A work instruction file to be stored is stored.

  FIG. 5 is a diagram showing a planar layout of a warehouse that performs a picking operation using the picking system according to the present invention. As shown in the drawing, a plurality of article (product) display shelves 51 are arranged in the warehouse 50 at a predetermined interval. Each shelf is given a “location number” 53 for each shelf. “Location No.” 53 is allocated by the position information indicating the position where the article is arranged so that the position of each article display shelf 51 and the article in the article display shelf 51 can be specified in the warehouse 50 according to a certain rule. Is. Since each worker is familiar with the location information, the destination can be understood by looking at the location information displayed on the first display unit 16 and the second display unit 17 of the picking cart 10. In addition, each item display shelf 51 is printed and affixed on a label or the like so that the location information can be visually recognized, so that the user can see the label and move to the designated shelf. For example, the location No. displayed on the route B from the start point 52 in FIG. The picking operation is performed at the position 53 and moved to the delivery area 54.

  FIG. 6 is a diagram illustrating an example of a work instruction file. The work instruction file is created based on order data transmitted from the host computer 200. One line and one line of the work instruction file are information for instructing the work. For one work, “container No.”, “shipment quantity (picking quantity)”, “location number”, “product code”. "Delivery destination code", "shipping time (work end time)", "worker number (code)", etc. are set. The work for which no shipping time is set here is the last working time of the day (for example, 20:00 hours) and the shipping time (work end time). The work instruction file is stored in the hard disk (HDD) 41 as described above.

  The container No. Is a container number in which an article (product) picked by the work instruction is stored. The shipment quantity (picking quantity) is the number of articles (products) to be picked, the location number. Is information specifying the location of the article (product) on the article display shelf 51 of the warehouse 50, and the product code is information specifying the product (article). The delivery destination code is information for specifying the delivery destination. In addition, for example, the delivery time code is set as a key when there is a request from the delivery destination to ship by 10:00. Further, when the shipping time is not set, it means that the work is completed by the work end time of the day (for example, 20:00) as described above. In the case of picking work instruction data for which the shipping time is set, the CPU 40 of the management apparatus 100 performs control so that the picking work instruction data for which no shipping time is set is prioritized and transmitted to the picking cart 10. To do.

  One line of the work instruction file indicates the work. Here, as shown in FIG. 1, since the picking cart 10 equipped with the four containers 32 is used, picking work instruction data for the four containers 32 (FIG. 6). D1, D2,... Of the picking work instruction information transmitted from the management apparatus 100 to the picking cart 10 in response to a single instruction request signal transmitted from the picking cart 10. However, here, one container No. In this example, only one article (product) is picked, but this is not a limitation. A work instruction for picking a plurality of articles may be used. In addition, which four container Nos. Whether to combine the picking work instruction data is determined by calculation processing by the CPU 40 of the management apparatus 100 so that the moving distance of the picking cart 10 is shortened as much as possible in consideration of the location where the article is located. That is, here, when the management apparatus 100 receives an instruction request signal from the picking cart 10, any four sets of picking work instruction data are transmitted to the picking cart 10 in time for the requested worker's work time. Controls what to do.

  The worker number (code) is the worker code of the picking cart 10 that has transmitted the picking work instruction data from the management device 100. Before starting the work with the picking cart 10, as shown in FIG. 7, the “worker number” and the “worker name” are entered on the display surface of the first display unit 16 of the picking cart 10. The data is stored in a predetermined area of the RAM 21. Since the instruction request signal transmitted from the picking cart 10 is transmitted together with the “worker number” and “worker name”, the worker who transmitted the instruction request signal is specified in the transmitted picking work instruction data. The operator code to be stored can be stored in four sets of instruction data instructing the work.

  In addition, since four containers 32 are mounted on one picking cart 10, four types of container numbers. The picking work instruction data is transmitted to the corresponding picking cart 10. That is, for example, the location No. BH200 to S5405 (see D1 in FIG. 6) is one work instruction, and picking an article at four locations means that the one work instruction is completed. However, here, four types of container numbers. Since the four containers 32 are mounted on the picking cart 10, only four types are used. Even if four containers are mounted, three or two container Nos. The instruction data corresponding to the above may be used as a single work instruction. As described above, one container No. The work instruction may consist of picking work instruction data for moving a plurality of locations and picking a plurality of articles (goods).

  As shown in FIG. 1, the first display unit 16 is provided in front of (in front of) the handle 15 and is configured as a liquid crystal touch panel. The second display unit 17 is provided on the side surface of the picking cart 10 and is configured as a liquid crystal touch panel in the same manner as the first display unit 16. The charging power supply unit 23 supplies power to each device mounted on the charged picking cart 10. As shown in FIG. 2, the communication unit 24 communicates with the upper management apparatus 100 via the wireless LAN 102. The scanner 30 is provided for reading a barcode attached to an article. The first weighing unit 25 to the fourth weighing unit 28 are mounted with containers for storing the picked items such as the folding type as described above. Further, the printer 18 prints and issues a label to be attached to each container and a picked result. The speaker unit 31 is provided to notify an error by sound.

  The container No. mounted on each weighing unit 25 to 28 (table scales 11 to 14) of the picking cart 10 is displayed. Indicates one delivery destination. Based on a large amount of order data received from a large number of stores or the like, the upper management device 100 generates instruction data that can be efficiently picked with a short moving distance when picking with the same picking cart 10. It transmits to each picking cart 10.

  FIG. 8 is a diagram showing an operation flow of picking work. First, before the picking work is started, the first display unit 16 of the picking cart 10 has screens of “worker number”, “worker name”, “switch key”, and “ten-key” as shown in FIG. It is displayed. First, in step ST1, when the worker of the picking work inputs the worker number, the input of the worker number is accepted, and an initial screen is displayed on the first display unit 16 as shown in FIG. This initial screen displays a location information area where location information is displayed, an instruction data area where instruction data is displayed, and a container information area indicating each container. No information is displayed in each area. Absent. Subsequently, in step ST2, the “start” key on the displayed touch panel is pressed.

  When the “start” key is pressed, the CPU 20 of the picking cart 10 requests instruction data from the management device 100 via the communication unit, and the CPU 20 picks the picking device for picking from the management device 100 via the communication unit 24. The work instruction data is received, and the picking work instruction data is stored in a predetermined area of the RAM 21. In step ST3, the instruction data container No. Four labels are issued from the printer 18 for each label. Each label corresponds to each container, and the mounting positions A, B, C, and D are printed at the corners of the four labels to be issued. Since the upper row of the picking cart 10 is predetermined as A and B, and the lower row is determined as C and D, the worker (person in charge) puts the issued label on the side surface of the container at the mounting positions A, B, C, and D. paste. Each pasted label is printed with the store name and branch of the delivery destination based on the delivery destination information set for each container No. of the picking instruction data. Etc. are barcoded and printed.

  Barcodes indicating A, B, C, and D are attached to the locations of the containers of the picking cart 10. In step ST4, the barcode of the label attached to the container in step ST3 and the barcode printed on the label attached to the A position of the picking cart 10 are read by the scanner 30, and the position of the container is not wrong. Is confirmed. In the same manner as described above, the barcode printed on the label attached to the B, C, D position of the picking cart 10 and the label attached to the side surface of the container mounted at the B, C, D position are printed. The scanned barcode is read by the scanner 30, and it is confirmed whether the container position is correct. Here, the time from when the start key in step ST2 is pressed until the last correspondence of the containers A, B, C, and D in step ST4 is measured as the pre-preparation ability.

  When confirmation of the correspondence of all containers A, B, C, and D is completed in step ST4, in step ST5, the first article of the instruction data received in step ST3, for example, “BH-200” shown in FIG. And the like are displayed on both the first display unit 16 and the second display unit 17. Subsequently, in step ST6, the worker moves the picking cart 10 to the location displayed on the display unit, and reads the barcode attached to the article located at the location by the scanner 30. The time until the JAN code from step ST5 to step ST6 is read is measured as the time for calculating the walking ability. And since the place which starts the picking cart 10 in the warehouse 50 is predetermined as shown in the start point 52 of FIG. 5, the distance from this start point 52 to the said location No. 53 is calculated. Then, the walking speed is calculated by dividing the calculated distance by the time measured as the walking ability, and this becomes the walking ability. Since the location position in the warehouse 50 is determined in advance as coordinates, the distance can be calculated based on the coordinates.

  Next, in step ST7, when the JAN code of the instruction data received in step ST2 matches the JAN code read from the barcode attached to the article, the display as shown in FIG. And the second display unit 17. That is, the corresponding location number “BH200” is displayed in the location information area, and “shipment quantity: 1” is displayed in the instruction data area. Container No. Is displayed on both the first display section 16 and the second display section 17 with the product name “AAAA” located in the location number “BH200”. In step ST8, the operator takes out the instructed product (article) and puts it into the container at the A position.

  Next, in step ST9, the CPU 20 equals the weight of the product name “AAAA” stored in the RAM 21 to the weight data output from the first weighing unit (base scale 13) 25 on which the container at position A is placed. To determine whether it is the correct weight. If the weight is correct (YES), the process proceeds to step ST10, and the instruction data displayed in the container information area is erased from both the first display unit 16 and the second display unit 17 as shown in FIG. The display prompts you to press. On the other hand, if the weight is not correct (NO) in step ST9, the process proceeds to step ST13. If the values do not match, an error indicating that there is no number is displayed, and the first display unit 16 and the first display unit 16 indicate that the correct number is to be input. 2 is displayed on both display units 17.

  The product (article) of the shipment quantity instructed in step ST7 is put into the container A, and when completed, the completion key is pressed, so that the picking instruction data from step ST7 to step ST10 is displayed and then the picking is completed. Measure the time until. Then, when the measurement time is divided by the number of picking instructions, the picking time per picking number is calculated as the picking ability.

  Next, in step ST10, when the completion key is pressed, the data worked at the corresponding location number is sent to the management apparatus 100. In this case, information on the shipment quantity: “1” is transmitted, and the result file of the management apparatus 100 is updated. Next, in step ST11, it is determined whether or not there is instruction data for the next location among the instruction data stored in the RAM 21, and if there is (YES), the process proceeds to step ST5 and the above processing is repeated. If not (NO), the process proceeds to step ST12.

  If there is a next product (article) in step ST11, the next location is displayed. As measured in steps ST5 to ST6, the location from the location No. to the next designated location is displayed. The distance is calculated, the walking ability is similarly calculated, and the walking speed of the worker number is sequentially stored. The picking ability is similarly calculated and stored sequentially. When sequentially stored, an average value including the stored data is calculated at the same time, stored at the top, and each capability information is updated. Then, when the worker number is specified and the worker ability is read out, each of the averaged ability information is read out.

  In step ST12, the fact that all work has been completed is displayed on both the first display unit 16 and the second display unit 17, the picking cart 10 is moved to a predetermined position (the delivery area 54 in FIG. 5), and the container is moved. You are instructed to drop it in place. In step ST13, when there is no weight, an error indicating that the number is not displayed is displayed, and a display indicating that the correct number is input is displayed on both the first display unit 16 and the second display unit 17. .

  In step ST12, the next location number is not displayed, and the picking instruction is displayed in the first display unit 16 and the instruction data area of the second display unit 17 and the container information area (see FIG. 9) of the picking cart 10. When the data is not displayed, a display indicating that all data is completed is displayed on the first display unit 16 and the second display unit 17, and the picking operation for one instruction is completed by pressing the completion key. When the picking work is completed, the worker moves the picking cart 10 to the delivery area 54 (see FIG. 5), and lowers the container from the picking cart 10 to shift to preparation for delivery. Then, for the next picking instruction, the worker places the container 32 on the platform of the picking cart 10 as shown in FIG. 1, moves to the start point 52 in FIG. 5, and presses the start key in step ST2. Thus, the next picking operation is instructed. Here, the time (seconds) from the work end display in step ST12 until the next start key is pressed in step ST2 is measured. This measured time becomes the clean-up ability.

  Each time the pre-preparation ability, walking ability, picking ability, and clean-up ability are calculated / calculated as described above, each value is stored in the worker file sequentially, and the average value is the highest for each worker. It memorizes in the upper line, and this becomes each ability of the person in charge. FIG. 13 is a diagram showing an example of the worker file. As shown in the figure, the worker file includes “worker number”, “preparation ability (seconds)”, “walking speed (m / second)”, “picking speed (seconds / piece)”, “post-cleaning ability ( Second) "," attendance time ", and" leaving time ". In the portion B of “Preparation Ability (sec)”, “Walking Speed (m / sec)”, “Bicking Speed (sec / piece)”, and “After-cleaning Ability (sec)”, each picking operation The calculated / calculated value is stored as history information, and the average value is stored in the portion A, that is, the top row.

  FIG. 14 is a diagram showing an example of a progress file indicating the progress status of the instructed picking work. As shown in the figure, the progress file stores the worker number and the corresponding progress status. As described in the work instruction file shown in FIG. 6, one picking work instruction includes four container numbers. Indicated by data consisting of Then, the location No. required for one picking work instruction is set. Each time the picking operation at one location is completed, the completion key displayed on the first display unit 16 and the second display unit 17 of the picking cart 10 is pressed. Each time the operation is completed, the number of molecules is counted up by one. When all of the work with one picking work instruction is completed, for example, when the number of workers with the worker number “1111” in the progress file becomes 4/4, all the work with one picking work instruction is finished. It is judged that it was done, and it is deleted from the progress file. Then, when new picking starts and picking instruction data is transmitted to the worker with worker number “1111”, an item with worker number “1111” is generated in the new progress file. As described above, the progress file is used to manage the progress of work for each worker, and is updated each time work at one location is completed.

  The operation flow of the picking work shown in FIG. 8 is a basic operation flow. However, in the present invention, in order to complete the picking work by a predetermined time, the worker who has transmitted an instruction request signal from the management apparatus 100 is used. The picking work instruction data is presented in consideration of the work end time (shipping time), the ability of the worker, the worker's leaving time, and the progress of other workers. In addition, a plurality of picking work instruction data is divided and presented so that the work is finished by the work finish time (shipping time) set by the worker. This will be described in detail below.

[Presentation according to work end time (shipping time)]
FIG. 15 is a diagram showing a processing flow of the CPU 40 of the picking work management apparatus 100 according to the present invention. Here, processing in the case of presenting picking work instruction data in accordance with work end time (shipping time) is shown. In step ST21, when there is an urgent picking work instruction, the operation unit 44 of the management apparatus 100 inputs the work end time (shipping time) to each picking work instruction data in the work instruction file (see FIG. 6). For example, when an urgent delivery instruction is issued after specifying a product from a certain delivery destination, a delivery destination code is set in advance in each picking work instruction data, so the delivery destination code of the delivery destination is designated. Thus, urgent picking work instruction data can be specified. Thereby, when there is an instruction request from the picking cart 10, the picking work instruction data is transmitted to the picking cart 10 as instruction data from the work for which the shipping time is set.

  The management device 100 receives an instruction request signal together with the worker number from the picking cart 10 (step ST22). That is, when the start key is pressed on the picking cart 10, the worker number and the instruction request signal stored in the RAM 21 (see FIG. 3) of the picking cart 10 are transmitted to the management apparatus 100 via the communication unit 24. The management device 100 receives the worker number and the instruction request signal. Subsequently, the worker number is specified from the worker file (see FIG. 13) stored in the hard disk (HDD) 41 (see FIG. 4), the ability information of the worker is read, and temporarily stored in the RAM 42 (step ST23). ). That is, the preparatory ability information, walking speed information, picking speed (pieces / second) information, and post-cleaning ability information of the worker file are read and temporarily stored in the RAM 42. Subsequently, from the work instruction file stored in the hard disk (HDD) 41, from the picking work instruction data closest to the current time among the work for which the work end time is set, first the target picking work instruction data Is extracted (step ST24). In this case, for example, picking work instruction data for which a shipping time of 10:00 is set is extracted.

  It is determined whether the work of the picking work instruction data extracted in step ST24 is in time for the work end time (step ST25). This determination is made as follows. First, the time difference between the shipping time (work end time) set in the picking work instruction data of the work instruction file stored in the hard disk (HDD) 41 and the current time read from the clock unit 46 is calculated. Then, the distance for walking between the locations of all the extracted picking work instruction data is calculated, and the distance required for walking is calculated by dividing the distance by the walking speed information of the worker ability information read in step ST23. . Then, the above-mentioned step ST23 is read out, and the time required for the preparations stored in the RAM 42, the time required for rear clearing, and the calculated time for walking are calculated.

  Then, the time difference between the work end time and the current time read from the clock unit 46 is compared with the total total time to determine whether the work end is in time for the end time (shipping time) (step ST25). ) If YES, the picking work instruction data is sent to the picking cart 10 that sent the instruction request signal in step ST22. If NO, the process returns to step ST24 to extract the picking work instruction data as a target again. Perform (step ST24). In the re-extraction of the picking work instruction data, the picking work whose work end time (shipping time) is closer to the current time, for example, 11:00 is the shipping time, except for the picking work instruction data extracted last time. Extract instruction data. The same operation as described above is repeated for the extracted picking operation instruction data.

[Presentation according to the worker's leave time]
FIG. 16 is a diagram showing a processing flow of the CPU 40 of the management apparatus 100 of the picking system according to the present invention. Here, a process in the case of presenting picking work instruction data in accordance with the worker's leaving time is shown. Unlike the case of the process shown in FIG. 15, the shipment time (work end time) is not set in the picking work instruction data of the work instruction file, and it is determined whether or not it matches the leaving time of the worker who performs the picking work. 3 shows a processing flow in the case of sending picking work instruction data to the picking cart 10 that has sent the instruction request signal. First, the management apparatus 100 receives an instruction request signal together with the worker number from the picking cart 10 (step ST31). Next, the corresponding worker number is identified from the worker file (see FIG. 13) stored in the hard disk (HDD) 41, the ability information of the corresponding worker is read, and the RAM 42 of the management apparatus 100 (see FIG. 4). (Step ST32). That is, pre-preparation ability information, walking speed information, picking speed (pieces / second) information, post-cleaning ability information, and work time are read out and stored in the RAM 42.

  Next, target picking work instruction data is extracted from the work instruction file (step ST33). In this case, it is assumed that the shipping time (work end time) is not set, and the upper four instruction data in the work instruction file, that is, “container No.”, “shipment quantity”, “location No.”, “product” "Code" is extracted sequentially. It is determined whether the picking work instruction data extracted in step ST33 is in time for the worker's leaving time (step ST34). (NO in step ST35), if NO, return to step ST33 and repeat the process.

  In step ST34, it is determined whether the time for leaving work is in time as follows. First, a time difference between the work time temporarily stored in the RAM 42 in step ST32 and the current time read from the clock unit 46 is calculated. And the distance which the operation | work of the picking work instruction | indication data extracted walks between all the locations is calculated, This distance is divided by the walking speed read by step ST32, and the time concerning walking is calculated. Next, all the picking numbers of each picking work instruction data extracted are added to calculate the total number. Then, the picking speed stored in step ST32 is multiplied by the total number to calculate the total picking time. Then, the pre-preparation and post-cleaning time stored in the RAM 42 in step ST32, the calculated walking time, and the total picking time are all added up, and the total time is calculated. Then, the time difference between the leaving time and the current time read from the clock unit 46 is compared with the total time to determine whether the time is enough. In addition, since the above is a problem that is close to the work time, the current time when the management apparatus 100 receives the instruction request signal from the picking cart 10 is compared with the preset work time of each individual person. If it is longer than a predetermined time (for example, 1 hour), the determination in step ST34 may not be performed.

[Presentation considering the progress of other workers]
FIG. 17 is a diagram showing a processing flow of the CPU 40 of the management apparatus 100 of the picking system according to the present invention. Here, a processing flow in the case of presenting picking work instruction data in consideration of the progress status of other workers is shown. First, the management apparatus 100 receives an instruction request signal together with the worker number from the picking cart 10 (step ST41). That is, when the start key is pressed on the picking cart 10, the worker number and the instruction request signal stored in the RAM 21 (see FIG. 3) of the picking cart 10 are transmitted to the management device 100, and the management device 100 performs this work. The user number and the instruction request signal are received. The CPU 40 of the management apparatus 100 identifies the corresponding worker number from the worker file (see FIG. 13) stored in the hard disk (HDD) 41, reads the capability information of the worker, and temporarily stores it in the RAM 42. (Step ST42). That is, the preparatory ability information, walking speed information, picking speed information, and post-cleaning ability information of the worker are read and temporarily stored in the RAM 42.

  Next, from the work instruction file (see FIG. 6) stored in the hard disk (HDD) 41, the shipment time closest to the current time from the picking work instruction data in which the shipping time (work end time) is set. Is extracted as target work instruction data, and a picking number of the extracted picking work instruction data is also stored in a predetermined area of the RAM 42. In this case, for example, picking work instruction data for which a shipping time of 10:00 is set is extracted (step ST43). Subsequently, it is determined whether the work of the picking work instruction data extracted in step ST44 is in time for the set shipping time (step ST44). If YES, the process proceeds to the next step ST45. Returning to the process, the picking work instruction data to be extracted is extracted again. In the extraction of the picking work instruction data again, the picking No. stored in the predetermined area of the RAM 42 extracted last time. Picking work instruction data whose shipping time (work end time) is closer to the current time, for example, picking work instruction data whose next 11:00 is the shipping time is extracted from the picking work instruction data other than the picking work instruction data. The determination in step ST44 is repeated for the work instruction data. This determination is made as follows.

  First, the time difference between the set shipping time (work end time) and the current time read from the clock unit 46 is calculated. And the distance which walks between all the locations of the extracted picking operation | work instruction data is calculated, The time which walks is calculated by dividing this distance by the walking speed information read by said step ST42. Next, all the picking numbers of the extracted picking work instruction data are added to calculate the total picking number. Then, the total picking time is calculated by multiplying the picking speed information read out in step ST42 by the total picking number. Then, the total preparation time is calculated by adding all the time required for preparation and clean-up read in step ST42, the time required for walking, and the total picking time. Then, the time difference between the shipping time and the current time read from the clock unit 46 is compared with the total total time to determine whether or not it is in time.

  In step ST45, a progress file (see FIG. 14) that is updated every time work is completed at one location of each worker is referred to. Next, workers other than the worker who has received the instruction request signal in step ST41 are identified in order from the top of the progress file. Then, the capability information of the worker is read from the worker file and temporarily stored in the RAM 42 (step ST46). For example, when the worker number 1112 is specified, each capability information of the worker having the worker number 1112 is read and temporarily stored in the RAM 42. The number of remaining locations of the worker is calculated from the progress file (step ST47). For example, since the worker number 1112 has the progress information of 3/4, it is understood that the work at one location obtained by subtracting 3 from 4 remains.

  Next, the distance calculated from the current working location and the remaining location is read out in step ST46 from the remaining location calculated in step ST47 and the worker number (code) in the work instruction file. The walking time calculated by dividing by the walking speed is multiplied by the picking speed read in step ST46 by the picking instruction number in the remaining locations, and the calculated picking time and further read in step ST46. Then, the time until the completion of the work of the picking work instruction data is calculated (step ST48). Subsequently, a work completion time is calculated when the worker identified in step ST46 performs the work of the picking work instruction data extracted in step ST43 (step ST49).

  Subsequently, the time calculated in step ST48 is added and temporarily stored in the RAM 42 (step ST50). Further, the time calculated in step ST50 is subtracted from the total time calculated in step ST44, and the result is stored in the RAM 42. Temporarily store (step ST51). It is determined whether the processes from step ST46 to step ST51 have been executed by all workers stored in the progress file (step ST52). If YES, the process proceeds to step ST53. If NO, the process returns to step ST46. . In step ST53, it is determined whether or not the value temporarily stored in the RAM 42 in step ST51 has a positive number. If NO, the process proceeds to step ST54. If YES, the process returns to step ST43.

  In the determination of step ST53, YES, that is, there is a positive number means that the worker specified in step ST46 is faster than the worker who received the instruction request signal in step ST41. This means that the work of the extracted picking work instruction data can be processed. Further, NO, that is, a negative number, is determined that the worker who has received the instruction request signal in step ST41 can complete the work earlier than the worker specified in step ST46.

  Therefore, if NO in step ST53, that is, if there is no positive number, the process proceeds to step ST54, and the picking work instruction data extracted in step ST43 is sent to the worker who has received the instruction request signal in step ST41, that is, the instruction request. It transmits to the picking cart 10 which transmitted the signal. If YES in step ST53, that is, if there is a positive number, the other worker can perform the work of the picking work instruction data extracted in step ST43 earlier, so the process returns to step ST43 and the picking work instruction to be processed again. Re-extract the data. When the picking work instruction data is extracted again at step ST43, the picking No. stored last time and stored in the RAM 42 is extracted. The picking work instruction data whose shipping time is closer to the current time, for example, the picking work instruction data whose shipping time is the next 11:00 is extracted from the picking work instruction data other than the above, and the above step ST44 for the extracted work instructions. Repeat the process of ~ ST53.

[Split presentation]
FIG. 18 is a diagram showing a processing flow of the CPU 40 of the management apparatus 100 of the picking system according to the present invention. Here, a processing flow for dividing and processing the picking work instruction data instructed by another worker is shown. An instruction request signal is received from the picking cart 10 together with the worker number. That is, when the start key displayed on the first display unit 16 of the picking cart 10 is pressed, the worker number and the instruction request signal stored in the RAM 21 of the picking cart 10 are transmitted to the management device 100 for management. The apparatus 100 receives the worker number and the instruction request signal (step ST61).

  The CPU 40 of the management apparatus 100 identifies the corresponding worker number from the worker file (see FIG. 13) stored in the hard disk (HDD) 41, reads the capability information of the worker, and temporarily stores it in the RAM 42. (Step ST62). That is, the preparatory ability information, walking speed information, picking speed information, and post-cleaning ability information of the worker are read and temporarily stored in the RAM 42. Subsequently, in the work instruction file (see FIG. 6), picking work instruction data that is close to the current time among picking work instruction data for which the shipping time (work end time) is set is first selected as the target picking work instruction. Extracted as data (step ST63). In this case, for example, picking work instruction data in which a shipping time of 10:00 is set is extracted, and the extracted four picking numbers are stored in a predetermined area of the RAM 42. Remember.

  It is determined whether or not the extracted picking work instruction data is in time for the set shipping time (work end time) (step ST64). This determination is made as follows. First, the time difference between the shipping time and the current time read from the clock unit 46 is calculated. And the distance which walks between all the locations of the work of the extracted picking work instruction | indication data is calculated, This distance is divided by the walking speed read by step ST62, and the time concerning walking is calculated. Next, all the picking numbers of the extracted biking work instruction data are added to calculate the total picking number. Then, the picking speed read in step ST62 is multiplied by the total picking number to calculate the total picking time. Then, the total picking time is calculated from the time required for preparation and clean-up read in step ST62 and the calculated time required for walking. Then, the time difference between the shipping time and the current time read from the clock unit 46 is compared with the total total time to determine whether it is in time. If YES, the process proceeds to step ST65, and if NO, the process proceeds to step ST66.

  In step ST65, the picking work instruction data extracted in step ST63 is transmitted to the worker who has received the instruction request signal, that is, the worker who has received the instruction request signal in step ST61. In step ST66, the four picking numbers temporarily stored in step ST63 are stored. Is divided into a predetermined number of containers. For example, the container is divided into two containers (step ST66). One of the picking work instruction data divided into two divided containers is specified as work instruction data (step ST67). Subsequently, it is determined whether it is in time for the shipping time (step ST68). If YES, the process proceeds to step ST65. If NO, the other picking work instruction data divided in step ST66 is also specified (step ST69). Subsequently, it is determined whether it is in time for the shipping time (step ST70). If YES, the process proceeds to step ST65. If NO, the process returns to step ST63 and repeats the process. Note that the determinations in steps ST68 and ST70 are made in the same manner as in step ST64, but the number of locations is reduced. In addition, in step ST70, No. In the case of, picking no. However, the picking numbers other than those temporarily stored in the RAM 42 are extracted. To extract.
