Further, the tag reader 60 has an information reading range (information communication range) that reads information from the shelf-side tag 65 and the container-side tag 66 in a non-contact manner. Specifically, the communication range formed radially from the antenna 62 can be set within a predetermined range. The information reading range of the tag reader 60 is set in accordance with the readable area of the shelf-side label 65 described later. During the classification operation, the information reading range does not change and remains within a certain range.

(Shelf-side label 65)

As shown in FIG. 5, the shelf-side label 65 stores information related to the classification operation of the articles 2 such as the position information of each compartment 16 (position information of the mobile shelf 15), and is provided in each compartment of the mobile shelf 15. 16 front side upper part. Since the shelf-side tag 65 is read by the tag reader 60, it is possible to detect whether or not the worker H has picked the designated article 2 from the storage box 12 placed on the designated compartment 16. The shelf-side label 65 is supported on the mobile rack 15 by a support member (not shown) that is detachable from the mobile rack 15. The support member supporting the shelf-side label 65 includes a fixing member (not shown) formed by, for example, a magnet and fixing the shelf-side label 65 to the mobile rack 15, and a shelf-side label formed of, for example, a sponge or the like. A buffer member (not shown) buffering between 65 and the fixing member. Since the shelf-side label 65 is detachably supported on the mobile rack 15 by the support member, it can be freely attached to any position of the mobile rack 15. Specifically, for example, when the insertion position of the arm of the worker H is shifted to the right with respect to the compartment 16, the mounting position of the shelf-side label 65 is changed to the upper right side of the compartment 16. In addition, for example, when a picking worker H who performs a picking operation in a picking area P downstream of the picking area P on which the shelf-side label 65 is provided, selects the mounting position of the shelf-side label 65 when the picking operation is performed across the picking area P Transformed into the upper part on the downstream side of the compartment 16.

In addition, the shelf-side tag 65 has a readable area (communication range) in which the tag reader 60 can read information in the shelf-side tag 65 in a non-contact manner. The readable area of the shelf-side label 65 can be adjusted according to the size (installation area) of the shelf-side label 65. Specifically, the readable area is enlarged by increasing the size of the shelf-side label 65, and the area is narrowed by reducing it. The readable area of the shelf-side label 65 can be set on the mobile shelf 15. The positional relationship of a plurality of other rack-side labels 65 placed is adjusted. As described above, since the shelf-side labels 65 are provided on each of the compartments 16, when the distance between the shelf-side labels 65 provided on the adjacent compartments 16 is short, there may be mutually readable areas. Interference occurs. Therefore, the size and installation position of the shelf-side label 65 are adjusted so that the readable area of the shelf-side label 65 and the readable area of the shelf-side label 65 provided in the adjacent compartment 16 do not interfere. In addition, the direction of the readable area of the shelf-side label 65 can be directed toward the worker H who performs the sorting operation on the mobile rack 15 on which the shelf-side label 65 is provided, and performs the sorting operation further downstream. Personnel H make adjustments. As described above, when the worker H who performs the picking operation in the picking area P on the downstream side of the picking area P on which the shelf-side label 65 is installed, picks the shelf-side label 65 in a readable manner across the picking area P The direction of the area is adjusted towards the downstream side of the compartment 16.

(Container-side label 66)

As shown in FIG. 6, the container-side tag 66 stores information related to the sorting operation of the articles 2 such as the position information of the container 10 and is provided on the front side of the display main body 30 that is put into the display 26. When the container-side label 66 is read by the tag reader 60, it is possible to detect whether or not the worker H has put the designated article 2 into the designated container 10. That is, the container-side tag 66 is a storage unit for input detection that detects whether or not the article 2 is dropped into the container 10. In addition, the container-side tag 66 includes a readable area (communication range) where the tag reader 60 can read information in the container-side tag 66 in a non-contact manner. The readable area of the container-side label 66 can be adjusted according to the size (installation area) of the container-side label 66. As described above, the readable area of the shelf-side label 65 is adjusted so that the readable area of the shelf-side label 65 provided on the adjacent compartment 16 does not interfere, which is greater than the readable area of the container-side label 66. narrow. In addition, label reading The information reading range of the device 60 is set according to the readable area of the shelf-side label 65. During the classification operation, the information reading range does not change and remains at a certain range. Therefore, the readable area of the container-side label 66 and the readable area of the shelf-side label 65 provided on the mobile shelf 15 are adjusted accordingly so that they can be read by the label reader 60 set as described above. Specifically, by increasing the size of the container-side label 66, the readable area is enlarged to such an extent that it does not interfere with the readable area of another adjacent container-side label 66.

(Container Position Label 67)

As shown in Fig. 6, the container position label 67 stores instructions assigned to the user. Information related to the sorting operation of the article 2 such as a number is provided on the side surface of the container 10. Since the container position tag 67 is read by the detection reader 58, it is possible to detect the container 10 that has moved to its own drop zone Z. That is, the container position tag 67 is a storage unit for position detection that detects the position of the container 10. In the picking device 1, the container position label 67 is provided on the container 10, but it is not limited to this. For example, it may be provided on the input display 26. In this case, the detection reader 58 is installed on the display 26 side (the display moving line C side).

(Preparation before picking)

Next, preparations before the picking operation will be described. As described above, the worker H performs a picking operation in each picking area P while wearing the tag reader 60. Therefore, it is necessary to associate the tag reader 60 carried by the worker H with the picking area P where the worker H performs a picking operation. Therefore, in the picking device 1, before the picking operation is started, it is necessary to associate the tag reader 60 carried by the worker H with the data receiver 57 provided in the picking area P where the worker H performs the picking operation. Specifically, before the picking operation is started, the worker H reads an associated tag, such as a passive tag, through the antenna 62 of the tag reader 60 worn on the arm. Sign (not shown). The associated label is provided in each picking area P, and stores information related to the position information of the picking area P, information related to the data receiver 57 provided in the picking area P, and the like. The worker H reads the associated tag with the tag reader 60, and inserts the antenna 62 of the tag reader 60 worn on the wrist into any of the shelves 17 of the mobile rack 15, and reads any of the shelf-side tags 65. Therefore, when the display / completion button 19B of the compartment display 19 corresponding to the read shelf-side label 65 blinks (or lights up), it is considered that the tag reader 60 and the document receiver 57 are associated.

(Use in picking operations)

Next, an operation at the time of a sorting operation in the sorting device 1 will be described. The sorting device 1 can be operated in the following three modes depending on whether the tag reader 60 is used or not. First, in the first mode, the worker H performs a picking operation without using the tag reader 60. That is, the traditional method. As shown in FIG. 7, when the zone controller 55 confirms that a new container 10 has arrived by detecting the reader 58 (S1 -Yes), each display performs display and lighting (S2). Specifically, in the picking area P side, the number of articles 2 is displayed on the digital display 19A of the compartment display 19, and the display / done button 19B performs, for example, yellow lighting, and the light 20A of the interval display 20 is turned on. On the side of the putting-in zone Z, the lamp with the switch 23 and the second lamp portion 33 of the putting-in display 26 are turned on, for example, in yellow. In S2, when each display is displaying and lighting, the worker H sorts the indicated number of articles 2 from the compartment 16 (accommodating box 12) which is lit by the display / completion button 19B of the compartment display 19, and selects The good article 2 is put into the container 10 which is lit by the second lamp portion 33 of the display 26 (S3). In S3, when the sorting of the article 2 is completed, the worker H presses the display / completion button 19B of the compartment display 19 (S4). As a result, the zone controller 55 determines that the picking operation for the instructed compartment 16 (accommodating box 12) is completed, and the display / completion button 19B of the compartment display 19 is turned off. At this time, the digital display of the zone controller 55 on the compartment display 19 In a state where the number of items 2 remaining in the device 19A is displayed, the compartment display 19 is controlled.

On the other hand, in S3, when all the articles 2 which should be put in the container 10 are put in, the finish button 28 of the auxiliary display 27 provided on the switch 23 with completion of blinking blinks (S5). Due to the blinking of the completion button 28, the worker H presses the completion completion belt switch 23 or the completion button 28 (S6). As a result, the zone controller 55 determines that all the articles 2 that should be put into the container 10 are put in, and turns off each display (S7). Specifically, on the side of the picking area P, the number of articles 2 in the digital display 19A of the compartment display 19 is turned off. On the side of the input zone Z, the auxiliary display 27 (completion button 28) provided on the switch 23 with completion of the input is turned off. Although the second lamp portion 33 of the input display 26 is turned on in another color (for example, yellow is normally turned on and is white), it is turned off when the container 10 is moved to the downstream loading area Z. In this way, in the first mode, the zone controller 55 uses the information (signal) of the display / completion button 19B of the compartment display 19 and the completion button 28 with the switch 23 or the auxiliary display 27 to determine whether the picking operation and the input operation are Completion judgment (an example of a unit completion judgment function of the display control unit).

Next, the second mode will be described. The second mode is a mode in which the worker H performs a picking operation in combination with the tag reader 60, the display / completion button 19B of the compartment display 19, the completion completion switch 28 with the switch 23, and the accessory display 27. As shown in FIG. 8, when the zone controller 55 confirms that a new container 10 has arrived by detecting the reader 58 (S11 -Yes), each display performs display and lighting (S12). Specifically, it is the same as S2. In S12, when each display is displaying and lighting, the worker H picks up the indicated number of articles 2 from the display 16 (accommodation box 12) of the display / completion button 19B of the partition display 19, and picks up The good article 2 is put into the container 10 which is lit by the second lamp portion 33 of the display 26. (S13). Next, in S13, while the worker H is picking the article 2, the tag reader 60 reads information from the shelf-side tag 65 provided in the designated compartment 16 (S14), and passes the read information through the data The receiver 57 sends it to the zone controller 55 (S15). According to S15, if the zone controller 55 receives the information (signal) from the tag reader 60, the zone controller 55 does not pass the integrated controller 51 to the "operator H in the instructed compartment 16 (accommodation box 12), It is determined whether or not the designated article 2 and quantity are to be picked (S16). In S16, if the zone controller 55 determines that "the worker H has not selected the designated item 2 or quantity in the designated compartment 16 (accommodation box 12)" (S16-No), the zone controller 55 makes The display / completion 19B button of the compartment display 19 blinks at a predetermined time in another color (for example, it is normally white when the yellow light is turned on) (S17). At this time, the zone controller 55 controls the compartment display 19, and even if the worker H presses the display / completion button 19B, the display / completion button 19B does not turn off the light. The worker H visually recognizes the blinking of the display / completion button 19B, and restarts the picking of the article 2 (S13). On the other hand, in S16, the zone controller 55 determines that "the worker H has picked the designated article 2 and quantity in the designated compartment 16 (accommodating box 12)" (S16-Yes), then the zone The controller 55 blinks the display / completion button 19B of the compartment display 19 (S18). Thereby, the zone controller 55 can control the compartment display 19 so that the worker H can press the display / completion button 19B and the display / completion button 19B can turn off the light. When the display / completion button 19B flashes in S18, the worker H presses the display / completion button 19B (S19). As a result, the zone controller 55 determines that the picking operation for the instructed compartment 16 (accommodating box 12) is completed, and turns off the display / completion button 19B. At this time, the zone controller 55 controls the compartment display 19 in a state where the number of articles 2 remaining in the digital display 19A of the compartment display 19 is displayed.

On the other hand, in S13, the worker H puts the picked item 2 into At the same time as the container 10 is collected, the tag reader 60 reads information from the container-side tag 66 provided for the indicated container 10 (S20), and sends the read information to the area controller through the data receiver 57 55 (S21). According to S21, if the zone controller 55 receives information (signal) from the tag reader 60, the zone controller 55 does not pass the integrated controller 51 and instructs "the operator H to input the instructed container 10 into the container Of items 2 and quantity "(S22). In S22, when the zone controller 55 determines that "the worker H has not put the designated article 2 and quantity into the designated container 10" (S22-No), the zone controller 55 turns on the first LED 24A. (When the sorting is performed in advance, the second LED lamp 24B is turned on) (S23). At this time, the zone controller 55 controls the switch-on completion belt switch 23, and even if the operator H presses the switch-on completion belt switch 23, the lamp on the switch-off completion belt 23 will not turn off. The worker H visually turns on the first LED lamp 24A, and restarts the input of the article 2 (S13). On the other hand, in S22, when the zone controller 55 determines that "the worker H has put the designated article 2 and quantity into the designated container 10" (S22-Yes), the zone controller 55 causes the The finish button 28 of the accessory display 27 provided on the finish belt switch 23 blinks (S24). As a result, the zone controller 55 controls the completion-of-input belt switch 23 and the auxiliary display 27 (completion button 28) so that the worker H can press the completion-of-input belt switch 23 or completion button 28, and the completion button 28 of the auxiliary display 27 can turn off the light. According to S24, when the completion button 28 of the auxiliary display 27 blinks, the worker H presses the completion completion belt switch 23 or the completion button 28 (S25). As a result, the zone controller 55 determines that the input of the article 2 of the designated container 10 is completed, and turns off the completion button 28 of the auxiliary display 27. The other displays are also turned off in the same manner as in the first mode. In this way, in the second mode, the zone controller 55 is based on the information (signal) sent from the tag reader 60, the display / completion button 19B from the compartment display 19, and the completion button of the switch 23 and the accessory display 27 that have been turned on. The 28 information (signal) judges whether the picking operation and the putting operation are completed.

Next, a third mode will be described. The third mode is a mode in which the worker H performs a picking operation using only the tag reader 60. Hereinafter, in the third mode, from S31 to S37 and from S40 to S43 are the same as those in the second mode from S11 to S17 and from S20 to S23, so descriptions thereof are omitted. As shown in FIG. 9, in S36, the zone controller 55 determines that “the worker H has picked the designated article 2 and the quantity in the designated compartment 16 (storage box 12)” (S36-Yes). The zone controller 55 determines that the picking operation for the indicated compartment 16 (accommodating box 12) is completed, and turns off the display / completion button 19B of the compartment display 19 (S38). At this time, the zone controller 55 controls the compartment display 19 in a state where the number of articles 2 remaining in the digital display 19A of the compartment display 19 is displayed. On the other hand, in S42, when the area controller 55 determines that "the worker H has put the designated article 2 and quantity into the designated container 10" (S42-YES), the area controller 55 determines that the After the designated collection container 10 has finished putting in the item 2, the auxiliary display 27 (completion button 28) provided on the switch 23 with completion of completion is turned off (S44). In addition, similar to the first mode, the other displays are also turned off.

In this way, in the third mode, the zone controller 55 determines whether the picking operation and the putting operation are completed based on the information (signal) sent from the tag reader 60 (an example of the automatic completion judgment function of the display control unit). In addition, the zone controller 55 can be performed in units of each compartment 16 (compartment display 19) of each shelf 17 or in each input zone Z (input completion zone switch 23, auxiliary display 27 (completion button 28)). Switching from the first to third modes.
