After that, when the transfer device 5 pulls the bicycle on the transfer section 1a into the loading / unloading booth 1, the door of the loading / unloading booth 1 is closed, and the lifting / lowering body 4a on which the bicycle is loaded is located at the height of the relay device 7 in the underground portion. Descend to When the bicycle is lowered to the height of the relay device 7, the transfer device 5 delivers the bicycle on the lifting body 4 a to the relay device 7.

  Next, the relay device 7 to which the bicycle has been handed turns in a horizontal plane. When the bicycle rotates a predetermined angle in the horizontal plane, the relay device 7 stops rotating.

  The stacker crane 3 as a transport device moves near the relay device 7 so that the bicycle can be transferred to and from the relay device 7. The transfer device for transfer device (hereinafter simply referred to as transfer device 8) of the stacker crane 3 receives the bicycle from the relay device 7. When the bicycle is received, the stacker crane 3 transports the bicycle to the target bicycle storage portion 2a, and delivers the bicycle to the target bicycle storage portion 2a by the transfer device 8. This completes the storage of the bicycle.

  When leaving the bicycle, the reverse operation is performed. The loading / unloading booth 1, the lifting device 4, the relay device 7 and the stacker crane 3 are controlled by a control device provided in a monitoring room or the like (not shown).

  The structure of each part of the mechanical bicycle parking facility is as follows. The loading / unloading booth 1 is a box-shaped building, and has a door through which the transfer device 5 can appear and retract. There are various shapes and structures in the loading / unloading booth 1. For example, a door or window may be embedded in an extruded molded plate to produce the whole as a building, or a steel plate wall and ceiling may be integrated to improve the design. In any case, since the underground bicycle parking facility is constructed in front of a station in the city, it is required to have a good appearance and compactness as well as safety.

  In the basement, an underground portion 9 made of a huge rectangular parallelepiped concrete frame is constructed. The underground part 9 may be constructed from on-site concrete like a normal building, or may be constructed from assembled precast concrete. A plurality of pillars 9a are arranged at predetermined intervals in the basement.

  In the basement 9, a storage shelf 2 having a plurality of bicycle storage portions 2a in the vertical direction and a plurality of rows in the horizontal direction is arranged. The storage shelf 2 is arranged avoiding the pillar 9a.

  As shown in FIG. 2, the storage shelf 2 includes a structure including columns 11 extending in the vertical direction and beams 12 passed between the columns 11. Each bicycle storage portion 2a includes a V-shaped shelf member 2a1 into which a bicycle wheel fits, a rear wheel holding portion 2a2 including a pair of leaf springs sandwiching the lower portion of the bicycle rear wheel, and a stand guide for guiding a bicycle stand. 2a3. The bicycle is stored in the bicycle storage portion 2a from the rear wheel side. The bicycle stored in the bicycle storage part 2a is self-supported by the rear wheel holding part 2a2.

  3 and 4 show vertical sectional views of the underground portion 9. FIG. 3 shows a front view of the lifting device 4, and FIG. 4 shows a side view of the lifting device 4. As shown in FIG. 3, in front of the door 1b of the loading / unloading booth 1, a delivery unit 1a on which a user sets a bicycle is provided. A V-shaped groove into which a bicycle wheel fits is formed in the delivery part 1a. A recess 1a1 is provided in a portion of the V-shaped groove corresponding to the rear wheel of the bicycle. The recess 1a1 is provided with a rear wheel holding portion (not shown) for holding the bicycle in a self-supporting state. When the user fits the bicycle into the V-shaped groove and fits the rear wheel of the bicycle into the recess, the rear wheel holding portion causes the bicycle to stand on its own. The periphery of the delivery part 1a is surrounded by a fence 1a2 for safety.

  The loading / unloading booth 1 is provided with a lifting / lowering device 4 that lowers the bicycle set in the delivery unit 1a to the relay device 7. The elevating device 4 includes a support column 4c erected from the basement floor, a pair of left and right rails 4b that are attached to the support column 4c, and that can be moved up and down along the rails 4b. A belt 4d that is suspended and a servo motor 4e that raises and lowers the belt 4d are provided. A counterweight 4f is suspended from the other end of the belt 4d. A pulley 4g is provided on the belt 4d and provided at the upper end of the support column 4c. When the servo motor 4e rotates the pulley 4g, the elevating body 4a suspended from the belt 4d moves up and down. The elevating body 4a reciprocates between the ground part and the relay device 7. The upper end of the column 4 c protrudes above the ground, and the upper end of the column 4 c is covered with the loading / unloading booth 1.

  The lifting / lowering body 4a is provided with a transfer device 5 that grips the front wheel of the bicycle and draws the bicycle from the delivery portion 1a onto the lifting / lowering body 4a. The transfer device 5 is mounted on an elevating body and has a V-shaped shelf member 5a for guiding a bicycle, a pair of plate-like holders 5b for gripping the axle of the front wheel of the bicycle from the left and right directions, and the holder 5b as a shelf member 5a. And a drive mechanism 5c that slides along The pair of holders 5b is narrowed or opened by the holder driving mechanism. The pair of holders 5b are connected to an endless belt 5c2 that is stretched between pulleys 5c1. When the pulley 5c1 is rotationally driven by a servo motor (not shown), the holder 5b slides along the shelf member 5a as the belt 5c2 circulates. The holder 5b may hold the front wheel of the bicycle, not the axle of the front wheel of the bicycle.

  When the bicycle is stored, the elevating body 4a rises to the upper end. When the user sets a bicycle in the delivery unit 1a, the door of the loading / unloading booth 1 opens, and the transfer device 5 of the lifting device 4 moves toward the delivery unit 1a. When the holder 5b of the transfer device 5 grips the axle of the front wheel of the bicycle, the transfer device 5 pulls the bicycle onto the lifting body 4a. Since the transfer device 5 still holds the front wheel of the bicycle, the bicycle stands on the elevating body 4a. The lifting device 4 lowers the lifting body 4 a to the height of the relay device 7.

  Note that various structures can be employed for the lifting device 4 as described above. For example, without providing a counterweight, the elevating body 4a may be moved up and down by a toothed belt and a pulley, a winch for winding a wire rope may be used, or the elevating body 4a may be moved by a linear motor or a feed screw mechanism. You may raise and lower.

  The relay device 7 is rotatably attached to an upper end portion of a support column 18 standing from a floor surface in the basement. The height of the relay device 7 corresponds to the height of the uppermost stage of the bicycle storage part 2a, in this embodiment, the height of the fourth stage. The relay device 7 includes a V-shaped shelf member 7a extending in the horizontal direction, a turning mechanism 7b for turning the shelf member 7a in a horizontal plane, and a servo motor 7c for driving the turning mechanism 7b. The shelf member 7a is rotatably attached to the upper end portion of the column 18 via a bearing. The turning mechanism 7b includes a spur gear, a worm gear, and the like. When the servo motor 7c drives the turning mechanism 7b, the shelf member 7a turns in the horizontal plane. Similarly to the storage shelf 2, the shelf member 7a of the relay device 7 includes a rear wheel holding portion 7a1 including a pair of leaf springs that sandwich the rear wheel of the bicycle, and a stand guide 7a2 that guides the bicycle stand. The rear wheel holding portion 7a1 sandwiches the rear wheel of the bicycle so that the bicycle is self-supporting on the shelf member 7a.

  When the elevating device 4 lowers the elevating body 4a carrying the bicycle to the height of the relay device 7, the shelf member 7a of the relay device 7 turns to face the elevating body 4a. When the shelf member 7a of the relay device 7 and the shelf member 7a of the lifting body 4a are aligned, the transfer device 5 of the lifting device 4 passes the bicycle from the rear wheel side to the shelf member 7a of the relay device 7. When the bicycle is transferred to the relay device 7, the transfer device 5 releases the clamp by the holder 5b and returns to the original lifting body 4a. After receiving the bicycle, the relay device 7 turns in a horizontal plane so as to face the stacker crane 3. Since the bicycle is held by the rear wheel holding portion 7a1, the bicycle will not fall even if the relay device 7 turns.

  Next, the structure of the stacker crane 3 will be described. As shown in FIG. 1, upper and lower rails 14 a and 14 b extending along the storage shelf 2 are provided on the floor and ceiling of the underground frame. In this embodiment, one upper rail 14a is provided on the ceiling, and a pair of lower rails 14b parallel to the floor surface is provided. The stacker crane 3 travels between the rails 14a and 14b.

  FIG. 5 shows a schematic diagram of the stacker crane 3. The stacker crane 3 includes a carriage 3a that travels on the lower rail 14b, a mast 3b that stands vertically from the carriage 3a, an elevating body 3c that moves up and down along the mast 3b, and a transfer device that is provided on the elevating body 3c. 5 and a turning mechanism 3e for turning the transfer device 5 in a horizontal plane. The carriage 3a has four wheels 3a1 that travel on a pair of left and right lower rails 14b. The wheel 3a1 is rotationally driven by a servo motor (not shown).

  As shown in FIG. 4, a roller 3b1 that sandwiches the upper rail 14a is provided at the upper end of the mast 3b. The upper end of the mast 3b is guided by the upper rail 14a. A rail 13 extending in the vertical direction is attached to the mast 3b. The elevating body 3 c moves up and down along the rail 13. The elevating body 3 c is suspended from one end of the belt 14. A counterweight 15 is suspended from the other end of the belt 14. The belt 14 is hung on a pulley 16 provided at the upper end of the mast 3b. When the pulley 16 is rotated by the servo motor 17, the elevating body 3c moves up and down along the mast 3b.

  A transfer device 5 is attached to the lift 3c so as to be able to turn in a horizontal plane via a turning mechanism 3e (see FIG. 5). Since the structure of the transfer device 5 is the same as the transfer device of the lifting device 4 described above, the same reference numerals are given and the description thereof is omitted. The turning mechanism 3e that turns the transfer device 5 includes gears such as a spur gear and a worm gear, and a servo motor 3e1 that rotationally drives the gear (see FIG. 5). When the servo motor is driven, the transfer device 5 turns in a horizontal plane. The stacker crane 3 controls a servo motor for running the carriage 3a, a servo motor for raising and lowering the lifting body 3c, a servo motor for operating the transfer device 5, and a servo motor for operating the turning mechanism 3e. A control panel 19 is provided.

  As shown in FIG. 1, the frame 3a2 of the carriage 3a of the stacker crane 3 is formed in a frame shape. When the elevating body 3c is lowered to the lowest end, the elevating body 3c enters the frame 3a2 (see FIG. 4). Since the bicycle placed on the stacker crane 3 can be lowered to near the floor surface, the storage shelf 2 can be arranged close to the floor surface, and the number of stages of the storage shelf 2 can be increased.

  6 and 7 show plan views of the underground part. FIG. 6 shows the positions of the three loading / unloading booths 1. The rightmost entry / exit booth 1 is tilted due to ground conditions. Below the loading / unloading booth 1, an elevating device 4 for lowering the bicycle is disposed.

  As shown in FIG. 6, the relay device 7 is disposed adjacent to the lifting device 4. The stacker crane 3 can move to the vicinity of the lifting device 4 and the relay device 7. Since the elevating device 4 is provided with a support column, the stacker crane 3 cannot move to the elevating device 4. For this reason, one end of the rail 14 b of the stacker crane 3 is stopped before the lifting device 4.

  The number of lanes of the stacker crane 3 corresponds to the number of loading / unloading booths 1, and three lanes are shown in FIG. Storage shelves 2 having multiple stages and multiple rows of bicycle storage portions 2a are arranged on the left and right sides of the lane. The pitch in the horizontal direction of the lane is set constant.

  When the bicycle is transferred from the lifting device 4 to the relay device 7, the relay device 7 faces the lifting device 4, and the transfer device 5 of the lifting device 4 and the shelf member 7a of the relay device 7 are in a straight line. As described above, the transfer device 5 of the elevating device 4 passes the bicycle to the relay device 7 while holding the front wheel of the bicycle. In the relay device 7, the rear wheel of the bicycle is held by the rear wheel holding portion 7a1. When the bicycle is received from the elevating device 4, the relay device 7 turns 40 to 50 degrees and faces the stacker crane 3 (indicated by a one-dot chain line 7a-1 in FIG. 6). As described above, the stacker crane 3 cannot move to the lifting device 4. Rotating the relay device 7 by 40 to 50 degrees can most reduce the space while avoiding interference between the lifting device 4 and the stacker crane 3.

  When the shelf member 7a of the relay device 7 and the transfer device 5 of the stacker crane 3 are aligned, the transfer device 5 of the stacker crane 3 slides toward the relay device 7, and the bicycle front wheel on the relay device 7 is moved. grab. Then, the bicycle is drawn onto the lifting body 3 c of the stacker crane 3. The stacker crane 3 swivels the transfer device 5 in the horizontal plane so as to face the storage shelf 2 (indicated by a one-dot chain line 5-1 in FIG. 6), and moves horizontally to the position of the target bicycle storage unit 2a. The elevating body is moved up and down to the height of the target bicycle storage portion 2a. When the transfer device 5 is moved to the front of the target bicycle storage portion 2a, the transfer device 5 delivers the bicycle to the target storage shelf 2. As described above, automatic storage of bicycles becomes possible. Bicycle exit operation is the reverse of the above entry operation.

  According to the present embodiment, since the bicycle is transferred directly between the elevating device 4 and the stacker crane 3 via the relay device 7 that can turn in the horizontal plane, The degree of freedom of the layout of the stacker crane 3 and the storage shelf 2 with respect to the delivery booth 1 is expanded. For example, as shown in FIG. 7, even if the loading / unloading booth 1 and the stacker crane 3 are arranged apart from each other in a plane, it is possible to deliver a bicycle by arranging the relay device 7 between them. .

  Since the transfer device 5 is provided in the lifting device 4 and the transfer device 5 is provided in the stacker crane 3, it is not necessary to provide the transfer device 5 in the relay device 7. The same position (the front wheel of the bicycle in the above embodiment) can be grasped.

  It is necessary to provide the stacker crane 3 between each stage of the storage shelf 2 by enabling the transfer device 5 of the stacker crane 3 having a turning function to move up and down according to the height of the bicycle storage portion 2a of the storage shelf 2. This eliminates the need for a space for the stacker crane 3 between the stages of the storage shelf 2. For this reason, the number of stages of the storage shelf 2 can be increased.

  In addition, this invention is not limited to the said embodiment, In the range which does not change the summary of this invention, it can change variously.

  For example, in the above embodiment, the entry / exit entrance is provided in the ground part and the storage shelf is provided in the basement part. However, the present invention is not limited to this, and the floor of the entry / exit entrance and the storage shelf are different. Just do it. For example, the roof of a building may be used as a bicycle storage space. In this case, an entrance / exit is provided on the first floor, and the bicycle is raised from the first floor to the roof by a lifting device, via a rooftop relay device and a stacker crane. After that, the bicycle is stored in a storage shelf on the roof.

  In the above-described embodiment, a loading / unloading port for loading and unloading bicycles is provided, but the loading / unloading port may be separated.

  In the said embodiment, although one stacker crane is provided with respect to one loading / unloading port, you may provide one stacker crane with respect to two loading / unloading ports arrange | positioned on the lane of a stacker crane.

  In the above embodiment, a bicycle is passed from one relay device to one stacker crane, but the bicycle may be distributed from one relay device to one of two or more stacker cranes.

  In the above embodiment, only one shelf member of the relay device is installed, but a plurality of shelf members of the relay device may be provided. For example, the shelf member of the relay device may be provided at the height of the third stage or the second stage of the storage shelf. When a plurality of shelf members are provided in the relay device, the buffer function becomes higher.
