the illustrated embodiment, the loading surfaces of the loading platforms 4 to 7 are configured to incline in parallel with the inclined rails 2a and 2b. However, the support level on the front end side is raised to be horizontal. It can also be configured.
[0017]
In FIG. 4, the fluidized shelf configured as described above shows a state in which each of the movable loading platforms 4 to 6 is moved slightly upward and inclined, but the lowermost movable loading platform 4 includes a pair of left and right lower ends of the rear end. The shock absorber elastic body 23 is moved to the lower limit position where it abuts against the rear end cross member 14 of the fixed load platform 7, so that it substantially overlaps the fixed load platform 7. When the front surfaces of the pair of brackets 36 move to the lower limit position where the front surfaces of the lowermost movable load platform 4 come into contact with the pair of contacted surfaces 24 on the left and right sides of the lowermost movable load platform 4, the lowermost movable load platform 4 is almost completely overlapped. Further, the third cargo bed 6 moves to the lower limit position where the front surfaces of the lower ends of the brackets 38 on the left and right sides of the front end abut against the abutted surfaces 37 on the rear side of the lower ends of the brackets 35 on the front left and right sides of the second load platform 5. Almost completely with respect to the second loading platform 5. Become that state. Therefore, when each of the loading platforms 4 to 7 is in an empty state, all the movable loading platforms 4 to 6 are overlapped on the stationary loading platform 7 as shown in the lowermost flow shelf unit 1 in FIG. It can be done.
[0018]
The method of using the above-described fluidized shelf is the same as that of a conventional fluidized shelf of this type, and the first load is placed on the third carrier 6 located at the uppermost position on the fixed carrier 7 with a forklift or the like. . The second load loading operation is the second load supported by a forklift or the like, and the third loading platform 6 is pushed up together with the load on the inclined rails 2a and 2b so as to push upward. When the third loading platform 6 is moved backward from above the second loading platform 5, the second loading supported by a forklift or the like is lowered and placed on the second loading platform 5. The third load loading operation is also performed in the above manner by pushing the third loading platform 6 and the second loading platform 5 together with the loads thereon so as to push up the inclined rails 2a and 2b. When the second loading platform 5 is moved backward from above the loading platform 4, the third load supported by a forklift or the like may be lowered and placed on the lowermost movable loading platform 4. The fourth load is lowered and placed on the fixed load bed 7 after pushing the movable load beds 4 to 6 on which the load is loaded so as to push up the tilted rails 2a and 2b. I can do it.
[0019]
In the state in which the load is placed on all the loading platforms 4 to 7 as described above (refer to the second-stage and third-stage fluidized shelves 1 in FIG. 1), the respective loads are placed. It is blocked by the load on the fixed platform 7 that the movable platforms 4 to 6 move downward on the inclined rails 2a and 2b by gravity. When the load on the fixed platform 7 is carried out from such a state by a forklift or the like, each of the subsequent movable platforms 4 to 6 on which the subsequent loads are placed moves downward on the inclined rails 2a and 2b by gravity. When the lower movable platform 4 reaches the lower limit position that overlaps the fixed platform 7 and stops, the load on the lower movable platform 4 can be carried out. Similarly, when the load on the lowermost movable loading platform 4 is carried out, the second loading platform 5 moves to the lower limit position on the fixed loading platform 7, so that the loading of the load from the second loading platform 5 is carried out. Since the work can be performed and the load on the second loading platform 5 is carried out, the third loading platform 6 moves to the lower limit position on the fixed loading platform 7, so that the loading work from the third loading platform 6 is carried out. Can be done.
[0020]
In addition, according to said embodiment, the 2nd load platform 5 and the 3rd load platform 6 which slide on the inclination rails 2a and 2b inclining downward are the contacted surfaces of the lowermost movable load platform 4 and the 2nd load platform 5, respectively. The impact received when received by the contact surfaces 24 and 37 is transmitted to the fixed platform 7 (fixed frame side) via the buffer elastic body 23 of the lowermost movable platform 4. That is, the abutted surfaces 24 and 37 are only required to be able to suppress the generation of abnormal noise at the time of collision, and therefore, in all the movable load platforms 4 to 6, the lower limit position overlaps with the fixed load platform 7. Compared with the case where the elastic body for buffering which receives each movable carrier 4-6 when it reaches | attains, it can comprise at low cost.
[0021]
【The invention's effect】
The present invention can be implemented and used as described above, and according to the fluidized shelf with a movable bed according to the present invention, the bed itself is more than the other upper movable bed in relation to the wheel position. Since the platform surface width of the bottom movable platform having a narrow width is made substantially the same as the platform surface width of the other movable platform by the horizontal plate for extending the platform surface projecting from the left and right sides of the bottom movable platform. This eliminates the need to increase the accuracy of the centering of the load only when the load is placed on the lower movable loading platform (loading), and the workability can be improved. Further, even when a load that protrudes laterally from the loading platform surface is placed, there is no possibility that the load contacts the inclined rail and the sliding along the inclined path is not smoothly performed. Moreover, as described in Patent Document 2, not intended to place the wheels rolling on inclined rails on the lower side of the lowermost movable bed of the left and right side edges, the right and left wheels of both sides of the lowermost movable bed Since it is pivotally supported on the lateral end surface, the height of the lowermost movable carrier can be greatly reduced. Therefore, even if the number of stages of the loading platform is the same, the height of the entire fluidized shelf can be reduced, and the stability can be improved.
[0022]
In addition, according to the structure of Claim 2, the structure of a lowermost stage movable carrier becomes very simple, and this invention can be implemented cheaply. Moreover, according to the structure of Claim 3, the structure of each movable carrier except a lowermost stage movable carrier becomes easy, and the position of the wheel which rolls on an inclined rail can also be changed into the both inside and outside of the said inclined rail. It is only necessary to select the mounting position of the bracket with the wheel pivotally supported on the side at the lower end from both the inside and outside of the vertical member arranged on the left and right sides of the loading platform, and the present invention can be implemented at low cost.
[0023]
Further, when adopting the configuration according to claim 3, according to the configuration according to claim 4, the vertical members and the inclined rails constituting each movable cargo bed except the lowermost movable cargo bed are all square pipes of the same size. It can be made of materials to reduce costs. In addition, by combining the configuration described in claim 5, the fixed cargo bed can also be configured at low cost.
