Description

  The present invention relates to a picking system that takes out a predetermined number of articles from a predetermined display shelf or stores them in a predetermined shelf based on an instruction from an upper management device.

While receiving the picking cart with the data receiving means and the display means in the warehouse where a large number of article displays are arranged, the data receiving means receives the instruction data transmitted from the upper management device and displays it on the display means. A picking system for picking an article based on the displayed instruction data is already known from Patent Document 1 and the like. In such a picking system, there is a case where picking is instructed based on the number of units of a box in which a plurality of the articles are packed to form one box and the number of loose articles in order to facilitate work. For example, if the number of picking instructions is 18 in the case of 10 articles per case, the cart display unit is instructed by a display including 1 case and 8 roses.
JP 2000-44021 A

  However, in the above example, it is better to take two articles from one case than to take eight loose articles, but the instruction is always in the number of case units as described above. Since the display adds the number of articles, workability may be poor depending on the number of instructions and the number of articles per case.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a picking system capable of giving a picking instruction that does not deteriorate workability depending on the number of instructions for picking and the number of articles per case. .

Further, although not shown, a scanner is provided for reading a barcode of an article to be picked.

  FIG. 2 is a block diagram showing a system configuration example of the picking system according to the present invention. Each of the picking carts 10-1, 10-2,... 10-n can communicate with the management apparatus 100 via the wireless router 101. The wireless router 101 is an access point having a router function, and can be simultaneously connected to the wireless LAN 102 and a wired LAN (not shown).

  FIG. 3 is a block diagram showing a system configuration of the picking cart 10. The picking cart 10 includes a CPU 20, a RAM 21, a ROM 22, a first display unit 16, a second display unit 17, a charging power supply unit 23, a communication unit 24, a first weighing unit (base scale 13) 25, and a second weighing unit (base scale 14). 26, a third weighing unit (table scale 11) 27, a fourth weighing unit (table scale 12) 28, a scanner 30, a printer 18, and a speaker unit 31. The CPU 20 executes various calculations and controls each part of the picking cart 10. The RAM stores data read by the CPU 20, flags and registers used when the CPU 20 performs processing, instruction data for picking transmitted from the management apparatus 100, and the like. The ROM 22 stores a program for operating the CPU.

  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.

  A container No. mounted on each weighing unit (base scale) of the picking cart 10 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 when the picking work is performed with the same picking cart 10. It transmits to each picking cart 10.

  FIG. 4 shows an example of instruction data for instructing the biking received by the picking cart 10. As shown in the figure, the instruction data includes “location number”, “product name”, “JAN code (barcode information)”, “total number of instructions”, “number of pieces”, “unit weight (g)”, “ There are “case tare weight”, “reference number”, “delivery destination information”, and “container position”. Here, “unit weight (g)” is a unit weight of an article to be picked, and “reference number” is a reference value of whether to use a subtraction display form or an addition display form. For example, “−3” If there are, up to −3, that is, if the number of roses can be expressed by −1 and −2, it means that the subtraction display is made, and if it is −4 or more, the addition display is made. The “container position” is the position of the platform scale (metering unit) on which the container of the picking cart 10 is mounted. Here, the upper stage balance 13 (first weighing section 25) is “A”, the stage balance 14 (second weighing section 26) is “B”, and the lower stage balance 11 (third weighing section 27) is “C”. 12 (fourth measuring unit 28) is set to “D”. “Location No.” is assigned by position information indicating the position where the article is arranged so that the position of each shelf and the article in the shelf can be specified according to a certain rule in the warehouse. Since each worker is familiar with the location information, the destination can be understood by looking at the location information displayed on the display units 16 and 17. Further, since the location information is printed and pasted on a label or the like so that the location information is visible, each shelf can be moved to the designated shelf by looking at the label.

  One article (product) is identified for each location, and each is in the form of JAN code, total number of instructions, number of articles stored in case, unit weight of article, case unit weight, subtraction or addition display form The reference number of containers and the container mounting position information (A, B, C, D) are set. Here, for example, a light weight article is stored in the containers in the upper A and B positions, and a heavy object is stored in the lower C and D positions.

  FIG. 5 is a diagram showing an operation flow of the picking work. First, before the picking operation is started, the first display unit 16 of the picking cart 10 displays “person number”, “person name”, “password”, “switch key”, “ten-key” as shown in FIG. "Is displayed. First, in step ST1, when the person in charge of picking inputs the person-in-charge number, the input of the person-in-charge number is accepted, and the location where location information is displayed on the first display unit 16 as shown in FIG. An initial screen on which no information is displayed is displayed in the information area, the instruction data area where instruction data is displayed, and the container information area indicating each container. Subsequently, in step ST2, the displayed “start” key is pressed.

  When the “start” key is pressed, the CPU 20 requests instruction data from the management apparatus 100 via the communication unit, and the CPU 20 receives instruction data for picking from the management apparatus 100 via the communication unit 24. The instruction data is stored in a predetermined area of the RAM 21. In step ST3, four labels for each container number of the instruction data are issued from the printer 18. 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. In each pasted label, the store name and branch of the delivery destination are printed based on the delivery destination information set for each container No. of the picking instruction data, and each container No. is barcoded and printed. Has been.

  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.

  When confirmation of the correspondence between all the 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, “Sh-A-201 shown in FIG. "Is 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.

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. In other words, the corresponding location No. “A-201” is stored in the location information area, the total number of instructions 35, the instruction data, 12 variations-1, case 3 in the instruction data area, and the corresponding container in the container information area. The number of roses and the number of cases are displayed as instruction data. Here, the CPU 20 determines whether to perform subtraction display or addition display based on the total instruction number data, entry number data, and reference number data of the instruction data stored in the RAM 21 in step ST7, and indicates in the determined display form. Data is displayed. The shampoo ABC located in the container No. “110” and the location No. “A-201” has an instruction number “35”, an entry number “12”, and the reference number is “−3”. A display of “three” and “−1” roses is displayed on both the first display unit 16 and the second display unit 17.
Hereinafter, a specific method for calculating the instruction data calculated by the CPU 20 will be described. In this case, the number of instructions is “35”, the number of entries is “12”, and the reference number is “−3”.
1. Divide the number of instructions by the number of entries. In this case, the quotient “2” and the remainder “11” are calculated.
Enter “3” obtained by adding 1 to the quotient calculated in 2.1 and multiply the number by “12”. In this case, “36” is calculated.
3. The number “36” calculated in 2 above is subtracted from the indicated number “35”. In this case, “−1” is calculated.
4). Since “−1” calculated in step 3 is larger than the reference number “−3” as a number, the CPU 20 determines that the subtraction display mode is adopted. That is, “3” obtained by increasing the quotient by 1 in 2 is the number of cases, and “−1” calculated in 3 is the number of roses.
In addition, in the case of the addition display form, “2” calculated in 1 above is the number of cases, and “11” is the number of roses.

  That is, it means an instruction to take out one article from three cases and one case in between. When the same instruction number “35” is displayed as instruction data, it is possible to display the case “2” and the rose “11”, but it is possible to display 11 rose articles from one case rather than removing them from the shelf. Picking out one article improves picking work. In addition, when the number of cases increases, the cases can be used as they are in the delivery destination, so that the work efficiency is improved.

  Next, in step ST8, the operator puts the instructed two cases and the three cases in which one article is taken out from one case into the container at the A position.

  Next, in step ST9, the CPU 20 uses the weight data output from the first weighing unit (the platform scale 13) 25 on which the container at the position A is placed, and is equivalent to three case tare weights stored in the RAM 21. The weight is subtracted, and it is determined whether the value is equal to the value obtained by multiplying the indicated number by the unit weight (determining whether the weight is correct). 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.

  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, the total picking instruction number “35”, the case “3”, and the information “−1” are transmitted, and the result file of the management apparatus 100 is updated. FIG. 11 is a diagram showing an example of the actual result file. The JAN code “4512345891075” of the location number “Sh A-201”, the “stock quantity” indicating the total number of roses of the product name “Shampoo ABC”, and the stock quantity of the case “Number of stock cases” indicating “The number of roses” indicating “Number of rose articles” arranged on the shelf is updated. Thereby, the management apparatus 100 can grasp the total number of articles actually arranged on the shelf, the number of cases, and the number of roses.

  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.

  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, and an instruction is given to move the picking cart 10 to a predetermined position and to lower the container at the predetermined position. The In step ST13, if the weight does not match, an error indicating that the number is not present is displayed, and a display indicating that the correct number is to be input is displayed on both the first display unit 16 and the second display unit 17. .

  In the above embodiment, the CPU 20 of the picking cart 10 determines whether the display is addition display or subtraction display. However, the management apparatus 100 determines whether the display is addition display or subtraction display, and determines the required number of cases. The number of roses may be transmitted to the picking cart 10 as instruction data. And when determining whether to use the addition display form or the subtraction display form, since the number of cases is one more than the addition display when making the subtraction display, the calculated number of cases is the inventory case in the actual result file. You may make it judge whether it is made to display by subtraction, judging whether it is sufficient compared with a number.

Further, by touching a portion for displaying the number of entries in the first display portion 16 and the second display portion 17, for example, a portion where “12” in FIG. 10 is displayed, an addition display is performed from the subtraction display form in the above example. An operation means for switching the display form to the form may be provided. In this case, the CPU 20 performs an operation of dividing the total number of instructions 35 by the number of entering 12, and the quotient is 2 and the remainder is 11, so that 2 cases and 11 are displayed. Thus, for example, when the number of cases actually displayed is insufficient, the instruction data to be simplified can be confirmed by changing from the subtraction display to the addition display. In addition, a dedicated key for switching may be provided on each of the first display unit 16 and the second display unit 17.
The switching example will be described using the example described in paragraph [0029]. In the case of the subtraction display form as in the above example, the instruction number is received and stored as “35”. Divide the number by the number entered. In this case, the quotient is “2”, the remainder is “11”, the number of cases is “2”, the number of roses is “11”, and the display is switched to the addition display form.
When switching from the addition display form to the subtraction display form, the CPU 20 executes the following processing. In this case, since the number of instructions “35”, the number of entries “12”, and the reference number “−3” are received and stored in the same manner as in the above example, the following steps are taken.
1. Divide the number of instructions by the number of entries. In this case, the quotient “2” and the remainder “11” are calculated.
Enter “3” obtained by adding 1 to the quotient calculated in 2.1 and multiply the number by “12”. In this case, “36” is calculated.
3. The number “36” calculated in 2 above is subtracted from the indicated number “35”. In this case, “−1” is calculated.
4). Since “−1” calculated in 3 above is larger than the reference number “−3” as a number, the CPU 20 determines that the subtraction display form is adopted, and “3” obtained by increasing the quotient by 2 in 2 above is the number of cases. Then, “−1” calculated in the above 3 is set as the rose number, and the display mode is switched to the subtraction display mode.
When switching to the subtraction display mode, the number calculated in 2 is subtracted from the indicated number “35” in 3 above, but if the value is smaller than the reference number, the subtraction display mode is not displayed. You may do it. That is, control may be performed so that subtraction display is not performed for numbers smaller than the reference number.

  In addition, the total number of instructions for rose articles is displayed. Normally, the total number of roses is not displayed, but if there are not enough cases displayed on the shelf, etc. A key operation unit for displaying instruction data consisting of the total number of roses may be provided. Further, the reference data may not be the number, but may be a ratio of, for example, half (including) the number included in one case. In the above example, the negative reference number “−3” is used. However, for example, “9” may be used as the reference number with respect to the number “12”. That is, up to nine may be added and displayed. That is, if the reference number is positive, addition display is allowed up to that number, and if it is negative display, subtraction display is allowed up to that number. Further, the reference number that is the reference information may be set by the management apparatus 100 so as to be different for each article, or the same reference number may be adopted uniformly for all articles. .

  In the above example, in step ST4, the instruction data is displayed by reading the barcode of the article to be picked at the location. However, the present invention is not limited to this, and the work at one location is finished. The next location and the instruction data to be picked at the location may be displayed.

  In the above-described embodiment, an example in which control is performed by one CPU 20 has been described. For example, a CPU that controls communication with a host and a display of the first display unit 16 including an antenna, a second display unit 17 and a printer. The picking cart 10 may be controlled by the CPU, the CPU 30 that controls the scanner 30, the first to fourth weighing units 25 to 28, and the two CPUs. Further, the key for declaring the completion of the work is the completion key in the first display unit 16 and the second display unit 17, but the key itself may be provided in the picking cart 10.

  In the above embodiment, the example in which the instruction data is displayed on the first display unit 16 and the second display unit 17 of the picking cart that moves in the warehouse has been described. However, the instruction data is displayed on the display unit of the cart. The case is not limited. In the picking cart display section, the location number of the article to be picked is shown. Are displayed, and the worker moves to the indicated shelf position. The shelf may be provided with a display unit corresponding to the article, and the instruction data may be displayed on the display unit. Moreover, you may utilize this invention with the cart which is not equipped with the display part. That is, the location number of the article to be picked before the work starts. It is also possible to receive the list with the mark on paper, and the worker moves to this position, and in the same way as described above, a display unit is provided at a position corresponding to the article, and the instruction data is displayed on the display unit. In this case, the completion of work can be transmitted to the management apparatus by providing a switch for declaring work completion on the display unit. Further, the appearance of the picking cart in the above example is not limited, the number of display units may be one, and the number of containers is not limited to four.
