Abstract

PURPOSE:To print always correct valid terms or days by a method wherein at the time of issuing labels, the valid terms of a pertinent article of trade can be varied corresponding to ambient atmospheric temperature which is detected by a temperature detecting means. CONSTITUTION:When a prescribed time (for example, 0:00 P.M.) comes, an ambient atmospheric temperature, a so-called air temperature, in the surroundings measured by a temperature sensor 15 is detected, and air temperature data at the prescribed time for the last one week is controlled by an air temperature control table 43. An average temperature at the prescribed time for the last one week is calculated based on the data in the air temperature control table 43, and stored constantly in an average air temperature memory 44. In this state, when a label issuing is commanded by key inputting of an article number of a pertinent fresh food, a valid term corresponding to the average air temperature stored in the average air temperature memory 44 is selected, a valid day is calculated based on the valid term and print output on a label.

Description

[Detailed description of the invention] [Industrial application field] The present invention applies prices to fresh foods such as meat and fish.

[Prior Art] Conventional label issuing devices of this type have a product number file in which the product name, price, expiration period, etc. are set in advance for each product number, and the product number of the product to be labeled is entered from the keyboard. It is known that when a key is entered manually, the corresponding product name, price, expiration date, etc. are retrieved from the product number file and printed out on a label. It also has a built-in clock circuit that stores the current date, and when the label is issued, reads the date and time stored in the clock circuit, and automatically calculates the effective date from the current date and time and the product's validity period.
There are also some that are printed on the label.

By the way, fresh foods such as meat and fish last a long time when the temperature is low, such as in the winter, but they spoil quickly when the temperature is high, such as in the summer. Therefore, the shelf life of these fresh foods cannot be determined unconditionally, but depends on the ambient temperature.

Problem to be solved by the invention C] However, in conventional label issuing devices of this kind, the validity period is fixed and preset for each product, and can be changed depending on the ambient ambient temperature. It wasn't something. If you try to vary the temperature by considering the ambient temperature, you will have to change the settings in the product number file each time, which will be very complicated. For this reason, in the past, the effective period was set regardless of changes in the surrounding atmospheric temperature, and this sometimes resulted in an incorrect period of validity.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a label issuing device that can automatically vary the validity period of each product depending on the ambient atmospheric temperature and can always issue labels with accurate validity periods or dates printed on them. be.

[Means for Solving the Problems] The present invention provides a temperature detection system for detecting the surrounding atmospheric temperature in a label issuing device that prints and issues the product name, price, etc., as well as the expiration date or expiry date of the product on a label. means, a validity period storage means for storing a validity period corresponding to the ambient temperature for each product; and a validity period storage means for storing a validity period corresponding to the ambient temperature for each product; and a validity period of the corresponding product from information stored in the storage means based on the ambient atmospheric temperature detected by the temperature detection means when the label is issued. and a printing control means for printing on the label the validity period selected by the selection means or the validity date calculated based on the validity period.

The validity period selection means preferably selects the validity period of the product from the information stored in the storage means based on the average ambient temperature over a certain period of time detected by the temperature detection means when the label is issued.

[Function] By taking such measures, the validity period of the product is changed depending on the ambient temperature detected by the temperature detection means when the label is issued.

For example, if the validity period storage means stores the validity period of a certain product when the ambient temperature is below a degree Celsius as A days, and the validity period when the ambient temperature is above a degree Celsius is stored as B days (BAA), when the label for that product is issued, the temperature If the surrounding atmospheric temperature detected by the detection means is below a degree Celsius, the effective period will be A days, and if it is above a degree Celsius, the effective period will be B days.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram showing the schematic configuration of the label issuing device, in which a CPU (central processing unit) serves as the control unit main body.
1 controls a storage section and a controller section via a pass line 2. Here, the storage unit is a ROM in which program data, character generator data, etc. are stored.
(Read-only memory) 3, RAM (Random Access Memory) 4 in which various memories for data processing are formed, and the product name and price corresponding to the product number of each product.

A product number file 5 is provided in which the validity period and the like are preset. On the other hand, the controller section includes a keyboard controller 7 that inputs key signals from the keyboard 6.
, a display controller 9 that drives and controls the display 8 to display the item number, weight, price, etc. of the product, and a printer 10 that prints on the transported label paper and issues the label.
A printer controller 11 is provided to drive and control the printer.

Further, the CPUI is configured to take in date and time data from a clock circuit 12 that measures the date and time.

The weighing section 13 is for weighing products sold by weight and is composed of a load cell, etc.
The f1ffi data is converted into a digital count value by an A/D (analog/digital) converter 14 and then input to the CPUI.

The temperature sensor 15 is for measuring the ambient atmospheric temperature (air temperature) and is composed of a thermistor or the like, and the temperature data measured by the temperature sensor 15 is sent to the temperature conversion circuit 16.
After being converted into a digital count value at
It is designed to be input into the UI.

As shown in Figure 1, the product number file 5 includes, in correspondence with the product number (4 digits), the department code (2 digits) indicating the department to which the product belongs, the product name (20 digits), and the amount ( 6 digits)
and a fixed amount flag (1 digit) are set. Here, the fixed price flag is set to "1" when the product is a fixed price product, and reset to "0" when the product is sold by weight, that is, the fixed price product (fixed price flag - "1°")
In the case of , the price per piece is set in the amount area, and in the case of a product sold by weight (fixed price flag - "0°"), the price per unit weight, so-called unit price, is set.

In addition, in the product number file 5, as shown in the figure, the validity period (3 digits) is divided into 5 stages corresponding to the ambient temperature T for each product.
is now set.

(Validity Period Storage Means) As shown in FIG. 3, the RAM 4 includes a print buffer 41 for temporarily storing label print data, a work buffer 42 used for various calculation processes, etc., as well as the temperature sensor. A temperature management table 43 that stores the temperature at a predetermined time measured by 15 for the past week, and an average temperature memory 44 that stores the average temperature of the temperature at a predetermined time managed by this table 43 are provided. .

As shown in FIG. 4, the keyboard 6 includes numeric keys 61 for inputting numerical data such as "0" to "9", a clear key 62 for clearing numerical data, and a clear key 62 for clearing numerical data. A product number key 63 indicates that the numerical data is a product number, and a department key 64 indicates that the numerical data is a department code.
, a multiplication key 65 that indicates that the numerical data is a multiplier.
, an issue key 66 that instructs to issue a label, a fixed price key 67 that indicates that it is a fixed price product, a date key 68, and a # key 6.
Various function keys such as 9 are arranged.

The CPU then periodically reads the time measured by the clock circuit 12, and when a preset time (for example, 12:00 p.m.) arrives, executes the interrupt routine shown in FIG. The program is set as follows. First, the temperature at a predetermined time measured by the temperature sensor 15 is detected via the temperature conversion circuit 16 (temperature detection means).

Then, the stored contents of the temperature management table 43 are moved back one day at a time, and the temperature data detected this time is stored in today's area, which is now an empty area. Next, the temperature management table 43
The average temperature at a predetermined time is calculated from the temperature data stored in the temperature data. Then, the calculated average temperature is stored in the average temperature memory 441, and this interrupt routine is ended.

Further, the CPUI is programmed to perform the label issuing process shown in FIG. That is, when numerical data is entered manually using the number keys 61 of the keyboard 6 and then the product number key 63 is entered manually to enter the product number of the product for which a label is to be issued, the department 1 corresponding to the input product number is entered from the product number file 5. The product name, price, fixed price flag, and various validity periods are called up and stored in the work buffer 42.

Then check the flat rate flag. If the flag is reset here, the label will be issued for the product sold by weight.
The weight value of the product weighed by the weighing section 13 is taken in via the A/D converter 14. Then, its weight value and unit price (
A price is calculated from the amount data) and stored in the work buffer 42.

At this time, the product name, unit price, weight, price, etc. are displayed on the display 8.

On the other hand, if the fixed price flag is set, the label is issued for a fixed price product, so the amount data is stored in the work buffer 42 as a price.

At this time, the product name, price, etc. are displayed on the display 8.

Thereafter, when the issue key 66 is pressed from the keyboard 6 to instruct label issue, the CPU reads the average temperature T stored in the average temperature memory 44,
The valid period corresponding to the temperature range including the average temperature T is selected from the storage contents of the work buffer 42. (
Effective Period Selection Means) Then, the current date is read out from the clock circuit 12 as the processing date, and the effective date is calculated from this processing date and the selected effective period and stored in the work buffer 42. After that, the label print data (
Product name, price, processing date.

effective date, etc.) and set it in the print buffer 41. Then, the printer 10 is driven and controlled to print out the label print data in the print buffer 41 onto a label (print control means), and the label is issued, and this processing is completed.

In this embodiment configured in this way, for fresh foods such as meat and fish whose shelf life is lengthened or shortened depending on the ambient temperature T, the ambient temperature T is 0°C.
Validity period A when the temperature is 0℃ or more and less than 10℃ 81 Validity period when the temperature is 10℃ or more and less than 20℃ Cl2 Validity period when the temperature is 20℃ or more and less than 30℃ 0130℃
The validity period E in each of the above cases is determined and set in advance in the product number file 5.

On the other hand, at a predetermined time (for example, 12:00 p.m.) every day, the surrounding atmospheric temperature, so-called air temperature, measured by the temperature sensor 15 is detected, and the temperature management table 43
Temperature data at a predetermined time for the past week is managed.

Then, from the data of this temperature management table 43, the most recent
The average temperature at a predetermined time of the week is calculated and always stored in the average temperature memory 44.

In this state, when issuing a label by manually inputting the product number of the fresh food, the average temperature memory 4
The validity period corresponding to the average temperature stored in 4 is selected, and the validity date is calculated based on this validity period and printed on the label.

In other words, when the average temperature is less than 0℃, the validity period is A.
If the temperature is 0°C or more and less than 10°C, it will be B days, and if the temperature is 10°C or more and less than 20°C, it will be C days, and 2 days.
When the temperature is 0°C or more and less than 30°C, it will be D days, and if it is 30°C or more, it will be B days.

For example, for the product name "beef loin", the ambient temperature T is 0.
℃ or more and less than 10℃, the validity period is 4 days, and 10℃
If the validity period is 5 days when the temperature is above 20℃, if the average temperature at a specified time in the past week is 0℃ or more and below 10℃, a label as shown in Figure 7 will be issued, and if the average temperature is 10℃ If the temperature is above 20°C, a label as shown in Figure 8 will be issued.

In this way, according to this embodiment, when a label is issued, the validity period of the product can be automatically changed according to the average temperature at a predetermined time measured by the temperature sensor 15, thereby eliminating the need for complicated setting change operations. It becomes possible to issue labels with accurate expiration dates or expiration dates that take into account temperature changes without having to do so.

In the above embodiment, the average temperature at a predetermined time was calculated and the validity period was made variable depending on the average temperature. Furthermore, it is also possible to calculate the average and make the validity period variable. The gist of the present invention also includes a system in which the temperature at the time of label issuance is input each time, and the validity period is varied depending on the temperature. However, in this case, the validity period may be inaccurate because it responds to temporary temperature fluctuations.

[Effects of the Invention] As detailed above, according to the present invention, the validity period of each product can be automatically changed according to the surrounding atmospheric temperature, and the label can always have an accurate validity period or date printed on it. It is possible to provide a label issuing device that can issue labels.
