DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring and valuing apparatus for weighing merchandise such as meat, fresh fish, vegetables and the like and calculating the price of the merchandise from the weight and unit price of the merchandise.

[0002]

2. Description of the Related Art A plurality of unit prices (for example, a normal unit price and a discount unit price) are stored in one product number (product number), and one of the plurality of unit prices is selected and used when performing a pricing operation. A weighing and pricing apparatus configured as described above has been developed (Japanese Patent Publication No. 1-45566). In this case, one of the criteria for selecting the unit price is the quantity of the product. For example, when the quantity of the product is equal to or more than a predetermined value, the unit price of price quote is selected as a discount (the higher the purchase amount of the same product, the lower the price, the higher the sales promotion effect).

[0003]

However, in the above-mentioned method, since the unit price is selected by the operation of the operator,
In addition to troublesome work, there is a risk that a pricing mistake due to an operation mistake may occur. In order to solve this drawback, it has been considered and practiced to automatically select the unit price based on the weight of the weighed product (Japanese Patent Laid-Open No. 4-164215). However, this method has the following problems.

[0004] The product weight (usually three digits or more), which serves as a reference for selection, must be stored in advance for each product number, so that the setting operation is troublesome and there is a possibility that a setting error may occur due to a setting error. . Even if the size of the tray for storing the products is the same, products with different unit prices may be mixed, and it may be difficult to distinguish products with different unit prices. Before and after the switching weight value, the magnitude of the weight of the product and the magnitude of the price may be reversed.

[0005] This proposal has been made in view of the above circumstances, and aims at solving the above-mentioned problems. It has been proposed that the unit price of a product is automatically selected depending on the tray to be used. A weighing and pricing device is provided.

Next, an outline of the operation of this embodiment will be described with reference to FIGS.
This will be described with reference to FIG. 2 and a flowchart of the operation.
FIG. 3 is a flowchart of the operation of the packaging machine unit B. In this figure, the processing routine of the packaging machine section B is started by placing the product 3 at a predetermined position on the carry-in conveyor 2. Hereinafter, the operation will be described in order from step SP10 (hereinafter, referred to as SP10 and the like).

First, at SP10, the loading conveyor 2
Before the product 3 is loaded into the packaging machine 1
1. Each size of the length (L), width (W) and height (H) of the product 3 is detected by the sensor s2 and the sensor s3. SP11: The L and W data among the detected sizes are sent to the weighing section A.

SP12: The control data of the packaging machine is determined based on the detected sizes L, W and H of the product 3 and the tray type T. The control data includes the film cut length, the amount of film pre-stretch, the position at which the product 3 is loaded onto the elevator head, the operation timing of the folding plate, and the like. SP13: Each operation unit is controlled based on the control data determined in SP12 described above to perform a packaging operation. SP14: The packed product 3 is carried out to the carry-out conveyor 4.

FIG. 4 is a flowchart for explaining the operation of the weighing section A. The operation of the weighing section A will be described with reference to FIG. SP21: Enter the product number (product number) of the product to be weighed and priced. The input of the product number is performed before the product is supplied to the packaging machine. When a product number is input, data of the product number stored in the product file (PLU file) is read out and stored in each register of the RAM 12. The product file in the RAM 12 stores data as shown in Table 1.

[Table 1]

Here, the unit price is a normal unit price, and the unit price is a service unit price for a mass purchaser. Is a tray number serving as a unit price switching reference. In this embodiment, the unit price is set for the trays with the tray numbers higher than this tray number,
If the number is less than the tray number, the unit price is used. In addition,
In this embodiment, a tray number is assigned so that the size (large or small) of the tray can be determined from the tray number. For example, TA1 <TA2 <... <TAn, and the A-type tray No. 1 TA1 is the A-type tray 2
It is smaller than TA2.

SP22: The tray number (type is determined from the size L and W of the product (tray).
This is performed based on the tray size (L, W) -tray number conversion table stored in the AM 12. RAM12
Table 2 stores data in the tray size (L, W) -tray number conversion table.

[Table 2]

SP23... The unit price U is selected based on the tray number determined in SP22 and the switching reference tray number called from the product file. For example, the switching reference tray number TNo. = 3, if the tray number TN determined in SP22 is 3 or more, the unit price
When N is 2 or less, the unit price is set.

SP24... Tare weight WF (tray weight or tray weight + film weight) is determined based on the tray number determined in SP22. This determination is made based on the conversion table. SP25: Measures the total weight WG including the tray weight of the product on the weighing conveyor.

SP26: The price P of the product is calculated from the total weight WG, the tare weight WF and the unit price U by the following formula. WN (net weight) = WG-WF P = (WN × U) / 100 (The fractional part is truncated. Since the unit price U is a price per 100 g, divide by 100.)

SP27: The product name, weight, unit price, price, effective date, etc. are printed on a label. SP28: The label is automatically attached to the product. This embodiment relates to processing in a case where a tray number is automatically detected, a tare weight is automatically set, and a switching reference tray number is stored in a product file.

Next, another embodiment according to the present invention will be described. This embodiment does not include a tray number automatic detection function. When inputting a product number, the user inputs a tray number of a tray to be used by a key. Also, a tray number used for each unit price may be stored.

[Table 3] For example, as shown in Table 3, the product of product number 1234 is an example in which tray numbers other than tray numbers 2 and 4 are not used.

[0032]

[Table 4] Further, as shown in Table 4, the product with the product number 1234 has two types of unit prices, whereas the example has five types of trays of 1, 2, 3, 4, and 5. In this case, the tare weight is also determined by the tray number, but may be set separately from the tray number. For example, a tare weight is input by key when inputting a product number. Alternatively, as the tare weight, the weight of the maximum size tray to be used is stored for each product, and is called and used when a product number is input. In this case, if the tray to be used is not the maximum size tray, the tare weight will be heavier than the actual tare weight, and this branch will lose, but the customer will not lose, so it will not be an illegal transaction. .

The operation of one embodiment of the present invention has been described above in detail with reference to the drawings. However, the present invention is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. The present invention is also included in the present invention. For example, the following cases are also included in the present invention. Not all products may store multiple unit prices. It is conceivable to store three or more types of unit prices and select one of them. Manual mode for selecting unit price data by key operation,
A configuration is also conceivable in which a weight mode performed by weight value and a tray type mode performed by tray type can be selected.

In the embodiment, there was a case of a packaging / weighing / pricing device. However, the present invention is not limited to this, and a weighing / packaging / pricing device, a weighing / pricing device or the like may be used. The configuration of the sensor (detection means) is not limited to that of the embodiment, and the tray type may be detected by pattern identification processing using, for example, a TV camera. When the unit price is switched from the normal unit price to the unit price for the service, an indication to that effect is automatically printed on the label, and two types of label printing and pasting devices are prepared, and the label used according to the selected unit price It is also conceivable to select a printing and pasting device and perform different printing.

[0035]

As described above, according to the present invention, the following effects (a) to (e) can be obtained. B) Since the unit price is automatically selected based on the tray size (type) for storing the product, the unit price can be selected without mistake compared to when the operator selects the unit price by key operation. And it can be done easily.

B. Tray size (type) for storing products
We automatically select your bid based on your
The unit price is not suddenly changed during weighing as compared with a case where the unit price is automatically selected according to the weight of the weighed weight. Further, as compared with the case where a weight value serving as a reference for change is set in advance, setting of tray size (kind) data of a limited kind is simpler and setting errors are reduced.

C. Tray size (type) for storing goods
We automatically select your bid based on your
Compared to the case where the unit price is automatically selected based on the weighed weight, there is no case where products with the same size of trays to store products and different unit prices are mixed, and products with different unit prices are distinguished. Becomes clear. Further, there is no problem that the magnitude of the weight of the product and the magnitude of the price are reversed before and after the switching weight value.

(4) The unit price is automatically selected based on the detection result of the tray size detecting means. There is no danger that the unit type does not match the input tray type and correct unit price data is not selected.

E. Since it is desired that the tare weight can be automatically set based on the detection means of the tray size specification means or the specification or detection result of the detection means, the tare weight is manually set according to the tray to be used. No need.
