Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention 1 (Industrial Field of Application) The present invention relates to a control device for a double bed that can be operated in conjunction with an automatic guided vehicle.

(Prior Art) In recent years, automatic guided vehicles have been put into practical use that transport objects such as heavy objects from one point to another via an arbitrary route.

By the way, in order to use this automatic guided vehicle to transport objects from one place to another between different floors in a building, it is necessary to dock the automatic guided vehicle with an elevator, which is a vertical transportation system in the building. There is. Conventionally, in order to link the automatic guided vehicle and the elevator, the automatic guided vehicle transmits a call signal and a destination floor signal to the elevator, causing the elevator to respond to the calling floor, and then places the automatic guided vehicle in the car at the destination floor. I'm trying to carry it to. In this case, since both the automated guided vehicle and the elevator are moving objects, a complete interlock is established as to whether the automated guided vehicle can be boarded or disembarked from the elevator.

However, if the operation of the elevator is controlled in conjunction with the automated guided vehicle, for example, if the automated guided vehicle issues a call signal to the elevator and the automated guided vehicle breaks down while the Nirebetta is waiting at the called floor, the elevator will automatically You will have to wait for the car to arrive for a long time.

Therefore, elevators are normally used for general passenger transportation and are made to respond only when a call is received from an automated guided vehicle. In this case, general passengers would have to wait in the hall for a long time waiting for the elevator to arrive.

(Problems to be Solved by the Invention) As described above, in the conventional elevator operated in conjunction with an automatic guided vehicle, the self-I! Even if an abnormality such as a breakdown occurs in a guided vehicle, the operation of the elevator is not controlled in such a way that this situation is not taken into account. There was a problem in that operation would not start unless the hall arrived, making it impossible to respond to general hall calls.

Therefore, when controlling the operation of an elevator in conjunction with an automatic guided vehicle, the present invention determines whether or not there is an abnormality in the automatic guided vehicle, and if there is an abnormality, the elevator is immediately sent to a general hall call. Elevator control that can respond
The purpose is to provide equipment.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention works in conjunction with an automatic guided vehicle that transports objects from one point to another via an arbitrary route. In an elevator capable of automatic transportation between different floors, the storage means stores a car call signal and a destination floor signal transmitted from the own vJWi power transmission, and the storage means stores a car call signal and a destination floor signal. A call response means that causes the elevator to respond to the call floor and destination floor when stored, and when the car lands on the call floor or the destination floor and the door is fully opened by the call response means, it is possible to board or alight from the automatic guided vehicle. a transmitting means for transmitting a signal;
operation transition means for shifting the elevator to call operation of the automatic guided vehicle upon receiving a boarding completion signal or alighting completion signal transmitted from the automatic guided vehicle; and a transmission means for transmitting a boarding or disembarkation enable signal to the automatic guided vehicle. and reset command means for giving a reset command to the call response means if the boarding completion signal or the disembarking completion signal is not received within a preset certain period of time.

(Function) Therefore, in the elevator control device having such a configuration, the elevator responds to the call signal from the automatic guided vehicle and the signal from the destination floor, and the car lands on the call floor or the destination floor and the door opens. Even if a boarding or disembarkation ready signal is sent to the automatic guided vehicle after fully opening, if the boarding completion signal or disembarking completion signal is not received from the own lJJm power transmission within a preset period of time, there is an abnormality in the automatic guided vehicle. By determining that there is a call signal and resetting the call signal and destination floor signal, it becomes possible to cause the elevator to promptly respond to a general hall call.

Next, the operation of the elevator control device configured as described above will be described.

First, the case of normal operation of an elevator in conjunction with an automatic guided vehicle will be described with reference to the flowchart shown in FIG. When an automated guided vehicle call occurs, additional registration of general car calls is prohibited, and the automated guided vehicle call is responded to after all responses to already registered calls have been completed. When the automatic guided vehicle 1 transmits a call signal and a destination signal, the elevator first responds to the call signal and opens the door after landing on the called floor. Then, when all the doors are opened, a boarding ready signal is output from the elevator to the automatic guided vehicle 1. When the automated guided vehicle 1 receives this boarding ready signal, the automated guided vehicle 1 moves along the guide tape 8, and when the entry into the elevator car is completed, the automated guided vehicle 1 sends a boarding completion signal to the elevator. When the elevator receives this signal, it closes its door, and after the door is closed, the automatic guided vehicle 1 heads to the destination floor. When the elevator car reaches the destination floor of the automatic guided vehicle 1 and the door is completely opened, an exit enable signal is output to the automatic guided vehicle 1. and,
When the automatic guided vehicle 1 receives this disembarkation enable signal, it starts disembarking from the elevator car, and outputs a disembarking completion signal when dismounting is completed. The elevator doors began to close, and no one else
If there is no call for JW1, it will return to normal operation as a general service elevator.

The above is the normal operation of the elevator in conjunction with the automatic guided vehicle, but the operation of the control circuit shown in FIGS. 2 to 4 will now be described as follows.

In FIG. 2, when a call signal and a destination floor signal are input from the automatic guided vehicle 1 to the elevator, contacts 11 and 12 are closed, and the call floor is stored in the call floor storage circuit 13.
Further, the destination floor is stored in the destination floor storage circuit 14, and the corresponding storage relay 15, 16 is activated by its output. Due to the operation of the memory relays 15 and 16, control power is input to the call direction selection circuit 19 of the automatic guided vehicle through its contacts, and the output of the call direction selection circuit 19 is transmitted to the direction selection relay 24 or 25 works. Therefore, the elevator is sent to its own A11 via an operation operation circuit (not shown). 11 calls will be answered.

When the elevator responds to the call from the automatic guided vehicle 1 and the car lands on the called floor and the door opens, the contacts 33 or 34 close in FIG. Output. Then, when the automatic guided vehicle 1 enters or exits the elevator car, the contact point 31 or 3
2 is closed, a boarding completion signal or alighting completion signal is input to the elevator automatic guided vehicle call operation circuit 35, and when the door closing is completed, the elevator is operated.

In this case, the timing of the transmission and reception of signals between the automated guided vehicle and the elevator is such that the boarding ready signal and boarding completion signal, as well as the getting off ready signal and the getting off completion signal, are completely interlocked, as shown in FIG. Therefore, in either case, the elevator does not start the door closing operation unless it receives the completion signal.

On the other hand, in the abnormality monitoring circuit for the automatic guided vehicle shown in FIG. 4, the optical 'R tube operation switch 41. Even if the normally open contacts 42 of the door full-open relay close together and the contacts 43 or 44 close due to the boarding ready signal or the disembarking permit signal, the automatic transport 1 is restarted within the set time of the reset relay timer 48.
Since the boarding completion signal or the dismounting completion signal is inputted from the terminal 11 and the contact point 45 or 46 opens, it is possible to detect that there is no abnormality in the automatic guided vehicle.

By the way, in the case where the elevator does not receive the boarding completion signal or the disembarking completion signal due to an abnormality in the automatic transport vehicle 1, even though the elevator outputs the boarding completion signal or the disembarkation completion signal to the automatic transport vehicle 111 in the above-described operation process. When this state continues for a period longer than the time set by the reset relay timer 48, the reset relay 47 is activated by the output of the reset relay timer 48. Therefore, since the control power circuit is cut off by opening the output contacts 26 and 36 of the reset relay 47 provided in the control power circuit shown in FIGS. 2 and 3, all signals related to the automatic guided vehicle of the elevator are reset. The elevator will then return to normal operation. As a result, even if there is an abnormality in the automatic guided vehicle, the elevator does not have to wait forever for the automatic guided vehicle to arrive, and after a certain period of time has elapsed, the elevator can immediately respond to a general hall call.

[Effects of the Invention] As described above, according to the present invention, automatic transport between different floors is possible in conjunction with an automatic transport vehicle that transports objects from one point to another via an arbitrary route. In a capable elevator, a storage means for storing a car call signal and a destination floor signal transmitted from the automatic guided vehicle, and when the car call signal and a destination floor signal are stored in the storage means, the elevator is stored in the car call signal and the destination floor signal. a call response means for responding to a floor; a transmitting means for transmitting a boarding or alighting signal to the automatic transport vehicle when the car lands on the call floor or the destination floor and the door is fully opened by the call response means; operation transition means for shifting the elevator to call operation of an automatic guided vehicle upon receiving a boarding completion signal or alighting completion signal transmitted from a car; and a presetting after transmitting a boarding or disembarkation enable signal to the automatic guided vehicle by the transmitting means. and a reset command means for giving a reset command to the call response means if the boarding completion signal or the disembarkation completion signal is not received within a predetermined period of time, the elevator receives the call signal from the automatic guided vehicle and the destination floor. Even if the car responds to the signal and sends a signal that it is possible to get on or off the automated guided vehicle after the car has landed on the call floor or destination floor and the door is fully opened, the automated guided vehicle will not respond within a preset period of time. If the boarding completion signal or the disembarkation completion signal is not received, it is determined that there is an abnormality in the automatic guided vehicle and the above-mentioned call signal and destination floor signal are reset, so the elevator can be used as a general hall call. It is possible to provide an elevator mW control device that can quickly respond.
