2. Description of the Related Art In a conventional parking apparatus, an elevator is waiting at a floor position at a landing, and a vehicle entering the landing comes in. By issuing a parking instruction, the vehicle at the landing is mounted on an elevating lift, ascends and descends to the storage floor, is delivered to the transverse tray in the parking room, and is stored in the parking room. The elevating lift is suspended from a driving unit installed on the upper part of the parking device, and is raised and lowered by winding up and rewinding by rotation of a driving motor.

[0003] In the parking operation, the lift is moved up and down to the parking room, and the vehicle is received and mounted from the traversing tray of the parking room. Start the vehicle on the top and complete. The lifting of the lift is controlled by the inverter to stop the drive motor from acceleration to high speed, and then to deceleration to low speed. Each stop position is determined by the number of rotations of an encoder provided with a drive motor, and is determined by software of a sequencer that stores the position as an address based on the number of rotations.

[0004]

However, in the parking operation of the conventional parking device, the weight of the vehicle to be stored varies from light to heavy, and the vehicle can be controlled if it is within the weight that can be mounted on the lift. The speed of the lifting lift can be low, high speed, low speed, and stop operation can be performed normally, but when a vehicle with an unspecified weight is mounted, the speed of the lifting lift will be different and when lifting heavy objects Slower, faster when descending heavy. When the speed of the lifting lift is slow and fast, the stop position is shifted even if the stop signal operates normally, so that the low speed control can be performed from a position far from the stop position, or the vehicle can stop at the specified position after passing the stop position. There was a problem that there was not.

[0005] In particular, when a heavy vehicle is taken out of the vehicle, the vehicle is received from the traversing tray, and when the vehicle descends toward the landing, an inertia force corresponding to the lift / lift and the weight of the vehicle acts, and braking by the power of the drive motor becomes impossible. As shown in b), the high-speed area extends, the deceleration area becomes longer, the low-speed area almost disappears, and the vehicle reaches the floor, so that the vehicle comes into strong contact with the floor and the vehicle is damaged. Become. The present invention is directed to a control method for controlling the vertical speed of a conventional vertical lift to perform high-speed, low-speed, and stop operations according to the vehicle weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a parking tower 1 as one embodiment,
FIG. 4 is an explanatory view showing a driving device of the lifting / lowering lift 3, in which the lifting / lowering lift 3 carries a vehicle in the lifting / lowering space 6 of the parking device 1, carries the vehicle to the parking room 2, and enters and leaves the parking space. The landing 7 is on the ground surface G
It is installed on the floor of L as the position of the lift space 6 and the parking room 2.

The parking room 2 is provided adjacent to the elevating space 6, and has the traversing tray 4. The traversing tray 4 can reciprocate between the parking room 2 and the elevating space 6, and protrudes a comb-shaped fork (not shown) from the center outward to the left and right. The reciprocating motion between the parking room 2 and the elevating space 6 is such that a tray receiver 5 on which a plurality of rollers for supporting the left and right sides of the traversing tray 4 is mounted is disposed in the parking room 2 and the elevating space 6. Moves.

The lift 3 is guided by guide rails 11 erected at the four corners of the lift space 6, and is suspended by a chain 10 from an upper sprocket 9. A driving device is installed above the elevating space 6, and the chain 10 is wound up and rewinded to thereby guide the rail 1.
With the guidance of No. 1, the lift 3 moves up and down from the landing 7 to the top floor.

In the driving device, a reduction gear G serving as an output section of a driving motor M is provided at an upper portion of the parking tower 1. The reduction gear G is provided with a driving sprocket 8, and is wound around a sprocket 9 at an upper end of a guide rail 11. Around the chain 10
The weight W is suspended downward. Weight W
In order to reduce the size of the drive motor M by reducing the load on the drive motor M for energy saving, the weight of the lift 3 and the weight of the vehicle mounted on the lift 3 are combined.

The elevating lift 3 has a comb-tooth shape, and protrudes inward from the outside in parallel with the forks of the traversing tray 4 so as to pass between the forks of the traversing tray 4 so as to pass through the comb teeth of the traversing tray 4. ing. The landing 7 is on the ground surface G
L and the floor 12 and the lift 3
Can easily enter 7.

The vehicle can be loaded and unloaded to and from a designated floor by the operation panel S. When the motor M rotates, the drive sprocket 8 provided in the speed reducer G rotates and the chain 10 is suspended vertically by a rotatable sprocket 9 which is pivotally mounted on the upper part of the guide rail 11 when the motor M rotates. Therefore, it moves along the guide rail 11. The rotation speed of the drive motor M can be changed for each application by the inverter I, and can be changed from low-speed start to medium speed, high speed, medium speed, low speed, and stop. The position at which the speed is changed is determined by the encoder E. The entry and exit of the parking room 2 on each floor is managed by the sequencers C1 and C2 in relation to the elevation position of the elevation lift 3 and the movement timing of the traversing tray 4.

(Reception operation) The vehicle to be stored is on the ground surface GL.
The vehicle enters the landing 7 from above and stops on the lift 3 that forms the floor 12. The parking room 2 to be entered will be described with reference to the block diagram shown in FIG.
The lift 3 mounts the vehicle and starts to rise. In the sequencer C1, the timer T1 is turned on at the same time when the lifting / lowering lift 3 is raised, and the sequencer C1 is raised to a set value (rotation quantity / parking room position / rotation speed change position) for measurement. For example, in FIG. 3, the rotation speed is set to a set value, and the load is in the acceleration region 19, and the load when the lifting lift 3 rises is stored in the timer T1 and input to the sequencer C2 as the warehousing information.

The sequencer C2 groups the weights of the vehicles by the timer T1 and stores them together with the parking room 2.
The grouping of the timer T1 is performed in the acceleration region 1
The time at which the lift 3 arrives at the position set at 9 is defined as the heavy vehicle entrance time Ta. In the case of the standard vehicle, the vehicle is lighter than the heavy vehicle, so the acceleration is faster and the standard vehicle entrance time Tb.
Becomes Since the light vehicle entry time Tc is lighter than that of the standard vehicle, it enters the high-speed area 20 fastest in the acceleration area 19,
The vehicle stops at a position above the parking room 2 after passing from the deceleration region 21 to the low speed region 22. The timer T1 of each vehicle that has entered the parking lot is input to the sequencer C2 and stored as the timer T1, and the parking room 2 is also stored at the same time.

In the lift 3, the rotation speed of the drive motor M is set to an acceleration area 19, a high-speed area 20, a deceleration area 21, and a low-speed area 22 so that the speed of the elevator E is the best time to enter the warehouse. The ascending lift 3 determines the stop position, and stops at a position above the parking room 2 where the parking is to be performed. Then, the traversing tray 4 moves from the parking room 2 to the ascending / descending space 6, and the elevating lift 3 descends and traverses. Move the vehicle to Tray 4. The traversing tray 4 carries the vehicle and traverses back to the original parking room 2. The elevating lift 3 starts descending and returns to the landing 7 to complete the storage.

(Exiting operation) When the parking vehicle 2 is designated by the operation panel, as shown in the block diagram of FIG. 4, the vehicle to be exited raises the lifting / lowering lift 3 by the software of the sequencer C2, and exits from the parking room 2. Trays 4 equipped with
Is traversed to the lifting space 6. The lift 3 receives the vehicle after passing the traversing tray 4 and stops. The elevating lift 3 equipped with the vehicle has a timer T1 input at the time of entry into the warehouse.
With the set time converted from the information from the timer T2, the sequencer C2 starts to descend as software. FIG.
As shown in (b), by adjusting the time of the high-speed area 21, it is possible to smoothly land on the floor surface 12 of the landing 7 in a low-speed area where there is no impact.

In the standard vehicle, the vehicle is received from the traversing tray 4, starts descending, enters the high speed region 20 from the acceleration region 19, and continues for the set time Ty of the standard vehicle of the timer T2 in the deceleration region 2.
1 and stop on the floor 12 of the landing 7 in the low-speed area 22. When the lifting lift 3 that has received the vehicle from the traversing tray 4 starts descending, the acceleration of the heavy vehicle with the weight of the lifting lift 3 and the vehicle is greater than the power of the drive motor M, so that the braking control slips. Then, the acceleration occurs and the acceleration becomes larger than that of the standard, and enters the high-speed region 20.

In the high speed region 20, the timer T2 drives the heavy vehicle for the set time Tx. The heavy vehicle set time Tx in the deceleration region 20 is shorter than the standard set time Ty and the deceleration region 21 is made longer. Therefore, the lowering position does not become the lowering position due to the inertial force of the heavy vehicle, and the vehicle can be stopped accurately on the floor surface 12 by the long deceleration region 21.

In the case of the set time T of the light vehicle, the weight of the lifting / lowering lift 3 plus the light vehicle is lighter than the standard, so that it does not extend in the acceleration region 19, and the lowering position is lowered by lengthening the high speed region 20. In other words, since the power of the drive motor M is larger, even if the deceleration region 21 is shortened, the floor 12 can be stopped at a low speed in the low speed region 22 sufficiently. The time required for the lift 3 to reach the floor 12 can be set to substantially the same value for both light and heavy vehicles. In the embodiment described above, when the parking room 2 is located at a position above the landing 7,
Although the operation of entering and exiting the parking room 2 has been described, when the parking room 2 is located below the entrance 7, the entry time and the set time are determined by software for the lower side, which is different from software for the upper side. .

The software for lowering the vehicle is such that the elevator 3 mounted with the vehicle rises above the floor surface 12 when the vehicle is parked, and the parking time Ta of the heavy vehicle, the warehouse time Tb of the standard vehicle, and the warehouse time Tc of the light vehicle are calculated. The sequencer C1 stores the timer T1 and determines the set time Tx of the heavy vehicle, the set time Ty of the standard vehicle, and the set time Tz of the light vehicle. The lift 3 is lowered to the parking room 2. The traversing tray 4 in the parking room 2 traverses to the elevating space 6 and receives the vehicle of the elevating lift 3. The unloading operation is increased by the set-up time corresponding to the vehicle weight by the unloading sequencer C2 and the timer T2 based on the in-store information of the sequencer C1.

[0027]

According to the first aspect of the present invention, it is determined whether the vehicle is heavier or lighter than the standard vehicle based on the time when the lift is mounted on the vehicle and is measured at an arbitrary position in the acceleration area by the rotational force of the drive motor at the time of entry. By changing the parking room and measurement time to software using a dedicated sequencer for departure and changing the time in the high-speed area according to the vehicle weight, even a heavy vehicle can provide a sufficient low-speed area and contact the floor surface This has the effect of preventing a light vehicle from taking a long time to leave the vehicle in a low-speed region, and a stable leaving time can be obtained regardless of the vehicle weight. According to the second aspect of the present invention, the lifting lift can stop on the floor of the landing in the low-speed area, so that even a heavy vehicle can land on Sooms. According to the third aspect of the present invention, the elevating lift can carry the vehicle and smoothly deliver the vehicle to the traveling vehicle as the transfer destination at a low speed. According to the fourth aspect of the present invention, a large-capacity storage device is required to store a plurality of vehicle weight data.
By setting a standard and grouping it into a larger one and a smaller one, the capacity can be reduced, resulting in an inexpensive device.
