  Previously, the inventory status of the linen room on the customer side (user side) was managed so that there was no shortage of products on the customer side, but the product quantity on the customer side was the factory side (supply side) However, it was not possible to grasp the situation, and it was necessary to stock the stock much larger than the minimum necessary amount. However, it is not realistic to introduce a management system on the customer side and request management work from the customer. Currently, the inventory is adjusted by going to the customer side and performing inventory work manually.

  On the other hand, as disclosed in Patent Documents 1 and 2, attaching a tag such as an IC to each linen has a problem of high introduction cost and high operational load. In particular, it is difficult to prevent the loss of towels and towels, but the management cost becomes higher if the loss is assumed.

Also, in the linen supply industry, the total amount of linen is reduced because it is not exchanged by the number of times of use, but it is disposed of on the customer side when dirt that cannot be cleaned is attached or when hazardous materials are attached. There is an industry-specific problem that it cannot be accurately grasped.
In addition, when production is performed in parallel in a plurality of facilities (each facility may be separated), it is difficult to manage the number of shipments and the number of collections.

  An object of the present invention is to provide a distribution management system that can manage the quantity of linens distributed to customers without attaching an IC tag or the like to reuse products such as linens.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the distribution management system which can manage the quantity of the reuse product currently distribute | circulated to the customer side, without attaching IC tags etc. to reuse products, such as linens. That is, it is possible to provide a distribution management system for reuse products that is excellent in ease of introduction and has a low operational load.

The best mode for carrying out the present invention will be described with an example of a business in which a product is used in a guest room. Hereinafter, the product 7 and the used product 8 may be collectively referred to as linens.
FIG. 1 is a schematic diagram showing a business process of the system of the present invention. In the business to be systematized, the product 7 produced on the factory side is shipped to the customer side, the used product 8 used in the guest room 22 is collected, and the product 7 is shipped again. Yes. The location of the good box 6 (where to stay) is five, but since there are six locations where the product 7 is located (where to stay), these cycles are always shifted by one.
There is a clearing facility 3 and a warehouse 5 on the factory side. The production facility 3 collects the used product 8, washes it, dries it, and folds it into a product 7. The product 7 is packed in a good box 6 and stocked in the warehouse 3. A predetermined number of good boxes 6 are delivered from the factory side to the customer side by a transport vehicle 9 such as a truck.

There are a linen room 21 and a guest room 22 on the customer side. A predetermined number of good boxes 6 shipped from the factory side are stored in the linen room 21 as stock. On the customer side, the product 7 is used in the guest room 22 according to demand.
The driver of the transport vehicle 9 collects empty boxes 6 and used products 8 on the customer side when a predetermined number of boxes 6 are shipped. The collected used products 8 are stored again in the warehouse 5 as products 7 through the washing process, the drying process, and the folding process again in the production facility 3.
In addition, when stocking in the warehouse 5, you may put in the good box 6 and may stock on a shelf.

The distribution management system of the present invention is characterized by managing the quantity of linens by managing the good box 6. Although it is conceivable to manage each linen with a data tag or the like, since the cost is high and it is not practical, a good box 6 is used as a management unit. The contents of the cool box 6 are different from each other, and not only the type of linens but also the quantity may be different. Other varieties may be managed at the same time. For example, 10 yukatas and 10 belts are set as one management unit.
The good box 6 of the present invention is not limited to a physical good box, and may be any one as long as it indicates one management unit (unit) to be shipped and collected. That is, the “unit” does not have to be in the shape of a box. For example, a unit in which 10 sheets or 20 towels are bundled with a string and a storage medium (for example, a plate with a cord) is attached to the string. It is good also as.
The good box 6 is assigned a unique ID, and the state of the good box 6 is managed by the server 1. The good box 6 is provided with a storage medium such as a barcode or an IC tag, and the ID can be recognized by reading means such as a barcode reader. It may be provided with a rewritable label (rewrite card) that can display the expiration date, customer name, product name, etc. so that the stored information can be seen. At the time of shipment from the warehouse 5, the customer ID uniquely associated is associated. In the case of a customer-only product, customer information may be added during production.

When transport to the customer side is performed every day, the minimum required total product amount is about three times as much as the guest room usage. One unit quantity becomes the linen room inventory, one unit quantity becomes the room usage, and one unit quantity becomes the production. In general, keep more than three times the amount of room use in anticipation of safety.
Some products have a replacement cycle of about once a week (for example, a table cloth). Depending on the type of product, the collection frequency and total product amount are appropriately determined.

  By the way, the products supplied to the customer side are roughly classified into common products and dedicated products. The common product is a product used by a plurality of customers, such as a towel or towel. A dedicated product is a product that is used only by a specific customer, such as a table cloth or uniform. In the case of common products, the inventory quantity in the linen room is important, and in the case of dedicated products, it is important to grasp the total amount of products.

FIG. 2 is a schematic diagram showing the configuration of the system of the present invention. A server 1 is installed on the factory side, and various types of data such as the type and quantity of linens, factory side information, customer side information, and the like are stored. The server 1 is connected to the collection terminal 11, the production terminal 12, and the shipping terminal 13 through a network.
The collection terminal 11 manages the quantity of boxes 6 that have been collected in the production facility 3. The quantity of the product registered in the collected good box 6 is set as the quantity (approximate arrival number) of the used product 8 collected in the next cycle. This makes it possible to grasp the approximate number of arrivals in the next cycle.
The production terminal 12 manages data such as the quantity of the product 7 transferred from the production facility 3 to the warehouse 5 and the type and quantity of the product 7 stored therein. Further, the production terminal 12 issues a slip (may be an electronic slip) in which information such as customer, product type, and quantity is described.
The shipping terminal 13 manages the quantity of boxes 6 that may be delivered from the factory side to the customer side and the data of the products 7 stored therein.
The production terminal 12 is not an essential component, and the system can be operated if the collection terminal 11 is provided. When the production terminal 12 is not provided, a slip is issued by the shipping terminal.

The system of the present invention is based on the premise that linen is discarded or lost. On the customer side, for example, it is assumed that the guest is discarded when the guest is taken home or is so dirty that it cannot be removed even after washing. On the factory side, for example, it is assumed that if a certain level of dirt or tear is found in the linen during production, it will be discarded. According to the system of the present invention, it is possible to grasp the outline of the loss situation on the customer side by looking at the difference between the approximate arrival number and the production number. Product loss on the customer side is directly linked to a shortage of inventory on the customer side, so there is a great need to understand the product loss situation.
If the management unit (unit) is a good box unit, the upper limit of the error can be a good box unit. For example, if 20 towels are stored in a good box, the number of towels on the customer side can be grasped with an accuracy of ± 20 sheets. In order to keep the grasp accuracy within the storage capacity of a good box, it is necessary to avoid using products stored in a plurality of good boxes in parallel. There should always be one open, clean box containing the product. Preferably, a good box is managed by first-in first-out (FIFO). From the viewpoint of quality control, an expiration date may be provided from the time of washing or shipping to prompt the FIFO.

When the product 7 is delivered to the customer side, the empty box 6 is collected. The quantity of empty boxes 6 × storage amount (management quantity) is the maximum quantity of products 6 currently used in the guest room. Depending on the type of business on the customer side, if the visit cycle is constant, the quantity of the collected good box 6 x the amount of storage is an approximate value of the used product 8 collected at the next cycle visit (theoretical maximum value) ).
Since it is usually impossible to have the customer count the quantity of the used product 8 on the customer side and it is difficult to count the quantity on the factory side for reasons such as hygiene, the amount collected in the next cycle It is important to predict.

Depending on the usage status in the guest room 22, it is also assumed that the quantity of the used product 8 collected in the next cycle does not match the predicted quantity. However, even in this case, adjustment is made based on the stock quantity in the linen chamber 21, and the stock quantity in the linen chamber 21 can be kept within a certain range.
Insufficient inventory in the linen room 21 is fatal for the customer side, but having excessive inventory is not preferable from the viewpoint of quality. In the linen supply industry, it is important to sequentially rotate the linens while managing the number of stocks in the linen room 21 within a predetermined range. However, according to the present invention, this can be realized.

The operation cycle of linens in the system of the present invention will be described with a specific example with reference to FIGS.
As shown in FIG. 3, all products (total amount 700 points) are initially stored in a warehouse on the factory side. A square box in the warehouse is a box (data management unit) in which a product is stored, and a box surrounded by a double line indicates a plurality of boxes. The stock standard number of the linen room is 200, and one good box can accommodate 50 products.

  FIG. 4 shows a state in which a good box containing products for the number of stocks in the linen room 200 has been transferred from the warehouse to the linen room. A shipping terminal installed in the warehouse at the time of shipping the good box subtracts 200 points from the stock data of the warehouse, and adds 200 points to the stock data of one linen room associated with the ID of the good box.

FIG. 5 shows a state where the first delivery has been performed from the start of operation. Since the stock standard number of 200 is in the linen room, delivery is not performed in the first delivery. Empty good boxes equivalent to the use of guest rooms (100 points) are collected and transferred to production facilities by transport vehicles. In the production facility, it is expected that 100 used items will be collected next time when the collection terminal reads the ID attached to the good box.
The customer-side information grasped by the system is 100 points for the linen storage, 100 points for the guest room usage (in-process), and 200 customer-side totals.

FIG. 6 shows a state where the second delivery has been performed from the start of operation.
Since there are 100 in-processes in the previous cycle (FIG. 5), 100 products are transferred from the warehouse to the linen room by a transport vehicle. On the customer side, empty boxes equivalent to the use of the cabin (50 points) are collected and transferred to the production facility by a transport vehicle. Also, 100 used items are collected and transferred to production facilities by transport vehicles.
The empty box that can accommodate the 100 products collected first is in a pooled state and managed as an empty box that can be reused.
The customer-side information grasped by the system is 150 points for the linen storage, 50 points for the guest room usage (in-process), and 200 points for the customer side total.

FIG. 7 shows a state where the third delivery has been performed from the start of operation.
Since there are 50 work in progress in the previous cycle (FIG. 6), 50 products are transferred from the warehouse to the linen room by a transport vehicle. On the customer side, empty boxes equivalent to the use of the guest room (100 points) are collected and transferred to the production facility by a transport vehicle. Also, 50 used items are collected and transferred to production facilities by transport vehicles.
The 100 products produced in the production facility are stored in a pooled good box and transferred to a warehouse. At this time, information such as customer, product type, and quantity is registered by the production terminal.
Empty good boxes that can accommodate 50 products are in a pooled state and managed as reusable empty good boxes.
The customer-side information grasped by the system is 100 points for the linen storage, 100 points for the guest room usage (in-process), and 200 customer-side totals.
If the number of products produced above is less than 100, it is recorded as lost. Actually, the product is not lost, and it may be counted in the next cycle, so it is impossible to accurately grasp the total amount of the product instantaneously. It is possible to grasp the trend of change in quantity.

  As shown above, the system of the present invention makes it possible to predict the amount of used items to be collected next time by grasping the management quantity (accommodation amount) of empty empty boxes collected from the linen room, It is possible to grasp the distribution management of linens on the customer side and factory side in a timely manner. In addition, when linen consists of multiple items (for example, towels, sheets, yukata, etc.), the total amount of reuse products and / or the total management quantity of good boxes can be output for each item. It is preferable.

  Hereinafter, details of the present invention will be described by way of examples, but the present invention is not limited to the examples.

The system of the present embodiment is configured as shown in FIG. 2, and on the factory side, a server 1, a collection terminal 11, a production terminal 12, and a shipping terminal 13 are arranged connected to a network. The server 1 stores various data such as the type and quantity of linens, factory side information, and customer side information. The collection terminal 11, the production terminal 12, and the shipping terminal 13 are personal computers into which dedicated software is introduced, and are connected to a barcode reader for reading a barcode attached to a good box.
The good box 6 is given one ID, and the ID can be recognized by reading a barcode (unique code) attached to the outer surface of the good box 6. The database of the server 1 stores information such as the ID of a good box, the type / quantity of the stored product, the customer ID, the position attribute (distribution status), and the like.

  FIG. 8 shows an example of an inventory management screen of the system of this embodiment. On the screen of FIG. 8, it is possible to graphically grasp information such as the number of products distributed to customers, the number of products in the linen room, and the total amount of products distributed. By specifying a date on the left side of the screen in FIG. 8, it is possible to grasp product distribution information on the specified date. Also, by using the drop-down list on the left side of the screen, you can select one factory from multiple factories for inventory management, select one customer from multiple customers for inventory management, It is also possible to carry out inventory management by specifying a product type.

FIG. 9 is a screen showing an example of the amount of products by location in the system of this embodiment. The distribution of products in the production facility 3, the warehouse 5, the linen room 21, and the guest room 22 can be grasped graphically. In the graph shown on the left side of FIG. 9, the ratio of the quantities of “production”, “in use”, “linen quality”, and “warehouse” is shown in order from the top. The graph shown on the right side of FIG. 9 is an enlarged view of the vicinity of the upper limit of the graph on the left side of FIG. 9, and it can be confirmed that the total quantity of items is gradually decreasing.
The quantity in the production facility 3 and the quantity in the guest room 22 are calculated based on the information on the good box 6 grasped by the collection terminal 11 when the empty good box 6 is collected. That is, when the transport vehicle 9 collects the empty good box 6 from the customer, the management quantity (a1) of the good box 6 read by the recovery terminal 11 is set as the quantity of the guest room 22, and the next empty from the customer may be used. When the box 6 is collected, the management quantity (a2) of the good box 6 read by the collection terminal 11 is set as the quantity of the guest room 22, and the quantity (a1) of the empty good box 6 for the previous time is set in the production facility 3. Estimated quantity. (In fact, it is grasped in the production volume.)
The quantity in the warehouse 5 is calculated based on the quantity of the product 7 grasped by the production terminal 12 when the product 7 is transferred to the warehouse 5. The quantity in the linen room 21 is calculated based on the quantity of the product 7 grasped by the shipping terminal 13 when the product 7 is shipped from the warehouse 5.

The database provided in the server 1 of this embodiment can be queried by SQL, and the position attribute associated with a good box ID is displaced by a query from each terminal. The position attributes are as follows: 1 is the linen in the warehouse, 2 is the shipping state, 4 is in the linen room, 8 is in the cabin, 16 is in the collection state, 32 is in the production state, and 0 is a good box The stored state and setting can be exemplified.
In position 1, the start date is the production date on the date of production processing, and the end date is managed as undetermined. At position 4, the start date (current day or next route visit date) is registered at the time of shipment, and the end date is managed as undecided. At position 8, the start date is set at the time of collection registration from empty box collection, and the next route visit date is set as the end date. At the same time, position 32 is processed, the next route visit date is set as the start date, and the next next route visit date is set as the end date. (This is set in advance as the distribution remaining period based on the route information when empty boxes are collected because there is no means for following the data.)
It is possible to grasp the location and quantity by inquiring the data managed as described above with the position attribute, date, and the like. It should be noted that there is no double period in each position.
Incidentally, although it is theoretically possible to reproduce the above distribution management manually, the situation of the route (designated day of the week) is not uniform, so it is difficult to manage the quantity calculation in a timely manner, and in fact. Is not feasible.

Conventionally, in the linen supply industry, it has been necessary to stop the distribution and check the inventory of the linen room on the customer side, mainly for customers with many deliveries. In this regard, according to the system of the present embodiment, it is possible to grasp the quantity in the production facility 3 and the quantity in the guest room 22 based on the information of the empty box 6 without stopping the distribution. The amount of linen in each factory side can be grasped.
Moreover, it is not necessary to attach a tag to each point of the product 7, and it is not necessary to provide special equipment on the customer side. Therefore, it is easy to introduce, has a low operational load, and is very practical. be able to.

  INDUSTRIAL APPLICABILITY The present invention is suitable for distribution management in a rental business of reused products that have a low unit price and are premised on disposal and loss. Beer bottles, cleaning tools, footwear, sterilized medical tags and other IC tags, etc. can be used, and it is possible to manage low-cost reuse products that do not match the installation of a management terminal on site. It becomes.
