Further, the information reading range of the tag reader 60 is set in accordance with the readable area of the shelf-side tag 65 to be described later, and the information reading range does not change during the sorting operation, and is kept within a certain range.

(shelf side label 65)

As shown in FIG. 5, the shelf side label 65 stores information relating to the sorting operation of the articles 2 such as the position information of each compartment 16 (position information of the mobile rack 15), and is installed in each compartment of the flow rack 15. The upper part of the front side of 16. Since the shelf side label 65 is read by the label reader 60, it is possible to detect whether the worker H has picked up the instructed item 2 from the storage box 12 placed on the instructed compartment 16. Further, the shelf side label 65 is supported by the flow rack 15 by a detachable support member (not shown) with respect to the flow rack 15. The support member that supports the shelf-side label 65 includes a fixing member (not shown) formed of, for example, a magnet or the like, which fixes the shelf-side label 65 to the flowable shelf 15, and a label on the shelf side formed of, for example, a sponge or the like. A cushioning member (not shown) that buffers between the fixing member 65 and the fixing member. Since the shelf-side label 65 is detachably supported by the flow-through shelf 15 by the support member, it can be arbitrarily attached to any position of the flow-through shelf 15. Specifically, for example, when the arm insertion position of the worker H is biased to the right with respect to the compartment 16, the attachment position of the shelf-side label 65 is converted into the upper right portion of the compartment 16. Further, for example, in the case where the picking 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 provided is sorted by the self-picking area P, the mounting position of the shelf-side label 65 is made. It is converted into the upper portion of the downstream side of the compartment 16.

Further, the shelf side label 65 has a readable area (communicable 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 (set area) of the shelf side label 65. Specifically, the size of the shelf-side label 65 is enlarged to increase the readable area, and the area is narrowed by reduction. In addition, the readable area of the shelf side label 65 can be set according to the mobile shelf 15 The positional relationship of the plurality of other shelf side labels 65 is adjusted. As described above, since the shelf side label 65 is disposed on each of the compartments 16, when the distance between the shelf side labels 65 provided on the adjacent compartments 16 is relatively close, there is a mutual readable area. The situation of interference. Then, the size and the installation position of the shelf side label 65 are adjusted so that the readable area of the shelf side label 65 does not interfere with the readable area of the shelf side label 65 provided in the adjacent compartment 16. Further, the direction of the readable area of the shelf-side label 65 can be directed to the worker H who performs the sorting operation compared to the mobile rack 15 on which the shelf-side label 65 is provided, and the job of performing the sorting operation further downstream. Personnel H makes adjustments. As described above, in the case where 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 provided is sorted across the picking area P, the shelf-side label 65 can be read. The direction of the area is adjusted toward the downstream side of the compartment 16.

(container side label 66)

As shown in FIG. 6, the container side label 66 stores information relating to the sorting operation of the article 2 such as the position information of the stack container 10, and is provided on the front side of the display main body 30 of the display 26 to be mounted. The container side label 66 is read by the label reader 60, and it is possible to detect whether or not the worker H has placed the instructed item 2 into the instructed collection container 10. That is, the container side label 66 is a storage unit for detecting whether or not the article 2 is thrown into the collection container 10. In addition, the container side label 66 has a readable area (communicable range) in which the label reader 60 can read information in the container side label 66 in a non-contact manner. The readable area of the container side label 66 can be adjusted according to the size (set area) of the container side label 66. As described above, the readable area of the shelf side label 65 is adjusted such that the readable area of the shelf side label 65 disposed on the adjacent compartment 16 does not interfere, which is comparable to 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. In the sorting operation, the information reading range does not change and remains within a certain range. Therefore, the readable area of the container side label 66 is adjusted correspondingly to the readable area of the shelf side label 65 provided on the flow rack 15, so as to be readable by the label reader 60 set as described above. Specifically, by enlarging 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 the adjacent other container side label 66.

(container location label 67)

As shown in Figure 6, the container location label 67 stores instructions associated with the user. The information related to the sorting operation of the article 2 such as the number is set on the side of the collection container 10. Since the container position label 67 is read by the detection reader 58, it is possible to detect the collection container 10 that has moved to its own input area Z. That is, the container position label 67 is a storage unit for detecting the position of the collection container 10 . Further, in the sorting apparatus 1, although the container position label 67 is provided on the stack container 10, the present invention is not limited thereto, and for example, it may be provided on the input display 26. In this case, the detection reader 58 is provided on the side of the input display 26 (on the side of the display moving line C).

(prepare before picking work)

Next, explain the preparation before the picking operation. As described above, the worker H performs the picking operation in each of the picking areas P while wearing the tag reader 60. Therefore, it is necessary to associate the tag reader 60 carried by the worker H with the worker H in the picking work picking area P. Then, in the sorting apparatus 1, before starting the picking operation, the label reader 60 carried by the worker H needs to be associated with the material receiver 57 provided in the picking area P in which the worker H performs the picking operation. Specifically, before the start of the picking operation, the worker H reads an associated mark composed of, for example, a passive tag through the antenna 62 of the tag reader 60 worn on the arm. Sign (not shown). The associated tag is disposed in each of the picking areas P, and stores information related to the location information of the picking area P, the data receiver 57 set in the picking area P, and the like. The worker H reads the associated tag through 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 flow shelf 15, and reads an arbitrary shelf side tag 65. Thus, when the display/completion button 19B of the compartment display 19 corresponding to the read shelf side label 65 blinks (or lights), the tag reader 60 is considered to be associated with the material receiver 57.

(use during picking operation)

Then, the operation at the sorting operation in the sorting apparatus 1 will be described. The sorting device 1 can be used in the following three modes depending on whether or not the tag reader 60 is used. First, the first mode is that the worker H does not use the tag reader 60 to perform the picking operation. That is, the traditional method. As shown in Fig. 7, when the zone controller 55 confirms that a new container container 10 has arrived (S1-Yes) by the detecting reader 58, each display is displayed and lighted (S2). Specifically, in the picking area P side, the number of articles 2 is displayed in the digital display 19A of the compartment display 19, and the display/completion button 19B performs, for example, yellow lighting, and the lamp 20A of the interval display 20 is lit. In the input zone Z side, the lamp with the switch 23 and the second lamp unit 33 that has been placed on the display 26 are turned on, for example, in yellow. In S2, when each display is displayed and lit, the worker H picks up the indicated number of items 2 from the compartment 16 (accommodating case 12) that is lit by the display/completion button 19B of the compartment display 19, and will pick The good article 2 is put into the collection container 10 (S3) that is turned on by the second lamp unit 33 of the display 26. In S3, when the picking of the article 2 is completed, the worker H presses the display/complete button 19B of the compartment display 19 (S4). Thereby, the zone controller 55 judges that the picking operation for the instructed compartment 16 (accommodating case 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 in the compartment display 19 The compartment display 19 is controlled in a state where the number of articles 2 remaining in the device 19A is displayed.

On the other hand, in S3, when all the articles 2 to be placed in the collection container 10 are loaded, the completion button 28 of the accessory display 27 provided on the switch 23 is turned on (S5). Due to the flicker of the completion button 28, the worker H presses the input completion switch 23 or the completion button 28 (S6). Thereby, the zone controller 55 judges that all the articles 2 to be put into the collection container 10 are put in, and turns off the respective displays (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. In the input zone Z side, the auxiliary display 27 (the finish button 28) provided on the switch 23 is turned off. The second lamp unit 33 that has been placed in the display 26 is turned on in other colors (for example, white when the yellow lamp is normally turned on), but turns off when the container container 10 moves to the input area Z on the downstream side. Thus, in the first mode, the zone controller 55 passes the display/completion button 19B of the compartment display 19 and the information (signal) of the completion button 28 of the auxiliary display 27 or the auxiliary display 27, whether or not the picking operation and the input operation are performed. The judgment is completed (an example of the 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 the picking operation by using the tag reader 60, the display/complete button 19B of the compartment display 19, and the completion button 28 of the input switch 23 and the accessory display 27. As shown in Fig. 8, when the zone controller 55 confirms that a new container container 10 has arrived by the detecting reader 58 (S11-Yes), each display is displayed and lighted (S12). Specifically, it is the same as the above S2. In S12, when each display is displayed and lit, the worker H picks up the indicated number of items 2 from the compartment 16 (accommodating box 12) that is lit by the display/completion button 19B of the compartment display 19, and will pick the item 2 The good article 2 is put into the collection container 10 that is turned on by the second lamp unit 33 of the display 26 (S13). Next, in S13, while the worker H picks up the article 2, the tag reader 60 reads the information from the shelf side tag 65 provided in the instructed compartment 16 (S14), and passes the read information through the document. The receiver 57 transmits 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 through the master controller 51, and "the worker H is in the indicated compartment 16 (accommodating case 12), It is judged whether or not the selected item 2 and the quantity are selected (S16). In S16, the zone controller 55 judges that "the worker H does not pick the instructed article 2 or the number in the instructed compartment 16 (accommodating case 12)" (S16-No), the zone controller 55 makes The display/finish 19B button of the compartment display 19 blinks at a predetermined time in other colors (for example, white when the yellow light is normally turned on) (S17). At this time, the zone controller 55 controls the compartment display 19, and the display/complete button 19B does not turn off the light even if the worker H presses the display/completion button 19B. The worker H visually blinks the display/completion button 19B, thereby restarting the picking of the article 2 (S13). On the other hand, in S16, the zone controller 55 judges that "the worker H has selected the instructed article 2 and the number in the instructed compartment 16 (accommodating case 12)" (S16-Yes), 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 presses the display/completion button 19B to turn off the display/complete button 19B. When the display/completion button 19B is blinking in S18, the worker H presses the display/completion button 19B (S19). Thereby, the zone controller 55 determines that the sorting operation for the instructed compartment 16 (accommodating case 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 label 66 provided for the indicated collection container 10 (S20), and transmits the read information to the zone controller through the material receiver 57. 55 (S21). According to S21, if the zone controller 55 receives the information (signal) from the tag reader 60, the zone controller 55 does not pass through the master controller 51, and is instructed to "whether the worker H has invested in the indicated container container 10. The item 2 and the quantity are judged (S22). In S22, when the zone controller 55 determines that "the worker H has not input the instructed article 2 and the number to the instructed container 10" (S22-No), the zone controller 55 turns on the first LED lamp 24A. (When the picking is performed in advance, the second LED lamp 24B is turned on) (S23). At this time, the zone controller 55 controls the completion of the switch 23, and even if the operator H presses the input switch 23, the lamp with the switch 23 is turned off. The worker H visually recognizes the lighting of 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 placed the instructed article 2 and the quantity for the instructed container 10" (S22-Yes), the zone controller 55 makes the input. The completion button 28 of the accessory display 27 provided on the switch 23 is blinked (S24). Thereby, the zone controller 55 controls the input of the switch 23 and the accessory display 27 (the completion button 28) so that the operator H presses the input switch 23 or the finish button 28, and the completion button 28 of the accessory display 27 can turn off the light. According to S24, when the completion button 28 of the accessory display 27 blinks, the worker H presses the input completion switch 23 or the completion button 28 (S25). Thereby, the zone controller 55 determines that the completion button 28 of the attached display unit 27 is turned off when the input of the article 2 of the instructed container 10 is completed. Further, in the same manner as in the first mode, the other displays are also turned off. Thus, in the second mode, the zone controller 55 is based on the information (signal) transmitted from the tag reader 60, the display/completion button 19B from the compartment display 19, the completion button of the input completion switch 23, and the accessory display 27. The information (signal) of 28 judges whether the picking operation and the input work are completed.

Next, the third mode will be described. The third mode is a mode in which the worker H performs the picking operation using only the tag reader 60. Hereinafter, in the third mode, since S31 to S37 and S40 to S43 are the same as S11 to S17 and S20 to S23 of the second mode, the description thereof will be omitted. As shown in FIG. 9, in S36, the zone controller 55 determines that "the worker H has selected the instructed article 2 and the number in the instructed compartment 16 (accommodating case 12)" (S36-Yes) The area controller 55 determines that the display/finish button 19B of the compartment display 19 is turned off (S38) when the picking operation of the instructed compartment 16 (accommodating case 12) is completed. 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 zone controller 55 determines that "the worker H has input the instructed article 2 and the quantity to the instructed container 10" (S42-Y), the zone controller 55 determines that it is right. When the instructed container 10 is loaded with the article 2, the auxiliary display 27 (the completion button 28) provided on the switch 23 is turned off (S44). Further, in the same manner as in the first mode, the other displays are also turned off.

As described above, in the third mode, the area controller 55 determines whether or not the picking operation and the input job are completed by the information (signal) transmitted from the tag reader 60 (an example of the automatic completion determining function of the display control unit). Further, the zone controller 55 can be performed in units of the respective compartments 16 (the compartment display 19) of each of the shelves 17, or in units of the input zones Z (the completed switch 23 and the attached display 27 (the completion button 28)). Switching from the first to third modes.

[Embodiment 2]

Next, a sorting apparatus of an example of the sorting apparatus according to the present invention will be described.

(temporary placement of the side label 68)

At the same time, a temporary placement stage side label 68 (an example of a storage unit) composed of a passive tag is provided on the upper portion of each temporary placement table 72. The temporary placement table side label 68 stores information relating to the classification operation (temporary placement operation) of the articles 2 such as the position information of each temporary placement table 72 (position information of the temporary placement shelf 71), and is placed on the temporary placement shelf 71. The upper portion is along the label support member 74 that is extended by the roller drive conveyor 21. Due to the temporary placement of the side label The 68 is read by the tag reader 60, and the worker H can detect whether or not the article 2 is temporarily placed on the instructed temporary placement table 72. Further, the temporary placement table side label 68 is supported by the label support member 74 by a support member (not shown) that is detachable from the label support member 74. Further, the temporary placement stage side label 68 has a readable area (communicable range) in which the label reader 60 can read information in the temporary placement stage side label 68 in a non-contact manner, the readable area and the flowable shelf 15 The readable area of the shelf side label 65 provided above is adjusted accordingly.

Further, the input display 26 is attached to the collection container 10 by the jig 40, and the input display 26 displays the collection container 10 to which the article 2 to be taken out from the compartment 16 of the sorting area P (see FIG. 3) is loaded. The clamp 40 is formed as a side surface In the shape of a word, a part of it is hung on the side of the collection container 10. Further, on the side of the input display 26, a container side label 66 is provided, and on the side of the temporary placement shelf 71 of the roller drive conveyor 21. The side portion is provided with a detection reader 58 that detects that the collection container 10 has moved to the input area Z for each input area Z. The detection reader 58 is disposed at the upstream end of each input area Z, in the collection container 10 When moving to the own input zone Z, the container position label 67 provided on the stack container 10 is read. Further, on the jig 23A which is disposed along the roller drive conveyor 21 and vertically set to the height of the stack container 10, The switch 23 and the auxiliary display 27 (the completion button 28) (not shown) are completed, and the LED lamps 24A‧24B are provided on the side surface of the jig 23A.

Next, the control configuration of the sorting device 70 will be described. As the control unit of the picking device 70, like the picking device 1, there is provided an integrated controller 51, a communication controller 52, and a zone controller 55 provided in each of the picking areas P.

(Zone Controller 55)

The zone controller 55 is connected to a compartment display 19 of the self-selection zone P, a data receiver 57 that receives the data from the tag reader 60, a space display 20, and a switch 23 and an auxiliary display 27 of the self-input zone Z.

Next, the operation when the picking operation is temporarily placed in the picking device 70 will be described. In the picking device 70, as in the case of the picking operation of the picking device 1, the tag reader 60 can be used in three modes depending on whether or not the tag reader 60 is used. The first mode is a mode in which the worker H does not use the tag reader 60 to temporarily place the picking operation (an example of the manual completion determining function of the display control unit), and the second mode is the worker H and uses the tag reader 60 and the compartment display. The display/completion button 19B of 19 and the completion push switch 73B of the temporary placement display 73 perform a mode of temporarily placing the picking operation, and the third mode is a mode in which the worker H performs the temporary placement picking operation using only the tag reader 60 (display control unit An example of the automatic completion judgment function). Further, the zone controller 55 can perform the first to third modes in units of the respective compartments 16 (the compartment display 19) of each of the shelves 17 or in units of the temporary placement tables 72 (temporary placement display 73). Switching. Hereinafter, the second mode will be described. Further, since the first mode is the operation of the conventional temporary placement picking operation, the third mode is that in the second mode, the display/complete button 19B of the compartment display 19 and the completion pressing switch 73B of the temporary placement display 73 are not pressed, based on The information (signal) transmitted from the tag reader 60 automatically determines the completion of the temporary placement of the picking operation, and therefore the description thereof is omitted.

As shown in FIG. 11, when the area controller 55 determines that there is an uncollected collection data (S51-Yes), each display performs display and lighting (S52). 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/completion button 19B is lit with, for example, yellow, and the lamp 20A of the interval display 20 is lit. . In the input zone Z side, the number (total number) of temporarily placed articles 2 is displayed on the number display 73A on which the display 73 is temporarily placed, and the pressing switch 73B is turned on, for example, in yellow. In S52, when each display is displayed and lighted, the worker H picks up the instructed number of items 2 from the compartment 16 (accommodating case 12) that is turned on by the display/complete button 19B of the compartment display 19, and will select the item 2 The good article 2 is temporarily placed on the temporary placement table 72 on which the push switch 73B of the display 73 is temporarily placed to be lit (S53). Then, in S53, while the worker H picks up the article 2, the tag reader 60 reads the information from the shelf side tag 65 set in the instructed compartment 16 (S54), and reads the information. It is sent to the zone controller 55 through the data receiver 57 (S55). According to S55, when the zone controller 55 receives the information (signal) from the tag reader 60, the zone controller 55 does not pass through the master controller 51, and "is the worker H in the indicated compartment 16 (accommodating case 12) The item 2 and the quantity to be instructed are selected and judged (S56). In S56, the zone controller 55 determines that "the worker H has not selected the instructed article 2 and the number in the instructed compartment 16 (accommodating case 12)" (S56-NO), the zone controller 55 makes The display/completion button 19B of the compartment display 19 blinks at a predetermined time in other colors (for example, white when the yellow light is normally turned on) (S57). The worker H visually blinks the display/completion button 19B of the compartment display 19, thereby restarting the picking of the article 2 (S53). On the other hand, in S56, the zone controller 55 determines that "the worker H has selected the instructed article 2 and the number in the instructed compartment 16 (accommodating case 12)" (S56-Yes), the zone Controller 55 causes compartment display The display/completion button 19B of the device 19 blinks (S58). Due to the blinking of the display/completion button 19B, the worker H presses the display/completion button 19B (S59). Thereby, the zone controller 55 determines that the sorting operation for the instructed compartment 16 (accommodating case 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 S53, while the worker H temporarily places the picked item 2 on the temporary placement table 72, the tag reader 60 reads from the temporary placement table side tag 68 set with respect to the instructed temporary placement table 72. The information is taken (S60), and the read information is transmitted to the area controller 55 through the material receiver 57 (S61). According to S61, when the zone controller 55 receives the information (signal) from the tag reader 60, the zone controller 55 does not pass through the master controller 51, and temporarily sets "the item 2 and the quantity to be instructed by the worker H to be The instructed temporary placement table 72" judges (S62). In S62, when the zone controller 55 determines that "the worker H has not temporarily placed the instructed article 2 and the number to the instructed temporary placement table 72" (S62-No), the zone controller 55 causes the display to be temporarily placed.
