Description

  The present invention provides a combination weigher that uses RFID technology to determine whether a component is a genuine product.

  When filling an object to be weighed into a container or the like as a product or the like, it is required to accurately and automatically put the object to be weighed into the container or the like at high speed. A combination weigher is used as a means for that purpose. The combination weigher variously combines the measured values of the objects to be weighed in a plurality of weighing containers, and among these combinations, the total weight is the most suitable for the target weight. A combination of close values is selected, and the object to be weighed is discharged from the weighing container of the selected combination.

  In combination weighers, many components having movable parts such as hoppers having an opening / closing part at the outlet and feeders having a vibrating part are often used. Since a combination weigher performs a large number of weighings at high speed, the components having these movable parts are easily consumed, and are sold individually as consumable spare parts. However, unauthorized second-source products (non-genuine products) that are not contracted with the original product manufacturer may be on the market, and as a result of the use of such non-genuine products, measurement errors or damage in combination weighers Etc. have occurred.

  In this regard, Patent Document 1 proposes a genuine device discrimination system including a host device and an element device having a wireless tag for the purpose of preventing use of an illegally imitated element device. The host device includes a command generation module that generates a command to be transmitted to the outside, and a reader / writer that includes an information determination module that determines various types of information transmitted from the outside. On the other hand, the wireless tag included in the element device includes a memory that stores various information as a genuine element device that conforms to the genuine standard of the host device, a recognition signal determination module that determines whether or not the command is a regular command, And an information reading module for reading information stored in the memory and transmitting it to the reader / writer when it is determined that the command is a regular command.

A combination weigher that performs maintenance of components using a wireless tag is disclosed in Patent Document 2. This combination weigher is configured to record maintenance management information in a component using RFID (Radio Frequency IDentification) technology, and includes a component having a movable part or a part in contact with an object to be measured, An RF tag that is attached and records information for recording maintenance management information including at least one of identification information of the component, cumulative driving time, cumulative load weight, cumulative cleaning frequency, and final cleaning time; An RF tag reader / writer that reads and writes maintenance management information recorded on the RF tag.

  Unlike the copying machine exemplified in Patent Document 1, the combination weigher has many consumable parts of the same type such as an opening / closing part of a hopper and a vibrating part of a feeder. Therefore, it is a labor-intensive work to search for consumables one by one and to find a non-genuine one among many consumables. In addition, the structure of the combination weigher is complicated, and there are many consumables that cannot be visually confirmed whether they are non-genuine products unless they are disassembled.

An RF tag reader / writer that reads and writes information held by the RF tag, and the operation setting display cannot read the individual identification information of the component held by the RF tag using the RF tag reader / writer. Sometimes, the component is determined as a non-genuine product, and the result of the determination is displayed on the display unit.

  According to the combination weigher having the above-described configuration, it is possible to reliably determine whether or not the component of the combination weigher is a genuine product without disassembling the component by using RFID technology. Then, by removing the components that are identified as non-genuine products from the combination weigher, such as measurement errors and damages to the components that occur when performing the weighing operation with the non-genuine product components installed in the combination weigher. Problems can be prevented or eliminated.

  In the present embodiment, the arithmetic controller 16 means not only a single arithmetic controller but also an arithmetic controller group including a plurality of arithmetic controllers. Therefore, the arithmetic controller 16 may be composed of a single arithmetic controller, or may be composed of a plurality of arithmetic controllers that are arranged in a distributed manner and controlled in cooperation.

[Operation of combination scale 99]
The operation of the combination scale 99 configured as described above will be described. The operation controller 16 of the combination weigher 99 executes the operation program stored in the storage unit 22 to control the operation of the combination weigher 99 and perform the combination operation. Parameters such as combination target weight values and operating speed conditions are input in advance from the operation setting display 17 to the arithmetic control unit 21 of the arithmetic control unit 16 and stored in the storage unit 22. The data is read from the storage unit 22 as necessary.

  When starting the weighing operation, the arithmetic controller 16 first controls the vibrator 4 of the distributed feeder 30 and the vibrator 6 of the linear feeder 50 via the vibration control circuit 27 so as to operate. Thus, the objects to be weighed supplied from the supply device 1 onto the dispersion feeder 30 are distributed in the circumferential direction from the dispersion feeder 30 and fed to the supply hoppers 7 through the linearly-advanced feeders 50 arranged radially. The At this time, the arithmetic controller 16 detects the layer thickness of the object to be weighed on the dispersion feeder 30 by the level detector 2, and when the amount of the object to be weighed becomes smaller than a predetermined amount, the operation device 16 is operated. A predetermined amount or more of an object to be weighed is always supplied onto the dispersion feeder 30.

  Subsequently, the arithmetic controller 16 detects that the weighing hopper 8 is empty, and controls the gate 7 a of the supply hopper 7 to be opened via the gate drive circuit 26. As a result, the object to be weighed is fed from the supply hopper 7 to the weighing hopper 8. When an object to be weighed is put into the weighing hopper 8, the arithmetic controller 16 sends the measurement value (weight of the object to be weighed held in each weighing hopper 8) by the weight sensor 9 via the A / D conversion circuit 25. The combination calculation is performed based on the detected weight of the object to be weighed. In this combination calculation, a combination in which the sum of the weight values of the objects weighed by the weight sensor 9 from the plurality of weighing hoppers 8 is within a predetermined weight range (allowable weight range with respect to the target weight). Is determined, and the combination of the weighing hoppers 8 to be discharged is selected.

  Then, the calculation controller 16 opens the gate 8a of the weighing hopper 8 selected for the combination obtained by the combination calculation via the gate drive circuit 26, and discharges the objects to be weighed onto the collective chute 11. The objects to be weighed are collected on the collecting chute 11 by the sliding funnel 12 and accommodated in the collecting hopper 13. When a discharge permission signal is input from the packaging machine, the arithmetic controller 16 opens the gate 13a of the collecting hopper 13 and discharges a predetermined amount of objects held by the collecting hopper 13 to the packaging machine. Outputs a discharge completion signal to the packaging machine. In the packaging machine, an operation such as a sealing operation is performed based on the input timing of the discharge completion signal from the combination scale 99. Thereafter, by repeating the same operation as described above, an amount of an object to be weighed that satisfies a certain condition is discharged to the packaging machine.

[Genuine product discrimination mechanism]
Next, the genuine product discrimination mechanism of the components of the combination weigher using the RFID technology will be described below. The genuine product discriminating mechanism of the components of the combination weigher is for discriminating whether or not the components (particularly consumables) included in the combination weigher 99 are genuine products.

  FIG. 5 is a block diagram showing the configuration of the genuine product discriminating mechanism according to the first embodiment. As shown in FIGS. 3 and 5, the genuine product discrimination mechanism provided in the combination weigher 99 is attached to each of the consumables of the vibrator 6, the supply hopper 7, the weight sensor 9, and the weighing hopper 8 of the linear feeder 50.

The components are not limited to these.

  Here, the RF tags 53, 54, 55, and 56 will be described. Since the RF tags 53, 54, 55, and 56 all have the same configuration, the configuration of the RF tag 53 will be described in detail here.

  FIG. 6 is a block diagram showing a schematic configuration of the RF tag. As shown in FIG. 6, the RF tag 53 includes an antenna coil 32, a resonant capacitor 33, a CPU 34, a rectifying unit 35, a modem unit 36, a memory unit 37, and a smoothing unit 38.

  Next, the operation of the RF tag 53 configured as described above will be described. The resonance capacitor 33 included in the RF tag 53 is connected in parallel with the antenna coil 32 and operates as a resonance circuit 39. When a predetermined high-frequency power radio signal (carrier wave) is transmitted from the outside to the resonance circuit 39, the resonance circuit 39 receives the signal by the antenna coil 32 and inputs the received carrier wave to the rectifying unit 35. The rectifier 35, together with the smoother 38, rectifies and smoothes the carrier wave to generate DC power (power supply power) having a constant voltage. The generated power supply power is supplied to a given site in the RF tag 53.

  In the radio wave signal sent from the RF tag reader / writer 52 to the RF tag 53, the signal is superimposed on the carrier wave. The radio signal is demodulated by the modem 36 and separated, and the signal is input to the CPU 34. The CPU 34 executes processing according to the signal input from the modem unit 36 in accordance with the operation program stored in the memory unit 37. That is, the CPU 34 writes the received value in the memory unit 37 as necessary, or reads data from the memory unit 37 as necessary and sends it to the modem unit 36. The modem unit 36 modulates the carrier wave using the received data. By this modulation, the data is superimposed on the carrier wave and transmitted from the antenna coil 32 to the RF tag reader / writer 52 from the RF tag 53 as a radio wave signal.

The arithmetic control unit 171 is configured to be capable of bidirectional communication with the arithmetic controller 16 via the first input / output circuit 175. Note that the communication method between the arithmetic controller 16 and the operation setting indicator 17 may be wired or wireless, but the former can transmit and receive more information in a shorter time. preferable. Information input by the operator operating the input unit 173 of the operation setting indicator 17 is input from the arithmetic control unit 171 to the arithmetic controller 16, and from the arithmetic controller 16 to the arithmetic control unit 171. The information output to is displayed on the display unit 174.

  The storage unit 172 of the operation setting display 17 is provided with a component management database and a component manufacturing database.

  In the component management database, management information (for example, individual identification ID number, component name, model number) related to each component provided in the combination scale 99 is stored, and it corresponds based on the individual identification ID number. It is constructed so that the management information of the component can be read out. Here, the “individual identification ID number” is individual identification information for identifying a component. The individual identification ID number may be a product ID number assigned to the RF tag itself, or may be a number registered separately. Further, the individual identification ID number is not limited to a number consisting of numbers, and may be a character string consisting of any one of alphabets, symbols and numbers, or a combination thereof. However, the individual identification ID number is a number unique to each component.

  In the component manufacturing database, manufacturing information (for example, an individual identification ID number, a component name, a model number, a manufacturing date, (Manufacturing number, manufacturer, etc.) are stored, and the manufacturing information of the corresponding component can be read based on the individual identification ID number. The component manufacturing database is preferably stored in a storage medium that can be attached to and detached from the operation setting display 17, and an operator who performs maintenance of the combination weigher 99 includes the latest component manufacturing information. It is preferable to mount the element manufacturing database on the operation setting display 17 to inspect the constituent elements.

As shown in FIG. 7, the RF tag reader / writer 52 includes a CPU 40, a memory unit 41, a transmission unit 42, a transmission antenna 43, a reception unit 44, and a reception antenna 45. The CPU 40 provided in the RF tag reader / writer 52 can exchange signals with the arithmetic control unit 171 in both directions.

  Next, a data write operation to the RF tags 53 to 56 of the RF tag reader / writer 52 will be described. First, the CPU 40 receives from the arithmetic control unit 171 the ID numbers of the RF tags 53 to 20 to which data is to be written, the contents of the data to be written (hereinafter, write data), and the like. The received write data is stored in the memory unit 41. Next, the CPU 40 transmits only the carrier wave from the transmission unit 42 and transmits it as a power radio signal from the transmission antenna 43. Further, the ID number is read from the memory unit 41, and this is also superimposed on the carrier wave by the transmission unit 42 and transmitted from the transmission antenna 43 to start communication with the specific RF tags 53 to 56. Furthermore, the CPU 40 reads data to be written from the memory unit 41, superimposes it on a carrier wave by the transmission unit 42 through modulation, and transmits it from the transmission antenna 43.

First, the CPU 40 receives the ID numbers and the like of the RF tags 53 to 56 from which data is to be read from the arithmetic control unit 171. The received data and the like are stored in the memory unit 41. Next, the CPU 40 transmits only the carrier wave from the transmission unit 42 and transmits it as a power radio signal from the transmission antenna 43. Further, the ID number is read from the memory unit 41, and the transmitter unit 42 also superimposes it on the power radio signal by modulation and transmits it from the transmission antenna 43, thereby starting communication with specific RF tags 53 to 56. .

The arithmetic control unit 171 of the operation setting display 17 executes a predetermined program to control the operation of the operation setting display 17 and thereby determines whether the component to be inspected in the operation setting display 17 is a genuine product. Operation is performed.

  As shown in FIG. 8, first, the operator brings the operation setting display 17 close to the component to be inspected, and reads the information held by the RF tag attached to the component to the RF tag reader / writer 52. An operation is performed to execute it (step S61). Note that the component to which the RF tag is not attached is a non-genuine product without being identified using the RF tag reader / writer 52, and the component to which the RF tag is attached will be described below. Thus, it is possible to determine whether the product is a genuine product or a non-genuine product by identifying the constituent elements based on the individual identification ID number.

  The RF tag reader / writer 52 that has read the information held by the RF tag transmits this information to the arithmetic control unit 171. The information read from the RF tag 54 includes the individual identification ID number of the component, and the calculation control unit 171 displays this individual identification ID number on the display unit 174 (step S63). Here, when the information stored in the RF tag cannot be read out, or when the read information does not include the individual identification ID number (for example, when it is a fake RF tag or RF out of product specifications) When an RF tag reading error occurs (such as a tag) (NO in step S62), the arithmetic control unit 171 determines that the inspected component is a non-genuine product (step S71).

  Subsequently, the arithmetic control unit 171 reads the management information of the component corresponding to the read individual identification information with reference to the component management database (step S64). If there is management information of the constituent element corresponding to the individual identification information read in the constituent element management database (YES in step S65), the arithmetic control unit 171 determines that the inspected constituent element is a genuine product (step S71). .

  On the other hand, when there is no management information of the corresponding component in the component management database (NO in step S65), the arithmetic control unit 171 refers to the component manufacturing database and configures the configuration corresponding to the read individual identification information. The manufacturing information of the element is read (step S68), management information of the constituent element corresponding to the individual identification information read based on the manufacturing information is newly created and stored in the constituent element management database (step S70) and inspected. The component is discriminated as a genuine product (step S71). If the manufacturing information of the component corresponding to the read individual identification information does not exist in the component manufacturing database (NO in step S69), the arithmetic control unit 171 determines that the inspected component is a non-genuine product ( Step S71). Finally, the arithmetic control unit 171 causes the display unit 174 to display the determination result.

  At this time, if the inspected component is a non-genuine product, a warning may be displayed together with the determination result. Moreover, it can also be configured so that the weighing operation of the combination weigher 99 cannot be started when the inspected component is determined to be a non-genuine product. For example, the weighing operation of the combination weigher 99 can be performed by temporarily disabling input of an operation command to the main body of the combination weigher by the ON-OFF switch of the weighing operation of the combination weigher 99 provided on the operation setting display 17. Can be configured not to start. In this way, when the components of the non-genuine product are incorporated in the combination balance 99, the measurement operation of the combination weigher 99 cannot be forcibly started, thereby using the components of the non-genuine product. It is possible to prevent the occurrence of defects.

  If the inspected component is a genuine product, the management information of the component may be displayed on the display unit 174 of the operation setting display 17 together with the determination result. In this case, it may be configured such that an operator who has confirmed the management information of the component displayed on the display unit 174 of the operation setting display 17 can place an order for the component by operating the arithmetic control unit 171. FIG. 9 is a block diagram showing a configuration of another aspect of the genuine product discrimination mechanism. For example, as shown in FIG. 9, the operation setting indicator 17 is configured to be connectable to a communication network 60 such as the Internet via the second input / output circuit 176, and the operation setting indicator 17 includes the management information of the constituent elements. Order data including an order request is created and transmitted to an order receiving server 65, which is a network server operated by a manufacturer that manufactures consumable spare parts, via a communication network, thereby placing an order for components. can do. Thereby, it is possible to reliably place an order for the component to be ordered. The order data transmitted to the order server 65 is stored in an order database constructed in the order server 65, and this order data is confirmed and ordered by the person in charge of the manufacturer who manufactures the consumable spare parts. Arrangements are made to deliver (consumable spare parts) to the delivery destination. The second input / output circuit 176 can be constituted by a modem such as a modem.

  As described above, in the combination weigher 99 according to the present embodiment, it is possible to determine whether or not the components included in the combination weigher 99 are genuine products using RFID technology. As a result, it is possible to prevent the occurrence of troubles due to the use of non-genuine components (for example, poor measurement due to the use of hoppers with poor movement). Further, the information held by the RF tag attached to the component to be inspected can be read by appropriately moving the operation setting indicator 17 without disassembling the combination balance 99 or its constituent elements. Can be performed easily and quickly. In particular, since the combination balance 99 has a large number of components, it is useful to be able to easily and quickly inspect individual components.

  Further, in the combination weigher 99 according to the present embodiment, when the genuine component is not registered in the component management database (for example, when it is newly attached to the combination weigher 99), the component is genuine. A new component can be registered in the component management database during the process of determining whether the product is a product. As a result, a new component can be registered in the component management database, and can be prepared for the inspection to determine the genuine product of the component from the next time.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. In the combination weigher 99 according to the first embodiment, the component management database and the component manufacturing database are provided in the storage unit 172 of the operation setting display 17. In this embodiment, these databases are managed later. It is managed centrally on the server so that it can be easily maintained and updated.

[Genuine product discrimination system for components of combination weighers]
A genuine product discriminating system for components of a combination weigher using RFID technology will be described below. The genuine product discrimination system for the components of the combination weigher is for discriminating whether or not the components (particularly consumables) included in the combination weigher 99 are genuine products. The configuration of the main body of the combination weigher 99 according to the second embodiment (the portion excluding the operation setting indicator 17 of the combination weigher 99) is the same as that described in the first embodiment. The duplicate description about is omitted.

  FIG. 10 is a block diagram showing a configuration of a genuine product discrimination system according to the second embodiment. As shown in FIG. 10, the operation setting indicator 17 of the combination weigher 99, the management server 61 operated by the company that manages the combination weigher and its components, and the consumable spare parts (components) are manufactured. A communication network 60 is communicably connected to an order receiving server 65 operated by a manufacturer. The combination weigher 99, the management server 61, and the order receiving server 65 constitute a genuine product discrimination system for the components of the combination weigher.

  First, a mechanism for discriminating genuine products included in the combination weigher 99 will be described.

  The genuine product discriminating mechanism provided in the combination weigher 99 includes RF tags 53, 54, 55, and 56 attached to the consumables of the vibrator 6, the supply hopper 7, the weight sensor 9, and the weighing hopper 8 of the linear feeder 50. And an operation setting display 17 equipped with an RF tag reader / writer 52. The configuration of the RF tags 53, 54, 55, and 56 is the same as that described in the first embodiment, and a description thereof will be omitted.

  The operation setting display 17 will be described. The operation setting display 17 includes an arithmetic control unit 171, a storage unit 172 connected to the arithmetic control unit 171, an input unit 173, a display unit 174, a first input / output circuit 175, a second output / input circuit 176, and an RF. A tag reader / writer 52 is provided. The configuration of the RF tag reader / writer 52 is the same as that described in the first embodiment, and a description thereof will be omitted.

  The arithmetic control unit 171 is configured to be capable of bidirectional communication with the arithmetic controller 16 via the first input / output circuit 175. Note that the communication method between the arithmetic controller 16 and the operation setting indicator 17 may be wired or wireless, but the former can transmit and receive more information in a shorter time. preferable. Information input by the operator operating the input unit 173 of the operation setting indicator 17 is input from the arithmetic control unit 171 to the arithmetic controller 16, and from the arithmetic controller 16 to the arithmetic control unit 171. The information output to is displayed on the display unit 174.

  The operation setting indicator 17 is connected to a wide-area communication network 60 such as the Internet via a second input / output circuit 176. The communication network 60 is also connected with a management server 61 owned by the management company and an order receiving server 65 of a manufacturer of consumable spare parts. That is, the operation setting display 17, the management server 61, and the order receiving server 65 can exchange information with each other via the communication network 60.

  Next, the management server 61 will be described.

  The management server 61 is a network server operated by a company that manages the combination weigher and its constituent elements, and is an ASP server that operates an application program in the system and provides a service. The management server 61 includes a management program, a component management database, a component manufacturing database, and a combination scale management database. Information stored in the database of the management server 61 is managed secretly. The management server 61 receives a request to read out information stored in the database by operating the management program, and receives a request for a corresponding component from the function of transmitting the corresponding information to the request source or an order request. The server 65 has a function of placing an order.

  In the component element management database, management information (for example, individual identification ID number, component element name, model number, attached substrate identification ID number, etc.) relating to each component element is stored, and based on the individual identification ID number It is constructed so that the management information of the corresponding component can be read out. Here, the “substrate identification ID number” is substrate identification information for identifying the substrate of the combination scale 99. The substrate identification ID number is not limited to a number consisting of numbers, and may be a character string consisting of any one of alphabets, symbols and numbers, or a combination thereof. However, the base identification ID number is a number unique to each combination balance 99.

  In the component manufacturing database, manufacturing information (for example, individual identification ID number, component name, model number, year of manufacture) of each component (consumable spare part) that is normally manufactured by a manufacturer that manufactures consumable spare parts (Month / Date, Manufacturing Number, Manufacturer, etc.) are stored, and the manufacturing information of the corresponding component can be read based on the individual identification ID number.

  The combination weigher management database stores management information (for example, substrate identification ID number, product name, model number, date of manufacture, delivery destination, component, etc.) of the combination weigher. Based on the substrate identification ID number It is constructed so that the management information of the corresponding combination weigher can be read out.

  Next, the order receiving server 65 will be described.

  The order receiving server 65 is a network server operated by a manufacturer that manufactures consumable spare parts, and is an ASP server that operates an application program in the system and provides a service. The order receiving server 65 includes an order receiving program and an order receiving database. Order data is stored in the order database.

[Operation of genuine product discrimination system of combination weigher when discriminating genuine product]
Here, the operation of the genuine product discrimination system of the components of the combination weigher will be described focusing on the operation of the operation setting display 17. Hereinafter, a procedure for determining whether or not one replaceable component constituting the main body of the combination weigher 99 is a genuine product will be described. In the same procedure, the vibrator 6 of the linear feeder 50, It is possible to determine whether or not the components of the combination weigher 99 such as the supply hopper 7, the weighing hopper 8, or the weight sensor 9 are genuine products.

  An RF tag holding information including an individual identification ID number is attached to the component in advance. Further, the base identification ID number of the combination scale 99 is stored in the storage unit 172 of the operation setting display 17.

  FIG. 11 is a flowchart showing the flow of the genuine product discrimination operation of the constituent elements. The arithmetic control unit 171 of the operation setting display 17 executes a predetermined program to control the operation of the operation setting display 17 and thereby determines whether the component to be inspected in the operation setting display 17 is a genuine product. Operation is performed.

  As shown in FIG. 11, first, the operator brings the operation setting display 17 close to the component to be inspected, and reads the information held by the RF tag attached to the component to the RF tag reader / writer 52. An operation is performed for execution (step S01). The constituent elements of the combination weigher 99 including the supply hopper 7 are often made of metal such as stainless steel, and normal reading may not be possible due to reflection, diffusion or attenuation of radio waves. It is preferable to perform the reading operation with the RF tag close to the component RF tag.

  Note that the component to which the RF tag is not attached is a non-genuine product without being identified using the RF tag reader / writer 52, and the component to which the RF tag is attached will be described below. Thus, it is possible to determine whether the product is a genuine product or a non-genuine product by identifying the constituent elements based on the individual identification ID number.

  The RF tag reader / writer 52 that has read the information held by the RF tag transmits this information to the arithmetic control unit 171. The information read from the RF tag 54 includes the individual identification ID number of the component, and the arithmetic control unit 171 displays the individual identification ID number on the display unit 174 (step S03) and the communication network. A management information transmission request is transmitted together with the individual identification ID number to the management server 61 via 60 (step S04). Here, when the information stored in the RF tag cannot be read out, or when the read information does not include the individual identification ID number (for example, when it is a fake RF tag or RF out of product specifications) When an RF tag reading error occurs (in the case of a tag) (NO in step S02), the arithmetic control unit 171 determines that the inspected component is a non-genuine product (step S15).

  The management server 61 that has received the management information transmission request together with the individual identification ID number (YES in step S05) reads out the management information of the constituent element corresponding to the individual identification ID number from the constituent element management database (step S06), and returns it. Data is created (step S07), and the reply data is transmitted via the communication network 60 to the operation setting display 17 that has transmitted the management information transmission request (step S08).

  Here, when creating the reply data, the management server 61, when there is management information of the component corresponding to the received individual identification ID number, consists of the management information of the component including at least the substrate identification ID number. While the reply data is created, if there is no management information of the component corresponding to the received individual identification ID number, reply data including an error message is created. This error message conveys that there is no component corresponding to the individual identification ID number.

  The calculation control unit 171 of the operation setting display 17 that has received the reply data (YES in step S09), if the reply data is an error message (YES in step S09), the inspected component is a non-genuine product. Is determined. On the other hand, if the reply data is not an error message (NO in step S09), the reply data sent from the management server 61 to the operation setting display 17 includes at least a base identification ID number. Therefore, the arithmetic control unit 171 reads out the substrate identification ID number held by itself from the storage unit 172 (step S11), and compares the received substrate identification ID number with the substrate identification ID number held by itself (step S12). . If the two match (YES in step S12), the arithmetic control unit 171 of the operation setting display 17 determines that the inspected component is a genuine product (step S13), and if both do not match (NO in step S12). ), The inspected component is determined as a non-genuine product (step S15). Here, if the received substrate identification ID number is different from the substrate identification ID number held by itself, it is estimated that the individual identification ID number is improperly assigned to the RF tag attached to the component, and the checked configuration The element is identified as non-genuine.

  Finally, the calculation control unit 171 of the operation setting display 17 displays the determination result on the display unit 174. If the inspected component is a genuine product, the display unit 174 displays that the component is a genuine product. On the other hand, if the inspected component is a non-genuine product, a warning is displayed on the display unit 174 together with the fact that it is a non-genuine product. In this way, by visually recognizing the discrimination result displayed on the arithmetic control unit 171 of the operation setting display 17, the operator can surely know whether the inspected component is a genuine product or a non-genuine product. it can.

  As described above, it is possible to determine whether or not the components included in the combination weigher 99 are genuine products using the RFID technology. As a result, it is possible to prevent the occurrence of troubles due to the use of non-genuine components (for example, poor measurement due to the use of hoppers with poor movement). Further, the information held by the RF tag attached to the component to be inspected can be read by appropriately moving the operation setting indicator 17 without disassembling the combination balance 99 or its constituent elements. Can be performed easily and quickly. In particular, since the combination balance 99 has a large number of components, it is useful to be able to easily and quickly inspect individual components.

  Note that, as described above, when the inspected component is determined to be a non-genuine product, the weighing operation of the combination weigher 99 may not be started. For example, the weighing operation of the combination weigher 99 can be performed by temporarily disabling input of an operation command to the main body of the combination weigher by the ON-OFF switch of the weighing operation of the combination weigher 99 provided on the operation setting display 17. Can be configured not to start. In this way, when the components of the non-genuine product are incorporated in the combination balance 99, the measurement operation of the combination weigher 99 cannot be forcibly started, thereby using the components of the non-genuine product. It is possible to prevent the occurrence of defects.

  Further, the component (consumable spare part) can be ordered using the individual identification ID number read from the RF tag attached to the component as described above. Hereinafter, the operation of the operation setting display 17 when ordering consumable spare parts will be described.

  FIG. 12 is a flowchart showing the flow of a component ordering operation. As shown in FIG. 12, first, the operator brings the operation setting indicator 17 close to the component for which the consumable spare part is to be ordered, and the RF tag reader / writer 52 holds the information held by the RF tag attached to the component. An operation is performed to execute the reading operation (step S21). The RF tag reader / writer 52 that has read the information held by the RF tag transmits this information to the arithmetic control unit 171. The information held by the RF tag includes the individual identification ID number of the component, and the calculation control unit 171 displays the individual identification ID number on the display unit 174 (step S22) and also sets the communication network 60. An ordering request is transmitted to the management server 61 together with the individual identification ID number (step S23).

  The management server 61 that has received the order request together with the individual identification ID number (YES in step S24) reads the management information of the component corresponding to the individual identification ID number from the component management database (step S25). This component management information includes the part name, model number, and attached base identification ID number. Further, the management server 61 reads management information of the combination weigher corresponding to the read substrate identification ID number from the combination weigh management database (step S26). The management information of the combination weigher includes the product name of the combination weigher, the product model number, and the delivery destination. Then, the management server 61 creates ordering data from the read management information of the constituent elements and the management information of the combination weigher (step S27). This ordering data includes the component name, model number, base identification ID number to be attached, product name of the combination weigher, product model number, delivery destination, and the like. The management server 61 transmits this ordering data to the order receiving server 65 and the operation setting display 17 that has issued the ordering request via the communication network 60 (step S28).

  The calculation control unit 171 of the operation setting display 17 that has received the order data (YES in step S29) causes the display unit 174 to display an ordered message (step S30). On the other hand, the order receiving server 65 that has received the order data sequentially stores the order data in the order database. The order data stored in the order database can be read by the information terminal (not shown) of the manufacturer that produces the consumable spare parts. The person in charge of the manufacturer places an order based on the order data read by the information terminal. Arranges delivery of the components to the customer.

  In the above description, the order data is transmitted directly from the management server 61 to the order receiving server 65. However, the order setting data may be transmitted from the operation setting display 17 that has received the order data to the order receiving server 65. it can. In this case, the operation setting display 17 that has received the order data displays the received order data and the order switch on the display unit 174, receives the operation of the order switch by the operator who has confirmed the order data, and displays the operation setting display. The order data can be transmitted from the device 17 to the order receiving server 65 via the communication network 60. As described above, according to the configuration in which the order data is transmitted from the operation setting display 17 to the order receiving server 65, the operator confirms the contents of the order data on the operation setting display 17, so that the error is more accurate. You can place a reliable order without any.

  In the above description, the management server 61 and the order receiving server 65 are configured as separate bodies, but they can also be configured integrally. FIG. 14 is a block diagram showing a configuration of another aspect of the genuine product discrimination system. As shown in FIG. 14, the management server 61 can also be configured to have a function as the order receiving server 65. In this case, the step of transmitting the order data from the management server 61 to the order receiving server 65 is unnecessary, and the processing flow is simplified.

  When the component ordered as described above is delivered and newly attached to the combination balance 99, it is necessary to register this component in the component management database of the management server 61. Hereinafter, the operation at the time of new registration of the components of the operation setting display 17 will be described.

  FIG. 13 is a flowchart showing a flow of a new registration operation of a component. As shown in FIG. 13, first, the operator brings the operation setting indicator 17 close to the component to be newly registered, and reads the information held by the RF tag attached to the component to the RF tag reader / writer 52. An operation is performed to execute (Step S41). The RF tag reader / writer 52 that has read the information held by the RF tag transmits this information to the arithmetic control unit 171. The information held by the RF tag includes the individual identification ID number of the component, and the calculation control unit 171 displays the individual identification ID number on the display unit 174 (step S42), and the communication network 60 is displayed. The individual identification ID number, the substrate identification ID number, and the registration request are transmitted to the management server 61 (step S43).

  The management server 61 that has received the individual identification ID number, the base body identification ID number, and the registration request (YES in step S44) refers to the component management database and confirms that there is no corresponding individual identification ID number (step In S45, the manufacturing information of the component having the corresponding individual identification ID number is read with reference to the component manufacturing database (step S46). Here, when the received individual identification ID number has already been registered in the component management database (NO in step S45), the management server 61 includes the manufacturing information of the component with the corresponding individual identification ID number as the component. If it is not in the manufacturing database (NO in step S46), a registration failure message is created (step S50).

  Further, the management server 61 newly creates component management information from the read manufacturing information of the component and the received substrate identification ID number, and stores it in the component management database. That is, the management information of the component having the received individual identification ID number is newly registered in the component management database (step S48). After completing the registration, the management server 61 creates a registration completion message (step S49). Then, the management server 61 transmits a message (registration completion message or registration failure message) to the operation setting display 17 that has transmitted the registration request (step S51). The calculation control unit 171 of the operation setting display 17 that has received the message (YES in step S52) displays the received message on the display unit 174 (step S53).

  If a component is newly registered in the component management database of the management server 61 in the above flow, it can be determined whether or not the component is a genuine product in the registration process flow. Can avoid registration. In other words, if the message received at the end of the registration process is a registration failure message, the component to be registered is a consumable spare that has already been registered in an individual identification ID number and has been illegally manufactured. It is highly possible that the product is a consumable spare item that is a non-regularly manufactured consumable product that is not registered in the component manufacturing database. In such a case, even if there is a registration request, the component management database is not registered.

  In the combination weigher and the genuine product discriminating system for the components of the combination weigher according to the present invention, it is possible to use RFID technology to replace replaceable components of the combination weigher without disassembling the components and performing simple operations. Since it is possible to reliably determine whether or not the component is a genuine product, the components of the combination weigher are not limited to the illustrated linear feeder, supply hopper, weighing hopper, and weight sensor. The present invention can be widely applied to component parts.
