Description

  The present invention relates to a method for indicating an indication of a cutting position and an apparatus therefor in order to cut a single lump of an article such as food to obtain a predetermined weight section.

  Conventionally, foods such as fish, meat, and vegetables may be packaged and sold in a state of being cut into a size or weight that is easy to use, such as a single piece. At this time, it is preferable for the convenience of handling, such as unifying the selling price per pack, that the plurality of slices cut out from a single lump are substantially aligned with a constant weight such as 100 g. For example, in the case of an article having a constant cross-section along its length and a constant weight distribution along its length, such as a food ham, one chunk of the article is of equal thickness. It is easy to cut out sections of equal weight many times by rounding them. However, many articles have a non-uniform weight distribution over their entire length. In such a case, in order to cut a section of a predetermined weight from one lump of an article once or a plurality of times, when a person performs a cutting operation of the article with intuition, except for a case of a considerable skill There was a problem in that the weight of the sections varied.

  Therefore, Patent Document 1 proposes a split scale that displays a split ratio when only a desired weight or a desired amount is cut out from a lump of objects to be weighed. This divided scale is divided into a weighing unit for weighing the object to be weighed, an input unit for inputting the weight or amount to be divided, and a divided weight value or divided amount input from this input unit as a dividend. A calculation unit that calculates the rate and a display unit that displays the obtained division ratio are provided.

  Patent Document 2 discloses an automatic weighing and cutting device that processes fish as a constant-weight fillet. This automatic weighing and cutting device preliminarily accumulates fish weight data for each fish species, stores in advance the average value of the cutter movement amount and the tilt angle of the cutter for making a fillet with respect to the average weight of the fish body, When the fish to be transported is measured, its weight is measured, compared with the stored average weight, and the stored average moving amount and inclination angle of the cutter are read out to correspond to the weight of the fish to be processed. The movement amount and tilt angle of the cutter are calculated and output to the cutter.

Yes. A calculation signal from the electronic balance 30 and an input signal from the input unit 25 of the operation indicator 24 are input to the arithmetic control unit 20 via an input port. Further, the calculation control unit 20 outputs a measurement request signal to the electronic balance 30 and a display image signal to the display unit 26 of the operation display 24 via an output port.

  The ROM 22 stores a program and data necessary for the cutting position instruction apparatus 10 to execute at least the cutting position instruction processing described in the present embodiment. The RAM 23 stores a plurality of article models, and these article models are appropriately read out by the CPU 21 during the processing performed by the cutting position indicating device 10 and used for calculations and the like.

Let

(Flow of cutting position instruction processing)
Next, the flow of the cutting position instruction process performed by the cutting position instruction device 10 will be described with reference to FIG. FIG. 2 is a flowchart showing the flow of the cutting position instruction process.

  First, an operator who wants to cut a section of a predetermined weight from a lump of articles leaves the article on the weighing pan of the electronic balance 30 and sends a weighing command to the arithmetic control unit 20 via the operation display 24. input. The arithmetic control unit 20 receives a weighing command (step S1), outputs a weighing request to the electronic balance 30 (step S2), and obtains a weighing signal of the total weight of the article from the electronic balance 30 (step S3). In addition, by providing the electronic scale 30 in the cutting position indicating device 10, the total weight of the article can be accurately and easily input to the calculation control unit 20. However, the total weight of the article is obtained via the operation indicator 24. It can also be configured to be input to the arithmetic control unit 20.

  Subsequently, the operator operates the operation display 24 to select one article model corresponding to the article from among a plurality of article models stored in the RAM 23 of the arithmetic control unit 20. The article model selection information is input from the input unit 25 of the operation display 24 to the arithmetic control unit 20 (step S4). The arithmetic control unit 20 reads out one article model to be used from among a plurality of article models stored in the RAM 23 based on the received model selection information (step S5).

  Subsequently, the operator operates the operation indicator 24 to select one calculation mode from among a plurality of calculation modes registered to be usable, and further operates the cutting position display button to select these calculation modes. The calculation mode selection information and the cutting position display command are input to the calculation control unit 20 (steps S6 and S7). The calculation control unit 20 that has acquired the calculation mode selection information and the cutting position display command first determines the weight value (cutout weight value M) of the section cut out from the lump of articles according to the selected calculation mode (step S1). S8).

  Here, as the “calculation mode”, a first mode for obtaining a cutting position instruction for cutting out a target weight section, a second mode for obtaining a cutting position instruction for cutting out a target price section, and a target calorie section are cut out. A third mode for obtaining an instruction for a cutting position for cutting, a fourth mode for obtaining an instruction for a cutting position for cutting out a segment of a target number of divisions, and a section close to a target weight of a number capable of equally dividing a lump of articles without waste A plurality of calculation methods in the fifth mode for obtaining an instruction of a cutting position for cutting out are prepared for determining the cutting weight value M.

  When the first mode is selected, the arithmetic control unit 20 requests input of a weight value that is a cutting target, and determines the input weight value as the cut weight value M. When the second mode is selected, the arithmetic control unit 20 requests input of a target price and a unit price (price per unit weight) as a cutting target, and the target price is calculated from the input target price and unit price. Is calculated, and the calculated weight is determined as the cut weight value M. When the third mode is selected, the calculation control unit 20 requests input of a target calorie to be a cutting target, and based on the input target calorie and information on calorie consumption per unit weight included in the article model The weight corresponding to the target calorie is calculated, and the calculated weight is determined as the cut weight value M. When the fourth mode is selected, the calculation control unit 20 requests the input of the target number of divisions to be a cutting target, and from the input target number of divisions and the total weight of the articles acquired from the electronic balance 30, The weight when the article is equally divided into the target number of divisions is calculated, and the calculated weight is determined as the cut weight value M. When the fifth mode is selected, the calculation control unit 20 requests input of a target weight that is a cutting target, and the target weight is calculated from the input target weight and the total weight of the articles obtained from the electronic balance 30. Calculate the optimal number of divisions that can divide the article into parts with a nearer weight without waste, further calculate the weight when the article is equally divided into the optimal number of divisions, and determine the calculated weight as the cut weight value M To do.

  When the cutout weight value M is determined by performing the calculation according to the calculation mode as described above, the calculation control unit 20 cuts a lump of articles in a direction substantially orthogonal to the full length direction to cut out the cut weight value. Information relating to the position of the cutting line Z for cutting out the M section, that is, cutting position information is created (step S9). FIG. 3 is a flowchart showing a flow of creating cutting position information.

  As shown in FIG. 3, when creating the cutting position information, the arithmetic control unit 20 first determines the position of the cutting line Z corresponding to the cutting weight value M (step S21). The cutting line Z is a line segment in a direction substantially orthogonal to the full length direction of the article (within a range of + -10 degrees from the direction perpendicular to the full length direction of the article). It becomes a cutting line when cutting out the section of the cutting weight value M from the article. The arithmetic control unit 20 calculates the position of the cutting line Z using the article model so that the weight from the left end (one end) of the article to the cutting line Z becomes the cut weight value M (step S21). The position of the cutting line Z at this time is expressed as a ratio Dz of the length from the left end of the article to the cutting line Z with respect to the total length of the article.

Next, the arithmetic control unit 20 determines the division number N (step S22). At this time, the arithmetic control unit 20 first calculates the smallest real number n such that the ratio Dz is smaller than 1/2 ⁿ (one of the nth power of 2), and is calculated by subtracting 1 from the real number n. A number that is a power of 2 is defined as a division number N. A scale line is set at the boundary position of each divided piece when the entire length of the article is equally divided by the number of scale divisions N and at both ends of the article. Here, the “scale line” is a scale virtually attached to the article, and an operator who wants to cut the article can easily determine the position of the cutting line Z by using the scale line. Can do. If the number of scale lines is excessively large, the position error becomes large and the operator's feeling is confused. Therefore, it is desirable that the number N of scale divisions does not exceed 16.

  Subsequently, the arithmetic control unit 20 sets the length between adjacent scale lines as one scale, and sets the scale line adjacent to one of the cutting lines Z (here, the left side) as a “reference scale line”, as a reference for one scale. A ratio D of the length from the scale line to the cutting line Z is calculated (step S23). Here, the reference scale line is the leftmost scale line, that is, the left end of the article.

  The arithmetic control unit 20 then calculates the division number N, the ratio Dz of the length from the left end of the article to the cutting line Z with respect to the total length of the article, the reference scale line, and the reference scale line to the cutting line Z for one scale. Cutting position information including at least the length ratio D is created (step S24).

  Then, when the cutting position information is created as described above, returning to FIG. 2, the arithmetic control unit 20 creates cutting position instruction information including at least the cutting position information and outputs it to the display unit 26 of the operation display 24. (Step S10), and the cutting position instruction process ends. The cutting position instruction information is preferably image information including the cutting position information and the two-dimensional outer shape and the cut weight value M included in the article model.

  In the operation display 24 that has received the output of the cutting position instruction information, at least the scale division number N or the scale line, the cutting line Z, the reference scale line, and the length from the reference scale line to the cutting line Z for one scale. Is displayed on the display unit 26 as an image, a numerical value, or an image and a numerical value. The operator looks at the information displayed on the display unit 26, and first, virtually arranges each scale line that equally divides the entire length of the article into the number of scale divisions N, and is adjacent to the reference scale line and the right side thereof. The position of the scale line to be registered is determined, the position of the cutting line Z is determined at a position where the length from the reference scale line is a ratio D to one scale, and the article is cut by this cutting line Z. As a result, the operator can cut out a section having an approximate cut-out weight value M from a batch of articles without measuring the length of the article or section with a ruler or the like.

  As described above, in the cutting position indicating device 10, the scale line that serves as a guide for the cutting position is a position that is 1/2, 1/4, 1/8, or 1/16 of the total length of the article. Compared with the case where the number of scale lines is set to the number of scale divisions N (for example, 3, 5, etc.), it is easier for humans to visually determine the position of the scale lines. In addition to this, the cutting position (cutting line Z) of the article is displayed as a ratio D of length to one scale which is shorter than the full length of the article, so that the operator can more accurately and easily understand the cutting position guideline. Can be directed to. Therefore, the operator cuts the article at the cutting position (cutting line Z) instructed by the cutting position indicating device 10 based on the sense, so that a section having a weight close to the cut weight value M can be obtained with higher accuracy. It can be expected to be cut out.

  In the cutting position indicating device 10 described above, processing is performed assuming that a lump of articles is cut from the left end portion and a section having a cut weight value M is cut out. Processing can also be set to disconnect.

(Application example 1)
Below, while applying the flow from the generation of the cutting position information (step S9) to the output of the cutting position instruction information (step S10) in the cutting position instruction processing described above, application example 1 using specific numerical values is applied. explain. FIG. 4 is a diagram illustrating Application Example 1, and FIG. 5 is a diagram of a cutting position instruction screen according to Application Example 1.

  As shown in FIG. 4, in Application Example 1, a piece having a cut weight value M of 100 g is cut out from a lump of carrot of 500 g. First, the calculation control unit 20 refers to the information included in the carrot article model, and calculates the position of the cutting line Z for obtaining a 100 g section from a lump of 500 g carrot (step S21). The ratio Dz of the length from the left end of the article to the cutting line Z with respect to the total length of the article thus calculated was 21/100 (21%).

  Next, the arithmetic control unit 20 determines the division number N (step S22). The scale division number N derived from the ratio Dz (= 21/100) is 4. Subsequently, the arithmetic control unit 20 calculates the ratio D of the length from the reference scale line to the cutting line Z by using the left end of the article as the reference scale line (step S23). The ratio D of the length from the reference scale line to the cutting line Z thus calculated was 85/100 (85%). Further, the arithmetic control unit 20 has a scale division number N (= 4), a ratio Dz (= 21/100) of the length from the left end of the article to the cutting line Z with respect to the total length of the article, a reference scale line, 1 Cutting position information including at least a ratio D (= 85/100) of the length from the reference scale line to the cutting line Z with respect to the length of the scale is created (step S24).

  Then, the calculation control unit 20 creates cutting position instruction information including at least cutting position information, and outputs the cutting position instruction information to the display unit 26 of the operation display 24 (step S10). Then, for example, a cutting position instruction screen as shown in FIG. 5 is displayed on the display unit 26 of the operation display 24. On the cutting position instruction screen shown in FIG. 5, the two-dimensional shape of the article based on the article model, the scale line as a guide for cutting, the reference scale line, and the cutting line Z are displayed as images, and the division number N and 1 A ratio D of the length from the reference scale line to the cutting line Z with respect to the scale length is displayed as a numerical value. In the cutting position instruction screen shown in FIG. 4, the ratio D is displayed as a percentage, but may be displayed by other expression methods such as fraction display. The reference scale lines are preferably displayed in different colors so that they can be easily distinguished from other scale lines.

  Then, the worker who performs the cutting work visually recognizes the information displayed on the cutting position instruction screen, first, virtually arranges a graduation line that equally divides the entire length of the article into four parts, and sets the left end of the article. The reference scale line is used, and the cutting line Z is registered at a position where the ratio of the length of the reference scale line to the one scale immediately to the right is 85%, and the article is cut by the cutting line Z. This allows the operator to cut out approximately 100 g of slices from a 500 g lump of carrot.

(Application example 2)
Hereinafter, the flow from the creation of the cutting position information (step S9) to the output of the cutting position instruction information (step S10) in the cutting position instruction processing of the cutting position instruction apparatus 10 is applied using specific numerical values. This will be explained with reference to 2. FIG. 6 is a diagram for explaining Application Example 2, FIG. 7 is a diagram of a cutting position instruction screen according to Application Example 2, and FIG. 8 is a diagram of a modification of the cutting position instruction screen according to Application Example 2.

  As shown in FIG. 6, in Application Example 2, it is assumed that a slice having a cut weight value M of 145 g is cut out from a lump of fish of 500 g. First, the calculation control unit 20 refers to information included in the fish article model, and calculates the position of the cutting line Z for obtaining a 145 g section from a lump of 500 g fish (step S21). Note that the article model information is configured such that discarded parts such as fish heads and tails are excluded from the cutout weight value M. The ratio Dz of the length from the left end of the article to the cutting line Z with respect to the total length of the article thus calculated was 36/100 (36%).

  Next, the arithmetic control unit 20 determines the division number N (step S22). The scale division number N derived from the ratio Dz (= 36/100) is 2. Subsequently, the arithmetic control unit 20 calculates the ratio D of the length from the reference scale line to the cutting line Z with respect to one scale using the left end of the article as the reference scale line (step S23). Thus, the ratio D of the length from the reference scale line to the cutting line Z with respect to one scale was 72/100 (72%). Further, the arithmetic control unit 20 has a division number N (= 2), a ratio Dz (= 36/100) of the length from the left end of the article to the cutting line Z with respect to the total length of the article, a reference scale line, 1 Cutting position information including at least the ratio D (= 72/100) of the length from the reference scale line to the cutting line Z with respect to the length of the scale is created (step S24).

  Then, the calculation control unit 20 creates cutting position instruction information including at least cutting position information, and outputs the cutting position instruction information to the display unit 26 of the operation display 24 (step S10). Then, for example, a cutting position instruction screen as shown in FIG. 7 is displayed on the display unit 26 of the operation display 24. On the cutting position instruction screen shown in FIG. 7, the two-dimensional shape of the article based on the article model, the scale line as a guide for cutting, the reference scale line, and the cutting line Z are displayed as images, and the division number N and 1 A ratio D of the length from the reference scale line to the cutting line Z with respect to the scale length is displayed as a numerical value.

  The worker who performs the cutting work visually recognizes the information displayed on the cutting position instruction screen, and first, virtually arranges a scale line that equally divides the entire length of the article into two, and the left end of the article is the reference scale. The cutting line Z is registered at a position where the ratio of the length of one scale between the reference scale line and the scale line adjacent to the right side is 72%, and the article is cut by the cutting line Z. . As a result, the operator can cut out a slice having an edible portion of approximately 145 g from a lump of fish of 500 g.

  When the division number N is calculated to be 2 or 4 in step S22, the arithmetic control unit 20 is configured to determine the division number N as a number obtained by further squaring the division number N. Also good. In this case, for example, as shown in FIG. 8, the reference scale line is not a scale line located at the left end of the article, but a scale line located immediately to the left of the cutting line Z.

(Embodiment 2)
A cutting position indicating device 10 according to Embodiment 2 of the present invention will be described. The cutting position indicating device 10 according to the first embodiment is configured to indicate a cutting position for cutting one piece having a weight close to the cut weight value M from one end of a lump of articles. On the other hand, the cutting position indicating device 10 according to the second embodiment is configured to instruct a cutting position for continuously cutting sections having a weight close to the cutting weight value M from one end of a lump of articles. ing. Since the hardware configuration of the cutting position indicating device 10 according to the second embodiment described below is the same as that of the cutting position indicating device 10 according to the above-described first embodiment, a duplicate description is omitted.

  Next, the flow of the cutting position instruction process of the cutting position instruction apparatus 10 according to the second embodiment will be described. The cutting position instruction process executed by the cutting position instruction apparatus 10 is a step of creating cutting position information as compared with the cutting position instruction process (FIG. 2) performed by the cutting position instruction apparatus 10 according to the first embodiment (FIG. 2). Except for step S9). Therefore, the flow of creating the cutting position information will be described below, and the processing related to other steps will be omitted because the description is duplicated.

  FIG. 9 is a flowchart showing a flow of creating cutting position information of the cutting position indicating device according to the second embodiment. As shown in FIG. 9, when creating the cutting position information, the arithmetic control unit 20 first obtains a division number N (step S31). Here, the arithmetic control unit 20 is configured to obtain the value of the scale division number N from the value registered in advance in the article model as information, but newly obtains the input numerical value by requesting input. Alternatively, it may be configured to calculate a value in which the weight of each scale division piece to be described later is smaller than the cut-out weight value M to obtain a value. It should be noted that the number of divisions N is preferably not more than 16.

  Next, the arithmetic control unit 20 calculates the weight of each scale division piece using the article model when the entire length of the article is divided into division pieces (scale division pieces) having the same length of the division number N. (Step S32). In addition, the boundary line of each division | segmentation piece and the both ends of an article | item become a scale line.

Subsequently, the arithmetic control unit 20 calculates the position of each of the cutting lines Z _{1 to} Z _k that continuously cuts the k pieces of the cut weight value M from the left end (one end) of the article using the article model. (Step S33). At this time, the calculation control unit 20 has established a reference scale line scale line located immediately to the left of each cutting line Z ₁ to Z _k, to the cutting line Z ₁ to Z _k from the reference scale line to the length of one notch The positions of the cutting lines Z _{1 to} Z _k are calculated as the length ratios D _{1 to} D _k (step S33).

Then, the arithmetic control unit 20 includes a scale division number N, and the reference scale line of the cutting line Z ₁ to Z _k, from the reference scale line to the length of one notch to the cutting line Z ₁ to Z _k the length of the Cutting position information including at least the ratios D _{1 to} D _k is created (step S34).

The cutting position instruction information including the cutting position information is output to the operation display 24 and displayed on the display unit 26. The cutting position indication information displayed on the display unit 26 includes a division number N or a scale line, cutting lines Z _{1 to} Z _k , a reference scale line for each of the cutting lines Z _{1 to} Z _k , and one scale.

The operator looks at the information displayed on the display unit 26, first, virtually arranges a scale line that equally divides the entire length of the article into the number N of scale divisions, determines a reference scale line, The cutting lines Z _{1 to} Z _k are registered at positions corresponding to the ratios D _{1 to} D _k with respect to one graduation on the right graduation line, and the article is cut along the cutting lines Z _{1 to} Z _k . Thereby, the operator can cut out k pieces of cut weight values M from a lump of articles.

(Application example 3)
Hereinafter, the flow of creating the cutting position information described above (steps S31 to S34) will be described by applying it to application example 3 using specific numerical values. FIG. 10 is a diagram for explaining the application example 3, and FIG. 11 is a diagram of a cutting position instruction screen according to the application example 3.

  As shown in FIG. 10, in the application example 3, it is assumed that a plurality of slices having a cutting weight value M of 150 g are cut out from a radish of 1000 g. When creating the cutting position information, the arithmetic control unit 20 first obtains a division number N (step S31). Here, the arithmetic control unit 20 reads the radish article model, and obtains the division number N (= 8).

  Next, the arithmetic control unit 20 calculates the weight of each scale division piece when the entire length of the article is divided into the scale division pieces of the scale division number N (= 8) using the article model (step S32). . Here, the weight of each division | segmentation division | segmentation piece was calculated with 80g, 100g, 105g, 115g, 170g, 150g, 145g, 135g sequentially from the left side.

Subsequently, the arithmetic control unit 20 sequentially positions k (= 6) cut weight values M (= 150) of the cutting lines Z _{1 to} Z ₆ from the left end (one end) of the article. Is calculated using the article model (step S33). The scale line immediately to the left of each of the cutting lines Z _{1 to} Z ₆ is a reference scale line, and the length ratios D _{1 to} D ₆ for one scale between the reference scale line and the right scale line are sequentially from the left side. It was calculated as 70%, 13%, 29%, 20%, 21%, and 26%.

Then, the arithmetic control unit 20 includes a scale division number N (= 8), and a reference scale line of the cutting line _Z 1 to Z _6, a reference scale line to cut the line _Z 1 to Z _k to the length of one notch Cutting position information including at least the length ratios D _{1 to} D _k is created (step S 34), cutting position instruction information including the cutting position information is generated, and is output to the operation display 24. Then, for example, a cutting position instruction screen as shown in FIG. 11 is displayed on the display unit 26 of the operation display 24. In the cutting position instruction screen shown in FIG. 11, the two-dimensional shape of the article based on the article model, the scale lines that serve as a guide for cutting, and the cutting lines Z _{1 to} Z ₆ are displayed as images, and the division number N ( = 8) and ratios D _{1 to} D ₆ of the length from the reference scale line to the cutting lines Z _{1 to} Z _{6 with} respect to one scale are displayed as numerical values.

The worker who performs the cutting work visually recognizes the information displayed on the cutting position instruction screen, and firstly arranges a scale line that equally divides the entire length of the article into eight parts, and the first from the left end of the article. with a measure of the position of the cutting line Z ₁ the proportion of length is 70% of one division from the scale line to second tick line, to cut the article by the cutting line Z _1. As a result, the operator can cut out a section of approximately 150 g from a lump of radish of 1000 g. In addition, if a position corresponding to each scale line of the article is marked, a plurality of sections can be continuously cut out.

(Combination example of cutting position indicating device 10 and suitable peripheral device)
As an example of a peripheral device that, when combined with the cutting position indicating device 10, can cut out a section of a desired weight from a lump of articles more accurately, an electronic scale having a function of arranging a scale line on the article 30. The electronic balance 30 used in the first embodiment and the second embodiment is a known electronic balance 30 that can measure the weight of an article placed on a weighing pan. By providing the electronic balance 30 with the function of arranging the scale line on the article, it is expected that the accuracy of the position of the scale line is increased and the accuracy of the cutting position of the section is increased.

  For example, the electronic balance 30 having the function of arranging scale lines on an article can be configured as follows. FIG. 12 is a diagram for explaining a configuration of a suitable electronic balance combined with a cutting position indicating device. As shown in FIG. 12, a measure 33 is provided on a weighing pan 31 of the electronic balance 30. The major 33 is provided with a cursor 32 indicating a scale line. The weighing pan 31 is provided with eight cursors 32 such that 1/8, 2/8,..., 8/8 and the entire length of the article are equally divided into eight, and these cursors 32 are adjacent cursors. It is mechanically configured so that it can move while maintaining a uniform spacing. In the weighing pan 31 of the electronic balance 30 thus configured, one end of the article is aligned with the start end of the measure 32, and the other end of the article is aligned with the 8/8 cursor 32, so that the total length of the article is accurately determined. A scale line that divides into eight equal parts can be easily visually recognized. In addition, it can replace with the weighing pan of an electronic balance, and can also provide a measure and a cursor on the cutting board used when cut | disconnecting articles | goods. In addition, the cursor is not limited to a mechanical configuration, and for example, the cursor position may be configured to be indicated by light emitted from a lamp or a laser emitter.

  The present invention can be used to cut a predetermined weight of a piece from a lump of an article, and the cut piece can be used as an object to be weighed, for example, with a combination weigher.
