Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator operation control device, and particularly to an operation control device suitable for making it possible to arbitrarily change a specific floor on which an elevator is placed on standby when there is no call.

Conventionally, when commanding or canceling operation control for each floor, a switch or button corresponding to the floor was provided for control. For example, when switching the departure reference floor from the first floor to the second floor, switches corresponding to the first and second floors were installed in the car operating panel or in the elevator machine room. Therefore, as the number of switching floors increases, the number of switches also increases, resulting in an increase in space and cost. Moreover, when trying to change or add switching, it was not possible to easily modify it. On the other hand, due to constraints such as the number of switches installed, it has been impossible to create an operating system that arbitrarily changes the departure reference floor.

The present invention has been made in view of the above, and an object of the present invention is to provide an elevator operation control device that can easily change the specific floor on which the elevator is placed on standby when there is no call.

A feature of the present invention is that by combining an in-car destination registration button and a specific floor registration button provided on the in-car operation panel, the specific floor to which the elevator returns can be specified as the floor on which the above-mentioned in-car destination registration button is turned on. That's the point.

The present invention will be explained in detail below with reference to the embodiments shown in FIGS. 1, 3 to 6, and FIG. In this embodiment, a specific floor cancellation button is provided outside the specific floor registration button, and the specific floor is reset by this cancellation button. However, without providing a cancel button, a specific floor may be set each time a registration button is operated, and the present invention is not limited to this point.

FIG. 1 is a front view showing an embodiment of the in-car driving panel, and the in-car destination registration buttons are shown for the first to fourth floors. In FIG. 1, DP is the driving panel, OB is the door open button, CB is the door close button, and 1C to 4C are the destination registration buttons in the car. Cancel button MSB to cancel the standard floor designation, standard floor changeover switch to turn on when it is necessary to switch the standard departure floor
Confirmation lights L1 to L4 are provided to confirm the designated floor when SW1 and departure standard floor are designated.

HW is the hoistway. Security guard SM takes the basket from the first floor.
Get on the KG and press the destination registration button 2C (No. 1) in the car on the 2nd floor.
After arriving at the 2nd floor, check the interior of the 2nd floor, return to the elevator hall on the 2nd floor, press the hall call button (not shown), board the car KG again, and go to the car destination on the 3rd floor. Consider the case where the user presses registration button 3C, arrives at the third floor, inspects the room on the third floor, and then goes to the fourth floor. When using the elevator in this way, if the starting standard floor is fixed at the first floor, when following the steps described above,
The elevator operates in the order of 1st floor → 2nd floor → 1st floor → 2nd floor → 3rd floor → 1st floor → 3rd floor, etc., making unnecessary movements. In this case, if the departure standard floor is the last call floor and there is no other hall call,
You will be waiting for the elevator on the floor you get off to, so there will be no problem. However, if there is another call, the elevator will remain abandoned on another floor, and the security guard SM will have to press the hall call and wait until the elevator arrives. In order to eliminate such wasted time and wait without getting irritated, the operation control device of the present invention is capable of sequentially switching the departure reference floor as necessary, and as shown in Figures 3 and 3 below.

When the SM looks around the second floor and returns to the elevator hall, it is possible to have the elevator standby with the door open or standby with the door closed, but here we will explain it as standby with the door closed.

When you press the rising hall call button, the car door will open and you will be able to get into the car KG. To change the standard departure floor from the 2nd floor to the 3rd floor, press the Cancel button MSB
Press. As a result, the cancellation button MSB is opened, and the departure reference floor detection relay A2 on the second floor is turned off.

The upward direction operation detection relay DU is turned on, and the elevator is operated from the first floor to the third floor and waits on the third floor. In this way, the security guard SM does not have to use the elevator exclusively, the elevator is operated normally for other passengers, and after use, the elevator is placed in the elevator for the security guard SM.
can be placed on standby on the third floor. This also applies when another floor is designated as the departure reference floor.

As mentioned above, to change the departure standard floor,
Turn on the standard floor selection switch SW1 in advance, and then press the Cancel button MSB, the destination registration buttons 1C to 4C in the car that you want to use as the departure standard floor, and the registration button MRB in that order.You can easily set the departure standard floor. can be changed. Furthermore, any floor can be selected from all the floors and used as the departure reference floor.

In addition, to know which floor the standard departure floor is registered, as shown in Fig. 5, for example, if the standard departure floor is the 3rd floor, use the P-A3 ₂ -L3-H circuit to switch the standard floor for the 3rd floor. Since the confirmation light L3 lights up, you can confirm from this.

As described above, according to the embodiments of the present invention, the standard departure floor can be arbitrarily and easily changed, and inspections by security guards at night, linen service at hotels, and mail delivery by postmen at apartments are possible. In cases such as delivery, driving services can be improved. Furthermore, since the standard floor switching confirmation light is turned on, the departure standard floor can be easily confirmed.

On the other hand, the switches that were conventionally provided for each floor as a means of registering and canceling departure reference floors are no longer required, and moreover, the in-car destination registration buttons 1C to 4C can be used for registration of departure reference floors. Therefore, it can be made inexpensive.

In the above embodiment, in FIG. 3, once registered departure standard floor (return floor) detection relay A
One of 1 to A4 continues to hold itself until the cancel button MSB is operated. On the other hand, in FIG. 4, the normally open contact A1 of these return floor detection relays
₂ to A4 ₂ are connected in parallel to the normally open contacts C1 ₃ to C4 ₃ of the in-car destination registration relays on each floor, and the car call and the equivalent call for returning are in an equal relationship.

Therefore, once the car leaves the return floor due to a car call, it is equivalent to a car call with the return floor as the destination floor, and each time the car service is completed for another car call, the car tries to return to the return floor. This can be said to be optimal for the patrols of the security guards mentioned above.

However, the present invention is not limited to this, and as is well known, the elevator is deemed to be idle after a predetermined period of time has elapsed since the calls to be serviced have been interrupted, and the elevator is therefore not operated to the return floor. It is easy to think of variations such as starting the call, or starting the drive to the return floor when all other calls have disappeared.

Note that FIG. 6 is a circuit diagram showing a modification of the present invention. In FIG. 6, the same parts as in FIG. 3 are indicated by the same reference numerals, and their explanation will be omitted. In Figure 6, the registration button MRB and cancellation button MSB in Figure 3 are removed, and instead, the door open button on the car operation panel PN is used.
The OB and door close button CB were reused and connected as shown in Figure 6. In Fig. 6, SW2 is a registration/cancellation changeover switch, K is a detection relay for switches SW1 and SW2, _K1 is its normally closed contact, R is a cancellation detection relay, and _R1 and _R2 are its Normally closed contact, T is registration detection relay, T ₁ ,
T ₂ is its normally open contact, DOCS is the door opening/closing circuit.

In this case, turn on the departure standard floor selection switch SW1 and the registration/cancellation switch SW2.
-SW1-SW2-K-N circuit turns on detection relay K. By turning on relay K, the normally used door opening/closing circuit DOCS is temporarily disabled. At this time, if you press the open button OB, P-SW1-
Registration detection relay T is turned on by the circuit SW2-OB-T-N. As a result, P-
The departure reference floor detection relay A3 is turned on by the circuit T5- _C32 -A3-N. Further, when the close button CB is pressed, the cancellation detection relay R is turned on, relay T is turned off, and relay A3 is turned off by the circuit of P-SW1-SW2-CB-RN.
Complete registration and cancellation of departure standard floor and switch
When SW2 is turned off, normal operation resumes. In this way, the button can be temporarily opened as a means of registration or cancellation.
Even if OB and close button CB are used, the same effect as above can be obtained.

In addition, although the above-mentioned embodiment describes the case of switching the departure standard floor, the present invention can be applied, for example, when operating with predetermined stopping floors or selecting non-stop floors, such as in a department service. You can apply this idea and get almost the same effect.

In addition, the registration button MRB and cancellation button used in the example
The MSB is not limited to a button, and may be any other item as long as it has an equivalent function.

As explained above, according to the present invention, the return floor can be changed arbitrarily and easily.
This has the effect of improving elevator service.
