Description

The present invention relates to an order picking/packing system in a net supermarket distribution center, and more specifically, it eliminates the biggest problems in order picking/packing work at a net supermarket distribution center, such as walking, searching, and judging. , an order picking/packing system in a net supermarket distribution center that adopts a mechanism that allows picking and packing to be done easily and quickly.

In the ever-expanding Internet logistics business, the next need for customers is to purchase food items online, instead of going to supermarkets and shopping on a daily basis.

In other words, an increase in the number of customers who are said to be shopping refugees, such as the annoyance of having to go out to the store frequently and the store being too far away or being unable to go there, is leading to the expansion of online purchases.

However, in the Internet logistics business, food logistics requires advanced logistics technology such as freshness maintenance and temperature zone management. In addition, the unit price of products at online supermarkets is as low as around 200 yen per item, making it difficult to secure profits unless a highly productive, low-cost logistics system is built.

Orders for online distribution are mostly individual pieces. The most important part of bulk logistics is order picking, which costs the most.
In a general physical distribution system, products are replenished in the storage racks, and the method is to walk between the racks for each order and pick them up. The work at this time is often walking, searching, judging, etc., and the productivity is low. As a result, a picking worker picks about 100 to 150 pieces per hour.

Commonly seen batch picking and sorter sorting systems are available as methods of making the above order-based picking system more productive. This is a method in which multiple orders are placed together and automatically sorted by sorter equipment. Picking 20 or 30 orders at once will increase picking productivity.

Then, a high-speed sorter capable of sorting about 5,000 pieces per hour is used to sort by order. By storing products in an automated warehouse and picking them from the containers that have been discharged from the warehouse, there is no need for walking work, which is efficient.

However, in such a method, when the products are touched by picking and sent to the sorter, touching occurs, and after the products are sorted according to order by the shooter, packing work of putting them into plastic shopping bags or containers occurs.

These methods require high investment in equipment such as automatic warehouses and high-speed sorters, and the productivity is limited to 300 pieces per hour, which is about twice as high as that of picking by order.

In the Internet logistics business, the problem with mechanization is that, in the case of food products, there are perishable items and bottled items, and there are many products that cannot be sorted by high-speed sorters.
In addition, in batch picking from containers from automated warehouses, which is a large number of product touches, extra touch work such as placing perishables and bottled items in small trays and attaching bands to prevent them from shifting. is necessary,

After that, there is the work of putting it into a high-speed sorter, and after sorting, it is also necessary to pack it into boxes.
As described above, there is a lot of touch work before the order is put together and packed, and the problem is that these work cannot improve productivity.

Regarding the distribution system on the Internet described above, Japanese Unexamined Patent Application Publication No. 2015-145302 discloses "Work instruction device and collection and sorting method" (Patent Document 1).

In other words, it is intended to provide a new work instruction device and a new collection and sorting method that can efficiently collect and sort ordered products even if there is not enough work space. This is a collection and sorting device for a net supermarket that collects and sorts the products by orderer.

First, the ordered products are picked from the store in order of the number of orderers and placed in the sorting space. Next, the picked items are sorted preferentially for the orderer who has all the ordered items.

As a result, even in a store with only a small work space, it is possible to create one after another shipping containers for orderers in which all ordered products are available from a small amount of ordered products that have been picked.

On the other hand, Patent Literature 2 relates to a "picking and packing system" invented by the inventor of the present application.

Patent Document 2 describes a storage shelf provided with a plurality of rows of shelves for storing trays containing products, and a plurality of rows of trays in which the trays stored in predetermined rows of shelves are arranged in a vertical direction. a transfer device having a lifting device capable of moving up and down on a shelf, a shuttle that can move horizontally along the storage shelf, and a loop conveyor that transports the tray received by the shuttle; Picking type-specific lanes for selecting the destination of robot picking or worker picking for the trays placed on the loop conveyor and transporting them to each of them, and the trays whose destinations are selected in the picking type-specific lanes are arranged in a comb-like shape. A comb blade arm continuous vertical transfer machine or vertical lifter that receives with an arm and transfers in a vertical direction, and the comb blade arm continuous vertical transfer machine or vertical lifter transfers the product from the tray conveyed by the robot or the worker. and a sorter for sorting the commodities picked by the picking station.

This picking and merging system picks up specified commodities by taking out trays containing commodities, particularly at a distribution center, and further sorts and merges the commodities.

However, even in the case of the picking and matching system of Patent Literature 2, many touch operations are required until the orders are grouped and packed, and these include the problem that productivity cannot be improved.

JP 2015-145302 A Japanese Patent No. 6600727

The present invention will be further described.

In front of the picking/packing operator M, commodity storage boxes containing commodities to be order-picked and packed are carried by two rows of shipping conveyors. The reason why there are two rows of product storage boxes where product storage boxes flow is that when the picking of the product storage boxes on one side is completed, the product storage boxes descend and return to the shuttle automated warehouse. With the BOX, picking can be performed alternately from right to left, so that picking and packing can be performed continuously without waiting time with high productivity. On both sides of the picking/packing operator M, product storage containers, which are prefabricated finished product storage bodies with a capacity of, for example, 50 liters, are arranged on the right side in two rows of three boxes for six boxes, and on the left side in two rows of three boxes. 6 boxes, total 12 boxes are transported and set.

Three plastic shopping bags R, which are picking and packing materials, are previously placed in the commodity storage container, and their handles are hooked on hooks of the container.

The reason why the three shopping bags R are set in the container in advance is that the product can be taken out of the container together with the shopping bag and handed over to the customer at the time of home delivery, etc., and it is easy to load on a truck and the packing cost can be reduced. It enables

The picking work consists of 3 orders per box, 12 boxes on the left and right, and a total of 36 orders for batch picking.

In the foreground, a product storage box for storing and storing ordered products flows from the shuttle automated warehouse.

Also, the picking work is performed according to the picking instructions displayed on the display in front of the Vitzker. For example, if there is an instruction to put one product from the product storage box on the right into the fifth shopping bag R on the right, take one product and place it in the fifth shopping bag R in the middle of the second box on the right. It becomes the operation to put the product in. A laser beam is used to instruct the loading of the fifth shopping bag R to be loaded, and after the loading, a weight check is performed on a scale set on the bottom surface of the container to see if the correct products have been loaded.
An empty product storage box after picking is automatically lowered and returned to the shuttle automated warehouse, and the next product storage box is automatically sent out.

According to the first aspect of the invention, it is possible to provide an order picking/packing system in a net supermarket distribution center that eliminates many product touching operations and simplifies and speeds up picking and packing operations. can.

As described above, according to the order picking/packing system 1 in the net supermarket distribution center of the present embodiment, it is possible to eliminate many product touching operations and realize simplification and speeding up of picking and packing operations. becomes.
In addition, although the picking/packing operation has been described for the picking/packing of the goods into the shopping bag R, other goods are processed in the same way.

That is, at the picking/packing station 31, the worker M can perform batch picking and packing by order of up to 36 orders at once without walking around.

To date, most mechanized systems are a combination of batch picking and sorting. Therefore, the number of touches by the operator is large, and productivity is limited.

On the other hand, the picking/packing system of this embodiment can perform batch picking and packing at the same time, has a simple equipment configuration, and has high productivity.

In addition, perishables such as eggs, tofu, sake, meat packs, fruits, vegetables, etc., which are difficult to sort mechanically, are directly stored in the shuttle automated warehouse 2 in special containers from producers, and picking and packing operations are performed. It should be automatically conveyed in front of the operator.

At this time, if you combine logic such as throwing heavy items first, you can carefully and orderly put the items in the shopping bag that you hand over to the customer.

The shuttle automatic warehouse 2 can store milk, tofu, sake, and the like in dedicated containers as they are. If fruits and vegetables are packed by the producer, affixed with a bar code label, and transported to the distribution center as a dedicated product storage box 3, the products can be quickly stored in the shuttle automated warehouse 2 without being touched.

This is the completion of a unit load that eliminates waste from production to sales. Since there are many product items and a considerable capacity for loading and unloading cases in batch units is required, it is preferable to use a shuttle-type automated warehouse that is free of size, rather than a crane-type automated warehouse.

In this way, the order picking/packing system 1 according to the present embodiment eliminates the tasks of walking, searching, and judging, which are the biggest problems in the order picking/packing work, and anyone can easily, quickly, It has the unique effect of being able to pick and pack.

Moreover, this is an epoch-making system that enables batch picking of up to 36 orders at one time and packing by order without the operator M walking.

In addition, the productivity including picking and packing is estimated to be more than 600 pieces per hour, which is five times higher than picking by order and more than double the productivity of automatic warehouse and sorter sorting system. This will contribute to the reduction of logistics costs.

In addition, refrigerated goods and frozen goods can also be processed with high productivity in picking and packing by the same mechanism as the above-described case.

The present invention can be used not only for so-called BtoC net supermarket logistics but also for BtoB inter-store transport logistics.

As described above, according to the order picking/packing system 1 in the net supermarket distribution center of the present embodiment, it is possible to eliminate many product touching operations and realize simplification and speeding up of picking and packing operations. becomes.
Although the picking/packing work has been described for picking/packing products into the shopping bag R, other ordered products are also processed in the same way.

That is, at the picking/packing station 31, the worker M can perform batch picking and packing by order of up to 36 orders at once without walking around.

To date, most mechanized systems are a combination of batch picking and sorting. Therefore, the number of touches by the operator is large, and productivity is limited.

On the other hand, the picking/packing system of this embodiment can perform batch picking and packing at the same time, has a simple equipment configuration, and has high productivity.

In addition, perishables such as eggs, tofu, sake, meat packs, fruits, vegetables, etc., which are difficult to sort mechanically, are directly stored in the shuttle automated warehouse 2 in special containers from producers, and picking and packing operations are performed. It should be automatically conveyed in front of the operator.

At this time, if you combine logic such as throwing heavy items first, you can carefully and orderly put the items in the shopping bag that you hand over to the customer.

The shuttle automatic warehouse 2 can store milk, tofu, sake, and the like in dedicated containers as they are. If fruits and vegetables are packed by the producer, affixed with a bar code label, and transported to the distribution center as a dedicated product storage box 3, the product can be quickly stored in the shuttle automated warehouse 2 without being touched.

This is the completion of a unit load that eliminates waste from production to sales. Since there are many product items and a considerable capacity for loading and unloading cases in batch units is required, it is preferable to use a shuttle-type automated warehouse that is free of size, rather than a crane-type automated warehouse.

In this way, the order picking/packing system 1 according to the present embodiment eliminates the tasks of walking, searching, and judging, which are the biggest problems in order picking/packing work, and anyone can easily, quickly, It has the unique effect of being able to pick and pack.

Moreover, this is an epoch-making system that enables batch picking of up to 36 orders at one time and packing by order without the operator M walking.

In addition, the productivity including picking and packing is estimated to be more than 600 pieces per hour, which is five times higher than picking by order and more than double the productivity of automatic warehouse and sorter sorting system. This will contribute to the reduction of logistics costs.

In addition, refrigerated goods and frozen goods can also be processed with high productivity in picking and packing by the same mechanism as the above-described case.

The present invention can be used not only for so-called BtoC net supermarket logistics but also for BtoB inter-store transport logistics.
