Description

[Detailed Description of the Invention] This invention is a packaged product in which an indefinite amount of products is packaged and a label with individual values such as weight and price printed on it is attached. If the weight changes due to factors such as evaporation, the product is equipped with a function that anticipates this and corrects the value printed on the label when weighing at the time of packaging to a value corresponding to the changed weight. , relates to a weighing device.

Generally, an indefinite amount of packaged products is weighed using a digital scale or the like, and a label with the weight, unit price, price, etc. printed thereon is attached by a label printing machine linked to the scale.

Therefore, if the actual weight of the product and the weight printed on the label are different during a product transaction, various troubles may occur. In other words, even if the package is accurately weighed and the value is printed on the label, the weight of the product may change depending on the elapsed time until the time of transaction, the storage environment of the product, etc. For example, the weight value of a product containing a large amount of water changes due to evaporation of water, and the weight value of a product that easily absorbs water changes due to absorption of water in the air. In particular, in the case of the former, it is considered a problem as it may cause consumers to mistrust the product as it is called a weight loss food or a natural weight loss product. Measures are being taken. Therefore, manufacturers, metrology research institutes, etc. are also investigating how the weight of products changes with the passage of time, changes in storage environment, etc. Therefore, in view of the above circumstances, the present invention is based on the ratio of the weight at the time of packaging and the expected weight at the time of transaction, which is the result of this survey, that is, the natural decrease rate (to) or increase rate (to) at the time of weighing. This system automatically corrects the measured weight value and prints the corrected weight, price, etc. on the label.

As a result, when a product is traded, the weight value changes, but since the change is corrected at the time of weighing, it is possible to trade properly within the weight tolerance.
As will be described later, this correction method can be roughly divided into two types: one in which only the weight value is corrected to a numerical value after an expected change, and the other in which the unit price is corrected in addition to the weight value. Each of these will be explained below based on examples. In the embodiment shown in FIG. 1, only the weight value is corrected using a set correction rate and printed on the label.

In the configuration of this embodiment, reference numeral 1 denotes a correction factor reading section, and this function is to automatically read out the correction factor when a product name stamp is attached to the label printing and issuing device. As a specific means, for example, a magnetic memory piece may be added to the product name stamp, and the correction factor may be read out using a magnetic sensor or the like when the product name stamp is attached. Further, 2 is a weight value correction unit to which the weight value of the item weighed by the weighing device 3 and the read correction factor are input, and the unit calculates the product of these two input signal values. A corrected weight value is output. In addition, when the signal is input at the loss rate (or decrease rate), the correction rate -1
The weight value correction unit 2 also calculates the weight loss rate (or weight loss rate) etc.
It is done in. Then, the corrected weight value is sent to the label printing and issuing device 4, and is printed as a weight value on the label attached to the item. Reference numeral 5 denotes a price calculating section which calculates a price from the corrected weight value and the unit price sent from the unit price setting section 6.

This price is sent to the label printing and issuing device 4 and printed on the label as a price. 7 is a decoder for displaying the output of each arithmetic circuit on a display, and each output is converted into a signal corresponding to the display.

The net weight display 8 shows the actual weight value, the price display 9 shows the printed price, and the unit price display 10 shows the set unit price. , the corrected weight to be corrected and printed, and the read correction factor are digitally displayed on the correction factor display 12, respectively. That is, in this correction method, the measured weight is corrected according to the expected weight loss rate of the product, and the price is calculated based on this corrected weight.

In other words, the unit price is set and priced based on the weight after the change. By the way, as a method of pricing in the embodiment shown in FIG. 1, there is a concept of pricing based on the weight at the time of measurement.

In this case, since the weight of the product changes when it is sold, the price printed on the label does not match the weight x unit price at the time of sale. Therefore, the unit price should be corrected. In other words, the printed unit price is also the corrected unit price by dividing the price (the product of the set unit price and the net weight) by the corrected weight. In addition, the corrected unit price is 1 price.
−? The correct unit price is obtained by dividing the set unit price by the correction rate.

Further, the price is the product of the corrected weight and the corrected unit price, and by first calculating the corrected unit price, the circuit is simplified and the corrected weight, correction, unit price, and price can be obtained.

Therefore, in the embodiment of FIG. 2, a unit price correction section 21 is added to the circuit of the embodiment of FIG. 1, and the set unit price is divided by the correction rate to obtain a corrected unit price. This corrected unit price is input to the price calculating section 5, and the price is calculated as the product of the corrected weight value and printed on the label. In this case, the corrected weight, corrected unit price, and price as the product of each are printed on the label, and 1
Each value is displayed on two displays. In the first and second embodiments above, two correction methods were explained: one in which only the weight is corrected, and the other in which the unit price is corrected in addition to the weight. An embodiment in which the correction method can be switched will be described. The simplest example of this is to attach a changeover switch to the circuit of the embodiment shown in FIG. 2 and manually change the changeover.

Furthermore, a method of automatically switching in accordance with the value of the correction factor may be considered.

Assuming that the value of the correction factor is changed depending on the case where the correction factor is >1 or the correction factor is <l, when the correction factor is 1, the function of the embodiment in FIG. There are cases in which correction is performed using the function shown in the figure, and cases in which correction is performed using the function shown in FIG. 2 when the correction factor is 2 and 1, and the function shown in FIG. 1 when the correction factor is >1.

A circuit embodying this is shown in FIG.

This circuit is obtained by adding a changeover switch 31 and a determination circuit 32 to the circuit shown in FIG. This determination circuit 32 determines whether the correction factor is larger than l. Then, as the control signal a, the signal "1" is set when the signal is 1, and the signal "0" is set when the signal is 2. In this case, the determination circuit 32 is given the signal "l" as the control signal a. is input, if the correction factor is <1, the switching circuit 31 is connected to the V side by the output signal of the determination circuit 32, and the weight value is corrected, as in the case of the circuit in FIG. , the label will be printed.

When the correction factor>1, the switching circuit 31 is connected to the W side by the output signal of the determination circuit 32, and a label is printed as in the case of FIG. Note that the operating conditions of the switching circuit 31 can be set and set in various ways depending on the combination of the correction factor and the control signal a.

Next, a circuit configuration in which various functions are added by adding to the circuits described in FIGS. 1 to 3 above will be described.

In addition, in the following explanation, the same number indicates the same circuit as previously explained. The circuit shown in FIG. 4 is a circuit that switches between the function of correcting the weight value (or unit price) and the case where no correction is necessary, that is, the function of a normal electronic scale with a label printer.

In other words, when the switching circuit 41 is connected to the P side manually or by the control signal b, the corrected weight value becomes
Sent to each circuit. Therefore, each corrected data is printed and displayed. Next, when connected to the 0 side, the net weight from the weighing device 3 is sent to each circuit, so the operation is the same as that of a normal electronic scale with a label printer. Also,
The circuit shown in Fig. 5 reads the correction factor not only from the printer side (product name stamp) as explained earlier, but also by the unit price setting switch (numerical key number 1) on the electronic scale side.
This is a circuit that allows input.

When inputting the correction factor from the printer side, it can be input manually or by using the control signal C. d connects the switching circuit 51 to the Q side and the switching circuit 52 to the S side. Therefore, the correction factor read by the correction factor reading section 1 is sent to the weight correction section 2, etc., and the unit price set by the unit price setting section 6 is sent to the price calculation section 5, etc. Next, if you want to input the correction factor from the electronic scale using the numeric keypad, you can input it manually or by using the control signal C. By d, the switching circuit 52 is connected to the S side and the switching circuit 51 is connected to the R side, and the unit price is set in a numerical value. The set unit price is determined by the switching circuit 52.
The data is sent to each circuit, such as a price calculation unit, and stored therein. Next, only the switching circuit 52 is connected to the T side, and the correction factor is set using the numeric keypad. The correction factor is sent to each circuit such as the weight value correction section 2 via the switching circuits 52 and 51. Therefore, the correction factor was input from the numeric keypad. Next, as shown in Fig. 6, the correction factor is stored in the electronic scale with a printer, and read out by inputting a code (symbol) etc. corresponding to the product name from the outside. This is what I did.

In this case, there is no need to provide special data to the printer. That is, the product name code reading section 61 reads each product code used for normal products and sends it to the reading device 62, and the necessary correction factor is read from the correction factor storage device 63, and the weight value is corrected. The signal is sent to each circuit such as section 2, and necessary corrections are made. In addition, Figures 4 to 6
The additional circuits shown can be added singly or in combination to the apparatus of FIGS. 1-3.

As explained above, in the case of an indefinite quantity of packaged products whose weight changes between the time of measurement and the time of sale, the present invention corrects the weight value at the time of measurement to adapt to the weight at the time of sale.
Since a device for printing and issuing a label to be attached to a packaged product is provided, even if the product naturally loses weight, it will not make consumers feel distrustful, and there will be no need to take measures such as marking.

In addition, we have made it possible to set the weight ratio (natural decrease rate or increase rate) from either the product name stamp on the label printer or the number pad installed on the electronic scale, and we have provided various additional circuits. The device becomes easy to handle.
