Description

The present invention relates to an order picking and packing system in a multi-product BtoC distribution center, and particularly related to small products and small products in a wide variety of products, such as books, cosmetics, cosmetic accessories, electrical accessories, and DIY products (bonds, screws, metal fittings). , Sewing supplies (threads, dotans, etc.), as well as apparel flat products (folded T-shirts and underwear), etc. The purpose is to provide an order picking and packing system in a high-mix BtoC distribution center that can efficiently complete picking and packing of current products.

First, a conventional example of order picking in a distribution center will be described.

(Conventional example 1)
Conventionally, in a multi-product distribution center, the method of picking orders from customers is to store a wide variety of products on flat shelves installed in a vast warehouse, and workers walk around the area in charge to collect several ordered products. It was common to pick and sort the products collected from each area according to the customer's order. In this case, the picking work is to find the place of the shelf, walk to the corresponding location, and pick, the productivity is low. Therefore, in recent years, there are many methods in which a battery-powered automatic guided vehicle AGV (Automatic Guided Vehicle) lifts a shelf and transports it to a picking operator for picking. Picking productivity has improved because walking work, which is the biggest problem of the conventional method, has been eliminated. The storage efficiency of shelves can be improved by storing them in a high density without aisles, but the height of the shelves is limited to the reach of humans, and the height of the warehouse cannot be effectively used.

High-rise shelves are more efficient for storing a wide variety of products. There is also a crane-type automatic storage method, but it has a capacity of only about 80 boxes per crane to take out storage boxes, so it is not suitable for a wide variety of logistics.

In recent years, several systems have been developed around the world with improved storage efficiency and shipping capacity. It is called a shuttle warehouse, and has a shuttle that moves laterally to the shelves of high-rise storage shelves, and the shuttles of each stage take out the storage boxes from the shelves, demonstrating high shipping capacity.

In addition, a method with high storage efficiency has been developed in which one storage box is stored in the back instead of one (double deep). Since the shuttle also moves horizontally between shelves, a functional type that moves up, down, left and right has also been developed. In distribution centers that handle a wide variety of products, storage of many boxes and high-speed loading and unloading of storage boxes are required. Shuttle-type automated warehouses are suitable for these distribution centers.

The problem with a multi-product distribution center is how to efficiently pick and match orders from customers. In the online distribution of low-priced products, if two or three orders from customers are shipped separately, packing costs and delivery costs will increase, and no profit will be generated. It is essential to match orders by shipping several orders at once.

Even in a shuttle warehouse that can be efficiently loaded and unloaded, boxes containing ordered items are automatically taken out, but there are cases where the same product is ordered multiple times, in which case the storage box is returned to the shuttle warehouse after picking. It will be taken out and transported again, and it will be difficult to match the order.

If multiple orders can be processed in one storage box, efficiency will be improved. The order picking currently being developed in the world is a method of sorting from one storage box paid out from the shuttle warehouse to one or two boxes for order sorting, and five boxes at most.

As known examples of the above-mentioned conventional examples, Patent Documents 1 and 2 can be mentioned as known examples of the prior art invented by the present inventor.

Then, at the picking station 31, the picking worker M using the picking work data is in the 6-row, 5-stage pick tray 41 supplied and set on both the left and right sides while checking the display 52 of the instruction display. The ordered product in the storage box 3 instructed by the instruction display pick tray 41 is picked and put in while being picked.

Further, when the picking work according to the instruction display on the display 52 for one set of the 6-row 5-stage set is completed, the pick tray 41A after the picking is completed is conveyed and carried out to the packing station 60 by the transfer conveyor 34 in the next order. One set of 6 rows and 5 stages of picking trays 41 is carried in and set on both the left and right sides of the operator via the supply conveyor 33, and in connection with this, each storage box 3 in the following order is placed via the supply conveyor 32. It is supplied and carried in front of the worker M, and a predetermined picking operation is performed according to the instruction display of the next-order display 52 in the same manner as described above.

Example 2 of the order picking / packing system in the high-mix BtoC distribution center according to the present invention shown in FIGS. 4 to 7 will be described in more detail.

Regarding the second embodiment of FIGS. 4 to 7, the same reference numerals are given to the same configurations as those of the first embodiment, and the description thereof will be omitted.

Regarding the overall configuration of the order picking / packing system in the multi-product BtoC distribution center of the present invention in FIG. 4, the same configuration of the configuration of Example 1 is indicated by the same reference numeral, but the packing station is not shown in Example 1. 60 is arranged adjacent to the back of the picking station 31.

The packing station 60 is subjected to the required packing work described later by the packing worker M2, and the packing completion tray (not shown) is carried out by the packing line transfer conveyor 61.

As shown in FIGS. 5 and 6, the ordered products are stored in the hands of the worker M (picker) of the pick station 31 from the shuttle automated warehouse 2 via the upper and lower original boxes (storage boxes 3) supply lines 31A and 31B. The storage boxes 3 are supplied by the supply conveyors 32a and 32b (see FIG. 5) in two rows on the left and right.

The left and right storage boxes 3 supplied to the worker M are configured so that they can be statically set while being tilted toward the worker M in order to make it easier to see the inner boxes of both storage boxes 3. It is preferable to do so.

The left and right charge storage boxes 3 are sequentially supplied by the two rows of supply conveyors 32a and 32b, and in connection with this, the supply conveyors on both the left and right sides of the worker M of the picking station 31 are supplied. The empty pick tray 41 is supplied by 33a and 33b, and the pick tray 41 is supplied while being set in 6 rows and 5 stages by the vertically movable conveyors 50a and 50b on both the left and right sides arranged in front of the empty pick tray 41.

As for the pick tray 41 with 6 rows and 5 stages, as shown in FIGS. 5 and 6, one set of pick trays 41 with 6 rows and 5 stages has already been supplied to the pick work supply position and also to the standby supply position. Is configured so that the second set of 6 rows and 5 stages of pick trays 41a is set on standby on both the left and right sides.

Further, when the worker M at the picking station 31 completes the picking work from the storage box 3 for the pick tray 41 according to the instruction display of the display 52, each pick tray 41A is a packing line transfer conveyor by the vertically movable conveyors 51a and 51b on both the left and right sides. It is configured so that it can be carried out to 61.

Along with this, each storage box 3a for which the picking work of the ordered product for each storage box 3 in the pick station 31 is completed is automatically lowered after the picking is completed and is carried out to the shuttle automated warehouse 2 by the carry-out conveyor 35. ing.

Now, the action and effect in the order picking and packing system in the multi-product BtoC distribution center of the present invention having the above configuration will be specifically described below.

The present invention has been developed to provide an order picking and packing system in a multi-product BtoC distribution center capable of efficiently implementing these drawbacks in order to solve the above-mentioned drawbacks in the configuration and implementation status as a conventional example. It is a thing.

First, the basic work is to pick the number of orders from each storage box (original box) paid out from the shuttle automated warehouse 2 and sort and put them into the pick tray 41.

When the picking from the storage box 3 taken out from the shuttle automated warehouse 2 is completed, the picking of the next box is completed, but in most cases, the end box moves sideways and returns. In this case, it takes a few seconds before the next security box is set in front of the worker, and waiting occurs.

In the present invention, when the picking of the storage box 3 in the eyes of the worker M is completed, the conveyor on which the box is placed tilts forward and flows to the lower conveyor, and returns to the shuttle automated warehouse 2. By providing two rows of these, the picking worker M can immediately move to the picking work of the next box after the picking of the first box is completed.

In other words, picking work can be performed continuously without waiting time. In high-mix logistics, the number of picking lines and the number of picks per worker are important indicators for reducing logistics costs. How to eliminate waiting time and pick easily and quickly is important for improving productivity. This method, in which the storage boxes 3 are arranged in two rows in front of the picking worker M and can be picked alternately without waiting time, enables high productivity. Further, when two rows of boxes are arranged side by side, the lateral movement of the worker increases, but in the present invention, the horizontal width of the two rows of boxes is set to a little over 1 m, and the movement burden of the worker is reduced as much as possible.

Next is the assortment of ordered products. Most of the orders from customers are about 3 to 5, and how to balance them. A common example is picking several ordered products together, sending them to a high-speed sorter, sorting them by customer, and packing them. This method involves picking orders together (batch picking), sending them to a high-speed sorting sorter, and putting automatically sorted products into a tray, and each work is fast, but touch. There are many, and the total productivity is not high.

The present invention has been developed so that one worker can perform batch picking and order sorting. Therefore, the sorting trays 41 are arranged in 6 rows on both sides of the picking worker M, and the trays are arranged in 5 stages. That is, 30 trays are set within reach on one side of the worker M, and by setting these on both sides, a batch pick of 60 orders is possible.

Therefore, when processing the order data into picking data, if the computer is used to collect the orders with many orders for the same product in 60 orders, the picking hit rate from the storage box 3 will be high. That is, it is possible to reduce the number of times the storage box 3 is taken in and out of the shuttle automated warehouse 2.

The worker M can see the display 52 in front of the storage boxes 3 arranged in two rows and instantly understand which storage box 3 to take and how many products should be put into the left or right pick tray 41. Each pick tray 41 in 6 rows and 5 stages has an LED lamp, and the lamp is lit at the input tray. If the pick tray 41 is pulled out with the left hand and the product is put into the pick tray 41 with the right hand, the picking sorting is completed at the same time. If a different pick tray 41 is pulled out by mistake, an alert will be issued and mistakes can be prevented in advance. Therefore, it is preferable to equip the pick tray 41 with a configuration that enables the implementation.

As the picking and tray sorting proceed, the sorting of 6 trays in 1 of 6 rows and 5 stages is completed, and when completed, the 6 boxes in the completed stage are automatically dispensed by the vertically movable conveyor 51 (51a, 51b). The empty tray 41 is also supplied at the same time. When the pick trays 41 having 10 stages on the left and right are completely loaded and paid out, picking of the next 60 orders is continuously started.

The picking complete tray 41A that has been picked is conveyed to the packing station 60 by the packing line transfer conveyor 61. At the packing station 60, small orders are packed in bags and large quantities are put in cardboard boxes. Further, among the products of the picking completion tray 41A, those that can be automatically packed are automatically sorted and automatically packed.

As described above, the present invention is a mechanism that enables efficient picking and sorting of a wide variety of small items. There is no expensive high-speed sorter equipment that enables one worker M to perform picking and sorting with high productivity, which also contributes to investment cost and space reduction.

Picking and sorting productivity can be 600 lines or more per hour by one worker M. Picking in a wide picking area with a wide variety of varieties will be cart picking by area. The productivity is a little over 100 lines per hour, and when the sorting work is included, the total productivity is about 60 lines per hour. In the present invention, productivity of more than 10 times that of conventional cart picking can be secured. Moreover, the worker does not have to walk or search, and fatigue can be reduced.

Note that FIG. 8 is an explanatory diagram showing an example of designing a display instructed and displayed to an operator at the picking station in the second embodiment.

Explaining the design of the display 52, 53 is the screen of the display 52, and the screen 53 has the batch number 55 on the screen 53 from the left side on the inner upper side of the frame 54, and the center 2 squares are the left and right display columns 56 of the source Oricon. At 57, this display field 56 becomes the left Oricon indicator light of the worker M, and the display field 56 is lit (for example, a blue light), and the worker M is supplied to the left side by this lighting display with a 6-row, 5-stage pick. It is a pick instruction for the tray 41.

Further, the display column 57 on the right side becomes the right side Oricon indicator lamp, which is the right side Oricon instruction to the worker M by the lighting display such as blue, and the pick work instruction of the pick tray 41 to the right side 6 rows and 5 stages.

The picker, that is, the worker name (picker: Taro Yamada) is displayed in the display column 58 on the far right.

Further, in the square square 59a on the lower left side of the above column and the square square 59b on the right side thereof, the left side is the number of picks (2), and the right side is the instruction display column for the input Oricon location number display (No. 12).

As a result, in the lower column of the squares 59a and 59b, the tray numbers 1 to 3 in 6 rows of the pick tray 41 on the right side of the worker M are on the right side, and the pick trays 41 in 3 rows on the left side and 3 rows on the right side of 4 to 6 are. Although it is displayed, in the figure, the pick work has already been input in the work, and the indicator light (for example, blue light) is simply turned on to indicate that the indicator light indicating it is turned on, and the number of the pick tray 41 is Indicates a state in which the turned-off state is displayed.

Then, while the left source oricon indicator lamp 56 is lit, the pick instructions in the 6 rows of numbers 7 to 12 of the pick tray 41 on the left side indicate the number of picks of the square 59a, and the picks of the square 59b are picked. The number display of the tray 41, that is, the tray mass of the pick tray 41 of the number 12 of the pick tray 41 corresponding to the number 12, the color of the same tray mass is lit as the input oricon location display, and this blinks to cause the left pick tray. The pick tray 41 at the bottom of the 3 rows on the left side of the 6 rows of 41 is in the state of displaying the insertion instruction.

As a result, when two ordered products are picked from the storage box 3 supplied to the worker M and put into the tray of the number 12 of the pick tray 41, the number 12 of the pick tray 41 of the screen 53 is inserted. A blinking display of the square indicates that the input is complete.

Similar to the right pick tray 41, the number 12 display of the same square is turned off, the number 12 is not displayed, the square color changes to green, and it is displayed that the pick tray 41A has been put in.

The input of the picking work is as described in the description of the above embodiment. As for the display screen of the other margins of the screen 53, other implementations according to the embodiment of the design of the display 52 can be performed.
For example, the input button fields such as the remaining number field 53a, the correction button 53b, and the menu button 53c are set.

As is clear from the embodiment shown in FIG. 8, when the worker M is proficient in this, he / she can imagine the input location only by looking at the location number and can quickly input.

When the charging of the pick tray 41 is completed, the pick tray 41 mass turns green and is automatically dispensed, and then the empty pick tray 41 is conveyed and supplied via the pick tray supply conveyor 33. It is possible to carry out while configuring so that it can be set.

In the present invention, the storage box 3 in the eyes of the picking worker M has a mechanism that when the picking is completed, the upper conveyor 51a on which the storage box is placed tilts forward and flows to the lower conveyor 51b and returns to the shuttle automated warehouse 2. bottom. By providing two rows of these, the picking worker M can immediately move to the picking work of the storage box 3 on the adjacent side after the picking of the first left or right storage box 3 is completed.

In other words, picking work can be performed continuously without waiting time. In a wide variety of logistics, the number of picking lines and the number of picks per picking worker M are important indicators for reducing logistics costs. How to eliminate waiting time and pick easily and quickly is important for improving productivity. This method, in which the storage boxes 3 are lined up in two rows on both the left and right sides in front of the picking worker M and can be picked alternately without waiting time, has made high productivity possible. Further, when two rows of boxes are arranged side by side, the lateral movement of the worker increases, but in the present invention, the horizontal width of the two rows of storage boxes 3 is set to a little over 1 m, and the movement burden of the worker is reduced as much as possible.
