Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to logistics for handling a wide variety of small-lot products, such as cosmetics, chemicals, clothing, electric parts, automobile parts, various character products, books, etc. The present invention relates to a picking cart that is used when a batch picking method is adopted when sorting products and quantities for each store.

[Conventional technology]

2. Description of the Related Art Conventionally, as a trolley used for sorting in a distribution center or the like, one having a table for loading several boxes for each shipping destination in a vertical or horizontal direction has been used. Picking is performed while moving this trolley along the row of storage shelves.

[Problems to be solved by the device]

Since the trolley cannot take a large number of containers to be loaded, it is necessary to reload the containers many times and reciprocate when there are many shipping destinations. Therefore, it is suitable when there are few shipping destinations and the number of articles to each shipping destination is large, but when there are many shipping destinations and the number of articles to each shipping destination is small, the work efficiency is poor.

In addition, when there are many types of goods, the storage shelves become long, so the distance for moving the trolleys becomes long, and if the trolleys are repeatedly loaded and moved as described above, the efficiency becomes even worse. .

If a batch picking system is adopted in which orders from a plurality of shipping destinations are picked into containers by product type, instead of storing articles by shipping destination, the number of times the storage shelves are reciprocated can be reduced and efficiency can be improved. However, when there are many types, the number of containers to be loaded on the trolley is insufficient, so that it is necessary to store a plurality of types of articles in the containers without distinguishing them. Therefore, when secondary picking is performed from the container on the trolley by shipping destination, it is necessary to rearrange the products by sort on a sorting shelf or the like again, and this rearrangement work is troublesome.

When the batch picking method is adopted, instead of providing a table on which a container is placed on a trolley, a storage compartment made up of partition shelves may be provided, which can increase the number of compartments. In this case, if the storage compartment is opened on the side surface with respect to the traveling direction of the trolley, the worker must turn around to store the article in the storage compartment of the trolley from the storage shelf,
Inefficient storage work.

If the storage compartment is opened on the front or rear surface of the trolley, the storage work is easy, but the number of storage compartments cannot be increased. If the number of storage compartments is increased, the width of the trolley becomes wider, which makes it difficult to perform storage work and makes it impossible to move a narrow passage between the storage rack rows. Also, if the width of the truck is wide, it is difficult to move.

The object of the present invention is to form a large number of storage compartments, to easily perform secondary picking when the batch picking method is adopted, and to easily store articles in the storage compartment during aggregate picking. Moreover, it is to provide a picking cart that can be easily taken out from the storage compartment.

[Means for Solving the Problems]

The picking trolley of this invention is provided with two split trolleys in which a plurality of storage compartments for storing articles according to product types are opened in the vertical plane, and these two split trolleys are back-to-back with the opened vertical planes of the storage compartments. It is provided with a connecting tool for connecting in the following direction. The connecting tool enables the two divided carriages to be arranged in the connected state or the disconnected state so that the open vertical surfaces of the storage compartments are aligned in the same direction.

[Action]

According to the configuration of the present invention, when the collective picking is performed from the storage rack, the two split trolleys are connected in a direction in which the open surfaces of the storage compartments face each other. Thus, the open surface of the storage compartment can be a front surface or a rear surface with respect to the traveling direction.

When carrying out the secondary picking, the two split carts are arranged side by side so that the open faces of the storage compartments are oriented in the same direction.

FIG. 6 is a schematic plan view of sorting equipment for batch picking using the picking cart 2. Storage shelf 1a
Is to store and store articles in a variety, and a large number of them are arranged to form a storage rack row 1. The storage rack rows 1 are arranged in parallel in a plurality of rows via a passage through which a picking cart 2 which is a portable storage means can pass. The intermediate storage rack row 1 is arranged in two rows with the storage racks 1a as back to back. The conveyor 4 conveys the containers 5 for each store. A guide board 3 is installed near the conveyor 4 and along which four picking carts 2 are arranged side by side.

As shown in FIG. 8, the storage shelf 1a has shelves 1 ₁ ... 1 _m ... 1 _n partitioned by a partition plate 40 for each stage, and the articles M are classified into the shelves 1 ₁ to 1 _n. Store separately.

As shown in FIG. 7, the conveyor 4 is a roller conveyor driven by a driving device 4a. The container 5 has a box-like shape with an open upper surface, and stores the article M therein.

FIG. 4 shows the guide board 3. The guide board 3 has guide windows 10 in upper and lower four stages, and a plurality of indicators 12 and an end switch 13 are provided on a cross rail 11 above the guide windows 10 in each stage. Reference numeral 14 is a leg portion of the guide board 3. Guide window 10
5 aligns with the storage compartments 7 on each stage of the picking cart 2 as shown in FIG. 5, and the indicator 12 and the end switch 13 are provided corresponding to each storage compartment 7. The display 12 is a digital display that displays numbers.

The display 12 and the end switch 13 are connected to a control device (not shown). The control device outputs a display signal to the display device 12 based on the type data of each storage compartment 7 of the picking cart 2 and the picking data for each store, and updates the display of the display device 12 by the input of the end switch 13. . Further, the control device causes the display device 12 to display the number of each product type to be collectively picked.

Next, a sorting method by this equipment will be described. When performing collective picking, as shown in FIG. 2, both split carriages 2A and 2B of the picking carriage 2 are connected in such a manner that the openings of the storage compartments 7 are back to back. In this state, the handle 27
The operator 6 holds and pushes the picking cart 2 to collectively pick articles from the storage rack 1a while moving the passage between the storage rack rows 1 as shown in FIG. This aggregate picking is performed according to an aggregate picking slip described later. The picked article is stored in the storage compartment 7 having the storage compartment number indicated on the picking slip.

In this case, the aggregate picking slip is created so that the articles picked from the storage rack 1a are sequentially stored from one of the split carriages 2A and 2B to the other. Therefore, when the storage in one of the split carriages 2A is completed, the picking carriage 2 can be rotated 180 °, and the storage compartment 7 of the other split carriage 2B can be opened facing the worker to continue picking. .

In the case of aggregate picking, when the number of articles is large and the storage space of the storage compartment 7 of the picking cart 2 is insufficient,
The shortage is stored in the preliminary storage section 8.

When a plurality of picking carts 2 are used as in this embodiment, a section of the storage rack row 1 to be in charge of each worker is determined. For example, as shown by the arrow in the figure, each worker 6 is in charge of moving the passage between the storage rack rows 1 from the conveyor 4 side in a U-shape.

When the aggregate picking is completed, as shown in FIG. 3, the grip 27 of the picking cart 2 is folded to form the two split carts 2.
A and 2B are in a connected state with the same orientation. In this state, the picking cart 2 stands by at the standby position Q behind the guide board 2 shown in FIG. Then, the picking carts 2 are arranged on the rear surface of the guide board 2. Here, after inspecting as described later, secondary picking, that is, picking for each store is performed. The picking for each store is performed by taking out the articles of the picking cart 2 from the front of the guide board 2 and storing them in the container 5 of the conveyor 4 for each store.

3 sets of 4 picking carts 2 are prepared, and while one set of picking carts 2 is performing collective picking from the storage rack 1a, another 1 set of picking carts 2 is set along the guide board 3 to store. Do another picking. The remaining one set of picking carts 2 stands by at the waiting position Q.

FIG. 7 shows the aggregate picking slip 17. The aggregate picking slip 17 is prepared for each picking cart in batch units, and the title section 17a indicating the picking cart No. and the batch No., the storage section number of the picking cart 2, the shelf address of the storage shelf 1a, Titles 17b to 17d of each item of picking quantity and display 17e corresponding to these
~ 17g has been applied. If the storage section number display 17e and the storage section number 20 (FIG. 2) of the picking cart 2 are associated with each other, picking mistakes are reduced. The aggregate picking slip 17 may be described together with the quantity by associating the product number with the shelf address.

The inspection and picking by store will be described.

When the picking cart 2 is arranged on the rear surface of the guide board 3 as described above, the respective indicators 12 of the guide board 3 are arranged in the respective storage compartments 7.
Each time, the number of articles to be stored by the aggregate picking is displayed in the storage section 7. According to this display, it is checked whether or not there is a predetermined number of articles in the storage compartment 7.

When the inspection is completed, each display 12 displays the number of picked containers in the first store-specific container 5. With this display,
Since the location of the storage compartment 7 to be picked and the number of pickings are known, the worker 6 takes out the article in the storage compartment 7 from the guide window 10 of the guide board 3 according to the display and stores it in the container 5 on the conveyor 4. When picking for one container 5 is completed, the end switch 13 is turned on. As a result, the display 12 displays the number to be picked in the next container 5. In this way, picking for each store is performed, and when picking for each store in batch units is completed, the picking cart 2 of the guide board 3 is replaced,
The following batch picking by store is performed.

According to the picking cart 2 of this configuration, the split carts are divided into two split carts 2A and 2B, and the open vertical surfaces of the storage compartments 7 of the split carts 2A and 2B are connected in a back-to-back direction. Storage compartment 7 for aggregate picking
Opens toward the front and back of the bogie traveling direction. Therefore, when the articles are stored in the storage compartment 7 from the storage rack 1, the worker 6 can perform the work without looking back, and the workability is good.

In addition, since the storage compartments 7 are provided in the two split carriages 2A and 2B, the width of the picking carriage 2 is not wide compared to the case where the same number of storage compartments 7 are arranged side by side only on the rear surface of one carriage, It is possible to pass even if the passage between the storage rack rows 1 is narrow.

In addition, since the storage compartments 7 are provided on the front and rear surfaces of the picking cart 2, the number of the storage compartments 7 can be increased, and even in the case of a large number of small products, the storage compartments 7 can be stored for each type. Therefore, the picking cart 2 can be used as it is as a sorting shelf at the time of secondary picking, and the rearrangement process according to product type on the conventional sorting shelf is unnecessary, and the efficiency of secondary picking is improved.

When performing secondary picking, the two split carriages 2A and 2B can be arranged side by side with the opening surface of the storage compartment 7 facing the same direction, so that picking can be performed simultaneously from both split carriages 2A and 2B.

In addition, by performing the secondary picking using the guide board 3, the picking efficiency can be increased as follows.
That is, the storage compartment 7 of the picking cart 2 is attached to the guide board 3.
Since the display device 12 for picking up the items is provided, it is only necessary to take out the specified number from the storage compartment 7 specified by the display device 12, and the conventional work of knowing and retrieving the item to be taken out from the store-specific slip is unnecessary. Become. Therefore, picking time can be shortened and picking mistakes can be prevented. Since the guide window 10 of the guide board 3 is provided for each step of the storage compartments 7, alignment accuracy with respect to the guide board 3 of the picking cart 2 is required as compared with the case where the guide windows 10 are individually provided in each storage compartment 7. Therefore, the picking cart 2 can be easily set. In addition, the partition between the guide windows 10 does not get in the way, which facilitates removal.

Even in the above-described inspection process, since the display is made on the display 12, it is possible to improve the inspection efficiency and prevent mistakes as in the case of picking for each store. Since the guide board 3 is used for both picking display and inspection display for each store, the structure is simple as compared with the case where they are provided separately.

The display 12 of the guide panel 3 may be capable of displaying the product number of the article as well as the number. When the product number is displayed, the correspondence between the product and the storage compartment 7 becomes clear at the time of picking by shop or inspection, the workability is improved, and mistakes are further reduced.

In the above-described embodiment, the aggregate picking is performed by the slip, but if the picking cart 2 is provided with a display for displaying the number of aggregate pickings, the shelf address, etc., the aggregate picking slip can be omitted, and the aggregate picking slip can be omitted. The picking efficiency can be improved.

Further, although the hinge 21 and the locks 26, 30 are used as the connecting tool 42 in the above-mentioned embodiment, the second lock 30 for locking the split carriages 2A, 2B in the same direction may not necessarily be provided. . Further, instead of the hinge 21 and the locking members 26, 30, a magnet or the like may be used as a connecting member. In that case, both split carriages 2A and 2B may be completely separated from each other. In short, the connector may have any configuration as long as the two split carriages 2A and 2B can be connected and moved in a back-to-back state and can be arranged in the same direction.

[Effect of device]

The picking trolley of the present invention is composed of two split trolleys, and both split trolleys are connected so that the open faces of the storage compartments face each other. The opening of can be directed forward and backward in the traveling direction of the carriage. Therefore, when the article is stored from the storage shelf to the storage compartment, the worker can perform the work without looking back, and the workability of the storage work is good. Further, since the storage compartments are provided in the two divided carts, the width of the picking cart does not become wider than in the case where the same number of storage compartments are arranged side by side only on the rear surface of one cart. For this reason, the storage work is further facilitated, and it is possible to pass even if the passage between the storage rack rows is narrow.

Moreover, since the storage compartments are provided on the front and rear surfaces of the picking cart, the number of storage compartments can be increased, and even in the case of a large number of small-lot products, the storage compartments can be stored for each type. Therefore, this picking cart can be used as it is as a sorting shelf at the time of secondary picking, and there is no need for a rearrangement process according to product type on the conventional sorting shelf, and the efficiency of secondary picking is improved.

When carrying out the secondary picking, since the two split trolleys can be arranged in the same direction as the opening surface of the storage compartment, both split trolleys can be taken out at the same time, and the take-out work can be easily performed.
