  An embodiment of the present invention will be described with reference to the drawings.

  1 and 2, reference numeral 1 denotes a picking system. The picking system 1 is, for example, a picking facility (collection system) for the worker X to perform picking work for various products based on order information.

  As shown in FIG. 1 and FIG. 2, the picking system 1 includes a plurality of zones (a plurality of zones (product storage units) 2) in which products (articles) picked by a worker X who is a picking operator are stored. The storage shelf is provided with a storage shelf means 3 having a horizontally long shape, which is arranged in a straight line in the longitudinal direction.

  Further, the picking system 1 includes a linear first conveying means (A) that takt-conveys a case K into which goods picked by the worker X from the frontage 2 are put in the conveying direction along the longitudinal direction of the storage shelf means 3. System) 6 and a case K which is arranged in parallel with the first conveying means 6 and into which goods picked from the frontage 2 by the operator X are put in the conveying direction along the longitudinal direction of the storage shelf means 3. Second conveying means (B system) 7 for conveying is provided. The first transport unit 6 and the second transport unit 7 have at least portions corresponding to the storage shelf unit 3 arranged in parallel to each other. The case K is a box-shaped collection container whose upper surface is opened, for example.

  Further, an elongated worker space 10 is provided between the storage shelf means 3 and the first transport means 6, and a plurality of picking goods from the front opening 2 of the storage shelf means 3 is provided in the worker space 10. Workers X are located side by side.

  The storage shelf means 3 is composed of, for example, 16 zones whose zone numbers (zone numbers) are determined as “1” to “16”. In the example of FIG. 1, for example, the zones “1” and “2”, the zones “3” and “4”, the zones “5” and “6”, and the zones “7” and “8” are adjacent to each other. One worker X is set in charge of one zone. Further, regarding the zones “9” to “16”, one worker X is set as one person in charge for one zone.

  Each zone is configured by a storage shelf 11 which is a fluidized shelf, for example. The storage shelf 11 has a plurality of front rows 2 for storing products in a plurality of rows, that is, for example, six rows and four rows (total 24), but the number of usable front doors 2 (the number of front doors) is a number of 24 or less. Can be set arbitrarily.

  As shown in FIG. 3, each zone is composed of 24 frontage 2 whose frontage addresses (addresses) are determined as “01” to “24” in order from the lower side to the upper side. Note that the same row address is a smaller number toward the left end in front view. The frontage 2 location is composed of a zone number and an address.

  Further, frontage instruction means 13 positioned corresponding to the frontage 2 are provided on the front surface of each storage shelf 11. The frontage instruction means 13 instructs the worker X of the frontage 2 in which the goods to be picked are stored. The frontage instruction means 13 is, for example, an LED lamp provided for each frontage 2. Each storage shelf 11 is provided with a zone monitor 14 as a display device. That is, a zone monitor 14 serving as notification means is provided for each zone. Note that the zone monitor 14 is not necessarily provided.

  The 1st conveyance means 6 is comprised by conveyor apparatuses, such as a roller conveyor or a belt conveyor, for example. The first conveying means 6 conveys the frame portion 16 and a plurality of cases K provided in the frame portion 16, for example, five pieces as one set, and a plurality of sets are continuously arranged with a predetermined gap. A conveyance unit 17 such as a roller or a belt that performs tact conveyance in the direction, and a drive unit 18 such as a motor that operates the conveyance unit 17 are provided.

  Further, the frame portion 16 of the first transport means 6 is provided with first case instruction means 20 positioned corresponding to each case K on the first transport means 6 when the first transport means 6 is stopped. . The first case instructing means 20 instructs the worker X about the case K on the first conveying means 6 to which the goods picked from the frontage 2 should be put. The first case instruction means 20 is, for example, an LED lamp or the like provided for each product input stop position of the case K on the first transport means 6.

  Then, the worker X has a plurality of cases K located at the corresponding positions (opposite positions) of the zone in charge of picking the product, and a set of cases K (for example, five cases) on the first transport means 6. ), The goods picked from the frontage 2 of the corresponding zone are loaded into one case K for which the first case designating unit 20 has issued a loading instruction.

  Note that the number of products picked from the frontage 2 instructed by the frontage instruction means 13 in one picking operation is not limited to one, and may be two or more. When two or more products are picked at the same time, for example, the product quantity to be picked is displayed on the zone monitor 14. A product quantity display means for displaying only the product quantity to be picked may be provided separately.

  Further, the frame section 16 of the first transport means 6 is provided with a completion switch means 19 that is operated by the worker X after the product is put into the designated case K for each zone. The completion switch means 19 is, for example, a tape switch whose longitudinal length is substantially the same as the width of one zone. When the completion switch means 19 is operated, the frontage instruction means 13 issues the next picking instruction.

  Similar to the first transport unit 6, the second transport unit 7 is configured by a conveyor device such as a roller conveyor or a belt conveyor. The second conveying means 7 conveys the frame portion 21 and a plurality of cases K provided in the frame portion 21, for example, five pieces as one set, and a plurality of sets are continuously arranged with a predetermined gap. A conveyance unit 22 such as a roller or a belt that performs tact conveyance in the direction, and a drive unit 23 such as a motor that operates the conveyance unit 22 are provided.

  Further, the frame portion 21 of the second transport means 7 is provided with second case instruction means 25 positioned corresponding to each case K on the second transport means 7 when the second transport means 7 is stopped. . The second case instructing means 25 instructs the worker X on the case K on the second conveying means 7 to which the goods picked from the frontage 2 should be put. The second case instructing means 25 is, for example, an LED lamp provided for each product input stop position of the case K on the second conveying means 7.

  Then, the worker X has a plurality of cases K located at corresponding positions (opposite positions) of the zone in charge of picking up the goods, and a set of cases K (for example, five cases) on the second transport means 7. ), The goods picked from the frontage 2 of the corresponding zone are introduced into one case K for which the second case instruction means 25 has issued an insertion instruction.

  Note that the number of products picked from the frontage 2 instructed by the frontage instruction means 13 in one picking operation is not limited to one, and may be two or more. When two or more products are picked at the same time, for example, the product quantity to be picked is displayed on the zone monitor 14. A product quantity display means for displaying only the product quantity to be picked may be provided separately.

  Further, each of the zone monitor 14, the frontage instructing means 13, the first case instructing means 20, and the second case instructing means 25 is disposed at a position that can be easily seen by the operator X.

  On the other hand, as shown in FIG. 1, the picking system 1 includes a low-frequency product shelf means (low-frequency zone) 26 in which low-frequency products picked by the worker X are stored. The worker X picks the product from the front of the low-frequency product shelf means 26 and places it in the case K in accordance with the picking instruction and the input instruction.

  Furthermore, the picking system 1 includes a control unit 31 that individually controls the first transport unit 6 and the second transport unit 7. That is, the control means 31 individually controls driving and stopping of the first transport means 6 and driving and stopping of the second transport means 7 based on the order information. Conveying means 6, 7, instruction means 13, 20, 25, zone monitor 14, etc. are electrically connected to the control means 31.

  In addition, the control means 31 performs various processes including an allocating process for determining a location including a zone number and an address and automatically allocating products to the frontage of the use zone. Although not shown, the control means 31 is electrically connected to a display means for displaying a setting screen and the like, an input means for inputting information, a storage means for storing information, and the like.

  Here, FIG. 4 is an example of a setting screen for setting shelf conditions displayed on the display means of the picking system 1.

  The screen of FIG. 4 includes an allocation rate display unit 41 that displays a low-frequency product allocation rate (for example, “20”%), and a “low-frequency product allocation rate” that is displayed on the allocation rate display unit 41. And an “allocation rate change” button 42. When the setting operator clicks (operates) the “allocation rate change” button 42, the low-frequency product allocation rate can be input on this setting screen.

  For example, if the low-frequency product allocation rate is set to “20”%, products with an order line number of less than 20% based on the order information will be stored on the storage shelf (for medium-high frequency products). The shelf means 3) is not assigned to the frontage 2 but is assigned to the frontage 26 of the low-frequency commodity shelf means 26.

  The number of orders received (hereinafter simply referred to as “number of rows”) is the number of picking operations (number of picking units) by the worker X, and means the number of accesses (work load) that the worker X accesses the frontage 2. To do. For example, if the number of items that the worker X picks from the frontage 2 in one picking operation is always one, “row number = score”.

  Further, the screen of FIG. 4 displays a frontage corresponding display unit 43 that displays the address of the frontage 2 and the order of assignment (a number indicating the order of assignment), and an “order” for changing the order of assignment displayed on the frontage display unit 43. And an “allocation order change” button 44.

  For example, when setting / canceling a prohibited shelf (prohibited frontage), the setting operator first clicks a frontage portion on the frontage correspondence display unit 43 to be set / released. Then, an item 45 “prohibited shelf setting” and an item 46 “cancelled shelf release” are displayed. Thereafter, the setting operator selects and clicks an item to be set. Clicking on the item 46 for “prohibited shelf setting” indicates that the corresponding frontage 2 is in a prohibited shelf state. Become.

  For example, when changing the allocation order, the setting operator first clicks the “allocation order change” button 44. Then, the set allocation order is cleared. Next, the setting operator clicks the frontage portion on the frontage correspondence display unit 43 in the order of assignment. Then, the allocation order is displayed on the frontage correspondence display unit 43 in ascending order. When all the frontage portions on the frontage display unit 43 (excluding the frontage portion when there are prohibited shelves) are clicked, the allocation order cannot be changed. Although a different allocation order can be set for each zone, a configuration in which only a common allocation order can be set for all zones may be used.

  In addition, the screen of FIG. 4 includes a plurality of zone selection buttons 48 for displaying the zone numbers of the storage shelf means 3 and the number of usable slots (number of available slots), and a check box 49 provided for each zone selection button 48. And a “use zone change” button 50 for changing the use zone, and a selected zone display section 51 for displaying the zone number of one selected zone.

  Then, when the setting operator clicks the “change use zone” button 50, the check box 49 can be checked. In this state, the setting operator inputs a check in the check box 49 corresponding to the zone to be used, and removes the check from the check box 49 corresponding to the zone that is not used.

  Further, the screen of FIG. 4 has a check box 56 for designating two zones located for each of two adjacent zone selection buttons 48. The setting operator inputs a check in the check box 56 when one worker is in charge of two consecutively arranged zones, and one worker is in charge of one zone. If you want to do so, uncheck the check box 56. That is, when the check box 56 for designating the two zones is checked, a mode in which one person is responsible for two zones is set.

  Also, the screen of FIG. 4 shows an allocation rate display unit 57 that displays an upstream zone allocation rate (for example, “20”%) in the one-person two-zone mode, and an upstream zone allocation rate that is displayed on the allocation rate display unit 57. And an “allocation rate change” button 58 for changing.

  When the setting operator clicks (operates) the “change allocation rate” button 58, which is a rate change button, the upstream zone allocation rate (the ratio of the number of picking operations in one of the two zones) is displayed on this setting screen. Can be input. When a numerical value is input to the allocation rate display unit 57 to manually set the allocation rate (workload ratio) of the upstream zone, the allocation rate (workload ratio) of the downstream zone is automatically set. The upstream zone allocation rate displayed on the allocation rate display unit 57 is common to all the set two zones.

  As described above, in the screen of FIG. 4, it is possible to set one worker as a charge for two zones adjacent to each other, and two zones for which one worker is responsible. It is possible to set the ratio of the number of picking operations for each zone (ratio of the number of rows).

  For example, one worker is set in charge of two zones with zone numbers “1” and “2”, and the allocation rate of the upstream zone with zone number “1” is, for example, “20”%. FIG. 5 shows the case of setting as.

  In this case, the zone “1” is a medium frequency shelf, the zone “2” is a high frequency shelf, and basically, products are assigned to all frontage 2 in each zone. In some cases, products may not be assigned to some frontage 2.

  Further, there is no product input from the zone “2” (storage shelf 11) to the transport means 6 and 7 on the zone “1” side, and from the zone “1” (storage shelf 11) to the zone side “2”. There is no product input into the transport means 6 and 7. Further, the lamps of the frontage instruction means 13 shine simultaneously (including substantially simultaneously) in both the zones “1” and “2”, but the pick order is left to the operator X.

  In the screen of FIG. 4, when the input content is changed, the “changed” item 52 becomes a status display. When the “set” button 53 is clicked, the changed input content is set. When the “Cancel” button 54 is clicked, the input content before the change is displayed on the screen of FIG.

  FIG. 6 is an example of a setting screen for inputting product information displayed on the display unit of the picking system 1.

  In the screen of FIG. 6, regarding a special product whose product characteristics are different from those of other products, it is possible to set the group information corresponding to the product characteristics in association with the order information of the special product. Yes. A plurality of products having the same or similar product characteristics can be set for one group information.

  The screen of FIG. 6 has an information display unit that displays the received order information and the input product information as a list.

  The information display unit 61 uses the last received information as the initial display of the target data, but can display information for the past four times by selecting the target data based on the operation of the change button 62. Further, when “all items” or “no group registration” is selected as the display condition and the “display” button 63 is clicked, the target data is displayed in a list.

  After the order information is displayed on the information display unit 61, the setting operator inputs product information according to the received order information as necessary.

  That is, the group information and the fixed information are input so as to correspond to the order information of the product only for the special product whose product characteristics are different from those of other products. However, a product that is already master-managed using the product name as a key is automatically input. As for the frontage number, the frontage number determined in accordance with the number of rows, a predetermined coefficient, and the like is automatically input, but may be input manually. A product without input is processed with no group information and a frontage number = 0. That is, for example, when the master management is not performed or when the master management is changed, the operator enters group name data (for example, “mass goods 1”, “heavy goods 1”, etc.) in the “group” column of the list. When the “Fixed” item is entered, the zone number and address are also entered in the “Fixed Zone No” and “Fixed Address” fields of the list.

  At this time, if you click in the blank area where you want to enter group name data in the “Group” column of the list, a list 65 containing group name data of preset group information is displayed, and “Group” (group name) Data) or “Fixed” is selected and entered.

  In addition, when entering group information that is not in the list 65, clicking the “Group Management” button 66 displays a predetermined group management screen. Click the “Add” button 67 in this group management screen to create a new group information screen. New group information. That is, on the addition screen displayed by the operation of the “add” button 67, the setting operator inputs group name data, zone position data for specifying the allocation range, and frontage position data for specifying the allocation range. The group information can be changed or deleted by operating the “change” button 68, “setting” button 69, “cancel” button 70, “delete” button 71, etc. in the group management screen. Further, when a plurality of group information is set, it is impossible to designate a duplicated frontage between the group information.

  Then, when the input of the product information is completed on the screen shown in FIG. 6, the setting operator clicks the “setting” button 73. Then, the input contents of the list being displayed are set in the information display unit 61.

  At this time, the control means 31 checks the input contents and outputs a message box when an abnormality is detected. By operating the “Cancel” button 74, the information before the setting is displayed again. Specifically, the control means 31 performs a duplication check of the fixed address, and if there is an duplication, notifies the abnormality. Further, the control means 31 determines whether or not the designated frontage obtained from the zone position data and frontage position data of the group information exceeds the total frontage of the ordered product having product characteristics corresponding to the group information, and the total When the number of fronts is exceeded, an abnormality is notified.

  The product allocation is performed by the fixed location setting or the group setting as described above, but the picking workability is affected by the product allocation to the frontage 2.

  Therefore, in this picking system 1, a zone assignment function for each worker is provided, a function for equalizing the hit rate for each worker (equalization of the number of lines) is realized, and a plurality of zones can be created by one worker. When the person in charge is in charge, the function of improving the picking work efficiency is realized by making it possible to set the ratio of the number of picking work for each zone. In the following description, the term “product” refers to a product or one product multiple frontage as a product (since a product with a large number of lines can be set to a plurality of adjacent frontage).

  Using the initial setting function on the setting screen shown in FIG. 4, FIG. 6, etc., (1) setting the number of rows (points) ratio a% in the low-frequency zone, (2) worker assignment setting for each zone (1 work 1) or a plurality of adjacent zones can be set as responsible), and (3) the ratio of the number of rows (points) for each zone within one worker, that is, the upstream ratio M% of the worker in the carrying direction is set. .

  That is, as shown in the flowchart of the system processing of the picking system 1 shown in FIG. 7, in addition to the above (1) to (3), fixed location setting, group setting, use zone setting, prohibited shelf setting, etc. are performed (step 1). .

  Next, the control means 31 of the picking system 1 performs allocation processing of high and medium frequency products and low frequency products after frontage allocation (step 2) by fixed location setting and frontage setting (step 3) by group setting (step 4). .

  High-medium frequency products are products that correspond to (100-a)% of the total number of rows (total points) in descending order of the number of rows (scores), or the total number of high-medium frequency that can be allocated even within the relevant percentages. If it exceeds, it will be up to the corresponding number of units. The low-frequency product is a product other than the high-medium frequency product.

  Next, as [high / medium frequency product processing 1], a sorting process for each worker (picker) is performed (step 5). That is, the distribution of products is performed by the following processing for each worker so that the number of picking operations (number of rows) of each worker or the picking time of each worker is equal (including substantially equal).

  As shown in FIG. 8, (i) products are assigned by worker in order from products with the largest number of rows (scores). (ii) The order of assignment is assigned in order to the worker with the smallest total number of lines currently allocated (total number of points). (iii) Repeat until all products are sorted.

  For each worker, a “multiplying rate” setting function is provided from the worker average number of rows (points) [= average value of the total number of rows (total points) by worker]. The worker who has set the “multiplication rate” distributes the product by the following process with the value of “multiplication rate” × the average number of workers (score) as an upper limit.

  That is, since the number of lines per unit time of each worker varies depending on the experience level of the picking work, for example, on the setting screen, for workers who are not used to the work, for example, 0.7 or more as a “multiplication rate” A numerical value less than 1 is set, and a value that is larger than 1, for example, 1.3 or less is set as the “multiplier rate” for the worker who is used to the work. Then, the number of rows of the workers for which the “multiplication rate” is set in this way is different from the number of rows of the workers for which the “multiplication rate” is not set.

  Next, as a [high / medium frequency product processing 2], one worker's multiple zones are distributed (step 6). That is, at the time of the sorting process for each worker in the above step 5, the worker who is “one worker and a plurality of zones” is processed from the zone having a high ratio of the number of rows (scores) by the following processing. The products are sorted by zone so that they can be allocated sequentially.

  As shown in FIG. 9, for example, a case where one worker is set to take charge of two adjacent zones and a zone with a high ratio of the number of rows (high frequency zone) is a zone downstream in the transport direction will be described. To do.

  (i) In step 5, the number of product lines (points) allocated sequentially is cumulatively added, and the value exceeds the “average number of rows (scores) in the downstream zone of the worker's conveyance direction” according to Equation 1 shown in FIG. To the downstream zone of the two zones. (ii) At the time of the sorting process for each worker in step 5, the products assigned to the worker after (i) are assigned to the upstream zone in the two zones.

  Next, as [High / Medium Frequency Product Processing 3], adjustment processing of the number of products (frontage) by zone is performed (Step 7). In other words, the tuning is adjusted according to the number of effective frontage per zone (preset number of usable frontage), and the product is set so that the number of frontage (number of products) distributed to each zone is less than the effective frontage. Adjust by swapping.

  In the process so far (high and medium frequency product processing 1 and 2), products are sorted by zone, but the number of frontage (number of products) to be sorted is limited in the implementation zone. Therefore, these are adjusted to values that can be assigned. The adjustment process in step 7 is a process between zones, and is not related to the allocation by worker.

  As shown in FIG. 10, for example, in the zones where the zone numbers are “1” to “8”, the effective frontage number (available frontage number) is set to “18”, and the zone numbers are “9” to “16”. Now, a case where the effective frontage number (available frontage number) is set to “24” will be described.

  As shown in FIG. 11, a zone that exceeds the effective frontage number is referred to as a K zone, and a zone that has an effective frontage number of −1 or less and has a free frontage is described as a Y zone. (i) Extract multiple products (for example, 2 products) with a small number of rows (scores) from one K zone, and select the same number of products (the closest value if there is no same number) from all Y zones. Select and replace two products in the K zone and one product in the Y zone on the data. (ii) The replacement process of (i) is repeated until there is no K zone.

  Next, zone optimization processing is performed as [High / Medium Frequency Product Processing 4] (Step 8).

  Basically, the processing of the high and medium frequency product processing 1 to 3 is performed. However, in order to perform processing with “the closest value when there is no same number” in the replacement of the product in the high and medium frequency product processing 3 (step 7), Deviation occurs in the ratio between zones (work burden ratio). In order to correct this, the following processing is performed.

  (i) 1 worker 1 zone: average number of rows (score) by worker, (ii) 1 worker 2 zone (upstream): 1 worker 2 zone (upstream) average row number (score), ( iii) One worker, two zones (downstream): The average number of rows (points) in one worker, two zones (downstream). For each worker, if the “multiplier rate” is set from the worker average number of rows (points) [= average number of rows (total points) by worker], this value is multiplied by It is a value multiplied by "rate".

  Then, in each of (i) to (iii), the product of the difference between the “excessive zone” and the “excessive zone” from the average value is replaced by “one-to-one”, thereby averaging for each zone. To implement. This process is repeated until “all zones are within x% of the average value” or “is set for n times”. Note that x% and n times are set values, respectively.

  Next, a frontage assignment process in the zone is performed as [High / Medium Frequency Product Process 5] (Step 9). That is, for example, the products assigned to each zone in the high and medium frequency product processing 1 to 4 are assigned to the frontage in the zone in the descending order of the number of rows (scores) in accordance with a preset assignment order (priority order).

  Here, regarding the two zones handled by one worker, the allocation order in the upstream zone, which is a high frequency shelf, and the allocation order in the downstream zone, which is a medium frequency shelf, should be set different from each other. Is preferred. That is, for example, as shown in FIG. 12, in the downstream zone, the order of the center of the shelf is set in the early allocation order, and in the upstream zone, the order of the shelf side in the downstream zone is set in the early allocation order. By setting in this way, the burden on the operator's attention is reduced.

  According to the picking system 1, it is possible to set one worker as a charge for a plurality of zones adjacent to each other, and for each zone related to the plurality of zones handled by one worker. Since it is possible to set the picking work number ratio, for example, the picking work number ratio can be appropriately set so that the number of picking work on the downstream zone side is larger than that on the upstream zone side. Workability can be improved.

  In the above embodiment, the case where the adjustment processing of the number of products by zone is performed as [high / medium frequency product processing 3] has been described. However, as shown in FIG. By adjusting the number distribution ratio according to the worker up to the above, the adjustment processing of the number of products according to the zone may not be performed.

  In addition, a configuration has been described in which one worker can be set in charge of two zones that are continuously arranged along the longitudinal direction of the storage shelf means 2 and are adjacent to each other. One worker may be set as a person in charge for three or more zones arranged side by side.

  Further, the conveying means for conveying the case K into which the goods picked from the frontage 2 are put is not limited to two parallel lines, and may be one line or three lines or more. Moreover, the structure etc. which place the goods picked from the frontage 2 directly on an upper surface, and convey it, without using a case may be sufficient.
