Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The trolley storage device 10 shown in FIGS. 1 to 5 includes a trolley storage rack 11 and a lifter 12. The cart D is loaded with stored items (not shown), and wheels Db are provided at the four corners of the bottom plate Da.

The trolley storage shelf 11 has a plurality of trolley loading shelves 22 which are guided by an upper rail 20 and a lower rail 21 which are oval in a plane and circularly move.

The trolley loading rack 22 is a horizontal fork-shaped trolley loading plate 2
3, 23 and a vertical trolley backrest plate 24 are formed in an L-shaped cross section, and two free wheel type rollers 25, 25 (one of which is not shown) traveling on the lower rail 21 are mounted on the trolley loading plate 23, 23 on the lower surface. Dolly backrest plate 2
On the upper portion of 4, there are attached holders 29, 29 for holding the carriage so as to sandwich it from both sides. The trolley loading plate 23 may be slightly raised so that the trolley D leans against the trolley backrest plate 24. Further, the trolley loading plate 23
Is composed of two elongated plates, but it may be one plate.

The carriage loading shelves 22 are connected to each other by a link 26 at a portion of a shaft 25a that pivotally supports a roller 25. A sprocket 28 that is rotated by a motor 27 is engaged with the shaft 25a.

The lifter 12 is installed at the carry-in / carry-out position of the carriage D, and the bottom plate Da of the loaded carriage D is attached to the upper surface 23a of the carriage loading plate 23.
It can be raised to a higher position, and two guide grooves 30, 30 for introducing the carriage D are formed on the upper surface 12a. The lifter 12 has a lift stopper link 31
A support shaft 32 for rotatably supporting and a lowering stopper 33 biased so as to project from the upper surface 12a are provided. The lowering stopper 33 is formed with a claw (not shown) that prevents the lowering stopper 33 from protruding more than necessary. One end of the lift stopper link 31 and an engagement piece 35 that engages with the fall stopper 33 are fixed to the lifter base 34 that supports the lifter 12.

Next, the operation will be described.

In order to store the dolly D, first, the lifter 12 is lowered so that the upper surface 12a is flush with the floor G, the lift stopper ring 31 is retracted from the upper surface 12a, and the lower stopper 33 is placed.
After projecting, the truck 12 is loaded on the lifter 12.
During this time, the desired cart loading rack 22 is circularly moved by the motor 27 to just above the lifter 12. In order to prevent danger, the loaded dolly D is prevented from approaching the dolly loading shelf 22 by the lowering stopper 33, and enters the warehousing standby state.

Next, the lifter 12 attaches the bottom plate Da of the carriage D to the carriage loading plate 2
3 to a position slightly higher than the upper surface 23a. As the lifter 12 moves up, the lift stopper link 31 projects from the upper surface 12a to prevent the carriage D from falling. When the lifter 12 rises to a predetermined position, the lowering stopper 33
Engages with the engaging piece 35 and sinks from the upper surface 12a. After that, as shown in FIG. 4, the dolly D is pushed from the position indicated by the solid line to the position indicated by the imaginary line to move it right above the trolley loading plate 23, and the lifter 12 is lowered. As a result, the dolly D has a bottom plate Da.
Is supported by the trolley loading plate 23, and the side surfaces Dc, Dc are held by the holders 29, 29 and stored in the trolley storage rack 11.

In order to take out the trolley D, the desired trolley loading rack 22 is moved to a position right above the lifter 12 as shown in FIG. 2 to raise the lifter 12 and lift the trolley D from the trolley loading plate 23. Then, the carriage D is moved from the position indicated by the imaginary line in FIG. 4 to the position indicated by the solid line. At this time, the lift stopper link 31 projects from the upper surface 12a of the lifter 12,
The trolley D is prevented from falling, and the trolley D is put in the exit waiting state. When the carriage D separates from the carriage loading plate 23, the lifter 12 descends and becomes flush with the floor G. As a result, dolly D
Can be issued.

Next, FIG. 5 to FIG. 7 show a trolley storage device 110 of another embodiment including a slope platform 40, and since the other parts have the same configuration as the trolley storage device 10, the same parts are the same. The reference numerals are attached and the description is omitted. However, since the lifter does not have a rising stopper link, a support shaft, and a lowering stopper, reference numeral 112 is attached. Further, since the lifter base does not have the engaging piece 35, the reference numeral 134 is attached. An inclined portion 40a is formed on the upper surface of the slope base 40.
The height of the trolley storage shelf side (row) end 40b of the inclined portion 40a is set to a height that supports the bottom Da of the trolley D higher than the trolley loading plate upper surface 23a, and the height of the other end 40c. Is lower than its height.

The operation of the trolley storage device 110 will be described.

In order to store the dolly D, first, the desired dolly loading shelf 22 is moved right above the lifter 112 in the lowered state. next,
After the lifter 112 is raised and the upper surface 112a is at the same height as the slope base 40, the carriage D is pushed to raise the slope base 40 and move it to the carriage loading plate 23 (fifth position).
Figure). After that, when the lifter 12 is lowered, the truck D is loaded with the bottom plate Da being supported by the truck loading rack 22 (FIG. 7). As a result, the carriage D is stored in the carriage storage rack 11.

When unloading the trolley D, the desired trolley loading rack 22 is moved to a position right above the lifter 112 in the lowered state and the lifter 112 is moved.
To raise the dolly D from the dolly loading plate 23 as shown in FIG. After that, the dolly D is moved from the lifter 112 to the slope base 40, and the dolly D is taken out. In addition, dolly D
The lifter 112 after unloading the vehicle is lowered so as not to hinder the circulation movement of the other racks carrying the truck D.

Instead of the slope table 40, the floor Ga may have the same height as the slope table 40, as shown by an imaginary line in FIG. Therefore, the concept of the "storage / delivery stand" in the scope of claims for utility model includes not only the slope stand described as an embodiment but also the floor having the same height as the slope stand.

According to this trolley storage device 110, since the trolley D can be directly loaded / unloaded to / from the trolley loading shelf 22, the loading / unloading time is shortened, and the lifting stopper link, the support shaft, the lowering stopper, etc. are not required. , The width of the lifter is the width of one truck (the lifter 12 of the first embodiment is the truck D
It is necessary to have a width of two trolleys in order to make the vehicle stand by once. )
And so on.

Although the lifters 12 and 112 of any of the truck storage devices 10 and 110 are installed at the corners of the truck storage rack 11 as described above, even if a plurality of lifters 12 and 112 are installed in a straight line portion so that loading and unloading can be performed quickly. Of course good things.

Effect of the Invention As described above, in the trolley storage device of the present invention, since the bottom of the trolley is loaded and supported on the trolley loading plate, the trolley does not pop out while the trolley loading rack is moving, and the lock mechanism is not required. .

Since the dolly is stably supported on the dolly loading shelf, the stored items loaded on the dolly are not damaged.

Further, since the wheels are floated from the floor, it is not necessary to make the floor around the trolley storage device flat and firm.

The circulatory movement of the cart loading rack is small.

In addition, when the loading / unloading stand is provided, the truck can be loaded / unloaded directly to / from the truck loading rack, and the loading / unloading time can be shortened.

The width of the lifter can be the width of one trolley, and the trolley storage device can be downsized as a whole.

And so on.
