  As mentioned above, in the goods storage facility that stores the goods in the minimum stock quantity for emergency use in the storage department, the storage area for storing goods in and out of daily use and the minimum stock quantity for emergency use are secured. If the storage area for storing the goods to be stored is set to a separate storage area, and if an emergency does not occur for a long period of time, the storage area that secures the minimum stock quantity for emergency use The goods will not be delivered for a long time. As a result, the quality of goods with the minimum stock quantity deteriorates with the extension of the storage period, and when some or all of the articles with the minimum stock quantity for emergency use are issued, goods with deteriorated quality are issued. As a result, there is a risk of hindering the use of the goods after leaving the store.

  Accordingly, there is a need for an article storage facility that can store a minimum number of articles while preventing them from aging.

The characteristic configuration of the article storage facility according to the present invention includes a storage unit that stores a plurality of articles, a loading / unloading device that loads and unloads articles with respect to the storage unit, and when the articles stored in the storage unit are received. And a management control unit that manages the number of stocks and controls the warehousing operation and the warehousing operation of the warehousing device based on the warehousing request and the warehousing request, and the management control unit unloads the article from the storage unit In the article storage facility configured to control the output operation of the storage device so as to store the minimum number of articles in the storage unit,
In the storage unit, at least two different storage areas, a first storage area and a second storage area, are set as storage areas for storing a plurality of articles, and the allowable stock quantity in the first storage area is the minimum stock quantity. The management control unit is configured to allow the stock quantity in the first storage area to be larger than the minimum stock quantity when the goods are stored in the storage unit based on the warehousing request. It is configured to control the warehousing operation of the warehousing and unloading device so as to be warehousing, and the number of stocks in the first storage area when the goods are unloaded from the storage unit based on the warehousing request is the minimum stock. When the number is more than the number, the goods stored in the first storage area are removed from the remaining articles except for the articles in the first storage area, which are stored in the first storage area, in the order from the newest. In that it is configured to control the unloading operation before inlet-outlet device as.

According to this characteristic configuration, when the article is received into the storage unit based on the storage request, the first storage area receives the article so that the stock quantity in the first storage area is larger than the minimum stock quantity. The stock quantity in the storage area can be made larger than the minimum stock quantity.
When goods are delivered from the storage unit based on a delivery request, if the stock quantity in the first storage area is larger than the minimum stock quantity, the goods stored in the first storage area from the goods stored in the storage part Since the goods from the remaining items (goods that can be issued) are removed in order from the newest, the goods that are stored in the first storage area are repeated. The stock of goods stored in the storage unit is realized within a range in which the stock quantity of the product does not fall below the minimum stock quantity. Further, as the entering / exiting of the storage unit is repeated, among the articles stored in the first storage area, the articles secured as the minimum stock quantity at the time of delivery change to new ones. Accordingly, it is possible to prevent the minimum number of articles stored in the first storage area in the storage unit from being stored for a long period of time and being deteriorated over time.
In addition, when goods are delivered from the remaining goods (goods that can be delivered), except for the goods stored in the first storage area from the articles stored in the storage unit, the goods in the first storage area are removed in order from the newest, It is preferable that goods are delivered in order from the oldest goods. Thereby, first-in first-out of the articles stored in the storage unit is realized within a range where the number of articles stored in the first storage area does not fall below the minimum inventory number.
In addition, when the goods stored in the first storage area from the articles stored in the storage unit are removed from the remaining articles (articles that can be issued) except for the articles in the minimum stock quantity in the order of receipt, It is preferable that at least one article stored in the first storage area is delivered. As a result, if there is a delivery request, at least one article is reliably delivered from the first storage area, so compared to the case where goods are delivered from the goods that can be delivered including the articles stored in the second storage area. First-in first-out of articles stored in the first storage area is promoted. Further, when at least one article is delivered from the first storage area, it is preferable that the articles stored in the first storage area are delivered in order from the oldest article. Since the goods are stored in the order from the oldest, the goods that are stored in the first storage area will be discharged in order from the oldest at the time of storage, so that the first-in first-out of the articles in the first storage area is surely performed. Is called.
Since the articles stored in the first storage area are removed from the articles stored in the first storage area, the remaining articles (items that can be issued) are removed from the articles stored in the first storage area in the order from the newest. Even if the quantity of articles related to the delivery request is delivered, the minimum stock quantity of articles can be secured in the first storage area.
Thus, according to this characteristic configuration, it is possible to prevent the articles from aging over time while storing the minimum number of articles in the storage unit.
The first storage area and the second storage area do not need to be spatially continuous in the storage section, and may be configured by a set of area portions dispersed in a plurality of locations in the storage section.

Here, the management control unit, when receipts articles in the goods receipt request the storage unit based on, on the value inventory quantity is greater than the allowable less inventory quantity and the minimum inventory of a first storage area It is preferable that the warehousing operation of the warehousing / unloading device is controlled so as to preferentially enter the first storage area until reaching the set maximum stock quantity.

  According to this configuration, when an article is delivered from the storage unit, a state in which the number of stocks in the first storage area is larger than the minimum stock quantity can be made to appear actively, and the quantity of articles related to the delivery request is delivered. In this case, it is possible to improve the frequency with which articles are delivered from the first storage area. Thereby, first-in first-out of the articles stored in the first storage area is promoted.

  The storage unit stores a plurality of types of articles, the minimum inventory number and the maximum inventory number are set for each of the plurality of types of articles, and the first storage area is shared by the plurality of types. The maximum stock quantity for each of the plurality of types is set such that the sum of the maximum stock numbers for each of the plurality of types is less than or equal to the allowable stock quantity of the first storage area. Is preferred.

According to this configuration, since the sum of the maximum stock numbers for each of the plurality of types is equal to or less than the allowable stock number of the first storage area, the first storage area can be appropriately shared among the plurality of types, It is possible to secure a stock in a range of quantities between the minimum stock quantity and the maximum stock quantity.
For each of a plurality of types of articles, when the article is issued from the storage unit, among the articles stored in the first storage area, from the remaining articles excluding the articles with the smallest inventory number in the order of entry. Since the goods are delivered, it is possible to prevent a specific article from being stored in the storage unit for a long period of time and deteriorating over time in each of the plurality of types.
In this way, it is possible to prevent the articles from aging while securing the articles with the minimum stock quantity for each of the plurality of types.

  In addition, when the management control unit issues an article from the storage unit based on an emergency output request generated in an emergency as the output request, the inventory number in the first storage area is less than the minimum inventory number. It is preferable that the warehousing operation of the warehousing device is controlled so as to unload the article in a form that allows this.

According to this configuration, in an emergency, the articles in the first storage area are allowed to become the minimum stock quantity. Therefore, for example, among the articles stored in the first storage area, the minimum stock quantity is in order from the newest at the time of receipt. If the stock quantity of the remaining goods excluding the goods in stock and the stock quantity in the second storage area are small, the stock status is such that the quantity of goods related to the delivery request cannot be delivered if it is a normal delivery request. In addition, based on the emergency delivery request, the quantity of articles related to the delivery request can be appropriately delivered from the storage unit.
In this way, in the event of an emergency, by relaxing the delivery limit for the first storage area, when an emergency delivery request occurs, it can be appropriately handled without causing a shortage.

  The storage unit is configured by an article storage shelf in which at least one article is stored in a plurality of stages in the vertical direction and in a plurality of rows in the horizontal direction of the shelf, and the lowest storage in the article storage shelf. A plurality of storage units belonging to a plurality of stages from a part to a set number of stages are set in the first storage area, and a plurality of storage parts not belonging to the first storage area in the article storage shelf are in the second storage area It is preferable that it is set.

According to this configuration, since the first storage area is set in a plurality of storage units positioned below including the lowest stage of the article storage shelf, the first storage area is arranged close to the floor surface. Therefore, even when the loading / unloading apparatus does not operate, the articles stored in the first storage area can be unloaded by the hands of an operator who moves on the floor. Therefore, for example, even in the case of an emergency, even when the loading / unloading apparatus does not operate due to a power failure or failure, the minimum number of articles stored in the first storage area can be taken out from the storage unit.
In addition, some or all of the plurality of storage units constituting the second storage area are set in the plurality of storage units belonging to a plurality of stages from the lowest storage part to the set number of stages in the article storage shelf. Also good. Each of the plurality of storage units may store one article or may store a plurality of articles.

The conveyance operation of the crane 5 is controlled.

  In this way, the inventory management device C and the transport control device H manage the warehousing time of the lamp L stored in the storage unit 1 and the number of stocks, and the warehousing operation of the warehousing device based on the warehousing request and the warehousing request. In addition, since the inventory operation is controlled, the inventory management device C and the transport control device H have the function of the management control device of the present invention.

  The outline of the operation of the worker when the lamp L is stored is as follows. Although not shown in the figure, a barcode reader 8 is installed at the entry place of the container 4 in the line conveyor 7 on each floor, and the barcode attached to the container 4 to be stored is read by the barcode reader 8 so that the reading can be performed. When completed, a container information reading completion button provided in the terminal device provided at the input location is pressed. Subsequently, the barcode attached to the lamp L scheduled to be accommodated in the container 4 is read by the barcode reader 8 and sequentially accommodated in the container 4 from the end of the reading. This operation is repeated for all the lamps L scheduled to be mixedly loaded in the container 4 (there may be less than the allowable number of mixed loads), reading the barcodes of all the lamps L mixedly loaded in the container 4 and the container 4 When the storage is completed, the warehousing setting completion button provided in the terminal device provided at the input location is pressed.

  When the worker reads the barcode of the container 4 and the lamp L, the lamp identification unit C1 of the inventory management device C functions, and the lamp L is the first type lamp from the barcode information of the lamp L. L1 identifies the type of lamp L among the 20th type lamps L20, and the container identification unit C2 functions to determine the container type based on the difference in the number of partitions from the barcode information of the container 4. . When the barcode attached to the lamp L to be mixed is sequentially read, the allowable number of mixed loading for the lamp ID of the lamp L that is read first matches the number of partitions of the container 4 determined by the container identification unit C2. If not, the error information is notified to prevent the mixed number of the lamps L accommodated in the container 4 from becoming inappropriate. Further, if the error information is notified when the lamp ID is different from the lamp ID of the lamp L read immediately before, the storage unit in a state where the different types of lamps L are erroneously accommodated in the container 4. 1 can be prevented from being stored.

  When the worker presses the warehousing setting completion button, a warehousing request is generated. That is, the warehousing setting completion button functions as the warehousing request unit 9. Note that the warehousing request unit 9 may be realized not only by the warehousing setting completion button but also by a voice or other input device. When the warehousing request is generated, the warehousing date setting unit C3, the lamp unit discriminating unit C4, and the warehousing destination determining unit C5 function. However, the lamp classifying section C4 functions only when there is a storage request for the lamp L that satisfies the installation standard, that is, a storage request from the third floor.

  As the warehousing request, the warehousing request issued from the entrance on the first floor in order to store the lamp L after the cleaning process into the storage unit 1, and the lamp L after inspection and necessary parts replacement are stored in the storage unit 1. In order to do this, a storage request issued from the maintenance room on the second floor and a lamp L after adjustment of the optical axis (lamp L satisfying the installation standard) are issued from the light distribution room on the third floor to store in the storage unit 1. Although there is a warehousing request, the present invention is applied to warehousing control for a warehousing request issued from a light distribution room on the third floor.

  Further, in the lamp storage facility according to the present embodiment, the shipping request is a shipping issued from the maintenance room in order to release the lamp L stored in the storage unit 1 to the maintenance room on the second floor after the cleaning process. Request, delivery request issued from the light distribution room to deliver the lamp L stored in the storage unit 1 to the light distribution room on the third floor after inspection and necessary parts replacement, optical axis adjustment, etc. There is an unloading request issued from the unloading port in order to unload the lamp L that satisfies the installation standard stored in the storage unit 1 to the unloading port on the first floor. The present invention is applied to delivery control for a delivery request to be made.

  As described above, in the lamp storage facility according to the present embodiment, the storage unit 1 stores not only the lamp L that has been maintained and meets the installation standard and can be carried out to the exit, but also the lamp L to be maintained at the same time. The storage unit 1 is loaded and unloaded, but the first type lamps L1 to L1 that are emergency lamps when a loading request and a loading request for the lamp L satisfying the installation standard are generated. Since the present invention is applied in the warehousing control and the warehousing control related to the type 5 lamp L5, in the following, when a warehousing request and a warehousing request are generated for the maintained lamp L, that is, a light distribution room on the third floor The control operation of the inventory management device C and the transport control device H when a store entry request from the storehouse and a store request from the first floor unloading port are generated will be described. First, warehousing control of the inventory management device C and the conveyance control device H when a warehousing request is generated from the light distribution room on the third floor will be described.

  When the warehousing request is generated, the warehousing date setting unit C3 functions to acquire the date and time when the warehousing request is generated from the clock built in the inventory management device C as the time of warehousing. In addition, you may acquire the timing which the warehousing date setting part C3 acquires at the time of warehousing at another timing, such as the timing when the actual container 4 was warehousing.

  When the warehousing request is generated, the lamp classification discriminating unit C4 functions, so that the lamp is identified based on the lamp ID of the lamp L to be stored and the classification information of the lamp L stored in the lamp information storage unit D2. The lamp section of the lamp L is determined. For example, when the illuminating target lamp L is the second type lamp L2, the lamp ID read by the barcode reader 8 is “02”, so that the second lamp as shown in FIG. The classification of the seed lamp L2 is determined as an “emergency lamp”. Further, when the lamp L targeted for warehousing is the 15th type lamp L15, the lamp ID read by the barcode reader 8 is “15”. Therefore, as shown in FIG. The classification of the seed lamp L15 is determined as “ordinary lamp”. The determination result is held in a storage unit provided in the inventory management apparatus C. That is, using the emergency lamp classifier flag for the illuminating target lamp L that is currently being processed, the emergency lamp classifying flag is set if the tentative lamp L is an emergency lamp. The determination result is temporarily held.

  As shown in FIG. 3, the storage unit 1 includes two different storage areas (a first storage area and a second storage area according to the present invention) as storage areas for storing a plurality of lamps L. Storage area) is set. A part of the storage unit 3 belonging to the second zone Z2 may be set in another storage area as an area for storing a specific type of lamp L, for example. The first zone Z1 is shared by five types of emergency lamps, the first type lamp L1 to the fifth type lamp L5, and each of the plurality of types should be secured as inventory in the first zone Z1. The minimum inventory quantity and the maximum inventory quantity that is the limit of the inventory quantity that can be stored in the first zone Z1 are set.

  For the lamps L belonging to the category of emergency lamps, that is, the five types of lamps L, the first type lamp L1 to the fifth type lamp L5, at least the minimum stock quantity is stored in the storage unit 3 belonging to the first zone Z1. It is supposed to be. Even if the number of stocks of the lamps L of the type increases, the maximum stock number set for each type is stored as a limit, and more lamps L are stored in the storage unit 3 belonging to the second zone Z2. It is designed to be stored.

  When the warehousing request is generated, the warehousing destination determination unit C5 functions, so that the warehousing destination of the illuminating target lamp L from the empty storage unit 3 of the storage unit 1 based on the luminaire classification of the illuminating target lamp L. Is selected. When the lamp L targeted for warehousing is an emergency lamp, that is, when the type of the lamp L targeted for warehousing is one of the first type lamp L1 to the fifth type lamp L5, the first zone Z1 Priority is given to the storage unit 3 belonging to, and after the stock quantity of the type in the first zone Z1 reaches the maximum stock quantity, the storage unit 3 belongs to the second zone Z2. If the classification of the type of lamp L to be stored is a normal lamp, the lamp is stored in the storage unit 3 belonging to the second zone Z2 in principle. Such sorting of the storage unit 3 at the warehousing destination is performed when a warehousing request is generated for the lamp L that satisfies the installation standard from the light distribution room on the third floor, and is generated from the first floor or the second floor. When a storage request for the lamp L that does not yet meet the installation standard to be generated is generated, the empty storage unit 3 belonging to the second zone Z2 is selected in principle.

  In this way, the inventory management device C allows the inventory quantity in the first zone Z1 to be larger than the minimum inventory quantity when the lamp L, which is an emergency lamp, is received in the storage unit 1 based on the receipt request. The loading operation of the stacker crane 5, the loading / unloading conveyor 6 and the line conveyor 7 is controlled so that the lamp L is received in the form to be performed. Specifically, when the inventory management device C receives the lamp L in the storage unit 1 based on the warehousing request, the inventory quantity in the first zone Z1 is less than the allowable inventory quantity and larger than the minimum inventory quantity. The warehousing operation of the loading / unloading device (stacker crane 5, loading / unloading conveyor 6 and line conveyor 7) is controlled to prioritize the first zone Z <b> 1 until the set maximum stock quantity is reached.

  About each of the five types of emergency lamps so that the sum of the maximum inventory numbers for each of the first type lamp L1 to the fifth type lamp L5 which are emergency lamps is equal to or less than the allowable inventory number of the first zone Z1. The maximum stock quantity is set. Naturally, the allowable stock quantity of the first zone Z1 is larger than the minimum stock quantity of each of the various types of emergency lamps.

  In the present embodiment, as shown in FIG. 3, a plurality of storage units 3 belonging to a plurality of stages (four stages) from the lowest stage storage part 3 in the article storage shelf 2 to four stages are set in the first zone Z1. The plurality of storage units 3 that are set and do not belong to the first zone Z1 in the article storage shelf 2 are set to the second zone Z2. Specifically, 256 (16 bays × 4 levels × 4 banks) storage units 3 belonging to four levels of level numbers “01” to “04” of the four article storage shelves 2 in the storage unit 1 are the first. One zone Z1 is set. As the storage destination determination unit C5 functions, the lamps L of the first type lamp L1 to the fifth type lamp L5 that are emergency lamps are preferentially selected from the 256 storage units 3 belonging to the first zone Z1. The goods receipt destination is selected.

  By setting the first zone Z1 to the storage unit 3 having a low level close to the floor of level numbers “01” to “04” in this way, even when the loading / unloading device does not operate due to a power failure or failure due to an earthquake, etc. The lamp L stored in the first zone Z <b> 1 can be discharged by a worker who moves on the floor. For this reason, for example, even if the storage / removal device does not operate due to a power failure or failure despite an emergency, the lamp L with the minimum inventory number stored in the first zone Z1 is taken out from the storage unit 1. Can do.

  The maximum stock quantity of each of the five types of emergency lamps is set as shown in FIG. 7, and the maximum number of first type lamps L1 is 80 and the number of second type lamps L2 is 70. A maximum of 50 type 3 lamps L3, a maximum of 30 type 4 lamps L4, and a maximum of 25 type 5 lamps L5 are stored in the storage section 3 of the first zone Z1. It can be done. Since the total of these maximum stock numbers is 255, it is 256 or less which is the allowable stock number of the first zone Z1.

  The maximum stock quantity is set when the accommodation efficiency of the lamp L with respect to the container 4 stored in the first zone Z1 is the lowest, that is, only one container 4 is stored in the first zone Z1. Although it is set on the assumption that the lamp L is accommodated, in reality, since a plurality of lamps L of the same type are mixedly loaded in one container 4, the first type lamp L1 in the first zone Z1. -Even if each of the inventory quantity of the fifth type lamp L5 has reached the maximum inventory quantity, the occupied storage unit 3 is less than the total of these.

  Next, the delivery control of the inventory management device C and the transport control device H when a delivery request from the first floor unloading port is generated will be described. When the worker presses a planned shipping button provided in a terminal outside the figure provided at the carry-out port on the first floor, a shipping request is generated. That is, the planned delivery button functions as the planned delivery request unit 10. In the shipping request from the planned shipping request unit 10 in the present embodiment, shipping is requested by the planned shipping number shown in FIG. 7 for all types of lamps of the first type lamp L1 to the 20th type lamp L20.

  When a delivery request is generated, the inventory management device C starts delivery control in order to deliver the lamps L of the planned number of delivery preset for each lamp type to the exit as shown in FIG. The inventory management device C, when issuing the first type lamp L1 to the fifth type lamp L5, which are emergency lamps, from the storage unit 1 based on the output request, for the planned number of outputs, is the number of inventory in the first zone Z1. Is larger than the minimum stock quantity, the lamp L of the minimum stock quantity is removed from the lamp L stored in the storage unit 1 in the order of the new receipt date among the lamps L stored in the first zone Z1. The unloading operation of the stacker crane 5, the loading / unloading conveyor 6 and the line conveyor 7 is controlled so as to unload the lamp L from the remaining lamp L (planned unloading possible lamp). As a result, the emergency lamp can be stocked in the first zone Z1 in excess of the minimum stock quantity.

  When a shipping request is generated, the shipping source determination unit C6 of the inventory management device C functions for each lamp type that is a shipping target in the shipping request. That is, the inventory management apparatus C refers to the inventory information stored in the inventory information storage unit D1, and the lamp classification of the lamp L to be delivered is an emergency lamp (first type lamp L1 to fifth type lamp). In the case of the container L5), the lamp L with the minimum inventory number is removed from the lamp L of the type stored in the storage unit 1 in the order of the latest receipt date among the inventory stored in the first zone Z1. From the remaining lamps L, the storage unit 3 as a shipping source is determined so as to discharge as many lamps L as possible in order from the oldest loading date. In addition, when selecting the lamp L of the number of goods requested by the goods issue request in order of the warehousing date, the minimum quantity of containers 4 exceeding the number of goods requested by the goods output request is selected as the object 4 to be delivered, The storage unit 3 storing these containers 4 is selected as the storage unit 3 that is the source of the delivery.

  As described above, the inventory management device C, when issuing the first type lamp L1 to the fifth type lamp L5, which are emergency lamps, to the storage unit 1 based on the output request, The unloading operation of the stacker crane 5, the loading / unloading conveyor 6 and the line conveyor 7 is controlled so that the lamp L is stored.

  An emergency exit request (corresponding to the emergency exit request according to the present invention) is generated when an operator presses an emergency exit button provided in a terminal (not shown) provided at the first floor unloading port in an emergency. That is, the emergency shipping button functions as the emergency shipping request unit 11. An emergency when the emergency exit button is pressed is, for example, a case where an aircraft makes an emergency landing such as a fuselage landing on a runway. When an emergency landing occurs, the lamp L damaged at the time of landing will be replaced. At least the first type lamp L1 to the fifth type lamp which are emergency lamps for quick recovery of the airport function. For L5, it is necessary to prepare for the delivery of each planned number of deliveries. In the present embodiment, even in the case of an emergency shipping request, all types of lamps L having lamp IDs “01” to “20” are targeted for shipping, as in the case of the planned shipping request.

  When the emergency exit request is generated, the inventory management device C first outputs the first type lamp L1 to the fifth type lamp L5 as emergency lamps from the storage unit 1 based on the emergency output request. The stacker crane 5 and the entrance are provided so that five types of emergency lamps (first-class lamp L1 to fifth-class lamp L5) are delivered in a form that allows the number of inventory in the zone Z1 to be smaller than the minimum inventory quantity. The operation of the delivery conveyor 6 and the line conveyor 7 is controlled.

  The inventory management realized by the lamp identifying unit C1, the container identifying unit C2, the warehousing date setting unit C3, the lamp unit classifying unit C4, the warehousing destination determining unit C5, the leaving source determining unit C6, and the conveyance command unit C7 described above. The control operation in the warehousing control and the warehousing control of the device C will be described along the flowcharts of FIGS. In addition, warehousing control is the process about one container 4 of warehousing object, and warehousing control is the process about the container 4 of warehousing object.

  First, warehousing control when a warehousing request is generated from the light distribution room on the third floor will be described with reference to the flowchart of FIG. Until a warehousing request is generated in the warehousing requesting section 9, it is in a standby state in step # S1. When the worker presses the warehousing setting completion button and a warehousing request for one container 4 containing a certain type of lamp L is generated, the process proceeds to step # S2, and the barcode reader 8 performs the warehousing setting work. Based on the read barcode information of the lamp L and the lamp classification information stored in the lamp information storage unit D2, it is determined whether the lamp L is an emergency lamp or a normal lamp.

  If the lamp L to be stored is an emergency lamp, the process proceeds to step # S3, and if it is a normal lamp, the process proceeds to step # S5. If the lamp is an emergency lamp, it is determined in step # S3 whether the inventory quantity in the first zone Z1 of the lamp L of that type has already reached the maximum inventory quantity based on the information in the inventory information storage unit D1. If the maximum stock quantity has not been reached, the process proceeds to step # S4, where one storage unit 3 that is a warehousing destination is searched for the storage units 3 belonging to the first zone Z1 according to the set search condition, It is allocated as the storage unit 3 at the warehousing destination.

  Note that the setting search condition for searching for the empty storage unit 3 is that the empty storage unit 3 is searched in the first zone Z1 in order from the lowest level number of the storage unit 3 of the zone to be searched. If there is no space, search for the empty storage unit 3 of the same level number, the odd number of the bay number, and the even number bank from the bay number in order from the lowest bay number in order from the lowest three storage units. Will increase. When the bay number reaches the maximum value 16, the level number is incremented by one, and an empty shelf is searched in the bay direction from the smallest bay number.

  When the lamp L to be stored is a normal lamp in step # S2 or when the stock quantity in the first zone Z1 reaches the maximum stock quantity in step # S3, the process proceeds to step # S5. The storage unit 3 belonging to the second zone Z2 is searched for one empty storage unit 3 as the storage destination according to the set search condition, and the found storage unit 3 is assigned as the storage unit 3 as the storage destination.

  When the storage unit 3 of the warehousing destination is determined in step # S4 or # S5, the process proceeds to step # S6, where the lamp ID of the illuminating target lamp L, the container ID of the container 4, the warehousing date, and the warehousing destination. Are stored in the inventory information storage unit D1 in association with each other. In this way, when the inventory information of the warehousing target lamp L is stored, the conveyance control device H is instructed with a conveyance command for warehousing with the storage unit 3 of the warehousing destination as the conveyance destination. Thereby, the container 4 which accommodated the lamp | ramp L which is a warehousing object is relayed and conveyed with the line conveyor 7, the warehousing conveyor 6, and the stacker crane 5, and is stored in the storage part 3 of the designated storage part address.

Next, unloading control when a unloading request from the first floor unloading port is generated will be described with reference to the flowchart of FIG.
It is in a standby state at step # R1 until a planned exit request unit 10 or an emergency exit request unit 11 issues a exit request from the first floor unloading port. When an operator issues a planned exit request by pressing the planned exit button or when an operator issues an emergency exit request by pressing the emergency exit button, a plurality of presets are set in accordance with those exit requests. Delivery control is started in order to deliver the specified number of lamps L for each type. The flowchart of FIG. 10 shows a process for a certain type of lamp L out of the 20 types of lamps L that are targeted for exit in the exit request. In addition, since the lamp L delivered by the delivery control is delivered in units of the container 4, more lamps L than the number requested by the delivery request may be delivered.

  When the exit request is generated, the process proceeds to step # R2, and the lamp classification of the exit lamp L is determined. If the lamp L to be delivered is a normal lamp, the process proceeds to step # R6. When the lamp L targeted for delivery is an emergency lamp, the process proceeds to step # R3.

  In Step # R3, in order to secure the minimum inventory quantity as the inventory quantity of the emergency lamp in the first zone Z1, the minimum inventory in order from the new receipt date to the lamp L of the type in the first zone Z1. Out of the storage units 3, a storage prohibition storage unit that prohibits delivery allocation is set until the number can be secured. In Step # R4, in order to secure the minimum stock quantity as the stock in the storage section 1 of the lamp L of the type to be delivered, if a delivery prohibition storage section corresponding to the minimum stock quantity can be secured in the first zone Z1. The process proceeds to step # R6. If the storage prohibition storage unit corresponding to the minimum stock quantity cannot be secured in the first zone Z1, the storage prohibition storage unit is expanded and set also in the second zone Z2 in step # R5. In other words, in order from the newest warehousing date for the lamp L in the second zone Z2, the banned storage unit until the sum of the number of the banned storage units set in the first zone Z1 corresponds to the minimum stock quantity. Set.

  In the first zone Z1 or in the first zone Z1 and the second zone Z2, when a storage-prohibited storage unit corresponding to the minimum stock quantity can be secured, in step # R6, out of the storage units 3 in the storage unit 1 is prohibited. For the lamp L stored in the storage unit 3 that is not set in the storage unit, the container 4 is selected so as to be equal to or more than the output quantity in order from the oldest storage date.

  In step # R7, it is checked whether or not the total number of the lamps L accommodated in the container that has been selected as a delivery target is sufficient for the delivery quantity. If it is sufficient, the process proceeds to step # R12. If it is not enough for the delivery quantity, the process proceeds to step # R8.

  In step # R8, it is determined whether the current shipping request is a planned shipping request or an emergency shipping request. This determination is made based on the stored output request type information by storing the output request type in the storage unit of the inventory management apparatus C when the output request is generated. If the current delivery request is a planned delivery request, the process proceeds to step # R9 to notify the worker by displaying missing part information on a display or the like.

  If the current delivery request is an emergency delivery request, the process proceeds to step # R10, and the prohibition setting for the storage unit 3 set as the prohibited storage unit is canceled. In step # R11, among the lamps L stored in the first zone Z1, the date of receipt for the lamp L stored in the storage unit 3 that is not selected because it was a prohibited storage unit. The containers are selected so that the shortage is satisfied in order from the oldest.

  As described above, when the exit request from the first floor exit is an emergency exit request, the process branches at step # R8. However, in the exit control based on the emergency exit request generated in an emergency, the stock in the first zone Z1 is Even if the inventory quantity in the first zone Z1 is reduced below the minimum inventory quantity in an emergency, the first type lamp L1 to the fifth type lamp L5 that are emergency lamps can be quickly Preventing issues and shortages. Even for an emergency exit request, the procedure for the normal lamp is the same as the normal lamp processing for the planned exit request.

  In this way, when the container 4 that accommodates the lamp L to be dealt with is selected, in step # R12, the container 4 that accommodates the selected lamp L for the type to be processed is accommodated. A delivery instruction for delivery of the container 4 to the delivery port is output from the unit 3.

  When the processing shown in the flowchart of FIG. 10 as described above is processed for all types to be shipped, and when a delivery command for delivery for each type is instructed, the delivery control for the delivery request ends.

  Taking the first type lamp L1 as an example, the fluctuation of inventory in the storage unit 1 will be described. As shown in FIG. 7, the first type lamp L1 has a minimum inventory quantity of “50” and a maximum inventory quantity of “80”. Therefore, the stock quantity of the first type lamp L1 in the first zone Z1 varies between “50” and “80” as shown in FIG. In addition, since the planned number of first type lamps L1 is “40”, “40” first type lamps L1 are issued based on the planned issue request. However, since the maximum number of stocks in the first zone Z1 is “80”, if “40” is issued from the stock in the first zone Z1, the stock in the first zone Z1 becomes “40” and the minimum stock. The number falls below "50". Therefore, among the “40” issued quantity according to the planned issue request, the remaining inventory that secures “50” which is the minimum inventory quantity in the first zone Z1 is issued, and “40” issued according to the planned issue request. The shortage with respect to the quantity is issued from the stock in the second zone Z2. Thus, when “40” first-type lamps L1 are issued from the storage unit 1 in accordance with the planned delivery request, the storage unit 1 uses both the delivery from the first zone Z1 and the delivery from the second zone Z2. The necessary number of first type lamps L1 are delivered. As a result, the minimum inventory quantity “50” can be secured as the inventory of the first type lamp L1 in the first zone Z1. In addition, since inventory is delivered in order from the oldest one at the time of entry in both delivery from the first zone Z1 and delivery from the second zone Z2, the stock secured in the first zone Z1 may deteriorate over time. Can be prevented. In FIG. 7, the total inventory number of the first type lamp L1 does not exceed “100”, but when the inventory quantity in the second zone Z2 is large, the total inventory quantity may exceed “100”.

  As described above, the warehousing control accompanying the warehousing request from the light distribution room on the third floor is performed in a distributed manner as the maintenance work progresses, and the warehousing control accompanying the planned warehousing request from the first floor unloading port is performed. Done regularly and intensively. Therefore, the stock of the lamp L in the storage unit 1 varies due to the storage of the lamp L with respect to the storage unit 1 and the delivery of the lamp L from the storage unit 1. In the lamp storage facility of the present embodiment, the first zone Z1 is configured such that the inventory of the minimum stock quantity avoids aging deterioration for any of the first type lamp L1 to the fifth type lamp L5 which are emergency lamps. Therefore, even if an emergency situation suddenly occurs, the necessary number of stocks that have not deteriorated over time can be properly issued for all types of multiple types of emergency lighting devices. Moreover, since the first zone Z1 is set in a low area of the storage unit 1, the storage of the lamp L with respect to the storage unit 1 cannot be performed automatically due to a power failure or a failure of the transport device. However, the emergency lamp can be taken out from the storage unit 1 by the manual operation of the worker, and the inconvenience in the event of a disaster or the like is reduced.
