[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic picking warehouse.
[0002]
[Prior art]
Conventionally, as shown in the JIS Z 0105 transport packaging series dimensions, the pallet for loading a case containing a plurality of articles is mainly a wide pallet having a length of 1100 mm to 1200 mm and a width of 1100 mm to 1000 mm. Yes. For this reason, in the conventional automatic warehouse, all of the shelf size of the storage shelf and the conveyor size of the pallet entry / exit line are set to a wide size that can accept the wide pallet.
[0003]
[Problems to be solved by the invention]
By diversifying goods and direct shipping (delivering to direct distribution center of retailers, omitting intermediate inventory bases such as wholesalers)RorderButSmall grainis doing.
thisWhereasIf a pallet with a low number of loading stages is placed in a high load shelf of an automatic warehouse, storage efficiency will decrease, and if priority is given to warehousing on a low load shelf in an automatic warehouse, pallet loading (stage number) efficiency will not improve, so automatic The warehouse space cannot be used effectively, and as a result, the delivery capacity cannot be improved.
on the other hand,There are the following problems in storage and handling in an automatic warehouse based on a conventional wide pallet.
[0004]
(1) The pallet load of a wide pallet makes a large and heavy packaging of the same type of goods, makes it difficult to store a wide variety of pallets in a certain space, and requires a large space for installing an automatic warehouse.
[0005]
(2) Automatic warehouses are filled with wide storage shelves and conveyor lines, making it impossible to increase the number of cranes installed. For this reason, the number of delivery pallets per hour (shipping ability) cannot be increased, the shipping speed cannot be increased, and it is difficult to cope with the time specification for delivery to the delivery destination.
[0006]
(3) If picking is performed directly from the wide pallet in case units / separate units, the picking workability is poor because the pallet depth cannot be reached as viewed from the take-out side. In order to solve this problem, it is necessary to provide a depalletizing device on the shipping line in the automatic warehouse, depalletize the case on the pallet and supply it to the picking zone, and the configuration of the automatic warehouse becomes complicated.

The picking automatic warehouse 10 in FIG. 1 loads a case 1 containing a plurality of articles of the same type on a narrow pallet 11 of a narrow width size, and carries the narrow pallet 11 carried in from a warehousing line 31 in a multi-stage multi-row (main book). In the embodiment, it is stored in one of the storage shelves 21 of the narrow pallet storage 20 provided with a plurality of storage shelves 21 in six rows.
[0028]
As shown in FIG. 2 (A), the narrow pallet 11 has a length × width of a narrow width such as 1320 mm × 550 mm, 1100 mm × 660 mm (in the range of 1100 mm to 1320 mm in length, in the range of 650 mm to 550 mm in width) In addition to case 1 for storing articles in units of cases, the same kind of articles can be loaded together with bulk transport containers 2 such as trays, containers, and opened cases for storing articles in units of individual pieces (single unit). Yes. The wide pallet 12 corresponding to the narrow pallet 11 has a length × width of, for example, 1100 mm × 1100 mm, as shown in FIG. 2B. The pallet area of the narrow pallet 11 is about 60% of that of the wide pallet 12.
[0029]
The storage 20 has a stacker crane 22 disposed between two opposing storage shelves 21 along the shelf front of each storage shelf 21.
[0030]
The picking automatic warehouse 10 has an unloading line 32 for unloading the narrow pallet 11 unloaded from the storage shelf 21 of the storage 20, a loading / unloading line 33 connected to the unloading line 32, and a re-entry line 34 connected to the loading / unloading conveying line 33. And a transport conveyor 35 (transport means) for transporting the narrow pallet 11 across each line.
[0031]
A bar code reader 36 is installed at the entrance from the output line 32 to the load sorting conveyance line 33, and the bar code reader 36 is discharged from each storage shelf 21 of the storage 20 and enters the load sorting conveyance line 33. The type of the pallet 11 is read and input to the control computer. The type of the narrow pallet 11 is read from the bar code attached to the narrow pallet 11 or the case 1 thereon. However, identification means such as a two-dimensional code other than a barcode and an ID tag may be used.
[0032]
The transport conveyor 35 of the load sorting transport line 33 moves on the shipping place (platform 40), and a shipping zone 41 in which a roll box 42 assigned to each delivery destination (store) is attached to the front of the load sorting transport line 33 is provided. It is done. The conveyance conveyor 35 of the cargo sorting conveyance line 33 forms a plurality of picking zones 37 that form one for each of a plurality of, for example, two roll boxes 42 assigned to the shipping zone 41.
[0033]
At this time, based on the reading result of the bar code reader 36 described above, the control computer enters each picking zone 37 in which the roll boxes 42 from which the product of the narrow pallet 11 that has entered the load sorting conveyance line 33 is to be taken out are arranged. Sequentially, the narrow pallet 11 of the product type is automatically temporarily stopped. Then, in each picking zone 37, the control computer stops at each picking zone 37 on a picking indicator 43 (case picking indicator and loose picking indicator) provided corresponding to each roll box 42 in the shipping zone 41. The number of product items taken out of the narrow pallet 11 is lit up. The operator picks the number of articles displayed on the picking indicator 43 in the case 1 of the case 1 of the narrow pallet 11 or in the corresponding roll box 42 from the case 1 or the bulk transport container 2 to the corresponding roll box 42, and a completion button. When is pressed, the picking display 43 is turned off. When the picking in the picking zone 37 is completed, the narrow pallet 11 is transported to the next picking zone 37.
[0034]
The conveyance conveyor 35 of the load sorting conveyance line 33 is configured so that the narrow pallet 11 is positioned in the depth direction when viewed from the article take-out side by the operator in the picking zone 37. ing.
[0035]
In the cargo sorting and conveying line 33, a terminal 44 for displaying the number of remaining articles on the narrow pallet 11 (the case remaining number indicator and the rose remaining number indicator) is provided on the exit side (final end) of the final zone of the picking zone 37. ) And can be shipped and inspected by comparison with the actual remaining number on the narrow pallet 11 checked manually. If the comparison results match, input OK. If there is a discrepancy, the picking quantity of the discrepant type is redisplayed on each picking indicator 43 at the completion timing of the picking operation when all the picking indicators 43 that are lit in the picking zone 37 are extinguished, and the corresponding roll box 42 Check the actual number of picking and correct any picking mistakes or inventory data mistakes.
[0036]
The narrow pallet 11 that has entered the re-entry line 34 from the load sorting conveyance line 33 is assigned to an empty storage shelf 21 if there is a remaining narrow pallet 11, and an empty pallet if it is an empty narrow pallet 11. An accumulator 38 is assigned.
[0037]
Hereinafter, a shipping procedure of the picking automatic warehouse 10 will be described. For example, in a food factory, the picking automatic warehouse 10 performs low-temperature storage at 10 ° C to 2 ° C, and manages the expiration date for each product type (from old ones, do not give two products with the same expiration date). While the vehicle is shipped in units according to the specified delivery time, the driver picks, inspects, transports in the vehicle, and loads the vehicle (5-10 cases) from the vehicle-unit shipments on the platform (shipping place 40). In order to effectively use a limited amount of refrigerated space and increase shipping speed, the following procedure is used to increase the storage volume and pick each vehicle destination quickly and accurately by effectively using the automatic warehouse 10 with a certain space. To speed up shipping.
[0038]
(1) When the control computer receives an order for each vehicle destination, the control computer assigns a roll box 42 in the shipping zone 41 for each destination, calculates the total number of shipments by product type, creates batch shipment and picking data, and performs batch picking. Start.
[0039]
(2) From the inventory data of the storage shelf 20, the old product with the corresponding product and the expiration date (or the date of receipt) may be selected as a pallet to be shipped, and the goods to be taken out from the storage shelf 21 to the corresponding stacker crane 22. Issue a delivery instruction to the shelf location.
[0040]
(3) From the storage shelf 21 of the storage 20, use the stacker crane 22 to output the narrow pallet 11 of necessary items to be picked up to the output line 32. The product type of the narrow pallet 11 carried into the cargo sorting and conveying line 33 from the delivery line 32 is identified by the barcode reader 36, and this identification information is transmitted to the control computer.
[0041]
(4) Based on the identification information, the control computer transmits the picking data (including the remaining number data) of the shipping zone 41 by destination to the control device of the cargo sorting and conveying line 33, and the narrow pallet 11 is sent to the picking zone 37. Send it out.
[0042]
(5) When the narrow pallet 11 of the article type to be picked with respect to the roll box 42 corresponding to the picking zone 37 enters each picking zone 37 of the load sorting conveyance line 33, the narrow pallet 11 is moved to the picking zone 37. The picking zone 37 is temporarily stopped, and the picking quantity is lit on the picking indicator 43 (case picking indicator and rose picking indicator) of the roll box 42.
[0043]
(6) The operator looks at the picking indicator 43, takes out the necessary number of articles from the narrow pallet 11 in case units or loose units, stores them in the roll box 42, and presses the completion button. Turns off. When the operator is replaced with a picking robot, the picking display 43 is not necessary.
[0044]
(7) When the picking of the picking zone 37 is completed, the narrow pallet 11 starts to the next picking zone 37 and repeats picking based on the display of the picking indicator 43 in the next picking zone 37.
[0045]
(8) When the narrow pallet 11 arrives on the exit side of the final zone of the picking zone 37, the number of remaining articles that should be on the narrow pallet 11 is displayed on the terminal 44, and the actual remaining number checked manually. Shipment inspection is performed by comparison. If the comparison results match, input OK. If there is a discrepancy, the picking quantity of the discrepant type is redisplayed on each picking indicator 43 at the completion timing of the picking operation when all the picking indicators 43 that are lit in the picking zone 37 are extinguished, and the corresponding roll box 42 is displayed. Check the actual number of picking and correct the picking mistake. At the same time, if there is an inventory data error in the control computer, it can be corrected, and accurate inventory information can be obtained without an inventory operation.
[0046]
If a case remains in the narrow pallet 11 where the remaining number should be zero in the picking zone 37, the zero check photoelectric switch 45 (located slightly above the empty pallet) in the final zone is automatically detected. To inform the discrepancy. On the other hand, when there is no remaining number (zero) even though there should be a remaining number, a mismatch is automatically notified.
[0047]
(9) The narrow pallet 11 after shipment inspection enters the re-entry line 34, and the remaining narrow pallet 11 is re-entrerated to the empty storage shelf 21 using the stacker crane 22. The narrow pallet 11 that has been emptied enters the empty pallet stacker 38.
[0048]
According to this embodiment, there are the following operations.
(1) The pallet load of the narrow-width pallet 11 can reduce the size and weight of the same type of goods, store a variety of pallets in a fixed space, and install the automatic warehouse 10 in a narrow space.
[0049]
(2) The shelf size of the storage shelf 21 of the automatic warehouse 10 and the sizes of the conveyor lines 32, 33, and 34 can be narrowed corresponding to the narrow pallet 11, and a large number of cranes 22 can be installed in the same space. The number of delivery pallets (delivery capability) can be increased, the shipping speed can be increased, and the delivery time specification to the delivery destination can be easily handled.
[0050]
(3) When multi-item small-lot shipment is repeated, the pallet is removed from the storage 20 and the required number of items is taken out, and then the narrow pallet 11 with the remaining items is re-entered into the storage 20 again. Although the frequency of loading / unloading into / from the storage 20 is increased, a large number of cranes 22 can be provided according to the above (2), so that space productivity can be increased.
[0051]
(4) The size and weight reduction of the pallet load of the narrow pallet 11 can reduce the load capacity of the crane 22 described in (2) above.
[0052]
(5) Since the narrow width size is positioned in the depth direction when the conveying posture of the narrow pallet 11 is viewed from the article take-out side in the picking zone 37, the hand can easily reach the depth side of the pallet from the take-out side. Improve workability. Picking both case units and loose units can be performed directly from the narrow pallet 11.
[0053]
(6) Since the remaining number display terminal 44 is provided at the final end of the picking zone 37, shipping inspection can be performed by comparing this display remaining number with the actual remaining number on the narrow pallet 11 checked by hand, and the reliability of shipping. Can be improved. Based on the inspection result, the inventory data of the storage 20 can be corrected as necessary, and accurate inventory information of the storage 20 can be obtained regardless of the inventory work.
[0054]
In the picking automatic warehouse 10, the storage shelf 21 of the storage 20 can accommodate a high load shelf that can accommodate a pallet load with a high stacking height and a pallet load with a low stacking height. Both of the low load shelves to be stored can be provided, and such storage into the storage 20 and re-entry can be performed as follows.
[0055]
(1) Goods received
At the loading site 30 where the pallet load of the narrow pallet 11 to be loaded into the warehousing line 31 is loaded, the number of loading stages on the narrow pallet 11 is first set to the high shelf height by the instruction means connected to the control computer. Instructions for stacking as many as the number of steps that can be efficiently accommodated. The instruction means changes to a stacking instruction for the number of stages accommodated in the low load shelf height after the narrow pallets 11 are stored in all the high load shelves and all the high load shelves are in the storage state. The control computer stores the narrow pallet 11 stacked so as to fit in the high load shelf height into the high load shelf, and loads the narrow pallet 11 stacked so as to fit in the low load shelf height into the low load shelf. The stacker crane 22 is controlled so as to enter the warehouse.
[0056]
(2) Restocked goods
For the re-entry goods from the re-entry line 34 to the storage 20, a measuring means for measuring the height of the pallet load of the narrow pallet 11 is provided in the re-entry line 34, and the control computer is based on the measurement result of the measuring means, The stacker crane 22 is controlled so that the pallet load having a height that can be stored in the low load shelf is preferentially received into the low load shelf.
[0057]
Therefore, when the storage 20 having a high load shelf and a low load shelf is used, the following effects are obtained.
[0058]
Since the storage 20 includes a high load shelf and a low load shelf, the re-entry narrow pallet 11 whose number of stacking stages is reduced by repeated multi-item small shipments is placed in the low load shelf, and the narrow width of the low load shelf A decrease in storage efficiency due to the pallet 11 entering the high load shelf is avoided. At this time, at the time of warehousing, priority is given to warehousing on a high load shelf, and the loading (stage number) efficiency of the narrow pallet 11 is improved. At the time of re-entry, the storage efficiency of the automatic warehouse 10 is improved by giving priority to the entry to the low load shelf.
[0059]
Second Embodiment (FIGS. 3 to 5)
The second embodiment is different from the first embodiment in that, among the eight storage shelves 21 of the storage cabinet 20, six storage shelves 21 are used as the first storage division 101, and two rows are stored. The shelf 21 is used as the second storage section 102. The 2nd storage division 102 can be used for storage of the loose shipment goods which pick the goods in a case.
[0060]
The loading / unloading of the narrow pallet 11 with respect to the storage shelf 21 of the first storage section 101 is performed between the shipping line 32 and the re-entry line 34 by the stacker crane 22 as in the first storage section.
[0061]
In the second storage section 102, one of the plurality of storage shelves 21 is used as a warehousing frontage 51 and a warehousing frontage 52, and a conveyor 53 is arranged along the warehousing frontage 51 and the warehousing frontage 52, and the pallet load of the narrow pallet 11 is loaded. From the conveyor 53, it is possible to enter the storage shelf 21 via the storage entrance 51 and the stacker crane 22, and from any storage shelf 21 to the conveyor 53 via the stacker crane 22 and the exit opening 52.
[0062]
As shown in FIGS. 4 and 5, the second storage section 102 is moved up and down by a lifting device 54 between the lower standby position and the upper working position with respect to the conveyance level of the conveyor 53 on the front surface of the entrance entrance 51 and the exit entrance 52. A loading / unloading transfer 55 (motor 55A) is provided. The loading / unloading transfer 55 is set at the lower standby position so that the narrow pallet 11 can be conveyed by the conveyor 53, and is set at the upper working position so that the narrow pallet 11 can be loaded / unloaded with respect to the warehousing entrance 51 and the warehousing entrance 52. And
[0063]
The second storage section 102 is provided with a case picking indicator 56 and a rose picking indicator 57 at the upper part of the exit door 52, and is shipped from the narrow pallet 11 delivered to the exit port 52 to a second shipping zone 70 described later. The total number of articles to be displayed is displayed on the indicators 56 and 57. The total number of articles is taken out on the conveyor 53 from the case 1 of the narrow pallet 11 in units of cases and from the case 1 or the bulk transport container 2 in units of bulks. A completion button 58 is provided at the upper part of the exit door 52.
[0064]
The second storage section 102 has a load height detector 60 for detecting the height of the pallet load of the narrow pallet 11 received in the storage entrance 51, and the pallet load detected by the load height detector 60 is detected. According to the height, the height H of the storage shelf 21 that is the storage destination of the load can be adjusted. In the present embodiment, the load height detector 60 is configured by the light projecting and receiving devices installed on both sides of the warehousing entrance 51. In addition, a large number of pairs of pallet receivers 61 that form a pair on the left and right sides of the storage shelf 21 are fixed in a multistage shape with a small pitch up and down, and the narrow pallet 11 of this time is palletized by any stacker crane 22. The shelf height is adjusted by controlling whether to insert into the receptacle 61.
[0065]
Further, in the second storage section 102, the above-described shipping zone 41 is set as the first shipping zone, and a second shipping zone 70 is provided on the front surface of the conveyor 53, and the second shipping zone 70 is provided for each delivery destination (store). The assigned roll box 71 is attached and detached. The control computer uses the small picking indicators 72 (case picking indicator and loose picking indicator) provided in correspondence with each roll box 71 in the second shipping zone 70 to deliver the narrow goods that have been delivered to the aforementioned exit port 52. From the total number of articles taken out from the width pallet 11 to the conveyor 53, the number of product articles to be subdivided into each roll box 71 is lit and displayed.
[0066]
In the second storage section 102, the conveyor 53 is connected to each of the delivery line 32 and the re-entry line 34. As a result, the narrow pallet 11 delivered to the conveyor 53 from the delivery front port 52 is unloaded from the delivery line 32 to the load sorting conveyance line 33 as it is, and subjected to picking in each picking zone 37 of the load sorting conveyance line 33, and then re- It enters the conveyor 53 from the warehousing line 34 and re-entries from the warehousing front 51 or is assigned to the empty pallet accumulator 38.
[0067]
Hereinafter, the warehousing procedure and the leaving procedure of the picking automatic warehouse 10 including the first storage category 101 and the second storage category 102 will be described.
[0068]
(Goods receipt)
A product type with a small amount of collection is specified in advance, and “priority receipt product designation” is registered in the control computer.
[0069]
The control computer preferentially stores the products with a small shipment amount registered in the “priority storage goods designation” on the storage shelf 21 of the second storage category 102. When a quantity (P) within one pallet is stored in the second storage category 102, the same type pallet product newly received in the automatic warehouse 10 is stored in the storage shelf 21 of the first storage category 101. .
[0070]
Product items with a small shipment amount, such as “priority receipt goods designation”, are picked in a small amount in the second shipment zone 70 from the exit port 52 of the second storage section 102 via the conveyor 53, and in this second shipment zone 70. Can be performed in parallel with the picking in the first shipping zone 41 for other product types.
[0071]
(Shipping)
(1) Picking when P> 0
When the stock quantity P on the narrow pallet 11 by the second storage section 102 is larger than the total shipment number O, the article of O is directly taken out from the narrow pallet 11.
[0072]
That is, the narrow pallet 11 is delivered from the delivery opening 52 of the second storage section 102 to the conveyor 53, and O is taken out based on the display of the case picking display 56 and the loose picking display 57. Next, based on the display of the subdivision picking display 72 of each roll box 71 in the second shipping zone 70, the above-mentioned O is subdivided into each roll box 71. In the case where a JAN code or the like is attached to the delivery of O, the barcode can be read by the scanner attached to the second shipping zone 70, and the subdivision picking display 72 can be displayed for subdivision.
[0073]
In addition, a printer can be placed near the shipping front 52, and subdivision can be made by a subdivision list in which the number of items for sale is printed. In this case, the subdivision picking display 72 can be eliminated.
[0074]
(2) Picking when P ≦ 0
When the total number of shipments O is larger than the stock quantity P on the narrow pallet 11 in the second storage category 102, the goods are discharged from the shipping front 52 to the conveyor 53 with the narrow pallet 11 being loaded and loaded from the shipping line 32. All the stock items on the narrow pallet 11 are picked by transporting to each picking zone 37 of the sorting transport line 33. At the same time, the shortage (OP) is calculated by rounding up to the number of pallet units, the narrow pallet 11 having the calculated number of pallets is discharged from the first storage section 101, and from the output line 32 to the load sorting conveyance line 33. It transports to each picking zone 37 and picks an insufficient number (OP) of articles from the narrow pallet 11.
[0075]
The narrow pallet 11 delivered from the second storage section 102 is made into an empty pallet, and after confirming the final zero, it is assigned to the empty pallet accumulator 38.
[0076]
