DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multi-layer circulating parking system.

[0002]

2. Description of the Related Art In a building city such as a city center, the land price is extremely high, and it is difficult to secure a sufficient space for a parking lot. .

FIG. 3 shows an outline of a conventional multilayer circulation type parking facility.

[0004] On the first floor of the building 10, there is an entrance / exit 1 for cars, and a pallet 2 on which vehicles are placed is placed on the upper horizontal transfer path 3 and the lower horizontal transfer path 4 under the car. A plurality are mounted so as to be movable in the horizontal direction.

The upper horizontal transfer path 3 and the lower horizontal transfer path 4 are provided with horizontal driving means (not shown) for transferring the placed pallets 2 in the horizontal direction.

Reference numeral 5 denotes a loading / unloading lift, and reference numeral 6 denotes a circulation lift, which is a vertical lift for transferring the pallet 2 to the loading / unloading port 1, the lower horizontal transfer path 3 and the upper horizontal transfer path 4. Driven by 7 and 8.

Reference numeral 9 denotes a control device for the multi-layer circulation type parking equipment. The control device 9 causes the horizontal drive means, the loading / unloading lift 5 and the circulation lift 6 to alternately repeat horizontal transfer and vertical transfer. A desired pallet can be called to the loading / unloading port 1 under unified control.

In this case, the circulation direction of the pallet 2 is clockwise or counterclockwise depending on the position of the pallet to be called. Therefore, the loading / unloading lift 5 and the circulation lift 6 are changed according to the rotation direction. They will be used for ascending and descending respectively. Since the loading / unloading lift 5 and the circulation lift 6 are of an endless type in which the circulation transfer belt is rotated, when raising the pallet,
A hoisting load is applied to the drive motor, and a lowering load is applied when the drive motor descends.

Usually, since a large load is applied to the drive motor during winding, a motor having a considerably large output compared to the motor used for the horizontal drive means is used.
Therefore, when the loading / unloading lift 5 and the circulation lift 6 are operated at the same time, a very large starting current for two drive motors is required, and equipment having a large required power supply capacity is required. The lift (for example, the loading / unloading lift 5) is always started with priority regardless of the pallet circulation direction, and immediately thereafter, the other vertical lift is started, so that the start of the two drive motors is shifted. Was so controlled.

The control operation in this case will be described with reference to the flowchart of FIG. (1) The control device 9 is set in a start state, and a pallet to be called is registered in the control device 9 (step s).
1). (2) With this call registration, the pallet circulation direction is determined so that the pallet is transferred to the entrance 1 in a short time as possible (step s2).

For example, when the pallet to be called is at the position 2a, the pallet is circulated to the left, and
Is controlled to be rotated rightward. (3) Regardless of whether the rotation direction is left or right. First, the entry / exit lift 5 is driven (step s3). (4) Thereafter, the circulation lift 6 is driven (step s4).

By circulating the pallet 2 in this manner, when the target pallet comes to the position of the loading / unloading lift 5,
Drive the loading / unloading lift 5 to raise the pallet,
The pallet is transferred to the position of the entrance 1.

[0013]

In the conventional multilayer circulation type parking facility controlled as described above, the loading / unloading lift 5 is always driven with priority regardless of the pallet circulation direction. If the circulation direction of the pallet selected in step s2 of the flowchart of FIG. 4 is clockwise rotation, the loading / unloading lift 5 moves in a direction to raise the pallet. Immediately after the start, the drive motor 8 is started to start the circulation lift 6 In this case, the required power supply capacity depends on the rated power when the drive motor 7 is wound and the drive motor 8.
Of the starting power of

Normally, the rated power of the pallet horizontal drive means provided in the upper horizontal transfer path 3 and the lower horizontal transfer path 4 does not require much higher power than the drive motors 7 and 8, Since the lateral transfer of the pallet in each transfer path is stopped, the above-mentioned rated power at the time of hoisting by the lift drive motor plus the starting power is required as the minimum required power supply capacity of the parking facility. Become.

[0015] If the required power supply capacity is increased, the cost of construction of the equipment for safety measures is increased, and the basic power charge is also dramatically increased. Therefore, it has conventionally been a problem to reduce the required power supply capacity as much as possible. Was.

In order to achieve the above object, the present invention provides a multi-layer circulation type parking facility which minimizes required power supply capacity and further minimizes power consumption while maintaining the conventional storage capacity and circulation capacity. The purpose is to:

[0017]

In order to achieve the above object, a multi-layered circulating parking system according to the present invention circulates a plurality of pallets on which cars are mounted by horizontal driving means for each layer and two sets of vertical lifts. In the multi-layer circulating parking facility that moves the required pallets to the entrance and exit according to the call, the two sets of vertical lifts are driven by a vertical lift that always lowers the pallets regardless of the pallet circulation direction. Is controlled to drive preferentially, and furthermore, the drive motor of the vertical lift when the pallet is lowered is used as a generator, and power is supplied to the drive motor of the vertical lift when the pallet is raised. It is characterized by the following.

[0018]

Normally, the vertical lift to be lowered can be naturally lowered by the deceleration means due to its gravity without supplying power to the drive motor after the start, so that the vertical lift to be lowered first has priority. By starting the upper and lower lifts to be raised thereafter, the required power capacity as a whole is only the starting power for one drive motor for the upper and lower lifts.

Further, the power consumption can be greatly reduced by using the drive motor at the time of descent as a generator and supplying the generated power to the drive motor of the vertical lift at the time of the ascent.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings, but it is needless to say that the technical scope of the present invention is not limited thereby.

FIG. 1 is a view schematically showing a multilayer circulation type parking facility according to the present invention. For ease of explanation, a two-layer type is shown as in FIG.
Those denoted by the same reference numerals as those in FIG. 3 indicate the same contents.

The control device 11 is connected to a power source 12 and drives the driving motor 7 for the loading / unloading lift 5 and the driving motor 8 for the circulation lift 6, and the horizontal driving path 3 and the horizontal driving path 4 for the lower layer. A means (not shown) is supplied with power to control the unit uniformly, and controls so as to transfer a required pallet 2 to the loading / unloading port 1, and is operated by the next step shown in FIG. (1) After the apparatus is started, the pallet number to be called is registered in the control apparatus 11 (step S1). (2) Determine the position of the registered pallet and determine the pallet circulation direction to call the pallet in the shortest time (step S2). (3) If the counterclockwise rotation is selected in step 2, the loading / unloading lift 5 is exclusively used for descending during pallet circulation, and thus the loading / unloading lift 5 is started preferentially (step S3). (4) After the loading / unloading lift 5 is started, the supply of power to the drive motor 7 is stopped, and the drive is switched to natural lowering by a known deceleration means (not shown) using a combination of gears or the like (step S4). (5) Immediately after this, power is supplied to the drive motor 8 to start it, and the circulation lift 6 is raised. At this time, since a lowering load is applied to the drive motor 7 and it acts as a generator, the internal switch is switched so as to supply this power to the drive motor 8 (step S5). (6) If clockwise rotation is selected in step S2, the circulating lift 6 becomes a descending lift, so this lift is first started (step S6), and then the power supply of the drive motor 8 is stopped to decelerate. (Step S7). Immediately thereafter, the entry / exit lift 5 is driven. At this time, the internal switch is switched so that the electric power generated by the drive motor 8 is supplied to the drive motor 7 (Step S8). .

As described above, when the target pallet comes to the position of the loading / unloading lift 5, the loading / unloading lift 5
Is raised to transfer the pallet to the loading / unloading port 1, and the vehicle is loaded or unloaded. At this stage, the call registration of the pallet first input to the control device is terminated, and the control waits for the input of a new call registration.

When power is supplied to the other drive motor by using the drive motor at the time of lowering as a generator, a sudden rise in voltage may occur and the lift may run away, causing an accident or the like. Therefore, it is desirable to supply power via a constant voltage device for supplying stable power.

When the vehicle is mounted on a pallet to be lifted and transferred when the vehicle is lowered, a significant difference occurs in the lowering speed of the deceleration means. Check the presence or absence of the pallet, and based on this, change the reduction ratio of the reduction means or the load of the drive motor acting as a generator to keep the descending speed constant, so that stable pallet transfer can be performed. It is also possible.

In this embodiment, for convenience of explanation, a two-layer circulating parking facility is shown. However, it goes without saying that the same control can be performed with three or more layers.

In general, the present invention is not limited to parking lot facilities, but can be applied to facilities and devices that require the use of two sets of vertical transfer lifts almost simultaneously.

[0028]

As described above, in the multi-layer circulation type parking facility according to the present invention, the lowering lift is always driven in preference to the ascent lift regardless of the pallet circulation direction. The electric capacity requires only the starting power for one lift drive motor, and the required electric capacity can be greatly reduced as compared with the conventional equipment. It's cheap. In addition, since the drive motor of the lift at the time of descent is used as a generator and the electric power is supplied to the drive motor of the lift at the time of the ascent, the running cost is very low.
