[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a system for picking from a pallet of mixed goods taken out from an automated warehouse, etc., and a system for placing dogs on this mixed pallet. .

In this invention, "picking" refers to taking out cargo to be shipped from a mixed pallet that has been delivered from an automated warehouse, or loading cargo onto a pallet to form a mixed pallet for storage in an automated warehouse. , refers to either one of the following. However, in the Detailed Description of the Invention column, the two are distinguished.

In this invention, a pallet includes a bucket.

[Conventional technology]

In warehouses such as multi-level warehouses using stacker cranes and rotating shelves, goods are stored on pallets.

The storage status of grapes on pallets is 1 per pallet.
There are cases in which various types of cargo are loaded, and cases in which multiple loads are loaded on one pallet. The latter is called a mixed pallet. In the mixed pallet system, the automated warehouse computer stores the type and quantity of cargo for each pallet. (Unexamined Japanese Patent Publication No. 63-25
(Japanese Patent Application Laid-open No. 8305, Japanese Patent Application Laid-Open No. 63-208409, Japanese Patent Application Laid-Open No. 63-97505) In the mixed pallet system, when a delivery request is made, the corresponding mixed pallet is carried out to the delivery exit. Then, exit the warehouse (
A worker at the picking workshop picks the parts from the mixed pallet based on the name and quantity of the Pizza King parts (outgoing parts) based on the picking instructions or the like. When the picking is completed, the pallet is returned to the warehouse entrance.

On the other hand, regarding the method of packing cargo for this mixed pallet,
A pallet with at least one empty storage area is conveyed to the loading area by a conveyor line.

The worker loads the empty storage area. If there are multiple empty storage areas, place the load in one of them. The computer stores the pallet, the type and number of loads.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the picker must be familiar with the parts to be picked and their names, and must also search for where the parts are on the pallet, which requires time and effort. It was time consuming.

An object of the present invention is to improve the efficiency of picking work without requiring a picker to memorize picking parts.

In addition, an object of the present invention is to
The purpose is to ensure that a load can be placed in a predetermined storage area without fail.

[Means to solve the problem]

The purpose of the above-mentioned pibbing is to distinguish the loads on the pallet (bucket) by type in order to match the name of the picked part with the actual item, memorize each storage area on a computer, and then use the computer at the picking location. This is achieved by visually indicating the storage area of the item to be picked on the pallet.

The purpose for loading is achieved by visually indicating the storage area for loading.

[For production]

In either case, the target storage area is visually indicated. Therefore, it is possible to pick and place loads without fail.

[Example] Hereinafter, an example of the present invention in the case of pibbing will be described with reference to FIGS. 1 to 4.

Figure 4 shows the pipping area, and in front of worker M is a conveyor 10 carrying pallets taken out from an automated warehouse.
and is stopped by the conveyor 11. here,
The picked cargo is placed in a packet 16 on a loading platform 15 for shipping. The bucket 16 on the loading platform 15 is carried out by a forklift or the like. CR is placed in an easily visible position near worker M.
There is a display device side and a command device 31 consisting of T and the like. The display device side may be installed at a position facing the worker M via the conveyor 11.

In FIG. 1, above the conveyor 11 are four projectors 21a, 21b, 21c, 21d.
There are irradiators equipped with The floodlights 21 a to 21 d are located on the conveyor 11 .

Visible light can be projected onto the 20 loads from above.

A computer (not shown) drives the irradiator unit and the display unit based on commands from the command unit 31 and the like.

The pallet ω is partitioned into four parts by a partition plate 41, and a load is placed on each area. Even if there is no partition plate 41, the load is placed on these four areas.

As shown in FIG. 3, there are four patterns for loading the load onto the beginning of the pallet, based on the four areas A, B, C, and D. Pattern 1 is a case where all the loads are of the same type. Patterns 2 and 3 are cases where there are two types of loads, and the orientations of the loads are different. Pattern 4 is a case where the load has four types of IMM. Pattern 4 also includes a case where there are three types of loads.

Of course, depending on the size of the load (occupied area),
D is determined.

The computer memorizes the type of load and its position (storage area) A, B, C, and D for each pallet.

The irradiators □ are four projectors 21a and 21b corresponding to the four areas, as shown in pattern 4 in FIG. 3.

21c and 21d. The projectors 21 a to 21 d are arranged corresponding to the respective areas A to D, and irradiate the pallet with visible light. For example, the projector 21a is in area A.
The other areas B, C, and D are not irradiated.

The picking target will be explained with reference to FIG.

When a delivery request is made, the computer takes out the corresponding pallet from the automated warehouse and transports it to the picking work area by a conveyor line. Conveyor 11 in front of the worker at the piping area
When the package arrives, the conveyance of the pallet cutter is stopped and the process shown in FIG. 2 is executed. In FIG. 2, the computer manages tracking data, so it can be seen which pallets have arrived.

Step 81'1: The computer outputs the position (A to D) of the part to be picked. To notify the position corresponding to one type of parts even if there are a plurality of items to be picked on one pallet. Based on this, the illuminator side adjusts the emitter 2 at the corresponding position.
1a to 21d to project light. In pattern 1, all the projectors 21 a to 21 d project light, in patterns 2 and 3, two projectors project light, and in pattern 4, one projector projects light.

Further, the calculator displays the number of parts to be pizza-sized on the display screen. In addition, it is preferable to display the position (area) and part name of the target part. In addition, it is also possible to display related information such as the destination of the picked parts, related parts, and how to store the parts.

The worker M pizzazzles the parts in the area illuminated by the projectors 21a to 21d. The number of Pizza King is the number displayed on the display side.

Step 813 After performing the number of pizza kings displayed on the display, the operator M presses a button on the command device 31 to input the end of pizza king.

Step 815 If there are any more parts to be pizza-sized on this pallet, the computer returns to step 811 and outputs the position, number, etc. of the next part to the irradiator □□□ and the display. The same applies below.

On the other hand, if there are no parts to be pizza king, conveyor 11
etc. to transport pallets.

In the above embodiment, the number of bib kings can also be specified in the instruction sheet. However, if the number of parts picked last time is displayed on the screen, the number of parts picked last time disappears, so there are fewer mistakes. Furthermore, since the number of parts is displayed in a large size, recognition can be made easily and reliably. Further, it is possible to eliminate the need for checking instructions.

Further, in the above embodiment, the storage area to be picked is irradiated, but other storage areas may be irradiated to indicate the storage area to be picked.

When the pallet ω is divided in a cross shape as in the above embodiment, it is easy for the operator to make a pizza from the two areas on the M side, but it is necessary to extend the hand to make a pizza from the two areas on the back side. , it's easy to work.

The embodiments shown in FIGS. 5 and 6 were made in view of this point. The conveyor 11 in front of the worker M is placed on a turntable. The turntable n can be stopped every 90 degrees. The computer can recognize the positional relationship between each area A to D of the pallet rack on the conveyor 11 and the worker M. Two areas are located on the operator M side of the pallet phrase, but the area where operator M pizzas is only the area on the left side of the front in the figure.

If necessary, simple cover markings are provided to prevent access to other areas. For example, this cover mark is made entirely of mesh and is placed above the other three areas except for the Pizza King area on the left side of the front. A cover 50a is also located in front of the area on the left side of the viewer. This is because, for example, parts are placed in each area, and pizza kinging can be performed each time a part of each area is located in the pizza king area.

To facilitate rotation of the pallet sum, turntable 1
2 is placed on the lifter 13.

The operation will be explained with reference to FIG.

Step 821 When the parebut first arrives on the conveyor 11, the computer instructs the turntable ratio so that the part to be picked is located in the pizza king area on the front left side. This causes the turntable ratio to rotate the pallet cutter into position. Of course, the conveyor 11 is raised and rotated by the lifter 13.

If there is no need to rotate, the process moves to the next step S23.

Step 823: When the target part stops in the picking area, one light projector 21f provided above this area is turned on. Also,
Display the number of Pizza King on the display side.

Since this light projector 21f indicates that picking is possible, it is not necessary to project light onto the parts, and a lamp 21g that emits weak light may be provided on the cover =□□□. Conversely, the light may be turned off when Pizza King is available.

The following steps are similar to the embodiment of FIG.

In the embodiment shown in FIG. 5, if the size of the part occupies two areas and the part cannot be pizza-picked from only the picking area on the left side of the front, the cover on the right side of the front is excluded. Furthermore, remove the upper cover of the area on the right side. In addition, in the case of parts occupying three or more areas, the cover itself is excluded.

According to this embodiment, Pizza King can be done from the front, so
This makes it easy to pick. In addition, even if there is no cover mark, the picking area can be fixed through prior education and experience, so pizza king defects can be prevented.

In the above embodiment, the turntable ratio is stopped every 90 degrees, but it may be stopped every 180 degrees.

In this case, a floodlight or a lamp is provided in each of the two front storage areas or above the cover to indicate which storage area the pizza king is to be started from.

The embodiments shown in FIGS. 7 and 8 will be described.

In FIG. 7, when the worker M faces the conveyor 11 side, the worker M is facing the worker M via the conveyor 11.
A display device 3f)a is provided facing toward. In addition to the number N of pizza kings, the display 30a also shows the four storage areas P of the pallet.
is displayed on the screen as shown.

Then, the pizza king target area is displayed in a distinguishable color (indicated by hatching in the drawing). The command device 31 is placed near the worker M. The display device side may be a television, or may be one in which a large number of light emitters are lined up.

The operation will be explained with reference to the flowchart in FIG.

Steppi 831 When the pallet 40 stops on the conveyor 11, the display 30
The picking area and the number of pizza kings are output to a.

The display device displays the picking area and the number of pizza kings on the screen.

The following steps are the same as the embodiment of FIG.

Next, an example of configuring this mixed pallet 1-40 will be described. In FIGS. 1 and 4, each device may be read as follows. 16 is a packet which is a container for loading goods onto a pallet.

There are a number of packets 16 corresponding to several types of loads as necessary. IO is a conveyor line whose downstream side is connected to the storage entrance of the automated warehouse. The display side displays the number of loads in the packet 16 to be placed on the pallet 40.

The type of load on the display will also be displayed if necessary. 31 is a display for inputting the end r of this reloading.

The irradiator side emits light onto the storage area where the load is placed.

As described above, the operation of each device is as shown in FIG. However, "Pizza King" should be read as "consolidated loading on pallets."

The computer determines the content of consolidation in advance and executes it. In addition to being applied to new pallets, it can also be used to replenish pallets that have empty storage space due to Pizza King.

Therefore, the pipping method and apparatus in each of the embodiments shown in FIGS. 5 to 8 can also be used as a method and apparatus for mixing loads on pallets. Further, this mixed loading includes pattern 1.

〔Effect of the invention〕

According to the present invention, picking and consolidation can be carried out quickly and accurately because the work can be done visually without relying on the skilled judgment of the pizza king or consolidation operator.
