Description

  The present invention relates to an apparatus and method for counting the quantity of a plurality of parts stored in a storage body, and more particularly to an apparatus and method for counting the quantity of parts stored in a series of tapes.

  For example, an electronic component storage body as shown in FIG. 12 is mounted on a component mounter that mounts electronic components on a substrate. The component mounting machine can manufacture a product at high speed by holding in advance a large number of electronic components housed in such a housing.

  FIG. 12 is a diagram showing an overview of a tape that holds an electronic component. As shown in the figure, the electronic component 2 is housed in a series of tapes 4 wound on a reel 1.

  The tape 4 that holds the electronic component 2 is mounted on a component mounter together with the reel 1. The component mounter manufactures a product by sequentially removing the electronic component 2 from the cavity and mounting it on a substrate or the like while peeling off the film 5 attached to hold the electronic component 2 on the tape 4. .

Here, terms are defined.
Hereinafter, “product” includes intermediate products. “Tape” refers to a band-shaped member for housing components. “Cavity” refers to a recess on the surface of the tape for storing components one by one. A “reel” refers to a member for winding a tape. The “component reel” means a reel in which a tape holding a component is wound.

  In general, the component mounting machine is not a dedicated machine for manufacturing a specific product, but a general-purpose machine capable of manufacturing a plurality of types of products. Therefore, when switching from one type of product to production of a different type of product with a single component mounter, the component reel is often replaced. At this time, a component reel that has been used halfway is generated.

  When the component mounter starts manufacturing, the number of components held by the component reel to be mounted is input to the component mounter so that the component will not run out in the middle. For this input, the number of parts held by the part reel in use is required. In addition, the same quantity of parts is required for inventory for checking the parts inventory of the mounting line.

Conventionally, a component counting device 10 as shown in FIG. 13 has been proposed as a device for counting the components held by a component reel (see, for example, Patent Document 1). The component counting apparatus 10 shown in the figure detects the feed round holes of the tape and counts the detected round holes.
Japanese Utility Model Publication No. 4-73276

However, the conventional component counting apparatus has a problem that it takes time to count the components.
For example, in the conventional component counting apparatus 10 shown in FIG. 13, a component reel is mounted on one of the shafts 11 and an empty reel is mounted on the other, and the number of feed holes formed in the tape is counted while winding the tape. Thus, the number of parts stored in the part reel is counted. Therefore, the conventional component counting apparatus 10 requires at least the time required to wind the component reel tape while counting the number of holes and to rewind the tape to the state before counting.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a component counting device that can easily count components held on a component reel in a short time.

  In order to achieve the above object, a component counting device according to the present invention is a component counting device that counts components contained in a component reel, which is a reel on which a tape for holding a component is wound. From the weight acquisition means for acquiring the weight, and the weight of the component reel acquired by the weight acquisition means, the weight of the part not holding the component included in the tape wound on the component reel and the weight of only the reel By subtracting, the component tape weight calculating means for calculating the weight of the part holding part including the part included in the part reel and the tape of the part holding the part, and the part tape weight calculating means A quantity calculating unit that calculates the quantity of parts included in the part reel by dividing the total weight by a unit weight that is a weight of a part holding part of one unit number. Provided with a door.

  Thus, the total weight of the parts included in the part reel and the tape holding the part is calculated by subtracting the weight of the remaining members registered in advance from the weight of the part reel. From the total weight, the parts contained in the part reel are counted. Therefore, there is no need to remove the wound tape from the component reel, and the components held by the component reel can be counted as they are. Therefore, it is possible to easily and quickly count the number of parts held by the component reel in use, which is necessary when replacing the component reel mounted on the component mounter or when taking inventory. This makes it possible to save labor.

  In addition, in this way, not only the components but also the components included in the component reel are counted based on the total weight of the components and the tape holding the components. In general, a weight measuring device having a resolution capable of accurately measuring the weight of only one component is expensive. Weight measurement is cheaper than a weight measuring instrument that can accurately measure the weight of only one component by counting the components contained in the component reel based on the weight including not only the component but also the tape that holds it. It is possible to count with high accuracy using a measuring instrument.

  Preferably, the reel information indicating the type of the reel, the weight of the empty part that does not hold the parts included in the unused tape, and the reel information in which the weight of the reel is associated with each other are stored. The component tape weight calculating means further refers to the reel information to obtain a reel code related to the component reel for which the weight acquired by the weight acquiring means is measured. The associated weight of the empty part and the weight of only the reel are acquired, and the total weight is calculated by using the acquired weight of the empty part as the weight of the part not holding the part.

  Thus, the weight of the empty part for each type of reel and the weight of only the reel are stored. Therefore, the reel weight for calculating the weight reduced by the use of parts can be changed according to the type of reel. Therefore, it is possible to improve the accuracy of component counting.

  More preferably, it further comprises a component code acquisition means for acquiring a component code, the component information storage means further stores the component information associated with the reel code, and the component tape weight calculation means further includes The reel information associated with the component code obtained by the code obtaining means is obtained by referring to the component information, and the reel code associated with the obtained reel code is obtained by referring to the reel information. The unit that is associated with the component code acquired by the code acquisition unit by referring to the component information by acquiring the weight of the empty part and the weight of only the reel, and the quantity calculation unit further refers to the component information Get weight.

  In this way, information in which the type of component is associated with the reel code is stored. For the component reels that hold the same type of component, the weight reduced due to the use of the component is calculated using the weight of the empty portion related to the same reel type and the weight of only the reel. Therefore, if the component reels hold the same type of components, the total of the components held by the plurality of component reels can be counted simultaneously. Therefore, it is possible to easily count the number of components in a short time, and it is possible to save labor required when exchanging the component reels mounted on the component mounting machine.

  More preferably, the apparatus further includes a component registration unit that calculates the unit weight, associates the calculated unit weight with a component code indicating a component type, and stores the unit weight in the component information storage unit.

  Further, the information processing apparatus further includes input means for input by a user, wherein the part registration means includes a part code acquired by the part code acquisition means, a weight of an unused part reel acquired by the weight acquisition means, and the input means. And the rated quantity which is the quantity of the parts included in the unused part reel input to the reel part, and the weight of the empty part and the weight of only the reel associated with the obtained part code are obtained as the reel information. The component code acquisition means is obtained by dividing the weight obtained by subtracting the weight of the empty part and the weight of only the reel from the weight of the unused component reel by the rated quantity. The unit weight of the component indicated by the acquired component code is calculated, and the calculated unit weight is stored in the component information storage unit in association with the type of component.

  Thus, the unit weight of a part is calculated from the acquired various quantities. Therefore, the labor for registering the unit weight is reduced as compared with the case of inputting the unit weight itself, and the convenience of the user can be improved.

  In addition, since the calculated unit weight is registered in association with the type of part, the unit weight is calculated or entered each time the part reel part holding the registered type part is counted. It is possible to save the user's trouble.

  More preferably, the counting history information storage unit stores counting history information in which the quantity calculated by the quantity calculating unit is associated with a component code indicating the type of component included in the counted component reel, Display control means is provided for counting the quantity included in the counting history information for each part code and displaying the total quantity for each part code on a display device.

  In this way, the total quantity for each type of part is displayed. In general, the quantity for each type of part is required when taking inventory. For this reason, it is possible to improve the convenience for the user by displaying the quantity counted for each type of component.

  The present invention can be realized not only as a component counting apparatus including such characteristic means, but also as a component counting method using the characteristic means included in the component counting apparatus as a step. It can also be realized as a program that causes a computer to function as characteristic means included in the counting device. Such a program can be distributed via a recording medium such as a CD-ROM (Compact Disc-Read Only Memory) or a communication network such as the Internet.

  According to the present invention, it is possible to easily and quickly count the number of parts held by a part reel that has been used halfway. Therefore, it is possible to save labor required for exchanging the component reels mounted on the component mounting machine or taking inventory.

  Hereinafter, an embodiment of a component counting device according to the present invention will be described with reference to the drawings.

  First, the configuration of a component counting device according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a diagram showing an outline of the configuration of a component counting system according to an embodiment of the present invention. The component counting system 100 shown in the figure includes a component reel 140, a weight measuring device 130, a barcode reader 120, and a component counting device 110.

The component reel 140 is a reel on which a tape for holding a component is wound.
The weight measuring device 130 is a device for measuring the weight, and the weight measuring device 130 of the present embodiment is used for measuring the weight of the component reel 140 and the weight of the reel. A specific example of the weight measuring device 130 is an electronic balance. In order to count electronic components, the weight measuring device 130 having a resolution of about 1 mg to 10 mg is desirable.

  The barcode reader 120 is a device for reading a barcode. Bar code reader 120 of this embodiment reads a bar code attached to the surface of a reel. The component counting device 110 according to the present embodiment uses information obtained from the barcode reader 120 in order to specify the component reel 140 to be counted by type.

  The component counting device 110 is a device that counts the components included in the component reel 140, and counts the number of components from the total weight of the component reel 140 acquired from the weight measuring device 130.

  FIG. 2 is a diagram showing details of the component reel 140. The component reel 140 includes a reel 142 and a tape 146.

  A barcode 144 is written on the reel 142, and in this embodiment, a label with the barcode 144 is affixed to the surface of the reel, and the component held by the component reel 140 is attached to the barcode 144. The information indicating the type is marked. More specifically, for example, information indicating the manufacturer of the component reel 140 to which the barcode is attached and the type of the component are marked on the barcode 144 of the present embodiment. The bar code reader 120 is used for reading the information of the bar code 144.

  The tape 146 is an example of a holding member for holding a component. The tape 146 includes a component holding portion that holds the component and an empty portion that does not hold the component. A boundary 148 indicates a boundary between the component holding portion and the empty portion.

  The empty portions are generally included at both ends of the tape 146 when not in use. In general, in the case of the unused tape 146, the component mounting machine sucks and mounts a component housed in a cavity at a certain distance from the end of the tape 146 and mounts it on the substrate. When the component reel 140 is replaced, the tape is cut leaving a certain length of the empty portion from the component suction position due to the structure of the feeder that feeds out the tape. Therefore, even in the case of the component reel 140 being used, an empty portion having the same length as that of the tape 146 when not in use is left on the tape wound around the reel.

  The component unit 160 is a total of a unit quantity of components and a tape that holds the components. In the component unit 160 of the present embodiment, the unit quantity is one. Therefore, the part holding portion can be said to be a collection of part units 160 corresponding to the number of parts held by the entire tape 146.

  FIG. 3 is a block diagram showing the configuration of the component counting apparatus according to the embodiment of the present invention. The component counting device 110 is a device that counts the number of components included in the component reel, and is realized by, for example, a general-purpose computer.

  In the component counting apparatus 110 shown in the figure, a barcode reader 120, a weight measuring device 130, an input unit 170, and an output unit 180 are connected to the outside. In addition, the component counting apparatus 110 shown in the figure includes a component reel storage unit 200, a count history storage unit 202, a clock unit 204, a reel registration unit 206, a component code acquisition unit 208, and a component registration determination. Unit 210, weight acquisition unit 212, component registration unit 214, quantity calculation unit 216, and display control unit 218.

  Since the bar code reader 120 and the weight measuring device 130 are the same as the devices having the same reference numerals in FIG. 1, the description thereof is omitted here. The input unit 170 is an input device such as a keyboard or a mouse. The output unit 180 is a display device such as a monitor or a printer.

  The component reel storage unit 200 stores reel information 200a that is information about reels and component information 200b that is information about components.

  FIG. 4 is a diagram illustrating an example of the reel information 200a stored in the component reel storage unit 200. The reel information 200a shown in this figure includes a reel type, a reel weight, a tape end weight, and a correction weight.

  In the reel type, a reel code that is information for specifying the type of the reel is stored. In the reel weight, the weight of only the reel is stored.

  The weight of both ends of the tape stores the weight of the empty portion included in the tape wound around the component reel. In the present embodiment, the weight at both ends of the tape is the weight of the empty portion included in the tape 146 wound around the component reel 140 when not in use.

The correction weight stores a weight for correcting the weight of the component reel.
As a specific example stored in the correction weight, the weight of a label or the like with a barcode 144 attached to the component reel 140 is given. In order to prevent the component mounting machine from running out of parts, it is desirable to estimate the number of parts contained in the part reel to be small so that a warning can be issued before the parts run out. In the component counting apparatus 110 according to the present embodiment, by appropriately setting the correction weight, it is possible to prevent the component quantity from being counted more than actual. Therefore, it is possible to prevent the occurrence of component breakage when using a component reel in use.

  In this figure, for example, for a reel whose “reel type” is “R01”, “reel weight” is “41.64” g, “tape both end weight” is “0.85” g, and “correction” An example including reel information whose “weight” is “0.00” g is shown.

  FIG. 5 is a diagram illustrating an example of the component information 200b stored in the component reel storage unit 200. The component information 200b shown in the drawing includes a component code, a rated quantity, a reel type, a new total weight, and a component single weight.

  The component code stores a component code that is information for identifying the type of component. The rated quantity stores the quantity of parts included in the parts reel when not in use. In the reel type, a reel code indicating the type of reel used for the type of component indicated by the component code is stored. The total weight of the parts reel when not in use is stored in the new total weight. In the component single weight, the total weight of the component corresponding to a predetermined quantity and the tape holding the component is stored.

  In this embodiment, the predetermined quantity is one. Therefore, the component single weight of the present embodiment is the weight of the component unit 160.

  In the figure, for example, for a part whose “part code” is “A-P01”, the “rated quantity” is “3000”, the “reel type” is “R01”, and the “new product gross weight” is An example including part information of “112.29” g and “part single weight” of “0.0233” g is shown.

Returning to FIG. 3 from here.
The count history storage unit 202 stores count history information 202a including the counted history.

  FIG. 6 is a diagram illustrating an example of the count history information 202a stored in the count history storage unit 202. The count history information 202a shown in this figure includes a part code, the number of reels, the total weight, the part quantity, and the registration date and time.

  The component code stores the component code of the component included in the component reel to be counted.

  The number of reels stores the number of component reels to be counted. When counting the total number of parts included in a plurality of part reels, the type of parts included in the part reels must be the same.

The total weight stores the total weight of the measured component reels.
The number of parts counted is stored in the part quantity.

  The date and time when each counting history is stored is stored in the registration date and time. In this embodiment, an example is shown in which the registration date is information in minutes, but information in seconds may be stored.

  This figure shows, for example, the history of the part whose part code is “A-P01” counted at “17:00 on July 1, 2006” indicated by “registration date / time”, and “reel number” is “ An example including count history information of “1”, “gross weight” of “50.69” g, and “part quantity” of “352” is shown.

Returning to FIG. 3 from here.
The clock unit 204 holds the current date and time.

  The reel registration unit 206 stores the reel information 200 a in the component reel storage unit 200. The reel registration unit 206 according to the present embodiment associates the reel code acquired from the input unit 170, the tape end weight, the correction weight, and the weight of only the reel 142 acquired from the weight measuring device 130, and stores the component reel. Stored in the unit 200.

  The component code acquisition unit 208 acquires a component code output from the barcode reader 120 that has read the barcode 144 attached to the reel 142 of the component reel 140.

  The component registration determination unit 210 determines whether or not the component code acquired by the component code acquisition unit 208 is already registered in the component information 200b by referring to the component information 200b.

  The weight acquisition unit 212 acquires the weight of the component reel 140 measured by the weight measuring device 130.

  The component registration unit 214 stores, in the component reel storage unit 200, the component information 200 b related to the component code acquired by the component code acquisition unit 208 when the component registration determination unit 210 determines that it is not registered.

  The component registration unit 214 of the present embodiment acquires the component code acquired by the component code acquisition unit 208 via the component registration determination unit 210, and acquires the rated quantity and reel type input to the input unit 170. The new total weight, which is the weight of the unused component reel, is acquired via the weight acquisition unit 212, the component single weight is calculated by itself from the acquired quantity, and the component information 200b in which these are associated is stored in the component reel storage unit To store.

  In order to calculate the component single weight, the component registration unit 214 acquires the reel information 200a associated with the reel type acquired by itself, and corrects the tape end weight and the reel weight included in the reel information 200a from the new total weight. Subtract the weight and divide the result by the rated quantity.

  The quantity calculation unit 216 acquires the component code acquired by the component code acquisition unit 208 via the component registration determination unit 210 when it is determined as already registered by the component registration determination unit 210, and is associated with the component code. Component information 200b, reel information 200a associated with the reel type included in the component information 200b, the number of reels acquired from the input unit 170, and the weight of the component reel acquired by the weight acquisition unit 212. The number of parts contained in the part reel is counted. Then, the quantity calculation unit 216 stores the weight of the component reel, the component quantity calculated by itself, the number of reels, and the date and time acquired from the clock unit 204 in the count history storage unit 202 in association with each other.

  In order to count the components, the quantity calculation unit 216 first subtracts the tape end weight, the reel weight, and the correction weight included in the reel information 200a from the weight of the component reel acquired by the weight acquisition unit 212, thereby generating a component reel. The total weight of all the parts included in the whole and the tape of the part holding those parts is calculated. Next, the quantity calculation unit 216 divides the calculated total weight by the component single weight included in the component information 200b. As a result, the quantity calculation unit 216 calculates the quantity of components included in the component reel to be counted.

  Here, when counting the number of parts included in a plurality of part reels at a time, that is, when the number of reels acquired from the input unit 170 is two or more, the weight of the component reels acquired by the weight acquisition unit 212. From this, the weight obtained by multiplying the total of the tape end weight, the reel weight, and the correction weight by the number of component reels to be counted is subtracted.

  That is, the quantity calculation unit 216 corresponds to the part tape weight calculation unit and the quantity calculation unit of the present invention.

The display control unit 218 causes the output unit 180 to display information.
According to the component counting apparatus 110 described above, the operation required by the user for counting the components is to place the component reel on the weight measuring device 130 as it is, and to move the barcode on the component reel with the barcode reader 120. Easy operation such as reading. Therefore, the parts counting device 110 of the present embodiment can count the parts included in the part reel from the weight of the part reel. In addition, in the component counting apparatus 110 of the present embodiment, the number of components included in a plurality of component reels with the same component code can be counted simultaneously.

  Therefore, it is possible to easily and quickly count the number of parts held by the part reel that has been used halfway. Therefore, it is possible to save labor required for exchanging the component reels mounted on the component mounting machine.

  Next, with reference to FIG. 7 and FIG. 8, a process executed by the component counting apparatus 110 according to the embodiment of the present invention will be described.

  FIG. 7 is a flowchart showing an example of processing executed by the component counting apparatus according to the embodiment of the present invention.

  The component code acquisition unit 208 acquires the component code read by the barcode reader 120 from the barcode 144 on the component reel 140 (S101).

  The component registration determination unit 210 determines whether or not the component code acquired in the component code acquisition process (S101) is already registered in the component information 200b by referring to the component information 200b (S102).

  If it is determined that it has not been registered, that is, it has not been registered (No in S102), the component registration unit 214 executes component registration processing (S103).

  When it is determined that it has been registered, that is, it is already registered (Yes in S102), the weight acquisition unit 212 acquires the total weight of the component reels measured by the weight measuring device 130 (S104).

  Here, the total weight of the component reels acquired in the total weight acquisition step (S104) includes the weight of the empty portion of the tape 146 generated due to the structure of the feeder as described above. In addition, the weight of the empty portion that is subtracted to calculate the weight of the component holding portion of the tape 146 is the weight of the empty portion included in the tape 146 when not in use.

  Since the weight per part is lighter than the weight of the tape, the difference in weight between the empty part of the tape when not in use and the empty part of the tape in use can cause an error in counting the parts. Such an error in counting the parts due to the difference in the weight of the empty portion of the tape is often within an allowable range for operation.

  If this error becomes a problem, the difference in weight between the empty portion of the unused tape 140 and the empty portion of the tape 140 in use is set in the “corrected weight” of the reel information 200a. By cutting the length of the empty portion of the tape 140 in accordance with the length of the empty portion of the tape 140 when not in use, it is possible to reduce the component counting error caused by the difference in the weight of the empty portion of the tape. it can.

From here, it returns to description of FIG.
Based on the total weight acquired by the weight acquisition unit 212, the component code acquired by the component code acquisition unit 208, the component information 200b and the reel information 200a related thereto, the quantity calculation unit 216 performs the above-described component counting. By the above calculation, the number of parts included in the part reel is calculated (S105).

  The quantity calculation unit 216 stores the count history information 202a including the calculated quantity in the count history storage unit 202 (S106).

  The display control unit 218 displays the screen on the output unit 180 based on all the count history information 202a stored in the count history storage unit 202, including the count history information 202a stored in the count history storage process (S106). Update (S107) and end the process.

FIG. 8 is a flowchart showing details of the component registration process (S103) shown in FIG.
The display control unit 218 causes the output unit 180 to display a registration screen for the component information 200b based on the output from the component registration unit 214 (S201).

  The component registration unit 214 acquires the rated quantity of component reels to be registered, which is input by the user with reference to the display of the output unit 180, from the input unit 170 (S202).

  The component registration unit 214 acquires the reel code of the component reel to be registered, which is input by the user with reference to the display of the output unit 180, from the input unit 170 (S203).

  The component registration unit 214 acquires a new total weight, which is the weight of an unused component reel, from the weight acquisition unit 212 (S204).

  In response to the instruction input by the user to the input unit 170, the component registration unit 214 receives the rated quantity acquired in the rated quantity acquisition process (S202), the reel code acquired in the reel code acquisition process (S203), and the unused code. Component information in which the total new weight acquired in the total weight acquisition process (S204) and the component single weight calculated by itself are associated with the component code acquired by the component code acquisition unit 208 in the component code acquisition process (S101). 200b is stored in the component reel storage unit 200 (S205).

  As described above, the component single weight is obtained by acquiring the reel information 200a associated with the reel type acquired by itself, and calculating the weight of both ends of the tape, the reel weight, and the correction weight included in the reel information 200a from the total new weight. The parts registration unit 214 calculates by subtracting and dividing the subtracted result by the rated quantity.

  The display control unit 218 updates the screen display on the output unit 180 with the newly registered component information 200b (S206), and ends the process.

  Thereby, the user can register information related to the new component code. Also, the registered information can be confirmed on the screen immediately after.

  Furthermore, an example of a screen displayed on the output unit 180 by the component counting device 110 according to an embodiment of the present invention will be described with reference to FIGS. 9 to 11.

FIG. 9 is a diagram showing a display example of a screen for registering the reel information 200a.
The reel type included in the reel information registration screen 300 shown in the figure is input from the input unit 170 by the user. This reel type corresponds to the “reel code” of the reel information 200a. This figure shows an example of registering reel information related to a reel whose reel type is “R02”.

  The reel weight is automatically input by the user measuring the reel using the weight measuring device 130. Furthermore, the “tape both end weight” and “correction weight” presented in a table format are input from the input unit 170 by the user. “Tape both end weight” and “correction weight” respectively correspond to “tape both end weight” and “correction weight” of the reel information 200a.

  After the information is input, when the user presses the registration button 302, new reel information included in the reel information registration screen 300 is stored in the reel information 200a of the component reel storage unit 200. Also, new reel information input by the user pressing the cancel button 304 is not stored in the component reel storage unit 200, and registration is cancelled.

  By inputting from such a screen, the user can register information on a new reel. Further, since the reel weight is automatically input from the weight measuring device 130, an accurate and simple input is possible.

FIG. 10 is a diagram showing a display example of a screen for registering the component information 200b.
The component code included in the component information registration screen 310 shown in the figure is automatically input based on information read by the barcode reader 120. This figure shows an example of registering part information related to a part whose part code is “A-P01”.

  Then, the “rated quantity” and “reel type” presented in a table format are input from the input unit 170 by the user. The “new total weight” is automatically input by the user measuring the weight of the unused reels using the weight measuring device 130. The “part single weight” is automatically calculated and inputted by the part counting device 110.

  When the user presses the registration button 312 after these pieces of information are input, new component information included in the component information registration screen 310 is stored in the component information 200b of the component reel storage unit 200. Also, new component information input by the user pressing the cancel button 314 is not stored in the component reel storage unit 200, and registration is cancelled.

  FIG. 11 is a diagram illustrating an example of a screen for displaying the counting history information 202a. In the counting result display screen 320 shown in the figure, “details” information is presented on the left side of the screen, and “total” information is presented on the right side of the screen in a table format.

  The “detail” information is a part for displaying each of all the count history information 202 a stored in the count history information storage unit 202. For example, this figure is an example in the case where three pieces of counting history information 202a are stored in the counting history information storage unit 202.

  The “details” information in this figure indicates that one component reel whose component code is “A-P01” is counted as “July 1, 2006 14:00”. In addition, “details” information indicates that two component reels with the component code “A-P02” are “July 1, 2006 14:01” and “July 1, 2006 14:05”, respectively. Indicates that it is being counted.

  The “aggregation” information is a part that aggregates and displays all the counting history information 202a stored in the counting history information storage unit 202 by “part code”. For example, when counting parts for inventory, it is convenient if the quantity for each type of parts currently held is collected by such “detailed” information.

  The “aggregation” information in this figure indicates that the number of parts with the part code “A-P01” is “352”. In addition, the “total” information in this figure includes “2292” counted at “14:01 on July 1, 2006” and “July 1, 2006” for the part whose part code is “A-P02”. This indicates that the number is “5734” which is the sum of “3442” counted on “day 14:05”.

  When the user presses the close button 322, the component counting apparatus 110 ends the display of the counting result history information 202a.

  As described above, in the embodiment of the present invention, in order to count the components included in the component reel in use, the total weight of the components included in the component reel in use and the tape holding the components is calculated. Divide by the total weight of the unit quantity of parts registered in advance and the tape holding the parts. The total weight of the component included in the component reel and the tape holding the component is calculated by subtracting the weight of the remaining members registered in advance from the weight of the component reel. In the embodiment of the present invention, the type of component reel is specified by the type of component indicated by a barcode or the like attached to the reel.

  Therefore, a component reel that holds the same type of component can count a plurality of component reels together. Therefore, according to the component counting apparatus of the present embodiment, the user can count the components held on the component reel very easily and in a short time.

  As mentioned above, although the component counting device 110 which concerns on one embodiment of this invention was demonstrated, this invention is not limited to this embodiment.

  For example, in each of the embodiments, the example in which the component is stored in the component reel has been described. However, the component storage body is not limited to the tape wound around the reel. For example, even when the components are stored in the tray, the components held in the tray can be similarly counted from the weight of the tray holding the components.

  Further, even if the reel weight is the weight of the same kind of reel manufactured from the same mold, for example, there is a non-negligible variation in the counting of parts. Therefore, for example, the reel weight of the reel information registration screen 300 shown in FIG. 9 is automatically input instead of or automatically input the reel weight measured using the weight measuring device 130. At the same time, the user may be able to input an average value of the weights of a plurality of reels measured in advance for the same type of reel from the input unit 170.

  Accordingly, it is possible to easily and accurately count the components of the component reel with a more accurate reel weight.

  Further, by measuring the weight of the plurality of reels by the weight measuring device 130 and dividing the result by the number of reels input by the user from the input unit 170, the component counter 110 automatically calculates the average value of the reel weight. , You may enter.

  This facilitates more accurate input of the reel weight, and enables simple and accurate counting of the components on the component reel.

  Further, for example, when the user inputs the reel type on the component registration screen 310 shown in FIG. 10, the component counting device 110 allows the user to select from the already registered “reel code” by referring to the reel information 200 a. May be. By making it possible to select the “reel type” to be input from the already registered “reel code”, erroneous input can be prevented. In addition, since an operation required for input is reduced, efficient input is also possible. Furthermore, the component counting device 110 calculates the “component single weight” by referring to the reel information 200a associated with the “reel code” input to the reel type, so that the user erroneously selects an unregistered reel code. If entered, the component counting device 110 cannot calculate the “component single weight”. Therefore, the “single part weight” can be reliably calculated by preventing such erroneous input.

  The present invention can be applied to an apparatus that counts components stored in a storage body, and in particular, can be applied to an apparatus that counts components contained in a component supply component reel mounted on a component mounter.
