As shown in FIG. 1, the bulk picking apparatus 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, a fluidized shelf 11 and a 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 a plurality of inclined conveyors 21 for storing articles (commodities) to be picked 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 (item 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.

At the stop position of each container 15 on the roller conveyor 12, an input container indicator 24 for displaying that the container 15 stopped at the stop position should input an article, and a computer for notifying 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 following 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.

Specifically, the roller conveyor 12 includes a driving force transmitting member for transmitting the 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 is for temporarily placing 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

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, 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.

In the following, the operations of picking from the fluidized shelf 11 using the above-mentioned bulk picking device 10, loading into the container 15, and inspection are 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.

[0032]

[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 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 operator 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 frontages 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) initially 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 of the knittings, sequentially conveyed to a picking zone, and arrive at a zone where articles should be stored in the containers 15 in the knittings. 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) If there is an order for an article in the zone at 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. 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.

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 the delivery destination (store) to be picked next after the loading completion button 25 to the container 15 of the delivery destination (store) to be picked in advance 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) Inspection container 40 is attached to the last container 15 of one delivery vehicle container 15 serving 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.

[0052]

[Table 2]

The inspection container 40 is transported not for storing articles but for notifying an operator or a picking control device (computer) of performing inspection. 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 exact, 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 notify the operator that the inspection is performed.

The inspection container 40 is provided with 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), if the planned stock quantity and the actual stock quantity do not match, the operator 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 known that the picking has occurred immediately 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, one delivery vehicle is used as the inspection unit. However, the inspection unit may be used in the above-described 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 this embodiment will be described. Each time the last container 15 of the plurality of containers 15 constituting the inspection unit passes through each zone, the picking of the plurality of containers 15 constituting the inspection unit is performed correctly for the type and quantity of the zone. Inspection is performed to determine whether or not it has been completed. That is, the inspection can be performed in each picking zone unit during the picking. Therefore, when the plurality of containers 15 constituting the inspection unit have passed through all the zones, the picking to each of the containers 15 is completed, and the inspection is completed at the same time, and the inspection time is hardly taken. Further, since the picking operator also performs the inspection in parallel, there is no need for the inspection operator.

A plurality of containers 15 constituting an inspection unit
After picking in each picking zone is completed, inspection can be performed immediately, so if a picking mistake is found, the picking line is temporarily stopped and the type and quantity in the container are checked against the list etc. Can be corrected immediately.

By checking the stock quantity at the time of inspection only at the article storage frontage where the articles have been supplied to any of the plurality of containers 15 constituting the inspection unit, the inspection range can be set within each picking zone. In this way, the inspection is limited to only the article storage frontage of the kind that needs to be inspected, and the inspection efficiency can be improved.

By providing the inspection space using the inspection container 40, the inspection is only performed in the zone corresponding to the inspection space. Therefore, since the worker in charge of this zone concentrates on the inspection work and does not need to perform the picking work at the same time, there is no imbalance between the work amount of the worker during the picking work in another zone. . This means that the productivity of the entire picking line can be improved.

The picking quantity display 22 provided at each article storage frontage displays the picking quantity of articles to be taken out to each container 15 and the planned stock quantity at the time of inspection by switching and displaying the picking system. Can be simplified.

[0066]

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