Description

  The present invention relates to a combination weigher and a combination weighing method. More specifically, the present invention relates to a combination weigher and a combination weighing method for performing a combination operation by converting the weight of an object to be weighed into another parameter.

  A combination weigher as disclosed in Patent Document 1 is widely used as a technique for weighing a certain amount of commodities such as food. In combination weighing, generally, weighing is performed so that the weight of an object to be weighed satisfies a predetermined condition. The objects to be weighed are supplied to a plurality of weighing units and weighed. When the weighing is finished, a combination of weighing units in which the total of measured values satisfies a predetermined condition is selected and discharged to the packaging machine.

In combination weighing, conditions other than weight may be set. In retail businesses such as supermarkets, it may be convenient to set conditions for price rather than weight. A combination scale disclosed in Patent Document 2 is a combination calculation performed using the price of an object to be weighed. In this combination weigher, a price condition is set, and the objects to be weighed are supplied to a plurality of weighing units and weighed. Based on the measured value and the unit price, the price of the object to be weighed held in each weighing unit is calculated, and the combination of the weighing units is selected so that the sum of the prices satisfies the set condition.

(First embodiment)
The combination weigher and the combination weighing method of the first embodiment are for producing a food pack in which calories are substantially constant by combining objects to be weighed.
[Device configuration]
FIG. 1 is a perspective view showing an example of a schematic configuration of the combination weigher according to the first embodiment of the present invention. Hereinafter, the hardware configuration of the combination weigher of this embodiment will be described with reference to FIG.

  As shown in FIG. 1, the combination weigher 10 according to this embodiment includes a main body 11, a weighing pan 12 (weighing unit), an indicator lamp 13 (weighing unit indicator lamp), and a panel unit 20 including an input / output device 14. And. The main body 11 has a flat box shape, and weighing pans 12 are arranged on the upper surface thereof in two rows along the longitudinal direction of the main body 11. The number of weighing pans 12 is 6 per row, and the total number of weighing pans is 12. On the upper surface of the main body 11, a total of twelve indicator lamps 13 are arranged corresponding to each weighing pan 12 in the gap between the weighing pans 12 arranged in two rows. A panel portion 20 is disposed at one end of the main body 11 in the longitudinal direction. The panel unit 20 is a flat box shape, and the input / output device 14 is disposed on one main surface. A control board 15 (control device) is stored inside the panel unit 20.

  For example, the weighing pan 12 may have a configuration in which a stainless steel tray is supported by a load cell (not shown). For example, a light emitting diode or a light bulb can be used as the indicator lamp 13. For the input / output device 14, for example, a touch panel is used. In the present embodiment, the input / output device is integrated, but the input device and the output device may be provided separately, or a plurality of input devices or output devices may be provided. The input device may be a button or a microphone. The output device may be a liquid crystal, a buzzer, a speaker, or the like. A plurality of control boards 15 may be provided. That is, the control by the control device may be centralized control or distributed control. A plurality of control devices may have different functions.

  FIG. 2 is a block diagram showing an example of a control system of the combination weigher according to the first embodiment of the present invention. Hereinafter, the control system of the combination weigher of this embodiment will be described with reference to FIG.

As shown in FIG. 2, the control system of the combination weigher 10 according to this embodiment includes a control board 15, an input / output device 14, indicator lights ₁₃₁ to ₁₂ , and weighing pans ₁₂₁ to _12. Yes. The control board 15 includes a control unit 16, a storage unit 17, an indicator lamp drive circuit 18, and an A / D conversion circuit 19. For example, a CPU is used as the control unit 16. For the storage unit 17, for example, an internal memory is used. The control unit 16 and the storage unit 17, and the control unit 16 and the input / output device 14 are connected so as to communicate with each other. The indicator lamp drive circuit 18 is connected to the controller 16 and the indicator lamps ₁₃₁ to ₁₂ so that the indicator lamps ₁₃₁ to ₁₂ can be turned on / off based on a command from the controller 16. The A / D conversion circuit 19 converts the analog signal output from the weighing pans 12 ₁ to 12 based on the detection result into a digital signal and transfers the digital signal to the control unit 16 _{. 12} is connected. The arrow in the figure indicates the direction in which the signal is transmitted.

The outline of the operation of the control board 15 will be described below with reference to FIG. Parameters and the like for determining the combination condition are input from the input / output device 14 to the control unit 16 by a user operation. The control unit 16 stores the received parameters and the like in the storage unit 17.

The storage unit 17 also stores a program for determining combination conditions, a program for performing combination calculations, and the like. Each of the weighing pans _{121 to 12} detects the weight of the object to be weighed and sends the detection result to the A / D conversion circuit 19. The detection results sent from the weighing pans ₁₂₁ to ₁₂ are converted into detection values (digital signals) by the A / D conversion circuit 19 and sent to the control unit 16. The control unit 16 determines the weighing pans ₁₂₁ to 12 that participate in the optimal combination using the received detection value and the program stored in the storage unit 17. Once the optimal combination is selected by the control unit 16, according to an instruction from the control unit 16, indicator light 13 _1-12 corresponding to the pan 12 _{to 12} participating in the optimal combination is turned through the indication light drive circuit 18 The The control unit 16 outputs the processing result to the input / output device 14 as necessary. The control board 15 operates the combination weigher by the above method.
[Operation]
FIG. 3 is a flowchart schematically showing an example of a combination weighing method using the combination weigher according to the first embodiment of the present invention. Hereinafter, an outline of a weighing method using the combination weigher 10 of the present embodiment will be described with reference to FIGS. 1 and 3. In the following description, a case where the object to be weighed is a mixed salad will be described as an example.

  When the combination weigher is activated (start), parameters are first input (step S101). That is, when the operator operates the input / output device 14, a calorie conversion coefficient (for example, 0.2 kcal / g), a combined target calorie (target value of combined total calories: for example, 80 kcal), and a lower limit value of combined total calories. (For example, 0 kcal), the upper limit (for example, +2 kcal) of the combined total calories is set. The lower limit value and the upper limit value represent the lower limit value and the upper limit value of the allowable range by the difference from the target value (the same applies hereinafter). In the above-described example, the allowable range of the combined total calories is 80 kcal or more and 82 kcal or less. Note that the allowable range may not include a threshold value.

  When step S101 ends, the operator loads the mixed salad one by one on the empty weighing pan 12 (step S102).

  When step S102 ends, the control board 15 receives the detection result (measured value) of the weight of the mixed salad from each weighing pan 12, selects the one having the stable value among the received measured values, The calorie value is converted based on the calorie conversion coefficient (step S103).

  When step S103 ends, the control board 15 calculates a combined total calorie (total of caloric values obtained for the weighing dishes participating in the combination) for each combination of weighing dishes using the obtained calorie value ( Step S104). That is, when all the measured values are stable, the combined total calories are calculated for each of the combinations in which 1 to 12 pieces are extracted from the 12 weighing pans.

  When step S104 ends, the control board 15 determines whether there is a combination whose combined total calories are within the allowable range (step S105).

  If it is determined as YES in step S105, the control board 15 selects the combination whose total calories are closest to the target value among the combinations whose combined total calories are within the allowable range as the optimal combination (step S106).

  When step S106 is completed, the indicator lamp corresponding to the weighing pan participating in the optimum combination is turned on (step S107). The operator can produce a product whose total calories are substantially equal to the target value by collecting and packaging the mixed salad from the weighing pan corresponding to the indicator light that is lit. After step S107, the process returns to step S102. In practice, it is preferable that the placement of the object to be weighed (step S102), the combination calculation, and the display of the calculation result (steps S103 to S107) are simultaneously performed in parallel. With this operation, the operator can place and remove the object to be weighed at an arbitrary timing.

If NO is determined in step S105, an error is displayed on the input / output device 14 (step S108). If an error is displayed, the object to be weighed on the weighing pan is transferred by the operator (step S109), and the process returns to step S103.
[effect]
According to the combination weigher of this embodiment, a combination in which the combined total calories are approximately equal to the target value can be easily selected based on the measured value of the object to be weighed placed on each weighing pan. Therefore, products (substantially calorie food packs) that meet the diverse needs of consumers can be manufactured by a simple operation.
[Modification]
In the present embodiment, the condition (target calorie) to be satisfied by the combined total calorie is specified by three values: the combined target calorie, the upper limit value of the combined target calorie, and the lower limit value of the combined target calorie. However, the target calorie may be specified by one target value, or may be specified by two values of an upper limit and a lower limit. The target calorie may be set in any way as long as the conditions to be satisfied by the combined total calories can be specified. Hereinafter, the same applies to other parameters.

  In this embodiment, the input / output device 14 serves as both a calorie setting device for setting a target calorie and a calorie conversion coefficient setting device for setting a calorie conversion coefficient. May be independent devices. As described above, the input / output device 14 performs various functions, but each function is independent, and it is arbitrary which function is realized by the independently provided device (the same applies hereinafter).

  A connection port (transmission device) of a label printer (printing device: not shown) may be disposed on the side surface of the panel unit 20. Even if the I / O circuit is provided on the control board and connected to the I / O circuit and the connection port so that the printing data (weight, price, etc.) output from the control unit can be transferred to the label printer via the connection port. Good. In such a configuration, when a label printer is connected to the connection port, the control unit outputs the processing result to the connection port as necessary, so that the label printer can print calculation results (combined total calories, combined total weight, etc.). It becomes.

  A specific one or two of the weighing pans may be designated as a priority weighing pan (priority weighing unit) and may be forced to participate in the optimum combination. Such a configuration is convenient because a product including the object to be weighed is always obtained by placing the object to be processed on the priority weighing pan.

  In the above description, only the optimum combination selection (calorie combination weighing) is performed by calculation using calories converted from the measurement value. However, the optimum combination selection by calculation using weight (measurement value) is performed. (Weight combination weighing) and calorie combination weighing may be selectively executable. In such a case, the input / output device 14 executes a weight setting device for setting a target weight (for example, combination target weight, upper limit value of combination target weight, lower limit value of combination target weight), and calorie combination weighing. Or a combination condition selection device for selecting whether to perform weight combination weighing (combination condition). The combination condition is a method or condition for selecting an optimum one from a large number of combinations. For example, in calorie combination weighing, the weight value is converted into a calorie value using a calorie conversion coefficient, and the combination total calories close to the combination target calorie are selected. Therefore, it can be said that the combination condition is determined based on the calorie conversion coefficient and the target calorie. The input / output device 14 outputs a combination condition selection signal to the control board 15 based on the selection about the combination condition input by the operator. The control board 15 alternatively executes calorie combination weighing and weight combination weighing based on the received combination condition selection signal. According to such a configuration, the user can arbitrarily select and execute combination weighing based on calories or weight, which is convenient. The combination using the weight is substantially the same as that shown in FIG. 3 except that the measurement value can be used for the combination calculation as it is, and the description thereof will be omitted.

  Calorie combination weighing and selection of an optimal combination (price combination weighing) by calculation using a price (sales price or cost) converted from the weighing value may be selectively executable. In such a case, the input / output device 14 uses a price conversion coefficient setting device for setting a conversion coefficient (price conversion coefficient) between the measurement value and the price, a target price (for example, a combination target price, an upper limit value of the combination target price). , A lower limit value of the combination target price), and a combination condition selection apparatus for selecting whether to perform calorie combination weighing or price combination weighing (combination condition). The input / output device 14 outputs a combination condition selection signal to the control board 15 based on the selection about the combination condition input by the operator. The control board 15 alternatively executes calorie combination weighing and price combination weighing based on the received combination condition selection signal. According to such a configuration, the user can arbitrarily select and execute combination weighing based on calories or price, which is convenient. Note that the combination using the price is almost the same as that in FIG.

You may combine the selection using the cost converted from the measured value. In such a case, the input / output device 14 becomes a cost conversion coefficient setting device for setting a conversion coefficient (cost conversion coefficient) between the measurement value and the cost. The measurement value is converted into a cost, and a combined total cost is calculated for each combination. Of the combinations whose combined total calories are within the allowable range, the combination having the lowest combined total cost is selected as the optimal combination. According to such a configuration, it is possible to manufacture a product with the lowest cost while the combined total calories are within the allowable range.
(Second Embodiment)
The combination weigher and the combination weighing method of the second embodiment are for producing a set food in which the weighing pan is divided into a plurality of blocks and a plurality of types of objects to be weighed are combined to make the calorie substantially constant. Also, in order to prevent bias in each type of objects to be weighed in the set, the composition ratio of each type (the ratio of the total calories etc. of the weighing pans belonging to each block to the combined total calories etc.) satisfies the predetermined condition The combination is determined.
[Device configuration]
The apparatus configuration of the combination weigher of the second embodiment is the same as that of the first embodiment in terms of appearance and circuit configuration, and thus description thereof is omitted. In the combination weigher of this embodiment, four weighing pans are divided into a total of three blocks (groups), and different objects to be weighed are placed on each weighing pan. Hereinafter, the respective blocks are referred to as a block A, a block B, and a block C. The control device is configured to be able to store parameters separately for each block.
[Operation]
FIG. 4 is a flowchart schematically showing an example of a combination weighing method using the combination weigher according to the second embodiment of the present invention. Hereinafter, an outline of a weighing method using the combination weigher of the present embodiment will be described with reference to FIGS. 1 and 4. In the following description, a case where the objects to be weighed are lettuce, onion, and cone will be described as an example.

  When the combination weigher is activated (start), parameters are first input (step S201). That is, when the operator operates the input / output device 14, a combination target calorie (for example, 80 kcal), a lower limit value for the combined total calories (for example, 0 kcal), and an upper limit value for the combined total calories (for example, +2 kcal) Is set. For each of the three blocks, the calorie conversion factor (eg, 0.13 kcal / g for block A (lettuce), 0.35 kcal / g for block B (onion), and 0.11 kcal / g for block C (corn)). ) And a calorie composition ratio lower limit (for example, 60% for block A (lettuce), 10% for block B (onion), and 10% for block C (corn)). The lower limit value of the calorie composition ratio is an allowable range of the calorie composition ratio. That is, the input device 14 also serves as a calorie composition ratio setting device for setting an allowable range of the calorie composition ratio.

  When step S201 is completed, the operator loads the lettuce, onion, and cone one by one on the weighing pan 12 belonging to blocks A, B, and C, respectively (step S202).

  The control board 15 receives the detection result (measured value) of the weight of the object to be weighed (lettuce, onion, cone) from each weighing pan 12. Of the received metric values, those with stable values are selected. The selected measurement value is converted into a calorie value using the calorie conversion coefficient of the block to which the measurement value belongs (step S203).

  When step S203 ends, the control board 15 calculates the combined total calories and the calorie composition ratio of each block for each combination in which at least one weighing pan is taken out from each block (step S204). For example, for a certain combination, when the total combination kcal is 80.3 kcal and the total calories of the weighing pan belonging to block A (total calories of lettuce) is 50.4 kcal, the calorie composition ratio of block A for the combination is 62.8%.

  When step S204 is completed, the control board 15 excludes combinations in which the calorie composition ratio is lower than the lower limit value of the calorie composition ratio corresponding to each block in at least one block (step S205). For example, for a certain combination, when the composition ratio for block B is 9.5%, the composition ratio is below the lower limit (10%) of the calorie composition ratio of block B. Excluded.

  When step S205 is completed, the control board 15 determines whether there is a combination whose combined total calories are within the allowable range among the remaining combinations (step S206).

  If it is determined YES in step S206, the control board 15 selects the combination whose combined total calories are closest to the combination target calories from the remaining combinations as the optimal combination (step S207), and the weighing pan participating in the optimal combination The indicator lamp corresponding to is turned on (step S208). The operator collects the objects to be weighed from the weighing pan corresponding to the lit indicator light and wraps them to produce a product (a salad made of lettuce, onion and corn) whose total calories are approximately equal to the target value. Can do. After step S208, the process returns to step S202. In practice, it is preferable that the placement of the object to be weighed (step S202), the combination calculation, and the display of the calculation results (steps S203 to S208) are simultaneously performed in parallel. With this operation, the operator can place and remove the object to be weighed at an arbitrary timing.

If NO is determined in step S206, an error is displayed on the input / output device 14 (step S209). If an error is displayed, the object to be weighed on the weighing pan is transferred by the operator (step S210), and the process returns to step S203.
[effect]
According to the combination weigher of this embodiment, the same effects as those of the first embodiment can be obtained, and the following effects can be obtained.

  That is, according to the type of the object to be weighed, the calorie value is calculated from the measured value of the object to be weighed placed on each weighing pan, and a combination whose combined total calorie is approximately equal to the target value can be easily selected. Therefore, it is possible to produce products (substantially calorie set foods composed of a plurality of types of goods) that meet the diverse needs of consumers by simple operations.

Further, for each block, a combination in which the calorie composition ratio satisfies a predetermined condition is obtained. Therefore, a well-balanced set food can be easily manufactured.
[Modification]
Also in this embodiment, the same modification as the first embodiment is possible.

  Note that the selection based on the composition ratio is not essential and may be omitted. That is, it is not necessary to provide a condition for the composition ratio of the objects to be weighed in the respective blocks. Even with such a configuration, it is possible to manufacture products (a set food with substantially equal calories made up of a plurality of types of goods) that meet various consumer needs through simple operations.

  In the above description, the allowable range of the calorie composition ratio is set only by the lower limit value, but may be set by the lower limit value and the upper limit value. A target value may be set for the calorie composition ratio.

The number of blocks and the number of weighing pans belonging to each block may be settable by the user. For example, in step S201, the number of blocks and the position and number of weighing pans belonging to each block may be set.
(Third embodiment)
The combination weigher and the combination weighing method according to the third embodiment are for dividing a weighing pan into a plurality of blocks and combining a plurality of types of objects to be weighed to produce a set food in which calories and weight (or price) are substantially constant. Is. In addition, in order to prevent bias in each type of objects to be weighed during the set, the combination is determined so that a predetermined condition is satisfied for the component ratio of each type.
[Device configuration]
Since the apparatus configuration of the combination weigher of the third embodiment is the same as that of the second embodiment, description thereof is omitted. [Operation]
FIG. 5 is a flowchart schematically showing an example of a combination weighing method using the combination weigher according to the third embodiment of the present invention. Hereinafter, an outline of a weighing method using the combination weigher of this embodiment will be described with reference to FIGS. 1 and 5. In the following description, a case where the objects to be weighed are lettuce, onion, and cone will be described as an example.

  When the combination weigher is activated (start), parameters are first input (steps S301 to S302). Since step S301 is the same as step S201 of the second embodiment, a description thereof will be omitted. When step S301 is finished, the operator operates the input / output device 14, so that the combined target weight (target value of combined total weight, the same applies to the following, for example, 100 g), the lower limit value of combined total weight (for example, 0 g), An upper limit value (for example, +2 g) of the combined total weight is set (step S302). In such an example, the allowable range of the combined total weight is 100 g or more and 102 g or less. Note that the allowable range may not include a threshold value. When step S302 ends, the process proceeds to step S303, and then proceeds to step S304. Since step S303 is the same as step S202 of the second embodiment and step S304 is the same as step S203 of the second embodiment, the description thereof is omitted.

  When step S304 is completed, the control board 15 calculates a combined total calorie, a calorie composition ratio of each block, and a combined total weight (total of measured values) for each combination in which at least one weighing pan is extracted from each block ( Step S305).

  When step S305 ends, the process proceeds to step S306. Step S306 is the same as step S205 of the second embodiment, and a description thereof will be omitted.

  When step S306 ends, the control board 15 determines whether there is a combination whose combined total calories and combined total weight are within the corresponding allowable ranges among the remaining combinations (step S307).

  If it is determined as YES in step S307, the control board 15 leaves K (for example, K = 5) combinations in order from the combination with the combined total calories closest to the combination target calories among the remaining combinations, and the remaining is optimal. An indicator light that is excluded from the combination candidates (step S308) and that has the combined total weight closest to the combination target weight among the remaining combinations is selected as the optimal combination (step S309), and the indicator lamps corresponding to the weighing pans participating in the optimal combination Is turned on (step S310). The operator collects the objects to be weighed from the weighing pan corresponding to the lit indicator light and wraps them to produce a product (a salad made of lettuce, onion and corn) whose total calories are approximately equal to the target value. Can do. After step S310, the process returns to step S303. In practice, it is preferable that the placement of the objects to be weighed (step S303), the combination calculation, and the display of the calculation results (steps S304 to S310) are simultaneously performed in parallel. With this operation, the operator can place and remove the object to be weighed at an arbitrary timing.

If NO is determined in step S307, an error is displayed on the input / output device 14 (step S311). If an error is displayed, the object to be weighed on the weighing pan is transferred by the operator (step S312), and the process returns to step S304.
[effect]
According to the combination weigher of this embodiment, the same effects as those of the first embodiment and the second embodiment can be obtained, and the following effects can be obtained.

In other words, according to the type of object to be weighed, the calorie value is calculated from the measured value of the object to be weighed placed on each weighing pan, and a combination in which the combined total calorie and combined total weight are approximately equal to the target value is easily selected it can. Accordingly, it is possible to manufacture products (substantially equivalent calorie and substantially equal weight set foods composed of a plurality of types of goods) that meet the diverse needs of consumers by simple operations. In particular, since a combination in which both calories and weight are close to the target value is obtained, it is possible to manufacture a product that has a strong appeal to consumers.
[Modification]
Also in this embodiment, the same modification as the first embodiment and the second embodiment is possible.

  In the above description, the parameter (first variable) used for sorting together with calories is the weight, but the first variable may be a price. In any case, the input / output device 14 sets a first variable setting device for setting a target value of the first variable, and a first variable conversion coefficient that is a conversion coefficient between the measured value and the first variable. It also serves as the first variable conversion coefficient setting device. Even with a configuration in which the price is the first variable, it is possible to manufacture products (substantially equivalent calorie and approximately equal weight set foods composed of a plurality of types of goods) that meet various consumer needs through simple operations. In particular, since a combination of both calorie and price close to the target value can be obtained, a product with strong appeal to consumers can be manufactured.

  Along with calories, weight and price may be used for sorting. Even with such a configuration, it is possible to manufacture products (a set food having a substantially equal calorie and a substantially equal weight made of a plurality of types of articles) that meet various needs of consumers by a simple operation. In particular, since a combination in which all of the calories, price, and weight are close to the target value can be obtained, a product with even stronger appeal to consumers can be manufactured.

  It is not essential to divide the weighing pan into blocks. When there is only one type of object to be weighed, all weighing pans may be treated as homogeneous. Even with this configuration, it is possible to manufacture products (food packs of approximately equal calories and approximately equal weight) that meet the diverse needs of consumers by simple operations.

  The composition ratio does not necessarily have to be calculated based on calories. A component ratio (first variable component ratio) may be calculated based on a parameter (first variable) used for selection together with calories. In such a case, the input / output device 14 uses a first variable component ratio setting device (weight component ratio setting device, price component ratio) for setting an allowable range of the first variable component ratio (weight component ratio, price component ratio). Setting device).

  The allowable range of the calorie component ratio and the allowable range of the first variable component ratio (weight component ratio, price component ratio) are set only by the lower limit value, but may be set by the lower limit value and the upper limit value. A target value may be set for the calorie composition ratio.

  Furthermore, although it was the structure where only selection of the optimal combination by calculation using a calorie composition ratio (calorie composition ratio combination weighing) is performed, the first variable composition ratio which is a composition ratio based on the first variable (price or weight) It is possible to selectively execute the selection of the optimum combination (first variable component ratio combination metric) and the calorie component ratio combination metric by calculation using the. That is, the selection of the optimal combination (price component ratio combination metric) and the calorie component ratio combination metric by calculation using the price component ratio that is the component ratio based on the price may be selectively executable. It may be possible to selectively execute the calorie component ratio combination weighing and the selection of the optimum combination (weight component ratio combination weighing) by calculation using the weight component ratio which is the weight-based component ratio. Further, the calorie composition ratio combination weighing, the weight composition ratio combination weighing, and the price composition ratio combination weighing may be selectively executed. In such a case, the input / output device 14 becomes a configuration ratio selection device for selecting a configuration ratio to be used for computation. The input / output device 14 outputs a component ratio selection signal to the control board 15 based on selection of the component ratio used for the calculation input by the operator. Based on the received composition ratio selection signal, the control board 15 alternatively executes the calorie composition ratio combination weighing, the weight composition ratio combination weighing, and the price composition ratio combination weighing. This configuration is convenient because the user can arbitrarily select and execute combination weighing based on any of the calorie component ratio, the weight component ratio, and the price component ratio. Combination weighing may be performed using a plurality of constituent ratios together. The combination using the weight component ratio and the price component ratio is substantially the same as that in FIG.

In the above description, sorting is performed using a plurality of parameters sequentially, but sorting may be performed using a mixture. For example, the combination that minimizes the product of the difference between the combined total calorie and the combined target calorie and the difference between the combined total weight and the combined target weight may be selected as the optimal combination. The difference may be weighted for each parameter, and the combination that minimizes the product of the weighted differences may be selected as the optimum combination.
(Fourth embodiment)
[Device configuration]
Since the apparatus configuration of the combination weigher of the fourth embodiment is the same as that of the second embodiment, description thereof is omitted. [Operation]
FIG. 6 is a flowchart schematically showing an example of combination weighing using the combination weigher according to the fourth embodiment of the present invention. Hereinafter, an outline of a weighing method using the combination weigher of the present embodiment will be described with reference to FIGS. 1 and 6. In the following description, a case where the objects to be weighed are lettuce, onion, and cone will be described as an example.

  When the combination weigher is activated (start), parameters are first input (steps S401 to S404). Since step S401 is the same as step S301 of the third embodiment, a description thereof will be omitted. When step S401 is completed, the operator operates the input / output device 14, whereby a price conversion factor (for example, 2 yen / g for block A (lettuce) and 1 for block B (onion)) is set for each of the three blocks. 2 yen / g, 1 yen / g per block C (cone), combination target price (target value of combined total price: for example, 100 yen), and lower limit value of combined total price (for example, 0 yen) Then, an upper limit value (for example, +1 yen) of the combined total price is set (step S402). In the above example, the allowable range of the combined total price is 100 yen or more and 101 yen or less. Note that the allowable range may not include a threshold value. When step S402 ends, the process proceeds to step S403. Step S403 is the same as step 302 in the third embodiment, and a description thereof will be omitted. When step S403 is completed, the operator operates the input / output device 14 to calculate the cost conversion factor (for example, 1 yen / g for block A (lettuce), 0 for block B (onion)) for each of the three blocks. 0.5 yen / g and 0.6 yen / g per block C (cone) are set (step S404).

  When the input of the parameters is completed, the weighing object corresponding to each block is placed on the empty weighing pan by the operator (step S405), and the weighing value is stabilized by the control board 15. The measured value is converted into a calorie value (step S406), a price (step S407), and a cost (step S408).

  When step S408 ends, the combined total calories for each combination in which at least one weighing pan is taken out from each block using the obtained calorie value, weighing value, price, and cost by the control board 15; Combined total weight (sum of weighing values obtained for weighing pans participating in the combination), combined total price (sum of prices obtained for weighing pans participating in the combination), and combined total cost (weighing participating in the combination) The total cost obtained for the dish) and the calorie composition ratio of each block are calculated (step S409).

  When step S409 ends, the control board 15 excludes combinations whose calorie composition ratio is lower than the lower limit value in at least one block (step S410), and among the remaining combinations, the total combination It is determined whether or not there is a combination in which all of the calories, the combined total weight, and the combined total price are within the allowable range (step S411).

  When it is determined YES in step S411, the control board 15 leaves L (for example, L = 15) in the order in which the combined total calories of the remaining combinations are close to the combined target calories, and the others are excluded (step S412). In the remaining combinations, M (for example, M = 10) are left in the order in which the combined total weight is close to the combined target weight, and others are excluded (step S413), and the combined total price among the remaining combinations is set to the combined target price. Others are excluded except N (for example, N = 5) in the closest order (step S414), and the combination with the lowest combination total cost is selected as the optimal combination (step S415). When step S415 is completed, the control board 15 turns on the indicator lamp corresponding to the weighing pan participating in the optimum combination (step S416). The operator collects the objects to be weighed from the weighing pan corresponding to the indicator lamps that are lit, and wraps them so that the total calories, total weight, and total price are approximately equal to the target value and low in cost (lettuce and onion). And corn salad). After step S416, the process returns to step S405. In practice, it is preferable that the placement of the object to be weighed (step S405), the combination calculation, and the display of the calculation results (steps S406 to S416) are simultaneously performed in parallel. With this operation, the operator can place and remove the object to be weighed at an arbitrary timing.

If NO is determined in step S411, an error is displayed on the input / output device 14 (step S417). If an error is displayed, the object to be weighed on the weighing pan is replaced by the operator (step S418), and the process returns to step S406.

  That is, according to the type of object to be weighed, the calorie value, price, and cost are calculated from the measured value of the object to be weighed placed on each weighing pan, and the combined total calorie, combined total price, and combined weight are abbreviated as target values. Equal and low cost combinations can be easily selected. Accordingly, it is possible to produce products (set foods having substantially equal calories, substantially equal weights, and substantially equal prices made up of a plurality of types of goods) at low cost that meet various consumer needs through simple operations.

Further, for each block, a combination in which the calorie composition ratio satisfies a predetermined condition is obtained. Therefore, a well-balanced set food can be easily manufactured.
[Modification]
Also in this embodiment, the same modification as the first to third embodiments is possible. That is, it is arbitrary whether the combination calculation is performed based on the calorie value, the weight, or the price, or the combination calculation is used in parallel. Further, it may be possible to select any one of calorie combination weighing, weight combination weighing, and price combination weighing. Whether or not to incorporate the cost and component ratio into the combination condition is also arbitrary. It is arbitrary whether the component ratio is calculated by calorie, weight, or price, and a combination condition may be determined using a plurality of types of component ratios.
