Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a vertical circulation type multi-level parking facility for controlling calling of a cage in the vertical circulation type multi-level parking facility.

[0002]

2. Description of the Related Art Conventionally, there has been a vertical circulation type parking facility in which a plurality of vehicle-mounted cages are rotatably supported in a parking structure, and each cage is operated by calling a desired cage by an operation panel or the like. When the called cage arrives at the entry / exit position, the circulation is stopped and the called cage is moved to the entry / exit position.

[0003] Then, the vehicle is loaded and unloaded with respect to the cage called at the loading and unloading position.

Further, CF control using an electric hydraulic push-up brake has been adopted as a method for controlling the braking of a main motor as a drive source for circulating and circulating each cage.

[0005]

However, the load acting on the drive source depends on various factors such as the arrangement state of the parking cage on which the vehicle is mounted and the empty cage on which the vehicle is not mounted, the position of the called cage, and the like. Since the circulation running speed and the like immediately before arrival at the entry / exit position have changed, it is not possible to obtain sufficient landing accuracy to stop the called cage at the proper entry / exit position, that is, the regular stop position.

When the called cage stops from the normal stop position outside the allowable range, each time,
An operator such as a manager or a maintenance staff has to manually move the cage to a normal stop position to restore it, which is a troublesome work.

In view of the above problems, therefore, the present invention controls a vertical circulation type multi-level parking facility capable of automatically restarting and automatically recovering when a called cage stops outside the normal stop position. The purpose is to provide a device.

[0008]

[Means for Solving the Problems] The technical means for achieving the above-mentioned object is to call a cage by calling a desired cage by supporting a plurality of vehicle-mounted cages so that they can circulate and rotate freely. In the control device of the vertical circulation type multi-story parking facility that is controlled so as to call to the entry / exit position by the circulation running, a normal stop position detector that detects whether the called stop position of the cage is the normal stop position is provided. When the stopped position of the called cage is not detected as a normal stop position by the normal stop position detector, the controller restarts the calling operation again after circulating a certain amount in the circulating direction. Is provided.

Further, the circulation direction of each cage by the calling operation is controlled so as to be the shortest moving direction with respect to the loading / unloading position of the called cage, and the fixed amount may be one cage.

[0010]

According to the present invention, when cages are circulated and circulated by a cage calling operation and the called cages are stopped at the regular stop position of the loading / unloading position, the regular stop position detector normally stops the cages. It is detected that the vehicle is stopped at the position, and then the normal loading / unloading operation is performed.

Next, when each cage is circulated around by the calling operation of the cage and the called cage deviates from the regular stop position of the loading / unloading position and stops, the normal stop position detector detects the normal stop position of the cage. However, the control unit restarts the calling operation again after circulating a certain amount in the circulating direction. Therefore, each cage is circulated again and the called cage is called again to the loading / unloading position.

At this time, if the stopped position of the called cage is the normal stop position, then a normal loading / unloading operation is performed. Moreover, if the stop position of the called cage is again out of the normal stop position, the control unit repeats the above operation. Here, the cage stop position can be automatically restored, the downtime of the machine can be eliminated, and the reliability can be improved.

The direction of circulation of each cage by the calling operation is controlled so as to be the shortest movement direction with respect to the loading / unloading position of the called cage, and when the predetermined amount is one cage. When the cage is called in the shortest movement direction, each cage circulates in the shortest direction, and if the called cage stops at the regular stop position of the loading / unloading position, the regular stop position detector stops the cage at the regular stop position. Is detected, and then the normal loading / unloading operation is performed.

Next, when each cage is circulated around in the shortest movement direction by the cage calling operation and the called cage deviates from the regular stop position of the loading / unloading position and stops, the cage stops at the regular stop position detector. Therefore, it is not detected at the regular stop position, and the control unit circulates one cage in the shortest movement direction, and then restarts the calling operation. Therefore, each cage is circulated once again in the shortest movement direction, that is, in the direction opposite to the previous direction, and the called cage is called again at the loading / unloading position.

At this time, if the stopped position of the called cage is the normal stop position, then a normal loading / unloading operation is performed. Moreover, if the stop position of the called cage is again out of the normal stop position, the control unit repeats the above operation. Here, the cage stop position can be automatically restored, the downtime of the machine can be eliminated, and the reliability can be improved. In addition, when the calling operation is restarted, only one cage is circulated and the time required for the restart is short.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG.
In the parking structure 2, an upper sprocket 3 and a lower sprocket 4 are respectively arranged one above the other, a pair of endless chains 5 stretched between the two sprockets 3 and 4, and an endless chain 5. A plurality of vehicle-mounted cages 7 connected through an attachment 6 are provided, and each cage 7 group is configured to be freely circulated and circulated by a main motor as a drive source linked to the upper sprocket 3 and an interlocking mechanism. There is.

An entry / exit port 8 is formed at the ground floor position as the entry / exit position of the parking structure 2, and the vehicle 9
Is a cage 7 fitted into the pit 10 from the loading / unloading opening 8
It is configured so that it can be loaded onto a mounting base (not shown).

An operation panel 11 is provided at an appropriate height position beside the entrance / exit opening 8 of the parking structure 2, and an operator such as a user operates the operation panel 11 as appropriate to obtain a desired cage. 7 is called to the loading / unloading position.

Further, in FIG. 2, reference numeral 12 is a control unit for controlling the entire vertical circulation type multi-level parking facility 1. In order to send a control signal to the control unit 12, the called cage 7 approaches a position near the loading / unloading position. A deceleration sensor that detects that the car 7 has arrived, a stop sensor that detects that the called cage 7 has arrived at a predetermined position, and a stopped position of the called cage 7 that is suitable for the loading and unloading operations of the vehicle 9. Various sensors such as a regular stop position sensor as a regular stop position detector for detecting whether or not the vehicle is at the stop position are appropriately provided.

Then, the control unit 12 determines the shortest moving direction of the called cage 7 with respect to the loading / unloading position in response to the calling operation of the cage 7 on the operation panel 11, and causes each cage 7 to circulate and run, The called cage 7 is moved to the exit position. At this time, if the called stop position of the cage 7 is not the normal stop position, the cage is controlled so as to be re-started after the cage is further circulated for one cage in the circulation direction.

Next, the operation of the control unit 12 will be described in more detail with reference to the flow charts shown in FIGS.

That is, the desired cage 7 for the operation panel 11
Is input, the number of the called cage 7 is registered in the call cage. Then, in step S1, it is determined whether or not the call cage is registered. If the call cage is registered, the process proceeds to step S2.

Next, at step S2, it is judged if the called cage 7 is not in the loading / unloading position. And if the called cage 7 is not in the loading / unloading position,
In step S3, it is determined whether or not the shortest movement direction of the called cage 7 with respect to the entry / exit position is clockwise. If clockwise, the cage 7 is circulated in a clockwise direction (step S4). If it is not clockwise, it circulates counterclockwise (step S5).

After that, when the called cage 7A moves to the vicinity of the loading / unloading port 8 as shown in FIG. 1 by the circulation running of each cage 7, the deceleration sensor detects it (step S6). The circulation speed is reduced by the signal (step S7). After that, when the called cage 7 is detected by the stop sensor (step S8), the main motor is braked by the detection signal and the circulation running of each cage 7 is stopped (step S10).
The circulation direction is stored immediately before the stop of each cage 7 (step S9).

When the circulation running is stopped, the process proceeds to step S11, and it is judged whether the stop position of the cage 7 called by the normal stop position sensor is a normal stop position within an allowable range in which the storing operation and the leaving operation are possible. To be done. That is, as shown in FIG. 1, the cage 7 is operated by the normal stop position sensor.
When B is detected to have stopped at the regular stop position, the process proceeds to step S12, and the stored circulating traveling direction is cleared. Then, the process proceeds to step S13, the call cage registration is cleared, the restart count number N described later is returned to 0 (step S14), and the series of calling operations is completed.

Then, the loading / unloading operation of the vehicle 9 may be performed on the cage 7 called to the loading / unloading position.

Further, as shown in FIG. 1, if the called stop position of the cage 7C deviates from the normal stop position by more than the allowable range, the step S11 is performed.
In, the cage 7C is not detected by the regular stop position sensor, and it is determined that the cage 7C is out of the regular stop position. In this case, the process proceeds to step S15 and the current count number N
Is incremented by 1, and then the process proceeds to step S16 to determine whether the count number N is 3 or more. If it is 3 or more, the process proceeds to step S12, and if it is less than 3, step S1.
7, the number of the called cage 7, that is, the called cage 7 is stored.

Next, in step S18, after the call cage registration is cleared, it is determined whether the stored circulating traveling direction is clockwise. If it is clockwise, it is circulated and rotated clockwise (step S2).
0), if not clockwise, circulation is performed counterclockwise (step S21).

After that, the process proceeds to step S22, and when the next cage 7 on the rear side of the called cage 7 in the circulation direction moves to the vicinity of the loading / unloading port 8, the cage 7 is detected by the deceleration sensor, and the detection is performed. The circulation speed is reduced by the signal (step S23). Then, when the cage 7 is detected by the stop sensor (step S2
4) Then, the main motor is braked by the detection signal, and the circulation running of each cage 7 is stopped (step S25). Here, as shown in FIG. 1, a state in which the called cage 7D is circulated by one cage, that is, by one pitch of each cage 7 which is circulated, is obtained.

Next, in step S26, the call cage stored in step S17 is called and registered, and then the process proceeds to step S1 to repeat the above operation. At this point, the calling operation will be restarted. On this occasion,
At the time of this restart, the shortest movement direction of the called cage 7 eventually becomes the opposite direction to the above-mentioned circulation running direction.

Then, if the stopped position of the called cage 7 becomes the normal stopping position by this restarting, the loading / unloading operation of the vehicle 9 is carried out with respect to the called cage 7 in the normal loading / unloading position. Good. Further, if the called stop position of the cage 7 is out of the normal stop position again, the cage 7 is restarted again.

As described above, according to the embodiment of the present invention,
Even if the stop position of the cage 7 called to the loading / unloading position deviates from the regular stop position and stops, the cage 7 is automatically restarted, and the cage 7 stop position can be automatically restored here. Therefore, the downtime of the machine is eliminated and the reliability can be improved.

Further, in this restart, since the called cage 7 is restarted in the state where the cage 7 has circulated one extra cycle, the called cage 7 moves to the loading / unloading position. It takes a short time and is efficient.

In the present embodiment, this restart is set to be repeated up to twice, and if the called stop position of the cage 7 is still out of the normal stop position, the operator Although the recovery is performed manually, the number of times of restarting may be set appropriately as needed.

As the normal stop position sensor as the normal stop position detector, any known sensor such as a limit switch, a cam positioner, a proximity switch, a photoelectric tube or the like can be used.

[0036]

As described above, according to the control device of the vertical circulation type multi-level parking facility of the present invention, the normal stop position detector for detecting whether the called stop position of the cage is the normal stop position is provided. When the stopped position of the called cage is not detected as a normal stop position by a normal stop position detector, after circulating a certain amount in the circulation running direction, a control unit for reactivating the calling operation is provided. It is equipped with, and even if the called cage is stopped outside the regular stop position of the loading / unloading position, it is automatically restarted, so it is possible to automatically restore the cage stop position, and It has the advantage of eliminating downtime and improving reliability.

The direction of circulation of each cage is controlled so as to be the shortest moving direction of the called cage with respect to the loading / unloading position, and when the fixed amount is one cage, restarting is performed. There is an advantage that the time required sometimes is short.
