DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article picking method suitable for use in a distribution center or the like.

[0002]

2. Description of the Related Art Conventionally, when an article is taken out of a storage facility and stored in a container, a method of displaying the type and quantity of the article to be taken out of the storage facility is to divide the storage facility into a plurality of zones, and a plurality of containers. To each zone,
For each zone, the storage frontage and the quantity to be taken out of the input articles are displayed for one container. Further, the input articles for one container are displayed before the container arrives at the zone, and the articles are pre-fetched to the temporary storage table before the container arrives. That is,
(1) and (2).

(1) Creation of picking data (Table 3) Order data of each delivery destination (store) is first stored in one for each delivery route.
Cars are grouped together (in units of delivery vehicles), and then order data for a plurality of vehicles are grouped together to make a unit for picking processing (in units of batches). The order data is processed in batch units, and picking data as shown in Table 3 (storage frontage (type), number of items to be taken out, number of containers, allocation of items to each container) as shown in Table 3 is created.

[0004]

[Table 3]

(2) Picking work (FIGS. 12 to 15) Containers are sequentially conveyed to each zone by one knit consisting of the number of pieces (here, 6 pieces) which fall into one zone.

When the picking operation is started, all the picking data of the container to be picked first in each zone is displayed (FIG. 12 (a)). In two zones, ten items are displayed in two rows, and in two zones, the picking data of containers (9 in one row, eight in three rows and two rows) is displayed on the picking quantity display of each corresponding frontage (the same applies to other cases). (FIG. 12 (a)).

In accordance with the display, the operator takes out a required number of articles from each frontage of each zone and temporarily puts the articles on a temporary table of each zone.

The containers are conveyed to the picking zone in a lump for each of the knittings, and are stopped when the containers in the knitting arrive at the zone where the articles should be stored. The input container indicator corresponding to the container into which articles are to be input among the containers of the same organization is turned on. FIG.
In (b), of the containers arriving in one zone, the input indicator of the container is lit. The operator puts the articles that have already been temporarily stored in the temporary storage table in one zone into the lit container of the display.

When the articles in the zone are to be loaded into another container among the containers of the same organization, the picking data of the container is displayed, and the loaded container indicator corresponding to the container is turned on. FIG.
In 2 (c), of the containers arriving at one zone, picking data for containers (10
(6 pieces of 3 rows and 2 rows) are displayed on the picking quantity indicator of each corresponding frontage, and the input indicator of the container is lit. An operator takes out an article from each frontage and puts it into the lit container of the above-mentioned display.

Similarly, the picking operation is repeated in other zones (FIG. 12 (d), FIGS. 13 to 15).

[0011]

However, the prior art has the following problems. After calculating the required number of containers from the order (type, quantity) for one delivery destination (store) in advance, it is necessary to allocate and calculate the articles to be stored in each container.

The allocation of the articles to each container is determined by simply comparing the volume of the articles and the volume of the container. Therefore, when the articles are actually stored in the container, depending on the shape of the articles,
Inconveniently, too many containers may be allocated, or conversely, items may overflow from the containers.

[0013] Since it is not permissible to store even the same delivery destination in a container other than the assigned container, even if there is an extra container as described above, the extra container cannot be removed by merging.

[0014] It is possible to preload articles into a temporary storage table or the like for only one container.

An object of the present invention is to simplify the creation of picking data, improve the efficiency of storing articles in each container, and improve the efficiency of picking.

[0016]

According to a first aspect of the present invention, there is provided a method for picking an article, wherein the article is taken out of a storage facility and stored in a container, wherein the storage facility is divided into a plurality of zones, In this case, a container group with a plurality of article storage fronts shall be used, and a group of containers for a plurality of delivery destinations shall be collectively transported to the above zones sequentially and independently for each zone. Of the container group corresponding to the order of the same delivery destination among the group of containers to be delivered to the container, and the display of the quantity to be taken out is given, and the input indication is given to all of the containers for the destination in the container group. , Multiple containers for the same delivery destination
When crossing the adjacent zone of
Destination container, and the first container is
Attach the above-mentioned unload quantity display and input display at the entered zone.
And the same applies to the upstream zone in that zone.
This is to indicate that there is a container for one delivery destination .

[0017]

[0018]

According to the first aspect of the present invention, the following:
Has the effect of 1 container for picking quantity
Instead of displaying them one at a time
And for all containers at the destination
Since the input display is made, the worker can
If there is, it can be stored in any container.
You.

In the preparation of picking data, it is sufficient to calculate the required number of containers for the delivery destination from the order (type, quantity) for one delivery destination in advance as described above. It becomes unnecessary. That is, creation of picking data is simplified.

The worker can store the articles in appropriate ones of the containers according to the amount of the articles stored in the containers corresponding to the same delivery destination, and finally remove the excess container. You can also. That is, the efficiency of storing articles in each container can be improved.

The pre-fetching of the articles on the temporary storage table or the like can be performed collectively for one delivery destination (for a plurality of containers). In addition, since the picking display of a large number of articles is displayed at a time, the work efficiency of picking can be improved.

Even if containers for the same delivery destination cross over to a plurality of adjacent zones, the display of the quantity taken out and the input display are given in the zone where the leading container is carried in, and the same is applied to the upstream zone in the zone. By indicating that there is a container for the delivery destination, the operator can definitely recognize all of the multiple containers in the adjacent zone as being the containers for the same delivery destination.

As shown in FIG. 1, the bulk picking device 10 is configured by installing a roller conveyor 12 in front of a fluidized shelf 11 (storage facility). The fluidized shelf 11 is divided into a plurality of zones (article storage sections) along the transport direction of the roller conveyor 12, and the roller conveyor 12 collects container groups for a single delivery destination or for a plurality of delivery destinations. And sequentially transported to each zone. In each zone, the articles 1 removed by the operator from the fluidized shelves 11
4 is stored in each container 15 of the container group. In this way, when each container 15 of the container group passes through all the zones, predetermined bulk picking ends. In addition, the rose picking device 10 includes a temporary placing table 13 that can move along the roller conveyor 12.

Hereinafter, the fluidized shelf 11 and the roller conveyor 1 will be described.
2. The configuration of the temporary placing table 13 will be described.

(A) Fluid shelves 11 (FIGS. 1 and 2) The fluid shelves 11 are provided with inclined conveyors 21 for storing articles (products) to be picked up in a plurality of rows and a plurality of stages. Corrugated cardboard cases 16 containing articles 14 of the same type are temporarily stored in each article storage frontage formed by each of the inclined conveyors 21. And
In this embodiment, the article storage frontage for five rows is defined as one zone. Therefore, in this embodiment, the inclined conveyor 2 is used.
If 1s are arranged in three rows of upper, middle and lower rows in each row, an article storage frontage for all 15 types of 5 rows and 3 rows is provided for each zone.

At the end of each inclined conveyor (article storage frontage) 21, a picking quantity display 22 for displaying the number of articles taken out from the frontage, and a completion of taking out to inform a computer (picking control device) that the completion of the taking out. Button 23.

Further, at the stop position of each container 15 on the roller conveyor 12, an input container display 24 for displaying that the container 15 stopped at the stop position should input an article, and a computer for indicating that the input is completed. Input complete button 25 to be sent to (picking control device)
And is installed.

Further, at the center of each zone of the roller conveyor 12, a subsequent container presence indicator 26 is provided. When the container 15 for the same delivery destination crosses a plurality of adjacent zones, the succeeding container presence indicator 26 displays the container 15 for the same delivery destination in the upstream zone in the zone where the leading container 15 is carried in. This is to indicate that there is.

The fluidizing shelf 11 is provided with one picking work lamp 27 in each zone. Picking work light 27
Indicates that the zone is being picked, and is lit when any of the picking quantity indicators 22 in the zone is lit, and all of the lit picking quantity indicators 22 are lit. Turns off when turned off.

(B) Roller Conveyor 12 (FIGS. 1 and 2) The roller conveyor 12 is arranged along the front surface of the fluidized shelf 11 and starts and stops smoothly while keeping the containers 15 of the container group in close contact with each other. , Sequentially to downstream zones.

The driving of the roller conveyor 12 can be independently stopped for each zone. Then, it is assumed that the container group in the zone is started on condition that the loading completion button 25 of the zone is turned on and the conveyor group in the downstream zone has been started.

More specifically, the roller conveyor 12 includes a driving force transmitting member for transmitting a roller driving force over a plurality of zones, a driving cutting device for bringing the driving force transmitting member into frictional contact with the roller for each zone, And a brake device for bringing the brake member into frictional contact with the roller every time.

That is, in the roller conveyor 12,
When the group of containers to be stopped has arrived in the zone,
When the presence detection photo switch 28 provided on the roller conveyor 12 detects, the drive cutting device separates the driving force transmitting member from all the rollers in the zone by the command from the conveyor control device, and at the same time, the braking device A brake member is pressed against all the rollers in the zone to brake all the rollers and stop the container group. Then, as described above, on condition that the loading completion button 25 of the zone is turned on and the conveyor group in the downstream zone has already started, the brake device issues a command from the conveyor control device, except for the front end of the zone. By releasing the braking that was applied to the rollers in the above, the first container of the container group was braked by releasing the braking, and the drive cutting member pressed the drive transmission member against the rollers other than the front end by the drive cutting device to drive the rollers other than the front end. Then, a driving force is applied to another container, and the subsequent container is brought into close contact with the first container. Then, after a lapse of a certain period of time (for example, about 2 seconds), the braking applied to the roller at the front end of the zone is released by the brake device, and the driving force transmitting member is also applied to the roller at the front end by the drive cutting device. By pressing, the roller at the front end is also driven to start the group of containers and carry them out to the downstream zone.

(C) Temporary placing table 13 (FIGS. 1 to 6) The temporary placing table 13 temporarily places the articles 14 taken out of the fluidized shelf 11 and is movable along the transport direction of the roller conveyor 12. Guided by In addition, temporary table 1
3 is a side approaching the roller conveyor 12 and a flow shelf 11
And can be moved between the side approaching.

That is, as shown in FIGS. 3 and 4, an upper guide rail 32 and a lower guide rail 33 are provided on the front surface of the support frame 31 constituting the roller conveyor 12 along the conveying direction of the conveyor 12. Has been extended. On the other hand, an upper horizontal roller 35, an upper vertical roller 36, and a lower vertical roller 37 are pivotally attached to the leg 34A of the traversing frame 34. Then, the traversing frame 34 includes the fluidized shelf 1
1 is provided for each zone, and the upper horizontal roller 35
Is supported on the lower horizontal guide surface of the upper guide rail 32 to enable rolling, and the upper vertical roller 36 is connected to the upper guide rail 3.
2 between the left and right vertical guide surfaces so as to be rollable, and the lower vertical roller 37 is pressed against the outer vertical guide surface of the lower guide rail 33 to be rollable. As a result, the longitudinal direction of the guide rails 32, 33 is obtained. Is guided so as to be movable along the conveying direction of the conveyor 12. Thereby, in each zone of the fluidized shelf 11, the temporary placing table 13 can be moved to the vicinity of the article storage frontage from which articles are taken out, or to the vicinity of the stop position of the container to which articles are put. You.

The traversing frame 34 is provided with a pair of slide bases 38 extending on the left and right sides in a direction perpendicular to the conveying direction of the conveyor 12.
Slide rail 3 slidably inserted into 8, 38
A temporary tray 13 in the form of a tray is supported via 9, 39. The temporary placing table 13 is fixed to slide rails 39, 39 slidable with respect to the slide bases 38, 38, and extends along a direction orthogonal to the conveying direction of the conveyor 12.
By pushing the slide rail 39 into the slide base 38, the slide rail 39 can be moved to the side closer to the conveyor 12, and by pulling the slide rail 39 out of the slide base 38, it can be moved to the side closer to the flow shelf 11. . Thereby, the temporary placing table 13 can be moved in each zone of the fluidized shelf 11 in the vicinity of the article storage frontage from which articles are taken out, or in the vicinity of the stop position of the container to which articles are put. You.

Hereinafter, the operations of picking from the fluidized shelf 11 using the bulk picking device 10, loading into the container 15, and inspection will be described.

(A) Picking (1) Preparation of picking data (FIG. 1, FIG. 2, Table 1) Order data of each delivery destination (store) is first stored in one for each delivery route.
The delivery vehicles are grouped together (in units of delivery vehicles), and then order data for a plurality of vehicles are grouped together and made into a unit for picking processing (in units of batches). Processing order data in batches,
Picking data as shown in Table 1 (item storage frontage (product type), number of items to be taken out, number of containers) for each delivery destination (store) is created.

[0040]

[Table 1]

Further, the planned stock quantity after picking of the article storage frontage to be picked in each delivery vehicle unit which is the inspection unit is calculated. This planned stock number is the planned number of remaining articles in one of the cardboard box cases 16 enrolled in each article storage frontage, which is at the forefront and is the source of articles at the time of next picking.

The containers are grouped into groups (compositions) having the maximum number (here, six) in a single zone, and are sequentially conveyed to each zone. At this time, containers of a plurality of delivery destinations (stores) are collectively configured to form one knitting.
The container of one delivery destination (store) should not span two knittings.

However, when the number of containers at one delivery destination (store) exceeds the above maximum number (6) and is equal to or less than the maximum number of two zones (12), the correlation between one delivery destination and the next is determined. Are formed. At this time, the containers of the other delivery destinations have different organization.

If the number of containers at one delivery destination (store) exceeds the maximum number (6) and exceeds the maximum number of two zones (12), the first to twelfth containers are used. As described above, one delivery destination constitutes two knittings that make a correlation with each other. Then, the 13th and subsequent containers are treated as newly independent delivery destination containers on the picking data, and an independent composition is formed from these two compositions.

(2) Picking work (FIGS. 5 to 10) When the picking work is started, the picking control device
All picking data of the delivery destination (store) picked first in each zone is displayed. In FIG. 7 (a), the picking data of store A in zone 1 (5 in the first row and 5 in the second row, 10 in the second row), and the picking data of store B in the second zone (9 in the first row, (8 in 3 stages 2 stages, 6 in 5 stages 1 stage)
Is displayed on the picking quantity display 22 of each corresponding article storage frontage (the same applies to other cases) (FIG. 7A).

In each zone, the worker takes out a required number of articles from each article storage frontage in each zone according to the above display and temporarily stores them on the temporary placing table 13.

At this time, the worker moves the traversing frame 34 of the temporary placing table 13 along the conveying direction of the conveyor 12, and positions the temporary placing table 13 near the article storage frontage displayed as the article take-out source. . Further, the worker pulls out the slide rail 39 supporting the temporary storage table 13 from the slide base 38, and positions the temporary storage table 13 immediately near the article storage frontage from which the article is taken out. Thereby, the worker can transfer the articles from the article storage frontage to the temporary storage table 13 without walking, and thus can easily and quickly take out the predetermined articles (FIG. 6).
(A)).

When there are a plurality of article storage fronts displayed by the picking quantity indicator 22 in the zone, the worker in each zone sequentially moves the temporary placing table 13 to each article storage frontage as described above. While approaching, the temporary storage to the temporary storage table 13 from each article storage frontage is repeated (FIG. 5A).
(C)).

As described above, the required number of articles for the delivery destination (store) first picked up in each zone are collected on the temporary placing table 13.

(B) Loading (FIGS. 5 to 10) (1) The containers 15 are grouped for each knitting and are sequentially conveyed to the picking zone, and arrive at the zone where articles should be stored in the containers 15 in the knitting. Then it is stopped. The input container indicator 24 corresponding to the container 15 of the delivery destination (store) into which articles are to be input among the containers 15 of the same organization is turned on. In FIG. 7B, the input container indicators 24 of the first and second two containers 15 which are the containers of the store A are lit. The operator puts the articles that have already been temporarily stored on the temporary storage table 13 into the appropriate ones of the containers 15 whose display is turned on. At this time, the worker looks at the contents of the container 15 and makes a selection such as putting them together in one container 15 or putting large and small articles separately so that they are not easily damaged, so that the cargo is not easily collapsed. An appropriate container 15 is selected based on the standard (FIG. 5D).

At this time, the worker moves the traversing frame 34 of the temporary placing table 13 along the conveying direction of the conveyor 12, and positions the temporary placing table 13 near the container 15 displayed as the article input destination. Further, the operator pushes the slide rail 39 supporting the temporary storage table 13 into the slide base 38, and positions the temporary storage table 13 immediately adjacent to the container 15 to which the article is to be input. This allows
The worker can transfer the articles from the temporary placing table 13 to the container 15 without walking, and temporarily enters the articles because the temporary placing table 13 is not fixed in a long range along the conveyor 12. There is no need to go through the placing table 13, it is possible to enter the side of the temporary placing table 13 and approach the container 15, and as a result, a predetermined article can be easily and quickly input (FIG. 6B).

(2) When there is an order for an article in the zone for another delivery destination (store) among the containers of the same organization, the picking data of the delivery destination (store) is displayed and the delivery data is displayed. When the input container indicator 24 corresponding to the container 15 at the destination (store) is turned on (FIG. 7C), the picking data of the B store (10 units for 2 units and 6 units for 3 units) is displayed. Picking quantity indicator 22 for each frontage
And the input container indicators 24 of the third, fourth, and fifth containers 15 that are the containers of the B store are lit. The worker places the articles from the frontage
And puts it into an appropriate one of the lit containers 15.

Similarly, the picking operation is repeated in other zones (FIG. 7D, FIGS. 8 to 10).

(3) When the number of containers at one delivery destination (store) exceeds the maximum number (6) in a single zone and is equal to or less than the maximum number of two zones (12) (FIG. 8 ( In the case of a), the D store has 7 containers), as described above, constitutes two knittings which are correlated with each other as the container knitting, and the picking quantity indicator 22 is displayed for the first knitting knitting at the delivery destination (store). The display operation of the input container display 24 is performed. In FIG. 8 (a), the preceding container organization of the D store has arrived in the zone, and there is one remaining container upstream. According to the above picking data, for store D,
In the zone, 5 units from 2nd stage and 12 stages from 5 stages and 2nd stage
Picking eight articles from three individual, five-tiered units. These articles have already been temporarily stored on the temporary placing table 13 in FIG. Then, when the container of store D arrives in the zone, all the input container indicators 24 corresponding to the container of store D are turned on, and the succeeding container presence indicator 26 is turned on in this zone, and Also displays that there is a container 15 for store D. Therefore, the worker puts an article into an appropriate one of the seven containers 15 of the zone container 15 and the upstream container 15.

When the number of containers at one delivery destination (store) exceeds the maximum number (6) in a single zone and exceeds the maximum number of two zones (12) (for example, 15 containers). As described above, the first to twelfth containers are composed of two correlators that form a correlation between the first and twelfth containers, and the thirteenth and subsequent containers are newly configured as containers 15 for independent delivery destinations. Treat as something. Accordingly, for the first to twelfth containers 15, the display operations of the picking quantity display 22 and the input container display 24 are performed for the preceding container knitting. The input containers are displayed by turning on all the six input container indicators 24 corresponding to the containers 15 and turning on the subsequent container presence indicators 26 in the zone. Then, for the container 15 after the thirteenth,
The display operation of the picking quantity display 22 and the input container display 24 is performed as an independent container organization on the picking data, and articles are input to the thirteenth and subsequent containers 15 in the zone where these containers 15 are registered. Light the picking quantity indicator 22 on the power frontage,
Further, the input container display 24 corresponding to each of the containers 15 is turned on to display the input container. Here, the container for two zones was set as the limit, but it is not limited to this,
One zone or three zones may be used. When one zone is set, the subsequent container presence display is not required.

It should be noted that the picking quantity indicator 2 for each zone
2. The lighting timing of the input container display 24 is as follows.

That is, the picking quantity indicator 22 indicates that the delivery destination (store) to be picked next after the loading completion button 25 of the delivery destination (store) to be picked into the container 15 is pressed. Display for This display disappears when the corresponding takeout completion button 23 is pressed.

The input container display 24 indicates that the container 15 to be inserted in the zone starts in the upstream zone (at this time, since the container 15 in the zone has also started, there is no mistaken insertion). ). When the input container indicators 24 are turned on for a plurality of containers 15 at the same delivery destination, pressing any one of the input completion buttons 25 corresponding to them turns off all the input container indicators 24. .

(C) Inspection (FIG. 1, FIG. 2, FIG. 7 to FIG. 11, Table 2) (1) An inspection container 40 is provided in the last container 15 of the containers 15 for one delivery vehicle as an inspection unit. Is followed. The inspection container 40 is composed of one container, and the inspection is performed in a zone where the inspection container 40 has arrived. That is, the inspection container 40 is registered between the last container 15 of the containers constituting the preceding inspection unit and the first container 15 among the containers constituting the subsequent inspection unit. An inspection space for one zone is opened, and inspection is performed in the zone where the inspection space has arrived.

[0060]

[Table 2]

The inspection container 40 is transported not for storing articles but for notifying an operator or a picking control device (computer) that inspection is to be performed. The picking control device recognizes in which zone each container knitting is present from the output of the in-stock detection photo switch 28, whereby it is possible to know the arrival of the inspection container 40 in each zone.

(2) In the zone where the inspection container 40 has arrived (to be precise, when the inspection container 40 has started in the preceding zone), one of the inspection unit containers 15 corresponding to the inspection container 40 For the article storage frontage to which the articles have been supplied, the planned quantity calculated in advance in the above-described picking data creation stage is displayed on the picking quantity display 22 which is also used as the planned quantity display. FIG. 8 (c)
Then, the inspection container 40 has arrived at the zone.
At this time, the expected number of zones shown in Table 2 (5 in 1 row of 2 stations, 14 in 2 rows of 3 stations, 18 in 5 rows of 2 rows, 5 rows of 3 rows
12) are displayed on the picking quantity display 22.
The worker in charge of the zone displays the expected number of items, and displays the number of actual items in the storage frontage of the corresponding article (a single cardboard box case 16).
(The remaining number of articles in the box, the fraction of less than one box) is checked to see if they match, and if they match, the unpacking completion button 23 and the inspection check button that is also used are pressed. When the inspection confirmation button is pressed, the display of the planned stock quantity of the article storage frontage disappears, and the picking control device (computer) recognizes that the stock quantities match. When the display of all the article storage frontages displayed with the planned stock quantity is erased, the inspection in the zone is completed.

In the zone where the article storage frontage is displayed during the display of the planned stock quantity, the picking work lamp 27 is turned off to inform the operator that the inspection is being performed.

The inspection container 40 has a label indicating that it is an inspection. A bar code is also printed on this label. Inspection container 4
When 0 passes through all the picking zones, it branches off to a different route from the delivery container 15.

(3) As a result of the inspection in (2) above, if the planned stock quantity and the actual stock quantity do not match, the worker receives the miss picking list shown in FIG. The container 15 of the delivery destination (store) to which the picking type is to be input is searched, and those whose actual storage quantity in the container 15 does not match the ordered quantity are corrected (added or reduced).

The miss picking list shown in FIG. 11A shows four zones, three stations and two stations when the inspection unit is the second car.
It is a figure which shows the miss picking which occurred in the articles (miss picking varieties) taken out from the article storage frontage of the step. Then, in this list, among the delivery destinations (stores) corresponding to the second car, the delivery destination (store) to which this mispicking list type is to be input, and the number of orders of the type from the delivery destination (store) , The number of assigned containers, and the stowage station number (stowage ST-No) of the second car.

According to this method, since it is immediately recognized that the picking has been performed after picking, it can be corrected immediately. During this time, the picking can be continued, so that the picking work does not have to be interrupted, and there is no possibility that the product will be shipped incorrectly.

In this embodiment, the inspection unit is one delivery vehicle unit. However, the inspection unit may be one batch unit or one day unit. FIG. 11B is a miss picking list showing miss picking when the inspection unit is the 15th batch.

Hereinafter, the operation of the present embodiment will be described. Instead of displaying the picking quantity for each container, the orders for one delivery destination are displayed collectively, and all containers 15 of the delivery destination are input and displayed. If so, the articles may be stored in any container 15.

In the preparation of the picking data, it is sufficient to calculate the required number of containers for the destination from the order (type, quantity) for one destination in advance as described above. Becomes unnecessary. That is, creation of picking data is simplified.

The worker can store the articles in an appropriate one of the containers 15 according to the amount of the articles stored in each of the containers 15 corresponding to the same delivery destination. 15 can also be removed. That is, the efficiency of storing articles in each container 15 can be improved.

The prefetching of the articles on the temporary storage table 13 or the like can be performed for one delivery destination (for a plurality of containers) at a time. In addition, since the picking display of a large number of articles is displayed at a time, the work efficiency of picking can be improved.

Even if the containers 15 for the same delivery destination cross over to a plurality of adjacent zones, the display of the quantity to be taken out and the input display are given in the zone where the leading container 15 is carried in, and the upstream zone is also provided in the zone. By displaying that there is a container 15 for the same delivery destination, the operator can definitely recognize all of the multiple containers 15 over the adjacent zone as being the containers 15 for the same delivery destination.

Note that the loose picking device 10 of this embodiment is
Is not limited to the display of the quantity taken out and the container input display at the same delivery destination (store), but also the display of the quantity taken out and the container input display at the unit of each container based on the picking data as shown in Table 3. May be.

[0075]

As described above, according to the present invention, the creation of picking data can be simplified, the efficiency of storing articles in each container can be improved, and the efficiency of picking work can be improved.
