Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bicycle storage device that can three-dimensionally store a large number of bicycles and allow efficient loading and unloading.

[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 aims to solve]

By the way, the method of hoisting 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, this invention provides a pair of rails with a U-shaped cross section on both sides of the upper surface of a lifting platform that moves up and down by a lifting mechanism, and outside the lifting space in which this lifting platform moves up and down. Bicycle storage spaces with multiple upper and lower levels are arranged in the extending direction of the rails, and on both sides of the lower part of each bicycle storage space there is a lifting platform with equal spacing and the same cross-sectional shape as the rails of the lifting platform, and stops at the same height level. A pair of rails extending from the rails is provided, a bicycle storage pallet is placed on the pair of rails in each of the bicycle storage spaces, and the rails are placed on the elevating platform. A self-propelled pallet carrier is provided that is supported between the grooves and can freely move between the lifting platform and the bicycle storage space at the same height level along the rails of both. It is configured to be vertically telescopic and equipped with a plurality of pallet lifting machines that lift the bicycle mounting pallet and float it off the rail.

[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, stop the lifting platform at the same height as the storage space from which you want to remove the bicycle, move the transport vehicle from the elevator platform into the storage space, and when the transport vehicle lifts the pallet, it will move onto the elevator platform. Returning to , the lifting platform descends to the lower take-out zone of the lifting space, and the bicycles on the pallet are artificially taken out 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.

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 volume that has a planar size that accommodates the pallet 6 and a vertical height that allows the upright bicycle A to be accommodated together with the pallet 6.
A pair of rails 18 are laid with the same width as the rails 11 of the lifting platform 3.

The elevating table 3 uses the elevating mechanism 2 to move its rails 11 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 contracted, it is separated from the pallet 6, placed on the rail 11 or 18 and released, and the pallet 6 in the storage space 5 is moved. The conveyor truck 12 can freely enter directly below.

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.

Furthermore, in the case of FIG. 1, two rows of storage spaces 5 were provided on each side of the elevating space 4.
The number of inner/outside and upper/lower parallels can be freely selected according to the space, and a plurality of sets of storage spaces 5 and lifting spaces 4 may be arranged.

The first example of this invention has the above-mentioned configuration, and next, how to put in and take out a bicycle will be explained.

Retrieving the bicycle Prepare pallets 6 one less than the total number of storage spaces 5, and place the bicycle A on the pallet 6.
are accommodated in each storage space 5 and supported on rails 18.

When the storage space is full, the retrieval 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 lift the pallet 6 with the lifting machine 17. 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.

On the other hand, 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 impede 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 the second example shown in FIG. 6, the elevating platform 3 has two stages, upper and lower, each equipped with a transport cart 12. The upper elevating platform 3a is used exclusively for loading and unloading bicycles, and the lower elevating platform 3b is used for returning empty pallets. It is designed to be used exclusively 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 unloaded in parallel while loading and unloading the bicycle A, reducing the loss time of loading and unloading operations, and reducing the work load. Improves efficiency.

〔effect〕

As described above, according to the present invention, bicycles can be loaded and unloaded in units of pallets, and when storing bicycles of the same model, such as rental bicycles, loading and unloading operations can be carried out efficiently.

In addition, since the pallets are taken out from the storage space using the carrier on the lifting platform, loading and unloading of pallets can be done only by controlling the carrier, which simplifies the mechanism.
Easy remote control.

Furthermore, the number of storage spaces can be freely selected according to the installation conditions, etc., and it is possible to easily construct a system that accommodates the number of devices according to the user's wishes.
In addition, the movement of the bicycle pallet between the lifting platform and the bicycle storage space is carried out using a transport vehicle equipped with multiple pallet lifting machines on the top surface.
When moving the pallet, the pallet can be lifted off the rail, allowing the pallet to be moved smoothly.

Moreover, when moving a pallet, lifting it from the rail can be done by simply extending the pallet lifting machine on the transport vehicle, eliminating the need for fine vertical movements on the lifting platform, which greatly simplifies the operation of loading and unloading bicycles. Can be simplified.
