JP-A-11-124205

In the above-described conventional article storage facility, since all of the storage bodies storing articles corresponding to the delivery information are transported as they are to the picking shelf, there are as many picking frontage as the number of types of articles to be delivered. Necessary.
Therefore, as the number of types of articles to be delivered increases, the number of picking frontage increases, and the picking shelf increases in size, leading to an increase in the size of the entire facility.

  The present invention has been made paying attention to such a point, and an object thereof is to provide an article storage facility capable of performing a picking operation while downsizing the facility.

In order to achieve this object, a first characteristic configuration of an article storage facility according to the present invention includes a storage shelf for storing a plurality of types of articles by type, and a storage shelf for taking out the articles from the storage body. A picking shelf that includes a plurality of picking frontage doors that can store the storage body in each picking frontage, transport means that transports the storage body between the storage shelf and the picking shelf, and the storage shelf. In addition to managing the storage state of the storage body in the box, the storage body storing the article corresponding to the delivery information is picked for each article type based on the delivery information including the type of goods to be delivered and the number of delivery items. Article storage provided with management means for performing a delivery process for operating the transport means so as to transport from the storage shelf to the picking shelf in a state of being divided into frontage doors Bei put,
Among the storage bodies that store the articles corresponding to the delivery information, the management means stores a plurality of types of storage bodies that store articles of a type in which the number of outgoings is less than the set number for mixed loading with respect to the mixed storage body. In other words, it is configured to carry out a mixed carrying process for operating the carrying means so as to carry the article to a mixed loading work place for storing the article in a mixed state.

That is, the management means performs the mixed loading processing, so that the storage body that stores the type of articles whose number of outgoings is less than the set number for mixed loading is transported to the mixed loading work location, and at the mixed loading work location. Since a plurality of types of articles can be stored in the mixed storage state in the mixed storage body, the mixed storage body can be transported to the picking shelf.
The storage means stores the articles corresponding to the delivery information among the storage bodies that store the types of articles whose number of delivery is equal to or greater than the set number for mixed loading by performing the delivery process. Therefore, it can be conveyed to the picking shelf as it is.

  Therefore, instead of simply transporting a storage body in which one type of article is stored to the picking shelf, a plurality of storage bodies that store types of articles having a delivery number of less than the set number for mixed loading are used. Since the mixed storage body in which various kinds of articles are stored in a mixed state can be transported, the number of picking slots can be reduced accordingly, and the picking operation can be performed while downsizing the equipment. We have been able to provide goods storage equipment that can be used.

  According to a second characteristic configuration of the article storage facility according to the present invention, the management means is configured to transfer the mixed storage body storing a plurality of types of articles from the mixed work location to the picking shelf. In that it is configured to operate.

  In other words, the management means operates the conveying means to convey the mixed storage body from the mixed work location to the picking shelf, so that the mixed storage body is removed from the mixed work location by using the already provided conveying means. It is possible to transport to the picking shelf, and it is possible to simplify the configuration for transporting the mixed storage body to the picking shelf.

The carriage-type mixed storage body is configured to be transported to a location adjacent to the picking shelf by manual operation.

In other words, the shelf storage type mixed storage body has a small number of articles to be stored by storing articles of a type with a large number of articles out of the types of articles with a number of goods output less than the set number for mixed loading. Even so, it is possible to store as many articles as the number of goods delivered.
In addition, in the cart-type mixed storage body, the number of articles to be stored can be reduced by storing the types of articles having a small number of articles out of the types of articles having the number of goods to be delivered out of the set number for mixed loading. However, the number of types of articles to be stored can be increased as much as possible.

  Therefore, with respect to the types of articles in which the number of outgoing items is less than the set number for mixed loading, it is possible to reduce the number of picking frontage required while storing the number of articles corresponding to the number of outgoing items in the mixed loading storage body. As a result, the equipment can be downsized and the efficiency of the picking operation can be improved.

  According to a fourth characteristic configuration of the article storage facility according to the present invention, the management means manages a plurality of grouped delivery information set in a form of delivering a plurality of different types of articles for each set as the delivery information, In the shipping process, based on one grouped shipping information selected from the plurality of grouped shipping information, a plurality of the storage bodies storing articles corresponding to the grouped shipping information are transported to the picking shelf. And when the picking end command means instructs the picking end of the grouped delivery information, the transport means is operated so as to transport the storage body from the picking shelf to the storage shelf. After performing the warehousing process, it is configured to perform a replacement process for executing the warehousing process based on the next one grouped merging information selected from the plurality of grouped merging information. .

That is, the management means handles the delivery process based on the selected delivery information of one group among a plurality of delivery information for each group, so that it corresponds to the selected delivery information at the picking frontage. The picking operation for the article can be performed.
Further, the management means performs the warehousing process on the basis of the one selected grouping evacuation information after the warehousing process, assuming that the timing of ending is reached by the picking end command by the picking end command means. By performing the replacement process, it is possible to perform the picking operation for the article corresponding to the next selected grouped delivery information in the picking frontage.

Then, the management means sequentially selects one by one for all of the plurality of grouped delivery information, so that the container transported to the picking frontage is replaced by the grouped delivery information unit at the time of delivery. Picking work can be performed for each group-based delivery information.
Also, since the number of types of articles corresponding to one group-based shipping information is smaller than the number of types of articles corresponding to shipping information consisting of a plurality of group-specific shipping information, the number of picking doors required is minimized. The number of articles handled in the picking work can be reduced as much as possible, and the equipment can be downsized and the efficiency of the picking work can be improved.

Incidentally, for example, when the corrugated cardboard packed with frozen food or the like is the article 3, it is necessary to provide the picking shelf 5 with equipment for preventing the frozen food from melting, but the number of the picking doors 4 is reduced. By being able to do so, the equipment can also be reduced in size and become more effective.

The management device H is a pallet that stores the items to be subjected to the above-described shipping process, among the pallets 1 that store the articles 3 that correspond to the group-based shipping information, and stores the types of articles 3 in which the number of shipping is equal to or greater than the set number for mixed loading. Among the pallets 1 that store the articles 3 corresponding to the grouped delivery information, the pallets 1 that store the types of articles 3 in which the number of delivered items is less than the set number for mixed loading are conveyed to the mixed loading work location 21. Thus, it is comprised so that the conveyance process for mixed loading which operates the conveyance means 6 may be performed.
Incidentally, the set number for mixed loading is, for example, half of the maximum number that can be stored in one pallet 1, even if multiple types of articles 3 are stored in a mixed state in one pallet 1, the stored articles 3 It is set so that it can store only the number of goods issued.

  To explain the mixed loading transport process, the management apparatus H stores, among the pallets 1 that store the articles 3 corresponding to the shipping information, the pallets 1 that store the types of articles 3 that are less than the set number for loading. Is selected from the pallets 1 stored in the storage shelf 2, and the pallet 1 storing the articles 3 corresponding to the selected grouped delivery information is selected.

Then, the management device H operates the transport means 6 so as to transport the selected pallet 1 to the mixed work place 21, but transports the selected pallet 1 to the pallet mixed work place 21 a depending on the number of items to be delivered. It is configured so as to distinguish one from the one to be transported to the mixed work place 21b for the carriage.
In other words, the management device H transports the pallet 1 storing the types of articles 3 whose number is larger than the set number for mixed loading, which is smaller than the set number for mixed loading, to the mixed loading work location 21a for pallets, and sets the number of discharged items. Is configured to be conveyed to the mixed work place 21b for the carriage.

  When the management apparatus H performs the mixed loading processing, the two types of articles 3a and 3b are mixed in the mixed pallet 24, for example, as shown in FIG. As shown in FIG. 4, for example, six types of articles 3 c to 3 h are stored in the pallet carriage 22 in a state of being classified in a separate manner. Has been.

  The management device H is configured to operate the transport means 6 so that the mixed pallet 24 is transported from the pallet mixed work location 21a to the picking shelf 5, and the picking cart 22 is picked manually. It is configured to be conveyed to a location adjacent to the shelf 5.

  In addition, the management apparatus H is the type of the pallet 1 that stores the articles 3 corresponding to the grouped delivery information, and the number of delivery is equal to or greater than the set number for mixed loading in the replacement process. The pallet 1 for storing the articles 3 is used, and among the pallets 1 for storing the articles 3 corresponding to the grouped delivery information, the pallet 1 for storing the types of articles 3 in which the number of delivery is less than the set number for mixed loading is used. It is configured to perform replacement processing.

  When the description is added to the mixed loading replacement process, the management apparatus H performs the loading process, and then performs the mixed loading transport process based on the next one grouped shipping information selected from the plurality of grouped shipping information. Configured to do.

  In the picking shelf 5 and the picking cart 22, in order for the operator to recognize the number of articles to be taken out from the pallet 1, the management device H takes out the articles to be picked up at the target store with respect to the customer to be picked up. The display processing for displaying the number of 3 on the picking number display section 17 in each picking opening 4 and each bogie opening 23 is performed.

For example, in the display process, when the customer who is the picking work target is the customer A, the management device H first displays the number of articles 3 to be picked up on the picking number display unit 17 for the store A1. When the picking completion button 18 for A1 is instructed by the pick completion button 18, the number of articles 3 to be taken out is displayed on the picking number display unit 17 for the shop A2, and the number of articles 3 to be taken out is sequentially displayed for each shop. It is configured as follows.
Then, when the picking work target customer becomes the next customer, the management apparatus H displays the number of articles 3 to be picked up on the picking number display unit 17 in a state in which the display of the next customer is sequentially changed for each store. It is configured to let you.

  Incidentally, in the picking frontage 4, as shown in FIG. 5A, the pallet 1 in which one kind of article 3 is stored, and as shown in FIG. Since there is the mixed pallet 24 stored, only the picking number display unit 17 located on the left side is displayed in the picking frontage 4 in which the pallet 1 storing one kind of article 3 is stored in the display process. In the picking frontage 4 in which the pallet 1 in which two kinds of articles 3 are stored is displayed, the picking number display unit 17 located on the left side and the picking number display unit 17 located on the right side are displayed. It is configured.

Moreover, since the picking slot 4 where the article 3 to be taken out is a part of the plurality of picking slots 4, the worker can easily recognize the picking slot 4 where the article 3 to be taken out exists. Therefore, as a display process, the management apparatus H may be configured to blink the pick completion button 18 provided in the picking slot 4 for the picking slot 4 where the article 3 to be taken out exists. .
Incidentally, in this case, the management device H is configured to cancel the blinking when the pick completion button 18 is pushed by the end of the picking work.

Since the management device H is configured to perform temporary placement processing and replenishment processing in addition to the above-described delivery processing, replacement processing, and display processing, the temporary placement processing and replenishment processing will be described.
First, the temporary placement process will be described. The management device H is based on one group-based shipping information selected from a plurality of group-based shipping information, and the pallet 1 that stores the articles 3 corresponding to the group-based shipping information. The conveying means 6 is configured to operate so as to convey a plurality of items 3 to the temporary storage shelf 12 from the storage shelf 2 in a state where the plurality of items 3 are classified.

  If it adds explanation, management device H will change all the pallets 1 which stored the article 3 corresponding to the selected grouped delivery information like the above-mentioned delivery processing only by the difference in the transportation destination of pallet 1. It is configured so as to be sequentially transported to the temporary storage shelf 12 in a state where the articles 3 are classified by type.

  Then, when the management apparatus H transports the pallet 1 to the temporary storage shelf 12, the article 3 of the same type as the article 3 transported to the picking storage unit 10 is adjacent to the picking storage unit 10. As in the case of transporting to the temporary storage unit 13, the type of the article 3 transported to the picking storage unit 10 and the type of the product 3 transported to the temporary storage unit 13 are transported in a corresponding state. It is configured.

  Next, the replenishment process will be described. The management apparatus H picks up an article shortage state in which the articles 3 stored in the pallet 1 are lost before the picking at the picking opening 4 among the plurality of picking openings 4 is completed. For the frontage 4, the conveying means 6 is operated so as to convey the pallet 1 temporarily placed on the temporary placing shelf 12.

When the explanation is added, the management device H uses the stacker crane 11 for picking shelves to transfer the empty pallet 1 stored in the picking frontage 4 in the state of insufficient goods, based on an artificial instruction or the like. 14, and the conveying means 6 is operated so as to be conveyed from the delivery unit 14 to the empty pallet accumulating device 16 by the cargo handling device 15.
When the management device H transports the empty pallet 1 to the delivery unit 14 by the stacker crane 11 for picking shelves in the picking frontage 4 in a shortage state of articles, the management device H is temporarily placed at the second stage on the upper side. In order to transport the pallet 1 stored in the storage section 13 to the picking frontage 4 in an article-deficient state by the stacker crane 11 for picking shelf, the transport means 6 is operated.

Incidentally, when the management apparatus H transports the pallet 1 from the temporary storage unit 13 located in the second stage to the picking frontage 4 in a shortage of articles, the temporary storage unit 13 located in the third stage. The pallet 1 stored in the container is transported to the temporary storage part 13 positioned at the second level, and the pallet 1 is transported from the storage shelf 2 to the temporary storage part 13 positioned at the third level. Therefore, the conveying means 6 is configured to operate.
In addition, the management device H is configured to replenish the articles 3 with respect to the storage shelves 2 using the cargo handling device 15 and the storage rack stacker crane 8.

And the management apparatus H is the object of the above-mentioned temporary placement process and the replenishment process among the pallets 1 storing the articles 3 corresponding to the grouped delivery information. The pallet 1 that stores the articles 3 of the type in which the number of goods to be delivered is less than the set number for mixed loading is basic among the pallets 1 that contain the goods 3 corresponding to the grouped delivery information. Is configured not to perform temporary placement processing or replenishment processing.
In other words, with respect to the temporary storage unit 13 located above the picking frontage 4 in which the mixed pallet 24 is stored, basically, the pallet 1 and the mixed pallet 24 are not stored. It is configured to remain empty.

The flow of the work for taking out the article 3 will be described based on the flowchart of FIG.
First, the management apparatus H determines whether each of the pallets 1 storing the articles 3 corresponding to the group-based shipping information is the pallet 1 storing the types of articles 3 in which the number of shipping is equal to or greater than the set number for mixed loading. Is determined (step 1).

And the management apparatus H conveys the pallet 1 which accommodated the articles | goods 3 corresponding to grouped delivery information to the picking shelf 5 by performing a delivery process about the pallet 1 whose delivery number is more than the setting number for mixed loading. (Step 2).
Further, the management device H stores the articles 3 corresponding to the grouped delivery information by performing the mixed carrying process for the pallets 1 that store the types of articles 3 in which the number of outgoings is less than the set number for mixed loading. The pallet 1 is transported to the pallet mixed loading work location 21a or the carriage mixed loading work location 21b (steps 1 and 3).

In the pallet mixed work place 21 a, when a plurality of types of articles 3 are stored in the mixed pallet 24, the mixed pallet 24 is transported to the picking shelf 5 by the transport means 6.
Further, in the mixed work place 21b for the carriage, when a plurality of types of articles 3 are stored in the picking carriage 22, the picking carriage 22 is transported to the picking shelf 5 by manual operation.

  Then, the management device H determines whether or not the determination of whether to perform the delivery process or the mixed transport process is completed for all the pallets 1 that store the articles 3 corresponding to the grouped delivery information. If it is determined that it is completed, display processing is performed to provide the number of articles 3 to be picked up in each of the picking frontage 4 and the carriage frontage 23 for the store where the goods 3 are picked up by the customer to be picked. The selected number is displayed on the picking number display section 17 (steps 4 and 5).

Thus, since the number of articles 3 to be picked up is displayed in the picking number display section 17 for each store at each picking frontage 4, the picking work is performed for each store according to the display, and the picked-up articles 3 The article 3 is transferred to the picking article conveyor 19 with a barcode or the like attached thereto.
In addition, although not shown, the articles 3 conveyed by the picking article conveyor 19 are collected for each store by a cart, and then loaded onto a truck or the like for delivery.

  Incidentally, since the picking article conveyor 19 is arranged in two upper and lower stages, when the article 3 taken out from a certain store is transferred to the picking article conveyor 19 located on the upper side, the article 3 taken out from the next store is taken. Are transferred to the picking article conveyor 19 positioned on the lower side, and the articles 3 taken out alternately are transferred to the upper and lower picking article conveyors 19.

  When the management device H performs temporary placement processing, the pallet 1 storing the articles 3 corresponding to the selected grouped delivery information is transported to the temporary storage shelf 12, and there is a picking frontage 4 in a shortage of articles. By performing the replenishment process, the pallet 1 is transported from the temporary storage shelf 12 to the picking frontage 4 in a shortage of articles (steps 6 to 8).

  Then, the management device H determines whether or not the picking work target customer has finished picking up the articles 3 from all the stores and the picking completion command is issued from all of the pick completion buttons 18 to finish picking the grouped delivery information. Is discriminated (step 9).

  The management device H indicates that the picking is finished for the grouped delivery information, and if the picking is not finished for all the delivery information, the pallet 1 storing the articles 3 corresponding to the next selected grouped delivery information is stored. For each of these, it is determined whether or not it is a pallet 1 that stores articles 3 of a kind whose output number is equal to or greater than the set number for mixed loading (steps 10 and 11).

Then, the management device H performs replacement processing for the pallet 1 whose number of deliveries is equal to or greater than the set number for mixed loading, and selects the pallet 1 of the picking shelf 5 for the article 3 corresponding to the grouped delivery information selected next. The stored pallet 1 is replaced (step 12).
In addition, the management apparatus H performs the mixed loading replacement process for the pallet 1 whose number of outgoings is less than the set number for mixed loading, and then stores the pallet 1 storing the articles 3 corresponding to the selected grouped outgoing information. It is made to convey to the mixed mounting work location 21 (step 13).
In this way, when it is determined and completed whether the replacement process or the mixed replacement process is performed for all of the pallets 1 storing the articles 3 corresponding to the next grouped delivery information selected. Then, the display process is performed for the article 3 corresponding to the selected grouped delivery information (step 14).
