Description

  The present invention relates to a weighing device and a weighing method for weighing the mass of an article and printing the weighing result on a printing medium.

  When measuring mass in transactions or proofs, weighing with a scale (measuring device) that meets the criteria of the Measurement Act is required. In this case, the measurement result outside the measurement compensation range (measurement range) based on the measurement law cannot be output (label printing or the like) as it is.

  Further, Patent Document 1 discloses that a warning is issued when the measured value exceeds the allowable range of the target weight, but there is no description about a case where the measured value falls below the measurement range based on the measurement law. There is no.

JP 61-142135 A

  In the above cases, for example, it is possible to perform label printing by manual input of the measurement value, but it is easy to cause an erroneous operation or an input error, and the work efficiency of the measurement work is reduced by printing the incorrect measurement value. There was a problem such as.

  The present invention has been made in view of the above points, and its purpose is in a case where normal printing cannot be performed (for example, a measurement result outside the measurement compensation range based on the measurement law). Even if it exists, it is providing the weighing | measuring apparatus and weighing | measuring method which can print the measurement result without an erroneous operation and an input mistake efficiently, without performing manual input separately.

The present invention provides a weighing means for weighing the mass of an article, an input means for inputting a numerical value, and the mass of an article weighed by the weighing means is within the weighing compensation range of a weighing device based on the weighing law. The first printing means for printing on the printing medium based on the mass, and the mass of the article weighed by the weighing means is outside the weighing compensation range of the weighing device based on the weighing method, and numerical, and that it has accepted the input means, is characterized in that it comprises a second printing means for printing on Printout medium.
According to the present invention, in addition to the normal printing operation (first printing means) for printing the mass of the article on the printing medium, the numerical value input by the input means and the fact that the input means has been received are combined on the printing medium. because have other printing operation for printing (second printing means), in the case of weighing results entering the metering compensation within range based on weighing method prints a normal printing medium using a first printing means, said metering compensation When the measurement result is out of the range , the printing medium displaying the fact can be printed using the second printing means. In other words, even if the measurement result is out of the measurement compensation range , the data can be used as it is and printed on a print medium (however, the display content is different from that of a normal print medium). It becomes unnecessary, and it becomes possible to efficiently print the measurement result without any erroneous operation or input error on the print medium.

Further, the present invention is characterized in that the input of numerical values by the input means is validated when the mass of the article weighed by the weighing means is outside the weighing compensation range of the weighing device based on the weighing law.
Thus, the mass of the metered articles in the case of out of the metering coverage, is enabled (printing comprising a display it is understood that the total amount compensation range) printed by the second printing means. That is, even if the measurement result is out of the measurement compensation range based on the measurement method, the measurement result can be used for output as it is.

The present invention is characterized by comprising display means for displaying the weight of the weighed article, the entering-force means on the same screen.
Thereby, it is possible to perform printing by the second printing unit using the input unit while confirming the mass displayed on the same screen.

Further, the present invention provides a weighing step for weighing the mass of the article, an input step for inputting a numerical value, and the mass of the article weighed by the weighing step is within the weighing compensation range of the weighing device based on the weighing law. A first printing step for printing on a printing medium based on the mass, and if the mass of the article weighed in the weighing step is outside the weighing compensation range of the weighing device based on the weighing method, input in the input step said number, it is characterized in that and a second printing step of printing the indicia shaped medium and that it has accepted the input step.

  According to the present invention, even when normal printing cannot be performed (for example, when the measurement result is outside the measurement compensation range based on the measurement law), a predetermined operation is accepted together with the measurement result. The measurement result can be used for printing as it is by printing on the printing medium together with the fact (for example, instructing printing as manual input). This eliminates the need for complicated operations such as manual input, realizes an efficient weighing operation, and eliminates input errors.

The headquarters management device 130 is a computer (for example, a server) that controls the weighing system 1 and automatically collects and manages the weighing data collected at each store at a predetermined time such as midnight. Analyze etc.

  FIG. 2 is a schematic external view showing the weighing device 10, the scanner 50 and the weighing unit 60 connected thereto. As shown in the figure, the weighing device 10 has a display unit / input unit 13 and a key input unit 15 installed on the top of the base unit 11, and a label issuing port 17 installed on the front surface of the base unit 11. It is configured. In addition, a code reading scanner 50 is connected to the weighing device 10 via a cable (may be wireless), and an article weighing unit 60 is also connected via a cable (may be wireless). The measuring device 10 is installed in a garbage collection place such as a food manufacturing factory or a supermarket, for example, and measures various collected wastes (trash) for each department or type of waste discharged. Then, the measured measurement value, department name, etc. are printed on a label (print medium) and attached to the measured waste. This makes it possible not only to easily manage the amount and source of waste, but also to track the history of waste generation, and to reliably manage the source of waste by attaching labels to the waste. It is a system.

  FIG. 3 is a diagram illustrating an example of a functional block diagram of the weighing device 10. As shown in the figure, the weighing apparatus 10 stores a CPU 21 that controls the operation of the weighing apparatus 10, a ROM 23 that stores a control program executed by the CPU 21, and various types of information such as a measurement compensation range based on the measurement law. The RAM 25 displays various information such as weighing results of the weighing device 10 on the screen, and the display unit / input unit 13 that performs input / operation by touching the screen, and key input that operates the weighing device 10 by key operation. A communication unit 29 that communicates with the unit 15, the scanner 50, a communication unit 29 that communicates with a higher-level model (and other various devices) such as the store management device 100 and the headquarter management device 130, and a weighing unit 60. An A / D converter 31 that performs A / D conversion on an input signal from the load cell 67 that constitutes the printer; Equipped and are configured. Each component is connected to each other via a bus 35. The CPU 21 reads the control program stored in the ROM 23 and various information stored in the RAM 25, and controls each unit based on the read control program and various information. Further, the CPU 21 stores necessary information in the RAM 25. In this example, a linerless printer is used as the printing unit 33. The display unit / input unit 13 is a display unit for displaying an image, and at the same time, is an input unit including a touch panel provided in the display unit / input unit 13, and more specifically, in a screen displayed by the display unit. An input means is displayed. The key input unit 15 is also an input means.

  Returning to FIG. 2, the measuring unit 60 includes a measuring unit main body 61 and a slope 63. The weighing unit main body 61 is configured by placing two bar scales 69a and 69b in parallel at a predetermined interval and placing the weighing pan 71 over the two bar scales 69a and 69b. ing. Each of the bar scales 69a and 69b includes a pair of load cells. Then, the output signal lines 73a and 73b connected to the two bar scales 69a and 69b are combined at the external junction box 75 and pulled out as one output signal line 77, and connected to the A / D conversion unit 31 of the weighing device 10. doing.

  On the other hand, a slope 63 for guiding and placing the container on the weighing pan 71 of the weighing unit main body 61 is connected and fixed to one side portion of the weighing unit main body 61. The slope 63 is formed so as to reach the height of the weighing pan 71 with a gentle gradient. Although not shown, the container is configured by attaching a wheel to the bottom of a large plastic container for storing waste. This container is a container for separating and storing waste, and is transferred onto the weighing unit main body 61 using the slope 63. However, the container is not limited to having a wheel, and for example, a container having a shape that is carried and placed on the weighing pan 71 by hand may be used. Further, a resin bag such as a plastic bag may be used instead of the container. Also good. In such a case, no slope is required.

  A bar code table (not shown) is installed near the weighing device 10. The barcode table scans instead of multiple barcodes that identify each department name (department) of a company or facility, multiple barcodes that identify the type of waste, and the “OK” button described below. A bar code for “confirmed transmission” is displayed.

  Next, the operation of the weighing system 1 will be described. In the following description, the upper limit of the weighing compensation range based on the weighing method of the weighing device 10 used in this example is 150 kg, the scale (d) is 50 g, and the lower limit (minimum measurement amount) (= 20 d) is 1.00 kg. Here, the scale (d) is the smallest unit of measurement that can be displayed. The lower limit (minimum display amount) is the minimum measurement value that can be displayed as defined by the Measurement Law, and the value varies depending on the class of the measurement law. In this case, the lower limit is 20d (= 20 counts × scale amount (d), that is, 20d = 20 × 50 (g) = 1.00 kg). FIG. 4 is an operation flowchart showing an example of the operation of the weighing device 10. First, waste is brought in. The waste may be stored in the container and carried in. In this example, a resin bag is used and the tare amount is 0.00 kg.

  Next, the collection operator confirms the department name and type of waste in the company from the person who brought in the waste, specifies the department name (for example, food court) and the type of waste (for example, garbage), and measures The barcode of the corresponding department name and the barcode of the waste type corresponding to the barcode table installed in the vicinity of the apparatus 10 are read by the scanner 50 and input to the weighing apparatus 10 (step ST1).

  Next, the waste stored in the resin bag is placed on the weighing pan 71 of the weighing unit 60, and the weighing is started (step ST2). Then, the process waits for the measurement value to stabilize (step ST3), and completes the measurement at a stable stage (step ST4).

  Then, the measured measurement value (measurement result) is displayed on the display / input unit 13 of the weighing apparatus 10 (step ST5). The displayed measured value is a net mass obtained by subtracting the tare mass from the measured total mass. In addition to the net mass, the tare mass is displayed together on the display / input unit 13. FIGS. 5 and 6 show screen examples G1 and G2 of the weighing screen displayed on the display / input unit 13 at this time. The screen example G1 shows a case where the measured value (net mass) is 10.00 kg. The screen example G2 shows a case where the measured value (net mass) is 0.30 kg. That is, the screen example G1 shows the case where the measurement value is within the measurement compensation range based on the measurement law, and the screen example G2 shows the case where the measurement value is outside (below) the measurement compensation range based on the measurement law. Yes.

  When the measurement value is within the measurement compensation range based on the measurement law as in the above screen example G1, if the “OK” button g1 in the screen example G1 is pressed (step ST6), as shown in FIG. A normal label R1-1 is issued from the label issuing port 17 of the weighing device 10 (steps ST7 and ST8). The label 1-1 includes a department name r1 input in step ST1, a waste type r2, a net mass r3 calculated in step ST4, a current date and time r4, and a message r5 indicating “Weighing complete”. Is displayed. And this label R1-1 is affixed on a waste material, it carries out from the weighing pan 71, and moves to a garbage collection place. When the measurement value becomes “0”, the display of the display / input unit 13 is reset, and the next waste can be carried in. Instead of pressing the “confirm” button g1, pressing of the confirm key in the key input unit 15 or scanning of the “confirm transmission” barcode in the barcode table by the scanner 50 may be used ( The same applies to the pressing of “determine” buttons g2 and g3 described below).

  On the other hand, in step ST5, when the measurement value is outside the measurement compensation range based on the measurement law as shown in the screen example G2, when the “confirm” button g2 in the screen example G2 is pressed (step ST6), FIG. A weight manual input screen (screen example G3) as shown in FIG. 6 is displayed (steps ST7 and ST9). The screen example G3 of the weight manual input screen is a screen in which the measured measurement value is displayed in the center, and the measurement value can be changed by manual input from the key input unit 15 in this state. In other words, when the measurement value is outside the measurement compensation range based on the measurement law, even if the “OK” button g2 in the screen example G2 is pressed, the label is not automatically issued and the automatic label issuance is stopped. A screen example G3 is displayed. Conventionally, when the measurement value is out of the measurement compensation range based on the measurement law, even if the “OK” button g2 in the screen example G2 is pressed, the screen example G3 of the weight manual input screen is not displayed. There was no message or notification, and the screen example G2 was kept as it was, and only waiting for the measurement value to be within the measurement compensation range (or waiting for some other operation to be performed).

  When the “confirm” button g3 displayed in this screen example G3 is pressed (that is, when a predetermined operation is performed or an operation for canceling the stop of label printing is performed), the automatic label issuance stop is canceled. A manually input label R1-2 as shown in FIG. 9 is issued from the label issuing port 17 of the weighing device 10 (steps ST10 and ST11). The label R1-2 includes the department name r1 input in step ST1, the waste type r2, the net mass r3 calculated in step ST4, the current date and time r4, and a message r5 of “Weighing complete”. In addition, the matter that the measurement result is out of the measurement compensation range (in this example, “manual input as proof that the press (predetermined operation) of the“ confirmation ”button g3 in the screen example G3 which is an input means is accepted) Is displayed) r6 is displayed. And this label R1-2 is affixed on a waste, it carries out from the weighing pan 71, and moves to a garbage collection place. When the measurement value becomes “0”, the display of the display / input unit 13 is reset, and the next waste can be carried in.

  On the other hand, when the “clear” button g4 displayed in the screen example G3 shown in FIG. 8 is pressed, the process returns to step ST2 and the measurement is performed again (steps ST10 and ST12). On the other hand, when the “Cancel” button g5 is pressed, the operation flow is returned to the beginning, and the operation is started again from the beginning (step ST13).

  The contents of the performance data stored in the weighing device 10 are transmitted to the store management device 100 and the headquarter management device 130, which are higher-level devices, and are classified, tabulated, and analyzed. Of course, the classification, tabulation, and analysis of the contents of the result data may be performed by the weighing device 10 itself (single unit). In the case where “manual input” is printed on the label, the result data may also include the fact.

  As described above, the weighing device 10 determines whether the weighing unit weighing the article (the weighing unit 60 or the CPU 21 that controls the weighing unit) and the weighing value measured by the weighing unit are stable. Determining means (CPU 21 that performs step ST3, etc.), and when determining that the measurement value is stable by the determining means, or an operation for printing issuance ("Confirm" button in the screen example G1 shown in FIG. 5) first press means (CPU 21 etc. that performs step ST8 etc.) that prints the mass of the article weighed by the weighing means on the label R1-1 when the press of g1 is received (when step ST6 etc. is performed). Input means (display unit / input) that determines that the measurement value is stable by the determination means and receives a predetermined operation (such as pressing the “confirm” button g3 in the screen example G3 shown in FIG. 8) When the predetermined operation is received by the touch panel 13 (when performing step ST10 or the like), the weight of the article weighed by the weighing unit and the fact that the predetermined operation has been received (“manual input” r6 shown in FIG. 9). And a second printing means (such as the CPU 21 that performs step ST11) that prints on the label R1-2.

  In this way, the weighing device 10 combines the mass of the article and the fact that the predetermined operation has been received, in addition to the normal printing operation (first printing means) for printing the mass of the article on the label R1-1. Since there is another printing operation (second printing means) for printing on R1-2, for example, in the case of a measurement result that falls within a predetermined measurement range (measurement compensation range based on the measurement method as in the above embodiment) A normal label R1-1 is printed using one printing means, and if the measurement result is out of the predetermined measurement range, the label R1-2 indicating that can be printed using the second printing means. That is, even if the measurement result is out of the predetermined measurement range, even if the label R1-2 is printed using the data as it is, the display of “manual input” r6 that is different from the normal label R1-1 is displayed. In addition, there is no problem even if this measurement result is displayed as it is. Since the measurement result can be printed as it is, there is no need for an operation / work such as separate manual input, no erroneous operation or input error occurs, and the measurement result can be efficiently printed on the label R1-2. It becomes possible. In the above example, “manual input” r6 is displayed as an indication that a predetermined operation has been accepted. However, instead of “manual input” r6, “under measurement compensation range” or “measurement compensation” Other various indications such as “over range” or “outside of measurement compensation range” may be used.

  In addition, the weighing device 10 inputs a predetermined operation (such as pressing the “confirm” button g3) when the mass of the article weighed by the weighing means is outside the weighing compensation range of the weighing device based on the weighing law. Is provided with an input means (such as a touch panel of the display / input unit 13 for displaying the screen example G3). Thus, when the weight of the weighed article is outside the weighing compensation range, printing by the second printing unit (for example, printing including a display that indicates that the weighing compensation range is outside) is possible.

  Also, the weighing device 10 performs label printing by the first printing means when the mass of the article weighed by the issuing means is outside the weighing compensation range of the weighing device based on the weighing law. Means for stopping (CPU 21 etc. executing steps ST7, ST9, etc., so as not to automatically issue labels even if the “OK” button g2 in the screen example G2 is pressed. Screen example G3 is displayed). Thus, normal label printing by the first printing means is performed only when the weight of the weighed article is within the weighing compensation range. On the other hand, when the weight of the weighed article is outside the weighing compensation range, label printing by the second printing means (for example, printing including a display indicating that it is outside the weighing compensation range) can be performed. As described above, when the measurement result is out of the predetermined measurement compensation range, the output of the measurement result is temporarily stopped, and the stop is performed by a predetermined operation (operation of pressing the “OK” button g3 in the screen example G3). Since label printing (step ST11) is performed when cancelled, it is possible to select whether output is possible or not as desired.

  Further, the weighing device 10 displays the weighed mass and input means (a touch panel of the display / input unit 13) for performing a predetermined operation (such as pressing the “confirm” button g3) on the same screen (screen example G3). Display means (display unit / input unit 13) for displaying is provided. Accordingly, it is possible to instruct printing by the second printing unit using the input unit while confirming the mass displayed on the same screen.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. It should be noted that any configuration not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the weighing device 10, the printing unit 33 that prints a predetermined matter including the weighing result on a printing medium is installed as the printing unit. However, the present invention is not limited to this, and for example, outside the weighing device 10. A configuration may be adopted in which data is transmitted to a separately provided device (for example, a separately provided printing device) to print. In this case, an external printing device also constitutes a part of the weighing device 10.

  Moreover, although the case where this invention was utilized for the measurement of waste was demonstrated in the said example, various goods (foodstuff etc.) other than a waste are measured (for example, a measuring price attaching machine, a measurement packaging price attaching machine, etc.). The weighing device according to the present invention may be used. In the above example, the weighing unit is configured using a bar scale. However, the measuring unit may be configured using other various scales such as an ordinary platform scale.

  Further, in the above example, after the weighing is completed in step ST4 shown in FIG. 4, the “confirm” buttons g1 and g2 in the weighing screen (screen examples G1 and G2) displayed in step ST5 are pressed in step ST6. However, step ST6 is omitted (ie, the “OK” buttons g1 and g2 are not displayed in the screen examples G1 and G2), the measurement is completed in step ST4, and the measurement value is displayed. Automatically enters a normal label (steps ST7 and ST8), and automatically displays a screen example G3 of a weight manual input screen if it is not within the weighing compensation range (step ST7). 9).
