Description

  The present invention relates to a moving shelf device in which a plurality of shelves are arranged and used in a collective manner, and more particularly to a lighting device for a work passage formed between the shelves.

  A mobile shelf device configured by arranging a plurality of mobile shelves in a collective and discrete manner forms a work path having a width necessary only on the front surface of the mobile shelf to which goods are to be taken in and out, and other mobile shelves are assembled. Space utilization efficiency is increased. Since the mobile shelf device is used indoors and is used in a state where a plurality of shelves are densely packed, the illuminance in the work passage tends to be insufficient even when a lighting lamp is installed indoors. is there. Therefore, each moving shelf is provided with an illuminating lamp that illuminates the work passage when a work passage is formed in front of the front door, that is, the article insertion / removal opening.

  Primitive lighting on / off control of the moving shelf device is performed by turning on the lighting lamp that illuminates the work passage if a working passage having a predetermined width or more is formed between the moving shelves. If it becomes narrower than the width | variety, the said illumination lamp will be extinguished. However, according to such primitive lighting / extinguishing control, even if no work is being performed in the work passage, the illumination lamp continues to be lit as long as the work passage is formed, so that power is wasted. There is.

  Therefore, various ideas have been made so that the illuminating lamp does not continue to turn on unnecessarily. The invention described in Patent Document 1 is one of them, and when the first predetermined time (for example, 20 minutes) elapses without any movement of the moving shelf, the power supply to the illumination lamp is stopped and turned off, and the second predetermined time continues. The present invention relates to a shelf facility configured to cut off power supply to a movable shelf when it has elapsed.

  According to the invention described in Patent Document 1, the power consumed by the illuminating lamp can be reduced to some extent. However, even if a state where the movable shelf is not operated at all continues, the illumination lamp continues to turn on unnecessarily until the first predetermined time elapses. Alternatively, there is a problem in that the illumination lamp is turned off when the work for putting in and out the article is continued for the second predetermined time or more in the formed work passage. In addition, since the power supply is shut off after the second predetermined time has elapsed, an operation to restore the power supply is necessary, and the operation is difficult.

  In order to avoid the above problems, if a person or a work cart enters the formed work passage, turn on the light, and if a person or work cart leaves the work passage, turn on the light. It can be considered to be configured to be turned off. The invention described in Patent Document 2 is an example, and an entry / exit detection means for entering and exiting a work passage using a photoelectric sensor, and a count storage means for counting and storing the number of entry / exit detections by the entry / exit detection means. If the above count value is a value that a person has entered the work passage, the passage lock is applied and the passage illumination light is turned on. When the entry and exit count values match, the passage lock is released. The passage lighting is turned off.

  According to the invention described in Patent Document 2, since the passage illumination lamp is turned on only when there is a person in the work passage, waste of power consumption can be eliminated. The entry / exit detection means is composed of two photoelectric sensors arranged in the direction of travel to the work passage at the entrance to the work passage, and the work passage is related to the temporal relationship of detection signals from the two photoelectric sensors. Detects entry / exit to / from. However, the entry / exit detection means comprising two photoelectric sensors is inferior in the reliability of the detection result. That is, if two people enter and exit the work path at the same time, the photoelectric sensor may mistakenly detect that one person is entering or leaving, and even if one person enters or exits, the torso and arm may be detected separately. This is because a plurality of humans may be erroneously detected as having entered or exited.

  In addition to the conventional examples described in Patent Documents 1 and 2, a moving shelf apparatus that operates as follows is generally used. That is, when an operation switch is operated to form a work path at a desired position, an illumination lamp that lights the work path to be formed is turned on at the same time as the operation switch is operated, and the movable shelf Moves to form a working path at a desired position. When the interlock is released to make it possible to form a work path at another position, the illumination lamp is turned off. After releasing the interlock, when a person or the like enters the already formed work passage, the entrance sensor is activated to enter the interlock state, and the illumination lamp is turned on again.

  According to the above-described conventional moving shelf device that is generally used, there are the following technical problems.

  (1) After the work in the work passage is completed, it is necessary to operate a switch for releasing the interlock in order to turn off the passage illumination lamp, but this switch operation may be forgotten.

  (2) When a passage is formed at a plurality of locations, it is necessary to maintain the interlocked state and maintain each work passage. Therefore, the lighting of the passage where the work is completed continues to be lit and power is wasted. Is done.

  (3) Even if it is necessary to simply move the moving shelf without performing the work of putting in / out the article to / from the moving shelf, the illumination light of the formed work passage is turned on, and power is wasted.

  (4) When an illuminating lamp is used, such as a fluorescent lamp, that requires time from switch-on to lighting, the worker cannot search for stored items from switch-on to lighting. The moving shelf may pass in front of the operator before it lights up.

  (5) In the case where the illumination lamp is turned on after the operation of forming the work path is completed, when the installation environment of the moving shelf device is dark, it is not possible to confirm the stored articles on the moving shelf facing the work path being formed. . Therefore, if the work path is not the target work path after the work path is formed, the work path forming operation needs to be performed again at another position, so that the work path cannot be formed quickly and accurately.

  (6) In the case of a moving shelf in which an illumination lamp is turned on as soon as an operation switch is operated to form a work path, there is an advantage that the stored articles on the moving shelf facing the work path being formed can be confirmed. However, there is a drawback that power is wasted on the lighting.

JP 2004-35233 A JP-A-11-99821

  The present invention makes it possible to check stored articles on a moving shelf facing a work path that is being formed even when the installation environment of the moving shelf device is dark, and avoids waste of electric power due to an illumination lamp. An object of the present invention is to provide a mobile shelf device capable of performing the above.

It has the most important feature.

  When the passage width detecting device detects that the passage width has become equal to or larger than the predetermined width during the operation passage forming operation, the time measuring unit starts measuring time and the control unit turns on the illumination lamp for a predetermined time and turns it off. Therefore, for example, even if the moving shelf device is installed in a dark place, the passage illumination lamp is temporarily turned on while the passage is being formed, and the stored items on both sides of the passage being formed can be confirmed. As a result of checking the stored item, if the passage is going to be formed at an undesired position, the passage formation can be stopped and the passage can be formed at another position, so that the efficiency of the operation of putting in / out the stored item can be improved. it can. Since the lighting of the illuminating lamp is temporary, the power consumed by the illuminating lamp can be saved.

  Hereinafter, various embodiments of the movable shelf device according to the present invention will be described with reference to the drawings. In the present specification, the “work path” refers to a path formed between the moving shelves and having a sufficient width that does not hinder the work for putting in and out the article. The “predetermined width” in the case of “whether or not the passage is greater than or equal to a predetermined width” refers to a width of a passage formed during the operation passage forming operation and narrower than the work passage. . The reference of the “predetermined width” is, for example, a width that allows the illumination lamp supported above the movable shelf to be visually recognized.

  The movable shelf apparatus according to the present invention can be applied to both an electric movable shelf and a manual movable shelf. FIG. 1 and FIG. 2 each show an example in which the present invention is applied to an electric moving shelf, and each shows an example in which three moving shelves 1 are arranged in a discrete manner on the floor. Each moving shelf 1 shown in FIG. 1 and FIG. 2 has a surface in a direction orthogonal to the paper surface as a loading / unloading surface of an article, that is, a frontage surface, and a surface of the side panel 13 arranged in a direction perpendicular to the frontage surface. Is drawn as the front. Each movable shelf 1 can be moved in a direction parallel to the surface of the side panel 13, that is, a direction orthogonal to the front surface by a traveling wheel (not shown) and a motor that rotationally drives the traveling wheel.

  The example shown in FIGS. 1 and 2 is an example in which a work path is formed between the leftmost movable shelf 1 and the second movable shelf 1 from the left end, and extends obliquely upward from the leftmost movable shelf 1. An illuminating lamp 3 that illuminates the passage is supported by an arm. The illumination lamps 3 are provided on the respective movable shelves 1 as described above, but depictions other than the illumination lamps 3 supported by the leftmost movable shelf 1 are omitted. On the side panel 13 of each movable shelf 1, an operation switch 11 for instructing a right turn and an operation switch 12 for instructing a left turn are incorporated. In the example shown in FIGS. 1 and 2, a control unit 2 is incorporated in the leftmost movable shelf 1. The control unit 2 is also incorporated in other movable shelves, but the illustration is omitted. The control unit 2 performs control such as movement of the movable shelf 1, interlock, blinking of the passage light.

  The difference between the example shown in FIG. 1 and the example shown in FIG. 2 is the difference in the passage width detection device. The passage width detection device detects that the passage formed between the adjacent movable shelves 1 has become a predetermined width or more. In the example shown in FIG. 1, the passage width detection device 4 includes a distance sensor. In the example shown in FIG. 2, the passage width detecting device 5 uses a swing arm. The distance sensor detects, for example, a time delay of ultrasonic waves that are reflected from the opposing movable shelf 1 and returned by emitting ultrasonic waves toward the opposing movable shelf 1. A detection signal from the distance sensor is processed by a passage width detection unit described later, and a passage width D is detected.

  The passage width detection device 5 shown in FIG. 2 is mainly composed of a swing arm 51 and a switch 55, as shown in FIG. At both left and right end portions on the top plate 14 of the movable shelf 1, one end portion of the swing arm 51 is attached to be rotatable in a plane parallel to the surface of the top plate 14 and thus in a horizontal plane. The tip of the swing arm 51 extending obliquely from one movable shelf 1 toward the other movable shelf 1 rotates in the horizontal plane with the tip of the swing arm 51 extending diagonally from the other movable shelf 1. Connected as possible. Therefore, the rotation angle of the swing arm 51 changes according to the interval between the movable shelves 1 facing each other. When the moving shelves 1 facing each other are close to each other, the swinging arms 51 extending from both the moving shelves 1 are close to each other, and the angle around the connecting portion of the swinging arms 51 is acute. Thus, the angle increases as the distance between the moving shelves 1 facing each other increases.

  Of the swing arms 51 at both the left and right ends of the movable shelf 1, a switch pressing member 56 is fixed near the base end of one swing arm 51. The operation button of the switch 55 is located within the movement range. When the interval between the moving shelves 1 facing each other is narrower than the predetermined interval, the switch pressing member 56 presses the operation button of the switch 55, and when the interval between the moving shelves 1 facing each other becomes larger than the predetermined interval, the switch pressing member 56. The operation button of the switch 55 is adjusted so as to be released. An on / off switching signal for the switch 55 is input to a passage width detector described later.

  The swing arm 51 which is a main constituent member of the passage width detecting device 5 shown in FIG. 3 also serves as a cable support member that electrically connects between adjacent movable shelves. That is, the swing arms 51 that extend from adjacent movable shelves and are rotatably connected to each other are formed in a channel shape except for the connecting portion, and the cable 58 is passed through the channel-like portion. The cable 58 is used for exchanging signals between adjacent movable shelves and supplying power.

  Although the appearance of a manual moving shelf to which the present invention can be applied is not shown, it can be applied to a conventionally known manual moving shelf. For example, a movable handle can be moved by providing a handle that can be rotated on the side panel of each movable shelf and transmitting the manual rotational force of the handle to the traveling wheels via a speed reduction mechanism. You may have done. Alternatively, in the case of a small-sized moving shelf device, the moving shelf may be directly moved by manually pushing or pulling.

  Next, various embodiments of the work passage lighting device in the moving shelf device will be described. Some examples of the electric movable shelf include a novel interlock method, but the interlock method applied to the present invention is similar to the interlock method in the conventional electric movable shelf, An interlock may be applied when an operation switch for forming a passage is operated, and operation of operation switches other than the operation switch may be invalidated.

  FIG. 4 shows an embodiment in which a distance sensor is used as a passage width detection device in an electric moving shelf. In FIG. 4, the control unit 2 can be configured mainly by a microcomputer or a microprocessor that are grouped on, for example, a single circuit board and programmed to perform the functions indicated by a plurality of blocks. Alternatively, an IC, a logic circuit, a relay circuit, or the like that performs each function can be used. The control unit 2 includes an interlock unit 21, a lighting maintenance unit 22, a motor driving unit 24, a set time lighting unit 23, a timer unit 25, and a passage width detection unit 41.

  The control unit 2 includes the operation switch 11, the operation switch 12, a drive motor 30 that drives the movable shelf, an ultrasonic sensor 4 as a passage width detection device, and an operator who enters a passage formed between adjacent movable shelves. An ingress sensor 60 that detects an object such as an illumination relay 26 that causes the lighting lamp 3 to blink is connected as an external connection member. While the operation switch 11 is being operated, the motor driving unit 24 drives the motor 30 so that the moving shelf moves toward the right. While the operation switch 12 is being operated, the motor driving unit 24 drives the motor 30 so that the moving shelf moves toward the left. When the operation of the operation switch 11 or the operation switch 12 is stopped, the driving of the motor 30 is stopped and the moving shelf is stopped.

  As the moving shelf is driven and the interval between the adjacent moving shelves increases, the detection signal of the passage width detecting device including the ultrasonic sensor 4 changes, and the passage width detecting unit 41 calculates the detection signal, thereby Detects the distance from the moving shelf in real time. When the interval between the adjacent moving shelves reaches a preset passage width, the passage width detection unit 41 activates the illumination relay 26 to turn on the illumination lamp 3 and at the same time starts the time measurement by the time measurement unit 25. The time measured by the time measuring unit 25 is preset by the set time lighting unit 23, for example, 10 seconds, and the illumination lamp 26 is lit for the preset time, and when the set time elapses, the illumination relay 26 Is operated to turn off the illumination lamp 3.

  The lighting operation of the illuminating lamp 3 is supported before the passage between the moving shelves is sufficiently opened, that is, a passage width that is narrower than the width of the work passage necessary for the work of putting in and out the articles, for example, above the moving shelf. This is done when a predetermined width is reached such that the illuminating lamp is visible. Therefore, even if the moving shelf device is installed in a dark environment, it is possible to visually confirm articles, empty spaces, etc. stored in the moving shelf facing the passage by temporarily turning on the lighting lamp 3. it can. If a passage is being formed at a desired position, the passage formation operation may be continued as it is. If the position of the passage being formed is not the desired position, the passage formation operation is stopped and moved to another position. What is necessary is just to operate to form a working path. In the operation of forming the work passage in another position, when the passage illuminated by the temporary lighting of the illumination lamp 3 is narrower than the predetermined width, the once illuminated illumination lamp 3 is turned off.

  In the present embodiment, as described above, the interlock is not applied only by operating the operation switch 11 or 12 to form a passage between the moving shelves. In this respect, it is different from the configuration in which the interlock is applied from the time when the operation switch is operated like the conventional electric moving shelf. Therefore, even if the passage forming operation is stopped in the middle of the passage forming operation as described above and the passage is to be formed at another position, the passage is immediately formed at another position without performing the operation of releasing the interlock. Can be performed.

  When a work path having a width necessary for putting in and out the article is formed at a desired position, the operation of the operation switch 11 or 12 is stopped, and the driving of the motor 30 by the motor driving unit 24 is stopped to move the moving shelf. Stop. At this point, the interlock is not yet applied. When an object such as a person or a trolley enters the work passage, the entry sensor 60 detects this, and the interlock unit 21 is interlocked only by this detection signal. The interlock in this case means that the movement of the movable shelf is restricted even if the operation switch 11 or 12 of another shelf is operated to form a work path at another position. If the interlock part 21 applies an interlock, the lighting maintenance part 22 will operate the illumination relay 26, and will light the illuminating lamp 3. FIG.

  The lighting maintaining unit 22 is configured such that when the time measuring unit 25 is measuring a predetermined time, and thus the illumination lamp 3 is temporarily lit, a work passage is formed and the locking device, that is, the interlock unit 21 is connected to the moving shelf. When the movement is restricted, the lighting lamp 3 is kept on even if the time measuring unit 25 times up. When a person, a carriage, or the like leaves the work passage, the detection signal from the approach sensor 60 is interrupted, the interlock unit 21 releases the interlock, and the lighting maintenance unit 22 reverses the illumination relay 26 to turn off the illuminating lamp 3.

  As a modification of the above embodiment, the interlock by the interlock portion 21 and the release thereof may be performed by operating an interlock operation member. The interlock operation member may be a dedicated operation member, or the operation members 11 and 12 may also serve as the interlock operation member. When the operation members 11 and 12 also serve as an interlock operation member, when the operation member 11 or 12 of one moving shelf is operated and a passage is formed, another operation member 11 or 12 is operated. It is a case where it is comprised so that an interlock may be applied when it is carried out. In the case of this modified example, the interlock is not applied even when entering the formed work passage in the state where the interlock is not applied, and the interlock is applied by operating the interlock operation member. Lights up. When the interlock operation member is operated to release the interlock, the passage illumination lamp 3 is turned off, and a work passage can be formed at another position.

  FIG. 5 shows an embodiment in which a passage width detection switch is used as a passage width detection device in an electric moving shelf. The embodiment shown in FIG. 5 includes a passage width detection switch 55 used in the passage width detection device 5 of the swing arm type shown in FIG. 3 instead of the ultrasonic sensor 4 in the embodiment shown in FIG. . The other internal configuration of the control unit 2 is the same as the internal configuration of the control unit 2 in the embodiment shown in FIG. The external connection member connected to the control unit 2 is also substantially the same as the embodiment shown in FIG. 4 except that the left communication line and the right communication line are connected. The left communication line is connected to the control circuit of the left moving shelf, and transmits a right signal from the left moving shelf, and transmits a left signal to the left moving shelf. The right communication line is connected to the control circuit for the right moving shelf, and transmits a left-handed signal from the right moving shelf, and transmits a right-handed signal to the right moving shelf.

  As with the operation switches 11 and 12 in the embodiment shown in FIG. 4, the operation switch 11 and the operation switch 12 move toward the right or left while the operation is being performed, and stop the operation. The movable shelf may be configured to stop, or the movable shelf may be configured to move until an operation path is formed once operated. In any case, when the operation switch 11 is operated, a rightward signal is generated to move the shelf to the right, and the generated rightward signal is transmitted to the right shelf to move the right shelf to the right. Further, when the operation switch 12 is operated, a leftward signal is generated and the shelf is moved to the left, and the generated leftward signal is transmitted to the left shelf and the left shelf is moved to the left. Has been. A rightward signal or a leftward signal is transmitted to a movable shelf that needs to move, and the movable shelf to which the rightward signal or the leftward signal is transmitted is driven right or left by the motor 30.

  In this embodiment, the shelf starts to move by operating the operation switch 11 or 12, and the passage width detection switch 55 is activated when the passage width between the moving shelves being formed reaches a preset width. When the switch 55 is activated, the passage width detection unit 41 activates the illumination relay 26 to turn on the illumination lamp 3 and at the same time, the timing by the time measuring unit 25 is started. The subsequent operation is the same as that of the embodiment shown in FIG. 4, and the illumination lamp 3 is turned on and then turned off only while the time measuring unit 25 measures, for example, 10 seconds. The movement stops when a work path having a width necessary for work is formed between adjacent shelves. Further, when an object enters the work passage, the approach sensor 60 detects this, and the interlocking unit 21 applies the interlock, and at the same time, the lighting maintaining unit 22 turns on the illuminating lamp 3 via the illumination relay 26. When the illumination lamp 3 is temporarily lit along with the time measurement of the time measuring unit 25, the lighting maintaining unit 22 forms a work path and the interlock unit 21 restricts the movement of the moving shelf, the time measuring unit 25. Even if the time is up, the lighting 3 is kept on. Also in this embodiment, the same effect as that of the embodiment shown in FIG. 4 can be obtained.

  The embodiment shown in FIG. 6 is the embodiment shown in FIG. 5 except that the passage width detecting device is replaced with the ultrasonic sensor 4 and that the illumination relay 26 and the illumination lamp 3 are provided on the left and right sides of the movable shelf. Is the same. Therefore, a right-handed signal and a left-handed signal are transferred from the adjacent moving shelf via the communication line. The ultrasonic sensor 4 is the same as the ultrasonic sensor 4 of the embodiment shown in FIG. When the illumination lamps 3 are provided on the left and right of the movable shelf as in this embodiment, the illumination lamp 3 on the side facing the passage that is being formed by the movement of the movable shelf is turned on. The illumination lamp 3 on the side facing the passage is turned on under the control of the respective control units 2 on the moving shelves on opposite sides of the passage.

  Next, an embodiment in which the passage illumination device is applied to a manual moving shelf will be described with reference to FIG. The manual moving shelf does not include an operation switch, a motor, a driving unit thereof, an interlock unit, and the like. The blinking control of the illumination lamp in the passage formed between the moving shelves is configured to be performed in the same manner as in the case of the electric moving shelves. In FIG. 7, the control unit 2 includes a lighting maintenance unit 22, a set time lighting unit 23, and a timer unit 25. The controller 2 is connected to the passage illumination lamp 3, the passage width detection switch 55, and the lock operation unit 62 as external connection members. The lock operation unit 62 is configured to mechanically lock the movement shelf so that the movement shelf is not moved after the movement path is formed by the movement of the movement shelf, and includes the lock operation unit 62. The switch is switched between when the lock operating member 62 is in the locked position and when it is in the unlocked position, and a switch switching signal is input to the control unit 2.

  The operation unit 32 illustrated in FIG. 7 corresponds to a handle that is rotated by a manual force, for example. Reference numeral 34 denotes a drive mechanism for moving the movable shelf, and the drive mechanism 34 includes a speed reduction mechanism that transmits the rotational driving force of the handle to the traveling wheels and the traveling wheels.

  When the operation unit 32 is operated to activate the drive mechanism 34, the movable shelf can be moved to the right or left. Along with the movement of the movable shelf, a work path is formed between the opposite sides of the movable shelf on one side of the left and right front surfaces. In the process of forming the work passage, when the passage width becomes a predetermined passage width narrower than the width of the work passage, the passage width detection switch 55 is actuated, and this operation signal is input to the control unit 2. In the control unit 2, the timer 25 is activated by the operation signal of the passage width detection switch 55 and at the same time, the set time lighting unit 23 is operated to turn on the illuminating lamp 3 through an appropriate driving member, for example, a relay. The lighting time of the illuminating lamp 3 is set in advance by, for example, about 10 seconds by the set time illuminating unit 23. When 10 seconds have elapsed, the illuminating lamp 3 is turned off based on the time measurement of the time measuring unit 25. The reason why the illumination lamp 3 is temporarily turned on during the formation of the work passage is as described in the above embodiment.

  Even after the illuminating lamp 3 is temporarily turned on and off during the formation of the work passage, the movement of the movable shelf is continued, and when the work passage having a width necessary for working is formed, the operation of the operation unit 32 is stopped. Stop moving shelves. Before a person or the like enters the formed work passage, the moving shelf is mechanically locked by operating the lock operation unit 62 so that the moving shelf does not move freely. A lock signal is input from the lock operation unit 62 to the control unit 2, and the control unit 2 turns on the illumination lamp 3. When the illumination lamp 3 is temporarily lit along with the time measurement of the time measuring unit 25, the lighting maintaining unit 22 operates when the lock operation unit 62 is operated and the lock device restricts the movement of the moving shelf. Even if the time is up, the lighting 3 is kept on.

  As described above, also in the present embodiment in which the passage lighting device is incorporated in the manual moving shelf device, the same effect as that in the embodiment in which the passage lighting device is incorporated in the above-described electric moving shelf device can be obtained.

  Next, several blinking control operation examples of the passage lighting device in the moving shelf device according to the present invention will be described with reference to FIGS. In FIG. 8, FIG. 9, and FIG. 10, the reference numerals like S21, S22, S23,.

  The operation example shown in FIG. 8 is a blinking operation of a passage illumination lamp applicable to a conventional electric moving shelf that is interlocked by operating an interlock operation member, for example, an operation member for forming a work passage. It is an example. First, it waits for passage operation to be performed in step 21. When the passage forming operation is performed, the interlock is applied (S22), and the operation of forming the work passage at the designated position is started. In the moving shelf facing the work passage being formed, it is determined whether or not a predetermined passage width has been reached based on a signal from the ultrasonic sensor 4 or the passage width detection switch 55 (S23). The “predetermined passage width” in this case is a passage width that is smaller than the work passage width necessary for putting in and out the article and is such that an article stored on the moving shelf facing the passage being formed can be visually recognized. .

  When the predetermined passage width narrower than the work passage width is reached during the operation passage forming operation, the timer, that is, the time counting by the timer 25 is started, and the illumination lamp for illuminating the passage is turned on (S24). The time measured by the timer is set to a relatively short time such as 10 seconds, for example, and when the timer expires (Yes in S25), the illumination lamp is turned off (S25). Therefore, the lighting of the illuminating lamp is temporary, and during this time, the contents of the moving shelf facing the passage that is being formed can be visually recognized from the outside of the moving shelf. If the visually observed item is the intended item, it is sufficient to continue the passage formation work. If it is not the intended item, the passage formation operation is stopped and the operation is again performed to form the operation passage in another position. Good.

  The passage forming operation is continued even if the illumination lamp is temporarily turned on and then turned off, and when a work passage having a width necessary for the work for putting in / out the article is formed (Yes in S26), the formed work passage is then formed. It is determined whether a person or other object has entered (S27). This determination is made by the control unit 2 based on the output signal of the ingress sensor 60. When it is detected that an object has entered the work passage, the passage illumination lamp is turned on (S28). The lighting operation of the passage illumination lamp is maintained until it is determined that the interlock is released in the determination step S29 for determining whether or not the next interlock is released. When the interlock is released, an operation for forming the work path in another place becomes effective, and the work path can be formed in another place by this operation. When the interlock is released, the illumination lamp is turned off (S30), and the operation ends.

  In step S27, if there is no entry into the work path, it is determined whether or not an operation for forming the work path at another position is performed (S35). Is canceled (S36), and the operation is terminated. When the operation for forming the work passage is not performed at another position, the process returns to the passage entry determination step (S27).

  If it is determined in step S25 whether the time is up or not, the process proceeds to step S31 to determine whether or not the passage has been completed. If the passage has not been completed, the process returns to step S25 to end the passage. If it has reached, the process proceeds to step S32 for determining whether or not the next time is up. When the time is up, the process proceeds to the turn-off step S25. If the time has not been reached, the process proceeds to the passage entry determination step (S33). When it is detected that the vehicle has entered the passage, the lighting is maintained (S34), and the determination step of whether or not the interlock is released (S29). move on. If no passage entry is detected in step S33, the process returns to step S32 for determining whether the time is up. Due to the presence of the above steps S31 to S34, when a wide work passage for article taking-in / out work is formed during the lighting period of the temporary passage illumination lamp and an object enters this passage, Instead of lighting, lighting is continuously maintained.

  According to the operation example shown in FIG. 8, since the passage illumination lamp is temporarily turned on during the work passage formation operation, even if the place where the moving shelf device is installed is a dark place, the passage is being formed. It is possible to check the contents of the moving shelf facing from the side of the moving shelf, and if it is not the desired passage location, the passage formation operation to the next location can be immediately performed. In addition, after the work passage is formed, the passage illumination lamp is not lit unless it enters the work passage, so that unnecessary lighting of the illumination lamp can be prevented.

  Next, the operation example shown in FIG. 9 will be described. This operation example is an aisle lighting device in an electric moving shelf. Even if a work passage forming operation is performed, the interlock is not applied, and the interlock is not activated until the entry into the work passage is detected. This is an example in which a light is turned on. First, in step 41, it waits for the passage forming operation. When the passage formation operation is performed, an operation of forming a work passage at a designated position is started (S42). It is determined whether or not an object such as an operator has entered the passage that is being formed (S43), and if it has entered, the process jumps to step S50 described later. Normally, the vehicle does not enter the passage in the middle of formation, and proceeds to a predetermined passage width determination step in step S44. In this case, the “predetermined passage width” is smaller than the width of the work passage necessary for putting in and out the article, as described above, and the extent that the article stored in the movable shelf facing the passage being formed can be visually recognized. The width of the passage.

  When the predetermined passage width is reached during the operation passage forming operation, the timer, that is, the time counting by the time measuring section 25 is started, and the illumination lamp for illuminating the passage is turned on (S45). When the timer 25 set for a relatively short time of about 10 seconds is up (Yes in S46), the illumination lamp is turned off (S47). In this way, while the illuminating lamp is temporarily turned on, it is possible to visually recognize the stored items on the moving shelf facing the passage.

  After the illumination lamp is turned off in step S47, the process waits for the completion of the formation of the work passage (S48), and then it is determined whether or not an operator or the like has entered the work passage (S49). When there is an entry into the work passage, the interlock is first applied here and the illumination lamp of the work passage is turned on (S50). The lighting of the illuminating lamp and the interlock are maintained until it is determined to exit in the next step of determining whether or not to exit the passage (S51). When it is determined that the passage is leaving, the interlock is released and the illuminating lamp is turned off. (S52), and the operation ends.

  While it is not determined in step S49 that the passage has been entered, it is determined in step S55 whether or not a work passage formation operation has been performed at another position. If a work passage formation operation has been performed at another position, the operation ends. The operation is started from step S41 as a new work path forming operation. If the operation for forming the work path is not performed at another position, the process returns to step S49.

  Since the work passage is formed before the time measuring unit 25 times out and may enter the passage, steps S54 to S58 corresponding to steps S31 to S34 in the operation example of FIG. 8 are provided. If the work passage forming operation is completed before the time is up in step S46 (YES in S53), it is determined again whether the time measuring unit 25 has timed up (S54). If the time is up, the illumination lamp is turned off (S47). If the time has not expired, it is determined whether or not the passage has entered (S55). If there is a passage, an interlock is applied (S56), and the illumination lamp is kept on and the process proceeds to step S51.

  According to the operation example described above, the same effect as that of the operation example shown in FIG. 8 can be obtained, and it is not the first time when the entry into the work passage is detected, but the interlock is not immediately applied in the work passage formation operation. Since the interlock is applied and the interlock is released when the work passage is withdrawn, the operation of forming the work passage at another position after the formation of one work passage can be simplified.

  Next, the operation example shown in FIG. 10 will be described. This operation example is an operation example of the passage illumination device in the manual moving shelf. First, it is determined whether or not the movable shelf is locked so as not to move by the locking device (S61). If it is locked, the process jumps to the passage lighting lamp lighting step S69. If it is not locked, it is determined whether or not the movable shelf is movable (S62). If it is movable, the process proceeds to the next predetermined passage width determination step S63. The “predetermined passage width” in this case is also a passage width that is smaller than the work passage width necessary for taking in and out the articles and is such that the articles stored in the movable shelf facing the passage being formed can be visually recognized.

  When the predetermined passage width is reached during the operation passage forming operation, the timer, that is, the time counting by the time measuring section 25 is started, and the illumination lamp for illuminating the passage is turned on (S64). When the timer 25 set for a relatively short time of about 10 seconds is up (Yes in S65), the illumination lamp is turned off (S66). After the illuminating lamp is turned off, it waits once (S67), and it is then determined again whether or not the movable shelf is locked by the locking device (S68). If it is not locked, the operation is terminated, and if it is locked, the passage illumination lamp is turned on again (S69). The lighting of the illuminating lamp is maintained until it is determined that the lock is released in the next step of determining whether or not the lock is released (S70). When the lock is released, the lamp is turned off (S71) and the operation ends.

  In step S65, it is determined whether or not the time is up. If the time is not yet up, it is determined whether or not the lock state is reached (S72). It progresses to the judgment step (S70) of whether it is cancellation | release. If it is not in the locked state in step S72, the process returns to the step of determining whether the time is up (S65).

  In the case of the above operation example as well, the passage illumination lamp is temporarily turned on during the operation passage forming operation, so it is possible to check the contents of the moving shelf facing the passage being formed, which is not the desired passage location. In the event of a failure, the work path forming work to the next place can be immediately performed. Also, after entering the work passage, when entering the work passage, the passage illuminating lamp will not turn on unless the movable shelf is locked with a locking device to ensure safety for safety, and it will turn off when the lock is released. It is possible to prevent unnecessary lighting of the lamp.

  In any of the embodiments described above, the work passage is formed during the formation of the work passage and the passage lighting is temporarily turned on, and the lock device is locked or the entry to the work passage is detected. And the lighting of the above-mentioned passage lighting is maintained continuously, not temporarily. Therefore, frequent blinking of the illuminating lamp is avoided, and when the work passage is formed, the work passage is illuminated, and the article insertion work can be started simultaneously with the formation of the work passage.

  In any of the embodiments, after the passage 3 being formed has a width greater than a certain value and the illumination lamp 3 is temporarily turned on, the passage is formed to form a work passage in another position. When it is narrower than a predetermined width, the illuminating lamp 3 that is once turned on is turned off.
