Description

  The present invention is provided at each of the plurality of stop positions, a small baggage transporting basket that can be moved up and down along a lifting path in which a plurality of stop positions are set, a lift drive means for driving the basket up and down, and A plurality of manually operated operation setting means for instructing a target stop position for raising and lowering the basket from the plurality of stop positions, and a commanded target stop position based on command information of the plurality of operation setting means And an operation control means for controlling the operation of the raising / lowering driving means to raise and lower the basket.

  Such an elevator for small parcels is used in such a manner that small parcels are stored in the basket without an operator boarding the cart. For example, a dish cooked in a kitchen at a restaurant or hospital is used. As a small parcel, the basket will be stopped, such as being transported to a serving place on another floor, or used to transport containers after eating and drinking at the serving place as a parcel to the kitchen. It is used to transport various small packages from one stop position to another stop position.

And in order to convey a parcel with such an elevator for small parcels, that is, to raise and lower the basket from one stop position to the other stop position among a plurality of stop positions where the basket is to be stopped. The target stop position for raising and lowering the car is set by the operation setting means provided at each of the plurality of stop positions at which the car is to be stopped.
In other words, first, the operation setting means installed at the stop position from which the parcel is transported instructs the stop position at which the operation setting means is installed as the target stop position, and stops the car from the transport source. Will be raised and lowered to the position. Incidentally, it is needless to say that raising and lowering of the basket according to this command is not necessary if the basket is stopped at the stop position that is the transfer source when the small package is to be transferred.

  When the basket arrives at the stop position serving as the transport source, the transported parcel is stored in the arrived basket. After that, the operation setting means installed at the stop position as the transport source instructs the stop position as the transport destination of the small package as the target stop position, thereby stopping the basket storing the small package as the transport destination. Will be raised and lowered.

By the way, in general, at each of the plurality of stop positions in the basket lifting path, a loading / unloading opening for loading and unloading a small package that connects the lifting path of the basket and the outside is formed, and a loading / unloading door that opens and closes the loading / unloading opening is provided. In addition, the basket will be equipped with a cage door that opens and closes an opening for putting in and out of small packages.
The entrance door and the basket door are operated in an open state during storage work for storing small packages in the basket and for taking out small packages from the basket. In the standby state, the user is operated in the closed state.

Many doors and doors are opened and closed manually by the user. In this case, the doors are automatically opened and closed when the doors are opened and closed. In many cases, a linkage mechanism that links the entrance door and the basket door is provided.
Further, there is a case in which driving means for opening and closing the entrance door and the basket door is provided, and the driving means is operated according to a user opening / closing command to open and close the entrance door and the basket door. In this case, when the basket is raised and lowered to the stop position that is the transfer source, the doorway and the basket door are opened, or the basket that stores the small parcel is raised and lowered to the stop position that is the transfer destination. Then, there is a case where the driving means is automatically operated to open and close the entrance door and the basket door.

By the way, when transporting a small package using a dedicated elevator for small packages, the package may be transported in a state where one of a plurality of stopping positions where the basket is stopped is used as a transport source, The transport source may change over time.
For example, in a restaurant, the food cooked in the kitchen is transported to a kitchen as a small parcel, and the containers after eating and drinking at the serving area are transported to the kitchen as a small parcel. However, since food and beverage customers come to the store during lunch and dinner, during the time when the food and beverages come to the store, dishes prepared in the kitchen are used as small parcels and served on different floors. In this time zone, the state where the stop position corresponding to the kitchen is used as the transfer source is continued. In addition, in the time zone after the customers who have finished eating and drinking return, the containers after eating and drinking at the catering location are transported to the kitchen as small packages, and such time zone In this case, the state where the stop position corresponding to the arrangement location is the conveyance source is continued.

  In this way, when a small parcel is transported in a state where one of a plurality of stop positions where the basket is to be stopped is used as the transport source, the stop position that is the transport source of the small parcel is set. The installed operation setting means commands the stop position where the operation setting means is installed as a target stop position, and raises and lowers the cage to the stop position that is the transfer source, and is installed at the stop position that is the transfer source. By the operation setting means that has been performed, the stop position that becomes the transport destination of the parcel is commanded as the target stop position, and the basket that stores the parcel is raised and lowered to the stop position that becomes the transport destination, There is a disadvantage that the operation of the operation setting means becomes complicated.

  In other words, the operator located at the stop position of the transfer source instructs the stop position of the transfer source as the target stop position, raises and lowers the basket to the stop position as the transfer source, and is positioned at the stop position of the transfer source. When the operation of storing the parcel in the basket is completed, the stop position that is the transport destination of the parcel is commanded as the target stop position, and the basket that stores the parcel is moved up and down to the stop position that is the transport destination. After that, after confirming that the parcel has been taken out at the transport destination of the parcel, after confirming that, the stop position of the transport source is instructed as the target stop position, and the basket is transported. Since raising and lowering to the original stop position is repeatedly performed, the operation of the operation setting means by the operator located at the stop position of the conveyance source becomes complicated.

Therefore, conventionally, it has been proposed to automatically return the cage that has been raised and lowered to the stop position of the transport destination to the stop position of the transport source.
That is, for each of a plurality of stop positions, the use frequency for each time zone is counted, and learning is performed to set the reference stop position for each time zone from the counted use frequency, and the reference stop position is different from the reference stop position. It has been proposed to configure the car that has been raised and lowered to the stop position to automatically return to the reference stop position and to be raised and lowered (see, for example, Patent Document 1).
Incidentally, in the above-mentioned Patent Document 1, there is no detailed description about counting the usage frequency for each time zone and setting the reference stop position for each time zone from the counted usage frequency. The frequency of use is counted, and the reference position is set by learning the past use frequency prior to the current day, such as setting the reference position for each time period of the current day based on the frequency of use for each time period of the previous day. It is thought to be.

Japanese Patent Laying-Open No. 2005-1770 (page 7)

  Conventionally, in determining the base stop position for automatically returning the basket, the base stop position is determined by counting the past use frequency before the current day. If the usage condition of the car is different, there is a possibility that the car cannot be raised and lowered appropriately.

In other words, in restaurants, for example, the time zone for eating and drinking customers tends to be different on weekdays and holidays, but if the time zone for eating and drinking customers is different on weekdays and holidays, The time period when the cooked dishes are transported to a serving place on another floor as small parcels, and the containers after eating and drinking at the serving place are transported to the kitchen as small parcels. The concentrated time zone will vary between weekdays and holidays.
For this reason, if the previous day is a weekday and today is a holiday, the reference stop position may be set in a kitchen or serving place at a time different from the preferred time on that holiday.

  As described above, in determining the reference stop position for automatically returning the car, if the reference stop position is determined by learning the past use frequency before the current day, the reference stop position may not be set to a preferable state on the current day. Therefore, improvement was desired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a small baggage lifting / lowering machine capable of satisfactorily transporting small packages by setting a reference stop position in a preferable state for the day. The point is to provide.

The elevator for small parcels according to the present invention includes a cart for transporting small parcels that can be lifted and lowered along a lifting path in which a plurality of stop positions are set,
Elevating drive means for elevating and driving the basket;
A plurality of manually-operated operation setting means provided at each of the plurality of stop positions and commanding a target stop position for raising and lowering the basket from the plurality of stop positions;
Operation control means for controlling the operation of the elevating drive means to raise and lower the car to the commanded target stop position based on the command information of the plurality of operation setting means, One feature configuration is
The operation control means is
Current generation of a basket feed command in which a target stop position is commanded by each of the plurality of operation setting means to raise and lower the cage located at the stop position where the operation setting means is installed to a different stop position The frequency is selected for each of the plurality of operation setting means according to a setting selection condition that preferentially selects the one close to the current time among the generation times of the basket feed command existing retroactively from the current time A reference stop position learning process for determining a stop position where the operation setting means having a high occurrence frequency among the plurality of operation setting means is set as a reference stop position, obtained based on the generation time point of the car feed command to be performed; ,
In a stop state outside the reference stop position where the basket is stopped at a stop position different from the reference stop position, a standby state where a setting standby condition in which command information is not commanded by the plurality of operation setting means is satisfied is a set standby time It is characterized in that an automatic return process for raising and lowering the basket to the reference stop position is executed after a lapse of time.

That is, the operation control means executes a reference stop position learning process for setting the reference stop position and an automatic return process for raising and lowering the basket to the set reference stop position.
In the reference stop position learning process, there are a plurality of current occurrence frequencies for the car feed command in which a target stop position is commanded to raise and lower the car located at the stop position where the operation setting means is installed to a different stop position. Each of the operation setting means is required separately.
In other words, when the worker located at the transport source stop position finishes the operation of storing the parcel in the basket located at the transport source stop position, the stop position that becomes the transport destination of the parcel is set as the target stop position. When the command is issued, the command is used as a cage feed command, and the current frequency of occurrence of the cart feed command is obtained for each of the plurality of operation setting means.

More specifically, the current occurrence frequency of the basket feed command is selected based on a setting selection condition that preferentially selects a cart feed command that exists retroactively from the current time. It is obtained based on the time when the basket feed command is generated.
In this way, among the cart feed commands existing retroactively from the present time, the one close to the current time is preferentially selected, and the current cart feed command is selected based on the generation time of the selected cart feed command. Since the occurrence frequency is obtained, the obtained occurrence frequency represents the occurrence state of the current basket feed command.
Then, the stop position where the operation setting means having the current occurrence frequency for the basket feed command obtained from the plurality of operation setting means is set as the reference stop position.

In the automatic return processing, in a stop state outside the reference stop position where the basket is stopped at a stop position different from the reference stop position, there is a standby state that satisfies a setting standby condition in which command information is not commanded by a plurality of operation setting means. When the set waiting time elapses, the basket is moved up and down to the reference stop position.
In other words, in the stop state outside the reference stop position where the basket is stopped at a stop position different from the reference stop position, the standby state where the set standby condition in which the target stop position is not commanded from any of the plurality of operation setting means is satisfied. If the set time continues, the car is moved up and down to the reference stop position.

As described above, when the stop position where the operation setting means that frequently instructs the basket feed command is installed is set as the reference stop position at this time, and the basket is stopped at a stop position different from the reference stop position. In addition, even if the set standby time has elapsed, if the command for raising and lowering the car is not instructed by a plurality of operation setting means, the car is automatically raised and lowered to the reference stop position. Since the reference stop position can be set and the basket can be moved up and down to the set reference stop position, the reference stop position can be set in a preferable state for the day and the parcel can be transported well. It becomes.
In other words, for example, in a restaurant, the food cooked in the kitchen as a small parcel, and a time zone in which it is concentrated to transport the dish to a serving location on another floor, and containers after eating and drinking at the serving location are small parcels. As a result, even if the time zone in which the transportation to the kitchen is concentrated changes from day to day, the reference stop position can be set in a preferable state for the day and the parcel can be transported well. It becomes.

By the way, when setting the reference stop position by evaluating the raising / lowering situation of the cage, the operator located at the stop position of the transfer source moves the cage located at a stop position different from the stop position of the transfer source to the transfer source. It is conceivable that the current occurrence frequency of the command to be executed is obtained and the stop position with the highest occurrence frequency is set as the reference stop position.
However, if the parcel is not transported immediately to the transport destination even if the car is moved up and down to the transport source, the car may be lifted and lowered by the operation setting means at another stop position. The frequency at which the parcel is transported is different from the frequency at which the parcel is transported to the transport destination. For this reason, when setting the reference stop position based on the current occurrence frequency of raising and lowering the basket to the transport source, the reference stop position is appropriately set to the stop position where the current occurrence frequency for transporting the parcel to the transport destination is high. It will be difficult to set.

  On the other hand, the first characteristic configuration of the present invention is that the operator at the stop position of the transport source has the current car feed command that instructs the stop position as the transport destination of the parcel as the target stop position. Since the occurrence frequency is obtained and the stop position with the highest occurrence frequency is set as the reference stop position, the reference stop position is appropriately set to the stop position with the current occurrence frequency for transferring the parcel to the destination. It can be done.

  In short, according to the first characteristic configuration of the present invention, it is possible to provide an elevator for exclusive use of small parcels that can carry out small parcels by setting the reference stop position in a preferable state for the day.

The second feature configuration of the present invention is in addition to the first feature configuration described above.
The setting selection condition is defined as a condition for selecting a generation time point of the set number of the basket feed commands,
In the reference stop position learning process, the operation control means is configured to obtain an average of time intervals between adjacent ones at the time of occurrence of the set number of basket feed commands arranged in time series as the occurrence frequency. It is characterized by that.

In other words, since the setting selection condition is defined as a condition for selecting the generation time point of the set number of basket feed commands, priority is given to the one near the current time point among the occurrence points of the basket feed command that exists retroactively from the current time point. The point of occurrence of the set number is selected.
Then, the current occurrence frequency of the basket feed command is obtained as an average of time intervals between adjacent ones at the time of occurrence of a set number of basket feed commands arranged in time series.

  As described above, the current occurrence frequency of the basket feed command is based on the occurrence time of the set number selected with priority given to the one near the current time among the occurrence times of the cage feed command existing from the present time. Since it is obtained as an average of the time intervals between the adjacent ones, the required occurrence frequency is obtained more frequently as the time interval of the basket feed command repeatedly commanded is shorter in the time zone close to the present time. Therefore, the reference stop position can be set according to the usage situation at the time point as close as possible to the present time.

  In short, according to the second characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration described above, it is possible to provide a lift for small parcels capable of setting the reference stop position according to the usage situation at the time point as close as possible to the present time. .

The third feature configuration of the present invention is in addition to the second feature configuration described above.
In the reference stop position learning process, when the operation control means is in a state where the basket feed command is not commanded for a set allowable time, a cart feed command is generated after the set time has elapsed since the previous basket feed command was generated. As described above, the average is obtained as the occurrence frequency.

That is, in the reference stop position learning process, if a state in which the car feed command is not commanded continues for the set allowable time, it is assumed that the car feed command has been generated after the set time has elapsed since the previous car feed command was generated, and If the basket feed command is generated after the set occurrence time since the previous basket feed command is generated, the average as the occurrence frequency is obtained.
In other words, even if the basket feed command has not occurred for a long time since the last time the basket feed command was generated, if the set allowable time has elapsed, the average as the frequency of occurrence is assumed as if the basket feed command has occurred. As a result, when the car feed command is actually frequently performed, the stop position where the car feed command is frequently performed can be set to the reference stop position as quickly as possible.

That is, for example, in a restaurant, there may be a stop position where a basket feed command is not generated for a long time, for example, between a time zone for lunch and a time zone for dinner.
In addition to the explanation, the restaurant serves as a transport source when transporting containers after eating and drinking to the kitchen as small parcels after the customer who visited the store for lunch came back, and then visited the restaurant for dinner. After returning, it becomes a transport source when containers after eating and drinking are transported to the kitchen as small parcels, and it is considered that several hours pass between them.

  And, when the basket feed command does not occur for a long time, if the long time is set as a time interval between adjacent ones at the time of the occurrence of the basket feed command, then, as a transport source for transporting a small package, Even when commanding the basket feed command is started, if there is a long time interval between adjacent ones at the time when the cart feed command is generated, the average obtained as the occurrence frequency is unlikely to change to a small value. Therefore, there is a possibility that it may be delayed to set the stop position that should be the reference stop position to the reference stop position.

  In short, according to the third feature configuration of the present invention, in addition to the operational effects of the second feature configuration, the basket feed command is frequently generated at a stop position where the basket feed command may not be generated for a long time. Sometimes it is possible to provide an elevator for small parcels that can be quickly set to the reference stop position.

In addition to any of the first to third feature configurations described above, the fourth feature configuration of the present invention includes:
Each of the plurality of stop positions is provided with a loading / unloading port for a small package with respect to the basket, and a loading / unloading door for opening / closing the loading / unloading port.
The stop state outside the reference stop position is a state in which the door is closed and the basket is stopped at a stop position different from the reference stop position,
The setting standby condition is characterized in that command information is not commanded by the plurality of setting means and the opening / closing door is not opened.

  In other words, when a doorway for opening and closing the baggage door is provided, when the doorway is opened, when the baggage is being stored or taken out, that is, used You can think of it as being inside.

  Therefore, the reference stop position can be appropriately set by setting the stop state outside the reference stop position to a state in which the door is closed and the basket is stopped at a stop position different from the reference stop position. In addition, by setting the setting standby condition as a condition in which the command information is not commanded by a plurality of setting means and the doorway is not opened, the cage is appropriately raised and lowered to the reference stop position. Can be made.

  In short, according to the fourth feature configuration of the present invention, in addition to the operational effects of any of the first to third feature configurations, when a doorway is provided, the reference stop position is appropriately set, And the elevator for exclusive use of a small baggage which can perform raising / lowering a cage to a standard stop position appropriately can be provided.

In addition to any of the first to fourth feature configurations described above, the fifth feature configuration of the present invention includes:
Each of the plurality of stop positions is provided with manually operated reference position setting means for designating the stop position as the reference stop position,
The operation control unit switches the reference stop position in the automatic return process between a learning setting state set by the reference stop position learning process and a forced setting state set by setting information of the reference position setting unit. It is characterized by being freely configured.

That is, when the operation control means is switched to the learning setting state, the automatic return process is performed with the reference stop position in the automatic return process as the reference stop position set in the reference stop position learning process.
In other words, if the parcel is transported in a state where one of the plurality of stop positions where the basket is stopped is used as the transport source, the reference stop position is determined by the reference stop position learning process accordingly. It is set and the automatic return process is performed.

In addition, when the operation control means is switched to the forced setting state, the automatic return process is performed with the reference stop position in the automatic return process set as the reference stop position set in the setting information of the manually operated reference position setting means. become.
In other words, each of the plurality of stop positions is provided with manually operated reference position setting means for designating the stop position as the reference stop position, so that one of the plurality of stop positions at which the basket is stopped is selected. If you want to continue transporting small parcels in the state that is the transport source, if you specify the stop position as the reference stop position with the reference position setting means provided at the stop position corresponding to the transport source, The stop position is set as the reference stop position, and automatic return processing is performed.

  Whether the operation control means is switched to the learning setting state or the forced setting state can be arbitrarily selected by the user, but if the operation control means is switched to the learning setting state, the current operation is not required without any special operation. The reference stop position can be automatically set according to the use situation, and the reference stop position can be set according to the intention of the user by switching to the forced setting state.

  In short, according to the fifth feature configuration of the present invention, in addition to the operational effects of the first to fourth feature configurations, a mode in which the reference stop position is automatically set according to the current use situation, and the user's It is possible to provide an elevator for small parcels that can be used satisfactorily by selecting a mode in which a reference stop position is set according to the intention.

  The stop indicator light 16 is turned on when the entrance / exit door 11 on each floor is forgotten to be closed, and indicates that the car K cannot be raised or lowered.

  The emergency stop button 17 instructs an emergency stop command to immediately stop the basket K that is being lifted and lowered. Further, when the emergency stop button 17 is continuously pressed on any floor, the stop indicator light 16 of the operation panel S on each floor is lit.

  The cage position indicator lamp 18 lights the display lamp corresponding to the floor where the basket K is stopped to indicate to which floor the cage K is stopped. Further, when the car K is moving up and down, the display lamp corresponding to the target floor on which the car K moves up and down blinks to indicate that the car K is moving up and down.

  The driving direction indicator lamp 19 is composed of a pair of substantially triangular display lamps indicating the vertical direction. When the cage K is operating upward, the indicator lamp indicating the upward direction is operated, and the cage K is operating downward. In some cases, the up and down direction of the basket K during the lifting operation is shown to the workers on each floor by turning on a display lamp indicating the downward direction. Note that when the basket K is stopped on any floor and is not moving up and down, these display lamps are not lit.

Three operation buttons 20 are provided corresponding to the first to third floors, and are used to select and instruct a floor (target stop position) on which the car K is moved up and down.
In other words, when the basket K stopped on the floor that is not the floor (hereinafter referred to as the transport source) where the parcel is sent out is moved up and down to the transport source (when calling), or the basket K stopped at the transport source is small. In the case of raising / lowering (sending out) a floor to which a package is sent (hereinafter abbreviated as a transport destination), it is used to select and instruct the floor to be raised / lowered.
In addition, when the basket K is not stopped at the transport source, in order to call the cart K to the transport source, the driving operation button 20 on the operation panel S of the transport source corresponds to the transport source. When the driving operation button 20 to be pressed is operated, the control panel H raises and lowers the basket K to the conveyance source based on the command and stops the operation.

Further, when the basket K is stopped at the transport source, when the driving operation button 20 corresponding to the transport destination to which the package is to be sent is pressed among the operation buttons 20 on the operation panel S of the transport source, Based on the command, the control panel H raises and lowers the basket K to the conveyance destination and stops it.
Incidentally, when the basket K is stopped at the transport source in this way, the drive operation button 20 corresponding to the transport destination to which the package is to be sent is pushed among the drive operation buttons 20 on the operation panel S of the transport source. Operating and instructing the target stop position corresponds to a basket feed command described later.

  The voice announcement speaker 21 outputs the synthesized voice to notify the arrival of the basket K at the transport destination. That is, when the basket transported from the transport source to the transport destination arrives at the transport destination, the arrival is notified by synthetic voice.

  The reciprocal interphone 22 is an interphone that can perform voice communication with a worker on another floor selected and designated in the manner of a transceiver that is half-duplex communication. For example, when transporting a small parcel from a transport source to a transport destination, The transfer source worker is used in advance to inform the transfer destination worker that the transfer is to be performed.

  The operation panel control unit 23 is provided inside the operation panel S. As shown in FIG. 5, the operation panel control unit 23 includes the above-described entrance / exit limit switch W, the stop indicator lamp 16, and the emergency stop button 17. Input / output devices such as a basket position indicator lamp 18, a driving direction indicator lamp 19, a driving operation button 20, a voice announcement speaker 21, a mutual interphone 22, and a reference stop position setting button F are connected.

The reference stop position setting button F is used for designating a floor (hereinafter, abbreviated as a reference stop position) for automatically returning the basket K in an automatic return process to be described later. Based on (setting information), the control panel H sets the reference stop position.
That is, when the first floor is set as the reference stop position, the first floor reference stop position setting button F1 is operated. Similarly, when the second floor or the third floor is set as the reference stop position, the second floor is set as the reference stop position. The reference stop position setting button F2 and the reference stop position setting button F3 on the third floor are operated, and the floor in which the reference stop position setting button F is operated at the end of each floor becomes the reference stop position.
The reference stop position setting button F is configured to be an illumination type having a built-in lighting device, and is configured to be lit when a reference stop position is set.

  As shown in FIG. 5, the operation panel control unit 23 on each floor is connected to the control panel H via a communication cable, and the operation button 20 is communicated between the operation panel control unit 23 and the control panel H on each floor. Various input information such as an up / down command and an entrance / exit limit switch W is input to the control panel H, and as described above, the detection information of the position detection switch 7 provided for each floor, and the cage door switch 6 Detection information is also input to the control panel H.

  Based on the input information, the control panel H operates the hoisting machine M to raise and lower the basket K, and outputs the synthesized voice information to be notified by the voice announcement speaker 21. To display the current position information of the car K, etc., to the car position indicator lamp 18, to output the up / down direction information to the driving direction indicator lamp 19 during the raising / lowering of the car K, and to be lit When the condition is satisfied, an output control process for outputting the lighting information to the stop indicator lamp 16 is executed. In addition, an automatic return process for automatically returning the basket K to the reference stop position and an automatic return process thereof are performed. Therefore, the reference stop position learning process is executed.

By the way, the operation panel control unit 23 is provided with a storage device (not shown), and the storage device has “the basket has arrived”, “the door is open”, “the door at the transport destination” A plurality of audio data such as “I have been opened” and “The basket has returned” are stored.
Then, when an announcement command is commanded from the control panel H, the operation panel control unit 23 that has received the command reports among the plurality of audio data based on the identification information added to the command information. The voice data corresponding to the voice message to be extracted is extracted, and the voice announcement speaker 21 is operated based on the voice data.

The control panel H is connected to an operation unit N for inputting various information and setting a control operation.
Then, the control panel H is set to a learning setting state in which a reference stop position in the automatic return process is set in a reference stop position learning process, which will be described later, and a forced setting state in which a reference stop position setting button F is set. It is configured to be switched by N commands.

Next, the control operation of the control panel H will be described.
As described above, the control panel H performs the elevation control process, the output control process, the reference stop position learning process, and the automatic return process.
The control panel H is equipped with a microcomputer, and the control panel H includes a program for raising and lowering control processing configured in a program format, a program for output control processing, a program for reference stop position learning processing, and Various processes are executed based on the program for automatic return processing.

  In the state where the car K is stopped and the entrance door 11 and the car door 5 are closed, the lift control process is performed by setting the target stop position (floor to be lifted) by the operation button 20 of the operation panel S on any floor. When commanded, in order to raise and lower the cage K to the stop position set corresponding to the entrance / exit D of the floor commanded as the target stop position, the winding is performed based on the detection information of the stop position detection position detection switch 7. A process for controlling the operation of the upper machine M is executed.

Incidentally, even when the plurality of operation panels S are sequentially operated in a state where the basket K is stopped and the entrance door 11 and the cage door 5 are closed, the operation button 20 of the operation panel S operated first is used. The commanded floor is commanded as the target stop position.
Further, even when the car K is moved up and down to the reference stop position in the automatic return process, the floor that is instructed by the operation button 20 of the operation panel S that is operated first is then instructed as the target stop position. become.
When the car K is not stopped or when the door 11 and the car door 5 are not closed, the target stop position (floor to be moved up and down) by the operation button 20 on the operation panel S on any floor. Even if a command is issued, the command is not accepted.

  That is, for example, when the basket K stops at the first floor entrance / exit D1 and the entrance / exit door 11 and the cage door 5 are closed, an operator on the first floor operates the operation button 20 on the first floor operation panel S1. When the operation button 20 displayed on the third floor is pressed and operated (when a basket feed command is commanded), the basket K rises and is stopped at the third floor entrance / exit D3 commanded as the target stop position. become.

  In addition, when the basket K stops at the third floor entrance / exit D3 and the entrance / exit door 11 and the cage door 5 are closed, the operator on the first floor can select one of the operation buttons 20 on the first floor operation panel S1. When the operation button 20 displayed on the first floor (own floor) is pressed and operated, the car K is lowered and stopped at the first floor entrance / exit D1 that is commanded as the target stop position.

  Similarly, workers on the second and third floors can raise and lower the basket K by instructing the target stop position on the operation panel S on the floor where they are located. In this way, the worker on each floor can send the basket K stopped on its own floor to the other floor, or call the basket K stopped on the other floor to its own floor. .

  The output control process is a process of outputting the synthesized voice information to be notified to the speaker 21 for voice announcement, a process of outputting the current position information of the basket K to be displayed to the car position indicator lamp 18, and raising and lowering the car K during the raising and lowering of the car K. The process of outputting the direction information to the driving direction indicator lamp 19 and the process of outputting the lighting information, the blinking information, etc. to the stop indicator lamp 16 are executed, and the control content is clear from the above description. The description is omitted here.

  The reference stop position learning process is for each of the operation panels S installed on each floor to raise and lower the cage K located on the floor (stop position) where the operation panel S is installed to a different floor (stop position). The current occurrence frequency of the basket feed command for which the target stop position is commanded is close to the current time among the generation times of the basket feed commands existing separately for each of the operation panels S on each floor and from the current time. The floor (stop position) where the operation panel S having a high occurrence frequency among the plurality of operation panels S is obtained based on the generation time point of the basket feed command selected by the setting selection condition for preferential selection. ) As a reference stop position.

The setting selection condition is determined as a condition for selecting the generation time point of the set number of basket feed commands, and the control panel H has a set number of time-series settings as the occurrence frequency in the reference stop position learning process. An average of time intervals between adjacent ones at the time when the basket feed command is generated is obtained.
Incidentally, in the present embodiment, 6 is set as the set number, and the average of the time intervals between adjacent ones at the time when the six basket feed commands are generated is obtained.

In addition, if the control board H is in the reference stop position learning process and the state in which the car feed command is not commanded continues for the set allowable time, the car feed command is generated after the set time has elapsed since the previous car feed command was generated. The average as the occurrence frequency is obtained.
Incidentally, in this embodiment, the setting allowable time is set to 1 hour, and the setting occurrence time is set to 1 hour, but these times can be changed variously.
Therefore, if the state in which the basket feed command is not commanded continues for one hour, the control panel H obtains the average as the frequency of occurrence, assuming that the basket feed command has been generated one hour after the previous basket feed command is generated. become.

In the automatic return process, command information for commanding the target stop position is not commanded by the plurality of operation panels S in the stop state outside the reference stop position where the basket K is stopped at a floor (stop position) different from the reference stop position. When the set standby time elapses when the set standby condition is satisfied, a process of raising and lowering the basket K to the reference stop position is executed.
The set standby time can be changed and set by the operation unit N in the range of 1 to 10 minutes.

Moreover, in this embodiment, since the door 5 is opened and closed as the door 11 is opened and closed, the stop state outside the reference stop position is closed when the door 11 is closed. It is determined that the basket is stopped at a floor (stop position) different from the reference stop position.
Further, the set standby condition is set to a condition in which the command information on the target stop position is not commanded on the plurality of operation panels S and the opening / closing door 11 is not opened.

  Further, as described above, the control panel H has a learning setting state in which the reference stop position in the automatic return process is set in the reference stop position learning process, and a forced setting state in which the setting information of the reference stop position setting button F is set. In addition, since it is configured to be switchable by a command from the operation unit N, the operation unit N switches between a learning setting mode in which the learning setting state is set and a forced setting mode in which the forced setting state is set before the operation. Will be.

Hereinafter, the control operation of the control panel H will be described.
As shown in FIG. 6, first, information for reading various information such as command information of the operation unit N, information from the operation panel S of each floor, detection information of the cage door switch 6, and detection information of the position detection switch 7. Read processing is performed (# 1).

  Next, based on the information input in the information reading process, the lift control process (# 2), the output control process (# 3), the reference stop position learning process (# 4), and the automatic return process (# 5) Will be performed sequentially.

  Since the control contents of the elevation control process and the output control process are clear in the above description, the reference stop position learning process and the automatic return process will be described next.

As shown in FIG. 7, in the reference stop position learning process, first, a process of adding a count value n (denoted as the nth floor in the drawing) for determining the first floor, the second floor, and the third floor is performed (# 11). ).
The process of adding the count value n (# 11) is repeated until “3” is determined in step # 17, and when “3” is determined in step # 17, The count value n is set to “0” (# 18).

  After the process of step # 11, it is determined whether or not there is a basket feed command on the operation panel S of the floor of count n (# 12). The basket feed command is a command for a target stop position for moving the cage K located on the floor (stop position) on which the operation panel S is installed to a different floor (stop position) as described above. That is.

If it is determined in step # 12 that a basket feed command has been issued, a process is performed in which the elapsed time from the previous occurrence of the basket feed command and execution of the average calculation process is determined as the elapsed time for calculation (# 13). Next, an average calculation process for obtaining the average elapsed time of the floor of count n is executed (# 14).
The elapsed time for calculation corresponds to the time interval between adjacent ones at the time when the basket feed command is generated.

In the average calculation process, an average of time intervals between adjacent ones at the time of occurrence of six basket feed commands, that is, an average elapsed time that is an average of five elapsed times for calculation is obtained.
By the way, there are cases where there are no 6 basket feed command generation points immediately after installing the elevator for small parcels. Therefore, as the initial information, 6 basket feeds are sent at regular time intervals (1 hour interval). The time of command generation is set in advance.

  If it is determined in step # 12 that there is no basket feed command, it is determined whether or not 60 minutes (one hour) have elapsed since the last time the basket feed command was generated and the average calculation process was executed. (# 15) If 60 minutes (1 hour) has elapsed, it is assumed that the basket feed command has been issued 60 minutes (1 hour) after the previous basket feed command has been issued. Processing for determining the elapsed time for calculation is performed (# 16), and then the average calculation processing in step # 14 is executed.

  After performing the average calculation process of step # 14 or when it is determined in step # 15 that 60 minutes (one hour) has not elapsed since the basket calculation command was previously issued and the average calculation process was executed Therefore, it is determined whether or not the count value n is 3 (# 17). If the count value n is not 3, the process proceeds to step # 11.

If it is determined in step # 17 that the count value n is 3, processing is performed to set the count value n to 0 (# 18), and then the average (average elapsed time) for all floors Among these, the process of setting the floor having the smallest value as the standard stop floor as the standard stop position is executed (# 19), and then the process proceeds to the next automatic return process.
By the way, the average (average elapsed time) at the already set reference stop position (reference stop floor) and the newly calculated average (average elapsed time) for a floor different from the reference stop position (reference stop floor) In the present embodiment, the reference stop position (reference stop floor) is changed to a floor different from the already set reference stop position (reference stop floor).

As shown in FIG. 8, in the automatic return process, first, it is determined whether or not the return timer is being counted (# 21). It is determined whether or not the entrance / exit door 11 is closed (# 22), and if the cage K is stopped and the entrance / exit door 11 is closed, the floor where the cage K is stopped is the reference. It is determined whether or not it is a stop position (reference stop floor) (# 23).
If it is determined in step # 23 that the floor where the basket K is stopped is not the reference stop position (reference stop floor), the return timer starts counting (# 24), and then the process proceeds to the information reading process. It will be.

  Further, if it is determined in step # 22 that the basket K is not stopped or the entrance door 11 is not closed, or the floor in which the basket K is stopped in step # 23 is the reference stop position. When it is determined that it is (reference stop floor), the process proceeds to information reading processing.

  If it is determined in step # 21 that the return timer is being counted, it is determined whether or not the entrance door 11 is closed (# 25), and the entrance door 11 is not closed. If it is determined that the door 11 has been opened, the process proceeds to a count stop process in step # 27.

  If it is determined in step # 25 that the entrance door 11 is closed, whether or not the target stop position has been commanded by operating the operation button 20 of the operation panel S on each floor, that is, an elevation command is issued. It is determined whether or not a command has been issued (# 26), and if a lift command has been commanded (the lift command is present), a count stop process for stopping the return timer and resetting the count value is executed. (# 27) Then, the process proceeds to the information reading process.

If it is determined in step # 26 that an up / down command has not been issued (no up / down command), is the return timer time longer than the set standby time set by the operation unit N? It is determined whether or not (# 28), and if not large, the process proceeds to the information reading process.
If it is determined in step # 28 that the return timer time is greater than the set standby time, first, the count value of the return timer is reset (# 29), and then whether or not the learning setting state is set. Discriminate (# 30).

If the determination result in step # 30 is in the learning setting state, the raising / lowering of the cage K to the reference stop position (reference stop floor) set in the reference stop position learning process is set (# 31). When the learning setting state is not set, that is, when the forced setting state is set, the raising and lowering of the basket K to the reference stop position (reference stop floor) set by the reference stop position setting button F is set. (# 32) Then, the process proceeds to the information reading process.
Incidentally, when raising / lowering is set in step # 31 and step # 32, the basket K is raised / lowered to the reference stop position (reference stop floor) in the raising / lowering control process of step # 2 based on the setting. become.

Hereinafter, it will be described how the reference stop position is set by the reference stop position learning process on the assumption that the cage K is moved up and down in the form shown in FIG.
Incidentally, FIG. 9 shows that in the first time zone T1 from 11:30 to 13:00, the dishes are transported from the kitchen on the first floor to the second and third floors, and from 14:00 to 15:00. In 2 hours T2, used containers are transported from the 2nd and 3rd floor bar to the 1st floor kitchen. In the 3rd time zone from 17:00 to 19:30, from the 1st floor kitchen. Dishes are transported to the 2nd and 3rd floor serving locations, and in the second time zone T4 from 20:00 to 21:30, used containers from the 2nd and 3rd floor serving locations are on the 1st floor kitchen. This is an example of the case where it is assumed that it is transported to the printer, and this is repeated.
In FIG. 9, the conveyance source is indicated by a black circle.

And in order to make it easy to understand the state of raising and lowering of the basket K in each of the first to fourth time zones T1 to T4, the raising and lowering situation of the basket K is indicated by a solid line, but this description correctly describes the number of times of raising and lowering. The outline of the raising / lowering state of the basket K is not shown.
In addition, assuming that the second floor is a floor where ordinary customers are greeted and the third floor is a floor where reservation customers are greeted, the number of times of raising and lowering the basket K between the first floor and the second floor is 1 The case where the frequency | count of raising / lowering of the cage | basket K between a floor and the 3rd floor is few is illustrated.
In each of the first to fourth time zones T1 to T4, for example, also in the first time zone T1, used containers are transported from the second and third floors to the first floor kitchen. Actually, various forms of conveyance are performed, but in this description, it is assumed that only the conveyance based on the above assumption is performed.

The elapsed time from the end of the fourth time zone T4 to the first time zone T1 is 13 hours 30 minutes, and the state where the basket feed command is not commanded is the set allowable time (1 hour). Then, since the basket feed command is generated after the set occurrence time (1 hour) after the previous basket feed command is generated, the average as the occurrence frequency is obtained, so the start time of the first time period T1 The average as the occurrence frequency of each floor in is 60 minutes.
In other words, there are five time intervals between adjacent ones at the six occurrence points, but since the five time intervals are all 60 minutes, the average occurrence frequency is 60 minutes.

  Then, in the first time period T1, when the cooking is started from the kitchen on the first floor to the second and third floors, the average frequency of occurrence on the first floor is less than 60 minutes. The floor will be set to the reference stop position.

  Further, it is assumed that the average frequency of occurrence of the first floor is set to 3 minutes at the end of the first time zone T1, and the basket feed command is given in the first time zone T1 on the second and third floors. Assuming that no occurrence occurs, the average frequency of occurrence is 60 minutes.

Since the elapsed time from the end time of the first time zone T1 is 1 hour at the start time of the second time zone T2, the average as the occurrence frequency of the first floor is 60 in one of the five time intervals. Since the remaining four time intervals are 3 minutes, 72 minutes, which is the sum of the five time intervals, is divided by 5 to obtain 14.4 minutes.
On the second and third floors, since the basket feed command is not generated in the first time zone T1, as described above, the average frequency of occurrence is 60 minutes.

  In the second time zone T2, it is assumed that the transport from the second floor serving place to the first floor kitchen is started and the transport is performed at intervals of 3 minutes. Assuming that the first transport is 3 minutes after the last time that the basket feed command was considered to be generated, as shown in FIG. .6 minutes, and the second transport has an average frequency of occurrence of 37.2 minutes, and the third transport has an average frequency of occurrence of 25.8 minutes. The average frequency of occurrence is 14.4 minutes, and the second floor is set as the reference stop position (reference stop floor).

  Although description is omitted, as described above, when the first time zone T1 is started, the first floor is set as the reference stop position (reference stop floor), and when the second time zone T2 is disclosed, the second floor is In the same way as the reference stop position (reference stop floor) is set, after the second time period T2 ends, when the third time period T3 starts, the first floor becomes the reference stop position (reference stop floor). When the fourth time zone T4 is started after the end of the third time zone T3, the second floor is set as the reference stop position (reference stop floor).

Therefore, in each of the first time zone T1 to the fourth time zone T4, as described above, the stop position that is frequently used as the conveyance source is automatically set as the reference stop position, and the reference stop is performed. The basket K is automatically returned to the position.
Incidentally, as described above, the form illustrated in FIG. 9 is given as an example for explaining the setting of the reference stop position and is different from the actual one, but the reference stop is also performed in the actual operation. It is clear that the position is automatically set and the car K is automatically returned to the reference stop position.

[Another embodiment]
Hereinafter, other embodiments are listed.

(3) In the above embodiment, the setting selection condition in the reference stop position learning process is defined as a condition for selecting the time point when the set number of basket feed commands are generated, and the occurrence frequency is arranged in time series in the reference stop position learning process. Although the case where the average of the time interval between adjacent things at the time of occurrence of the set number of basket feed commands is illustrated, various setting selection conditions can be changed, and the required occurrence frequency can be changed accordingly.
For example, the setting selection condition is defined as a condition for selecting a time point at which a basket feed occurs within a set time (for example, 1 hour or 2 hours) retroactive from the present time, and the occurrence frequency is set to a set time (for example, 1 hour or 2 hours) ) May be used to determine the number of times the basket feed command is present.

(4) As described in the above embodiment, in the case of obtaining the average time interval between adjacent ones at the time of occurrence of the set number of basket feed commands arranged in time series as the occurrence frequency in the reference stop position learning process, It is not necessary to memorize all the time points when the set number of car feed commands are generated, and memorize the average of the time intervals between adjacent ones at the time of occurrence of the set number of car feed commands and the time of the last occurrence time Then, when a car feed command is generated next, an average of time intervals between adjacent ones at the time when the set number of car feed commands are generated can be obtained.
In other words, since the time interval between adjacent ones at the time of occurrence of the set number of basket feed commands is equal to the number obtained by subtracting 1 from the set number, When it occurs, add the elapsed time from the time of the last occurrence to the time when the basket feed command is newly generated to the value obtained by multiplying the stored average by the number obtained by subtracting 2 from the set number Then, by dividing the added value by the number obtained by subtracting 1 from the set number, the average of the time intervals between adjacent ones at the time when the set number of basket feed commands is generated can be obtained.
