BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material replacement monitoring method and system, and more specifically, an incorrect replacement material when replenishing material in a production facility, or a replacement when replenishing a component in an electronic component mounting facility. The present invention relates to a monitoring method and a monitoring system for preventing mistakes in parts and manufacturing high quality products.

2. Description of the Related Art As is well known, in general production equipment and mounting equipment, there is no space to secure all the materials or parts collectively, so that the materials or parts are replenished each time they are used up. Is being done. In most cases, electronic components mounted on a printed circuit board or the like are supplied to mounting equipment in a form in which a predetermined number of band-shaped components are wound on a reel. Therefore, when the predetermined number of parts are used up in the mounting process, the reels are replaced to replenish the parts.

FIG. 8 is a schematic view showing a part relating to component supply of a conventional mounting facility for mounting electronic components on a printed circuit board or the like. Hereinafter, with reference to FIG. 8, a conventional component replacement method performed by mounting equipment will be described. When a component runs out in the mounting equipment, an empty reel (hereinafter referred to as an empty reel) loaded in the supply position 104 of the component on the component supply table 103 and a new reel filled with the component. Parts are replenished by exchanging (hereinafter, referred to as replenishment reel). Normally, the mounting equipment displays the supply position or the part number of the component to be replenished on the screen (not shown) and stops the operation when the component runs out. After confirming the supply position and the part number of the parts to be replenished on the screen, the worker replaces the empty reel with a supply reel having the same part number and restarts the operation of the mounting equipment.

However, since this reel replacement is artificially performed by a worker, in a mounting facility using a plurality of parts, a supply reel having an incorrect part number is replaced, or a supply reel is replaced at an incorrect supply position. There is a risk of being killed. Therefore, conventionally, in mounting equipment that uses a plurality of parts, in order to prevent these mistakes, an identifier such as a bar code that can uniquely identify the parts that are filled in the reel is attached in advance and the empty space is replaced. The bar code of the reel and the bar code of the supply reel are mutually checked using a mobile terminal having a bar code reading function (two-point verification). Or, by using a bar code form in which the supply position and the part number of the parts mounted on the board are printed with a bar code, the form bar code, the empty reel bar code, and the supply reel bar code can be mutually checked. Is being performed (3-point verification).

For example, in the three-point verification shown in FIG. 8, the reel (empty reel 107 and the supply reel 108) to which the label of the bar code 109 is attached in advance and the bar code form 1 are attached.
02 and are used. In addition, in the memory of the portable terminal 1 that can read the barcode, data that associates the supply position of the component mounted on the board with the barcode of the product number is stored in advance. First, when the mounting equipment is stopped, the operator key-inputs the supply position number of the component to be supplied, which is displayed on the screen, to the portable terminal 1 or the barcode form 10
2 is used and the barcode of the product number corresponding to the supply position of the component is read and input to the mobile terminal 1. next,
The operator reads the bar code 109 attached to the empty reel 107. When the two barcodes are read, these barcodes (the barcode of the component to be replenished and the barcode 109 of the empty reel 107 are read in the mobile terminal 1.
And) are compared (matched). Here, if the two bar codes are different (bar code error), the fact that the bar code is collated is displayed on the mobile terminal 1 and the operator is prompted to read the bar code of the correct empty reel again. . On the other hand, if the two barcodes match, the worker
Then, the bar code 109 on the supply reel 108 is read. Then, in the mobile terminal 1, the barcode 109 on the supply reel 108 is compared with the above two barcodes.
If the three bar codes are different, the fact that the bar code collation has failed is displayed on the mobile terminal 1 and the operator is prompted to read the bar code of the correct supply reel again.
This collation result can be read out from the mobile terminal 1 as history data together with the working time, and can be managed in an external storage unit (not shown). By such three-point matching,
This prevents mistakes in the supply reel and supply location when replacing parts.

The two-point collating method of collating only the bar code of the empty reel and the bar code of the supply reel without using the bar code form is easier than the three-point collating method. However, this two-point matching method has a problem that the system is determined to be correct even if the reel adjacent to the reel to be exchanged is mistakenly exchanged.

[0007]

However, in the above-mentioned conventional three-point matching, the following problems occur. First,
If the barcodes of the parts to be replenished and the barcodes of the empty reels are correctly collated, and there are many errors in collating the barcodes of the replenishment reels, the operator mistakenly reads the barcodes of the empty reels again. Even if it happens, the collation is determined to be correct on the system. Secondly, when there is almost no remaining number of parts on the reels adjacent to the reel that has run out of parts, an operator may replace the two reels at the same time. In this case, even if the operator mistakenly loads the two supply reels in the opposite positions from the correct positions, the system determines that the supply is correct. in this way,
In the conventional part replacement method, there is a possibility that an operator may load the reel of the wrong part.

Therefore, it is an object of the present invention to maintain and analyze the history of material (or part) replacement (replenishment) procedures, and even if wrong materials or parts are replaced, a phenomenon that may cause an error is identified. An object of the present invention is to provide a material exchange monitoring method and system capable of producing a high quality product by appropriately outputting or displaying.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the case where the material exchange monitoring method provided by the present invention is applied to mounting equipment for mounting electronic parts on a printed circuit board will be described as an example. Figure 1
FIG. 1 is a block diagram showing a configuration of a material exchange monitoring system according to an embodiment of the present invention. 1, the material exchange monitoring system according to the present embodiment includes a mobile terminal 1, a relay device 2, an input processing unit 3, a history database 4, a rule database 5, a search processing unit 6, and a display output unit. 7 and 7. First, the outline of each component of the material exchange monitoring system according to the present embodiment will be described.

The mobile terminal 1 has a bar code reading function capable of reading a bar code label attached to a reel of parts, and is capable of inputting numbers and the like from a ten-key pad. Further, the portable terminal 1 carries out a matching operation of the read barcode and holds all or a part of the matching information, and transmits the matching information wirelessly or by wire as necessary. The relay device 2 relays the matching information transmitted from the mobile terminal 1 to the input processing unit 3. The general repeater 2 receives the collation information transmitted from the plurality of mobile terminals 1 as a wireless signal or a wired signal and transmits it to the input processing unit 3 via the network. Note that the collation information may be directly transmitted from the mobile terminal 1 to the input processing unit 3 by a dedicated line without using the repeater 2. The input processing unit 3 processes the collation information transmitted via the relay device 2, stores it in the history database 4, and manages it. The rule database 5 holds and manages rule information that induces a component replacement error in advance. The search processing unit 6 searches whether the content corresponding to the rule information managed by the rule database 5 exists in the collation information managed by the history database 4. Then, the search processing unit 6 outputs the search result to the display output unit 7. The display output unit 7 displays the search result given from the search processing unit 6 on the screen.

Next, with reference to FIGS. 2 to 6, a concrete process of each component of the material exchange monitoring system according to this embodiment will be described. FIG. 2 is a flowchart showing the procedure of the barcode matching process performed by the mobile terminal 1. FIG. 3 is a diagram showing an example of the data structure of the history database 4. Figure 4
FIG. 3 is a diagram showing an example of a data structure of the rule database 5. FIG. 5 is a flowchart showing the procedure of the collation information search process performed by the search processing unit 6. FIG. 6 is a diagram showing an example of the search result screen displayed on the display output unit 7.

First, referring to FIG. 2, the bar code collating process performed by the portable terminal 1 will be described. When the mounting equipment runs out of parts and the supply position of the part is displayed on the screen, the operator inputs the supply position of this part (part to be replenished) from the ten-key pad to the portable terminal 1 (step S20).
1). The mobile terminal 1 confirms whether the input supply position is the supply position (effective supply position) defined by the mounting equipment (step S202). Here, if the input supply position is not the effective supply position, the mobile terminal 1 determines that the supply position of the component has been input incorrectly, and stores the state of “supply position error” together with the date and time when the error occurred ( Step S203).

On the other hand, when the portable terminal 1 confirms that the input supply position is the effective supply position, the worker reads the bar code of the empty reel (step S204). The mobile terminal 1 acquires the bar code of the component corresponding to the input supply position based on the data that associates the supply position of the component and the bar code of the product number, which are held in advance, and acquires the barcode and the empty reel. It is checked whether or not the barcode matches (step S205). If the two barcodes do not match, the mobile terminal 1 determines that the barcode for the wrong component has been input, that is, the empty reel to be replaced is incorrect, and the date and time when the error occurred will cause a “misread” error. The state "(1)" is stored (step S20).
6). Further, the mobile terminal 1 stores attribute information such as a wrong part number of the empty reel as necessary (step S2).
06). After that, the mobile terminal 1 displays "misread (1)"
It is further determined whether or not the state has reached a predetermined number of times (step S207), and if not reached, the operator is requested again to read the bar code of the correct empty reel (step S204). It should be noted that step S207 is performed in order to forcibly terminate the process before the action has a great influence on the manufacturing when a wrong input is repeatedly made, and a predetermined reference serving as a determination criterion. The number of times can be freely set in consideration of the influence of the action.

When the portable terminal 1 confirms that the two barcodes match in step S205, the worker:
Next, the bar code of the supply reel is read (step S2
08). Then, the mobile terminal 1 checks whether the barcode of the empty reel and the barcode of the supply reel match (step S209). If the two barcodes do not match, the mobile terminal 1 determines that the barcode of the wrong component has been input, that is, the supply reel to be replaced is wrong, and the date and time when the error occurred will cause a “misread”. (2) ”is stored (step S21
0). In addition, the mobile terminal 1 stores attribute information such as the part number of the wrong supply reel as necessary (step S).
210). After that, the portable terminal 1 further determines whether or not the "misread (2)" state has reached a predetermined number of times (step S211), and if the number has not reached, a correct reading of the bar code of the supply reel is performed again by the operator. Request (step S208). The determination in step S211 is made for the same reason as in step S207. When it is confirmed in step S209 that the two barcodes match each other, the mobile terminal 1 determines that normal component replacement has been performed, and stores the state of "normal end" together with the date and time (step S212).

Then, in the portable terminal 1, when the component replacement is normally completed (step S212), the component supply position is erroneously input (step S203), and the misreading of the empty reel continues for a predetermined number of times. (Step S2
07, Yes) and when the mistaken reading of the supply reel continues for a predetermined number of times (Yes in step S211), all the states and the date and time stored until then are used as collation information together with the route number of the last process. It is transmitted to the input processing unit 3 (step S213). When the barcode collation processing is completed in the mobile terminal 1, the input processing unit 3 registers the collation information transmitted from the mobile terminal 1 in the history database 4.

Depending on the mounting equipment, a reel of components is filled in a predetermined cassette (or tray) and installed at the component supply position. In such a mounting facility, there is a case where a specific component is not filled in the same predetermined cassette due to replacement of the cassette or the like. Therefore, as a measure against such a case, a barcode label with a unique cassette ID may be attached to each cassette in advance, and the barcode of the cassette may be further collated after the barcode of the supply reel is collated. Then, the bar code collation state of this cassette may be registered in the history database 4 as collation information.

Next, the data structure of the history database 4 will be described with reference to FIG. In the history database 4,
The items of the operation number 31, the component supply position 32, the route number 33, the date and time of occurrence 34, the state 35, and the attribute 36 are managed based on the collation information transmitted from the mobile terminal 1. The operation number 31 stores a serial number assigned as a unit of collation information (a series of operations performed for a certain part out) transmitted from the mobile terminal 1, and is used for information management of the operator. Therefore, when a plurality of work mistakes occur during the work for a certain component shortage, a plurality of the same operation numbers (“1” in the example of FIG. 3) exist. The component supply position 32 stores the number of the supply position of the mounting equipment that the worker has targeted for component replacement. Route number 33
2, the route number of the final process that has reached step S213 is stored in the field. The date and time of occurrence 34 stores the date and time when an error in component replacement occurred or the date and time when component replacement was performed normally. The state 35 stores the state (error of component replacement or normal end) that occurred at the date and time indicated by the date and time of occurrence 34. The attribute 36 stores necessary attribute information such as the misread part number.

Next, the data structure of the rule database 5 will be described with reference to FIG. In the rule database 5, rule number 41, application 42, condition 43, condition attribute 4
4 and the occurrence display 45 are managed in advance as rule information. The rule number 41 stores an identification number that identifies a predetermined rule. The application 42 stores an instruction as to whether or not to apply the rule to the matching information search. The condition 43 stores the condition of the rule determined in the search of the matching information. Condition attribute 4
4 stores predetermined attribute information (threshold value, etc.) serving as a criterion for judging the rule condition. In the occurrence display 45,
The contents to be displayed on the screen of the display output unit 7 when the existence of the corresponding rule is confirmed by the search of the collation information are stored.

In the example shown in FIG. 4, the following rule information is managed. As the rule number 1, a rule is defined regarding how many times the state of "misread (1)" is repeated in succession, and when it is repeated three times or more, a warning "an empty reel miss occurs" is issued. It is set. As the rule number 2, a rule is defined regarding how many times the state of "misreading (2)" is repeated in succession, and when repeated three times or more, a warning "replenishment reel error occurs" is issued. It is set. Further, as the rule number 3, a rule regarding whether or not "simultaneous exchange of two reels" is performed is defined, and the exchange time T1 of one reel and the exchange time T2 of the other reel are defined.
If and are within | T1-T2 | <60 seconds, the warning that "simultaneous exchange of materials occurs" is set. In addition, as a correspondence to the case of using the above-mentioned cassette, the rule regarding the "relationship between the cassette and the filled parts" is defined in the rule number 4, and the cassette ID and the replaced part number are different from the previous relationship. If it is, the warning that "the product number does not match the cassette ID" is issued. In addition, rule number 5
As a rule regarding "out of parts" is stipulated,
If there is a remaining number of parts (required by subtracting the number used at the equipment from the initial number at the time of replacing the parts), it is set to issue a warning "There is still a remaining number of parts" . Note that these rules are merely examples, and various rules other than this can be freely defined.

Next, referring to FIG. 5, the search processing of the matching information based on the rule information performed by the search processing unit 6 will be described. This search process is automatically performed on a regular basis. First, the search processing unit 6 specifies the search range of the collation information managed by the history database 4 (step S50).
1). The designation of the search range is usually performed retroactively from the latest data of the occurrence date / time 34. However, if necessary, the operator can select and specify the search range. In FIG. 5, the search range is represented by the operation number 31 for the sake of simplicity (N to N + M). Next, the search processing unit 6 determines whether or not the rule information of the rule database 5 corresponds to the matching information of the operation number N which is the first in the search range (steps S502 and S50).
3). Here, the search processing unit 6 uses the rule database 5
Only the rule for which the item of application 42 is “yes” is applied. Then, when it is confirmed as a result of the search that the rule corresponding to the collation information of the operation number N is present, the search processing unit 6 outputs the rule occurrence display 45 to the display output unit 7 (step S504). The search processing of steps S503 and S504 is performed for all collation information (operation numbers N to N + M) in the specified search range (steps S505 and S506).

Finally, with further reference to FIG. 6, the corresponding rule information retrieved by the retrieval processing unit 6 is displayed on the display output unit 7.
An example displayed on the screen will be described. The information displayed on the screen is the operation number 61, the parts supply position 62, and the date and time of occurrence 6
3. Occurrence display 6 registered in the rule database 5
4, an attribute 65, a confirmation registration 66 for confirming a collation error by an operator, an empty reel part number 67, a supply reel part number 68, and an operator 69. Normally, this information is displayed in order from the latest occurrence date and time. In this embodiment, by operating the scroll bar 70, it is possible to refer to past information that cannot be displayed on the screen. Further, by operating the detail button 71, the detailed content of the selected information, for example, the content of the history database 4 shown in FIG. 3 can be confirmed. Also,
The display range is linked to the search range described earlier,
Updated regularly. Further, the search range can be input in the input field 72.

As described above, according to the material replacement monitoring method and system according to the embodiment of the present invention, a mistake in the parts (materials) collation occurs in the portable terminal 1 due to an error in the operation procedure performed by the operator. In this case, the result indicating the possibility (suspecting) of a component collation error is sequentially displayed on the display output unit 7 based on the predetermined rule information. This makes it possible to reduce quality loss and manufacture high-quality products.

In the above embodiment, the case where the search result output from the search processing unit 6 is displayed on the screen of the display output unit 7 has been described. However, in addition to this, as shown in FIG. 7, a signal output unit 10 that converts the search result output from the search processing unit 6 into a signal format according to the external mounting equipment 11 and outputs the signal is further provided. The search result may be displayed on the screen of the equipment 11 side, or the mounting equipment 11 may be directly controlled (operation is stopped).
