Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for automatically transporting an unmanned vehicle.

BACKGROUND ART In hospitals, factories, etc., devices are in practical use that transport unmanned luggage carriers to predetermined floors using elevator cars. That is, when a destination is designated to the unmanned vehicle using a push button or the like, the unmanned vehicle automatically travels to the elevator landing and waits in front of the elevator landing door. Here, the landing call for this floor is registered and the car is called. When the car arrives and the door opens, the unmanned car automatically moves into the car and the car heads towards the designated floor. When the car arrives at the designated floor and the door is opened, the unmanned car will automatically get off the car and drive to the designated location. These operations are well known. It goes without saying that the above-mentioned elevator can also be used for normal elevator operation in which a person presses a call button to call a car, and then presses a destination button inside the car to go to a desired floor.

However, when a person comes to the elevator hall to use an elevator, it is impossible to know the status of the unmanned car, such as whether the unmanned car is inside the car or whether the unmanned car will get off the car when the car arrives. Therefore, there is a risk that humans and unmanned vehicles may come into contact or collide.

This invention improves the above-mentioned problem by notifying the passenger of the relative relationship between the unmanned car and the elevator car, thereby informing the user of the situation of the unmanned car and preventing the risk of contact between people and the unmanned car. An object of the present invention is to provide an automatic transport device for an unmanned vehicle.

Next, the operation of this embodiment will be explained.

First, an overview of the operation of this embodiment will be explained with reference to FIG.

When the destination is specified for the unmanned vehicle (5) by the unmanned vehicle destination command device (■]) (details omitted), the unmanned vehicle control circuit (c)
(Details omitted) operates to drive the wheel electric motor (A) and control its speed, and the unmanned vehicle (5) moves along the guide line (
4), for example, run to the elevator landing on the first floor. When the unmanned vehicle (5) is detected by the unmanned vehicle detection device (1A), the priority determination circuit (c) (unmanned vehicle transport detection relay (
Destination registration circuit (c) (consisting of destination registration relays (1H) to (3H) and their contacts) via the handcart transport detection relay (9) and their contacts)
The destination will be registered. This destination registration causes the elevator control circuit (c) (details are omitted) to operate, controls the hoisting motor (c), and calls the car (6).

When the unmanned car (5) gets on the heel (6), the destination is registered and the car (6) travels to the specified destination floor. Further, when the person operating the handcart presses the call button (IB), the destination is registered in the same manner as described above, and the basket (6) is called.

Then, when the call button (IB) is pressed or the unmanned vehicle (5) is detected by the unmanned vehicle detection device CIA), the priority determination circuit operates, giving priority to that call and calling subsequent calls. to prevent Also, when the call button (and) is pressed, a command is given to the unmanned vehicle control circuit (a), and the unmanned vehicle (
5) to stop outside the designated area. During the above operation, the relative relationship detection circuit (c) detects the relative relationship between the unmanned vehicle (5) and the heel (6), and when the unmanned vehicle (5) uses the heel (6), the alarm ( When the unmanned vehicle (5) exits from the heel (6), the alarm (1) is used.
E) shall be notified in the same manner.

Next, details of the operation will be explained with reference to FIGS. 10 to 4.

When the DC power supply (g) and (→ are turned on), the time relay for limiting the number of registrations (7) is energized, and the contacts (7a) to (7e) are closed.

Now, assuming that the car (6) is waiting on the third floor with the door closed, the door fully closed detection relay contacts (10a) to (1oe) are closed, and the contacts (lOf) and (log) are open. There is. Here, when the unmanned j' [(5) whose destination is specified as the second floor runs to the landing on the first floor, the destination command relay contact on the second floor (2
Ga) to (2Gd) are closed. Unmanned car (5) is 1
When entering the designated area of the factorial place, the unmanned vehicle inspection heavy equipment @ (1A) operates, and the unmanned vehicle detection relay contacts (IAa) ~ (1Ac)
is closed. When the contact ("IAa) closes, (→-(
lAa) -(9f)-(loc) -('7c)-(
lH) - (→ circuit connects the 1st floor destination registration relay (lH
) is energized and maintains itself by closing the contact (IHa). Also, by closing the contact (lAb), (g) - (2
Gb)-(Co-Ab)-(ta)-(9g)-(s)
- (In the circuit →, the unmanned vehicle transport detection relay (8) is energized and self-holds by closing the contact (8e). Also, since the contacts (8a) to (8C) are open, the first floor... The call buttons (IBa) to (3Ba) on the 3rd floor become insensitive and prevent the handcart transport operation.Also, since the contact (Bf) is closed, the in-use alarms (LD) on the 1st to 3rd floors are disabled. (3D), for example, notifies that "unmanned vehicle is in use" and notifies that transport of the handcart will not be accepted.

On the other hand, since the contact (IHI)) is open, the time relay (
7) returns after a certain period of time, and contacts (7a) ('7e) open.

By energizing the destination registration relay (IH) on the first floor, the destination call on the first floor is registered and the car (6) is called to the first floor. When the car (6) reaches the first floor, the position detection relay contact (1, Tb) is closed. When the car (6) stops, the door starts to open, and the door fully closed detection relay contact (lOd) opens.

At this time, since the stop command relay contact (11a) is open, the destination registration relay (1H) on the first floor is deenergized, the contact (1aa) is opened, and the contact (IHb) is closed. Now, the time relay (7) is energized again. Also, since the contact (1of) is closed, (T) - (lAc) - (1
-(1ot)-(]:1-(-) circuit energizes the unmanned vehicle destination registration timing determination relay 0, and maintains itself by closing contact C13d). In addition, the contact (1
3a) to (13c) are closed. When the door is completely opened, the unmanned vehicle (5) enters the base (6), and when the vehicle stops, the door begins to close. When the door is completely closed, the door fully closed detection relay contact (lOb
) is closed, (→-C2Ga) -(13b)-(9c
) - (10b) - ('7b) - (2H) - (By the circuit →, the destination registration relay (2H) on the second floor is energized and self-retained by closing the contact (2Ha). (
2Hb) is opened, the time relay (7) returns after a certain period of time, and the contacts (7a) to (7c) are opened. By energizing the destination registration relay (2H), the destination call for the second floor is registered, and the car (6) runs toward the second floor. Basket (
6) approaches the second floor, the stop command relay contact (11b)
When the unmanned vehicle destination registration timing determination relay (13) is deenergized, the contacts (13a) to (13d) are opened. At this time, the position detection relay contact (2C) on the second floor is closed. Therefore, (→-1Ga) -(2IC) -(2E
) - ( → circuit, the departure alarm (2E) on the 2nd floor notifies, for example, "An unmanned car is leaving", and the unmanned * from the car (6)
(5) announces that it is coming down.

When the car (6) stops, the door starts to open, and the door fully closed detection relay contact (lOd) opens, so the destination registration relay (2H) on the second floor is deenergized, the contact (2Ha) opens, and the contact ( 2Hb) is closed. Now timed relay (7)
is energized. In addition, the door fully closed detection relay contact (10a)
~ (1OC) + (10e) will be open, so 1st floor~3
Floor call buttons (1Ba) ~ (3Ba), (IBb) ~
(3Bb) becomes insensitive and prevents the handcart transport operation.

When the door opens fully and the unmanned car (5) gets off the heel (6),
The unmanned vehicle detection device (2A) operates, and this operation opens the destination command relay contacts (2Ga) to (aGd') on the second floor (circuits are omitted). By opening the contacts (2Gb) and (2GC), the unmanned vehicle transport detection relay (8) is deenergized.
Contacts (8a) to (8d) are closed, and contact (8e) is open.

When the contact (2Gd) is opened, the vehicle exit alarm (2E) is turned off.

When the unmanned vehicle (5) leaves the designated area, the unmanned vehicle detection device (
2A) returns, and the door begins to close due to this operation (circuit omitted). When the door is closed, the door fully closed detection relay contact (
10a) to (10θ) are closed. Now on the 1st floor again~
3rd floor call button (IBa), (IBb)
~(3Bb) becomes valid and can service the next handcart or unmanned vehicle (5).゛Also, contact (IOg)
is opened, but since the contact (8f) is already open at this time, the busy alarms (1D) to (3D) on the 1st to 3rd floors are
turns off and notifies you that the above service is available.

Next, suppose that the car [6] is waiting on the third floor with the door closed, and the person operating the handcart presses the call button (lB) at the landing on the first floor. By closing the call button (lBa), (+L-(

(3D) is activated and indicates that the handcart will not be accepted.

On the other hand, when the handcart transport detection relay (9) is energized, it sends an entry prohibition signal to the unmanned vehicle (5) to stop before entering the predetermined area (although it is transmitted wirelessly).
(details omitted). When the destination registration relay (1H) on the first floor is energized, the toe (6) runs as described above and when it reaches the first floor, the door opens. Now, put the handcart into the basket (6) and press the destination button (2F) for the second floor inside the basket (6). (
G) -1Fa) -(7b) -(2n) -(→ The destination registration relay (2H) on the second floor is energized and self-holding.The door begins to close, and the door closes completely. The fool (6) runs, and when it reaches the second floor, the door opens. Once the door is opened, the handcart is lowered from the fool (6).

When you press the door close button (2C) on the second floor landing,
Since the floor position detection relay (2nd a) and travel relay contact 0 are open, the handcart transport detection relay (9) is deenergized, contacts (9a) to (9g) are closed, and the contact (9h
), (91) are open. Now the in-use alarm (1
D) to (3D) are turned off. Also, door close button (2C)
When pressed, a well-known door closing circuit (not shown) is activated and the door begins to close. When the door is completely closed, the door fully closed detection relay contacts (10a) to (10e) are closed, and the call buttons (IBa) to (3Ba') for the first to third floors are enabled. Further, the contact (log') is opened.

Note that it is also possible to implement as follows.

(To) In addition to the in-use alarms (], D) to (3D) and departure alarms (lE) to (3E), notifications that provide even more information such as the presence or absence of luggage and the presence or absence of people in use. Use a vessel.

(b) Each of the above-mentioned alarms uses automatic broadcasting using tone synthesis, etc., or a buzzer, etc. instead of indicator lights. Also, use them together.

(X) Each of the above-mentioned alarms are installed not only in the boarding areas, but also in unmanned vehicles (5
) or installed on people's paths.

2) If the unmanned vehicle (5) is to be operated during a specified time period, the time shall be announced.

As explained above, in this invention, the relative relationship between the unmanned car and the elevator car is detected and the contents are reported to the hall, so that the elevator users are informed of the situation of the unmanned car, and the relationship between people and the unmanned car is The danger of contact can be prevented.
