Description

  The present invention relates to a vending machine reuse system for reusing a vending machine to be discarded.

  In recent years, industrial products have been reused and recycled for consideration of the global environment and cost reduction. There are various types of industrial products, but vending machines are one of those that are easy to reuse because the disposal route is almost fixed.

  Vending machines may be discarded not only when they can no longer be used due to breakdowns, but also when conditions such as the age of installation are met. In such a case, some of the units (housing units) constituting the parts and the housing can be reused. Therefore, the following systems have been proposed in order to efficiently reuse these components and housing units.

  For example, in Patent Document 1, the usage time and the remaining life are calculated for each predetermined period in consideration of the usage conditions of each component of the vending machine, the calculated usage time and the remaining life, the part name, the use A system for storing the component information including the start date and the theoretical lifetime, and a unit for providing the stored component information to an administrator of the vending machine, the system managing the lifetime of the component It is disclosed.

  In the system of Patent Document 1, since the life of each component of the vending machine can be managed, the remaining life of the component of the vending machine to be discarded can be grasped, so that each component can be reused. It is possible to reduce the man-hours for checking whether or not.

  Further, the cited document 2 includes a database management device that manages a database that stores component information related to parts of a vending machine, and a plurality of terminal devices that acquire the component information stored in the database from the database management device. The database includes identification data for identifying a part of the vending machine, history data indicating a usage history of the part, storage place data indicating a storage place of the part, and the terminal device from the storage place The terminal device has input means for inputting condition data indicating a desired condition of the target component, and the database management device. Receiving means for receiving the identification data, the history data, and the transportation fee data of a plurality of parts, and a plurality received by the receiving means The part history data and the condition data input by the input means are compared to select a plurality of reusable parts, and the parts identification data to be reused based on the transportation fee data corresponding to the selected parts And a specifying means for specifying

  In the system of the cited document 2, reusable parts can be automatically specified in consideration of transportation charges, and thus reusable parts can be supplied for manufacturing a new vending machine. .

JP 2003-217209 A Japanese Patent Laid-Open No. 2003-256591

  As described above, since the remaining life of parts can be managed in the system of Patent Document 1, the man-hour for checking whether or not the parts taken out from the vending machine scheduled to be discarded can be reused is reduced. can do. Moreover, in the system of patent document 2, the reuse part used for manufacture of a new vending machine can be selected from the reuse parts currently stocked from a viewpoint of optimizing a transportation fee.

  However, these systems can be applied to the reuse of parts, but cannot be used to efficiently reuse a housing unit, in particular, a housing unit including a component unit.

  In view of the above problems, an object of the present invention is to provide a vending machine reuse system that efficiently reuses a casing unit of a vending machine including a component unit.

  In order to solve the above-described problems, the vending machine reuse system according to the present invention is configured to determine whether or not each of a plurality of casing units constituting a casing of a vending machine to be discarded can be reused, and the casing unit. The disposal vending machine database that records the evaluation value of the appropriateness of the reuse of the component units that constitute the component unit, and is necessary for using the component unit acquired from the vending machine scheduled to be discarded for each of the component units. Reuse based on the part unit database that records the amount of money and the amount necessary to use the new part unit, the contents recorded in the disposal vending machine database, and the contents recorded in the part unit database The vending machine is configured so that the amount of money required for assembling the vending machine by combining the possible housing units is minimized under predetermined conditions. And a, and reuse machine determination unit for determining a vending machine of the waste will acquire the housing unit reusable constituting the machine.

  In this configuration, since the disposal vending machine database records whether or not the casing unit constituting the casing of the vending machine can be reused, a new vending machine is manufactured based on this information. It is possible to determine from which vending machine to take out each housing part for the purpose. The disposal vending machine database also records reusability, that is, the quality of each component unit included in the housing unit. On the other hand, in the parts unit database, the cost for reusing the part unit acquired from the database to be discarded, for example, the cost for removal, maintenance, installation, etc. and the cost for using the new part unit, for example, The price of new parts unit, installation cost, etc. are recorded. Based on this information, the reusable machine determination unit acquires each casing unit from the vending machine to be discarded, and the total cost for manufacturing a new vending machine is minimized under a predetermined condition. Thus, the vending machine to be reused, that is, the vending machine from which each casing unit is acquired is determined. The predetermined condition of the present invention is a concept including unconditional.

  As described above, when the vending machine reuse system according to the present invention is used, it is automatically determined which vending machine each housing unit should be acquired from, so the vending machine can be efficiently reused. be able to. Further, since the vending machine to be reused minimizes the cost under a predetermined condition, the manufacturing cost can be suppressed.

  Vending machines to be discarded are not collected at one place, but are collected at a plurality of collection bases and then transferred to a production base where the casing unit may be reused. In such a case, it is necessary to consider the transfer cost of the vending machine in order to reuse the housing unit. Therefore, in one preferred embodiment of the reuse system of the vending machine according to the present invention, the vending machines to be discarded are integrated at a plurality of integration bases, and the vending machines to be discarded are integrated. A transfer cost database for recording a transfer amount from an accumulation site to an assembly site where assembly is performed, and the reusable machine determination unit further includes the housing based on the transfer amount recorded in the transfer cost database. Find a combination of body units.

  In this configuration, it is possible to determine the vending machine to be reused in consideration of the transfer cost from each accumulation base to the base where the vending machine is assembled (manufactured).

It is the schematic of the reuse mechanism of the vending machine of this invention. It is a figure showing the structure and functional block of the reuse system of the vending machine of this invention. It is a flowchart showing the flow of a process of the reuse system of the vending machine of this invention. It is an example of a disposal vending machine database. It is an example of the database schema of a component unit database. It is a flowchart showing the flow of acquisition processing of component unit information.

  The vending machine according to the present invention includes a plurality of housing units, and at least one of the housing units includes a component unit. In the present embodiment, the housing unit is a main body and a door. Also, the door as the housing unit is a design unit (front), design unit (back), sales promotion unit (front), sales promotion unit (back), outlet unit, customer service unit, heat insulation unit (upper). , Insulated unit (bottom).

  In the vending machine reuse system according to the present invention, when such a vending machine is discarded, a reusable casing unit (main body and door) is removed from each vending machine, and they are combined to form a new one. In order to assemble (manufacture) the vending machine, the vending machine that acquires each casing unit is determined.

  FIG. 1 is a schematic diagram of the mechanism of reuse of a vending machine according to the present invention. As shown in the figure, the vending machines V to be discarded are collected at a base called maintenance base B (an example of the base of the present invention). Although only two maintenance bases B1 and B2 are shown in the figure, the number of maintenance bases B can be changed as appropriate. In the following description, when it is not necessary to distinguish between the maintenance bases B1 and B2, they are collectively referred to as the maintenance base B.

  When the vending machines to be discarded are accumulated at the maintenance base B, whether or not each casing unit can be reused and the suitability for reuse of the component units is determined artificially, and the automatic disposal is performed together with the vending machine identification information. Registered in the vending machine database D1.

  In the present embodiment, the reuse of the vending machine, that is, the manufacture of a new vending machine by combining the casing units taken out from the discarded vending machine is performed at a base called a reuse center A. Therefore, the reuse system of the vending machine is used at the reuse center A.

  In the reuse center A, a vending machine that acquires each casing unit is determined from the vending machines registered in the disposal vending machine database D1, using a vending machine reuse system. Then, each maintenance base B is instructed to transfer the determined vending machine, the housing unit is acquired (removed) from the transferred vending machine, and a new vending machine is manufactured by combining them. .

  FIG. 2 is a diagram illustrating a system configuration and each functional unit of a vending machine reuse system according to the present embodiment. As shown in the figure, each maintenance base B is provided with a terminal T constituted by a general-purpose computer. The terminal T can access the disposal vending machine database D1, the parts unit database D2, and the transfer cost database D3 via the network N.

  The disposal vending machine database D1 is composed of a non-volatile storage medium such as a data base management system (DBMS) and a hard disk, and as described above, the model number and identification information of the disposal vending machines accumulated at the maintenance base. And whether or not each casing unit of the vending machine can be reused and the suitability for reuse of each component unit are recorded in association with each other. Note that the vending machine identification information uses information that can uniquely identify each vending machine, such as the machine number of the vending machine. Further, in this embodiment, whether or not a housing unit can be reused is a binary value that indicates whether reuse is possible or not, and the suitability for reuse of a component unit is in five stages A to E. Here, A to D can be reused, and E represents that reuse is impossible. In addition, A to D represent the degree of maintenance required for reuse. For example, A represents that reuse is possible without maintenance.

  As will be described later, the component unit database D2 records costs necessary for reusing a component unit and costs for using a new component unit.

  The transfer cost database D3 records a cost required for transferring the vending machine from each maintenance base B to the reuse center A, as will be described later.

  In this embodiment, the disposal vending machine database D1, the parts unit database D2, and the transfer cost database D3 are installed at a base other than the maintenance base B and the reuse center A. Alternatively, it may be installed in the reuse center A. These may be managed by one DBMS.

  The vending machine reuse system of the present embodiment is configured by a general-purpose computer, and includes a condition acquisition unit 11, an information acquisition unit 12, a reusable machine determination unit 13, and a transfer instruction unit 14, as shown in the figure. Yes. In the present embodiment, these functional units are configured by cooperation of the CPU and software, but may be configured only by hardware.

  The condition acquisition unit 11 acquires various conditions for operating the vending machine reuse system input to the terminal T. The conditions in the present embodiment determine the extraction condition for extracting (narrowing) vending machines to be reused and the vending machine for acquiring the casing unit from the vending machine to be reused. Conditions (hereinafter referred to as determination conditions, which are examples of the predetermined conditions of the present invention). The acquired conditions are sent to the information acquisition unit 12 and the reuse machine determination unit 13.

  The information acquisition unit 12 acquires necessary information by accessing each database. For example, vending machine information that matches the conditions such as the model number of the vending machine included in the conditions acquired by the condition acquisition unit 11 is acquired from the disposal vending machine database D1. Further, information on the parts unit mounted in each vending machine and information on the transfer cost from each maintenance base B are acquired from the part unit database D2 and the transfer cost database D3. The acquired information is sent to the reuse machine determination unit 13.

  Based on the condition acquired by the condition acquisition unit 11 and the information acquired by the information acquisition unit 12, the reusable machine determination unit 13 determines a vending machine that acquires a casing unit to be reused. At this time, the reuse machine determination unit 13 determines the vending machine from which each casing unit is acquired so that the manufacturing cost of the vending machine is reduced under a predetermined condition. The determined vending machine information is sent to the transfer instruction unit 14.

  The transfer instruction unit 14 that has acquired the information on the vending machine determined by the reusable machine determination unit 13 instructs the maintenance base B in which the vending machines are integrated to transfer the vending machine.

  FIG. 3 is a flowchart showing the processing flow of the vending machine reuse system of the present invention. Prior to this processing, at each maintenance site B, when a vending machine to be discarded is brought in, the worker determines whether the main body and the door as a housing unit can be reused, The reusability of each component unit described above is determined (hereinafter, these determination processes are referred to as pre-checks). An operator or the like operates the terminal T at each maintenance site B and inputs the results of these pre-checks into the disposal vending machine database D1. The disposal vending machine database D1 of this embodiment records the model number, machine number (identification information) and precheck result of the vending machine as well as the precheck date, manufacturer, and year. Yes.

  FIG. 4 is an example of information recorded in the disposal vending machine database D1. As shown in the figure, the disposal vending machine database D1 of the present embodiment is composed of two tables and is associated with the machine number. The table of FIG. 4A records the machine number, model number, manufacturer, year, pre-check date of the vending machine, and identification information of the maintenance base B where the vending machine is integrated. On the other hand, the machine number of the vending machine and the pre-check result are recorded in the table of FIG.

  First, an operator or the like operates the terminal T installed in the reuse center A to input extraction conditions and determination conditions, and the input conditions are acquired by the condition acquisition unit 11 (# 01). For example, “Manufacturer =“ xyz ””, “Year = 2000-2005”, and the like are input as extraction conditions. Further, “manufactured number = 100”, “number of input = 300”, “manufacturing cost = 100,000 yen”, and the like are input as determination conditions. The extraction conditions acquired by the condition acquisition unit 11 are sent to the information acquisition unit 12, and the determination conditions are sent to the reusable machine determination unit 13.

  The information acquisition unit 12 that has acquired the extraction condition acquires information on the vending machine that satisfies the extraction condition from the disposal vending machine database D1 (# 02). For example, if the extraction conditions are “manufacturer =“ xyz ””, “year = 2000-2005”, “model number =“ abc ””, the manufacturer is “xyz” and the year is 2000 to 2005, In addition, information on the vending machine having the model number “abc” (hereinafter referred to as vending machine information) is acquired. As described above, in the present embodiment, since the information of FIG. 4 is recorded in the disposal vending machine database D1, the vending machine information of the present embodiment includes [machine number, model number, manufacturer, year, It can be expressed in the form of a list whose elements are [Check Date, Maintenance Base, Pre-Check Result]. Here, the pre-check results are [main body reuse availability, door reuse availability, design unit (table) reuse suitability, ..., heat insulation unit (bottom) reuse suitability].

  When the information acquisition unit 12 acquires the vending machine information, the information on the component unit of each casing unit of each vending machine included in the vending machine information (hereinafter referred to as component unit information) is acquired from the component unit database D2. (Referred to as # 03).

  FIG. 5 is a database schema of the component unit database D2 in the present embodiment. As shown in the figure, the component unit database D2 of the present embodiment includes a housing unit table, a component unit table, and a cost table. The housing unit table records the model number of the housing unit (main body, door) provided in each type of vending machine. The component unit table records the model numbers of the component units provided in the housing units of each model number. In the present embodiment, since the main body does not include a component unit, a component unit table linked to the main body model number is not shown. The cost table records the cost related to the part unit of each model number. In this embodiment, the cost required to take out the part unit from the vending machine to be discarded, the maintenance cost of the taken out part unit, the new part The price of the parts unit is recorded in the cost table. As described above, in this embodiment, there are five levels of suitability for reuse of component units, and maintenance is required in the case of ranks B to D. Therefore, maintenance costs are recorded for each rank.

  FIG. 6 is a flowchart showing a specific processing flow for the information acquisition unit 12 to acquire the component unit information from the component unit database D2. First, one element is selected from the vending machine information (# 11), and a model number (vending machine model number) is extracted from this element (# 12). Next, the information acquisition unit 12 uses the model number of the casing unit constituting the vending machine having the extracted model number, the component unit model number included in the casing unit, and the component unit for the component unit database D2. Create a query to obtain the cost for doing (# 13). Then, by causing the component unit database D2 to execute this query, the information acquisition unit 12 acquires component unit information (# 14). Accordingly, the component unit information includes the vending machine model number, the housing unit model number, the component unit model number, and the cost for using the component unit. This process is repeated until there is no unprocessed element in the vending machine information (No branch of # 15).

  Moreover, the information acquisition part 12 acquires the expense for transferring a vending machine from the transfer cost database D3 as transfer cost information (# 04). The transfer cost information includes, for example, the transfer cost from each maintenance base B to the reuse center A. More specifically, for example, the number of vending machines that can be loaded on one truck and the cost of transferring the vending machines from each maintenance base B to the reuse center A by the truck can be included.

  The vending machine information, the part unit information, and the transfer cost information acquired in this way are sent to the reusable machine determination unit 13.

  The reusable machine determination unit 13 that has acquired the determination conditions, vending machine information, parts unit information, and transfer cost information, acquires vending units and reusable parts units based on these conditions and information. A machine (hereinafter referred to as a reusable machine) is determined (# 05). Specifically, the reusable machine determination unit 13 acquires a housing unit or a part unit from the reusable machine so that the total cost for manufacturing a new vending machine is minimized under a predetermined condition. Determine the reusable machine. This predetermined condition is determined by the determination condition.

  As described above, the vending machine of this embodiment includes a main body and a door as a housing unit. Therefore, in order to obtain a housing unit from a discarded vending machine and combine the obtained housing unit to manufacture a new vending machine, at least a reusable main body and a reusable door are required. is necessary. Therefore, the reusable machine determination unit 13 creates a combination of a vending machine whose main body is reusable and a vending machine whose door is reusable from the vending machine information.

  However, simply creating a combination of a vending machine whose main body can be reused and a vending machine whose door can be reused may increase the cost. Therefore, in the vending machine reuse system of the present invention, the reusable machine is determined so that the total cost for manufacturing is minimized under predetermined conditions.

  For example, it is assumed that the maintenance base B1 has a vending machine V1 having a reusable door and a vending machine V2 having a reusable main body, and the maintenance base B2 has a vending machine V3 having a reusable main body. . It is assumed that the suitability for reuse of all the component units of these casing units is A (that is, the component units do not need to be serviced or replaced). In this case, in order to newly manufacture one vending machine, a combination of V1 and V2 and a combination of V1 and V3 are conceivable. When paying attention to the transfer cost, the transfer cost from the maintenance base B1 is required in the combination of V1 and V2. On the other hand, the combination of V1 and V3 requires a transfer cost from the maintenance site B1 and a transfer cost from the maintenance site B2. Therefore, the combination of V1 and V2 has the lowest cost. Accordingly, the reusable machines are V1 and V2, and a new vending machine is manufactured from the door acquired from V1 and the main body acquired from V2.

  Manufacturing costs can also be considered from other perspectives. For example, the cost of maintenance and replacement of the component unit. For example, it is assumed that vending machines similar to the above-described example are present at the maintenance bases B1 and B2. However, here, the suitability for reuse of the service unit V1 is C, the suitability for reuse of the service unit V2 is B, and the suitability of reuse of the service unit V3 is A.

  When a vending machine is manufactured from a reused casing unit, it is desirable that the suitability for reuse of all component units, that is, the quality is A. Therefore, in the above example, if the door is acquired from V1, the main body is acquired from V2, and the customer service unit is acquired from V3, the quality of all the component units is A. On the other hand, the customer service unit acquired from V1 or V2 can be maintained and used. Therefore, these costs are compared. That is, the cost of removing, servicing, and attaching the customer service unit from V1 and V2 is compared with the cost of transferring V3 from the maintenance base B2, removing the customer service unit, and installing it in a new vending machine, so the total cost is small The combination is selected. For example, if the cost for reusing the customer service unit acquired from V2 <the cost for reusing the service unit acquired from V1 <the cost for reusing the service unit acquired from V3, the cost is minimal. What becomes is a combination of V1 and V2. Accordingly, the reusable machines are V1 and V2, and a new vending machine is manufactured from the door acquired from V1, the main body acquired from V2, and the customer service unit acquired from V2.

  However, if the manufacturing cost of the vending machine including the cost for reusing the customer service unit acquired from V2 exceeds the manufacturing cost included in the determination conditions, it is decided not to replace the service unit of V1. It doesn't matter. In this case, the reusable machines are V1 and V2, and a new vending machine is manufactured from the door acquired from V1 and the main body acquired from V2, and the suitability for reuse of the customer service unit of this vending machine, That is, the quality remains C.

  When the quality of the component unit is set to A, a new component unit may be used instead of reusing the component unit acquired from the discarded vending machine. Of course, which of these is used is determined based on the cost. That is, the transfer cost of the vending machine for acquiring the component unit + the removal cost of the component unit + the maintenance cost of the component unit and the price of the new component unit are compared to determine which one to use.

  In the above-described example, since one vending machine was manufactured, a reusable machine could be determined by relatively simple cost comparison. However, in reality, the vending machine reuse system of the present invention is used for manufacturing a plurality of vending machines, and the number of vending machines integrated in the maintenance base B or there is also increased. . For this reason, it is difficult to determine the reusable machine by the simple cost comparison as described above, but the reusable machine can be determined by using a technique such as brute force calculation or linear programming.

  In the present embodiment, the reusable machine is not determined so that the total cost for manufacturing the predetermined number of vending machines is minimized, but the total cost is determined under a predetermined condition, that is, the determined condition. The reusable machine is determined so as to minimize it. For example, by setting the number of input units in the determination condition, the reusable unit is determined so as to minimize the total cost while keeping the number of vending machines used for reuse within the set number of input units. The predetermined condition in the present invention includes no condition. That is, this is a case where the determination condition is not set, and in this case, the reusable machine is determined so as to minimize the total cost.

  Thus, the information on the reusable machine determined (hereinafter referred to as reusable machine information) is sent to the transfer instruction unit 14. The reusable machine determination unit 13 creates and outputs an instruction for manufacturing a new vending machine based on the reusable machine information. In this instruction sheet, from which vending machine each housing unit is obtained, combination of each housing unit, each vending unit is obtained from which vending machine, whether maintenance is necessary, Or, whether a new part unit is used is described.

  The transfer instructing unit 14 sends a vending machine transfer instruction to each maintenance base B based on the reuse machine information (# 06). When the vending machine is transferred from each maintenance base B to the reuse center A, a new vending machine is manufactured based on the instruction sheet.

[Another embodiment]
(1) In the above-described embodiment, the transfer instruction unit 14 is configured to request the vending machine to be transferred. However, the transfer request may be made artificially based on the output of the reusable machine determination unit 13. I do not care.

(2) In the above-described embodiment, the reusable machine determination unit 13 determines the reusable machine including the transfer cost of the vending machine to be discarded, but even if the reusable machine is determined without including the transfer cost. I do not care. In this case, the transfer cost database D3 becomes unnecessary.

  The present invention can be used in a vending machine reuse system for manufacturing a new vending machine from a casing unit acquired from a vending machine to be discarded.
