Abstract

PURPOSE:To improve the operability of weighing operation by recording tare information in bar code, etc., on a tare container, reading this information by a reading means provided to a pan, and subtracting the tare value obtained from the tare information from a weighed value. CONSTITUTION:A window part 15 is provided to the counter pan of a weighing device and a bar code reader 16 is fitted in this window part 15. The bar code indicating the tare information for discriminating the tare container is printed on the bottom surface of the tare container 8. This tare information is read by said bar code reader 16 and the tare information is supplied to a read part 3. The read part 3 reads the tare value of a read number specified by the tare information out of a memory 1 and supplies the tare value to a tare erasure part 4. The tare erasure part 4 subtracts said tare value from the weighed value inputted through a load cell 5 and an A/D converter 6 to calculate the net weight value.

2. Description of the Related Art There are three types of conventional machining devices as shown below. The first method is to place only the tare container on the weighing plate of the electronic scale (hereinafter referred to as the plate), then load the total value into the memory and store it in the memory. Subtract the current weight value from the current weight value to get the net type m#! The second is "one-touch tare subtraction", which sets a known tare value using the numeric keypad each time the WA bag container is replaced, and subtracts the set tare value from the occasional weighing value to obtain a net balance. ``Weight setting WA bag pull'' and the third one is to record multiple frequently used tare values in advance in the memo IJ-.
Key in the readout number of one of the multiple tare values written in the memory and read it out, and subtract this readout tare value from the occasional weighing value to obtain the net weight [readout number setting tare subtraction] It is.

The first [one-touch tare subtraction] mentioned above is an in-process operation because it only gives a filling instruction to the memory.
If a total of two weighing operations are required, in which only the tare container is weighed, then the object to be weighed is placed in the tare container and weighed, and the object to be weighed is already placed in the tare container, Unless the tare weight can be set in advance, the net weight cannot be determined, such as the 1 weight II setting waste bag subtraction mentioned in the second and third sections or the reading number setting tare subtraction.

FIG. 5 shows a conventional electronic fare scale that employs "readout number setting tare subtraction". The memory 1 stores the tare value of each tare container for each readout number, and when you key in the readout number corresponding to the tare container to be used on the numeric keypad 2, the readout section 3 reads out the keyed-in readout from the memory 1. The tare value corresponding to the number is read and supplied to the tare eraser 4 as a subtracted value. The tare eraser 4 is supplied with the occasional weight value obtained by digitally converting the output value of the load cell 5 by the AD converter 6 as the minuend.
1 ml of the π1 hanging object 9 placed in the tare container 8 on top
! When placed on the output side of the tare eraser 4, the maximum net weight value of only the object to be weighed 9 is obtained. The net Φ hanging is compared with the price per unit III set in the unit price setting section 11 in the calculation section 10 to determine the price of the object 9, and the price is digitally displayed in the price display section 12. Ru. 13 is a weight a display section that digitally displays the net weight, and 14 is a unit price display section that digitally displays the unit price.

Problems to be Solved by the Invention In such a conventional configuration, each time the tare container is replaced, the operator is required to key in the readout number "It" for a new tare container using the numeric keypad 2. In this case, another tare value is read from the memory 1, and the tare eraser 4 performs an incorrect tare subtraction, making the price appearing on the price display 12 unreliable.

According to this configuration, if the tare information is recorded on the contact surface of the tare container with the weighing plate, then simply by placing the tare container on the weighing plate, the reading means will read the tare information from the tare container. Based on this, the tare subtraction means erases the tare.

On the back side of each tare container 8, as shown in FIG.
Tare information representing 80 types of tare containers is recorded in advance with a barcode 17 at a position corresponding to about 2 windows 15 of f17, and the barcode 7 of the WA bag container 8 placed on the placing plate 7 is recorded in advance. When read by the reader 16, the tare information is supplied to the reading section 3, and the reading section 3 reads out the tare 1 of the readout number designated by the tare information from the memory 1 and supplies it to the tare erasing section 4.

In the first embodiment, an optical barcode reader 16 was used as the reading means, but this is [! When characters, figures, etc. corresponding to the type of tare container 8 are recorded as loading information on the container 58 instead of the barcode 17, an image sensor is used as the reading means to record the read characters, figures, etc. It is configured to read out the necessary tare value from the memory 1 based on this determination. Also, F as tare information! When the A bag container 8 is colored according to the type, the reading means uses a color sensor to determine the read color, and based on this, the necessary tare value is read out from the memory 1. be done.

In the first embodiment, a memory 1 into which a plurality of tare values have been read and a barcode reader 16 as a reading means is used.
The memory 1 to 1 according to the tare information detected in
A readout unit 3 reads out the tare value, and the jI1 bag value read out by the readout unit 3 is subtracted from the weight value to obtain a net value of 1.
Although the tare subtracting means 18 is configured with the tare erasing section 4 for setting a lower value, this does not mean that the content of the tare information recorded in the tare container 8 represents the type of the tare container 8, but the individual tare value. In this case, the same effect can be obtained by configuring the tare value detected by the barcode reader 16 to be supplied to the tare erasing section 4 as in the second embodiment shown in FIG.

In the first and second embodiments, the reading means is an optical head such as an optical barcode reader 16, an image sensor, or a color sensor. When the tare information is recorded on magnetic ink or a magnetic recording medium and added to the tare container 8, the reading means is constituted by a magnetic head.

Effects of the Invention As described above, in the tare subtraction device of the present invention, the reading means detects tare information from the tare container placed on the weighing tray of the electronic scale, and the tare subtraction means detects the tare information from the tare container placed on the weighing tray of the electronic scale. In order to obtain a net single value by subtracting the tare value from the corrected Φ value based on the tare information, the tare container in which the object to be weighed or the tare container before the object to be weighed is placed in the weighing pan. It is possible to tare the weight just by placing it on the scale, and there is no need to perform the F@ device setting operation at all, which was conventionally done on a work day when taring the weight in advance.This greatly improves the operability of electronic scales. This is something that can be improved.
