Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a box-shaped circulation type parking device, and in particular to a box-type circulation type parking device which is designed to simplify and make the structure more compact, and to reduce noise generated when a vehicle tower carriage is moved laterally. Regarding parking devices.

In general, a box-type circulation parking system has horizontal movement rails arranged in parallel in multiple stages, vertical movement rails arranged at both ends to communicate between the rails of each stage, and rails that run along these rails. It mainly consists of a large number of vehicle tower carts (called carriers or pallets) arranged in rows so that they can be circulated freely. It is known as a facility that can accommodate

However, in this type of conventional parking device, as shown in FIG. 1, each trolley b is provided with a coupler c to connect adjacent trolleys b on the lateral movement rail a, and A rack d was formed on each trolley b for transportation, and the structure was extremely complicated. Moreover, the drive pinion e that engages with the rack d to move the carriage b laterally is
Because it is installed away from the rail f for lifting and lowering so as not to interfere with the lifting and lowering of the connector c, a tensile force acts on the pull-in side and a compressive force acts on the delivery side, with the drive pinion e as the boundary. There was a problem of large noise being generated due to collisions between the trolleys. Furthermore, in addition to the complicated structure as described above, the cart b is moved up and down via a movable rail g that is separately provided on the rail f for lifting and lowering, so it is necessary to have large vertical and horizontal dimensions. This led to an increase in the size of the device. In particular, due to the space occupied by the movable rail g, a large gap is created between the floor of the building at the vehicle entry/exit area and the end of the bogie b, so there is a movable deck, etc. between them to prevent wheels from falling off. This required a large number of parts, leading to an increase in costs.

Therefore, the present invention was devised to effectively solve the various problems mentioned above.The purpose of the present invention is to have a simple structure, to make the device more compact and to reduce costs, and to reduce the size of the trolley. An object of the present invention is to provide a box-shaped circulation parking device that can reduce noise during movement.

A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

In FIGS. 2 and 3, reference numeral 1 denotes horizontally moving rails which are long and parallel in the horizontal direction at appropriate intervals in the vertical direction, and in this embodiment are comprised of two stages, upper and lower. The lateral movement rail 1 of each stage is composed of a set of channel steels with respective grooves 2 facing inward at appropriate intervals in the vertical direction. Then, a bogie 3 for mounting a vehicle between this set of channel steel
will be handed over. That is, a flat rectangular cart 3 having sufficient space to mount a vehicle.
has a pair of left and right wheels 4 at its front and rear ends, and these wheels 4 are engaged with the grooves 2 of the lateral movement rail 1 to be supported so as to be freely movable in the longitudinal direction thereof. A large number of carts 3 are arranged in horizontal rows in the longitudinal direction of the lateral movement rail 1 with their adjacent ends butted against each other.

The trolley 3 with such a two-point support structure is a lateral movement rail 1
Although it is possible to reliably maintain the level on the upper part, it is difficult to maintain the level on the vertical movement rail 5, which will be described later, unless a movable rail is used. Therefore, auxiliary wheels 6 are provided at the front and rear ends of the truck 3 at the remaining vertices of a triangle with the pair of left and right wheels 4 as two vertices, so that the truck 3 can be held horizontally by three-point support. be. The auxiliary wheels 6 are disposed below the trolley 3 so as not to interfere with the movement of the vehicle in and out, and are supported with their axles 7 projecting outward for use in raising and lowering.

Elevating and lowering rails 5 are connected to both ends of the lateral movement rail 1 in the longitudinal direction to connect the respective stages. The elevating and lowering rails 5 are constructed by erecting channel steel at the four corners to engage and directly guide the wheels 4 disposed at the four corners of the truck 3, respectively. The grooves 2 of the lateral movement rail 1 and the grooves 8 of the vertical movement rail 5 communicate with each other so that the wheels 4 can circulate. In the embodiment, both vertically moving rails 5
One of them (the right side in FIG. 2) is made longer so that the trolley 3 can be guided to the vehicle entrance/exit part 9 formed at a high position. Auxiliary rails 10 for guiding the auxiliary wheels 6 are attached to both the rails 5 for vertical movement. Although this auxiliary rail 10 is mainly arranged in the vertical movement direction, a short traverse auxiliary rail section 11 is used to guide the auxiliary wheels 6 in the lateral movement direction when carrying out and loading the trolley 3 to and from the lateral movement rail 1 of each stage. It has integrally. The auxiliary rail 10 and the traverse auxiliary rail portion 11 are made of channel steel (H-beam steel in the illustrated example) in order to engage and guide the auxiliary wheels 6. Also,
A notch 12 is formed in a portion of the lateral movement rail 1 and the vertical movement rail 5 that are crossed by the auxiliary wheels 6 to avoid interference therebetween.

The auxiliary rail 10 is provided with a truck lifting means 13 for moving the truck 3 up and down along the lifting rail 5. As shown in FIGS. 4 and 5, this trolley lifting means 13 has an auxiliary rail 1
Sprocket 14,1 located at the upper and lower ends of 0
5, an endless chain 16 stretched between both sprockets, and hooks 17 formed at appropriate intervals around the entire circumference of this chain 16 (intervals between each stage of the lateral movement rail). It is configured so that the axle 7 of the auxiliary wheel 6 is latched to move the truck 3 up and down. Note that a rotary drive machine (not shown) is connected to one of the sprockets 14 or 15.

The end of the horizontal movement rail 1 is the vertical movement rail 5
It serves as a carry-in/out end for carrying in the cart 3 from the lateral movement rail 1 or, conversely, for carrying it out from the horizontal movement rail 1 to the elevating movement rail 5. A cart pushing means 18 for pushing the cart toward the carrying-out end is provided at the carrying-out end.
Bogie restraining means 19 for restraining in synchronization with are provided respectively. Note that the carrying-in end and the carrying-out end are interchangeable depending on the circulation direction of the cart 3. Therefore, the cart pushing means 18 and the cart restraining means 19 have the same structure, and one is the same as the cart pushing means 1.
8, the other one acts as a bogie restraining means 19. For example, if the end of the upper lateral movement rail 1 on the vehicle entry/exit section 9 side is the loading end, the other end of the upper lateral movement rail 1 is the unloading end, and the lower lateral movement rail located below this unloading end. One end becomes the carry-in end, and the other end becomes the carry-out end.

The bogie pushing means 18 and the bogie restraining means 19 have sprockets 20 and 21 disposed at both ends in the longitudinal direction of each of the traverse auxiliary rail sections 11, an endless chain 22 stretched between both sprockets, and an endless chain 22. It consists of a fixed receiver 23,
This receiver 23 is connected to the groove 24 of the traverse auxiliary rail section 11.
It is supported so that it can freely slide along the inside. Therefore, when functioning as the truck pushing means 18, the truck 3 is moved laterally by pushing the auxiliary wheels 6 or axles 7 located in the grooves 24 of the traverse auxiliary rail section 11 with the support 23 as shown in the upper part of FIG. The carriage restraining means 19
As shown in the lower part of the figure, when the auxiliary wheel 6 enters the groove 24 of the traversing auxiliary rail section 11 by pushing out from the opposite side, the receiver 23 catches the auxiliary wheel 6 and suppresses its entry, moving the trolley 3 up and down. It will be stopped at the position of the rail 5. A rotary drive machine is connected to the sprockets 20 and 21 constituting the truck pushing means 18 and the truck restraining means 19, and is configured to drive the opposing receivers 23 in synchronization.

In addition, the rail 5 for vertical movement and the rail 1 for lateral movement
Since it is difficult to maintain the trolley 3 horizontally at the intersection with the intersection, guide rollers 25 for locking the trolley 3 are provided at the intersection, as shown in FIG. In this case, the guide rollers 25 are constructed so as to be able to appear and retract freely so as to be disposed only when the cart 3 reaches the intersection so as not to interfere with the upward and downward movements of the cart 3.

Next, the operation of the above embodiment will be described.

First, when entering the warehouse, a vehicle is transferred from the vehicle entrance/exit section 9 onto the trolley 3 that is positioned and waiting in the vehicle entrance/exit section 9, and the trolley 3 is lowered by rotation of the chain 16 that constitutes the trolley elevating means 13, for example. It is positioned and stopped at the end of the upper lateral movement rail 1. Then, when the chain 22 constituting the truck pushing means 18 is rotated, the support 23 pushes and moves the auxiliary wheels 6 to move the truck 3 onto the upper lateral movement rail 1.
Move it horizontally upwards.

On the other hand, the cart 3 located at the unloading end on the upper lateral movement rail 1 is pushed out toward the vertical movement rail 5 by the above-mentioned lateral movement. By receiving the auxiliary wheels 6 of the truck 3 and being driven in synchronization with the truck pushing means 18, it is possible to absorb the impact applied to the truck 3 while preventing it from jumping out excessively and making noise. It can be stopped at a fixed position.

Next, when leaving the warehouse, until the target trolley 3 is located on the elevating movement rail 5 on the vehicle entrance/exit section 9 side,
When the trolley 3 is circulated by the trolley pushing means 18, the trolley restraining means 19, and the trolley lifting means 13, and the target trolley 3 is located on the above-mentioned lifting/lowering rail 5,
The circulation operation is stopped and the chain 16 of the truck lifting means 13 is rotated. This rotation of the chain 16 causes the hook 17 to hang on the axle 7 of the auxiliary wheel 6.
By transferring this and moving the trolley 3 upward to the vehicle entrance/exit section 9, the vehicle becomes ready for ejection.

In this way, vehicles can enter and exit the warehouse smoothly.
Since the lateral movement of the lateral movement rail 1 is carried out using the so-called tokoroten method in which the cart on the carry-in end side is pushed in and the cart on the discharge end side is carried out, there is no need for a coupler to connect the carts 3. There is no need to form a rack in 3. Therefore, the structure is simplified, which can contribute to making the device more compact and reducing costs. Furthermore, since the group of carts on the lateral movement rail 1 is moved while being held between both ends by the cart pushing means 18 and the cart restraining means 19, the group of carts on the lateral movement rail 1 is moved while being sandwiched between the carts by the cart pushing means 18 and the cart restraining means 19. Therefore, unlike the case where there is a gap between the carts, collisions between the carts are reduced, and noise caused by collisions is reduced.

Furthermore, since the structure is such that the trolley 3 runs directly on the rail 5 for vertical movement, there is no need for a movable rail, and the space can be reduced accordingly.
There is no need for a mobile deck etc. Also,
Since the cart 3 is supported by three-point support when moving up and down, the cart 3 can be moved up and down while being maintained horizontally. Since the lifting, lowering, pushing, and restraining of the cart is performed only by the rotation of the chains 16 and 22, both the mechanism and the operation are simple. In addition, in the embodiment, the lateral movement rail 1
Although a case has been described in which the horizontal movement rail 1 has two stages, the lateral movement rail 1 may be configured to have three or more stages.

In summary, the present invention exhibits the following excellent effects.

(1) The need for connectors, racks, etc. can be eliminated, the structure can be simplified, the device can be made more compact, and costs can be reduced.

(2) It is possible to move horizontally by eliminating gaps between the carts, and it is also possible to absorb shocks such as the carts popping out at the delivery end, reducing noise as much as possible when moving the carts. Can be done.
