Description

  The present invention relates to a label issuing device that prints and issues labels attached to foods such as fresh foods having a expiration date (or expiration date), lunch boxes, and side dishes.

  In general, labels are affixed to fresh foods such as meat, fish, vegetables, and eggs sold in supermarkets, and processed foods such as bento and side dishes. As shown in FIG. 13, the expiration date (or expiration date) 1 is printed on the label, together with product information such as product name, unit price, content, price, barcode, and date of manufacture. The expiration date 1 is usually determined based on the date and time when the food is manufactured or processed and the effective period during which the food can be stored.

As a conventional label issuing device capable of issuing such a label with a expiration date, it is provided with a time measuring means for measuring the date and time, and when the effective period of the food is input, the date and time after the expiration date has passed from the current date and time. It has been known to automatically calculate and print this date and time on a label as the expiration date (or expiration date) (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 08-224914

  However, when performing label issuance work using the conventional label issuance apparatus as described above, the work can be easily carried out for foods for which a product valid period in which the goods can be stored is determined in advance. For foods for which only the final date of the effective period is determined, the worker himself has to enter the effective period by calculating back the effective period from the current date and the final date of the effective period of the product. For this reason, there is a possibility that a label on which an incorrect expiry date is printed due to a calculation mistake in the product validity period is issued.

  For example, supermarkets often purchase meat that has been processed in advance by a processor, cut it, slice it, pack it, and sell it. However, there is a case where a label with the last date of the effective period is attached to the meat purchased from the processor, not the effective period that can be stored. In such a case, the clerk performing the packing operation considers the date of the label attached to the processed meat, that is, the last date of the validity period as the expiration date of the packed product using the processed meat, and the current date. The validity period must be calculated backward from the expiration date and entered into the label issuing device.

  The present invention has been made based on such circumstances. The purpose of the present invention is to print the expiry date without calculating the effective period even when only the final date of the effective period for which the product can be stored is known. It is an object of the present invention to provide a label issuing apparatus that can issue a label that can be issued and that can reduce the burden of label issuing work and reduce the frequency of issuing mislabels.

  The present invention provides a label issuing device that issues a label on which a due date based on a product validity period is printed together with product information such as a product name, etc., product information on a product to be issued a label, a due date based on the validity period of the product, etc. Label information storage means for storing data, input means for inputting date data relating to the effective date of the product, time measuring means for timing the date, date data timed by this time measuring means and input via the input means A period calculating means for calculating a period from the date data, a determining means for determining whether or not the period calculated by the period calculating means is valid as an effective period of the product, and determined by the determining means to be valid On the condition that the date data input through the input means is set in the label information storage means as the expiration date of the product, and the label Is obtained by a printing means for printing information stored in the broadcast storage means on the label.

  Here, the product effective period refers to a period during which the product can be stored. The expiration date is the date printed on the label as the expiration date or expiration date. The effective date refers to a date after the lapse of a period during which the product can be stored from the date of manufacture or processing.

  According to the present invention in which such a measure is taken, even when only the final date of the product valid period in which the product can be stored is known, the label printed with the expiration date can be issued without calculating the valid period. It is possible to provide a label issuing device that can reduce the work load and reduce the frequency of issuing mislabels.

  In the label issuing device having such a configuration, as shown in FIG. 4 in particular, product-specific information such as the product name, product classification, unit price, product validity period, etc. specified by the product number is previously stored for each product number for identifying each product. The set product number file 40 is downloaded from the host device and stored in the RAM 32. Here, the product validity period refers to a period during which the product specified by the corresponding product number can be stored. Here, the period storage means according to the present invention is constituted by the product number file 40 in the present embodiment.

  Further, as shown in FIG. 5, the RAM 32 temporarily stores various data such as the product number, product name, product classification, unit price, quantity, price, processing date, processing time, expiration date, expiration date, etc. A label data memory 51 for storing the data numerically, a numerical data memory 52 for temporarily storing numerical data set by the number keys 21 of the keyboard 12, and the like are formed. The processing date and the expiration date are both composed of 2-digit year data, 2-digit month data, and 2-digit day data. The processing time and the expiry date are both composed of 2-digit hour data and 2-digit minute data. Here, the label information storage means according to the present invention is constituted by a label data memory 51 in the present embodiment.

  Accordingly, when the CPU 30 of the label issuing device detects that the menu key 27 is operated, the CPU 30 displays the business menu list on the display 11 with the touch panel. Next, when it is detected that a label issuing operation is selected from various operation menus by a screen touch operation on the display 11 with the touch panel or a key operation of the cursor key 26 and the confirmation key 24, the label issuance of the layout shown in FIG. The screen 60 is displayed on the display 11 with a touch panel.

  The label issuing screen 60 includes a product number area 61, a product name area 62, a product classification area 63, a unit price area 64, a quantity area 65, a price area 66, a processing date area 67, a processing time area 68, a expiration date area 69, and a consumption time. Area 70 etc. are formed.

  Next, when the label issuing screen 60 is displayed, when it is detected that the product number of the product for which the label is to be issued is input by operating the numeric key 21 and the product number key 22 of the keyboard 12, the CPU 30 Product information such as product name, product classification, unit price, and valid period corresponding to the input product number is read from the product number file 40. Then, the input product number, product name, product classification, and unit price data are stored in the corresponding area of the label data memory 51. Further, the current date / time data counted by the clock unit 33 is acquired. Then, the date of this date / time data is regarded as the machining date, and the time is regarded as the machining time, and each is stored in the corresponding area of the label data memory 51. Further, the expiration date and time are calculated from the current date and time data and the valid period data read from the product number file 40 (expiration date calculation means). Then, the date and time data of the expiration date is stored in the corresponding area of the label data memory 51.

  Thereafter, the CPU 30 displays the data stored in each area of the label data memory 51 in the corresponding areas 61 to 70 of the label issuing screen 60 (display control means). Here, the display unit according to the present invention is configured by the display 11 with a touch panel.

  Next, when detecting that the expiration date area 69 or the consumption time area 70 of the label issuing screen 60 is touched, the CPU 30 executes the expiration date input process shown in the flowchart of FIG.

  First, the CPU 30 displays an expiration date input screen 71 having the layout shown in FIG. On the expiration date input screen 71, a expiration date area 72 and a days area 73, an expiration time area 74 and a time area 75, and a numeric input area 76 are formed. Further, touch key images such as a cancel button 77 and a confirm button 78 are displayed.

  Accordingly, the CPU 30 displays the date of the expiration date stored in the label data memory 51 in the expiration date area 72. In the days area 73, the number of days from the processing date to the expiration date is calculated and displayed. In the time limit area 74 for the expiration date, the time of the expiration date data stored in the label data memory 51 is displayed. In the time area 75, the time from the processing time to the expiration date is calculated and displayed. The expiry date input screen 71 may be displayed by switching to the label issuance screen 60 or may be displayed on the label issuance screen 60.

  Next, the CPU 30 waits for a numerical value to be set via the numerical key 21 as ST2. If the numerical value is entered, the numerical data is stored in the numerical data memory 52 as ST3 and displayed in the numerical value input area 76 of the expiration date input screen 71.

  Next, the CPU 30 determines whether or not a touch input of the expiration date input screen 71 has been performed in ST4. When touch input is not performed and the next numerical data is entered, the numerical data stored in the numerical data memory 52 is incremented by one digit, and the entered numerical data is stored as the least significant digit data. To do. Further, the numerical data of the numerical data memory 52 is displayed in the numerical value input area 76 of the expiration date input screen 71.

  When the touch input on the expiration date input screen 71 is detected in ST4, the CPU 30 determines the area on the screen 71 on which the touch input is made. If the touch input area is within the expiration date area 72 (YES in ST5), the date input process specifically shown in FIG. 7 is executed.

  That is, the CPU 30 determines whether or not numerical data is stored in the numerical data memory 52 as ST21. If no numerical data is stored, this date input process is terminated.

  On the other hand, if numerical data is stored, the CPU 30 determines whether the numerical data is 6 digits or less in ST22. If the number is 6 digits or less, the expiration date data is generated according to the number of digits.

  Specifically, when the numerical data is 1 digit or 2 digits, the numerical data is regarded as day data. Then, the lower two digits of the six-digit data stored in the expiration date area of the label data memory 51 are replaced with numerical data. In the case of 1 digit, the tens place is set to 0. When the numerical data is 3 digits or 4 digits, the lower 2 digits of the numerical data are regarded as day data, and the upper 1 or 2 digits thereof are regarded as month data. Then, the lower 4 digits of the 6-digit data stored in the expiration date area of the label data memory 51 are replaced with numerical data. In the case of 3 digits, the thousands place is 0. When the numerical data is 5 digits or 6 digits, the lower 2 digits of the numerical data are regarded as day data, the upper 2 digits thereof are regarded as month data, and the upper 1 digit or 2 digits are regarded as year data. Then, the 6-digit data stored in the expiration date area of the label data memory 51 is replaced with numerical data. In the case of 5 digits, the decimal place is set to 0. Thus, the CPU 30 generates the expiration date data according to the number of digits of the input numerical data.

  Next, the CPU 30 determines whether or not the expiration date generated as ST24 is a date that exists in the calendar. In the case of a date existing in the calendar, a period (number of days) from the current date timed by the clock unit 33 as ST25 to the expiration date indicated by the data generated in the process of ST23 is calculated. (Period calculation means). Then, in ST26, it is determined whether or not the calculation period is longer than 0 days and 999 days or less (determination means).

  Here, when the calculation period is greater than 0 days and less than or equal to 999 days, the CPU 30 determines that the calculation period is valid as the product valid period. The data displayed in the expiration date area 72 and the number-of-days area 73 of the expiration date input screen 71 as ST27, the expiration date generated in the process of ST23, and the product validity period data calculated in the process of ST25. Update to Also, the 6-digit data stored in the expiration date area of the label data memory 51 is updated to the expiration date data generated in the process of ST23 (expiration date setting means, second expiration date setting means). . Thereafter, if the numerical data in the numerical data memory 52 is cleared in ST28, the date input process is terminated.

  In ST22, when the numerical data is 7 digits or more, and in ST24, the expiration date is a date that does not exist in the calendar, and in ST26, the calculation period is 0 day or 1000 days or more. In this case, an error message is displayed on the display 11 with a touch panel. When it is detected that the erase key 23 has been input, the error message is deleted, the numerical data in the numerical data memory 52 is cleared, and this date input process is terminated.

  Thereafter, the CPU 30 returns to ST2 in FIG. 8 and waits for the next numerical data to be entered or for a touch input on the expiration date input screen 71 to be performed.

  When the touch input area of the expiry date input screen 71 is within the expiry date area 73 (YES in ST6), the CPU 30 executes the number of days input process specifically shown in FIG.

  That is, the CPU 30 determines whether or not numerical data is stored in the numerical data memory 52 as ST31. And when numerical data is not memorize | stored, this number of days input process is complete | finished.

  On the other hand, if numerical data is stored, the CPU 30 determines whether the numerical data is 3 digits or less in ST32. If the number is 3 digits or less, the expiration date is calculated according to the number of digits as ST33.

  Specifically, the numerical data is regarded as the number of days, and the date on the calendar that has passed the number of days of the numerical data from the current date counted by the clock unit 33 is set as the expiration date (expiration date recalculating means). Then, the data displayed in the expiration date area 72 and the number of days area 73 of the expiration date input screen 71 as ST34 is updated to the expiration date and the number of days of numerical data generated in ST33. Further, the 6-digit data stored in the expiration date area of the label data memory 51 is updated to the expiration date data generated in the process of ST33 (first expiration date setting means). Thereafter, if the numerical data in the numerical data memory 52 is cleared in ST35, the number of days input process is terminated.

  If the numerical data is 4 digits or more in ST32, an error message is displayed on the display 11 with the touch panel. When it is detected that the erase key 23 has been input, the error message is deleted, the numerical data in the numerical data memory 52 is cleared, and this number of days input process is terminated.

  Thereafter, the CPU 30 returns to ST2 in FIG. 8 and waits for the next numerical data to be entered or for a touch input on the expiration date input screen 71 to be performed.

  If the touch input area of the expiration date input screen 71 is within the expiration date time area 74 (YES in ST7), the CPU 30 executes the number of days input process specifically shown in FIG.

  That is, the CPU 30 determines whether or not numerical data is stored in the numerical data memory 52 as ST41. And when numerical data is not memorize | stored, this time input process is complete | finished.

  On the other hand, when numerical data is stored, the CPU 30 determines whether the numerical data is 3 digits, 4 digits, or any other as ST42. In the case of 3 or 4 digits, data on the expiration date is generated according to the number of digits.

  Specifically, when the numerical data has three digits, the upper one digit of the numerical data is regarded as hour data, and the lower two digits are regarded as minute data. Then, the upper 2 digits of the 4-digit data stored in the expiration date area of the label data memory 51 are replaced with the hour data, and the lower 2 digits are replaced with the minute data to generate the expiration date data. To do. When the numerical data is 4 digits, the upper 2 digits of the numerical data are regarded as hour data, and the lower 2 digits are regarded as minute data. Then, the upper 2 digits of the 4-digit data stored in the expiration date area of the label data memory 51 are replaced with the hour data, and the lower 2 digits are replaced with the minute data to generate the expiration date data. To do.

  Next, the CPU 30 determines whether or not the expiration date generated as ST44 is valid as a time. Here, if it is valid, ST45 calculates the time from midnight to the expiration date indicated by the data generated in the process of ST43. In ST46, the data displayed in the expiration date area 74 and the time area 75 of the expiration date input screen 71 is updated to the expiration date generated in the process of ST43 and the data calculated in the process of ST45. To do. Further, the 4-digit data stored in the expiration date area of the label data memory 51 is updated to the expiration date data generated in the process of ST43. Thereafter, if the numerical data in the numerical data memory 52 is cleared in ST47, this time input process is terminated.

  If the numerical data is 2 digits or less or 5 digits or more in ST42, and if the expiration date is invalid in ST44, an error message is displayed on the touch panel display 11. . When it is detected that the erase key 23 has been input, the error message is deleted, the numerical data in the numerical data memory 52 is cleared, and this time input process is terminated.

  Thereafter, the CPU 30 returns to ST2 in FIG. 8 and waits for the next numerical data to be entered or for a touch input on the expiration date input screen 71 to be performed.

  If the touch input area of the expiration date input screen 71 is within the expiration date time area 75 (YES in ST8), the CPU 30 executes the number of days input process specifically shown in FIG.

  That is, the CPU 30 determines whether or not numerical data is stored in the numerical data memory 52 as ST51. And when numerical data is not memorize | stored, this time input process is complete | finished.

  On the other hand, when numerical data is stored, the CPU 30 determines whether the numerical data is 2 digits or less in ST52. If the number is two digits or less, the time of consumption is calculated according to the number of digits as ST53.

  Specifically, the numerical data is regarded as time, and the time when the numerical data has elapsed since midnight is defined as the expiration date. Then, the data displayed in the expiration date / time area 74 and the time area 75 of the expiration date input screen 71 as ST54 is updated to the expiration date and the numerical data generated in the process of ST53. Also, the four-digit data stored in the expiration date area of the label data memory 51 is updated to the expiration date data generated in ST53. Thereafter, if the numerical data in the numerical data memory 52 is cleared in ST55, this time input process is terminated.

  If the numerical data is 3 digits or more in ST52, an error message is displayed on the display 11 with the touch panel. When it is detected that the erase key 23 has been input, the error message is deleted, the numerical data in the numerical data memory 52 is cleared, and this time input process is terminated.

  Thereafter, the CPU 30 returns to ST2 in FIG. 8 and waits for the next numerical data to be entered or for a touch input on the expiration date input screen 71 to be performed.

  On the other hand, when the touch input area of the expiration date input screen 71 is within the area of the cancel button 77 (YES in ST9), the CPU 30 inputs the updated expiration date as input in ST11 by the expiration date input process. And the data of the consumption time are returned to the state before the start of the expiration date input process. After that, if the expiry date input screen 71 is deleted in ST12, the label issue screen 60 is displayed again.

  Further, when the touch input area of the expiration date input screen 71 is within the area of the confirmation button 78, the updated expiration date and time data input by the expiration date input process and updated are not changed. The process proceeds to ST12. If the expiry date input screen 71 is deleted, the label issue screen 60 is displayed again. In this case, the data in the expiration date area 69 and the consumption time area 70 on the label issuing screen 60 are changed to the expiration date and time data updated by the expiration date input process.

  Here, the display control means according to the present invention is constituted by the CPU 30 that displays the expiration date input screen 71 on the liquid crystal display 11B of the display 11 with a touch panel. The operation means includes a touch panel sensor 11A of the display 11 with a touch panel capable of selecting and operating the expiration date area 72 and the number of days area 73 of the expiration date input screen 71.

  On the other hand, when the issue key 25 is operated while the label issue screen 60 is displayed, the CPU 30 edits the label print data based on each data stored in the label data memory 51. The label print data is output to the printer 13 and printed on a label. Here, the printing means according to the present invention is constituted by the CPU 30 and the printer 13 in the present embodiment.

  In the present embodiment configured as above, the current date is October 30, 2005, and the product effective period set in the product number file is 3 days as the last day of the product effective period. Assume that November 3 is designated. In this case, when the product number of this product is entered on the label issuing screen 60, the expiration date November 2, 2005 is calculated from the current date October 30, 2005 and the product validity period 3 days. Data “051102” corresponding to is displayed in the expiration date area 69.

  Therefore, the worker in charge performs a touch operation on the expiration date area 69. Then, the expiration date input screen 71 is displayed. Then, “051102” is displayed in the expiration date area 72 on this screen 71, and “3” is displayed in the days area 73.

  Therefore, the person in charge of the operation operates the numeric key 21 and inputs “1103” in order to input November 3 which is the last day of the effective period of the product. Thereafter, the date area 72 is touched. Then, the date input process shown in FIG. 9 is executed. That is, since the input numerical data is four digits, the upper two digits “11” are regarded as month data, and the lower two digits “03” are regarded as day data. As a result, data “051103” on the expiration date November 3, 2005 is generated. Further, a period of 4 days from the current date of October 30, 2005 to the expiry date of November 3, 2005 is calculated. Since the period 4 days is greater than 0 and less than or equal to 999, the expiry date November 3, 2005 is considered valid. Thus, the data in the expiration date area 72 on the expiration date input screen 71 is updated to “051103”, and the data in the days area 73 is updated to “4”.

  Therefore, the person in charge of the operation touches the confirmation button 78 on the expiration date input screen 71. Then, the screen of the display 11 with a touch panel returns to the label issuing screen 60. At this time, the data in the expiration date area 69 on the screen 60 is changed to “051103” corresponding to the expiration date November 3, 2005.

  Thereafter, when the person in charge of the operation operates the issue key 25, the label 1 of the product having the expiration date of November 3, 2005 is printed by the printer 13 and issued from the label issuing port 14.

  Thus, for example, in the case of the above-described specific example, conventionally, the worker in charge calculates the validity period of 4 days from the date of November 3 specified as the last day of the goods validity period and the current date of October 30 However, according to the present embodiment, it is sufficient to input the designated date as it is, so that the burden on the work peer can be reduced. In addition, since there is no possibility of issuing a label printed with an incorrect expiration date due to a calculation error in the period, an effect of reducing the frequency of issuing a mislabel can be achieved.

The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
For example, in the above embodiment, the product validity period is set for each product number identifying each product in the product number file 40, but the product validity period may be set for a product classification unit for classifying each product. Further, the layout of the label issue screen 60 and the expiration date input screen 71 is not limited to that of the above-described embodiment.
