Conventionally, this type of water treatment chemical is generally enclosed in a container such as a plastic bag or a cardboard case, delivered from the factory to the water treatment facility site, and transferred to a predetermined storage tank. Containers (plastic bags and cardboard cases) used for water treatment chemical delivery are discarded as used.
[0003]
On the other hand, in order to reduce the amount of discarded containers and save resources, it has been proposed to use the containers that can be used repeatedly (returnable containers) to realize the supply of the water treatment chemicals described above. Such a container is called, for example, an eco-shuttle (ECO SHUTLE; a registered trademark of Kurita Kogyo Co., Ltd.), and has attracted attention as an environmentally friendly chemical supply system.
[0004]
[Problems to be solved by the invention]
However, even if a container for supplying water treatment chemicals can be used repeatedly, the container cannot be reused unless the container filled with the chemical solution and delivered to the customer is recovered from the customer. . However, there are various usage conditions of chemicals at customers, and therefore it is difficult to periodically collect containers delivered to customers. On the other hand, if the containers are not collected smoothly, a large number of containers that have been used by customers are accumulated, which hinders effective use of the containers. In addition, depending on the frequency of collection of containers from customers and the number of collections per time, there is a problem that the collection cost increases.
[0005]
The present invention has been made in view of such circumstances, and its purpose is to efficiently collect and reuse containers filled with chemicals and delivered to customers. Another object of the present invention is to provide a chemical supply management system capable of suppressing the container collection cost and improving the container utilization efficiency (reuse efficiency).
[0006]
[Means for Solving the Problems]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a chemical supply management system according to an embodiment of the present invention will be described with reference to the drawings.
In addition, water treatment chemicals such as slime remover and scale inhibitor used in water treatment facilities can be reused for customers equipped with various water treatment facilities such as cooling water systems and boiler water systems. A case will be described as an example in which a chemical supply service is provided in which a container (returnable container) is filled and delivered, and a used container is collected from the customer and reused.
[0012]
FIG. 1 is a diagram showing a schematic configuration of a chemical liquid supply management system according to this embodiment, where 1 (1a, 1b, ˜1n) is a plurality of customers 2 (2a, 2b) equipped with water treatment facilities. , ˜2 m) are a chemical factory for producing water treatment chemicals used in each customer (water treatment facility) 1 and a chemical warehouse for storing chemicals. Reference numeral 3 denotes a sales office that forms a contact point (sales office) with the customer 1 in accordance with the location of each customer 1.
[0013]
By the way, in this system, the sales office 3 receives a water treatment chemical delivery request from the customer 1 and notifies the management center 4 of the received order information, and the management center 4 manages it through a predetermined transport company 5. It is constructed so that the water treatment chemicals requested to be delivered from each chemical factory 2 to each customer 1 are filled in a predetermined returnable container and delivered (chemical delivery processing). Also, in this system, the sales office 3 receives the container collection request from the customer 1 and notifies the management center 4 of the collection request information, and the customer is passed through the shipping company 5 under the management of the management center 4. The used container is collected from the tip 1 and is constructed so as to be returned to, for example, the nearest chemical factory 2 (container collection process).
[0014]
The returnable container A used for the delivery of water treatment chemicals is made of polyethylene having a width of 340 mm, a height of 350 mm and a depth of 250 mm, as shown in FIG. 2, for example, and a handle B is integrally formed on the top thereof. Has been. An injection / discharge port C is provided on the shoulder of the container A, and a sealing cap D is screwed onto the injection / discharge port C.
[0015]
Further, for example, a label sheet E on which a product name such as a water treatment chemical filled in the container A, a handling precaution thereof, and the like is attached is attached to the side surface of the container A. Further, on the upper part of the side surface of the container A, the date of manufacture of the container A, a container code unique to the container A (container ID code), and a standard code indicating the capacity and the like are recorded so as to be readable from the outside. A label portion F is provided.
[0016]
The label portion F represents information such as the manufacturing date and the container code described above as, for example, a QR code (quick response two-dimensional code), and is recorded directly on the outer surface of the container A by laser printing. . By the way, according to the label part (QR code) F provided in the container A in this way, there is no problem such as discoloration or peeling of printing ink, and even if about 30% of the whole is damaged, the recorded contents There is an advantage that reading is possible, which is suitable for managing the usage status of the container A that is repeatedly used.
[0017]
Now, in the system constructed as described above, the management center 4 that manages the chemical delivery process and the container recovery process to realize the chemical supply service is the name of the plurality of customers 1 (1a, 1b, .about.1n). A database (DB) 6 in which (identification name) and route information obtained by classifying the location of the customer 1 by route are associated and registered. For example, as shown in FIG. 3, this database (DB) 6 stores customer information including [name], [address], [telephone number], [person in charge], and [route] of the customer 1 with the service contents. Are registered in advance. In addition, in the database 6, information on [water treatment chemical name] and [order date] related to the water treatment chemical received from the customer (for which a delivery request has been received) is registered along with each customer information. Further, as will be described later, the number of containers shipped and filled with the water treatment chemical to the customer 1 and the number of containers collected from the customer 1 [ The number of containers collected] is registered.
[0018]
In addition, the said route information classifies the customer 1 which the transportation company 5 can visit by one operation | movement, for example according to the location (address) of the customer 1, for example, becomes "XX district". Given as information. The service contents are classified according to the type of chemical solution (water treatment chemical) supplied to the customer 1 and the number of delivery requests. Therefore, even when the same customer 1 supplies a plurality of types of water treatment chemicals or when water treatment chemicals are supplied more than once, the database 6 stores the types of water treatment chemicals and their delivery. They are sequentially registered as separate management items according to the number of times.
[0019]
When the management center 4 receives a water treatment chemical delivery request from the customer 1 through the sales office 3 described above, the management center 4 registers the delivery request information in the database 6 as will be described later. In response, a delivery command is issued to the shipping company 5. Then, the shipping company 5 delivers a predetermined number of containers filled with water treatment chemicals from the predetermined chemical factory 2 to the customer 1 in accordance with the delivery instruction (command content). The management center 4 issues a container collection command to the shipping company 5 with reference to the database 6 when there is a collection request for used containers from the customer 1 through the sales office 3 described above. Then, the shipping company 5 collects the container from the customer 1 in accordance with the above collection command (command content) and returns it to the nearest chemical factory 2, for example.
[0020]
The water treatment chemical delivery process executed under the management of the management center 4 will be described in detail. FIG. 4 shows the concept of the delivery process, and FIG. 5 shows the schematic process procedure. If the customer 1 receives a request for delivery of water treatment chemicals from the customer office 3 (step S1), the customer office 1 that has received the delivery request accesses the management center 4 from the communication terminal, for example. The customer information and order information indicating the type and amount of the chemical are input (step S2). By this input process, the [name] and [water treatment chemical name] of the customer 1 in the database 6 are designated, and the [order date] and [the number of containers shipped] are registered. This order information registration process is performed every time there is a chemical delivery request from the customer 1.
[0021]
Then, the management center 4 refers to the database 6 every 11:00 am on the business day, for example, acquires information on the customer 1 who requested the delivery of the chemical solution, and the type of the requested chemical solution and the number of shipments thereof. Information is obtained, and first, a chemical solution delivery command is issued to the chemical factory or chemical warehouse 2 (step S3). That is, since the types of chemicals manufactured by the chemical factory 2 are generally different, the management center 4 defines the chemical factory (chemicals warehouse) 2 to which the chemicals should be shipped according to the type of chemical requested for delivery. The decision is made, and the number of shipped containers filled with the chemical solution and information on the delivery destination (customer) are notified to the chemical factory (chemical warehouse) 2.
[0022]
Further, the management center 4 determines to which shipping company 5 the delivery of the chemical solution to the customer 1 is entrusted according to the route information of the customer 1. Then, a shipping list is created for each route, and a delivery request for the chemical solution (container) is issued to the delivery company 5 (step S4). This shipping list is made up of chemical solution shipment information for each route that indicates how many containers filled with chemical solutions are delivered from which chemical factory 2 to which customer 1.
[0023]
The delivery instruction performed in this manner may notify the shipping company (shipping list) to the shipping company 5 and the chemical factory 2 using a FAX or the like. You may make it notify as what is called computer screen information via the communication network which connects the factory (chemical | medical agent warehouse) 2. FIG. On the contrary, the management center 4 may be accessed periodically from the transport company 5 or the chemical factory (chemical warehouse) 2 side, and the shipment slip (shipment list) constructed on the database 6 may be read out.
[0024]
Then, in the drug factory (medicine warehouse) 2 that has received the shipping slip, the designated number of containers filled with the drug to be shipped to the customer 1 are prepared. A specified number of containers filled with the medicine are delivered to the customer 1 (step S5). Thus, a series of chemical solution supply services from acceptance of a chemical solution delivery request to delivery of the chemical solution is completed. In the database 6, a record of how many chemical solutions are filled in a container for which customer 1 and how many bottles are shipped (the number of containers shipped) is left.
[0025]
On the other hand, the collection processing of the used container from the customer 1 is executed, for example, as shown in FIG. 6 with the concept of the collection and delivery processing and with the schematic processing procedure shown in FIG. That is, when a request for collecting used containers is issued from the customer 1 to the sales office 3 (step S11), the sales office 3 that receives the collection request accesses the management center 4 from the communication terminal, for example. The customer information and collection information indicating the number of containers collected are input (step S12). By this input process, the [name] of the customer 1 in the database 6 is designated, and the [number of containers collected] is registered. This collection process of the collection information is performed every time there is a container collection request from the customer 1.
[0026]
Then, the management center 4 refers to the database 6 every 11:00 am on business days, for example, and obtains route information by using the name of the customer who requested the container collection as a clue. 1 is classified. At the same time, according to the route information, the drug factory (medicine warehouse) 2 from which the container is collected is determined as the chemical factory (medicine warehouse) 2 closest to the route (step S13). Then, the container collection list obtained for each route is notified to the shipping company 5 and the container collection operation is entrusted (step S14). As a result, the shipping company 5 collects the used containers from the customer 1 according to the container collection list, and returns the containers to the designated chemical factory (chemical warehouse) 2 as described above.
[0027]
Then, in the drug factory (medicine warehouse) 2 that receives the containers collected by the shipping company 5, the number of containers collected from each customer 1 is confirmed, and the number of containers collected for each customer 1 as the collection source. Is registered in the database 6 (step S16). The collection number is registered in the database 6 with reference to, for example, the number of containers shipped registered in the database 6. Specifically, when there are a plurality of management items for a certain customer 1, the collection number is recorded in order from the management item with the oldest date according to the order date information registered in the database 6.
At this time, if the collected number of containers collected at one time exceeds the shipped number of each management item in the database 6, the collected number is recorded up to the shipped number, and the remaining collected number is managed next. What is necessary is just to record sequentially as the collection | recovery number of items.
[0028]
On the other hand, the management center 4 periodically checks the recorded contents of the database 6 and totals the number of shipped containers and the number of collected containers for each customer 1. Then, as shown in a schematic processing procedure in FIG. 8, the number of containers remaining in the customer 1 is calculated by obtaining, for example, the difference from the number of shipments and the number of collections (step S21). . Then, the management threshold value set in advance is compared with the number of containers left at the customer 1 to determine whether or not the number of containers left at the customer 1 is abnormally large (step S22). ). Then, in order to call attention to the customer 1 whose container collection efficiency is poor, the fact is notified to the sales office 3 in charge of the customer 1 (step S23).
[0029]
Specifically, for example, the number of containers delivered to customer 1 in units of one month (shipment number) and the number of containers collected from customer 1 during that month (recovery number) are examined. The collection efficiency of containers from customer 1
[Recovery efficiency] = [Recovered quantity] / [Shipped quantity]
Evaluate as If the collection efficiency exceeds a predetermined threshold, it is determined that there are a large number of containers left unnecessarily at the customer 1 and a warning is issued to prompt the collection.
[0030]
Thus, according to the above-described embodiment, the container 1 is filled with the water treatment chemical in response to the request from the customer 1 and delivered, and then the container ( When the empty container is collected from the customer 1 and reused, the management center 4 manages the number of shipped containers and the number of collected containers for each customer 1, so that the customer 1 can easily manage for a long time. If an empty container is left unattended, recovery of the container can be promoted. And it becomes possible to raise the collection efficiency of a container and to raise the efficiency which reuses this container.
[0031]
Moreover, according to the system mentioned above, since the container filled with this chemical | medical solution can be delivered to the customer 1 who requested delivery of a chemical | medical solution according to a route, the delivery efficiency can be improved. In addition, since the containers collected from the customer 1 by route are only returned to the nearest chemical solution factory 2, there is no need to classify the collection containers according to the container shipping source at the time of supplying the chemical solution, and the collection work is easy. Etc. are produced.
[0032]
The present invention is not limited to the embodiment described above. For example, the chemical liquid supply process and the container recovery process may be performed in an integrated manner, and an empty container existing at the chemical liquid supply destination (customer 1) may be recovered on the spot. In addition, the number of containers shipped to customer 1, the number of containers collected from customer 1, and the number of containers remaining in customer 1 are obtained in a list, and the usage status of the containers You may make it grasp.
In addition, the present invention can be variously modified and implemented without departing from the scope of the invention.
[0033]
【The invention's effect】
As described above, according to the present invention, when a chemical solution is filled in a predetermined container and delivered to a customer, and a chemical solution supply service for collecting and reusing a used container from the customer is realized, Delivery of the chemical solution to the customer and recovery of the container from the customer can be performed efficiently. In addition, the number of containers shipped and the number of containers collected can be used to ascertain how chemicals are used at customers, and the number of containers remaining at customers can be managed to facilitate the collection and reuse of containers. There are many practical effects such as an increase in efficiency.
[0034]
In particular, under the unified management in the management center using the database, the customer management and the container management can be easily performed in a unified manner.
