Description

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

The use of self-driving trolleys has been proposed to automatically transport cargo. In hospitals, etc., the food serving table is placed on an automatically traveling trolley, which is then placed on the car of the receiving elevator and transported to each floor. In other words, when you specify the destination floor of the trolley using the destination floor button on the setting board installed in the serving room and press the departure command button, the trolley automatically moves toward the elevator landing. When it is detected that the car has arrived at this floor, 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.

When multiple cages are installed, one specific cage is switched to a trolley for exclusive use.

Therefore, it is necessary to wait until the above-mentioned specific one becomes empty, resulting in a delay in transporting the trolley.

This invention is intended to improve the above-mentioned problems, and when a dedicated operation request is issued, the automatic car is selected to be used for transporting the trolley, and the car is emptied quickly, thereby speeding up the transport of the trolley. The purpose of this invention is to provide an automatic transport device for a traveling trolley.

Hereinafter, an embodiment in which the present invention is applied to a case where five cars are installed will be described with reference to FIGS. 1 to 3. However, Figure 2 is provided in common for Units 1 to 5, and

This is the output of the car, which is the signal to turn off the lights while inside the car.

Next, the operation of this embodiment will be explained.

Assume that the trolley (3) loaded with the serving table (4) is now in the serving room on the first floor. When the staff member specifies the destination floor of the trolley (3) using the destination floor button (not shown) in the serving room and then presses the departure command button (not shown), the trolley (3) will be guided in the direction of travel by the guide line (2). I was guided and headed to the elevator hall. When the trolley (3) arrives at the landing, a car call signal is issued (circuit is omitted). In addition, the trolley (
3) At the same time as the departure of
When closed, the dedicated operation request signal (unit a) becomes rHJ.

On the other hand, when a car call is registered in each car, car call registration signals (71A) to (79A) ----('i'lK
) to (79E) becomes rHJ, and the counter (8
A) to (8E) count the number of registered calls.

Comparator 0α selects the minimum output among the outputs of counters (8A) to (8E). If it were the first machine, only the output (10aA) would be rHJ. Now, NOR game)
(Since all inputs of lφ are “L”, its output is r
It is HJ. Therefore, the scanning pulse (13a)
When becomes rHJ, the output of the AND game (14A) becomes rHJ, the memory (15A) is set, and its output, the dedicated operation permission signal (X5aA) of Unit 1 becomes r
Becomes HJ. Now, the output of NOR gate Q is rLJ
Then, AND gates (14A) to (14E) are closed. When the signal (x5aA) becomes rHJ, the dedicated operation indicator light (17A) lights up to indicate that it is used for the heel (5A) of unit No. 1 - bogie (3). Further, the hall call response blocking circuit (18A) operates, and the car (5A) no longer responds to the hall call Plj. Further, the car call registration blocking circuit (19A) is also activated, and call registration is no longer possible for the car (5A). Therefore, the car (5A) responds to the calls that have been registered up to that point in order, and the car (5A)
The car call registration is canceled as 0 and (5A) answer car calls, and when all car calls have been answered, the car call registration signal (71
A) to (71F,) are all rLJ. Now, N
The output of the OR gate (20A) becomes rHJ, and the output of the AND gate (21A) also becomes rHJ. After 10 seconds, the output (22aA) of the delay circuit (22A)
becomes rHJ, and the car interior light off signal (24aA), which is the output of the OF+ gate (24A), becomes rs. Since this is where the trolley (3) is placed, care must be taken to ensure that no one gets on it.Also, since the exit direction (22aA), that is, the dedicated operation command signal is rHJ, when the trolley (3) gets on the trolley (5A), The car (3A) travels to the designated floor.

When the car (5A) arrives at the designated floor, if the staff releases the dedicated operation request device (the river), the dedicated operation request signal (ll
a) becomes rLJ, and the output of NOT gate 021 becomes “
The memory (15A) is reset and the output (15aA) becomes "H". This will return to normal operation.

The operation when another corner is selected by the comparator (lO) is also as follows.
It's exactly the same.

Note that this method is applicable regardless of whether a plurality of cars are managed in groups or if a plurality of cars are installed as a single type.

It is also possible to implement as follows.

((7) In a group control elevator that displays cars assigned to one hall call at a landing, the dedicated car selects the car with the lowest sum of its assigned call and car call.

(a) When there are multiple cars with the same number of car calls and Qs, select the car that can arrive at the floor where the trolley (3) is located quickly after completing responses to all car calls.

(Rough Select a place that is difficult for people to use, that is, a place far from the entrance of the boarding area.) Do not artificially generate or eliminate the exclusive operation Ansui I No. 5 (lla), 3) It is generated when the destination floor is specified, and is made to disappear when the specified floor is reached, and it is made to occur and disappear after the BI fixed time.

(b) When the dedicated operation permission signal (lla) becomes rHJ, all car calls for the selected car are canceled and the passengers in the car are forcibly alighted.0<fj) Mechanical guide devices such as guide rails, optical guide devices using white lines or stainless steel tape can be used as running direction guide devices! Use.

As explained above, in this invention, when the dedicated operation request device is activated, at least the car with fewer car calls registered among the calls to which the car should respond is selected as the car for use in the automatic traveling trolley, so the car can be emptied quickly. This can speed up transportation by trolley.

Furthermore, since the lights of the car selected for trolley transport are turned off (C), passengers can be prevented from getting into the car for transporting the trolley.
