However, the above-mentioned conventional technology had the following problems.

That is, the warehouse system described in Japanese Patent Application Laid-Open No. 49-112370 is designed so that articles are sorted within the warehouse system and the sorted and completed pallet cargo (unit load) is immediately taken out of the warehouse. Since it is not possible to start sorting the goods until the delivery vehicle arrives, and it takes a long time to arrange the goods, there is a large amount of idle time from the arrival of the delivery vehicle until the time when the goods have been sorted and can depart.

Furthermore, the stunker crane described in Japanese Patent Application Laid-Open No. 188204/1988 picks desired quantities of desired types of articles and dispatches them by type. It is not mentioned and there is no suggestion whatsoever.

Therefore, an object of the present invention is to immediately dispatch a unit load consisting of a plurality of types of articles, which are formed by sorting the necessary number of articles for each type, from the articles stored and sorted by type, when a delivery vehicle or the like arrives. An object of the present invention is to provide a method for arranging articles in a manner that allows for the sorting of goods.

(Means for Solving the Problems) The present invention is an article sorting method for assembling a plurality of types of articles, in which the necessary number of articles for each type are sorted and stored. By providing a method for assembling goods, which is characterized by forming a unit load consisting of a plurality of types of articles, temporarily storing the unit load in a storage facility, and then taking out the unit load from the storage facility. The purpose has been achieved.

Reference numeral 107 is a conveyor line for stowage, which transports the above-mentioned discharged articles to a stowage location. 108 is stowage. 109 is banding, and the unit load (pallet loaded with articles) is banded to prevent the load from collapsing.

Reference numeral 110 indicates warehousing, and the banded unit load is divided into two pallets for each direction of transportation and is then warehousing. 111 is a storage facility (fixed tank), where the received pallets are stored on fixed shelves (ranks) by a 2-pallet handling stacker crane (tuple fork stacker crane) until a delivery vehicle, etc. (transport truck) arrives. . 11
2 is unloading, and when unloading is set, it is unloaded from the rank by a double fork stacker crane. 113 is truck loading, in which the discharged pallet is loaded onto a transport truck by a truck loader. In addition, if there is an urgent need to load onto a transport truck, a double fork stacker crane can be used directly from the storage area 110 to the storage area 112.
There is a short path mode 111' in which the cargo is loaded onto a truck.

A plurality of pallets (seven in the embodiment) are loaded on the transport truck and transported to each terminal. 114 is transportation to the terminal. 115 is a transshipment operation in which a unit load pallet that has been transported by a transport truck at the terminal is transferred to a 2-ton delivery vehicle using a forklift along with a slint tube sheet. 116° is delivery to retail stores, etc.

Here, loading is carried out from the storage facility 100 to the conveyor line 10.
7. The process from warehousing 110 to truck loading 113 is automatically controlled by a computer.

Figure 2 shows this computer control system,
General management CPU (central processing unit) 201, logistics CPU
202, a control CPU 203, a sorting system 204, and a warehousing/receiving system 205.

The overall management CPU 201 performs overall management of the entire logistics system, and for example, creates a schedule for the delivery order of goods based on order data, etc.
Send to. The logistics CPU 202 determines the group for sorting the article according to the delivery order schedule of the article, creates data for branch sorting and batch picking data, and performs control? 711 Output to CPU 203. Control CPU2
03 creates necessary control instructions based on this branch sorting data and batch picking data, and outputs the sorting to the system 204. The control device of the sorting system 204 is composed of a sequencer, and performs necessary controls such as merging control, branching control, and dispensing control.

Further, the control CPU 203 outputs transportation direction data to the input/output H system 205. The control device of the warehousing/unloading system 205 is comprised of a sequencer, and performs necessary controls such as warehousing control, warehousing control, and loading control.

Next, referring to FIGS. 3 and 4 (a), (b), (a') and (bo), an embodiment of the sorting process of the article arranging method of the present invention will be specifically explained .

In FIGS. 4(a), (b), (a') and (b'),
301 is a pallet for loading goods; 302 is a loader; 3
03 is the sorting line, and 304 is the branching line. Then, sorting is done by line 303 and branch line 30.
4 are provided in two stages, upper and lower, and in FIG. 4(b), 30
3-1 indicates the line for loading and sorting inside, and 303-2 indicates the line for sorting inside. In these figures, the articles are represented by small squares corresponding to their respective sizes.

Now, a case will be described in which goods are divided into five parts on the pallet 301 to form a single load. In this case, the logistics CPU 202 creates the necessary data according to the flow sheet shown in FIG.

First, in step (Sl), the pallet volume (volume of pallet packaging) 301a is divided into a plurality of parts. Figure 4 (a
) (b) In the examples of (a') and (bo), the bullet volume 301a is divided into five parts such as ■, ■, ■, ■, and ■. In this case, since the articles loaded on the pallet 301 are unloaded from the rear of the loading platform of the 2-ton delivery vehicle 115 shown in FIG. 1, the pallet 301 is divided into five parts in the longitudinal direction. In this case, the planar dimensions (length or width) of the article
Since it is more stable during delivery if larger items are stacked at the bottom, the number of divisions is determined by dividing the valent length by the length of the relatively larger item (an integer). In this case, the traveling direction of the pallet 301 and the longitudinal direction of the articles are made to coincide, but this is not the case.

Next, in step (S2), the length of the sort is determined.

The length of sorting is determined so that the number of articles that can be stored in one divided section of the baren 301 can be stored on one sorting tube 303. Therefore, Fig. 4(a) (
b) As shown in (a') and (bo), the articles stored in the line 303 are stacked on the divided section of the pallet 301. In the following question, the articles stored in the line 303 for sorting ■, ■, ■, and ■ are stacked in the divided sections ■, ■, ■, and ■ of the valent 301, respectively.

Then, in step (S3), the branch sorter creates data.

Assume now that orders for delivery of goods have been given to 15 stores as shown in the table.

(Imitation υ) In this table, a to g represent product type classifications, and as shown in FIGS. 4(a) and (g), the products are arranged in descending order of length. As can be seen from the table, the order contents vary greatly depending on the product type and are not uniform. First, the shipping destinations are rearranged in the order of stowage as described above, and the articles are arranged in order of length as described above. Next, based on this table, calculate the multiplication value for each item from the first wide item by multiplying its quantity by its length, and then calculate the length by adding this multiplication value sequentially to the right for each item. Find the added value.

When the added value of this length almost reaches the length given when the total amount of items is divided into 5 equal parts, the data is divided, and the items up to this point are sorted as a group, and each item is sorted individually. The line number is determined to be ■, and the branch sorting creates data so that the sorting of ■ is branched and stored on the line. In the table above, the total amount of goods addressed to 15 stores is 145
The pieces are sorted into five parts taking into account the line length, pallet volume 301a, delivery efficiency, etc. In other words, ■ divided into 5 parts is 21 pieces for store 1 and 21 pieces for store 2.
There are 6 items addressed to store 3 and 2 items addressed to store 3, for a total of 29 items. Similarly, ■ is divided into 5 items: 1 item addressed to store 3, 21 items addressed to store 4, and 5 items addressed to store 5, for a total of 27 items. The ■ that was divided into 5 parts is 6 pieces for store 5, 5 pieces for store 6, 13 pieces for store 7, and 7 pieces for store 8, a total of 3 pieces.
1 piece, ■ divided into 5 pieces is 5 pieces for store 8, 5 pieces for store 9,
A total of 30 items, 12 items addressed to store 10 and 8 items addressed to store 11, and 5 items divided into 5 items are 2 items addressed to store 1I, 7 items addressed to store 12, 9 items addressed to store 13, 7 items addressed to store 14, and 15 items. There were three recipients, totaling 28 pieces, each containing about 30 pieces.

The orders shown in the table above are processed by the general management CPU 201.
The number of shipping destinations that can be loaded for each valent is determined by
The order of delivery routes is also determined.

Furthermore, batch picking data is created in step (S4).

As mentioned above, each pallet is divided into multiple pallets, separated by pallet unit (transport unit), and the sorting is completed on almost all lines 303, and the total of all goods is The total amount of kings. In the table above, there are a total of 3000 pieces. Batch pinking data is created by summing up all the pallets for each product type, and in this case, bumping the items in order of increasing length.

As described above, articles are loaded on the pallet 301 over the entire pallet and at approximately the same height, as an example of which is schematically shown in FIG.

The overall management CPU 201 calculates multiple (in rare cases, a single) delivery destination for each valentine, and after determining the order of delivery destinations, the logistics CPU 202 performs the above calculation process to create batch picking data. Since batch picking is performed based on the above, multiple pallets can be picked at once, which is more efficient than single pallet picking.

In addition, instead of sorting by store, the capacity of the pallet is divided into multiple parts, the number of items is divided, the capacity of the pallet and the sorting is done within the limit of the line length, and the sorting is stored on the line, which saves space. Good efficiency. In the order example shown in the table above, as shown in Figures 4(a) and (b), the products are ordered in descending order of length: a, b, c, d,
It can be divided into e, ``and g.

In addition, the goods are sorted by line 303. Items marked with ■ are taken out from line 303 and stacked one after another on the divided sections marked with ■ on the pallet 301, so that the items addressed to store 3 are divided into the items addressed to store 1 and store 2 in the table above. Although the first batches are mixed up by type, if the delivery person (driver) delivers to these delivery destinations in the order of store 3, store 2, and store l, the delivery person will arrive at the delivery destination and finish the delivery. When viewed from the rear of the vehicle's loading platform, the corresponding article is present in the divided portion that almost faces the vehicle. In other words, items to be delivered later do not come to the front or items to be delivered first go to the back, and the goods can be selected and unloaded from the divisions facing each other. The same effect as branching and loading can be obtained. This allows the deliverer to carry out the unloading work more efficiently6.Furthermore, since the goods are loaded on the entire pallet at approximately the same height, there is no chance of the goods being shifted during delivery.
It can be delivered safely.

The articles sorted and stacked in the balent by the above method are banded and stored in the ranks.

Next, with reference to FIGS. 6 and 2, an embodiment of the loading/unloading mode for temporary storage in the article arranging method of the present invention will be specifically described.

In Figure 6, 301 and 302 are shown in Figure 4 (a'')
Also shown in (b'') are a pallet and a loader for loading goods. Also, 401 is an empty pallet magazine, 402
403 is a conveyor conveyor conveying the pallet 301 sent out from the empty pallet magazine 401 to the article loading department;
The goods are loaded on the pallet 301 on the conveyor 402.
This is a revolving trolley that receives pallets 1-301 loaded with goods and sends them to the next process.

Pallet 301 with completed loading (unit load)
is rotated by a rotating cart 403 and sent to a conveyor 404. Pallet 301 is conveyor 4
04, and sequentially sent to conveyors 405 and 406. Pallet 301 is conveyor 4
06, the traverser 501 moves the pallet 301 from the transport conveyor 406 to a predetermined warehousing loading station 60 according to instructions from the warehousing/unloading system 205.
1 in 1 hyperactive.

When the pallet 301 transferred to the loading station 601 is loaded with goods for transportation to Maebashi, the same pallet for transportation to Maebashi is loaded into the rack (storage equipment) 801 at the loading loading station next door. After being loaded onto station 602, two barrels I are loaded onto station 602 by stanker crane 701.
-Handled at the same time. Control CPU20
When the unloading setting is performed in step 3, the stacker crane 701 moves the corresponding pallet to the unloading loading station 901/9.
02 or 903/904, 2 valents will be delivered at the same time. The pallets 301 delivered to the delivery loading station are transported one by one to a predetermined track loader zoi by the traverser 1001. In the embodiment, since seven vallets can be loaded on the transport truck 1201, the above-described unloading operation is repeated until the maximum valets are aligned on the trunk loader 1101.

When the pallets 301 are arranged on the truck loader 1101 and the transportation truck 1201 lands on the floor, the pallets are loaded into the transportation trunk 1201 by the trunk loader 1101.

As mentioned above, pallets loaded with products for the same one-way transportation are placed at a pair of warehousing loading stations 601 and 60.
By collecting the two pallets on the rack 801 using the stanker crane 701 and storing them temporarily, it is possible to unload and arrange the pallets at the same time or before the arrival of the transport trunk. Since two pallets can be delivered at the same time, delivery and stock arrangement efficiency is high.

Next, an embodiment of an article arranging apparatus to which the article arranging method of the present invention as described above is applied will be described with reference to the drawings. The explanation will be made in accordance with the logistics system flow shown in FIG.

That is, the above-mentioned valet cargo is transported to the vicinity of the above-mentioned automated warehouse by means of transportation such as a trunk, and is then supplied to the above-mentioned warehousing line by a forklift or the like, and then temporarily stored in the automated warehouse via the above-mentioned warehousing line. The palletized cargo stored in the automated warehouse is taken out via the unloading line and separated into individual articles by the area-by-area gripping device, and the articles separated into areas are supplied to the case flow rack by the feeder. Each type is stored in the case flow rank. Further, the articles stored in the case flow rack are picked out in the required number by the pinking device based on the picking data, and are supplied to the picking line 101.

In addition, from the storage facility 100 to the pinking line 10
The above-mentioned article can also be fed directly to the above-mentioned case flow rank without passing the above-mentioned article separated into planes by the above-mentioned plane unit gripping device into the above-mentioned case flow rank.

Further, the picking line 101 is connected to the storage equipment 1.
The main component is a conveyance line that supplies the articles supplied by the pinking device No. 00 to the storage line 102.

The storage line 102 shown in FIG. 7 is constructed based on the punch picking data.
It has three sets of storage containers IA, IB, and tC for storing the above-mentioned articles supplied from 1.

A converging conveyance line 103 that collectively sends out a predetermined amount of these articles is connected to each of the storage conveyors LA, IB,

It is composed of merging and conveying conveyor belts 3A and 3B arranged substantially perpendicular to this merging and discharging conveyor. As shown in FIGS. 7 and 8(b), the merging conveyor 3B passes through a floor pitch (FP) provided on the floor and is arranged at an angle, and is connected to the switching conveyor 4 provided downstairs. There is no way to send the goods.

As shown in FIG. 8, the switching conveyor 4 moves up and down at its left end in this figure, and transfers articles to either the conveyor 5 or 15 installed above and below. In FIG. 8(a), the conveyors installed in the upper and lower layers are shown in parentheses near the reference numeral of the related upper layer, since the lower layer overlaps the upper layer and is not shown in FIG.

The articles sent on the conveyors 5 and 15 are placed at regular intervals on the index feeders 6 and 16. The branching line 104 is operated by branching conveyors 7 and 17 equipped with branching devices, and the articles are sorted into a large number of pull-in conveyors 8 and 18 arranged approximately perpendicular to the branching conveyors 7 and 17 based on group data. It is for sorting. As shown in FIG. 8(a), the sorting line 105 is composed of inclined roller conveyors 9 and 19, and the articles sent by the retracting conveyors 8 and 18 are affected by the gravitational force of the articles due to the inclination. The products are self-propelled, sorted, and stored on the roller conveyors 9 and 19.

The above dispensing line 106 is 1, dispensing devices 10 and 2
0, and when the control CPU 203 sets dispensing on either the upper or lower side, the stopper means is released for each line on a pallet basis and dispensing is performed (see FIGS. 10(a) and (b)).

The articles discharged in this manner are transported to the loading port of the pallet by the conveyor line 1071 (conveyors 11 and 21), and the loading is carried out by the conveyor 160 (22) and the stopper 13 (23).
loader 302). At this time, as shown in FIG. 8 (6), a switching conveyor 150 is placed between the upper and lower layer transport conveyors 14 and 24 and the stacking conveyor 160.
When an article is delivered from the upper transport conveyor 11, the left end of the switching conveyor 150 rises to the position where it is connected to the transport conveyor 14, and when an article is delivered from the lower transport conveyor 21, the left end of the switching conveyor 150 moves up. moves down to a position where it is connected to the conveyor 24 (indicated by a broken line). In this way, the articles are loaded onto the balent 301 via the conveyor 160.

Next, the sorting or moving operations of articles on each line will be explained.

Figures 9(a) and (b) show branch conveyor 7 (17)

Figure 1 shows a transfer 12 (indicated by a - dotted chain line) that is placed on a conveyor conhair 11 (21) and sent in the direction of the arrow g (indicated by a - dotted chain line), and transferred to a conveyor conhair 14 (24), not shown, arranged in the direction of the arrow. 22) and a perspective view showing the operation of the stopper 13 (23). When the article is not transferred, the transfer cylinder 12B and the stopper cylinder 13B do not operate, so the large number of wheels 12D and the stopper plate 13A provided on the frame 12C
The upper end is located at a lower position than the upper surface of the drive roller 12A. Therefore, the article passing over this travels in the direction of arrow g. When a signal for performing a transfer operation is input, the transfer cylinder 12B and the stopper cylinder 13B operate in the directions of arrows j and k, respectively, and each wheel 1
Since the 2D and stopper plate 13A are raised to the position indicated by the broken line, the article is transferred in the direction of the arrow.

In FIG. 8(a), overflow lines 25 and 35 shown on the left are for storing articles that cannot be branched because there is no branching data.

In addition, the operation control of each part in the above description is performed via the logistics CPU 202, the control CPU 203, and the sorting system 204 shown in FIG.

FIG. 6 is a schematic plan view illustrating the article stowage section provided below the sorting line 105 and the loading and unloading mode for temporary storage of articles. The articles are sorted out from the line 105 and then loaded via the container 160 to the loader 30.
2, they are stacked manually onto the pallet 301.

The loader 302 can be expanded and contracted in the transport direction of the articles in order to improve loading efficiency. The loaded pallet 301 (unit load) is rotated by a rotating cart 403 and sent to a conveyor container 404. When the operator finishes sending the pallet 301 to the conveyor container 404, the operator returns the rotating cart 403 to the origin (indicated by a solid line) and presses the empty pallet te port (not shown) to remove the empty pallet from the empty pallet magazine 401. are supplied to the rotating cart 403 via the conveyor 402, and the goods are loaded onto the next pallet. On the other hand, the pallets sent onto the transport conveyor 404 are banded using nets, horizontal or vertical restraining bands, etc. to prevent the cargo from collapsing during transportation. When the banding is completed, the operator presses a banding completion button (not shown) and conveys the pallet 301 to the conveyor 405. If there is no preceding balent 301 on the conveyor conveyor 406, the pallet conveyed to the conveyor 405 301 is automatically conveyed to the conveyor 406. When the pallet 301 arrives at the conveyor conveyor 406, the warehousing and unloading system 205
According to instructions from , the traverser 501 moves to a predetermined position, picks up the pallet 301 from the pallet transport conveyor 406 , and transfers it to a predetermined warehousing loading station 60 .
Supply to 1. As described above, in order to increase the capacity for loading and unloading pallets for temporary storage, pallets to be transported to the same side are aligned at the adjacent loading station 602 before being loaded. In the embodiment, there are four loading stations and four pairs of loading stations.For example, a pallet for transport in the A direction is loaded at 403 in the part (2), and the traverser 501 loads the pallet for transport in the A direction. is supplied to 601 of the receiving loading station (1), and the cargo for direction transportation is also loaded at 40 of section ①.
3, the traverser 501 supplies the pallet for transport in that direction to 602 of the 1 m loading station (1), and carries out the bearing of the pallet for transport in the same direction. For same-sided transportation pallets, same loading is part 40.
It is desirable to stack the goods at 3 and supply them to the nearby loading/unloading station, considering the capacity of the traverser 501, etc. In principle, the sorting method for sorting the goods to the line 105 corresponds to the container 160 for each stowage. It is preferable that articles transported in the same direction are sorted for each sorting window 105.

When the control CPU 203 performs the unloading setting (transport direction number setting), the stacker crane 701 moves the corresponding parent to the unloading station 901, 902 or 90.
Issued on 3/904. Valent for which the unloading setting has been made before warehousing is carried out at the warehousing loading station 601.
602, the stacker crane 701 directly moves the loading stations 901 and 902.
Alternatively, the vehicle is delivered to 903/904 (short path mode).
