Abstract

PURPOSE:To shorten waiting time during busy hours at a parking lot equipped with a self-propelling stand by providing a temporary storage for empty pallets under the floor surface of the entrance, and by storing the empty pallets in the temporary storage as occasion demands. CONSTITUTION:One parking section S1 of a parking lot S is made to be a port 1 for entrance and exit of cars, and a pit is dug under the floor surface of the section S1 and a plurality of pallets and a pallet lifting device are provided in the pit. A pallet loaded with a car moves being mounted on a travelling stand that travels on rails. When a car in the section Q requires exit following the exit of a car in the section P, pallet from which the car that had been parking in the section P was unloaded for the exit is temporarily stored in the pit in the section S1, and the travelling stand is directly sent to the section Q. The pallet that was temporarily stored in the pit can be put back to the section P when there is an occasion for the travelling stand to travel to a position nearby to the section P. Therefore, waiting time for users can be shortened.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a parking lot that attempts to effectively use a site as a parking space by using a pallet on which a vehicle can be placed and a self-propelled frame that can move this pallet. It is related to.

(Prior Art and Problems to be Solved) Conventionally commonly used parking lot systems can be roughly divided into self-propelled and mechanical systems.

Self-propelled vehicles move in and out of parking locations by themselves, and while this does not require mechanical equipment, it does require a large amount of space for the vehicle to run, resulting in inefficient use of space. There is a point.

Mechanical systems include (a) circulation system, (b) single elevator system, (C) slide system, (d) combined elevator and slide system, and (e) two-stage system.

(a) Circulation method This method connects a number of pallets on which vehicles are placed and circulates them, allowing vehicles to be loaded and unloaded at specific locations. Although it is efficient in terms of space, it Since a series of pallets must be moved every time a vehicle enters or exits, large-scale equipment is required, which increases costs and takes time to move vehicles in and out.

In addition, (b) The following methods (C), (d), and (e) are all more efficient in terms of space usage than the self-propelled type described above, but they still require space for moving the vehicle. In addition, there is a problem in that it requires a considerable amount of mechanical equipment, although it is not as large as the circulation method in (a).

From the above-mentioned viewpoint, the inventor of the present invention previously proposed a method for storing the vehicle in a parking lot in Japanese Patent Application No. 62-158810, with the aim of making it possible to utilize the site effectively with relatively simple mechanical equipment. The vehicle is placed on the pallet, the pallet and the vehicle are lifted upward by a self-propelled platform that straddles the vehicle on the pallet, the self-propelled platform is moved to a predetermined position by a guidance device, and the vehicle is placed on the floor together with the pallet. We proposed a parking lot where people could unload and park their cars.

However, in such parking lots, pallet travel time is related to waiting time, so if unloading and loading are carried out regularly and alternately, there will be no loss of travel time, but if unloading and loading are carried out in a regular manner, there will be no loss of moving time, but if loading and unloading are concentrated in time. If this occurs continuously, there is a problem in that if there is a step in which only empty pallets are transported, this will lead to an increase in waiting time for users.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, vehicles to be stored in a parking lot are placed on a pallet, and a self-propelled platform that straddles the vehicles on the pallet is used. A temporary storage facility for empty pallets below the floor level of the entrance in a parking facility where each pallet vehicle is lifted upwards, moved to a predetermined position by a self-propelled platform, and then lowered and parked together with the pallet on the floor. A parking lot is configured such that empty pallets are stored in the temporary storage area as needed.

(Function) As described above, in the present invention, in a Z-shaped parking facility that uses pallets to effectively use the site as a parking space, temporary storage equipment for empty pallets is provided below the floor level of the entrance. Empty pallets are stored in the temporary storage location as needed, so that the pallet can be moved between the coordinates of each storage position of the pallets arranged in a plane and the coordinates of the pallet placement position at the entrance/exit. Device(
The flow line of the self-propelled mount can be made to have less waiting time and no waste.

In other words, during busy times when the self-propelled platform must operate continuously, when the movement of returning an empty pallet to its original position is more than a certain distance from the flow line of the next self-propelled platform, By storing the items in a temporary storage area provided at the entrance/exit, it is possible to reduce the waiting time for users during busy times.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is the floor surface of the parking lot, and 2 is a division line that divides the floor surface 1 of the parking lot vertically and horizontally into parking spaces S for each vehicle.

In this embodiment, as many pallets 3 as there are parking spaces S (excluding entrances and exits) are prepared on which vehicles to be stored in the parking lot can be placed.

2 and 3 show details of the pallet 3. FIG. That is, this pallet 3 has a rectangular planar shape, and wheel guide grooves 3a are formed on both left and right sides along its longitudinal direction, and side wall plates 3 of appropriate height are formed on both side edges.
b has been launched.

3C is a reinforcing pipe provided at the upper end of the side wall plate 3b, and 3d is a pipe support provided laterally protruding from the lower end of the side wall plate 3b. It polymerizes with 3C. Also, 3e is the side wall plate 3
These are hanging holes provided at both ends of b.

In this embodiment, as shown in FIG. 1, a parking space S, which is one of the parking spaces S, is used as an entrance, and a bit 4 is formed by excavating below the floor surface 1 of this entrance. A plurality of pallets 3 can be stacked and stored in the pit 4, and a lifting device 5 for the pallets 3 is provided in the pit 4.

Although any type of elevating device may be used for the pallet 3, the device in this embodiment is a pantograph type elevating device. That is, in the figure, 5a is the frame, and 5b is the pantograph.

Moreover, FIGS. 4 to 9 show an example of a self-propelled frame that can straddle the pallet 3, lift the pallet 3, move it to a predetermined position, and lower the pallet 3 onto the floor 1. It is.

In the figure, 6 (see Figures 4, 8, and 9) indicates three rails laid on the floor 1, and 7 indicates a self-propelled frame installed on these rails 6 so as to be able to move laterally via wheels 7a. 7b is the driving motor. This self-propelled frame 7 is structured so that it can straddle pallets 3 placed at predetermined positions in each parking space S on the floor 1, and its upper surface is formed into a rectangular frame shape. ing. As shown by the two-dot chain line in FIG. 5, two rails 8 are laid along the longitudinal direction of the self-propelled pedestal 7 on this upper surface, and a table-shaped moving frame 9 having four legs is installed. is provided on the rail 8 so as to be movable back and forth via wheels 9a provided at the lower ends of the legs. 9b (see FIG. 5) is a motor for moving the same.

Further, as shown in FIG. 6, vertical rods 10G each having a rack 10b are erected at the four corners of a rectangular frame 10a to form an elevating frame 10, and this elevating frame 10 is constructed as shown in FIG. , is provided so as to be freely raised and lowered relative to the movable frame 9.

That is, as shown in FIG. 5, the four vertical rods 10c of the lifting frame 10 are inserted into the holes 9d provided in the top plate portion 9C of the moving frame 9 and the holes 9f provided in the corner portions of the leg support beams 9e. be slidably penetrated through each. 11 in Figure 6 is the vertical rod 10C
The gears mesh with the racks 10b provided in the
(See Fig. 5) is the driving motor.

In addition, a seventh
As shown in detail in the figure, a channel member 10d that fits into the side wall plate 3b of the pallet 3 from above is provided, and the hanging hole 3e
A hole 10e that matches the hole 10e is provided, and a locking rod 12 that can be inserted into and removed from the hole 10e is installed inside the framework 10a solenoid 13.
It is provided so that it can be driven by.

In the figure, 14 is a partition plate fixed to the frame 10a, 15 is a collar plate fixed to the locking rod 12, and 16 is a coil spring interposed between the partition plate 14 and the collar plate 15.

Next, the operation of the apparatus configured as described above will be explained. First, as shown in FIG. 8, the vehicle M to be parked moves in the direction of arrow A from the position marked with ■, and gets onto the pallet 3 placed on the entrance S1, which is a specific space.

That is, as shown in FIG. 9(a), the vehicle M is loaded onto the pallet 3 on the floor 1. Next, Figure 9(b)
As shown in the figure, the self-propelled frame 7 is positioned above the entrance/exit S1, and the movable frame 9 and the elevating frame 10 are positioned directly above the pallet 3 above the entrance/exit, and in this state, the elevating frame 10 is lowered. Then, as shown in FIG. 7(a), the groove member 10d of the lifting frame 10 is fitted into the side wall plate 3b of the pallet 3. At this time, the locking rod 12 is in a retracted state against the coil spring 16 due to the bias of the solenoid 13.

In this state, the power to solenoid 13 is cut off and solenoid 1 is turned off.
3 is demagnetized, the locking rod 12 moves outward as shown in FIG.
0e and the hanging hole 3e, the lifting frame 10
and pallet 3 are connected.

Therefore, if the elevator frame 10 is raised in this state as shown in FIG. 9(d), the vehicle M will be raised together with the pallet 3. That is, as shown in FIG. 8, the vehicle on the pallet 3 rises in the direction of arrow B from the position ■ to the position ■. Next, the self-propelled frame 7 moves from the position ■ in the direction of arrow C by the operation of the self-propelled frame 7, and from the position ■, the moving frame 9 moves further in the direction of the arrow as shown in FIG. 9(e). Move by moving above, and at the position of
As shown in Figure (f), by lowering the elevator frame 10, the pallet 3 is lowered as shown by arrow E in Figure 8, and the vehicle M is parked on the floor 1 while remaining on the pallet 3. .

Once the pallet 3 is placed on the floor 1, the locking rod 12 is moved to the seventh position by energizing the solenoid 13 shown in FIG.
By retracting the pallet 3 as shown in figure (a),
is separated from the lifting frame 10.

After the pallet 3 is released, the lifting frame 10 is raised as shown in FIG. 9(g), and then the self-propelled frame 7 and the lifting frame 10 are moved to the parking position of the vehicle to be taken out of the parking lot. Then, after lifting the vehicle together with the pallet 3 onto the self-propelled platform 7 and moving it to the entrance S1, which is the specific space, lower the vehicle M together with the pallet 3 onto the floor 1 at that position, and then move the vehicle M together with the pallet 3 onto the floor 1. It can be taken out from the pallet 3 by self-propulsion.

The above explanation is an example of a method of parking in one parking space S, but in such a parking lot system, the length of time required to move the pallet 3 greatly affects the waiting time of the user.

In other words, in this case, if the unloading and loading of vehicles are carried out regularly and alternately, there will be no loss in the use of pallets and no loss in time for moving pallets, but if unloading or loading is concentrated in time, If this occurs continuously, there will be wasted time transporting only empty pallets, which will increase the waiting time for users.

To explain this specifically for the parking lot shown in FIG. 10, suppose that after a vehicle at position P in the parking lot leaves the parking lot, a vehicle at another position Q subsequently leaves the parking lot.
If P and Q are close to each other as shown in Figure 10(a), there will be a time loss even if you return the empty pallet from P's vehicle to P and then go to retrieve Q's vehicle. Although there are few
If P and Q are far apart as shown in FIG. 10(b), it will be a waste of time to return the empty pallet to P. Therefore, if the empty pallet after the vehicle P leaves is temporarily stored near the entrance S1 and the vehicle goes directly to Q, time can be saved. The stored pallet can be returned to P the next time you go near P.

For the above-mentioned reasons, the present invention provides a parking facility that uses pallets to effectively utilize the site as a parking space, by providing a temporary storage facility for empty pallets below the floor level of the entrance and exit, and storing empty pallets as needed. is stored in the temporary storage location.

In the temporary storage facility of this embodiment, as described above, a bit 4 is formed by excavating the area below the entrance/exit S1, and a pantograph type lifting device 5 is provided within this bit 4.

That is, in order to temporarily store the pallet 3, the pallet 3 is placed on the lifting device 5, and in order to further store another pallet 3, the lifting device 5 may be lowered by an amount equivalent to the thickness of the pallet 3. When the pallets 3 that have been temporarily stored in this way are to be reused, the lifting device 5 may be operated so that the uppermost pallet 3 is located above the level of the floor 1.

In order to determine which pallets are to be stored temporarily and which are not, the entire parking lot is divided into blocks for each adjacent location (this block is not fixed, but can be a flexible block that is considered each time). Just think about it.

FIG. 11 shows an example of a method for determining whether or not temporary storage of a pallet is necessary based on the pallet arrangement coordinates.

In other words, FIG. 11(a) is a plan view of the parking lot showing the arrangement coordinates of all pallets, and FIG. 11(b) is a plan view of the parking lot showing the arrangement coordinates of all pallets.
Fig. 11 (C), (d), (e
) is an explanatory diagram of the same coordinates as in FIG. 11(a).

In Fig. 11 (C), (d), and (e), if the position of the first pallet to be delivered is indicated by a ◎ mark, the waiting time for the next pallet to be delivered does not exceed a certain limit. Such an area can be represented by a circle corresponding to the coordinates of the pallet that was shipped immediately before the area.

In other words, if the position of the next pallet to be delivered is in the area marked with a circle in relation to the coordinates of ◎ that were delivered immediately before, the empty pallet that was delivered immediately before is returned to its original position, and the next pallet is delivered. That's fine.

Also, the coordinates of the next pallet are those of the pallet that was delivered just before◎
If the empty pallet is returned to the outside of the designated area (other than the area A), returning the empty pallet will cause a loss in the flow line, and the waiting time for the next delivery will exceed the limit, resulting in a decline in service. If so, empty pallets should be temporarily stored in a storage area near the entrance. That is, without returning the empty pallet to its original position, the conveyance device goes directly to the next pallet position and performs an operation for unloading the pallet. The temporarily stored pallet can be returned to its original location when it becomes necessary to perform a warehousing operation or to move the pallet into a section marked with a Q mark relative to the coordinates of the original pallet.

(Effects of the Invention) As described above, in the present invention, in a parking facility in which pallets are used to effectively utilize the site as a parking space, temporary storage facilities for empty pallets are provided below the floor level of the entrance. Empty pallets are stored in the temporary storage location as needed, so that the pallet can be moved between the coordinates of each storage position of the pallets arranged in a plane and the coordinates of the pallet placement position at the entrance/exit. Device(
The flow line of the self-propelled mount can be made to have less waiting time and no waste.

In other words, during busy times when the self-propelled platform must operate continuously, when the movement of returning an empty pallet to its original position is more than a certain distance from the flow line of the next self-propelled platform, By storing the items in a temporary storage area provided at the entrance/exit, it is possible to reduce the waiting time of users during busy times.
