[4. Operation of Picking Aid System S]
Next, the operation of the picking auxiliary system S will be described with reference to FIGS. 13 and 14. Before the process shown in the flowchart shown in FIG. 13 is started, the terminal device 3 has started an application program for picking work and is waiting for the barcode reader 4 to read the two-dimensional code 501. To do.

  First, when the control unit 31 of the terminal device 3 receives the two-dimensional code 501 read by the bar code reader 4, the control unit 31 decodes the two-dimensional code 501 and decodes the code content (that is, the instruction written in the work instruction 500. The code content corresponding to the number is acquired (step S1A) and transmitted to the server device 1 (step S2A). Note that a program for compounding the two-dimensional code 501 is installed in the terminal device 3, and the two-dimensional code 501 is compounded using the program.

  When receiving the code content from the terminal device 3 (step S1B), the control unit 11 of the server device 1 refers to the two-dimensional code table 124 and acquires the instruction number corresponding to the received code content (step S2B). . Next, the control unit 11 refers to the status field of the progress table 125 (step S3B). Specifically, the control unit 11 refers to the record in which the instruction number acquired in the process of step S2B is registered, and the status field indicates “not yet”, “working”, or “done”. Check if it is registered. At this time, the control unit 11 first determines whether or not “done” is registered in the status field (step S4B), and determines that “done” is registered (step S4B: YES). ), The process proceeds to step S1B. At this time, the control unit 11 has completed the picking work for the work instruction sheet 500 in which the two-dimensional code that is the basis of the code content transmitted in the process of step S2A is described with respect to the terminal device 3. It is good also as transmitting the information which shows that, and displaying the message which shows that on the display part 34. FIG. On the other hand, when it is determined that “done” is not registered in the state field (step S4B: NO), the control unit 11 determines whether “working” is registered in the state field (step S4B). S5B).

  When the control unit 11 of the server apparatus 1 determines that “working” is registered in the status field (step S5B: YES), the control unit 11 sends warning information to the sequencer 7 so that the warning lamp P is lit. Output (step S18B), and the process shown in the flowchart ends. Note that the sequencer 7 to which the warning information is input outputs a signal for turning on the warning lamp P to the warning lamp P. On the other hand, when determining that “working” is not registered in the status field (step S5B: NO), the control unit 11 changes the status field of the progress table 125 to “working” (step S6B). . Specifically, the control unit 11 changes the status field of the record in which the instruction number acquired in step S2B is registered to “working”.

  Next, the control unit 11 of the server apparatus 1 extracts a record in which the instruction number acquired in step S2B is registered in the instruction number field from the combined list 126 (step S7B). For example, when the instruction number acquired in the process of step S2B is “000001”, seven records shown in FIG. 10 are extracted. Next, based on the record extracted in the process of step S7B, the control unit 11 displays the order display unit 91 and the quantity display unit 92 of the display board 9 installed in the frame where the document D to be picked is placed, respectively. A numerical value is displayed (step S8B). Specifically, for each extracted record, the control unit 11 stores the shelf position information registered in the shelf position field, the order information registered in the order field, and the quantity information registered in the quantity field with the sequencer 7. Send to. In response to this, the sequencer 7 displays the numerical value indicated by the order information on the order display portion 91 of the display board 9 installed at the shelf position (frame) indicated by the shelf position information, and indicates the quantity information on the quantity display portion 92. Display numerical values.

  Next, the control unit 11 of the server device 1 transmits the enclosed number information indicating the enclosed number, which is the number of documents D to be enclosed, to the terminal device 3 based on one work instruction sheet 500 (step S9B). Specifically, the control unit 11 acquires the number of records extracted in the process of step S7B as the enclosed number, and transmits the enclosed number information.

  When receiving the enclosed number information from the server device 1, the control unit 31 of the terminal device 3 records the enclosed number information in the storage unit 32 (step S3A).

  Next, when the weight is measured by the weighing scale 5, the control unit 31 of the terminal device 3 acquires the measured weight (step S4A). According to the method of using the picking auxiliary system S, when the picking order and the picking quantity are displayed on the display board 9 by the processing of step S8B, the worker W sequentially picks the document D according to the display on the display board 9. Place on the cart 2. The weight scale 5 transmits weight information indicating the measured weight to the terminal device 3 every several milliseconds. The control unit 31 determines that the document D is newly placed when the weight indicated by the received weight information changes by more than a predetermined threshold (except when the weight changes due to the vibration of the cart 2). Get the weight after. Therefore, the weight acquired by the control unit 11 here is a value obtained by summing the weights of all documents D placed on the cart 2.

  Next, when the document D placed on the cart 2 is photographed by the camera 6, the control unit 31 of the terminal device 3 acquires the photographed image (step S5A). The timing at which the camera 6 releases the shutter may be the timing at which the control unit 31 acquires the weight. For example, when the weight indicated by the weight information changes by a predetermined threshold or more, the control unit 31 may output a signal to the camera 6 so as to release the shutter. Next, the control unit 31 extracts the feature points of the image acquired in the process of step S5A (step S6A). As a method for extracting the feature points of the image, a conventionally known method can be adopted.

  Next, the control unit 31 of the terminal device 3 provides the server device 1 with collation information including weight information indicating the weight acquired in the process of step S4A and feature point information indicating the feature point extracted in the process of step S6A. Transmit (step S7A). Next, the control unit 31 adds “1” to the transmission counter provided in the storage unit 32 (step S8A). The transmission counter is cleared to zero each time a new two-dimensional code is acquired in the process of step S1A. Next, the control unit 31 determines whether or not the value of the transmission counter matches the enclosed number indicated by the enclosed number information recorded in the storage unit 32 in the process of step S3A (step S9A). The process of step S9A is a process for determining whether or not the picking of the document D to be enclosed has been completed. When it is determined that the value of the transmission counter matches the enclosed number (step S9A: YES), the control unit 31 ends the process illustrated in the flowchart. On the other hand, when it is determined that the value of the transmission counter does not match the enclosed number (step S9A: NO), the process proceeds to step S4A.

  On the other hand, when receiving the verification information from the terminal device 3 (step S10B), the control unit 11 of the server device 1 adds “1” to the reception counter provided in the storage unit 12. Note that the reception counter is cleared to zero at any time from the process of step S6B to the process of step S9B.

  Next, the control unit 11 of the server device 1 collates the combination list 126 with the collation information received in the process of step S10B (step S12B). Specifically, the control unit 11 acquires the value of the reception counter (the picked order of the document D from which the collation information has been acquired in the processing of the latest step S10B), and the value of the order field is the value of the reception counter. Is compared with the value indicated by the weight information included in the verification information. Further, the control unit 11 includes feature point information included in the collation setting file specified by the collation setting file number registered in the collation setting file number field in the record in which the value of the order field matches the value of the reception counter; The feature point information included in the verification information is compared.

  Next, the control part 11 of the server apparatus 1 determines whether the result of collation is OK (step S13B). The control unit 11 determines that the weight and the accumulated weight match (determine that they are within a predetermined allowable range), and the comparison results of the feature point information match (if they are within the predetermined allowable range, determine that they match) ) Is determined to be OK. At this time, if the control unit 11 determines that the collation result is not OK (step S13B: NO), the control unit 11 outputs warning information to the sequencer 7 so as to turn on the warning lamp P (step S18B). The process shown in the flowchart is terminated. On the other hand, when it is determined that the result of the collation is OK (step S13B: YES), the control unit 11 then determines whether or not the value of the reception counter matches the enclosed number obtained in the process of step S9B. Is determined (step S14B).

  When the control unit 11 of the server device 1 determines that the value of the reception counter does not match the enclosed number (the document D to be picked remains) (step S14B: NO), the display on the display board 9 is displayed. Update (step S15B). Specifically, the control unit 11 displays the display board installed at the shelf position (frame) indicated by the shelf position information registered in the shelf position field in the record compared with the verification information in the process of the latest step S12B. 9 is turned off. As a result, as the operator W picks the correct document D in the correct order, the number of the display boards 9 on which the order and the quantity are displayed decreases. On the other hand, when it is determined that the value of the reception counter matches the enclosed number (the document D to be picked does not remain) (step S14B: YES), the control unit 11 sets the status field of the progress table 125 to “ It is changed to “Done” (step S16B). Specifically, the control unit 11 changes the status field of the record in which the instruction number acquired in the process of step S2B is registered to “done”.

  Next, the control unit 11 of the server device 1 turns off the display of the display board 9 that has been displaying the order and quantity until then (step S17B), and ends the processing shown in the flowchart.

  As described above, in the picking assist system S (an example of “information processing system”) according to the present embodiment, the operator W selects some types from among a plurality of types of documents D (an example of “object”). Is an information processing system that assists a series of picking operations for picking each document D in a predetermined order, and the storage unit 12 (an example of “object information storage means”) A combination in which order information indicating the order to be picked in the picking operation is associated with weight information (an example of “specific information”) and feature point information (an example of “specific information”) for specifying the document D of the type. Records (an example of “object information”) in the list 126 are stored, and the control unit 11 (an example of “specific information acquisition unit”, “order acquisition unit”, “comparison unit”, “output control unit”) W Weight information (an example of “specific information”) and feature point information (an example of “specific information”) are acquired (step S10B), and weight information and feature points in a series of picking operations are identified. The picked order of the document D from which the information has been acquired is acquired with reference to the reception counter (steps S11B and S12B), the order acquired in the processing of steps S11B and S12B with reference to the combined list 126 of the storage unit 12 And the order in which the records associated with the weight information and feature point information acquired in step S10B are compared with the weight information and feature point information, respectively, and it is determined that no record is stored. (Step S13B: NO), the warning lamp P (an example of “output means”) is turned on to output warning information (Step S18B).

  Therefore, according to the picking assist system S of the present embodiment, warning information is output when a predetermined type of document D is not picked in a predetermined order, so that the document D is picked in an incorrect order. It is possible to prevent the wrong document D from being picked. When the warning light P is turned on, the work manager collects all the picked documents D, and the worker W reads the two-dimensional code 501 of the work instruction sheet 500 again with the barcode reader 4. Let's start.

  Further, in the picking assist system S of the present embodiment, the display board 9 (an example of “display device”) is provided in each place (frame of the shelf 8) where the document D is arranged for each type. A numerical value indicating the order of picking the document D placed in the frame provided with is displayed.

  Therefore, according to the picking assist system S of the present embodiment, since the order in which the documents D should be picked is displayed on the display board 9 provided for each type of the documents D, the operator W follows the displayed order. Picking the document D can prevent the document D from being picked in the wrong order.

  Furthermore, in the picking assist system S of the present embodiment, the control unit 11 (an example of “work determination unit”, “start information acquisition unit”, “output control unit”) indicates a work instruction sheet indicating a series of picking operations. For each (ie, instruction number), it is determined whether or not the series of picking operations is in progress (step S5B), and the code contents (“start information indicating that a series of picking operations are to be started”) For example). Then, when the control unit 11 determines that one series of picking operations is being performed, and obtains the code contents related to another series of picking operations (step S1B, step S5B: YES), a warning is given. The lamp P (an example of “output means”) is turned on to output warning information (step S18B).

  Therefore, according to the picking assist system S of the present embodiment, it is possible to prevent another series of picking operations from being started during one series of picking operations, so that the document D unrelated to the series of picking operations can be obtained. The possibility of being picked can be reduced.

[5. Modified example]
Next, a modification of the above embodiment will be described. Note that the modifications described below can be combined as appropriate.

[5.1. Feature point comparison process]
In the above embodiment, the control unit 11 of the server device 1 compares the feature point information included in the verification information with the feature point information of the verification setting file. It is good also as a structure which performs a process. In this case, all the collation setting files that may be used for collation are transmitted from the server device 1 to the terminal device 3 in advance. And it is good also as a structure which transmits the comparison result and weight of feature point information by the control part 31 of the terminal device 3 to the server apparatus 1. FIG. In this case, the control unit 11 of the server device 1 executes the process of step S18B when the comparison result of the feature points is “mismatch”. If the comparison result of the feature points is “match”, only the weight information is collated in the process of step S12B.

[5.2. Weight comparison]
In the above-described embodiment, each time the document D is picked by the worker W, it is placed on the cart 2, so that the weight scale 5 is configured to measure the accumulated weight thereof. Therefore, the control unit 11 of the server device 1 compares the accumulated weight measured by the weighing scale 5 with the value of the accumulated weight field of the work list table 122 (join list 126) in the process of step S12B. It has become. As a modified example, every time the document D is picked and placed on the cart 2, the control unit 11 of the server device 1 acquires a difference value between the measurement values obtained by the weighing scale 5, and the difference value and the work list table The weight field value of 122 (binding list 126) may be compared.
