Abstract

PURPOSE:To enhance work efficiency by, in making an exclusive operation means is activated, by invalidating call regist manipulation for floors other than activated floors. CONSTITUTION:An exclusive command button 68 is used when a dumwaiter is to be used several times by registering destination calls from the present floor. In manipulating this button 68, the manipulation at other floors is invaliated thereafter until the button 68 is manipulated again. Exclusive operation indication lamps 41-44 are lighted in exclusive operation when the exclusive command button 68 is manipulated or destination call button 51-54 are manipulated for call register, so that it is displayed what floors a dumbwaiter is being used at. Accordingly, goods loaded in a cage can be carried to objective floors in accordance with the thought by a person using it preferentially, thereby enhancing the work efficiency.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric dumbwaiter for transporting cargo exclusively.
The present invention relates to a control device for a dumbwaiter using a group of operating devices configured to make it convenient to operate the dumbwaiter.

[Conventional technology]

Unlike shared elevators, dumbwaiters carry only luggage without people, and unlike shared elevators, the person inside the car does not move the car up or down by directing the car's destination. The person on the side of the hatch, who is raising and lowering the car, uses the operation panel on the side of the hatch to direct the destination of the car and raise and lower the car.

The dumbwaiter operated from the hatch side in this way is
Once the elevator starts going up and down in response to one call, it will no longer respond to calls from other floors, and will be used as a dumb waiter exclusively for the first call until the elevator arrives.

In other words, the operation of loading luggage on the first floor, then loading it from the second floor, and going to the fourth and first floors is the same as loading luggage, so a dumbwaiter that is controlled in this way is a type of boat fishing. Not in.

For this reason, the dumbwaiter control device is a means for registering only the destination floor call for one car (hereinafter referred to as the "destination call") on the operation panel on the hatch side. All you have to do is register it in , and then move the car up and down. Since only one name is required,
The above-mentioned call registration means on the operation panel provided on the hatch side is configured to "return" only the display of the destination call button for registering the destination call of the floor where the operation panel is installed (on the operation panel common to each floor).
In some cases, it is. ), and the destination call buttons built into the operation panel are connected in parallel to each floor and input to and controlled by the control device of the dumbwaiter. In other words, it does not matter which floor the destination call is registered.

Such dumbwaiter control devices have been manufactured and used without change for the past several years.

However, in recent years, from the perspective of improving the efficiency of dumbwaiter operations, there has been a demand for an easier-to-use operation method.

However, for the reason mentioned above, the control device for the dumbwaiter, which can be configured with only basic circuits, only provides a visual indicator to indicate that a car has arrived, and a sound signal using voice synthesis. .

Incidentally, as with this dumbwaiter, where the destination call is controlled on the hatch side, elevators are also used.
No. 83 (Japanese Patent Application No. 62-154372) ``Elevator Call Registration Device.'' As can be seen from the description in this publication, the technology is different from the technology of the dumbwaiter according to the present invention, since it is designed on the assumption that a large number of people can ride together.

[Problem to be solved by the invention]

In this way, dumbwaiter control devices consist only of basic circuits, and until now no efforts have been made to improve operational efficiency.However, in recent years, with the rise in logistics, dumbwaiter -However, as opportunities to transport large amounts of cargo have increased, various demands have been made.

One of these is the demand for countermeasures against the following problems.

In this way, the destination call buttons on the control panel on each floor are all connected in parallel, so any destination call can be registered from any floor, so the next user on a different floor can There is a problem in that if the destination call registration operation is performed first, the luggage of the person currently in use will be carried to a floor other than the intended one.

[Means to solve the problem]

A feature of the present invention for achieving the above object is that a signal from a destination call button for inputting a command to send a car to each floor in the operation panel of each floor is inputted to a control device for each floor, and A dedicated command button was provided in each operation panel, and the signal when this button was operated was input to the control device separately for each floor.

[Effect]

It is now possible for the control device to receive input signals from the destination call button in the operation panel of each floor and the newly installed dedicated command button for each floor, so you can control the dumbwaiter on which floor you are currently operating it. This makes it possible to register the destination call from the floor you are operating on the call registration means with priority, even if the destination call button on the operation panel of another floor is operated. However, the luggage loaded in the basket can be carried to the desired floor according to the wishes of the person using the basket with priority, without having to respond to this request.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

The dumbwaiter of the present invention is a four-story dumbwaiter from the -th floor to the fourth floor. The door on the hatch side of this dumbwaiter is a door that is opened and closed by hand, and there is no door on the car side. Note that the door on the hatch side is equipped with a door lock device to prevent it from opening unless the car is on that floor.

FIG. 1 is an explanatory diagram for explaining the operation surface of the operation panel 26, which has the same configuration on each floor according to the present invention. The indicator lights at the upper left and right ends of the figure are lit to indicate whether the dumbwaiter car is running in the upward direction or in the downward direction, and are the upper direction indicator light 71 and the lower direction indicator light, respectively. It is 72.

Surrounded by these indicator lights are car position indicator lights 31-34. The end of the number in this code indicates the destination call floor of the dumbwaiter. This car position indicator light lights up to indicate when the car reaches that floor (between the middle of the upper floor and the middle of the lower floor). In addition to this function,
Indicates that the destination call is registered based on the operation of the destination call button. In order to distinguish this display from the continuous lighting of the car position display, it is displayed by flickering lighting with a short lighting time and a long off time. However, if the car position display and the destination call display are the same, flicker lighting with a long period of one lighting time is used to indicate that both are the same. Note that this state occurs when the car operates in response to a destination call and reaches that floor.

Push button switches are lined up in the middle of the control panel. Destination call button from the left to the first floor, then to the second floor.

This is the destination call button for the third and fourth floors. Press this button to send a command to the control device to summon a dumbwaiter basket or to load luggage and take it to the destination floor.

The dedicated command button 68 on the right end is used especially when the user wants to register a destination call from the current floor and use the dumbwaiter several times. When this button is operated, subsequent operations on other floors are disabled until the button is operated again. In addition, in this embodiment, disabling the destination call operation on another floor is automatically performed by simply operating the destination call buttons 51 to 54, but unlike the above, the destination call operation on another floor is automatically disabled. Other calls are invalidated only until the door is opened after reaching . Details of these will be described later using flowcharts and the like.

The dedicated operation indicator lights 41 to 44 at the bottom of the operation panel are activated when the dedicated command button 68 is operated or when the destination call buttons 51 to 5 are activated.
When the operator registers the dumb waiter in the call registration means by operating 4, the dedicated operating indicator light for the operated floor lights up, indicating which floor the dumbwaiter is being used.

There is also an emergency stop switch (not shown) inside the operation panel 26, but its operation is the same as usual, so a description thereof will be omitted.

FIG. 2 is an overall configuration diagram showing the connection relationship between the operation panels and control devices on each floor described above. In the figure, in order to distinguish between the operation panels 26 provided on each floor, a is added to the end for the first floor, b is for the second floor, C is for the third floor, and d is added for the fourth floor. All wiring from these operation panels is connected to a microcomputer control device 81 which is a control device for the dumbwaiter.

Among these wirings, car position indicator lights 31 to 3 on each floor
4 and the dedicated running indicator lights 41 to 44 are connected in parallel from the microcomputer control device 81 as an indicator light related output line 47, and are controlled to turn on/off at the same time.

Input lines 48a to 48d related to push buttons of destination call buttons 51 to 54 and dedicated command button 68 (a =
(d represents each floor as above) are directly input to the microcomputer control device 81. therefore,
Each operating floor can be determined by the signals from the input lines related to the push buttons.

Fine-grained control can be performed by the microcomputer control device 81.

Although not shown, when the hatch side door 43 of each floor is closed, a signal from a door switch that closes the circuit is individually input to the microcomputer control device i81.

Next, the software of the microcomputer control device 81 that collectively controls each of the hardware equipment groups described above will be described with reference to FIG.

FIG. 3 is a flowchart describing the entire processing procedure of the software according to the present invention. The first terminal 4 in this diagram
51 (timer interrupt) indicates that this process is a program started by a timer interrupt. That is, this program uses a method of processing the controlled object by time division, and timer interrupts occur at a constant cycle (for example, 40 m).

This program is started by an interrupt signal to the microcomputer, sequentially executes block 453 and block 461, and finally terminates this interrupt processing at terminal 463 (return).
This returns to the main routine (not shown). Note that blocks 455, 457, 459 within block 453
is a more detailed explanation of block 453,
These are also executed sequentially when block 453 is executed.

Therefore, this timer interrupt processing is designed to finish within the above-mentioned fixed cycle at worst, and the flicker cycle is calculated by counting the number of times this program is executed (one time is 40m). ing.

The first block 453 in FIG. 3 checks whether the destination call button has been operated, determines whether it is okay to register that the button has been pressed, and sends the information to the actual operation control means in the first block 461. A process is performed to output the destination floor for raising and lowering the dumbwaiter as a destination call command.

The next block 461 is based on the destination call command output from block 453, and is the same as the timing for controlling the current position of the car (turning on/off of the car position indicator light described above).This process is also within this block. I'm doing it.

) and the destination floor specified by the destination call command, it is determined whether to ascend or descend, and the dumb waiter drive device is driven to raise or lower the car. Note that the command for elevating and lowering depends on the presence or absence of a destination call command, but for actual elevating and lowering, it is necessary that the door is completely closed.

In this way, when the elevator starts moving up and down and the destination floor coincides with the current position, the drive device is stopped by the stop limit switch, which is activated at various times, and the dumbwaiter is stopped at the fixed position. In order to go up and down again from this point, when a destination call command different from the current position is input, the same procedure as above is used to go up and down.

Furthermore, a block 455 constituting the block 453 for creating a call command performs processing for detecting a dedicated operation command, that is, processing when the dedicated command button explained in FIG. 3 is operated, and the next block 457 This is to perform a reset process after detecting a driving command. and,
The last block 459 determines whether or not the signal can be outputted as a destination call command to the next block 461 when the destination call button is operated based on the result of dedicated operation command detection, and outputs the signal. It is something.

These details will be further explained below using flowcharts shown in FIGS. 4 to 6. Note that each time the following operations or actions are performed, how they are processed will be explained in order.

(1) When the dumbwaiter is stopped on the first floor with all doors closed (2) When the door on the first floor is opened to carry luggage from the first floor to the third floor and loaded with luggage (3) 3 When you press the destination call button for a floor (4) When you close the door on the 1st floor (5) When you stop on the 3rd floor (6) When you open the door and unload your luggage (7) When you close the door on the 3rd floor When closed, the above operations were performed assuming that luggage was being transported from the first floor to the third floor. In addition, in the following explanation, for the sake of simplicity,
Regarding each processing block in each flowchart, the description of "block" is omitted, and only the reference numerals shown in the figure are written.

1 When the dumb waiter is 1 and all the a's are stopped and stopped, when the program shown in FIG.
(dedicated operation command detection) is executed. First, terminal 5 indicates the detailed flowchart of block 455.
There is 01. In the next block 503, block 607
Check whether there is a dedicated operation command floor set using the dedicated command button. Since nothing is currently set, it is checked in block 505 whether the dedicated command button has been operated. Since no operation has been performed based on the above setting conditions, it is checked in the next block 509 whether or not there is a dedicated operation command floor (created in block 607) based on the destination call. Based on the setting conditions, it is not determined at the present time, but in the next block 601 it is checked whether the destination call button has been operated. Since it is not operated as above, the next block 60
Step 5 to check if the door is open. Since it is closed from the first setting condition, this flowchart ends at the next terminal 611.

Then, terminal 7 in the next figure 5 (dedicated operation command reset)
Go to 01. Terminal 701 indicates a detailed flowchart of block 457. In the next block 703, it is checked whether the dedicated operation command flag is set, but as described above, since it is not set, this flowchart ends at terminal 723.

The next step in FIG. 6 (Destination Call Command) starts from terminal 801 indicating the detailed flowchart of block 459. In the next block 803, the operating state of the dumbwaiter is checked. Since it is still stopped, it is checked in block 805 whether a destination call command has already been output. Since no output is currently being made, it is checked in the ninth block 807 whether or not the destination call button has been operated. Since this button has not been pressed either, this flowchart ends at block 817.

Therefore, the second row ahead call command is not output to the actual operation control means in the next block 461, so the dumbwaiter remains stopped. Further, the processing contents of subsequent timer interrupts are the same until the state changes to the next step (2).

When the door is opened from the above state (1), the following processing occurs.

In Fig. 4 (dedicated operation command detection), terminals 501-503 (dedicated operation command method using the dedicated command button) -505 (dedicated command button) -509 (dedicated operation command 11i by destination call) are detected because the door is opened. -601 (destination call button) -605 (door status) -607 (dedicated operation command floor set) Processed with one terminal 611, sets the floor where the door is open as a dedicated operation command method, and also sets a dedicated operation command Also sets flags. That is, the activation of the dedicated operation command means is indicated by the set of this dedicated operation command flag. Although not shown, when this dedicated operation command technique is set, control is performed so that the indicator light corresponding to that floor among the dedicated operation indicator lights 41 to 44 lights up. Therefore, if you look at this indicator light on another floor, you will know that a dumbwaiter is being used.

In the next figure 5 (dedicated operation command reset), terminals 701-703 (dedicated operation command flag) - 705 (dedicated operation command method using the dedicated command button) - 713 (dedicated operation command method by opening the door) -714 (door open after operation) 1 terminal 7
23, it is processed.

The process in block 713 checks whether the special operation command technique is activated when the door is open (processing in block 607 in Figure 4), and if the special operation instruction technique occurs during this process and the door is open or due to other factors. When a driving command is generated, the process goes to the first block 714, but if the only special driving command technique is when the door is opened, and the door is then closed, the process goes to block 7.
In step 21, the dedicated operation command flag and the dedicated operation command techniques for all factors are reset. In other words, when the dedicated operation command technique is set with the door open, when the door is closed,
This resets the dedicated operation command technique and enables destination call registration on other floors.

The next block 714 is for detecting whether the door is opened after the dumbwaiter is operated in accordance with the destination call command and stopped. Namely.

When a dedicated operation instruction technique is set for a reason other than door opening, the operation is always performed once, and if the door is not opened, block 721 is not reset. In addition, if this dedicated driving command period is not until the door is opened, but also until the destination call button is operated, it is preferable to include the above conditions in this route. This has the effect that the destination call from that floor can be registered more reliably.

In the next FIG. 6 (destination call command), the same process as in (1) above is performed.

Further, under this condition, this processing is the same for subsequent timer interrupts.

If you press the call button on the 33rd floor with the door open, the process in Figure 4 (dedicated operation command detection) changes as follows.

Terminals 501-503 (Dedicated operation command method using the dedicated command button)-505 (Dedicated command button)-509 (
Dedicated operation command by destination call -601 (Destination call button) -603 (Dedicated operation command and dedicated operation command floor) -60
7 (dedicated operation command flag set) is processed with one terminal 611, and a dedicated operation command floor with one destination call is added to the dedicated operation command floor with the door open. At this time, the operating floor for calling the destination is:

The door must be operated on the same floor as the one on which it is opened. If the floor is different, the exclusive operation command is reset by going to the terminal 611 and calling one line ahead, and the dedicated operation command floor is not set.

The process in FIG. 5 (dedicated operation command reset) remains the same, but in the next step in FIG. 6 (destination call command), the steps starting from block 807 change because the 1st destination call button has been operated.

That is, terminals 801-803 (operating state) - 805 (
Destination call command) - 807 (Destination call button) - 809 (
(Judgment of dedicated operation command floor) - 813 (Destination call command set) - Terminal 817 and destination call command are set. However, only when the floor on which the 9th destination call button was operated as determined in block 809 matches the floor registered as the dedicated operation command floor in block 603, block 8
13, the destination call is set as the destination floor, and even if you operate the destination call button on a floor other than the registered floor (in this case, the floor where the door was opened and the destination call button was also operated), the destination call button will be set as the destination floor. I will never accept this.

In addition, dedicated operation indicator lights 41 to 44 are installed on the operation panel of each floor to indicate that a dedicated operation command floor has been registered by lighting them, so that those who have registered and who are using the dumbwaiter on another floor are prohibited. This has the effect of making it easier for those who wish to do so to know whether or not they can perform the operation.

Furthermore, when a discrepancy is detected in block 809, the process starts from block 809 and ends at terminal 817, but operating the destination call button on another floor indicates that you want to use it on another floor, so this route is It is advisable to operate the other floor requesting means when passing through. That is, as the other floor requesting means, it is also possible to provide a different floor usage request indicator light on the operation panel to request the operator to shorten the time and quickly complete the transportation. In addition to this indicator light, it would be even more effective to use voice synthesis to tell the person operating the device, ``We will use it next time, so please transport it quickly.''

Note that in the first timer interrupt, the process shown in Figure 4 sets the dedicated operation command floor for the destination call, so the terminals 501-50
3 (Dedicated operation command floor with dedicated command button) -505 (
Dedicated command button)-509 (Dedicated operation command with destination call!Replaced with terminal 611, the operation status of the dedicated command button of the upper condition is checked, but the determination of the destination call button and door opening of the lower condition is not necessary. .

In addition, the processing in FIG. 6 is carried out at terminals 801-803 (operating status) - 805 (destination call command) - 811 (judgment of current position) and terminal 813, and block 811 compares the destination call and current position, which is a reset condition. If they match, the process goes to block 815 and resets the destination call command. In addition,
When the destination call button for a floor that has been stopped from the beginning is pressed, a match is made at this point and the process is reset, so the set state in block 813 ends in one cycle of the timer interrupt.

Although not shown in the flowchart, the destination call display function of the car position indicator light in the operation panel is performed by this block 81.
Flicker lighting starts when the destination call command is set in step 3, and continues until it is reset in block 815 after reaching the destination floor and changing to a flicker cycle with a longer lighting time.

4- When you close the door I put my luggage on the dumbwaiter and closed the door.

The process is as follows and the elevator starts moving up and down.

The processes in FIG. 4 (dedicated operation command detection), FIG. 5 (dedicated operation command reset), and FIG. 6 (destination call command) are unchanged, and in the actual operation control means of block 461, when the door is closed, the dumbwaiter -Start driving. Due to this operation, the terminals 801-803 (operating state) and terminal 817 in FIG. 6 are processed, and the destination call command is maintained until it is stopped.

At 5-3, the dumbwaiter continues to operate, and when the car reaches the third floor and the stop limit switch is activated, the dumbwaiter is stopped by the process of the actual operation control means in block 461. Due to this stop, the processing changes as follows.

4 (dedicated operation command detection) and FIG. 5 (dedicated operation command reset) are the same, but the processing in FIG.
destination call command) -811 (judgment of current position) -815 (
Destination call command reset) One terminal 817 and the destination floor set as the one destination call command match the current position, so
Destination call command is reset.

Then, in the next timer interrupt, the terminal 801-8 in FIG.
03 (operating status) -805 (destination call command) -807
(Destination call button) One terminal 817 waits for the next destination call button to be operated.

6 If you are at the door and stop when you close 1), 3
The user of the dumbwaiter waiting on the floor opens the door and unloads the luggage from the basket.

By opening this door, the process begins as follows.

Figure 4 (dedicated operation command detection) does not change, but in Figure 5 (dedicated operation command reset), terminals 701-703 (dedicated operation command flag) - 705 (dedicated operation command layer with dedicated command button) - 713 (Dedicated operation command layer on the door floor) −
714 (door open after operation) - 721 (dedicated operation command reset) terminal 723, and when this door opens after operation and stop, reset the dedicated operation command flag and the dedicated operation command layer (door open) and the reset of the dedicated driving command layer upon destination call). In other words, until this door is opened, calls from other floors will not be answered. This is because the vehicle is loaded with luggage and cannot be used next unless the door is opened and the luggage is removed.

In addition, at the next timer interrupt after this reset, the process in Figure 4 is the same as that at the time of opening the door in (2) above, and the third floor is designated as the dedicated operation command layer when the door is opened. This is set, and from now on, destination call registration from this floor will be performed preferentially. That is, if the door is open, there is a possibility that luggage will be loaded into the basket, and if luggage is loaded, other users will not be able to use the dumbwaiter. In addition, in such a case, if another user would like to use it, please
You must contact the person using the intercom and ask the person on the third floor. In addition, if you want to give priority to the person who operated the destination call button first rather than contacting in this way, when you activate the other floor use request means described above, register it as the next dedicated operation command. Just leave it there.

The process in FIG. 6 (destination call command) remains unchanged as the destination call button is still waiting for operation.

7 When the door closed this time, I closed the door without putting any luggage on the dumbwaiter, so it worked as follows. In Figure 4, terminal 5
01-503 (Dedicated operation command layer with dedicated command button)
-505 (Dedicated command button) -509 (Dedicated operation command layer for destination call) -601 (Destination call button) -605
(Door state) One terminal 611 and the route to the dedicated operation command flag set state are eliminated.

In the following figure 5, terminals 701-703 (dedicated operation command flag) - 705 (dedicated operation command layer with dedicated command button) - 713 (dedicated operation command layer when door is opened) - 721 (dedicated operation command flag reset) ) terminal 723, the dedicated operation command layer and the dedicated operation command flag are reset when the door is closed and the dedicated operation command layer and the dedicated operation command flag are reset when the door is opened.In addition, in Fig. 6, the state is unchanged from the previous state, waiting for operation of the destination call button, and the initial state ( Return to state 1).

Next, as another operation, a case in which the dedicated command button 68 in the operation panel 26 is operated will be described.

In Fig. 4 (dedicated operation command detection), the dedicated command button 68
When is operated, terminals 501-503 (dedicated operation command # with dedicated command button)-505 (dedicated command button)-6
03 (Dedicated Operation Command and Dedicated Operation Command Layer)-607 (Dedicated Operation Command Floor Set) A dedicated operation command layer and a dedicated operation command flag are set by one terminal 611 and the dedicated command button. However, this set is only available when the dedicated operation command flag is not set by the time the dedicated command button is operated.
Or, even if it is set, it is the same operation floor as the dedicated operation command floor. Not set if different. Also, as can be seen from this flowchart, setting using this dedicated command button is given top priority.

After setting, the terminals 5o1-503 (dedicated operation command floor using the dedicated command button)-terminal 611 in FIG. 4 are processed, and the processing of lower conditions is ignored.

In the following figure 5 (dedicated operation command reset), when the dedicated operation command flag is set, terminals 701-703 (dedicated operation command flag) -705 (dedicated operation command floor with the dedicated command button) -709 (dedicated operation command floor) Command button) - 715 (Door closed after opening operation door) - Processed with terminal 723, the dedicated command button is pressed again or the dumb waiter is operated,
Three minutes have passed since the door opened and then closed.

At block 721, the dedicated run command floor and dedicated run command flag are reset.

This 3-minute timer is for automatically resetting when you forget to operate the dedicated command button for the second time, which is the operation to cancel the dedicated operation command floor using the dedicated command button. be. That is, in this embodiment, no particular release button is provided as a means for resetting the dedicated operation command floor, and the reset is performed by pressing the dedicated command button twice. Note that the block 715 is set after the vehicle stops at the destination floor, opens the door, unloads the luggage, and closes the door, that is, becomes unused.

Block 717 operates a three-minute timer.

If the dedicated command button is operated for the second time before this, the process will be as follows.

Terminals 701-703 in Figure 5 (dedicated operation command flag)
-705 (Dedicated operation command floor with dedicated command button) -70
9 (dedicated command button) - 721 (dedicated operation command reset) - Processed with one terminal 723 to reset the dedicated operation command floor and the dedicated operation command flag. Therefore, if the door was open before resetting this dedicated operation command floor,
When the door is opened, the dedicated operation command layer is set again, and when the destination call button is operated, the destination call command has already been set in the destination call command process in Figure 6, so when the door is closed, the dumb waiter is be driven.

Although not shown in the flowchart, since the dedicated command button is reset by pressing it twice, the dedicated operation command floor in block 607 is set so that the set/reset is not repeated even if the button is held down. After setting, operate the dedicated command button □ Disable the signal capture and enable it after 1 minute. Therefore, if you keep pressing the button for more than 1 minute, reset it immediately.

As an effect of this dedicated command button, it can be used as follows, for example, when carrying luggage repeatedly from the - floor to the third floor. First, operate the dedicated command button to set the dedicated operation command floor. Then, press the destination call button on the third floor to determine your destination floor. When I loaded my luggage and went to the third floor,
-Press the destination call button on the first floor from the floor and command the person to come back. If you do this and close the door after unloading your luggage on the third floor, you will return to the first floor. If the same procedure is repeated thereafter, the person operating the third floor only needs to unload the luggage, and the effect is that all operations can be performed only on the - floor.

In addition, a case will be described in which a dumbwaiter, which is stopped on the third floor with the door closed, is called to the -floor. At this time, when the destination call button 51 is pressed on the operation panel 26a of the - floor, the dedicated operation command floor with the destination call button is set to the first floor as described above.

Therefore, the exclusive operation indicator light 41 lights up, indicating that the vehicle is being used on the - floor. The first floor is set in the destination call command, and the dumbwaiter descends toward the - floor and arrives at the first floor. If the dedicated operation command floor has arrived, the dedicated operation command floor will not go to the reset block 721 at block 714 (door open after operation) in FIG. 5 (dedicated operation command reset), so it will remain as it is. Therefore, in the conventional example,
During this time, if you called for a car on another floor, the car would respond, but in this embodiment, even if you called as described above, the car would not respond.

effective.

Then, when the door is opened, the blocks 714 to 72
1 and the dedicated driving command layer is reset. However, at the next timer interrupt, in block 605 (door shape 1 m) in FIG. 4 (dedicated operation command detection), the - floor is again set as the exclusive operation command layer.

In this state, if you load your luggage and close the door, the dedicated operation command layer will be reset, allowing calls to be made from other floors. At this time, if the operator happens to operate it on another floor, the baggage loaded on the - floor will not go to the destination floor, and the operator will not be able to load the baggage.

A dedicated command button 68 is provided as an operation to prevent such a situation. No matter when this button is operated,
If the operated floor is in the dedicated operation command layer, the dedicated operation command layer using the dedicated command button is set preferentially.
