8 to 20 are operation explanatory views for explaining the operation of the above-described embodiment. Hereinafter, the operation of the stacked storage apparatus shown in FIG. 2 will be described with reference to these drawings.
Initially, the storage space 4 is empty, and the pair of elevating arms 19A and 19B are urged by the tension springs 21A and 21B, respectively, and returned to positions where they abut against the stoppers 22A and 22B symmetrically. It is assumed that the pair of lifting plates 25A and 25B coupled to the lifting arms 19A and 19B via the coupling pins 26A and 26B are also in a state of being returned to the lowest position in a bilaterally symmetrical manner. At this time, the pair of transmission arms 17A and 17B fixed to the main shaft 12 together with the pair of elevating arms 19A and 19B are vertically downward symmetrically and are pivotally supported so as to be rotatable relative to the main shaft 12. It is assumed that the arms 13A and 13B are in a substantially vertically downward state with their own weight and symmetrically. Further, the pair of locking members 24A and 24B are biased by the coil springs 39A and 39B, and the stoppers 40A and 40B are returned to the horizontal posture in which the stoppers 40A and 40B abut against the lifting plates 25A and 25B (see FIG. 8). Status).

(1) Storage of first article storage box As shown in FIG. 8, the user puts an article (not shown) into the first article storage box 3 a, and the groove 44 </ b> A from the loading / unloading port 6 of the stacked storage apparatus 1. , 44B are placed on the guide rails 42A, 42B so that they fit into the protrusions 43A, 43B, and inserted into the horizontal movement path 5 (see arrow A in FIG. 8). The outer wall surface 48 on the back side of the article storage box 3a comes into contact with the rotation rollers 15A and 15B supported on the rotation arms 13A and 13B, pushes the rotation arms 13A and 13B backward, and rotates counterclockwise in FIG. It tries to rotate in the first direction (see symbol B in FIG. 8). At this time, the rear end surfaces 130A and 130B of the rotating arms 13A and 13B push the bent portions 18A and 18B of the transmission arms 17A and 17B backward to rotate in the first direction. Since the main shaft 12 is fixed to the transmission arms 17A and 17B, and the lift arms 19A and 19B are fixed to the main shaft 12, the storage space for storing the article storage box 3a against the pulling force of the tension springs 21A and 21B. 4, the transmission arms 17 </ b> A, 17 </ b> B rotate in the first direction symmetrically in the left-right direction, and the lifting arms 19 </ b> A, 19 </ b> B rotate in the first direction symmetrically in the left-right direction. As the elevating arms 19A and 19B rotate, the elevating plates 25A and 25B coupled to the elevating arms 19A and 19B rise symmetrically.

  When the horizontal movement of the article storage box 3a is advanced, when the rotary arms 13A and 13B are rotated from a vertically downward direction to a certain angle, the rotation rollers 15A and 15B are moved to the contact plates 45A and 45B on the upper surface of the article storage box 3a. At this time, the rotation of the rotating arms 13A and 13B is stopped, the rotation of the transmission arms 17A and 17B and the lifting arms 19A and 19B is stopped, and the lifting plates 25A and 25B are stopped. The rise also stops. When the horizontal movement of the article storage box 3a is further advanced, the front rotation rollers 15A and 15B are disengaged from the contact plates 45A and 45B, and the rear rotation rollers 16A and 16B are placed. When placed in the lowermost layer of the space 4 (see FIG. 10), the rotating rollers 16A and 16B are also removed, and the pressing force to the rotating arms 13A and 13B is lost, and the rotating arms 13A and 13B are each rotated by their own weight in the clockwise direction of FIG. It turns to the 2nd direction which is a direction, and returns to the original perpendicular direction. Then, there is no pressing force on the transmission arms 17A and 17B, and the lifting arms 19A and 19B, the main shaft 12, and the transmission arms 17A and 17B are united in the second direction by being urged by the tensile force of the tension springs 21A and 21B. It rotates and stops when the lifting arms 19A and 19B come into contact with the stoppers 22A and 22B, and returns to the original return position (see FIG. 11). At this time, the elevating plates 25A and 25B coupled to the elevating arms 19A and 19B descend and return to the original return position, but the bent portions 37A, 38A, 37B and 38B of the locking members 24A and 24B are en route. Is in contact with the contact plates 45A and 45B of the article storage box 3a, the posture is changed by rotating from a horizontal posture to an obliquely upward direction against the urging force of the coil springs 39A and 39B (in this case, the bent portion 37A). , 38A, 37B, and 38B have a taper formed on the lower surface to reduce the rotation angle, and the posture can be changed smoothly), and the tips of the bent portions 37A, 38A, 37B, and 38B cross the side wall of the article storage box 3a. It descends while sliding (see FIG. 12). Then, when the tips of the bent portions 37A, 38A, 37B, 38B are detached from the article storage box 3a, the springs 39A, 39B are urged to rotate downward and the stoppers 40A, 40B are moved to the lifting plates 25A, 25B. When it comes into contact, the rotation stops and the original horizontal posture is restored.

(2) Storage of second article storage box A user puts an article (not shown) into the second article storage box 3b, and enters the horizontal movement path 5 from the loading / unloading port 6 of the stacked storage apparatus 1. When the outer wall surface 48 of the article storage box 3b comes into contact with the rotating rollers 15A and 15B pivotally supported by the rotating arms 13A and 13B, the tension spring 21A is further inserted (see arrow C in FIG. 13). , 21B against the pulling force of the storage space 4 (see reference numeral D in FIG. 13), the rotating arms 13A, 13B rotate in the first direction symmetrically to the left and right. The transmission arms 17A and 17B pushed by the rear end surfaces 130A and 130B of 13A and 13B rotate in the first direction symmetrically in the left-right direction, and the lifting arms 19A and 19B rotate in the first direction symmetrically in the same direction. Move. As the elevating arms 19A and 19B rotate, the elevating plates 25A and 25B coupled to the elevating arms 19A and 19B rise symmetrically, and the locking members 24A and 24B become the first article symmetrically. The lower surface of the storage box 4a is locked and raised (see FIG. 14).

When the horizontal movement of the article storage box 3b is advanced, when the rotating arms 13A and 13B are rotated from a vertically downward direction to a certain angle, the rotation rollers 15A and 15B are brought into contact with the contact plates 45A and 45B on the upper surface of the article storage box 3b. At this time, the rotation of the rotating arms 13A and 13B is stopped, the rotation of the transmission arms 17A and 17B and the lifting arms 19A and 19B is also stopped, and the lifting plates 25A and 25B are stopped. The rise also stops. The first article storage box 3a is lifted from the bottom of the storage space 4 to the second layer, and an empty space is created immediately below. When the horizontal movement of the article storage box 3b is further advanced, the front rotation rollers 15A and 15B are disengaged from the contact plates 45A and 45B, and the rear rotation rollers 16A and 16B are placed. When placed in the lowermost layer of the space 4 (see FIG. 16), the rotating rollers 16A and 16B are also removed, and the pressing force to the rotating arms 13A and 13B disappears, and the rotating arms 13A and 13B each have their own weight in the clockwise direction of FIG. To return to the original vertical direction. Then, there is no pressing force on the transmission arms 17A and 17B, and the lifting arms 19A and 19B, the main shaft 12, and the transmission arms 17A and 17B are united by being pulled by the tension force of the tension springs 21A and 21B. , And stops when the lift arms 19A and 19B come into contact with the stoppers 22A and 22B, and return to the original return position (see FIG. 17). At this time, the elevating plates 25A and 25B coupled to the elevating arms 19A and 19B are lowered and returned to the original return position, but the bent portions 37A, 38A, 37B and 38B of the locking members 24A and 24B are en route. Is in contact with the contact plates 45A and 45B of the article storage box 3b, the posture is changed by rotating from a horizontal posture to an obliquely upward direction against the urging force of the coil springs 39A and 39B (see FIG. 12). The first article storage box 3a is placed on the second article storage box 3b when the lock on the article storage box 3a is released. Thereafter, the tips of the bent portions 37A, 38A, 37B, 38B of the locking members 24A, 24B descend while sliding on the side wall of the second article storage box 3b. Then, when the tips of the bent portions 37A, 38A, 37B, 38B are detached from the article storage box 3b, the coil springs 39A, 39B are urged to rotate downward, and the stoppers 40A, 40B are moved to the lifting plates 25A, 25B. When it comes into contact, the rotation stops and the original horizontal posture is restored. In the storage space 4, the article storage boxes 3a and 3b are stacked in this order from above (see FIG. 17).
In the same manner, the third, fourth,... Article storage boxes are sequentially stacked in the storage space 4 by putting them into the lowermost layer of the storage space 4 through the horizontal movement path 5 from the outlet 6. Can be stored.

(3) Taking out the lowermost article storage box As shown in FIG. 18, it is assumed that the article storage boxes 3a, 3b, 3c and 3d are stacked in this order in the storage space 4 from the top. When it is desired to take out 3d to the outside, a hand is put into the horizontal movement path 5 from the take-in / out opening 6 and the handle 46 of the article storage box 3d in the lowermost layer of the storage space 4 is held and pulled forward. After the article storage box 3d exits the lowermost layer of the storage space 4 and enters the horizontal movement path 5, the outer wall surface 49 on the near side comes into contact with the rotation rollers 16A and 16B on the rear side of the rotation arms 13A and 13B. When pushed further forward (see arrow E in FIG. 19), the rotating arms 13 and A13B are supported in a non-fixed and relatively rotatable manner with respect to the main shaft 12, and do not come into contact with the transmission arms 17A and 17B. 19 alone, the article storage box 3d can be pulled out toward the loading / unloading port 6 because it is turned away in the second direction which is the clockwise direction in FIG. 19 (see arrow F in FIG. 19). During drawing, the rotating rollers 16A and 16B are placed on the contact plates 45A and 45B from the upper end on the near side of the article storage box 3d, so that they can be pulled out smoothly (see arrow G in FIG. 20). Thereafter, when the upper end on the back side of the article storage box 3d is removed from the rotating rollers 16A and 16B, the rotating arms 13A and 13B rotate counterclockwise in FIG. 20 by their own weight, and return to the original vertically downward state. Return. The article storage box 3d can be taken out through the slot 6 as it is. While the pivot arms 13A and 13B pivot from the vertically downward direction to the first direction and then return to the original return state, the main shaft 12, the transmission arms 17A and 17B, the lift arms 19A and 19B, the lift plates 25A and 25B, The locking members 24A and 24B do not move and remain stationary.

  On the other hand, in the storage space 4, the lowermost layer from which the article storage box 3d is pulled out becomes empty, and the upper article storage boxes 3a, 3b, and 3c are lowered downward by one layer (one box) by their own weight (see FIG. 20). Therefore, these article storage boxes 3a, 3b, 3c can also be taken out from the bottom in order.

According to this embodiment, when a new article storage box 3 is put into the horizontal movement path 5 from the loading / unloading port 6 in a state in which each part is restored and pushed to the lowermost layer of the storage space 4, the rotating arm 13A, 13B is pushed and rotated in the first direction, and in conjunction with this, the transmission arms 17A and 17B, the main shaft 12, and the lifting arms 19A and 19B are rotated in the first direction and coupled to the lifting arms 19A and 19B. The raised / lowered plates 25A and 25B are lifted from the lower return position. When the raising and lowering plates 25A and 25B are lifted, the locking members 24A and 24B pivotally supported at the lower end are lifted in the horizontal direction, and the article storage box 3 already exists in the lowermost layer of the storage space 4. The article storage box 3 is lifted upward to open the lowermost layer of the storage space 4. Almost at the same time when the new article storage box 3 enters the lowermost layer of the storage space 4, the rotating arms 13A and 13B are detached from the new article storage box 3 and rotate in the second direction by their own weights to return to the original vertical position. At this time, the lifting arms 19A, 19B, the main shaft 12, and the transmission arms 17A, 17B are integrally returned to the original return state by being biased by the tension springs 21A, 21B. When the elevating arms 19A and 19B are restored, the elevating plates 25A and 25B are also lowered to return to the original restored state, but when the locking members 24A and 24B come into contact with the new article storage box 3 during the descending, the coil springs 39A, The posture is changed obliquely upward against the urging force of 39B, and the upper article storage box 3 that has been locked is placed on the new article storage box 3. When the locking members 24A and 24B are lowered to the lowest position, the contact with the new article storage box 3 is released, and the stoppers 40A and 40B are biased by the coil springs 39A and 39B so that the stoppers 40A and 40B come into contact with the lifting plates 25A and 25B. Return. As a result, the plurality of article storage boxes 3 can be stored while being stacked one above the other by sequentially inserting them one by one through the single inlet / outlet 6 at the lower part of the apparatus.
On the other hand, when each part is restored and a hand is inserted through the insertion / exit opening 6 and the article storage box 3 at the bottom layer of the storage space 4 is pulled out, it is pushed by the article storage box 3 and is not fixed to the main shaft 12. Since 13A and 13B move independently in the second direction and open the horizontal movement path 5, they can be taken out to the outside without any trouble. When a plurality of article storage boxes 3 are stacked in the storage space 4, each article storage box 3 on the upper side of the article storage box 3 taken out this time is lowered by one box. As a result, the plurality of article storage boxes 3 stacked and stored in the storage space 4 through the single inlet / outlet 6 at the lower part of the apparatus can be taken out one by one in order.

  In the above-described embodiment, the article storage box is described as an example of the storage object. However, the present invention is not limited to this, and a box-shaped article itself may be used. Various modifications are possible, such as making the storage space higher, or providing only one set of the pivot arm and the transmission arm at the center in the left-right direction of the main shaft.

  The present invention can be applied to homes, offices, factories, vehicles, and the like where there are a limited number of places where storage objects can be taken in and out, but a large number of storage objects are stacked one above the other.
