[Problems to be Solved by the Invention] As described above, the conventional transfer device requires a plurality of moving tables, a large number of rollers for moving these for each moving table, and a drive mechanism such as a rack and pinion mechanism. Therefore, there are many parts,
The problem is that the structure is complex. Moreover, the configuration is such that a plurality of moving tables are stacked vertically in multiple stages, and at least two of the upper moving tables are inserted between vertically opposing storage shelves, so the insertion space is used between the storage shelves. must be anticipated. Therefore, since a large interval is required between the vertically opposing storage shelves, there is a problem that the height of the three-dimensional storage is large. An object of the present invention is to obtain a delivery device for a three-dimensional storage that has a simple configuration and can reduce the height of the three-dimensional storage.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for moving a pallet, which is attached to a lifting platform and on which the stored items are placed on the upper surface, across a storage shelf and the lifting platform, so that the stored items can be stored. In the transfer device for a three-dimensional storage that takes the items into and out of the storage shelf, the drive unit is mounted on the lifting platform and has a pair of upward output shafts, and rotates the output shafts simultaneously and at the same speed in mutually opposite directions. a pair of swing arms each having one end connected to each of the output shafts and rotating horizontally; a rail extending in the length direction of either the swing arms or the pallet; The slider is provided on the other of the swing arm or the pallet and slidably engages with the rail.

[0006]

In the transfer device of the present invention, when the drive section is operated, the pair of output shafts of the drive section are simultaneously rotated in opposite directions. Since swing arms extending in the radial direction are connected to these output shafts, these arms can be rotated horizontally without changing their height positions. The pair of swing arms and the pallet supported across them are connected via the rail and the slider that slides on the rail, so as the swing arm rotates, the slider slides onto the rail. It slides relative to the other.

[0007] Therefore, when the pair of swing arms are rotated in opposite directions from a straight line and brought closer together, the pallet comes off the lifting platform and
The pallet is moved horizontally to the right or left side of the lifting platform, and the pallet is fed into the storage shelf. Conversely, if the pair of swing arms are brought close to each other and then rotated in opposite directions and placed in a straight line, the pallet that has come off the platform and moved to the right or left side of the platform will be horizontal. It is pulled back and placed so that it overlaps the elevator platform.

The configuration will be explained with reference to FIGS. 9, 11, and 12.

The pallet 81 has a pair of aggregates 82 at its widthwise center, and strip-like rails 83 are horizontally fixed to the lower surfaces of the aggregates. These rails 83 are provided over the entire length of the pallet 81 in the longitudinal direction. Furthermore, the pallet 81 has two front wheel support parts 84 and two rear wheel support parts 85 that receive the wheels of the automobile S when it is placed on the predetermined position. These rear wheel support parts 85 are formed longer than the front wheel support parts 84, and these support parts 84, 85 are formed by providing a plurality of upwardly standing iron plates at intervals. The interval between the iron plates of each of the supporting parts 84 and 85 is equal to the interval between the grooves of the storage shelf 2, so that the comb teeth between the grooves of the storage shelf 2 can relatively enter and exit the gap between the adjacent iron plates. It has become. The delivery device 17 of this embodiment includes a turntable mechanism 91 and a swing arm mechanism 92.

As shown in FIGS. 3 and 8, the turntable mechanism 91 includes three rotatable support rollers 93 fixed to the top surface of the lifting table 14 at 90° intervals, and three rotatable support rollers 93 fixed to the top surface of the lifting table 14. The drive motor 95 includes a drive motor 95 with a drive gear 94, and a turntable 96 supported by the support rollers 93 and the drive gear 94. The turntable 96 has a ring-shaped gear 97 on its lower surface.
7 is meshed with the drive gear 94. Therefore, when the drive motor 95 is operated, the gears 94, 9
7, the turntable 96 is rotated while rolling on the plurality of support rollers 93, and the direction of the pallet 81 can be arbitrarily changed by this rotation.

The swing arm mechanism 92 includes a drive section 101 attached to a turntable 96. As shown in FIG. 10, this drive unit 101 connects a first worm deceleration mechanism 103 to the output shaft of a motor 102 capable of forward and reverse rotation, and connects a worm 104 of this mechanism 103 to a second worm reduction mechanism via a shaft coupling 105. The worm reduction mechanism 106 is connected to each other. The worms 104, 107 of the first and second worm deceleration mechanisms 103, 106 have teeth twisted in opposite directions. Therefore, the output shaft (worm wheel shaft) 1 of each reduction mechanism 103, 106
08 and 109 are turned in opposite directions at the same time and at the same speed.

Each of the output shafts 108 and 109 faces upward, and one end portion of a pair of swing arms 110 positioned on the tarten bull 96 is connected to each of the output shafts 108 and 109 separately. On the upper surface of the turntable 96, each output shaft 108, 1
A semicircular arm support 111 that supports the middle of the swing arm 110 extending in the radial direction of the swing arm 110 from below is attached to face each arm 110. The swing arm 110 rotates horizontally while sliding on the upper surface of the arm support 111. A pivot 112 is attached to the tip of each swing arm 110, as shown in FIGS. 6 and 7.
A slider 113 is rotatably attached to this shaft 112.

The slider 113 includes two pairs of upper and lower engagement rollers 114 and 115, and an intermediate roller 116 disposed between them. This slider 113 is engaged with the rail 83 of the pallet 81. Specifically, as shown in FIG. 7, the upper and lower engaging rollers 114 and 115 are
A pair of rails 83 sandwiching the rail 83 from above and below.
An intermediate roller 116 that is rotatably connected to a pair of rails 83 and rotatable about a pivot shaft 112 is connected to a pair of rails 83.
It is located in between and is in rolling contact with the end surfaces of these rails 83. As described above, the pair of swing arms 110 supports the pallet 81 from below.

The swing arm mechanism 92 simultaneously reversely rotates the output shafts 108 and 109 of each of the worm reduction mechanisms 103 and 106 by operating its motor 102, so that the pair of swing arms 1 as shown in FIG.
10 can be simultaneously rotated and displaced from the position shown by the solid line to the position shown by the two-dot chain line. At this time, the slider 113 of the swing arm 110 slides on the rail 83 of the pallet 81, and at this time, the slider 113 rotates around the pivot 112, so its direction is determined by the direction of the swing arm 110. can be changed appropriately according to changes in Therefore, the slider 113 does not get caught between the rails 83 and become locked. Swing arm 11 like this
As the slider 113 rotates, the slider 113 at the tip of the slider
1, the pallet 81 supported by the pair of swing arms 110 moves away from the center reference position X in FIG. It is horizontally moved to position Y or lower storage position Z.

When the pallet 81 is moved to the storage position Y, the pallet 81 is stored in the storage shelf 2 on the left side in FIG. It is stored in storage shelf 2. By this storage, the comb teeth of the storage shelf 2 are inserted between the iron plates of the front wheel support part 84 and between the iron plates of the rear wheel support part 85 of the pallet 81, respectively. Therefore, after this, the elevator platform 1
By lowering the delivery device 17 together with the pallet 81 , the pallet 81 is moved to the lower side of the storage shelf 2 , and the automobile S on the pallet 81 is placed on the storage shelf 2 . Naturally, by performing the reverse operation of the above storage operation, the automobile S placed on the storage shelf 2 can be moved onto the pallet 81, and then the pallet 81 can be transferred onto the lifting platform 14.

As described above, the pallet 81 is moved horizontally across the storage shelf 2 and the lifting platform 14 by the rotation in the horizontal plane of the swing arm 110 provided in the delivery device 17, so that a plurality of moving platforms are provided. Compared to the conventional one, the pallet 81 can be moved to a predetermined position by one operation of the drive unit 101, and the processing time is short.

Further, as described above, the swing arm mechanism 92 of the delivery device 17 horizontally moves the pallet 81.
According to the configuration, since the pallet 81 is moved based on the horizontal rotation of the pair of swing arms 110, the number of parts can be greatly reduced compared to the conventional configuration in which the pallet is moved by shifting a plurality of moving tables. . therefore,
It has a simple structure and is easy to assemble and maintain.

Moreover, since the pallet 81 is sent into the storage shelf 2 by the pair of swing arms 110 as described above, the swing arm 110 supporting the pallet 81 is only inserted between the vertically opposing storage shelves 2. . Therefore, compared to the conventional configuration in which a plurality of overlapping movable platforms are inserted between the vertically opposing storage shelves 2, the height direction occupied by the delivery device 17 inserted between the vertically opposing storage shelves 2. space is small. Therefore, it is advantageous to reduce the height of this multi-story parking lot. Alternatively, it is advantageous to increase the number of cars S accommodated. This can be maintained even when the length of the pair of swing arms 11 is increased to ensure a large movement stroke of the pallet 81.

As shown in FIGS. 2 and 3, support devices 121 are attached to each of the four corners of the lifting table 14, and are operated while the lifting table 14 is positioned with respect to a desired storage shelf 2. . This device 121 is used to stabilize the lifting platform 14 so that it does not tilt during the above-mentioned delivery of the automobile S. The support device 121 has a support shaft 123 that is horizontally moved via a rack and pinion structure (not shown) operated by a motor 122 with a speed reducer. Further, the support device 121 has a movable shaft 125 that vertically passes through the mounting bracket 124, and a spring 126 that constantly pulls down the movable shaft 125. Movable axis 125
A housing 127 to which the motor 122, support shaft 123, etc. are attached is fixed to the upper end of the housing 127.

In this support device 121, the motor 12
2 to cause the support shaft 123 to protrude in the direction of the arrow in FIG. Therefore, the four corners of the lifting platform 14 can be supported by the support column 4 via the support device 121 and the receiving part 128. Therefore, since the load changes caused by the movement of the pallet 81 described above can be supported by the pillars 4, the lifting platform 14 is prevented from tilting regardless of the unbalanced load, and the vehicle S can be transferred via the pallet 81 described above. can be carried out without support. Further, when the pallet 81 is lowered via the lifting platform 14 and moved to the lower side of the storage shelf 2, movement is allowed by elastic deformation of the spring 126 in the contraction direction, and the support shaft 123 is moved to the receiving part 128.
When the support device 121 is removed from the support device 121, the spring 126 returns the support device 121 to its original state.

Next, the operation of the multi-story parking lot with the above configuration will be explained. In the standby state, the elevator platform 14 is placed at the lowest position, that is, on the lower traveling carriage 10, and is located at the entrance of the parking lot building 1. In this state, the positioning protrusions 38 and 39 and the positioning protrusions 43 and 44 are engaged with each other, and the elevating platform 14 is positioned with respect to the lower traveling vehicle 10 in the longitudinal and lateral directions. Furthermore, in this standby state, as shown in FIG. 1, the pair of swing arms 110 are arranged so as to be continuous on a straight line.

First, when the automobile S that enters from the entrance is placed on the pallet 81, the motors 24 and 36 are operated in synchronization, so that the pinion 25 rotated by the motor 24 is prevented from meshing with the upper track 9. At the same time, the pinion 37 rotated by the motor 36 changes its engagement with the lower raceway 10. As a result, the upper and lower traveling carts 11, which are connected via the fixed wire rope 13,
12 are moved synchronously to an empty shelf position. In this traveling, the vertical traveling trolley 11
rolls on the upper guide rail 7 via its wheels 22,
The lower carriage 12 rolls on the lower guide rail 8 via its wheels 33, 34.

After this, the elevating drive source 16 is operated and each movable wire rope 15 is moved in the direction of the arrow in FIG. It will be stopped at the desired position. in this case,
The lifting platform 14 is moved by sliding the fixed wire rope 13 via the slider 41. The speeds of the motors 24 and 36 are controlled so that when the carts 11 and 12 and the lifting platform 14 are started, they are soft-started, and when they are stopped, they are soft-stopped. Then, each support device 121 is operated to support the four corners of the lifting platform 14 with respect to the support column 4.

Next, since the delivery device 17 performs a feeding operation, the automobile S is carried into the vacant storage shelf 2 via the pallet 81 that is moved by the horizontal rotation of the swing arm 110. After this loading, the lifting drive source 1
6 is driven again, the elevator platform 14 is lowered a little, and the automobile S is transferred to the empty storage shelf 2.

Finally, the motor 102 of the delivery device 17
(in other words, the pallet 81 is returned onto the lifting platform 14 through the horizontal rotation of the swing arm 110), and the support shaft 12 of the support device 121
8 is removed from the receiving part 132 of the support column 4, the elevating drive source 16 is operated again to lower the elevating table 14 to the lowest position. Finally, the motors 24 and 36 are operated to drive the upper and lower traveling carts 11 and 1 connected via the fixed wire rope 13.
2 to the entrance of parking building 1.

[0042] In addition, in order to carry out the stored automobile S, first, after running the upper and lower traveling carts 11 and 12,
The elevating table 14 is raised and positioned on the storage shelf 2 at the delivery position, and is supported on the support column 4 by the support device 121. Next, by operating the delivery device 17, the pallet 81 is sent to the lower position of the storage shelf 2 on which the automobile to be taken out is placed. Then, by slightly raising the elevator platform 14, the vehicle S mounted thereon is released from the storage shelf 2, and the vehicle S is supported on the pallet 81. Thereafter, by retracting the swing arm 110 of the transfer device 17, the car S is returned to the lifting platform 14 via the pallet 81, the supporting device 121 is returned, and the lifting platform 14 is moved to the lowest position. lower it. Next, after returning the upper and lower traveling carts 11 and 12 to the entrance of the parking lot building 1, the turntable 96 is rotated half a turn. Finally, the driver gets into the car S and leaves the parking lot facing forward from the entrance of the parking building 1.

Rails 142 extending in the length direction are attached to the upper surfaces of these arms 110, respectively. As shown in FIG. 18, each rail 142 is provided from the middle to the tip of the swing arm 110, and has grooves 143 on both sides to prevent it from coming off, as shown in FIG. 21.

The pallet 81 has an elongated shape that matches the shape of the bicycle T, and has fork-shaped support plates arranged on its top surface to sandwich and support the front and rear wheels of the bicycle T from both sides, as shown in FIG. Front wheel support section 8 provided with
4 and a rear wheel support portion 85. This palette 8
As shown in FIG. 17, there is a pair of sliders 1 on the lower surface of
45 is attached. As shown in detail in FIGS. 20 and 21, the slider 145 is a fixed shaft 14 that has a mounting plate 146 at its upper end that is bolted to the lower surface of the pallet 81.
A rotating member 149 is pivotally supported on the rotating member 7 via a bearing 148, and a slider 150 is fixed to the rotating member 149 with a screw 151. The slider 150 is the rail 1
42 so as to straddle this, and has a sliding protrusion 152 that engages with the groove 143. The operation of feeding the pallet 81 by the delivery device 141 having the above configuration will be explained.

When the drive unit 101 is operated, the pair of output shafts 108 and 109 provided in the drive unit 101 are simultaneously rotated in opposite directions at the same speed. Therefore,
A pair of swing arms 110, each of which has one end connected to the output shafts 108 and 109, can be rotated horizontally without changing its height position. As a result, the pallet 81 supported on the swing arm 110 via the slider 145 is moved from the elevator platform 14 as the pair of swing arms 110 are rotated in a direction toward each other from the state in which they are arranged in a straight line. Moved horizontally away from directly above and to the right or left of it. Even at this time, the mutual positional relationship between the pair of sliders 145 does not change, so the slider 145 slides the rail 142 from the middle part of the swing arm 110 toward the tip shown in FIG. At the same time, the slider 150 is connected to the swing arm 11.
It rotates around the fixed shaft 147 according to the rotation angle of 0. Therefore, the pallet 81 is horizontally moved as shown by the two-dot chain line in FIG. 17 and sent to the storage shelf 2.

Further, the pulling back of the pallet 81 by the delivery device 141 is performed by the motor 102 provided in the drive section 101.
This is done by reversing the rotation of the feed. At this time, the slider 145 slides on the rail 142 from the tip of the swing arm 110 toward the middle while rotating the slider 150. Thereby,
When the swing arm 110 is returned from the position shown by the two-dot chain line in FIG. 16 to the position shown in a straight line shown by the dotted line in the figure, the pallet 81 is simultaneously returned directly above the lifting platform 14. Therefore, the delivery device 14 of this embodiment
1, the intended purpose of the present invention can also be achieved.

The present invention is not limited to the above-described embodiments, and the specific structure, shape, position, material, etc. of each drive section, swing arm, rail, slider, etc. Of course, it can be implemented with various modifications.

Effects of the Invention As detailed above, according to the delivery device for a three-dimensional storage of the present invention, a rail and a slider that slides on a pair of swing arms that horizontally rotate in opposite directions are provided. The pallet is supported through the swing arms, and the pallet is moved between the lifting platform and the storage shelf by the rotation of the pair of swing arms, so the number of parts is small and the configuration is simple, and the pallet feeding process is simplified. At the same time, since this delivery device occupies less space between the storage shelves of the vertically facing three-dimensional storage, the height of the three-dimensional storage can be reduced.
