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.

In hospitals, etc., the food delivery table is placed on an automated trolley, which is then placed on the elevator car for delivery 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 position where the trolley stops when it arrives at the elevator landing is usually set just before the landing door in order to speed up the boarding of the car. As a result, the trolley gets in the way of passengers getting on and off the elevator, sometimes creating a sense of danger.

- In IQ, when a person and a trolley share a car in a cargo elevator, a car that does not move for a specified period of time (until the person in the car gets off) after the cart issues a request to use the elevator will move the car. Not available.

During this time, people who try to get out of the car get in the way of the trolley, and people who are suffering from a medical condition are at risk of colliding with the trolley.

This invention improves the above-mentioned problem by changing the position of the strain force "when a person is present" in the car (from 1st to 0th stop of the bogie) to improve the safety of the person inside the car or the person getting off the car. An object of the present invention is to provide an automatic transport device for an automatic traveling trolley.

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

In the diagram, (1) is the floor leading from the serving room to the elevator landing;
(2) is a guide wire buried in the floor (1) that connects the serving room and the elevator hall and creates a magnetic field through low-frequency current; +3
1 is an automatic traveling trolley whose traveling direction is guided by detecting the magnetic field of a guide wire (2), and (4) is a trolley (3).
(5) is the elevator car, (6) is the elevator landing floor (11) and when energized, the trolley +31 is placed just before (5) (i.e. the elevator landing door). (not shown) A first stop command device/device consisting of a coil that issues a command to stop directly (1J'iJ), (7) is located further away from (5) than the first stop command device (6). The second stop command device installed at (81) to (
89) When a car call is registered at a car call registration signal, the signal becomes "H", and (91) to (98) are chestnut signals that become rHJ when an upbound call is registered at a landing on the 1st to 8th floors. The call registration signals (11, 1) to (119) are respectively (
5) is on the 1st to 9th floors, the car position t1 signal becomes rHJ, (1,21) to (129), (131) to (1
38), (1423 to (149) are AND gates,
06) to (17) are OR gates, (18+Lt and (
5] becomes rl when driving uphill, (1
9) is also a downbound signal that becomes 1-H when driving downhill, and (a) when Hakato (5) is full, it changes to "I(").
full signal, (2υ, (to) is an AND gate, (a) is an OR gate, (c) and when (5) completes closing the door, "H"
Door closing completion r signal that becomes J, (to), (4) is R-S flip 70 knob (hereinafter referred to as memory), (a) is NOT gate, I is OR gate, (28a) is the output of car +51 This is a command signal to stop the machine. Note that the trolley (31) is provided with a coil that engages with the command side 61 and +71 on the second stop side and receives a stop command, but is not shown.

Also, 8r! The circuits shown in Figure 2, except for the first, f, and second stop command devices (6) and +71, are installed in the grating panel of the elevator machine room.

Next, the operation of this embodiment will be explained.

Now, the trolley +31 loaded with the Hd distribution stand (4) is on the first floor.
/Assuming that the call signal for car +51 is emitted as you approach the Beta landing, the up call registration signal for the first floor (91)
becomes rHJ (the circuit is omitted. The same applies hereafter).

On the other hand, if there is no person in the car (5) and the car is in the process of descending due to the downbound call, then the car call registration signal (8
1) to (89) are all rLJ, so it is an AND game)
The outputs of (121) to (129) are all “I, J, O
The output of R gate (10 is also rJ. Therefore, memory (c) is not set and its output is rLJ, NO
The output of the T gate (A) becomes rHJ, and the first stop command device (6) is energized. Therefore, when the bogie (34) travels to the landing and the receiving coil engages with the first stop command device (6), the bogie (3) stops just before the landing door as shown in Figure 1. .The car (5) descends and approaches the first floor (IG) output also becomes rl.At the same time, the car (5)
Since the operating car is switched to the up direction, the up direction signal (18) becomes "H-1".And if the inside of the car (51 is not @ member), the 7174 R signal (1) is rLJ. , the output of AND gate υ becomes “H”, and O
The output of the R gate (c) also becomes "H". With this, the memory (4) is set, its output becomes rHJ, and the stop command signal (28a), which is the output of the OR gate (c), becomes rHJ.
aJ, and the car (5) moves to the first floor by 1.1%, +h. In this case, since there is no person in (5) mentioned above, the trolley + 31 digit 1d is appropriate, and Ii
You can board the train (5) immediately. When the car door (not shown) completes closing, the door closing completion signal (c)
``HJ'', the memory (to) is reset, and the stop command No. 1d (2sa) Tit r'LJ becomes.Now, Kako (5) departs with the opening force 1 for the specified 1 time.

Next, assuming that there is a person in the car (5) and a car call is registered, the car call registration signals (81) to (89)
1. Since one of them is "H". Any one of AND gates (121) to (129) becomes "H".

Therefore, the OR gate (the output of the field becomes rHJ, the memory (c) is set, and its output becomes IH), and the second stop command device (7) is energized this time. 31 runs to the landing, and when the above receiving coil engages with the A↓2 stop command device +71, the bogie +31
The train stops at rik 1α, which is further away from the landing door than the position of the bogie (3) (see Figure 1). Also, when the call signal of Kato (5) is issued by the trolley (3), this is 1 p
The registration signal (91) is not treated the same as the uplink call of '4.
is l-HJ and f,C. 7J1 Go (5) went downstairs to 11
When approaching Satoshi, an AND gate (1
31) becomes "H", the OR gate (the national output also becomes "H" and is stored in the memory) is set, and as mentioned above, the stop command signal (28a) becomes rHJ, and the car (5
) will stop at the first floor. At this time, cart +31 is stopped at 1d, which is far from the heel (5)), and the car (
5) There is no problem with the person inside salivating.

The subsequent operations are as described above.

Note that it is also possible to carry out the following procedure.

(7) When stopping the trolley (3) away from the landing door,
The number 10 on the landing door should be on the side instead of J.

(a) The trolley (31) is made to run to the landing after confirming (1□61) that there is no one in the car (5).

(tsu) Nmi and (5) P at the trolley (3) or the platform.
Displayed in the number.

(:→ There are two entrances and exits at the front and back of the car (5), with -1000 being the entrance for the trolley (3) and the other being the entrance for people.

0) If the negative part in 51 or the car name is used interchangeably, and there is a person in the carton (5), regardless of the year of the person's ride, '
Car B t: (l i;j Stops at a position t.1 away from the landing door.

ψ) 'i'5 Ij, .' 131 is always stopped just before the landing door, and after detecting that a person gets off the car (5), the trolley +31 is moved back fρ from the above position and stopped.

((1) As a guide system for the traveling force of the truck (3), a mechanical guide system using guide rails', q. or an optical guide system using white lines or stainless steel tape is used.

(ri) Applicable for transporting cargo in buildings and factories other than hospitals.
