Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for storing vehicles, luggage, etc. in a three-dimensional stack indoors or outdoors.

0002

[Prior Art] Various types of devices for storing vehicles and the like three-dimensionally have been known in the past. Three-dimensional storage devices can be roughly divided into self-transporting devices and mechanical devices that move up and down. There are two types: those that are self-propelled and those that are a combination of a lifting machine and those that are a combination of a self-propelled cage and a lifting machine.The mechanical ones include those that have a cage suspended on a chain and stored by circulating it in the vertical direction;
Alternatively, systems that raise and lower a cage like an elevator and store vehicles automatically or by self-propulsion in a large number of storage stages provided in the vertical direction, or systems that raise and lower pallets up and down have been put into practical use.

0003

[Problems to be Solved by the Invention] By the way, in the case of the type in which the cage is suspended from a chain and circulated in the vertical direction, and the type in which the cage is circulated in the vertical direction, and in the case of the type using the elevator system with a large number of storage stages, the buildings covering these devices are made to be high-rise. Although this has the advantage of storing a large number of vehicles in a small space, it has the disadvantage of significantly increasing construction costs. On the other hand, if the pallet is of the type that moves up and down, vehicles stored in the upper tier can only be taken out after the vehicles stored in the lower tier have been taken out. There is a problem in that a place for the vehicle to retreat is required, and it takes time and effort to enter and exit the vehicle.

[0004] In order to solve the above problems, it is conceivable to store vehicles or goods in a manner that circulates between two upper and lower stages. , lift means are required to raise and lower at both ends. In conventional technology, both means are generally configured to be driven separately, and for this purpose, it is necessary to provide a transfer means for transferring the cart to both means, and the structure and drive of these means is required. As control devices and the like become more complex, accuracy is required.

In contrast to the above-mentioned type of storage that circulates between the upper and lower stages, the present invention is constructed by integrating the conveyor means and the lift means in a series, thereby simplifying the structure and maintaining a stable state. It was developed with the purpose of being able to be stored.

[0006]

[Means for Solving the Problems] The solution according to the present invention is to connect a plurality of wheeled carts along each rail laid in the upper and lower stages with an endless drive chain connected to one end of each cart. The carts are arranged in a row so that they can run on each rail and move up and down between the upper and lower rails to circulate, and a sub-driving chain is provided that runs parallel to the rising running portion of the main-driving chain and rotates in opposite directions at the same speed. A wing section is provided to protrude toward the side of the end, and a grooved roller that engages with the wing section is provided on the auxiliary drive chain to provide support to the main drive chain when the bogie moves up and down the rising running section of the main drive chain. The carriage can be raised and lowered horizontally by the grooved rollers engaging and supporting the wing parts, and the part between the rising running part of the main drive chain and the auxiliary drive chain on the upper rail. It is characterized in that it includes a space through which the wheels pass, and that the upper rail is provided with a joint rail that fills the space so as to be able to swing up and down.

[0007]

[Operation] The driving chain drives in only one direction,
In addition, the auxiliary chain rotates in the opposite direction to the main chain and is driven at the same speed as the main chain, and since the main chain is connected to one end of the cart, it rises together with the main chain when the main chain rises and runs. In this case, the wing portion of the truck rises while being supported by the grooved rollers of the auxiliary chain, and since the main chain and the auxiliary chain are driven at the same speed, the truck rises horizontally. When it rises in this way, the joint rail is pushed up by the wheels near the wing, and the wheels engage with the upper rail through the space opened by the rise, and at the same time, the other wheels also engage with the starting end of the rail. Thereafter, the rollers descend and come off the blades, and the joint rail moves back, so the carriage runs along the upper rail by the driving force of the main drive chain.

[0008]

[Embodiment] To specifically explain the present invention with reference to the storage of a vehicle, as shown in Fig. 1, it is installed in a rectangular frame 1 with a raised floor, and the vehicle is stored under the floor by self-propulsion. The interior of the frame 1 is divided into two levels, upper and lower, with rails 3 and 4 running along the length of each level.
A plurality of trolleys 5 are mounted on each of the upper and lower rails 3 and 4 so as to be able to run, and a climbing road 6 that is inclined from one longitudinal end of the frame 1 (the right side in FIG. 1) is mounted. Insert the vehicle through the insertion part and place it on the trolley 5, and at the insertion part, the trolley 5 carrying the vehicle rises while keeping it horizontal and transfers it to the upper stage, and moves along the upper rail to the other end (left side in the figure) The transition will be made sequentially. Further, the cart 5 is configured to be lowered horizontally to the lower stage at the other end and then returned to the original insertion position (on the right side in the figure),
Moreover, it is to be taken out from the insertion position. However, loading and unloading is not limited to one side, and can also be done from both ends. However, a vehicle that enters the warehouse from the left side in the figure moves directly toward the other end in the lower tier.

The structure of the truck 5 will now be explained. As shown in FIGS. 2 to 4, the support shaft 7 protrudes on both front and rear sides.
, 8 are provided with wheels 9 and 10, respectively, and the rear support shaft 8 is extended longer than the wheel 10, and on both sides of the front of the truck 5, a T-shape is provided when viewed from a plane toward the side of the truck. Wing part 1
1 is provided so as to protrude further to the side than the mounting position of the wheel 9. Specifically, the wing portion 11 includes a receiving plate 13 having a warped shape and narrowed at the bottom with a wedge-shaped cross section at the tip of a protruding piece 12 protruding from the truck 5, parallel to the longitudinal direction of the truck 5, Moreover, it is provided so as to extend from the front and rear of the projecting piece 12 so as to maintain a distance between the truck 5 and the receiving plate 13. Note that the trolley 5 can also be formed in a size that allows two vehicles to be placed side by side. Further, when the container is used as a warehouse for storing cargo, containers are placed on the trolley 5 or fixedly installed.

The means for transporting the cart 5 along the rails 3 and 4 is shown in FIG.
is stretched around main sprockets 15 arranged at at least four corners, that is, the main drive chain 14 consists of front and rear rising running sections 14a, 14c and upper and lower horizontal running sections 14b.
, 14d, and as shown in FIGS. 2 and 3, both ends of the rear support shaft 8 of the truck 5 are fixed to the main drive chain 14. Therefore, the bogie 5 on the upper and lower rails 3 and 4 is driven by the drive chain 14, but if this continues, the bogie 5 will be lifted only by the rear support shaft 8 at the rising running portions 14a and 14c of the drive chain 14. and end up in a suspended state.

Therefore, as shown in FIGS. 2, 4, and 5, a pair of left and right sub-assistants that stand up and are rotatably driven are provided so that the cart 5 can be raised and lowered while maintaining its horizontal position at each of the upright running sections of the front and rear of the main drive chain 14. A driving chain 16 is provided so as to be hooked around upper and lower sub-sprockets 17, and a grooved roller 18 that engages with a receiving plate 13 provided at the front of the truck 5 is attached to this sub-driving chain 16. Therefore, this secondary drive chain 1
6 is provided so as to correspond to the receiving plate 13 of the trolley 5, and the secondary drive chain 16 is connected to the main drive chain 14.
It is driven to rotate at the same speed but in the opposite direction. Further, as shown in FIGS. 6 and 7, the grooved rollers 18 are arranged so as to engage with the receiving plate 13 at the same time as the cart 5 that has traveled on the rails 3 and 4 moves up or down. There is.

The drive system is shown in FIG.
, 22, a second intermediate shaft 23 that rotates in the opposite direction is installed in parallel, and the first intermediate shaft 20 and the driving chain 14 are connected.
3 and the front and rear sub-driving chains 16 are connected to each other for driving.

Furthermore, when the truck 5 rises, the front and rear wheels 9, 10 of the truck 5 move off the lower rail 3 and rise.
It is necessary to reach the upper stage and engage the rail 4 again, but the rear wheel 10 can engage from the curved end surface of the upper stage rail 4, but the front wheel 9 hits the lower surface of the upper stage rail 4 and cannot engage. It turns out. To solve this,
As shown in FIGS. 8 to 14, a space 24 is provided in the middle of the upper rail 4, and the end surface 25 of the rail 4 extending from the space 24 is curved downward and extended downward. In addition, the ends of the upper rails are similarly curved and extended downward to prevent lateral vibration by rails 4a, 4b, 4c, and 4d that erect each wheel 9, 10 of the bogie 5 that rises and falls horizontally. Form it to guide you while doing so. However, if this continues, the rear wheels 10 will fall in the space 24, so a pair of left and right arms 26 are pivoted to the end of the rail 4 on the side that guides the rear wheels 10 so as to be able to swing up and down. A joint rail 2 that fits into the space 24 between the arms 26
7 is fixed. The front surface of the joint rail 27 is rounded, the rear surface is a 45-degree slope, and the front surface at the end of the rail is also a 45-degree slope, so that the joint rail 27 fits into the space 24. It is designed to prevent it from falling when it falls. Therefore, when the bogie 5 rises, the front wheels 9 are guided to the top surface of the upper rail 4 from the end thereof, while the rear wheels 10 are guided to the upper surface of the upper rail 4 as it rises, as shown in FIG.
7 is pushed up and guided onto the rail 4 from the end surface 25 exposed in the space 24. When the trolley 5 travels on the upper rail 4 in this manner, the joint rail 27 that has been pushed up is housed in the space 24 by the rear wheels 10, and the joint rail 27
7 on which the rear wheels 10 can run without any trouble. still,
The arm 26 may be configured to automatically move up and down at appropriate timing.

Next, as shown in FIG. 9, the side on which the trolley 5 descends has almost the same structure as the upward side.
Also, the same parts are indicated by the same symbols, but the arm 26 is
As shown in FIGS. 11 and 12, on the upper surface of each bent base 28 of both arms 26, a footplate 29 that protrudes toward the rail 4 is pressed by the front wheel 9. 9, and the distal end surface of the base 28 is shown in FIG.
As shown in FIG.
4 is formed in a curved state similar to the curved surface at the tip of the rail 4 when opened, and when the joint rail 27 is housed in the space 24 as shown in FIG. 9, the tip of the base 28 A portion thereof is formed to protrude upward from the rail 4. Therefore, when the truck 5 travels and the front wheel 9 reaches the tip of the rail 4, the front wheel 9 presses down the protruding base 28 of the arm 26, so the arm 26 is flipped upward. Space portion 24 for lowering the rear wheel 10
The curved end face 25 is exposed. Note that when the arm 26 is configured to operate automatically, the base 28 of the arm 26 becomes unnecessary.

It has been described that the wing portion 11 of the truck 5 is formed into a T-shape, and a space is provided in front and behind the projecting piece 12, and the receiving plate 13 is formed in a warped shape. By forming the auxiliary drive chain 1 as shown in FIG.
6 rotates in the direction of the arrow, so that the grooved roller 18 can easily engage smoothly with the lower surface of the receiving plate 13. Furthermore, when the truck 5 ascends and descends, the front wheels 9 follow the upright rails 4b, 4d, so the projecting pieces 12 of the wing portions 11 protrude so as not to touch the upright rails 4b, 4d. It is necessary to form it so that it does not touch the upper rail 4 when it rises and engages with the upper rail 3 and when it descends. As one means for this, as shown in FIG. 15 and below, the width a of the protruding piece 12 is set to
The dimensions are slightly narrower. However, its dimensions are thin and the wing part 1
If there is a possibility that the strength of the protrusion 12 may be weakened, the width of the protrusion 12 can be increased by providing two front wheels 9 at the front and the rear, as shown in FIG. 18, to improve its strength. It is.

With the above structure, the trolley 5 is stopped and placed at the entrance when entering the warehouse, and after entering the warehouse, the main drive and auxiliary drive chains 14 and 16 are driven simultaneously, but the trolley 5 is moved when the main drive chain 14 starts running. Located directly below part 14a,
Since the grooved rollers 18 of the auxiliary drive chain 16 are already engaged with the receiving plate 13 of the wing section 11 of the truck 5 as shown in FIG. 6, the truck 5 is moved as shown in FIG. Keep level and rise. When the rear wheel 10 rises in this way and reaches the upper rail 4, the rear wheel 10 reaches the upper rail 4.
At the same time, the front wheel 9 raises the joint rail 27 and engages with the upper rail 4 as shown in FIG. In addition, as the truck 5 continues to run on the upper rail 4, the rear wheels 1
0, the vehicle runs by stepping on the joint rail 27. Next, when the trolley 5 descends, the front wheels 9 press against the tread 29 and move up the joint rail 27 as shown in FIG. On the other hand, at that point, the grooved rollers 18 of the auxiliary drive chain 16 are engaged with the wing portions 11, so the bogie 5 descends horizontally in the same way as when rising, and is not engaged with the lower rail 3. When the grooved roller 18
Since it is detached from the wing section 11, it runs toward the inlet section by the main drive chain 14.

[Effects of the Invention] According to the storage device for vehicles etc. according to the present invention, (a) it is not installed so as to extend high above the ground;
It is installed so that it extends horizontally on the ground, and the construction of the frame and the structure that covers the outside is easy and inexpensive. Moreover, since it is possible to enter and exit from both ends of the storage device, it is possible to significantly shorten the time required for unloading. (b) Since each bogie is configured to be mounted on the upper and lower rails and run by a main drive chain, unless the bogie is moved up and down, the weight of the bogie on the chain and the vehicles placed on it will cause it to fall. No directional load is applied, increasing safety. (c) To raise and lower the cart, a main drive chain is connected to a part of the cart, and a grooved roller provided on the auxiliary drive chain parallel to the rising and running part of the chain is protruded from the front of the cart. Since the trolley is engaged with the raised and lowered wings to raise and lower the truck, there is no need to switch the drive systems separately for the horizontal traveling section and the rising section, and the lifting and lowering operations can be performed smoothly. Of course, there is no risk of malfunction, and the structure is simplified. (d) Furthermore, by rotating the main chain and the sub-driving chain in opposite directions at the same speed, the cart can be raised and lowered horizontally, making it easy to control the rotation of both chains and preventing malfunctions. You will be able to go up and down safely at all times.
