For this purpose, a wagon that stores meals, a battery-powered automatic guided vehicle (hereinafter referred to as a transportation vehicle) that automatically transports the wagon, and an elevator car equipped with an automatic loading/unloading device for luggage are used.

That is, the wagon containing the food is transported to the elevator landing by a transport vehicle, and when the car arrives, it is carried into the car by an automatic loading/unloading device inside the car. The basket then travels to the designated floor, where the conveyance vehicle inside the basket is transported to the landing by the automatic loading/unloading device, and the meal delivery procedure is thus completed. In addition, in the case of returning various types of tableware, the procedure is the reverse of the above, and the wagon containing empty tableware is transported to the elevator landing of that floor, loaded into the car, and the car travels to the first floor. When the basket arrives on the first floor, the wagon is carried out to the landing,
It will be transported to the cooking room by a transport vehicle.

By the way, in order to call the transport vehicle that transports the wagon that has been taken out to the landing on the first floor, a detection device such as a photoelectric device is installed at the landing on the first floor, and this detects the wagon and calls the transport vehicle. I'm trying to send a signal. Therefore, the conveyance vehicle will be called after the above-mentioned detection is performed, and there is a risk that the arrival of the conveyance vehicle will be delayed.

This invention is intended to improve the above-mentioned problem, and eliminates the delay in transportation time by emitting a call signal for the conveyance vehicle before the elevator car loaded with luggage arrives at the destination floor. The purpose of the present invention is to provide an automatic cargo transport device that enables the following.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 to 5 are the floors of the first to fifth floors, 6 is the elevator hoistway, 7 is the elevator car located in the hoistway 6, 8 is the counterweight, and 9 is the car 7 and the counterweight 8. 10 is a drive sheave for the hoist installed in the elevator machine room, 11 is a junction box installed in the middle of the hoistway 6, and 12 is a cable suspended between the car 7 and the junction box 11. moving cable,

A wireless transmitter, 16 is a wagon located on the 4th floor 4 and 1st floor 1 and stores luggage such as tableware, 16a is a wagon 16
16b is the same wheel, 16c is the destination floor name written on one side of the wagon 16, 16d is an indicator piece movably provided in front of the destination floor name 16c, 17 is the first floor 1 The direction of travel is guided by guide wires (not shown) etc. buried in the floor of the vehicle, and the vehicle automatically travels between the galley 18 on the first floor 1 and the elevator landing.
A transport vehicle 19 having a function of automatically transporting the wagon 16 is provided on the first floor 1 and has a wireless transmitter 15.
An antenna 20 is connected to and transmits the wireless signal to the transport vehicle 17, and is provided in the car 7. When the wagon 16 is in the car 7, the antenna 20 determines the position of the indicator piece 16d using a barcode reader, reed switch, laser scanner, etc. A well-known wagon destination floor reading device 20a to 20e reads destination signals that become "H" when the first to fifth floors are indicated by the output of the reading device 20, and 21 becomes "H" when the car 7 is running. 22 is a door opening command signal that becomes "H" when the door is stopped; 23 is a door closing completion signal that becomes "H" when the door is closed; 24 to 26 are
AND gate, 27 is an RS flip-flop (hereinafter referred to as memory), and 28 is a monostable element whose output becomes "H" for a certain period of time when the input becomes "L".

The car 7 has two entrances and exits facing each other, and is equipped with an automatic loading/unloading device (not shown) such as a fork, a conveyor, and a dolly.

Next, the operation of this embodiment will be explained.

To store the used dishes on the 4th floor 4 in the wagon 16 and set the destination to 1st floor 1, place the instruction strip 16d at the 1st floor position of the destination floor name 16c and place it at the landing on the 4th floor 4. do. 16 wagons at platform 4 on the 4th floor
When it is detected that the car 7 has been placed (the detection device is not shown), the hall call for the 4th floor 4 is registered, and the car 7 is called to the 4th floor 4 by the operation of a well-known elevator control circuit (not shown). . When the car 7 arrives at the fourth floor 4 and the door opens, an automatic loading/unloading device inside the car 7 operates and the wagon 16 is loaded into the car 7. Here, the reading device 20 reads the instruction piece 16.
It is read that the position d is on the first floor 1, and the destination signal 20a for the first floor becomes "H". This signal 20a
becomes a call signal for the transport vehicle 17, which is sent to the wireless transmitter 15 via the moving cable 12, the connection box 11, the signal line 13, and the control panel 14,
9 to the transport vehicle 17. Transport vehicle 1
At step 7, the call signal is received (the receiving device is not shown), and the conveyance vehicle 17 automatically travels to the elevator landing on the first floor.

On the other hand, the destination signal 20a is treated as a car call for the first floor, and when the car 7 closes its door and descends, stopping at the first floor 1, the running signal 21 becomes "L". Now, the output of the AND gate 24 becomes "H". When the door opening command is issued, the door opening command signal 22 becomes "H".
Therefore, the output of the AND gate 25 becomes "H", the memory 27 is set, and its output Q becomes "H". When the door is fully opened, the wagon 16 is lowered to the landing on the first floor 1 by an automatic loading/unloading device. Thereafter, when the door is closed, the door closing completion signal 23 becomes "H", the output of the AND gate 26 becomes "H", the memory 27 is reset, and the output Q becomes "L". As a result, the output of the monostable element 28 becomes "H" for a certain period of time, and as in the case of the destination signal 20a, a transport command for the wagon 16 is transmitted from the wireless transmitter 15 to the transport vehicle 17 via the antenna 19. Ru. In response to this command, the transport vehicle 17 is coupled to the wagon 16 and automatically transports it to the cooking chamber 18.

In the example, a wagon 16 is transported from the fourth floor 4 to the first floor 1.
In the above example, the wagons 16 are transported from the first floor 1 to each floor 2 to 5, and the transport vehicles 17 are also arranged on each floor 2 to 5, and the wagons 16 that are unloaded at the landing are automatically transported. It is clear that this can also be applied to cases.

Note that it is also possible to implement as follows.

(A) When the transport vehicle 17 transports the wagon 16 to the elevator hall, the call signal for the car 7 is similarly emitted during the journey.

(b) Applicable when there are a large number of transport vehicles 17 and cages 7.

(c) Applies to general cargo transportation other than meal transportation.

(d) Applicable to cases where the transport vehicle 17 is used to transport between multiple cars 7.

(E) A plurality of transport vehicles 17 and cages 7 are both running,
These are applied to group control.

(F) Use dumbwaiters instead of elevators.

(g) To guide the traveling of the transport vehicle 17, use an optical type, a gyro compass, etc. in addition to a guide wire, or use a mechanical guide rail.

(H) The destination floor of the wagon 16 is configured to be set by a switch at the landing.

(k) When there are a plurality of transport vehicles 17 and cars 7, a call for the car 7 or a call for the transport vehicle 17 is generated so that the arrival time of the car 7 and the arrival time of the transport vehicle 17 match.

(J) The destination of the wagon 16 is not only the floor,
A destination (for example, the cooking room 18) is set and transmitted wirelessly to the transport vehicle 17.

(S) As a signal transmission means to the carrier vehicle 17, in addition to radio, guided radio, optical communication, etc. are used.

As explained above, in this invention, before the elevator car loaded with luggage arrives at the destination floor, a call signal for the transport vehicle is issued and the transport vehicle is called to the landing, so that the transport time is reduced. can be shortened.
