In the following description, the same or corresponding elements are denoted by the same reference symbols throughout all the drawings, and redundant description thereof is omitted. Further, the present invention is not limited to the following embodiment.

(Embodiment)
Fig.1 (a) is a perspective view which shows the external appearance of the product production support apparatus of the example of 1 structure of embodiment of this invention, FIG.1 (b)-(e) is a display part of the product production support apparatus. It is a figure which shows the example of a display of a screen. FIG. 2 is a functional block diagram showing an outline of the product production support apparatus.

  The product production support device of this configuration example is a weighing device that is used to subdivide a purchase product composed of a plurality of objects to be weighed into a plurality of products of the same price (that is, produce the product). This product production support device (weighing device) is provided on a weighing pan 1 on which an object to be weighed is placed, a main body 6 incorporating a weight sensor 2 and a control unit 7 shown in FIG. An operation input unit 3, a display unit 4, a determination lamp 5, and the like are provided. The weighing pan 1 is supported by a weight sensor 2 composed of a load cell or the like fixed inside the main body 6. The weight sensor 2 measures the weight of the object to be weighed placed on the weighing pan 1. A weighing unit 10 is configured by the weighing pan 1 and the weight sensor 2.

  The operation input unit 3 is used to input the operation of the product production support apparatus and parameter values, and functions as a first information setting unit, a second information setting unit, and the like.

  The display unit 4 is configured using, for example, a small liquid crystal display, can display a weight measurement value or the like on a screen, and functions as a notification unit that notifies various information calculated by the control unit 7. The determination lamp 5 is configured using, for example, a multicolor LED, and can change the emission color.

  The control unit 7 is composed of, for example, a microcontroller, and includes a calculation control unit 8 including a CPU of the microcontroller and a storage unit 9 including a RAM and a ROM of the microcontroller. The control unit 7 controls the entire product production support apparatus by the CPU of the arithmetic control unit 8 executing the CPU execution program stored in the ROM of the storage unit 9. For example, the control unit 7 inputs a measurement value from the weight sensor 2. In addition, a signal from the operation input unit 3 is input, and a signal such as data to be displayed on the display unit 3 is output. Further, the determination lamp 5 is controlled. In addition, the control unit 7 also functions as a calculation unit, an actual production number counting unit, and the like. The control unit 7 may be configured by a single control device that performs centralized control, or may be configured by a plurality of control devices that perform distributed control in cooperation with each other.

  An outline of an example of the operation of the product production support apparatus configured as described above will be described. 3 and 4 are flowcharts showing an outline of an example of the operation of the product production support apparatus, and shows an example of the product production support method of the present invention. The operation of the product production support apparatus is controlled by the control unit 7, and all the information necessary for operating the product production support apparatus is stored in the storage unit 9 and stored during operation. All the information to be stored is stored in the storage unit 9.

  This product production support device is used, for example, when a retailer purchases a box-by-box purchase of items to be weighed made of the same kind of vegetables such as cucumbers and potatoes. It is used to divide products (raw materials) into a plurality of products with the same selling unit price.

  A person such as an administrator or an operator, after turning on the product production support device, operates the operation input unit 3 so that a predetermined parameter value can be set (input), and the parameter value is input. can do. When a parameter value is input (step S1), the control unit 7 stores the input parameter value (step S2). Here, the profit rate, the sales unit price of the product, and the entry are set as parameters. These set parameters are displayed on the screen of the display unit 4 as shown in FIG. Here, the “fill” is a value indicating the size (width) of the allowable weight range of the product, that is, the difference between the upper limit value and the lower limit value of the allowable weight range of the product. Here, the allowable weight range of a product is an allowable range of the weight of one product, and the product is, for example, a product sold as one pack.

  For example, the profit rate is determined to a desired value for each product, the sales unit price of the product is determined to be the best selling price, and the slot is determined based on experience and the like. And these values are not changed frequently. Therefore, in this example, the values of the three parameters of the profit rate, the sales unit price of the product, and the fitting are not frequently changed, and these values are stored in the storage unit 9 even when the power is turned off. Has been. Therefore, when no parameter value is input and step S2 is not performed, the most recently stored parameter value is used in subsequent processing (steps S6 and S7).

  Further, the operation input unit 3 is operated so that a purchase price value can be set (input), and the purchase price value can be input. When the purchase price value is input (step S3), the control unit 7 stores the input purchase price value (step S4). The input purchase price is displayed on the screen of the display unit 4 as shown in FIG.

  Next, when a purchase item (raw material for one box) is placed on the weighing pan 1 by a person such as an administrator or an operator, the weight of the purchase item is measured and the weight is stored (step S5). . At this time, the measured weight is stored as “raw material remaining weight value (Ws)”.

  Subsequently, the control unit 7 calculates and stores the production number (scheduled production number) of products necessary for obtaining the set profit rate (step S6), and further produces the planned production number. The upper limit value and the lower limit value of the allowable weight range of the commodity as a condition are calculated and stored (step S7), and the calculated planned production number and the upper limit value and lower limit value of the allowable weight range are displayed on the display unit 4 (step S7). S8). For example, as shown in FIG. 1 (d), the planned number of production (24 packs), the lower limit value (397g) and the upper limit value (417g) of the allowable weight range are displayed on the screen of the display unit 4.

  Here, a specific calculation method of the planned production number, the lower limit value and the upper limit value of the allowable weight range in steps S6 and S7 will be described.

  The profit ratio (ratio of profit to purchase price) is α (%), the sales unit price of the product is b (yen), the entry is x (g), and the purchase price of one box is C (yen). It is assumed that the measured weight of the raw material contained in one box (the weight of the purchased product measured in step S5) is WA (g). And when the minimum production number required to achieve the profit rate α is the planned production number N (pieces), the upper limit value of the allowable weight range of the product is WH (g), and the lower limit value is WL (g) In addition, the relationship represented by the following equations (1) to (3) is satisfied.

b · N ≧ C (1 + α / 100) (1)
WH · N ≦ WA (2)
WH-WL = x (3)
N is the smallest integer value that satisfies the expression (1).

  Here, when step S5 is completed, since the profit rate α, the sales unit price b of the product, the slot x, the purchase price C of the box, and the weight WA of the purchase are known, the above (1 ) To (3), the planned production number N, the upper limit value WH and the lower limit value WL of the allowable weight range of the product are calculated by the following formulas, for example (steps S6 and S7).

N = C (1 + α / 100) / b
WH = WA / N
WL = WH-x
For example, the profit rate α = 20 (%), the product sales unit price b = 300 (yen), the entry x = 20 (g), and the purchase price of one box C = 6000 (yen) enters the same box. If the weight of the raw material is WA = 10000 (g),
N = 6000 (1 + 20/100) / 300 = 24 (pieces).
When the calculated value of N has a fractional number, it is preferable to round up to an integer value in order to secure the profit rate α. Also,
WH = 10000 / 24≈417 (g)
WL = 417-20 = 397 (g).

  As described above, the planned production number N, the lower limit value WL and the upper limit value WH of the allowable weight range are calculated and displayed on the display unit 4 (step S8).

  Next, in order to divide the raw material for one box into a plurality of commodities, the worker first performs a work start operation on the operation input unit 3 to input a work start signal to the control unit 7. (Step S9).

  When producing this product, the operator takes out the raw material that will be one product from the purchased product placed on the weighing pan 1 and places it in a container (not shown) such as a tray. This is repeated, and the raw materials put in each container become a product.

  Here, the control unit 7 obtains a measurement value (a weight value of the raw material on the weighing pan 1) from the weight sensor 2 at predetermined time intervals. For example, as shown in FIG. The acquired measured value (6800 g) is displayed on the screen of the display unit 4.

  When the raw material is taken out from the weighing pan 1 and the measurement value acquired from the weight sensor 2 is changed (step S10), the control unit 7 stores the measured raw material weight at that time. By subtracting from the value Ws, a reduction amount of the raw material (that is, the weight of the raw material taken out from the weighing pan 1) is calculated (step S11). Then, if the decrease amount is within the allowable weight range, it is determined to be an appropriate amount, and if it is smaller than the lower limit value WL of the allowable weight range, it is determined that it is light, and if it is larger than the upper limit value WH, it is determined to be an excessive amount (step S12).

  If it is determined that the weight is light, the determination lamp 5 is lit red (step S14), and if it is determined that the amount is excessive, the lamp is lit yellow (step S15), and the process returns to step S10. If it is determined that the amount is appropriate, the determination lamp 5 is lit in blue (step S13).

  Here, when the operator takes out the raw material from the weighing pan 1 and the determination lamp 5 is lit in red, the operator further takes out the raw material and puts it in the container so that the determination lamp 5 is lit in blue. Adjust the amount of raw materials. When the determination lamp 5 is lit yellow, a part of the raw material put in the container is returned to the weighing pan 1 to adjust the amount of the raw material put in the container so that the determination lamp 5 lights in blue. And when the judgment lamp 5 lights in blue, the raw material put into the container is made into one goods. In this way, the worker sequentially produces products.

  The control unit 7 proceeds to step S21 after step S13, and stores (updates) the measured value of the weight sensor 2 at that time as the raw material remaining weight value Ws (step S21). Further, the reduction amount of the raw material when determined to be an appropriate amount is stored as a product weight value (step S22). The product weight value is sequentially stored every time step S22 is performed. Then, the actual production number of the product (actual production number up to the present time) is stored (updated) (step S23), and the average weight of the product produced so far is calculated (step S24). For example, FIG. As shown in FIG. 4, the actual number of products (8 packs) and the average weight (400 g) are displayed on the screen of the display unit 4 (step S25).

  Regarding the actual production number of the product in the above-described step S23, for example, the initial value of the actual production number k before the start of work is set to 0, and the value of the actual production number k is increased by 1 in step S23. That's fine. Moreover, what is necessary is just to calculate the average value of the goods weight value memorize | stored by step S22 so far about the average weight of goods in step S24.

  Next, the control unit 7 compares the actual production number k with the planned production number N (step S26). If the actual production number k is smaller than the planned production number N, the control unit 7 returns to step S10.

  When the actual production number k becomes equal to the planned production number N, it is notified that the planned production number N has been produced (step S27). This notification is performed by, for example, displaying “scheduled number end” in the predetermined area 4p (FIG. 1E) of the display unit 4.

  Further, the control unit 7 determines whether or not the raw material remaining weight value Ws updated in step S21 is equal to or greater than the lower limit value WL of the allowable weight range (step S28), and the raw material remaining weight value Ws is the lower limit value WL. If it is less than this, the operator is notified that the production work has been completed (step S31). This notification is performed, for example, by displaying “end of production” in a predetermined area 4 p of the screen of the display unit 4.

  In step S28, if the remaining raw material weight value Ws is equal to or greater than the lower limit value WL of the allowable weight range, it is notified that the product can be continuously produced (step S29). This notification is performed, for example, by displaying “Production can be continued” in a predetermined area 4 p of the screen of the display unit 4.

  In this case, when the operator operates the operation input unit 3 to perform the production continuation instruction operation, the process returns to step S10, and when the production end instruction operation is performed, the process proceeds to step S31 (step S30).

In step S26, if the actual production number k is larger than the planned production number N, it is determined whether the raw material remaining weight value Ws updated in step S21 is equal to or greater than the lower limit value WL of the allowable weight range. (Step S32) If the raw material remaining weight value Ws is less than the lower limit WL, the profit rate (α _k ) corresponding to the actual production number k is calculated (Step S35). Here, the profit rate α _k is calculated by the following equation using the actual production number k, the product sales unit price b, and the purchase price C of one box.

α _k = (b · k / C−1) × 100
Next, in step S36, the actual production number k and the profit rate α _k are notified of the completion of the production work. This notification is performed, for example, by displaying content to be notified on the screen of the display unit 4.

  In step S32, if the raw material remaining weight value Ws is equal to or greater than the lower limit value of the allowable weight range, it is notified that the product can be continuously produced (step S33). This notification is performed, for example, by displaying “Production can be continued” on the screen of the display unit 4.

  In this case, when the operator operates the operation input unit 3 to perform a production continuation instruction operation, the process returns to step S10, and when a production end instruction operation is performed, the process proceeds to step S35 (step S34).

  Also in step S31, the profit rate α and the actual production number k (= scheduled production number N) set at the beginning may be displayed on the screen of the display unit 4.

  In addition, a speaker or the like may be provided in the product production support device, and in steps S27, S29, S31, S33, and S36, the content (notification content) to be displayed on the screen of the display unit 4 may be notified by voice from the speaker. .

  In steps S28 and S32, when the raw material remaining weight value Ws is equal to or larger than the lower limit value WL of the allowable weight range, an estimated value (estimated number) n of products that can be produced using the raw material of the remaining weight value Ws is calculated. You may make it alert | report. In this case, the estimated number n may be displayed on the display unit 4 or may be notified by voice from the speaker described above. Here, the estimated number n may be calculated as, for example, an integer value obtained by calculating a value of Ws / WL and truncating the value after the decimal point. The estimated number n is a guide only, and it is not always possible to produce n products.

  At the end of production, for example, after steps S31 and S36, the control unit 7 determines the weight of the purchased item (raw material), the purchased item purchase price, the sale unit price of the item, the actual production number, and the planned total sales amount ( = Sales unit price × actual production number) and profit rate may be generated in association with the production date and stored in the storage unit 9. In this case, a clock such as a real-time clock is provided, and the control unit 7 acquires the date of the day from the clock and sets it as the production date. If the production date is designated (input) by operating the operation input unit 3, the control unit 7 is configured to read the production information of the designated production date from the storage unit 9 and display it on the display unit 4. It may be. The control unit 7 may store the production information in a removable medium (not shown). In this case, the removable medium storing the production information can be set in an information processing apparatus such as a personal computer to view the production information.

  In addition, when measuring the weight of the purchased product in step S5, for example, the raw material is taken out from the purchased box and placed on the weighing pan 1, and the weight is measured. It is also possible to remove raw materials that are not commercial products (that is, raw materials that should not be included in the commercial products) and place only raw materials that are in good condition on the weighing pan 1 for weighing. At this time, a predetermined container (tare) may be placed on the weighing pan 1, and the raw material may be put into the container to measure the weight. In this case, the control unit 7 uses the tare function. A value obtained by subtracting the weight of a predetermined container from the measured value is calculated as the weight of the purchased product.

  In the above description, the case where one box of raw materials to be commodities is purchased has been described. However, when a plurality of boxes of the same raw materials are purchased, for example, after the first box is manufactured as described above, 2 In the case of the j-th box after the box (j is an integer of 2 or more), the same processing as that after step S10 after the work starts is performed using the same lower and upper limit values of the allowable weight range as the first box. You may do it. In this case, for example, at the end of product production using the raw material of the (j-1) box, by placing the raw material of the j box on the weighing pan 1 and performing a “continue production” operation at the operation input unit 3 The control unit 7 may update the scheduled production number N used in step S26 to a value of, for example, j × N, and perform the same process as in step S10 and subsequent steps.

  As another method when purchasing the same raw material in multiple boxes, in step S4, the total purchase price of the purchased raw material is input as the purchase price, and in step S5, the total weight of the purchased raw material is measured. However, it may be the weight WA of the purchased item. In this case, in step S5, for example, the weights of the raw materials for each box may be measured and added to obtain the purchased product weight WA. Here, the control unit 7 has a function of adding the measured weight.

  In the above, when producing products by subdividing the purchased items, the operator sequentially takes out the raw materials that will be one item of merchandise from the purchased items placed on the weighing pan 1. However, the commodity may be produced by placing the raw material to be a commodity on the empty weighing pan 1. In this case, the control unit 7 determines that the weight of the raw material on the weighing pan 1 is an appropriate amount if it is within the allowable weight range, determines that the weight is light when the weight is smaller than the lower limit value WL of the allowable weight range, and is larger than the upper limit value WH. And configured to determine overdose.

  In the present embodiment, the desired profit rate α, the sales unit price b, the slot x and the purchase price C are set, and the weight WA of the purchased product is measured, thereby realizing the desired profit rate α. Since the upper limit value WH and the lower limit value WL of the allowable weight range of the product are automatically calculated, it is possible to save time and labor for a person such as an administrator to reduce the burden on the person. Moreover, since the upper limit value WH and the lower limit value WL of the allowable weight range of the product calculated by the control unit 7 are automatically set (stored in the storage unit 9), these are operated by operating the operation input unit 3. This saves the human effort.

  In general, the profit rate α, the sales unit price b, and the slot x are not frequently changed, and these values are stored in, for example, a non-volatile memory area (storage means of the present invention) in the storage unit 9. Thus, it is possible to save time and labor for the human to set each time by operating the operation input unit 3.

  In the present embodiment, the upper limit of the allowable weight range of the product for achieving the desired profit rate α when the desired production rate α and the desired product sales unit price b are set by the product production support apparatus. Although the case where it has the function (1st function) which calculates the value WH and the lower limit WL was demonstrated, you may have the following 2nd-3rd functions further.
