Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a puzzle type parking device on a flat floor.

[Conventional technology]

The most common surface parking method is to provide a passageway on the parking floor for cars to enter and exit, and park on both sides or one side of the passageway.In this method, the passageway occupies a large proportion of the area, and the parking floor is occupied by a large proportion of the area. It is uneconomical because the area cannot be used effectively.

Therefore, in order to make effective use of the parking floor, we have developed a horizontal circulation method in which pallets carrying cars are conveyed in a circular manner on a flat floor using a chain conveyor, and a conveyor carrying pallet carts carrying cars is conveyed vertically and horizontally on a flat floor. A line change mechanism is installed at the intersection of the vertical and horizontal conveyor lines to raise and lower the pallet truck, allowing the conveyor line to be transferred from vertical to horizontal and from horizontal to vertical. A flat puzzle type parking device that can be moved and stored in a manner similar to the above has been proposed.

[Problem to be solved by the invention]

However, horizontal circulation type parking devices are uneconomical because they have high equipment costs, make a lot of noise, and cannot use a flat surface equal to the width equivalent to the sprocket diameter of the chain conveyor x the length of the conveyor for parking. In addition, the flat puzzle type parking device is equipped with vertical and horizontal conveyor lines and a line change mechanism that moves up and down.
The equipment costs are high, noise and vibration are large, and there are multiple line change mechanisms, making maintenance and safety management difficult.

This invention solves such problems in parking devices on flat floors, and can effectively utilize the area of the parking floor to increase storage capacity, has a simple structure, reduces noise and vibration, and is easy to maintain and manage. The purpose is to provide an easy parking device.

[Means to solve the problem]

The parking device of the present invention has a flat floor with multiple rows and columns of parking sections, and rails are laid in each row and each column, and each parking section is provided with a stator of a linear motor and a fixing device that rotates the stator. A sub-swivel device is provided, and at the intersection of the rails in each row and each column, a branch rail and a swivel device for rotating the branch rail are provided. The above-mentioned problem is solved by arranging pallet carts equipped with wheels that turn as the branching rail turns, one less than the number of parking spaces.

[Effect]

There are fewer pallet trucks than there are parking spaces on the flat floor. This pallet truck is equipped with a running element of a linear motor, and a stator is rotatably provided in each parking area. In addition, when the wheels of the pallet truck stop on the branch rail, if the branch rail is turned, the wheels will turn together with the branch rail. By driving the pallet truck, the pallet truck can be moved in any direction in one row or column. Therefore, when entering the warehouse, the car can be placed on an empty pallet truck at the entrance and exit, and using one vacant parking area, the pallet truck can be moved sequentially in a puzzle style and stored in any parking area. . When leaving the warehouse, the target pallet truck is similarly moved to the entrance/exit.

〔Example〕

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view showing the arrangement of parking bays according to an embodiment of the present invention, and this embodiment has two rows and two columns of parking bays pH, PI□+P211 P2□ on a flat floor 1. There is. Therefore, rails 2 are laid in each row and column, and ζ
A branch rail 3 and a rail turning device 4 for turning the branch rail 3 are provided at the intersection. In addition, each parking area pH, PI3. A stator 5 of a linear motor and a stator rotation device 6 for rotating the stator 5 are provided in the center of the PZI+P22. Three pallet carts 7 are arranged on the rail 2, one less than the number of parking sections. When the pallet truck 7 stops at a predetermined storage position in each parking area, it is located on the branch rail 3 as shown in FIGS. Wheels 9 and guide wheels 10 are provided that rotate around a pivot shaft 8 as the vehicle turns.

Further, on the lower surface of the pallet truck 7, as shown in FIG. 4, a running element 11 of a linear motor made of a permanent magnet is provided in a cross shape. A fixing device 12 prevents the pallet truck 7 from moving when the stator 5 of the linear motor is not energized, and is released when the stator is energized to allow the pallet truck 7 to move.

FIG. 5 is a block diagram of the control system of this embodiment.

Here, 13 is a cart position detector 14 for detecting the position of the pallet cart 7 within each parking area pH...P2□.
15 is a truck number detector for identifying the pallet truck 7 in each parking area pH...P2□, and 15 is a vehicle detector for detecting whether a car is mounted on each pallet truck 7. , 16 is a rail direction detector that detects whether the branching rail 3 of each parking area P, . . .

The storage status is displayed on the screen of the operation panel 20.

In the standard state of this embodiment, parking area P2□ is an empty parking map, and pallet carts 7 are arranged in each of the remaining parking maps.

When parking a car, when a parking instruction is given on the operation panel 20, the CPU 21 selects an arbitrary empty pallet truck 7k, and moves the parking map from the parking map Pij on the pallet truck 7 to the parking map P2□ which is the entrance/exit. pallet truck 7k
The optimum movement order of each pallet truck 7 is determined to move the pallet truck 7, and control is sequentially applied to the rail rotation device 4 of the branch rail 3, the stator rotation device 6 of the linear motor, the stator 5, and the fixing device 12 of the pallet truck 7. Output a signal. Then, the rail turning device 4 and the stator turning device 6 of the parking map where the pallet cart 7 to be moved first is located are driven to turn the branch rail 3 and the stator 5 in the advancing direction of the pallet cart 7, The fixing device 12 is released and the stator 5 is energized.

When the stator 5 is excited, a traveling magnetic field is generated, and the traveling element 11
moves the pallet truck 7 in the direction of the advancing magnetic field. Since the running element 11 uses a permanent magnet, it does not slip when interacting with the traveling magnetic field generated by the stator 5. Further, by changing the frequency, speed adjustment can be easily performed.

When the pallet truck 7 moves to the next parking map, it stops on the branch rail 3 based on the signal from the truck position detector 13, and the above operation is repeated again.

This movement order, which is the solution to the puzzle, is based on each parking map pH...
