[Conventional technology]

When it comes to storing bicycles, flat storage is extremely inefficient. For example, when renting a bicycle that requires storing a large number of bicycles, a vast amount of storage space is required. Effective utilization is strongly desired.

As a conventional three-dimensional storage device for bicycles, for example, as shown in Japanese Patent Application Laid-Open No. 59-44470, a device was proposed in which the handles of the bicycles are lifted up using a lift device, and each bicycle is stored one by one. There is.

[Problem that the invention seeks to solve]

By the way, the method of lifting and transporting bicycles one by one is extremely inefficient and takes time to take in and take out.Especially when storing bicycles of the same structure, such as rental bicycles, it is not efficient to take in and out one by one. The problem is that it's bad.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a bicycle storage device that allows efficient use of space and allows for efficient loading and unloading operations.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a lifting platform that moves up and down by a lifting mechanism and is provided with a pair of rails having a U-shaped cross section on both sides of the upper surface, and a lifting space in which the lifting platform moves up and down. A plurality of upper and lower bicycle storage spaces arranged in the extending direction of the rails on the outside of the bicycle storage space, and provided on both sides of the lower part of the bicycle storage space, having equal spacing and the same cross-sectional shape as the rails of the lifting platform, and having the same height. a pair of rails arranged in an extended manner with respect to the rails of the lifting platform stopped at a level position; a bicycle storage pallet placed between the pair of rails in each of the bicycle storage spaces; A self-propelled pallet carrier disposed on the elevating platform supported between the grooves of the rails and movable along the rails between the elevating platform and a bicycle storage space at the same height level; , a plurality of pallet lifting machines installed on the pallet transport vehicle so as to be able to extend and retract vertically and lift the bicycle-mounted pallet and float it from the rail; A plurality of bicycle storage spaces are arranged horizontally, and the rails on both sides of the lower part of each bicycle storage space are arranged continuously across the horizontally arranged bicycle storage spaces.

[Effect]

Bicycle mounting pallets are arranged in all but one of the storage spaces, and a plurality of bicycles are mounted and stored on each pallet.

To take out a bicycle, the lifting platform is stopped at the same height as the storage space from which the bicycle is to be taken out, and the carrier is moved from the lifting platform into the storage space. Multiple storage spaces are lined up on the same plane, but the transport cart can be moved to any position.
When the carrier picks up the pallet in a predetermined storage space, it returns to the lifting platform, and the lifting platform descends to the lower take-out zone of the lifting space, and the bicycles on the pallet are artificially removed to the outside.

Empty pallets are sent into the empty storage space by a transport cart, and the lifting platform on which the transport cart returns rises for the next take-out. When the bicycle is taken out in the same manner as above, the empty pallets are removed from the previous take-out. By gradually feeding the empty storage space,
Bicycles in each storage space can be taken out in order.

Bicycles can also be stored by moving an empty pallet to the removal zone, placing the bicycle on the pallet, and then transporting the pallet to the previous empty storage space.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, inside the bicycle storage structure 1, there is a central lifting space 4 where a lifting platform 3 moves up and down by a lifting mechanism 2, and a plurality of upper and lower bicycle storage stages along both sides of this lifting space 4. A pallet 6 on which a bicycle A is placed is arranged in each storage space 5 except for one storage space.

As shown in Figures 3 and 4, the pallet 6 has a planar size large enough to accommodate, for example, 10 bicycles A in an upright position, and has bicycle stand-up holders 7 on the top surface and bicycle stand-up holders 7 on both sides. A side frame 8 that can be raised and lowered is attached.

As shown in FIG.
It is formed into a rectangular frame shape that is slightly larger in plan than the
Wheels 10 that hold the guide rails 9 of the structure 1 are provided at both end corners thereof, and are vertically moved up and down by an elevator-type elevating mechanism 2.

A pair of rails 11 with a U-shaped cross section extending in the direction of the storage spaces 5 on both sides are laid on the upper surface of the lifting platform 3, and a pallet carrier 1 is installed between the rails 11.
2 is placed.

The transport vehicle 12 has a plurality of wheels 14 mounted on both sides of a frame 13 that roll on rails 11, and a drive motor 15 for the wheels 14 on the frame 13;
It is formed by attaching an interlocking mechanism 16 for each wheel 14 and a plurality of pallet lifting machines 17.

Each of the storage spaces 5 is formed by a space with a planar size that accommodates the pallet 6 and a vertical height that accommodates the bicycle A standing up along with the pallet 6. A plurality of storage spaces 5 are lined up in the bicycle loading/unloading direction, and each storage space 5 has a pair of rails 18 laid on both sides of the lower part with the same width as the rails 11 of the lifting platform 3 so as to be continuous with the inner and outer independent spaces. In addition,
The number of parallel lines inside and outside the independent space may be increased or decreased depending on the installation space.

The elevating table 3 is moved by the elevating mechanism 2 to its rails 11 with respect to the upper and lower storage spaces 5 as shown in FIG.
The carriage 12 stops at the same height as the rail 18 of the storage space 5, and the carriage 12 can move freely from the elevator platform 3 toward the storage space 5 by moving along the rails 11 and 18. It's getting old.

A lifting machine 17 attached to the carrier 12 lifts the pallet 6 during expansion, and lifts the pallet 6 onto the rail 11.
Or by floating from 18, this palette 6
When the lifting machine 17 is retracted, the pallet 6 is lowered, and during the downward movement, the pallet 6 is supported by the upper surface of the rail 11 or 18 and stopped. Upper machine 17
will contract further and will separate from the bottom surface of the pallet 6. Therefore, the transport vehicle 12 can freely enter directly below the pallet 6 in the storage space 5.

In addition, rails 11 and 18 are provided on both sides of the lower surface of the pallet 6 so that the direction of conveyance of the pallet 6 is accurate.
A guide 19 circumscribing the transport vehicle 12 is fixed, and the transport vehicle 12 is equipped with power supply equipment such as a cord reel type so that the motor 15 of the transport vehicle 12 can be electrically controlled even when moving to the storage space 5. is installed.

In addition, in the case of Figures 1 and 2, the storage space 5 has two rows of independent spaces on each side of the lifting space 4, but the number of parallel spaces inside and outside and above and below can be freely selected according to the space. Additionally, a plurality of sets of these storage spaces 5 and lifting spaces 4 may be arranged.

This invention has the above-mentioned configuration, and next, how to put in and take out a bicycle will be explained.

Retrieval of bicycles The number of pallets 6 that is one less than the number of independent spaces in all storage spaces 5 is prepared, and the pallets 6 on which bicycles A are placed are accommodated in each storage space 5 and supported by being placed on the rails 18. .

When the storage space is full, take out zone 4a
Only the lowest inner storage space 5a facing the room is empty.

To take out the bicycle A in this state, move the lifting platform 3 toward the lowest storage space, move the carrier 12 to just below the pallet in the outer storage space 5b, and use the lifting machine 17 to remove the pallet 6. The bicycle A is lifted and transferred to the top of the lifting platform 3, and the bicycle A is taken out while being placed on the lifting platform 3.

The empty pallet is transported again to the storage space 5b by the carrier 12, and only the carrier 12 moves to the lifting platform 3.
Return to

Next, the elevator platform 3 is raised from the lower part to the height of the second storage space, and the pallet 6 in the storage space 5c inside the second tier is taken out onto the elevator platform 3 using the transport vehicle 12, and the elevator platform 3 is moved to the removal zone. Remove bicycle A by lowering it to 4a,
The empty pallet is stored in the bottom inner storage space 5.
Send it into a.

Raise the elevator platform 3 again to the height of the second storage space, take out the pallet 6 in the second outer storage space 5d onto the elevator platform 3 using the carrier 12, and lower the elevator platform 3 to the takeout zone 4a. Take out bicycle A.

The empty pallet 6 is returned to its original location inside the storage space 5d outside the second stage by the elevator platform 3 raised to the height of the second stage storage space and by the conveyance truck 12.

The elevating table 3 on which the transport vehicle 12 is mounted rises to the position of the third storage space, and the bicycle in this space is taken out.

In this way, pallet 6 in the outer storage space
After the bicycle is taken out, it is returned to its original storage space, making it a reciprocating movement.

In contrast, pallet 6 of the inner storage space
After the bicycle is taken out, the pallets are sequentially sent to the inner storage space one step below, so as not to interfere with the removal of the pallets in the outer storage space.

In FIG. 1, arrows drawn within each storage space are included to help understand the movement of pallets in each storage space.

Storing a Bicycle To store a bicycle in each storage space, it is necessary to sequentially move downward from the empty storage space at the top, and the pallet in the outer storage space 5 is stored until it reaches the take-out zone 4a in the same way as when taking it out. After the bicycle A is moved and loaded, it is stored by giving a reciprocating motion to return it to the original storage space.

The pallet in the inner storage space is located in extraction zone 4.
After the bicycle is taken out and loaded in the storage space a, the bicycle is stored by being sent to the inside storage space one step higher than the original storage space, and the empty pallet inside the outside storage space can be taken out.

Next, in FIG. 1 and FIG. 2, the dashed line in the same figure shows that the lifting platform 3 has two stages, upper and lower, each equipped with a transport cart 12, the upper lifting platform 3a is used exclusively for loading and unloading bicycles, and the lower lifting platform 3b is used exclusively for loading and unloading bicycles. This figure shows an example in which it is used exclusively for returning empty pallets to shorten the loading and unloading work.

A recessed portion 21 is provided in the take-out zone 4a of the lifting space 4.
is provided so that the upper elevating table 3a is at the same level as the lowest storage space when descending, and a table lifter 22 is arranged on the side floor surface of the elevating table.

When taking out the bicycle, take out the pallet from inside the storage space onto the upper elevating platform and place it in the taking out zone 4a.
After taking out the bicycle, the empty pallet is transferred onto the table lifter 22 at the raised position, and then the table lifter 22 is lowered, and the empty pallet is sent onto the lower lifting platform 3b at the lowered position.

When the lifting platform rises again to take out the next bicycle and the upper lifting platform 3a is taking out the pallet, the lower lifting platform facing the storage space one step below it moves the empty pallet into the storage space. It will be sent inside.

Furthermore, when storing the bicycle, while the transport vehicle 12 of the upper lifting platform 3a is feeding the pallet to the storage space, the lower lifting platform 3b
The transport cart is taking out empty pallets from the lower storage space.

In this way, by arranging the lifting platforms 3a and 3b in two stages, upper and lower, and arranging the table lifter 22, empty pallets can be loaded and transported in parallel while loading and unloading the bicycle A, reducing loss time during loading and unloading operations. , work efficiency is improved.
