The notification status update unit 21d is connected to the system control unit 21a, the own shelf status update unit 21b, the other shelf status update unit 21c, the LED lamp 19, and the voice notification unit 22, and performs notification condition determination and notification timing control. Yes.

  Based on the configuration described above, the operation of the movable shelf device 18 in the first embodiment will be described. The moving shelf device 18 shown in FIG. 5 has six blocks, and has six units 1A, 1B, 1C, 1D, 1E, and 1F as manual moving shelves. A passage 27 is formed between the manual moving shelves 1A and 1B, and a user in the shelf can enter the passage 27. Clearances 28 and 29 that are not as large as the passages are formed between the manual movement shelves 1B-1C and 1C-1D. Each of the gaps 28 and 29 is configured as a gap where a user in the shelf cannot enter. Further, the manual movement shelves 1D, 1E, and 1F are arranged in series, that is, arranged in series.

  In the state shown in FIG. 5, that is, from the state in which a user in the shelf is present in the passage 27, the manual moving shelf 1D, 1E connected by rotating the handle 3 of the manual moving shelf 1F positioned at the right end by the moving shelf user. , 1F collectively to the left, the control unit 21 (referred to as 21D, 21E, 21F) of the manual movement shelves 1D, 1E, 1F receives signals from the movement detection unit 23 and the lock detection unit 25. Based on this, it is recognized that the shelf is moving to the left.

  Next, the control units 21D, 21E, and 21F receive information from the infrared communication unit 26, and recognize that the pyroelectric sensor 20 of the manual moving shelf 1A detects that a user in the shelf exists in the passage 27. To do. At this time, the control units 21D, 21E, and 21F are located on the right side which is the detection side by the pyroelectric sensor 20, rather than the manual movement shelf 1A in which the user in the shelf is detected by the pyroelectric sensor 20. Recognize that 1D, 1E, and 1F are moving. Then, the control unit 21F recognizes the manual moving shelf 1F operated by the shelf moving user as an end of the moving shelf as a group, and the LED lamp 19 of the manual moving shelf 1F blinks red. Let

  Similarly, the control unit 21D recognizes the manual moving shelf 1D as an end of the moving shelf as a group, and blinks the LED lamp 19 of the manual moving shelf 1D in red. The control unit 21E recognizes that the manual moving shelf 1E is not the end of the shelf that is moving as a group, and does not operate the notification unit.

  The control unit 21 (referred to as 21A) of the manual moving shelf 1A that recognizes the user in the shelf receives information from the infrared communication unit 26, and is manually operated by the movement detecting unit 23 of the manual moving racks 1D, 1E, and 1F. It is recognized that manual type moving shelves 1D, 1E, and 1F located on the right side that is the detection side by the pyroelectric sensor 20 are moving from the type moving shelf 1A. Then, the LED lamp 19 of the manual movement shelf 1A that can be recognized by the user in the shelf is blinked in red.

  This notifies both the shelf moving user and the in-shelf user that the manual moving shelves 1D, 1E, and 1F are moving so that the manual moving shelf 1B moves in the direction of narrowing the passage 27. Therefore, it is possible to prevent the occurrence of a problem that a user in a shelf is sandwiched between shelves. At the time of this notification, the control effect can be enhanced by causing the control unit 21A to simultaneously operate the voice notification unit 22 of the manual moving shelf 1A.

  In FIG. 5, when the group of manual movable shelves 1D, 1E, 1F moves to the left and the gap 29 disappears and the manual movable shelf 1D contacts the manual movable shelf 1C, the manual movable shelf 1C also It moves to the left together with a group of manually operated shelves 1D, 1E, 1F. At this time, the manual movement shelf 1C has started to move as the shelf located at the end of the group of manual movement shelves is changed from the manual movement shelf 1D to the manual movement shelf 1C. The control unit 21D is not the end of the shelf in which the manual moving shelf 1D is moving as a group by detecting it with the shelf movement detecting unit 23 of the type moving shelf 1C and giving this information to the manual moving shelf 1D. The LED lamp 19 stops blinking and is turned off. Then, the control unit 21 (21C) of the manual moving shelf 1C determines that the own shelf is the head of the group of moving shelves 1 based on the operation detection of the own shelf and the adjacent information of the manual moving shelf 1D, 1E, 1F. Judgment is made and blinking of the LED lamp 19 of the manual type moving shelf 1C is started.

  Thereafter, similarly, when the group of manual movable shelves 1C, 1D, 1E, 1F moves to the left and the gap 28 disappears and the manual movable shelf 1C contacts the manual movable shelf 1B, the manual movable shelf 1B Move to the left together with a group of manual movement shelves 1C, 1D, 1E, 1F. At this time, as the shelf located at the end of the group of manual mobile shelves is changed from the manual mobile shelf 1C to the manual mobile shelf 1B, the controller 21C controls the manual mobile shelf 1C as described above. The LED lamp 19 is turned off, and the control unit 21 (referred to as 21B) of the manual movable shelf 1B starts blinking of the LED lamp 19 of the manual movable shelf 1B.

  Although the case where the gaps 28 and 29 exist is shown in the first embodiment, the same applies to the case where the manual movement shelves 1B to 1F are continuously provided without the gaps 28 and 29. In this case, the LED lamp 19 of the manual moving shelf 1B blinks instead of the manual moving shelf 1D. Further, in the first embodiment, when the handle lock mechanism 24 of the manual moving shelf 1A is turned on as shown in FIG. 6, this is recognized by the control units 21B, 21C, 21D, 21E, and 21F. The control units 21B, 21C, 21D, 21E, and 21F recognize the locked state of the manual moving shelf 1A, and each moving shelf 1B on the right side that is the side where the pyroelectric sensor 20 of the manual moving shelf 1A is disposed. Since 1C, 1D, 1E, and 1F may move, the controllers 21B, 21C, 21D, 21E, and 21F perform the same operation control as in the first embodiment.

  FIG. 7 shows a second embodiment of the present invention. A passage 30 is formed on the right side of the manual moving shelf 1F, and the inside of the shelf is configured to allow entry of users in the shelf. Clearances 31 and 32 are formed between the manual moving shelves 1E-1F and 1D-1E, respectively. Moreover, the manual type movement shelves 1A to 1D are connected in series. In the second embodiment, the handle lock mechanism 24 of the manual moving shelf 1F that forms the passage 30 is turned on.

  In the state shown in FIG. 7, that is, from the state in which a user in the shelf exists in the passage 30, the manual moving shelf 1 </ b> A to 1 </ b> D connected by rotating the handle 3 of the manual moving shelf 1 </ b> A positioned at the left end by the moving shelf user. Are moved to the right side, the control units 21A, 21B, 21C, and 21D of the manual type moving shelves 1A, 1B, 1C, and 1D automatically move based on signals from the movement detection unit 23 and the lock detection unit 25. Recognize that the shelf is moving to the right.

  Next, the control units 21A, 21B, 21C, and 21D receive information from the infrared communication unit 26, and detect that there are users in the shelf in the passage 30 by the pyroelectric sensor 20 of the manual moving shelf 1F. Recognize At this time, the control units 21A, 21B, 21C and 21D are moved by the manual moving shelf 1A operated by the shelf moving user and the manual moving shelf 1D located at the end of the shelf moving in a group. Recognize that However, since the movement of the manual moving shelf 1F is locked, the control units 21A, 21B, 21C, and 21D are on the opposite side of the manual moving shelf 1F from the right side where the pyroelectric sensor 20 detects the user in the shelf. The movement of each manual movement shelf 1A-1E located on a certain left side is not notified. This is because there is no possibility that the manual movement shelf 1F moves even if each manual movement shelf 1A to 1E moves. Thereby, unnecessary notification at the time of shelf movement locking can be omitted, and usability can be improved.

  FIG. 8 shows a third embodiment of the present invention. A passage 33 is formed between the manual moving shelves 1 </ b> E- 1 </ b> F, and a user in the shelf can enter the passage 33. Clearances 34 and 35 are formed between the manual moving shelves 1D-1E and 1C-1D, and the manual moving shelves 1A to 1C are connected to each other. In the third embodiment, the handle lock mechanism 24 of the manual movable shelf 1F that forms the passage 33 is turned on.

  In the state shown in FIG. 8, that is, from the state in which a user in the shelf is present in the passage 33, the manual moving shelf 1A, 1B connected by rotating the handle 3 of the manual moving shelf 1A located at the left end by the moving shelf user. , 1C are moved to the right as a whole, the control units 21A, 21B, 21C of the manual type moving shelves 1A, 1B, 1C have their own shelves based on signals from the movement detecting unit 23 and the lock detecting unit 25. Recognize that it is moving to the right. The control units 21A, 21B, and 21C recognize the locked state of the manual movement shelf 1F, and move each of the right side movements on the side where the pyroelectric sensor 20 of the manual movement shelf 1E is disposed rather than the manual movement shelf 1F. Since the shelves 1A, 1B, 1C, 1D, and 1E may move, the control unit 21A causes the LED lamp 19 of the manual moving shelf 1A operated by the shelf moving user to blink red. Similarly, the control unit 21C recognizes the manual moving shelf 1C as an end of the moving shelf as a group, and blinks the LED lamp 19 of the manual moving shelf 1C in red. The control unit 21B recognizes that the manual movement shelf 1B is not the end of the shelf that is moving as a group, and does not operate the notification unit.

  The control unit 21E of the manual movement shelf 1E that recognizes the user in the shelf receives information from the infrared communication unit 26, and the movement detection unit 23 of the manual movement racks 1A, 1B, and 1C causes the manual movement shelf 1E. In addition, it is recognized that the manual movement shelves 1A, 1B, 1C located on the left side which is the detection side by the pyroelectric sensor 20 are moving. Then, the LED lamp 19 of the manual type movable shelf 1E that can be recognized by the in-shelf user is blinked in red, and the sound informing unit 22 is operated to notify the in-shelf user by sound.

  Thus, both the shelf moving user and the in-shelf user are informed that each of the manual moving shelves 1A, 1B, 1C is moving so that the manual moving shelf 1E moves in the direction of narrowing the passage 33. Therefore, it is possible to prevent the occurrence of a problem that a user in a shelf is sandwiched between shelves.

  FIG. 9 shows a fourth embodiment of the present invention. A passage 36 is formed between the manual moving shelves 1A and 1B, and a user in the shelf can enter the passage 36. Clearances 37 and 38 are formed between the manual moving shelves 1B-1C and 1C-1D, and the manual moving shelves 1D to 1F are connected in series. In the fourth embodiment, the handle lock mechanisms 24 of the manual movement shelves 1A and 1B forming the passage 36 are turned on.

  In the state shown in FIG. 9, that is, from the state in which a user in the shelf is present in the passage 36, the manual moving shelf 1D, 1E connected by rotating the handle 3 of the manual moving shelf 1F positioned at the right end by the moving shelf user. , 1F collectively to the left, the control units 21D, 21E, 21F recognize that the own shelf has moved to the left based on signals from the movement detection unit 23 and the lock detection unit 25. To do.

  Next, the control units 21D, 21E, and 21F receive information from the infrared communication unit 26, and recognize that the pyroelectric sensor 20 of the manual moving shelf 1A detects that there is a user in the shelf in the passage 36. To do. Further, the control units 21D, 21E, and 21F recognize that the handle lock mechanisms 24 of the manual movement shelves 1A and 1B are turned on. As for control part 21D, 21E, 21F, the manual type movement shelf 1D located in the edge part of the shelf which is moving as a group and the manual movement shelf 1F which the shelf movement user operates is moving. Recognize. However, the movement of the manual movement rack 1A, 1B is locked, and the pyroelectric sensor 20 detects the in-shelf user in the manual movement rack 1A and is located on the right side of the manual movement rack 1A. Since the movement of 1B is locked, the control unit 21F does not notify the movement of each of the manual movement racks 1C to 1F located on the right side of the manual movement rack 1B. This is because there is no possibility that the manual movement shelf 1B moves even if each manual movement shelf 1C-1F moves. Thereby, unnecessary notification at the time of shelf movement locking can be omitted, and usability can be improved.

  In the first to fourth embodiments described above, a notification is made when there are users in the shelves in the passages 27, 30, 33, and 36. However, in actual operation, there are cases where a user who has entered the passage once exits the passage and then does not enter the passage or enters the passage again. Therefore, the operation of the moving shelf device when the user enters the passage will be described based on the flowchart shown in FIG. 10 as the fifth embodiment including the above-described operation.

  First, it is determined whether or not the shelf is locked (ST01). Here, the self shelf refers to a shelf which is not locked by the shelf moving user and is a central shelf in the moving shelf device 18, for example, the manual moving shelf 1C shown in FIG. If it is determined that the shelf is locked, the movement of the shelf (1D, 1E, 1F in FIG. 5) next to the side where the own shelf detects pyroelectricity, that is, the right side of the shelf in this embodiment is detected In addition, it is determined whether or not a user in the shelf is detected by the pyroelectric sensor 20 (ST02). If the movement of the shelf located on the right side is not detected or if it is determined that there is no user in the shelf, the process ends, and the movement of the shelf located on the right side is detected and it is determined that there is a user in the shelf. Then, the LED lamp 19 is blinked and the voice notification unit 22 is operated to notify the user in the shelf of the shelf movement (ST03), and the process returns to step ST01.

  If it is determined in step ST01 that it is not in the locked state, it is next determined whether or not the movement of the own shelf is detected and whether the left or right shelf is moving (ST04). If the movement of the own shelf is not detected, or if the shelf on either the left or right side is moving, then some shelf movement is detected and the own shelf is used in the shelf by the pyroelectric sensor 20 It is determined whether a person is detected (ST05). If some shelf movement is detected and it is determined that there is a user in the shelf, the process proceeds to step ST03 and then returns to step ST01. If no shelf movement is detected or if it is determined that there is no user in the shelf, the process is terminated.

  If it is determined in step ST04 that the movement of the own shelf is detected and the movement of either the left or right shelf is not detected, the user in the shelf is detected by the pyroelectric sensor 20 in any of the next shelves. It is determined whether or not (ST06). When the user in the shelf is detected, the process proceeds to step ST03 and then returns to step ST01. If a user in the shelf is not detected, it is determined whether or not a certain time has elapsed after detection of pyroelectricity (ST07). If the certain time has elapsed, the process is terminated. If the predetermined time has not elapsed, the control unit 21 blinks the LED lamp 19 on the right shelf in yellow, notifies the shelf moving user of attention (ST08), and then returns to step ST01. .

  According to the above-described configuration, even if the user in the shelf who has entered the passage enters the passage again within a predetermined time, the shelf moving user can be alerted by the pyroelectric sensor 20. Even when the detection is interrupted, it is possible to prevent the occurrence of a problem such as a person being caught in the passage, and to further improve safety.

  FIG. 11 shows a block diagram of the control unit 4 used in the sixth embodiment of the present invention. The control unit 4 is connected to the LED lamp 19, the pyroelectric sensor 20, the voice notification unit 22, the movement detection unit 23, the lock detection unit 25, and the infrared communication unit 26, and each exchanges signals. Like the control unit 21, the control unit 4 includes a system control unit 4a, an own shelf status update unit 4b, another shelf status update unit 4c, and a notification status update unit 4d.

  In the sixth embodiment, each manual movement shelf 1 is provided with a sensor that is a movement direction detection unit 5 that detects the movement direction thereof. A signal from the movement direction detection unit 5 is input to the control unit 4, so that the control unit 4 moves in the direction in which the manual movement shelf 1 is moving in the direction of widening the passage or in the direction of narrowing down the passage. It is possible to judge whether or not. The operation of the sixth embodiment will be described based on the flowchart shown in FIG.

  First, it is determined whether or not the shelf is locked (ST11). Here, the self shelf refers to a shelf which is not locked by the shelf moving user and is a central shelf in the moving shelf device 18, for example, the manual moving shelf 1C shown in FIG. If it is determined that it is in the locked state, the side on which the own shelf detects pyroelectricity next, that is, the shelf located on the right side of the own shelf in this embodiment (1D, 1E, 1F in FIG. 5) is the direction of the own shelf. It is determined whether or not the user's shelf is detected by the pyroelectric sensor 20 (ST12). If the movement of the shelf located on the right side in the direction of its own shelf is not detected or if it is determined that there is no user in the shelf, the process is terminated, and the movement of the shelf on the right side in the direction of its own shelf is detected. When it is determined that there is a user in the shelf, the LED lamp 19 is blinked and the voice notification unit 22 is operated to notify the user in the shelf of the shelf movement (ST13), and the process returns to step ST11.

  If it is determined in step ST11 that it is not in the locked state, it is next determined whether or not the movement of the own shelf is detected and whether the left or right shelf is moving (ST14). If the movement of the own shelf is not detected or if either the left or right shelf is moving, it is detected that the next shelf moves in the direction of the own shelf, and the own shelf is in focus. It is determined whether or not the in-shelf user is detected by the electric sensor 20 (ST15). If it is detected that some shelf moves in the direction of the shelf and it is determined that there is a user in the shelf, the process proceeds to step ST13 and then returns to step ST11. If it is not detected that some shelf moves in the direction of the shelf, or if it is determined that there is no user in the shelf, the process is terminated.

  If it is determined in step ST14 that the movement of the own shelf is detected and the movement of any one of the left and right shelves is not detected, the user in the shelf is detected by the pyroelectric sensor 20 in any of the next shelves. It is determined whether or not (ST16). When the user in the shelf is detected, it is determined whether or not the own shelf is moving in the direction of the shelf where pyroelectricity is detected (ST17), and if it is moving, the process proceeds to step ST13. After that, the process returns to step ST11, and the process is terminated if it has not moved. When the user in the shelf is not detected, it is determined whether the user in the shelf is detected by the pyroelectric sensor 20 in any shelf (ST18), and the user in the shelf is not detected. If so, the process ends.

  If a user in the shelf is detected in some shelf in step ST18, it is determined whether or not a certain time has elapsed after pyroelectric detection (ST19). If the certain time has elapsed, the process is performed. finish. If the fixed time has not elapsed, it is determined whether or not the shelf is moving in the direction of narrowing the passage (ST20). If the shelf is not moving in the direction of narrowing the passage, the process is terminated. When moving in the direction of narrowing the passage, the control unit 4 notifies the shelf moving user to be alerted by blinking the LED lamp 19 on the right shelf in yellow (ST21), and then step ST11. Return to.

  According to the above-described configuration, the same operational effects as in the fifth embodiment can be obtained, and there is no notification when the shelf moves in the direction of expanding the passage, and the mobile shelf user and the shelf are not notified. Usability can be improved by suppressing unnecessary notifications to the inside user.

  In each of the above embodiments, the pyroelectric sensor 20 is used as the in-passage detection means. However, instead of the pyroelectric sensor 20, an area sensor capable of detecting an object may be used as the in-passage detection means. What exists in the passage in this case includes obstacles that obstruct the movement of the shelf in addition to the users in the shelf. In each embodiment, a manual moving shelf is shown as a moving shelf constituting the moving shelf device 18, but an electric moving shelf can be used instead of the manual moving shelf. In the case of using an electric movable shelf, the movement detection unit 23 and the lock detection unit 25 are established by receiving information from the operation control board of the movement shelf. Further, in each of the above embodiments, the LED lamp 19 is arranged at the center of the handle 3. However, the arrangement position of the LED lamp 19 is not limited to this, and any place such as any place on the front panel can be easily understood by the user. It may be provided anywhere.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to such specific embodiments, and unless specifically limited by the above description, the present invention described in the claims is not limited. Various modifications and changes are possible within the scope of the gist. The effects described in the embodiments of the present invention are merely examples of the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
