Description

Description: TECHNICAL FIELD The present invention relates to a control device for a luggage elevator.

[Conventional technology]

To carry luggage carried by a transportation vehicle such as a forklift into the luggage elevator, the cargo worker stops the transportation vehicle at the landing, then exits the vehicle and operates the hall call button. It was necessary to wait for the arrival of the car, and when the car arrived, operate the door open button to open the elevator door.

When the cargo operator who has opened the elevator door and returned to the transport vehicle operates the transport vehicle to carry the luggage into the car, the transported luggage is loaded into the car.

On the contrary, when carrying out luggage from the luggage elevator,
After performing the same operation, the cargo worker loads the cargo from the car into the transportation vehicle and carries it out.

In both the above-mentioned loading and unloading operations, it is a burdensome work for the cargo handling operator to get off the transportation vehicle and operate the hall call button and the door opening button.

Therefore, in Japanese Utility Model Laid-Open No. 52-160962, in order to reduce the burden on the cargo operator, the cargo operator can call the car to the hall while the passenger is still on the transportation vehicle. Luggage elevator controls have been proposed.

According to the luggage elevator control device according to this proposal,
When the car is called, the cargo worker does not have to get off the transport vehicle, and the car is automatically called, so that the load on the cargo worker is significantly reduced.

[Problems to be solved by the invention]

As described above, according to the proposed luggage elevator control device, the cargo worker uses the transport vehicle to carry the luggage into the luggage elevator or to carry the luggage without calling the car. Cargo can be unloaded from the elevator.

However, in the control device for the luggage elevator according to the above-mentioned proposal, the cargo handling operator descends from the transport vehicle and operates the door opening extension device provided in the luggage elevator to arrive at the cargo elevator before starting the cargo handling work. It is necessary to keep the elevator door open.

In addition, when the operation of the door opening and extending device is not completed at the end of the cargo handling work and the door is still expected to be in a considerably opened state, the cargo handling worker operates the door opening and extending device for other users. It needs to be released.

Furthermore, in cargo handling work that uses a forklift with a load at the tip, the sight of the cargo operator operating the forklift is obstructed by cargo handling, so the tip of the forklift is pushed into the elevator door during operation. Accidents that hit the elevator door and bend it are likely to occur.

The present invention has been made in view of the present situation of the above-described control device for a luggage elevator, and its object is to simplify the operation by a cargo worker and to prevent a collision accident to an elevator door of a transportation vehicle. SUMMARY OF THE INVENTION It is an object of the present invention to provide a luggage elevator control device capable of preventing the above-mentioned problems and performing the cargo handling work completely, and having a simple structure and a low manufacturing cost.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention is installed in a landing of each floor in a control device of an elevator for loading and unloading luggage by a transportation vehicle, and detects and detects the approach of the transportation vehicle. The detection means for generating an output, the detection means for generating a detection output, and the calling means for operating when there is no car on the corresponding floor to call the car, and the detection means It operates from the time when the detection output is generated until the car reaches the corresponding floor,
An alarm means for issuing an alarm and a door that operates while the car outputs a detection output and the car is landing on the corresponding floor to keep the elevator door open. And an open holding means.

[Action]

In the present invention, when the transportation vehicle approaches the landing of each floor, the detection means operates, and when there is no car on the floor, the call-in means is driven to call the car. At the same time, an alarm is issued until the car arrives and the alarm means is activated, and an alarm is issued to the cargo worker operating the transportation vehicle approaching the door of the elevator.

In this way, when the car called by the calling means arrives at the landing place where the transportation vehicle is approaching, the elevator door is opened and the cargo handling work becomes possible. While the vehicle is being detected, the door is held open by the door open holding means.

Further, when the transportation vehicle approaches the hall where the car is on standby, the door of the elevator is opened, and similarly, while the transportation vehicle which is present close by the detection means is detected, the door is opened. The door is held in an open state by the opening holding means.

Therefore, the collision of the transport vehicle with the elevator door is prevented, and the elevator door is kept in the open state during the cargo handling work, and the complete cargo handling work is performed.

It is assumed that the nth floor is the standby floor, and the elevator car is on standby on the nth floor, and the transportation vehicle has approached and approached the hall on the first floor.

The light beam emitted from the photoelectric device 1PH due to the approach of the transportation vehicle to the landing is blocked by the transportation vehicle, so that the photoelectric device 1PH is energized and the contact 1PH ₃ is closed.

Therefore, since a voltage is applied to the alarm device BZ ₁ and the lamp L _{1 from} the DC power supply terminals P and N, the alarm device BZ ₁ issues an alarm and the lamp L ₁ is turned on.

Therefore, the cargo worker operating the transportation vehicle listens to the alarm of the alarm BZ ₁ and confirms that the lamp L ₁ is lit, thereby carefully performing the approach operation to the elevator door of the transportation vehicle. It is possible to wait for the arrival of the car without hitting the door of the transportation vehicle and causing an accident.

Further, since the contact 1PH ₁ is closed due to the bias of the photoelectric device 1PH, the DC power supply terminal P, the contact 1PH ₁ , and the contact 1
A closed circuit is formed by F ₁ , the relay 1H, and the DC power supply terminal N, the relay 1H is energized, and the contact 1H ₁ is closed and held by itself. By the activation of the relay 1H, the elevator control circuit operates and the car is called from the nth floor to the first floor.

When the car arrives on the first floor, the movable contact point FR of the hall selector
And the fixed contact 1S come into contact with each other, the relay 1F is urged. When the relay 1F is energized to the contact 1F ₃ is opened, alarm BZ ₁ stops operating the lamp L ₁ is turned off.

Further, since the relay 1F is energized as described above, contact 1F ₂ is closed, already photovoltaics urges 1PH
Therefore, relay 1PH ₂ is closed, so relay K
Urges.

In this manner, when the relay K is to urge the contact K ₁ relay Ry is deenergized to become open, door Yotsute elevator deenergize the relay Ry is opened.

At this time, since the relay K is energized as described above, the contact K ₂ is opened and the timer T for setting the opening time of the elevator door is not activated.

Therefore, transportation vehicles cargo handling is completed away from the landing, the door of the elevator to the photoelectric device 1PH is de-energized the contacts 1PH ₂ is opened holds the opened state, cargo operator safely Cargo handling work can be performed.

Next, for example, when the transportation vehicle approaches the first-floor landing hall in a state where the elevator is on standby on the first floor with the door closed, the photoelectric device 1PH is energized in the same manner as in the case described above.

At this time, since the relay 1F is energized, the contact 1F ₂
Is closed, the relay K is energized by energizing the photoelectric device 1PH. Due to the energization of the relay K, the contact K ₁ is opened and the relay Ry is deenergized, so that the elevator door is opened.

Also at this time, the contact K ₂ is opened by the bias of the relay K, the timer T for setting the opening time of the elevator door is not started, and the cargo handling work is completed and the transportation vehicle is removed from the landing. Until you move away, the elevator doors remain open.

In either case, when the cargo handling work is completed and the transportation vehicle moves away from the landing, the photoelectric device 1PH is deenergized, so that the contact 1PH ₂ is opened and the relay K is deenergized.

When the relay K is deenergized in this way, the contact K ₂ is closed, the timer T is started, and the contact T ₁ is closed after a predetermined time, and the relay Ry is energized to close the elevator door.
