Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for automatically transporting an automatically traveling trolley using an elevator.

The use of self-driving trolleys has been proposed to automatically transport cargo. At the hospital, the food delivery table is placed on a self-driving trolley, which is then placed on the arrival elevator's car and transported to each floor. That is, when the destination floor button of the trolley is specified using the destination floor button on the destination floor setting panel installed in the serving room and the departure command button is pressed, the trolley automatically travels toward the elevator landing. When it is detected that the trolley has arrived at the landing, an elevator call signal is issued and the car is called to this floor. When the car arrives at the landing, the trolley will board the car and the car will automatically travel to the designated floor.

・ However, the arrival envelope. In the evening, people are also using the trolley, so there is a danger that the trolley may get on top of someone else. To prevent this danger, when a trolley uses an elevator, the staff first confirms that no one is on the elevator before switching the elevator to dedicated operation for transporting the trolley. Therefore, not only does it take time υ1j to change the driving mode, but there is a risk that a person may accidentally get into the car and collide with the trolley.

This invention is intended to improve the above-mentioned problem, and when a predetermined condition is met, it automatically issues a signal requesting exclusive use of the elevator for the bogie, and also notifies this to the hall or inside the car, thereby making it easier to switch to exclusive operation. It is an object of the present invention to provide an automatic transport device for an automatic traveling trolley that is capable of preventing people from entering the vehicle.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the diagram, 0) indicates the transfer from the serving room to the elevator landing, (
3) is drunk 8! (4) is an automatic traveling trolley that travels with the direction of travel being guided by the presence of the vehicle (1) in the number.
3) is a serving table that is automatically loaded, (6) is an elevator car, and (7A) to (7N) are provided in a serving room, and the time to start transporting the trolley (5) is set by the combination of opening and closing. Switches (8A) to (8N) are also switches for setting the time at which transportation is complete, (91Fi is a digital clock that emits a time signal, +101, and flll is for input. The value determined by the combination of human power N is the value of input X. A coincidence detector whose output becomes "Hj" when it matches, and "L" otherwise. 031 Kakato (6) is a hall call response prevention circuit that prevents the car from responding to hall calls, (14) is a trolley use forced input switch installed in the serving room, (+m is O
R gate, (161) to (1f59) Car call registration signal that becomes rHJ when a car call is registered with the destination floor buttons (not shown) for the 1st to 9th floors in Hagato (6), (171
) to (1'7B) are landing up call registration signals that become rHJ when an up call is registered at the landings on the 1st to 8th floors, (182
) ~ (189) Fi indentation (2nd floor to 9th floor landing call registration signal, 091 ~ IIFiOR gate, location is AND
The dedicated operation indicator light (8) is installed in the landing area or at the gate (6), and the output (24a) (dedicated operation command signal) is "H", and when the input becomes rLJ, the output (24a) immediately becomes rLJ. A delay circuit, or NOR gate, is a delay circuit similar to the delay circuit example (the setting time is 1 minute), and (me) is an OR gate. gate, (27a) is an OR gate (
The output of 2'71 is a signal to turn off the lights while inside the car. In addition,
In FIG. 2, everything except those specified is provided in the control panel installed in the elevator machine.

Next, the operation of this embodiment will be explained.

Now, the transport start time setting switches (7A) to (7N) are set to 1.
At 1:30, the transportation end time setting switch (8/',)
~(8N) is assumed to be set to 12:00.

When the digital clock (9) reaches 11:30, the output of the coincidence detector (lO) becomes 1d rHJ, and the memory (12
1 is set, and the dedicated operation request signal (12a) becomes "old." Now, the hall call response blocking circuit (13) is activated, and after 1,137 (6) does not respond to the hall call, and the car I started servicing as many people as I wanted.

Meanwhile, the trolley (3) loaded with the serving table (4) is in the serving room on the first floor, and the staff member presses the destination floor button (not shown) in the serving room.
When you specify the destination floor of the trolley (3) by and then press the departure command button (not shown), the trolley (3) moves along the guide line (
2) will guide you in the direction of travel and head towards the elevator hall. When the trolley (3) arrives at the landing, a car call signal is issued (circuit is omitted).

Now, when the car (5) completes responding to the call to Tenka 1, the car call registration signals (161) to (169) all become rLJ, so the output of the OR game Qp; becomes rLJ.

At this time, since the output of the OR gate (15) is rHJ, the output of the ANDNO gate becomes rHJ, the dedicated operation indicator light (231) lights up, and the car (6) is replaced by the trolley (3).
to indicate that it is used for A N D gate □□
When 1" has passed for 10 seconds after the output of □ reaches rHJ, the dedicated operation command signal (24a) which is the output of the delay circuit 24s
becomes rHJ, and from then on, Kato (6) will be used exclusively for transporting trolley (3) and will respond to calls at the designated destination floor. In addition, the car interior lights out signal (2) a), which is the output of the OR gate, becomes rHJ, and the lights (not shown) in the car (6) are turned off, preventing people at the landing from getting into the car (5). Please give me a warning.

When the digital clock (9) reaches 12:00, the output of the coincidence detector (111) becomes "H", the memory θ2 is reset, and the output (12a) becomes rLJ. With this, normal operation will resume and the basket will be able to impersonate people.

Even outside of the above set hours, the table use forced input switch (
141 is fully closed. If 10 seconds pass after the car call disappears, the dedicated operation command signal (24a) becomes "H", and the carriage (3i) can be transported by the car (5).

In addition, car call registration signals (161) to (169), up call and down call registration signals (1'71) to (17
B), (182) ~ (189) Gashe-Cr L J
Then, the outputs of OR gates θ9) to (21) are all rI, J, and the output of NOR gate θ is drHJ
After 1 minute, the output of the delay circuit (2f) becomes rHJ. In this case, the lights inside the car are turned off and the Buddha sign (z7a) Ir
ArHJ occurs, the lighting inside the car goes out, and the car (61V
It enters hibernation state.

Note that it is also possible to implement as follows.

(7) The dedicated operation request signal (12a) is generated when it is detected that the trolley (3) has arrived at a predetermined position.

(b) During dedicated operation, if the operation of the trolley (3) is interrupted or if the trolley (3) breaks down, normal operation will be resumed.

(■ If carts are installed, press the designated one to switch to exclusive use of cart (3).

(-r) When the dedicated operation request signal (12a) becomes "H", subsequent call registration is blocked.

(2) Even when the car is in dedicated operation, the lights inside the car are left on.

(Effectiveness: As an internal device for directing the running force of the trolley (3), use a mechanical guide system using guide rails, etc., or an optical guide system using white lines or stainless steel tape.

(4) Time setting switch (7A) to (7N), (8A)
~(8N) is replaced with one based on frograno processing on an electronic computer.

As explained above, in this invention, when a predetermined condition is met, such as when a preset time arrives or when the trolley comes to a fixed position Qi, a dedicated operation request signal necessary for loading the trolley onto the car is issued. At the same time, this is announced at the landing or inside the car, so switching to dedicated operation can be done quickly, and it is possible to prevent people from boarding the car, thereby increasing safety.
