2. Description of the Related Art Conventionally, as a method for inspecting whether or not the type and quantity of the stored article match the order content when the article is taken out from the storage facility according to the order content (type and quantity) and stored in a container, , After the last container of the multiple containers that make up the inspection unit (for example, the containers for all delivery vehicles) passes through all zones, the actual inventory quantity and the planned inventory quantity at each goods storage frontage in all zones are checked. I am going to do it.

[0003]

However, the prior art has the following problems. Both the picking time period and the inspection time period are necessary because the collation inspection work is performed again after the picking work for all the containers constituting the inspection unit is completely completed in all the zones. Moreover, an inspection worker is required in addition to the picking worker, which hinders picking productivity.

The inspection is performed after all the containers constituting the inspection unit have passed through all the zones, and it takes a relatively long time to correct a picking mistake based on the inspection result, which hinders the picking productivity.

It is an object of the present invention to improve picking productivity when inspecting whether or not the type and quantity of picked articles match the order contents.

[0006]

In the inspection method in the article picking system for inspecting whether or not, the storage facility is divided into a plurality of zones, each zone is provided with a plurality of article storage fronts, and each of the plurality of containers constituting the inspection unit is used. Are sequentially conveyed to each of the above zones, and the articles taken out from the article storage frontage of the type corresponding to the order content are stored in each container, and the last container of the plurality of containers constituting the inspection unit is in each zone. Each time it passes, the actual inventory quantity and the planned inventory quantity at each article storage frontage in the zone are collated. In are those varieties and quantity of goods stored in all container constituting the inspection unit has to be determined that it was not match the order contents.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the inventory storage collation is performed by comparing the inventory quantity with an article storage frontage in which articles are supplied to any of a plurality of containers constituting the inspection unit. It was done only in.

The present invention according to claim 3 is the same as the present invention according to claim 1, further comprising: a last container among a plurality of containers forming a preceding inspection unit and a plurality of containers forming a subsequent inspection unit. An inspection space for a single zone is opened between the container and the earliest container, and the stock quantity is checked in the zone where the inspection space has arrived.

According to a fourth aspect of the present invention, in addition to the first aspect of the present invention, a picking quantity indicator provided in each of the article storage fronts has a picking quantity of the article to be taken out into each container and the inspection. The planned inventory quantity for the item is switched and displayed.

[0010]

According to the present invention described in claim 1,
Has the effect of. Each time the last container of the plurality of containers forming the inspection unit passes through each zone, whether or not the plurality of containers forming the inspection unit are picked correctly for the type and quantity of the zone. Will be inspected. That is, it is possible to inspect each picking zone unit during picking. Therefore, when a plurality of containers forming the inspection unit have passed through all zones, the picking to each of the containers is completed and the inspection is completed at the same time, and it takes almost no inspection time. Further, since the picking operator also performs the inspection in parallel, the inspection operator is not required.

As shown in FIG. 1, the bulk picking device 10 is constructed by installing a roller conveyor 12 in front of a fluidized shelf 11 (storage facility). Then, 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 collectively collects a container group for a single delivery destination or a plurality of delivery destinations. It is sequentially conveyed to each zone and stopped. In each zone, an article 1 taken out by the worker from the fluidized shelf 11
4 is stored in each container 15 of the container group. In this way, each container 15 of the container group passes through all the zones, whereby the predetermined variable picking is completed. The bulk 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
2. The structure of the temporary table 13 will be described.

(A) Fluidized Shelf 11 (FIGS. 1 and 2) In the fluidized shelves 11, inclined conveyors 21 for storing articles (commodities) to be individually picked are arranged in a plurality of rows and a plurality of stages. A corrugated cardboard case 16 accommodating articles 14 of the same type is temporarily stored in each of the article storage openings formed by each of the inclined conveyors 21. And
In this embodiment, the article storage fronts for five rows are defined as one zone. Therefore, in this embodiment, the inclined conveyor 2
If 1s are arranged in 3 rows of upper, middle, and lower in each row, each zone is provided with an article storage front for all 15 types of 5 rows and 3 rows.

At the tip 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 the computer (picking control device) that the takeout is completed And a button 23.

At the stopping position of each container 15 on the roller conveyor 12, a loading container indicator 24 for indicating that the containers 15 stopped at the stopping position should be loaded, and a computer for indicating that loading has been completed. Insertion completion button 25 to notify (picking control device)
And are installed.

Further, a succeeding container presence indicator 26 is installed at the center of each zone of the roller conveyor 12. When the containers 15 for the same delivery destination cross over a plurality of adjacent zones, the succeeding container presence indicator 26 indicates the container 15 for the same delivery destination in the upstream zone in the zone in which the leading container 15 is loaded. Is displayed.

Further, the fluidized shelf 11 is provided with one picking work lamp 27 in each zone. Picking work light 27
Indicates that the zone is in the process of picking, 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 displayed. 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 smoothly starts and stops while closely contacting each container 15 of the container group. , Sequentially, to the downstream zone.

The roller conveyor 12 can be independently driven and stopped for each zone. Then, the container group of the zone is started on condition that the loading completion button 25 of the zone is turned on and the conveyor group of the downstream zone is already started.

Specifically, the roller conveyor 12 includes a driving force transmission member for transmitting the roller driving force over a plurality of zones, a drive cutting device for frictionally contacting the driving force transmission member with the roller for each zone, and a zone. A braking device for frictionally contacting the brake member with the roller can be provided for each unit.

That is, in the roller conveyor 12,
When the containers that should be stopped have arrived in the zone,
When the photo detection switch 28 for detecting a load provided on the roller conveyor 12 detects it, the drive cutting device separates the driving force transmission member from all the rollers in the zone according to a command from the conveyor control device, and at the same time, the brake device detects the driving force transmission member. The brake members are pressed against all the rollers in the zone to brake all the rollers and stop the container group. Then, as described above, on the condition that the closing completion button 25 of the zone is turned on and the conveyor group of the downstream zone has already started, the brake device issues a command other than the front end of the zone by a command from the conveyor control device. By releasing the braking applied to the rollers with, the top container of the container group is braked, and the drive cutting device presses the drive transmission member against the rollers other than the front end to drive the rollers other than the front end. The driving force is applied to the other container to bring the succeeding container into close contact with the leading container. After a certain period of time (for example, about 2 seconds), the braking device releases the braking applied to the roller at the front end of the zone, and the drive cutting device also causes the driving force transmission member to be applied to the roller at the front end. By pressing, the roller at the front end is also driven to start the container group and carry it out to the downstream zone.

(C) Temporary Storage Table 13 (FIGS. 1 to 6) The temporary storage table 13 is for temporarily storing the articles 14 taken out from the fluidized shelves 11 and is movable along the transport direction of the roller conveyor 12. Be guided by. In addition, temporary table 1
3 is the side approaching the roller conveyor 12 and the fluidized shelf 11
It is possible to move between the side approaching and.

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. It 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 portion 34A of the transverse frame 34. Then, the transverse frame 34 includes the fluidized shelf 1
The upper horizontal roller 35 is provided for each zone 1

A tray-shaped temporary placing table 13 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 along the 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 toward the side closer to the conveyor 12, and by pulling the slide rail 39 from the slide base 38, the side can be moved closer to the fluidized shelf 11. . As a result, in each zone of the fluidized shelf 11, the temporary placing table 13 can be moved to a position closest to the article storage frontage from which the article is taken out, or to a position near the stop position of the container into which the article is loaded. It

The respective work contents of picking from the fluidized shelf 11 using the above-mentioned bulk picking device 10, loading into the container 15, and inspecting will be described below.

(A) Picking (1) Creation of picking data (FIG. 1, FIG. 2, Table 1) Order data for each delivery destination (store) is first set for each delivery route.
Collect by delivery vehicle (delivery vehicle unit), and then collect order data for multiple delivery vehicles into a picking processing unit (batch unit). Process order data in batches,
Picking data as shown in Table 1 (item storage frontage (product type), number of picked-up items, number of containers of ordered items for each delivery destination (store)) is created.

[0032]

[Table 1]

Further, the planned inventory quantity after picking of the article storage frontage to be picked in each delivery vehicle unit as an inspection unit is calculated. This planned inventory quantity is a planned quantity of the remaining number of articles in one case of the cardboard box cases 16 enrolled in each article storage frontage, which is at the leading edge and is an article unloading source at the time of next picking.

The containers are grouped into groups (compositions) having the maximum number (six in this case) in a single zone, and sequentially transported to each zone. At this time, the containers of a plurality of delivery destinations (stores) are put together to form one organization.
Make sure that the container of one delivery destination (store) does not span two formations.

However, when the number of containers at one delivery destination (store) exceeds the maximum number (6) and is equal to or less than the maximum number of 2 zones (12), the correlation between the future and future at one delivery destination. It composes two knitting machines. At this time, the containers of other delivery destinations are organized differently.

When the number of containers at one delivery destination (store) exceeds the maximum number (6) and also exceeds the maximum number of 2 zones (12), the first to twelfth containers. As described above, as described above, one delivery destination forms two knitting trains that correlate with each other. Then, the thirteenth and subsequent containers are treated as new independent delivery destination containers based on the picking data, and a composition independent of these two compositions is configured.

(2) Picking work (FIGS. 5 to 10) When the picking work is started, the picking control device
Display all picking data of the delivery destination (store) that is first picked in each zone. In FIG. 7 (a), picking data for store A in zone 1 (5 for 2 consecutive stages, 10 for 5 stages, 2 stages), picking data for store B in zone 2 (9 for 1 consecutive stage, 9 (8 in 5 rows of 3 stations, 6 in 1 row of 3 stations)
Is displayed on the picking quantity display 22 of each corresponding article storage front (others are the same) (FIG. 7A).

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

At this time, the operator moves the transverse frame 34 of the temporary storage table 13 along the conveying direction of the conveyor 12, and positions the temporary storage table 13 in the vicinity of the article storage front displayed as the article takeout source. . Further, the worker pulls out the slide rail 39 supporting the temporary placing table 13 from the slide base 38 and positions the temporary placing table 13 in the immediate vicinity of the article storage frontage from which the article is taken out. As a result, the worker can transfer the articles from the article storage front 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 on which the picking quantity display 22 is displayed in the zone, the worker of each zone sequentially places the temporary storage table 13 on each article storage front as described above. While keeping them close to each other, the temporary storage from each article storage front to the temporary storage stand 13 is repeated (Fig. 5 (a)-
(C)).

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

(B) Loading (FIGS. 5 to 10) (1) The containers 15 are collectively conveyed to the picking zone for each of the above-mentioned knitting trains, and arrive at the zone in which the containers 15 should store the articles. Then it can be stopped. Of the containers 15 of the same organization, the input container display 24 corresponding to the container 15 of the delivery destination (store) to which the article is to be input is turned on. In FIG. 7B, the input container indicators 24 of the first and second two containers 15 which are the containers of store A are lit. The worker inserts the article, which has already been temporarily picked up on the temporary placing table 13, into an appropriate container 15 among the containers 15 whose display is turned on. At this time, the worker looks at the contents of the container 15 and puts them together in one container 15 so as not to easily collapse the load, or puts a large item and a small item separately to make them difficult to be damaged. An appropriate container 15 is selected as a reference (FIG. 5 (d)).

At this time, the operator moves the transverse frame 34 of the temporary placing table 13 along the conveying direction of the conveyor 12 and positions the temporary placing table 13 in the vicinity of the container 15 displayed as the article loading destination. Further, the worker pushes the slide rail 39 supporting the temporary placing table 13 into the slide base 38 and positions the temporary placing table 13 in the immediate vicinity of the container 15 which is the above-mentioned article loading destination. This allows
The worker can transfer the articles from the temporary placing table 13 to the container 15 without walking, and the temporary placing table 13 is not fixed in a long range along the conveyor 12, so that the articles are temporarily put in. It is not necessary to carry out over the stand 13, and it is possible to enter the side of the temporary stand 13 and approach the container 15, and as a result, it is possible to easily and quickly insert a predetermined article (FIG. 6B).

(2) Among the containers of the same organization described above, if another delivery destination (store) has an order for an article in the zone, the picking data of the delivery destination (store) is displayed and the delivery is performed. When the input container indicator 24 corresponding to the destination (store) container 15 is turned on (FIG. 7C), the picking data of store B (10 for 2 consecutive 1 stages, 6 for 3 consecutive 2 stages) is displayed. Picking quantity indicator 22 for each frontage
, And the input container indicators 24 of the three third, fourth, and fifth containers 15, which are the containers of store B, are lit. The worker puts the articles on the temporary storage table 13 through the frontages.
Then, the container is put into an appropriate container 15 among the containers 15 indicated above.

Similarly, the picking operation is repeated in other zones (FIG. 7 (d), 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 less than or equal to the maximum number of 2 zones (12) (see FIG. 8 ( In a), the D store has 7 containers), and as described above, two container trains that are correlated with each other are configured as the container trains. The picking quantity display 22 is set for the first container train of the delivery destination (store). , The display operation of the input container display 24 is performed. In FIG. 8A, the preceding container formation of the D store has arrived at the zone, and the remaining one container is on the upstream side. According to the above-mentioned picking data, for store D,
In the zone, 5 from 2 consecutive 1st tiers, 5 from 2 consecutive tiers 12
Pick 8 pieces from 3 rows of 5 pieces. Then, these articles have already been temporarily picked up on the temporary stand 13 in FIG. Then, when the container of the D store arrives at the zone, all the six input container indicators 24 corresponding to the container of the D store are lit up, and the subsequent container presence indicators 26 are lit up in this zone to the upstream side. Also indicates that there is a container 15 for store D. Therefore, the worker puts the article in an appropriate container 15 among 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 2 zones (12) (for example, 15 containers). As described above, as the container organization, the two organizations having the correlation between the first and the twelfth containers are formed, and the containers after the thirteenth container are newly formed as containers 15 for independent delivery destinations. Treat as something. Therefore, for the first to twelfth containers 15, the picking quantity display 22 and the input container display 24 are displayed for the preceding container formation, and as described above, the picking quantity display 22 and the input container display 24 are used in the zones where the first container is loaded. The input containers are displayed by turning on all six input container indicators 24 corresponding to the container 15 and turning on the subsequent container presence indicators 26 in the zone. And for the thirteenth and subsequent containers 15,
It is assumed that the picking quantity display 22 and the input container display 24 perform the display operation as an independent container organization on the picking data, and in the zone where those containers 15 are enrolled, the articles are loaded into these 13th and subsequent containers 15. Turn on the picking quantity indicator 22 of the frontage,
Further, the input container indicators 24 corresponding to the respective containers 15 are turned on to display the input containers. Here, the container for 2 zones is the limit, but not limited to this,
It may be one zone or three zones. When one zone is set, it is not necessary to display the presence of subsequent containers.

The picking quantity display device 2 in each zone
2. The lighting timing of the input container indicator 24 is as follows.

That is, the picked quantity indicator 22 indicates the delivery destination (store) to be picked next after the delivery completion button 25 to the container 15 of the delivery destination (store) to be picked first is pressed. Is displayed. This display disappears when the corresponding extraction completion button 23 is pressed.

Further, the input container indicator 24 indicates that the container 15 to be input in the zone has started in the upstream zone (at this time, the container 15 in the zone has also started, so that the container is not erroneously input. ) Lights up. When the input container indicators 24 are lit for a plurality of containers 15 of the same delivery destination, when any one of the input completion buttons 25 corresponding to them is pressed, all the input container indicators 24 disappear. .

(C) Inspection (FIG. 1, FIG. 2, FIG. 7 to FIG. 11, Table 2) (1) The inspection container 40 is placed in the last container 15 of the containers 15 for one delivery vehicle which is an inspection unit. To follow. The inspection container 40 is made up of one container, and the inspection is performed in the zone where the inspection container 40 arrives. That is, the inspection container 40 is present between the last container 15 of the containers forming the preceding inspection unit and the earliest container 15 of the containers forming the subsequent inspection unit. The inspection space for one zone is opened, and the inspection is performed in the zone where the inspection space arrives.

[0052]

[Table 2]

The inspection container 40 is conveyed not to store the articles but to inform the operator or the picking control device (computer) that the inspection will be performed. The picking control device recognizes in which zone each container organization exists from the output of the load detection photoswitch 28, and thereby can know the arrival of the inspection container 40 in each zone.

(2) In the zone where the inspection container 40 arrives (to be precise, when the inspection container 40 starts in the preceding zone), one of the inspection unit containers 15 corresponding to the inspection container 40 is used. With respect to the article storage front that has supplied the article, the planned quantity already calculated in advance at the picking data creation stage is displayed on the picking quantity display 22 which is also used as the planned quantity display. Figure 8 (c)
Then, the inspection container 40 has arrived at the zone.
At this time, the planned number of zones shown in Table 2 (5 for 2 consecutive 1st stage, 14 for 3 consecutive 2 stages, 18 for 5 consecutive 2 stages, 5 for 3 consecutive 3 stages)
12 pieces in a row) is displayed on the picking quantity display 22.
The worker in charge of the zone displays the planned number of items in stock and the actual number of items in the frontage of the relevant article storage (1 cardboard box case 16
It is checked whether or not the remaining number of articles in the above and the fraction less than one box) match, and if they match, the inspection confirmation button which also serves as the take-out completion button 23 is pressed. When the inspection confirmation button is pressed, the planned stock quantity display of the corresponding article storage front disappears, and the picking control device (computer) recognizes that the stock quantities match. When the display of all the storage fronts of the planned inventory quantity is erased, the inspection in the zone is completed.

In the zone where the article storage frontage is displaying the planned inventory quantity, the above-mentioned picking work lamp 27 is turned off to inform the operator that the inspection is performed.

Further, the inspection container 40 is attached with a label clearly indicating that it is an inspection. A barcode is also printed on this label. Inspection container 4
When 0 passes through all the picking zones, 0 is branched to a route different from the delivery container 15.

(3) As a result of the inspection in (2) above, if the planned inventory quantity and the actual inventory quantity do not match, the operator receives the miss picking list shown in FIG. 11 from the picking control device and makes a mistake. The container 15 of the delivery destination (store) for which the picking type was the input target is searched for, and if the actual storage quantity in the container 15 does not match the ordered quantity, it is corrected (added or reduced).

The mispicking list shown in FIG. 11A has 4 zones, 3 stations and 2 zones when the inspection unit is No. 2.
It shows the mispicking that occurred in the article (mispicking variety) taken out from the article storage frontage of the tier. In this list, among the delivery destinations (stores) corresponding to the second car, the delivery destination (store) for which this mispicking list product was targeted, and the number of orders of the relevant product from that delivery destination (store) , The number of allocated containers, and the loading station number of Car 2 (ST-No with loading) are described.

In this method, it is possible to immediately correct the mispicking because it is known that the mispicking has occurred immediately after the picking. Since picking can be continued during this period, picking work does not have to be interrupted, and there is no possibility of shipping the wrong product.

In this embodiment, one delivery vehicle unit is the inspection unit, but this inspection unit may be the above-mentioned one batch unit or one day unit. FIG. 11B is a mispicking list showing mispicking when the inspection unit is the 15th batch.

The operation of this embodiment will be described below. Every time the last container 15 of the plurality of containers 15 forming the inspection unit passes through each zone, the plurality of containers 15 forming the inspection unit are properly picked for the type and quantity of the zone. Whether or not it will be inspected. That is, it is possible to inspect each picking zone unit during picking. Therefore, when the plurality of containers 15 forming the inspection unit have passed through all zones, the picking to each of the containers 15 is completed, and the inspection is completed at the same time, and it takes almost no inspection time. Further, since the picking operator also performs the inspection in parallel, the inspection operator is not required.

A plurality of containers 15 constituting an inspection unit
As soon as the picking in each picking zone is completed, the inspection can be done, so if you find a picking mistake, pause the picking line and check the type and quantity in the container against the list, etc. Can be fixed immediately.

By checking the stock quantity at the time of inspection only at the article storage frontage where the articles are supplied to any of the plurality of containers 15 constituting the inspection unit, the inspection range is actually set in each picking zone. Therefore, the inspection efficiency can be improved because the inspection is limited to the frontage for storing the articles of the type that should require inspection.

By providing the inspection space by using the inspection container 40, only the inspection is performed in the zone corresponding to the inspection space. Therefore, the worker in charge of this zone is devoted to the inspection work and does not need to perform the picking work at the same time, so that there is no imbalance with the work amount of the worker performing the picking work in other zones. . This means that the productivity of the entire picking line can be improved.

The picking quantity indicator 22 provided at each frontage of the article storage is arranged to switch and display the picking quantity of the article to be taken out into each container 15 and the planned stock quantity at the time of inspection, thereby constructing the picking system. Can be simplified.

[0066]

As described above, according to the present invention, it is possible to improve picking productivity when inspecting whether or not the type and quantity of picked articles match the order contents.
