A transfer device 16 and a transfer device 17 are provided side by side on the lifting platform 14. The transfer device 16 moves the container 7 facing the front surface 4 of the shelf in the shelf booth 2 from the shelf booth 2 to the loading / unloading platform 14
The moving device 17 is for moving the container 7 in the back.
This is for moving b in the shelf booth 2 to a position facing the front surface 4 of the shelf. That is, the container 7a is directly transferred to the lifting platform 14 by the transfer device 16, but the container 7b is once moved to the position occupied by the container 7a by the transfer device 17 and then moved up and down by the transfer device 16. Transferred to the loading platform 14.

Next, the structure of the transfer device 16 will be described. Figure 4
3 is a schematic sectional view taken along line IV-IV in FIG. 3, and FIG.
And FIG. 8 is an end view thereof. As can be seen from these figures and FIG. 3, a guide rail 18 is arranged in parallel with the central portion between the support members 15 on both sides, and an engaging block 19 slides back and forth on the guide rail 18. . On the engagement block 19, a pair of left and right engagement pieces 20 are pivotally mounted symmetrically with respect to the guide rail 18 so that they can be expanded and contracted.
Engaging rollers 21 oriented upward are provided at the respective tips. In FIG. 5, the engaging block 19 is the guide rail.
The state is shown when it is located at the rear end of 18 (the right end in the figure). In the figure, the engagement block 19 is at the intermediate position and the tip position, that is, the same position as in FIGS. The state at the time is also shown as engagement blocks 19a and 19b, respectively.

As shown in FIG. 9, the left and right engaging pieces 20 are axially supported by the engaging block 19 via integral pivots 22, respectively, and these pivots 22 have gears 23 of the same shape meshing with each other. Via one gear (only one gear 23 is shown in FIG. 5). A pinion 24 is further fixed to either one of the two pivots 22, and the pinion 24 meshes with a rack 25 extending in the left-right direction. Therefore, when the rack 25 slides to the left and right, the pair of engaging pieces 20 are given the expanding and contracting movements as described above.

A slanting rail 26 that is inclined with respect to the guide rail 18 is disposed beside the guide rail 18. The distance between the oblique rail 26 and the guide rail 18 is wide at the rear end and narrow at the front end. Driven sprockets inside both ends of the diagonal rail 26
27 is rotatably pivotally mounted and is adjacent to the driven sprocket 27 at the rear end, and is a drive sprocket 28 and an idler sprocket 29.
Is provided, and the endless chain 30 is bridged over these sprockets (FIGS. 6 and 7). The drive sprocket 28 is connected to an advance / retreat motor 32 via a coupling 31 and is driven by the advance / retreat motor 32. A drive block 33, which is slidably fitted on the oblique rail 26, is attached to the endless chain 30. Therefore, when the advancing / retreating motor 32 is operated, the drive block 33 travels back and forth on the skew rail 26 according to the rotation direction of the advancing / retreating motor 32.

The drive block 33 is connected to the rack 25 of the engagement block 19, and the engagement block 19 is driven by the drive block 33 via the rack 25 and travels back and forth on the guide rail 18. For example, when the engagement block 19 is driven by the drive block 33 to advance on the guide rail 18 from the rear end position (right end position) shown in FIG. 5 to the front end position 19b via the intermediate position 19a, the drive block 33 is moved in response to the advance. Since the distance between the engagement block 19 and the engagement block 19 is gradually shortened, the rack 25 is gradually pushed into the engagement block 19 and the pinion 24
By the mechanism composed of the gears 23 and the gears 23, the left and right engaging pieces 20 gradually expand from the rearward parallel state at the rear end, and after the state of linearly expanding to the left and right at the intermediate 19a, the frontwardly moving toward the front. Then, the front end 19b becomes parallel to the front. That is, the engagement piece 20 is in a state of being engageable with the container 7 of the front shelf booth 2 at the front end position and with the container 7 of the rear shelf booth 2 at the rear end position.

The guide rails 18 are attached to a pair of front and rear lifting pieces 34.

The lifting piece 34 is also provided with a vertical rack 37, and the rack 37 is engaged with pinions 39 provided at both ends of a rotary shaft 38 which is pivotally supported by the bracket 35 and extends parallel to the guide rail 18. is doing. The rotating shaft 38 is driven by a lifting motor 40 via gears 41a and 41b to rotate forward and backward. With this configuration, the lifting motor
When 40 is operated, the guide rail 18 moves up and down together with the engaging block 19 in accordance with the rotation direction thereof, but in order to allow this ascending / descending movement, the engaging block 19 and the drive block 33 have a guide piece 42 similar to the guide piece 36. Are connected to each other so as to be vertically movable.

When the container 7a of FIG. 3 is transferred onto the lifting platform 14 by the transfer device 16 described above, the guide rail 18 is lowered and the engaging block 19 is moved to the container 7a side. The mounting device 16 is directly faced to the container 7a, and the height of the lifting platform 14 is set so that the surfaces of the supporting members 6 and 15 are at the same height. At this time, the engaging roller 21 of the engaging piece 20
Is at a lower position than the handle 8b (FIG. 2) below the container 7a, the engaging block 19 is slightly advanced to push the engaging roller 21 to the lower side of the handle 8b, and then the lifting motor 40 is operated. Then, when the guide rail 18 is raised, the engagement roller 21 engages with the handle 8b.

When the advancing / retreating motor 32 is operated in this state and the engaging block 19 is retracted along the guide rail 18, the container 7a slides on the supporting members 6 and 15 from the shelf booth 2 to the hoisting and loading platform 14. When the engaging block 19 reaches the rear end of the guide rail 18, it is completely transferred onto the lifting platform 14. During this time, the left and right engaging pieces 20 perform the expanding and contracting movements as described above, but the engaging roller 21 is not disengaged from the handle 8b. Engagement roller 21 after transfer is completed
The guide rail 18 may be returned to the lowered position by the lifting motor 40 in order to disengage the handle 8b. The length of the lifting platform in the front-rear direction may be the length of one container, and this loading platform allows loading and unloading of containers to and from both front and rear shelves, so the shelf passage 5 is sufficiently narrowed for storage. The efficiency can be increased.

In a procedure reverse to the above, the container 7a on the lifting / lowering platform 14 can be transferred to the shelf booth 2 while pushing the end surface of the container 7a by the engagement roller 21.

When the container 7a is taken out from the shelf booth 2, the container 7b remains in the shelf booth 2 as it is. In order to carry out the container 7b, first, the container carrier 11 is moved along the traveling rail 9, and the moving device 17 is directly opposed to the front surface of the shelf booth 2 as shown in FIG.

The width may be almost the same as the height and width of the container 7b, so that the number of stages and the number of rows of the shelf booth 2 can be increased to improve the storage efficiency.

The slide members 44, 45 have such a height that the hook 46 at the tip is located between the handles 8a and 8b, and therefore do not interfere with the lower part or the upper part of the shelf booth 2 and the shelf booths. Enter within 2. Then, when the hook 46 hits the end face of the container 7b, the entire lifting platform 14 is slightly raised so that the hook 46 engages with the handle 8a. Next, when the slide drive motor 43 is reversely rotated to reduce the slide members 44 and 45, the container 7b slides on the support member 6 and moves inside the shelf booth 2 toward the front side.

The movement is stopped when the container 7b reaches the storage position of the container 7a, that is, the positions where the handles 8a and 8b face the front surface 4 of the shelf. At this time, slide members 44, 45
Is out of the front surface 4 of the shelf.
After slightly lowering 14 to disengage the handle 8a from the hook 46, the slide members 44 and 45 are completely retracted onto the lifting platform 14. Thus, since the container carrier 11 can travel along the front surface 4 of the shelf, as shown in FIG.
Is moved to a position directly facing the shelf booth 2, and the container 7
The container 7b is transferred onto the support member 15 of the lifting platform 14 by the same operation as in the case of a. At this time, the container 7a taken out previously is temporarily placed in another vacant shelf booth,
