Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator door control device.

[0002]

[Prior Art]

 Conventionally, in a luggage elevator, as disclosed in Japanese Patent Publication No. 56-15388, when the loading / unloading time of the luggage is considered to be long, the open / extend button is pressed and a predetermined time, for example, 30 seconds, The door is being extended. Then, when the loading / unloading work of the luggage is completed, the opening extension operation can be released by operating the release button.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, in order to cancel the extension of the door opening, it is necessary to operate the release button and further operate the car call button on the floor desired by the passenger. For this reason, there are problems that the operation is troublesome and that the elevator is stopped until the time when the opening and extension ends until the passenger does not understand the function of the release button, which gives the passenger a feeling of frustration. ..

An object of the present invention is to provide an elevator door control device that can release the door opening extension by a simple operation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a door control for an elevator having a door open extension circuit that keeps the door open for a predetermined time when an open extension button in an operation panel provided in a car is operated. In the device, when at least one car call is registered by operating a car call button in the operation panel while the door open extension circuit is operating, the door open extension release circuit that releases the operation of the door open extension circuit It is equipped with.

[0006]

[Action]

 The present invention is configured as described above, and since the passenger can easily release the door opening / extending by simply operating the car call button in the operation panel, the passenger does not feel frustrated. In addition, the operating efficiency of the elevator will be improved, which will improve the service to customers.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In FIG. 2, 1 is a car and 2 is an operation panel provided on the car. The operation panel 2 is provided with an open button 3, a close button 4, car call buttons 5 to 7, and an open extension button 8.

In FIG. 1, between the power supplies P and N, a contact 3 a that opens when the open button 3 is operated, and a normally open contact 10 Ta (not shown) that opens the door 9 and automatically closes the door 9 after a predetermined time. And a normally closed contact 12b1 which will be described later, and a door opening / closing command relay 11 that issues a door closing command when energized and issues a door opening command when deenergized are connected in series, and contact 3b and normally open contact 10Ta. A normally open contact 14a1 which will be described later is connected between the connection point with and the connection point between the normally closed contact 12b1 and the door opening / closing command relay 11. Here, the normally open contact 14a1 constitutes a door open extension release circuit. Further, a contact 8a of the open extension button 8, a normally-closed contact 13Tb1 to be described later, a normally-open contact 12a1, 12a2, and an open-extension command relay 12 having a normally-closed contact 12b1 are connected in series between the power supplies P and N. And the normally open contact 12a1 is connected in parallel to the contact 8a. In addition, a normally open contact 12a2 between the power supplies P and N, and a timer for setting a time limit for extension of opening, which is a contact 13Ta1 that is closed and opens when a predetermined time (for example, 30 seconds) has elapsed after being energized. A timer 13T having a contact 13Tb1 is connected in series with each other. Further, the contact 4a of the closed button 4 and the detection relay having the normally open contact 14a1 are connected in series between the power supplies P and N, and the contact 13Ta1 and the car call buttons 5 to 7 are operated to call each of them. The normally open contacts 5a1 to 7a1 of a car call registration relay (not shown) that are energized when is registered are respectively connected in parallel, and the normally connected contacts 5a1 to 7a1 connected in parallel are connected in series to form the contact 4a. Are connected in parallel.

Next, the operation of this embodiment will be described.

When the open extension button 8 is pressed, the circuit of P-8a-13Tb1-12-N energizes the open extension command relay 12, and further, when the open extension command relay 12 is energized by 8a, Since the normally open contact 12a1 is closed, a circuit P-12a1-13Tb1-12-N is formed to hold the open extension command relay 12 by itself. By the activation of the opening extension command relay 12, the circuit of P-3b-10Ta-12b1-11-N is opened and the door opening / closing command relay 11 is deenergized, so that the door 9 is opened, and further the door 9 is For example, keep it open for 30 seconds.

When it is desired to end the opening / extending operation during the opening / extending operation, when the closing button 4 provided on the operation panel in the car is operated, the closing button operation detection relay 1 is operated by the circuit P-4a-14-N. 4 is further energized, the circuit of P-3b-14a1-11-N is further formed, the door opening / closing command relay 11 is energized, and the door 9 is closed.

Further, for example, when the car call button 5 is pressed, a car call is registered and the normally open contact 5a1 is closed, so that the P-13Ta1-5a1-14-N activates the close button operation detection relay 14. Then, by the circuit of P-3b-14a-11-N, the door opening / closing command relay 11 is energized to close the door. This is the same as pressing the door close button 4, but normally it is necessary to close the door and then press the car call button twice. The extension operation can be canceled.

[0013]

[Effect of the device]

 According to the present invention, the passenger can easily cancel the door opening / extending operation only by operating the car call button in the operation panel, so that the passenger does not feel frustrated and the operation efficiency of the elevator is improved. Therefore, it is possible to improve the service to users.
