Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic scale with a label printer.

For example, when weighing an item transported by a conveyor, printing various data such as unit price, weight, price, etc. on a label, and attaching the label to the item, it is natural that if the item changes, the unit price etc. Data changes. Furthermore, when items are conveyed by a conveyor, the width of the tray changes as the items change, and accordingly the width of the guide that corrects the flow direction of the items also changes. Also, if the product changes, the effective date will change even if the processing date remains the same. The validity period varies depending on the item, for example, 5 days or 10 days, so each time the item to be weighed changes, the operator must calculate mentally or by hand based on the processing date and the validity period of the item. It is necessary to calculate the effective date and set the calculated effective date. In this way, when the item changes, various data change, and it is necessary to reset the data to correspond to the new item before printing the data on the label. If this data is set every time the item changes, work efficiency will be greatly reduced.

Therefore, with the present invention, if you set the processing date and set the unit price, shelf life, and tray width of various items once in advance, even if the item to be weighed changes, you can automatically weigh it by simply inputting the product name code of that item. The corresponding unit price, validity period, and tray width are read out, and the validity date is automatically calculated from the read validity period and the set processing date and sent to a printer, etc., and the read unit price is displayed on the display unit, printer, etc. At the same time,
To provide an electronic scale that improves workability by sending an adjustment command to a tray width adjustment means corresponding to the product name code. Hereinafter, the present invention will be explained with reference to the drawings.

The present invention stores product name codes manually (in the case of the first embodiment) or by manual or automatic means (in the case of the second embodiment) in a storage unit that stores data such as unit prices of products by product name code. An example of the circuit is shown in FIG. 1, which reads out the data stored in the storage section by inputting the following information and sends it to the display section, printer, etc. This figure 1 shows automatic weighing of items transported by a conveyor.
The present invention is applied to a fully automatic label printer that calculates the price from a preset unit price and measured weight, prints data such as unit price, weight, price, etc. on a label, and then automatically attaches the same label to the item. In this circuit example, 1 is a storage section, 2 is a manual input section, and 3 is an automatic input section. If a microcomputer is used as an example, the storage unit 1 includes an input control unit 4, a CRU (central processing unit) 5, a ROM (ROM, read-only memory) 6, and a RAM (random access memory), as shown in the figure. memory) 7, and output control section 8
The RAM 7 is powered by a battery 9. The first embodiment of the present invention does not have an automatic input section 3 and inputs data and product name codes only using the manual input section 2.The second embodiment has an automatic input section 3 in the manual input section 2. The second embodiment will be explained below for the sake of simplicity. Furthermore, the first
In the figure, 10 is a weight detection part, 11 is a number display part for processing date, tray width, etc., 12 is a display part for unit price, weight, price, etc., 13 is a printer, 14 is a label pasting machine, and 15 is on a conveyor. 16 is a conveyor drive unit.

The second embodiment will now be explained with reference to the following operations (a) to (d), such as automatic data setting and manual data setting. That is, (a), when the product name stamp is attached to the label printer, the unit price etc. are automatically read out from the storage unit 1. (b) Attach the product name stamp to the storage unit 1.
The act of writing (memorizing) data such as unit prices into. (c) Enter the product name code from the manual input section 2 into the storage section 1.
An operation in which the unit price, etc. is automatically read out.
(d) Operation of inputting the product name code into the storage unit 1 from the manual input unit 2 and writing data such as unit price into the storage unit 1. In (a) and (b), the product name stamp is used, and in (c) and (d), the product name stamp is not used.

In the case of operation (a) above, when the product name stamp is first attached to the printer, subprogram SUB1 (see Figure 4) in ROM6 of storage unit 1 is called.
The fact that the product name stamp has been installed is indicated by lighting a lamp, etc. Then, the storage unit 1 stores the product name stamp number from the product name stamp, that is, the serial number (0, 1,
2, 3, etc.) is read (detected) and the number is converted into the address of the registered data and product name code (see Figure 3). This registration data is data such as unit price, tare weight, weight, etc. for each product name stored in the registration data area. For example, if the product name is "Beef Loin" and the product name stamp number is "2", it is "Beef Loin".
Address “1002” where the unit price etc. of
It is converted to the address "4002" where the product name code is stored. The product name stamp number is detected by means such as a photoelectric method that uses light to read the number of holes provided in the product name print, or by using a magnetic tape.

Next, the address of the converted registration data (“1002”
etc.), data (unit price 800 yen, etc.) is registered (memory) in advance.
Check whether it is set or not. This check is performed depending on whether the content of the registration flag is "1" or "0"; if it is "1", it is determined that it is registered; if it is "0", it is determined that it is not registered; if it is "0", the program returns to the main program. Also, if the data is registered as "1", then the quantitative flag will determine whether it is a fixed quantity product (item whose weight or price is constant and is not measured) or an indefinite quantity product (item whose weight or price is determined by weighing). It is checked as “1” or “0”. The checked results are displayed using lamps or the like.

Further, the registered data of the address ("1002", "4002", etc.) converted from the product name stamp number and the product name code are transferred to the working area, and first, changes in the tray width are checked. In other words, it is checked whether the tray width is the same as the tray width corresponding to the product name stamp installed previously, and only if it has changed, the width of the guide on the conveyor is controlled according to the tray width at that time. Ru. Then, the effective date (already transferred to the working area) is added to the processing date to calculate the effective date. However, the processing date is
Manual settings are made every day using the numeric keypad and processing date setting key as shown in FIG. The data (unit price, etc.) transferred to the working area is then displayed on the display section 12.

Also, when monitoring the number of products produced by store, etc.
After displaying the registration data mentioned above, it is checked whether an external computer (such as a large-scale computer at the main store) is connected. When connected, the storage unit 1 outputs the product name code to an external computer, and inputs the number of products produced by each store, etc. corresponding to the product name code from the external computer. Also, if it is not connected, manually set the production quantity etc. for each store. To make this setting, refer to Figure 2. key (ON), enter the next store code using the numeric keypad, repeat the above steps, and set the number of items for each store. Once the settings are complete (turn off the number registration switch) Make it. Once the settings are complete, a series of operations such as weighing, printing, and labeling begin. When the set number of items has been weighed, the worker is notified that the number of items produced has reached the set number and starts weighing. etc. will stop.

Next, when the set number of measurements, etc. is completed and the product name stamp is removed from the printer, the subprogram SUB2 shown in FIG. 4 is called, and first, it is displayed that the product name stamp has been removed. Then, it is checked whether data is registered in the address of the registration data area corresponding to the product name stamp number of the removed product name stamp. Since it is registered, the data stored in the working area is transferred to the address (such as "1002") and restored, and the program returns to the main program. If it is not registered, a check is made to see if data such as unit price was entered using the numeric keypad while the product name stamp was attached. If no number is set at all, data transfer is not executed and the program returns to the main program. In other words, this is to prevent malfunctions. For example, when the product name stamp for "beef loin" is removed, i.e., the unit price of beef loin remains in the working area, the product name stamp with no data registered is removed. If you attach it to the printer and remove it without setting any data,
The data in the working area (beef loin data) is not transferred to the address in the registration data area that corresponds to the registered product name stamp mentioned above, and therefore there may be mistakes such as data being registered even though the number has not been set. doesn't happen.

The above is the operation (a), and it can be seen that when the product name stamp is attached to the printer, data such as unit price and tare weight are automatically read out from the storage unit 1, displayed, and printed on the label, etc. Next, the operation (b) of attaching the product name stamp and writing data to the storage unit 1 will be explained.

First, attach the product name stamp. Then, if data is registered before wearing, the data is transferred to the working area and displayed on the display section 12. Also, if the data is not registered before installation, display section 1
2 is a zero display or blank.

Next, set the unit price and other data. That is, first enter the unit price using the numeric keypad. This entered unit price is stored in the working area and displayed on the entered number display section 11. Note that the number display section 11 displays the processing date until the unit price is entered. Then, when the unit price setting key is turned on, the unit price is displayed on the display section 12, and the number display section 11 displays the processing date again. After that, even if you repeat the same operation as above,
Set the necessary data such as tare weight in sequence. Finally, when the product name stamp is removed, each data stored in the working area is transferred to the registered data area.

In this way, when the product name stamp is removed, data such as the unit price is transferred to and stored in the registered data area, so even if the unit price is changed several times, the last set price will be stored in the registered data area. be done. Incidentally, when changing and setting only a part of the already stored data, for example, the tray width, it is sufficient to set only the tray width.

Until now, data has been read and written using the product name mark, but next we will explain the operation when the product name mark is not used.

In other words, in the case of operation (c), in which the product name code is input into the storage unit 1 from the manual input unit 2 and the data is automatically read out, first turn on the product name stamp switch.
do. This will make it the same as when the product name stamp is attached. Then enter the product name code using the numeric keypad,
Turn on the product name code key. When the product name code is set, the storage unit 1 detects the address where the set product name code is stored, and from the same address, the address (registered data area) where the unit price etc. of the product name is stored. Calculate. Then the rest
It operates in the same manner as in (a), and data is read. Then, when all measurements, etc. are completed, turn off the product name stamp switch. This OFF is equivalent to removing the product name stamp. This operation (c) is necessary when the product name stamp is lost or to automatically read data even if the product name stamp is not attached. In this case, the product name is not printed on the label.

Next, write the data to storage unit 1 without the product name stamp.
To explain the operation of (d), first press the item registration switch.
Turn on. At this time, the product name stamp may still be attached.
Then, enter the product name code using the numeric keypad and turn on the product name code key. Then, the storage unit 1 detects the address where the entered product name code is stored, and calculates the address of the registered data area corresponding to the product name. Next, when necessary data is set using the numeric keypad and setting key, the data is directly stored in the registered data area. Then, when the settings are complete, turn off the item registration switch.
Then, the display section 12 will show that the item registration switch is
Returns to the state before it was turned on. For example, if the product name stamp for "beef loin" is attached, the unit price of beef loin, etc. will be displayed again.

The operations (a) to (d) have been described above.Next, among the keys shown in FIG. 2, those not explained above will be explained one by one.

First, the clear key is a key switch for clearing the numbers entered on the numeric keypad. In addition, the variable quantity key is a switch for switching from a fixed quantity item to an indefinite quantity item.When turned on, the fixed quantity flag becomes "0" and the memory of the fixed weight, fixed price, etc. is automatically cleared. The display will be zero, making it possible to measure items of unknown quantity and print labels. Note that a key for switching from indefinite amount to fixed amount is not required. That is, when a fixed weight or a fixed price is set, the storage unit 1 sets the quantitative flag to "1". In addition, the return key is pressed when data other than the processing date is displayed on the numeric display section 11.
When turned on, the processing date will be displayed. This numeral display section 11 displays numeral data other than the processing date or display section 12.
When data that is not displayed (tray width, etc.) or an error occurs, an error number indicating the type of error is displayed. For example, if there is an overflow in the number of digits in the unit price or a numbering error in the year, month, and day without printing (such as 13th or 32nd), the value is "1", and if there is a printing error, the value is "2".
etc. will be displayed.

Also, in Figure 3, the 1000s and 2000s, and
Addresses in the 3000s are RAM7 addresses, and addresses in the 4000s and 5000s are ROM6 addresses. Note that since the RAM 7 is supplied with power by the battery 9, its stored contents are retained even if the power to the storage unit 1 is turned off or there is a power outage.

In the above embodiment, the product name code is fixedly stored in the ROM 6, but it may also be stored in the registration data area (RAM) together with the unit price, tare weight, etc. In this way, there is no need to convert the registered data address to the product name code address, and the product name code can also be changed.

Furthermore, if the product name code is stored directly on the product name mark, there is no need to store the product name code in advance in the ROM 6 or RAM (registered data area).

Furthermore, if the product name code is stored in the product name mark and the code is made the same as the address of the registered data area, there is no need to store the product name code in advance or convert the address from the product name code. For example, the product name code for "beef loin" is stored as "1002" in the product name stamp, and the unit price of beef loin, etc. is stored in the address "1002". This method is the most program and memory efficient.

In FIG. 3, all data such as the unit price of one item is stored in one address, but in case of overflow, the data may be divided and stored in two or more addresses. The above is a description of the second embodiment having automatic and manual input sections. The second embodiment does not have an automatic input section.
This is an example. Therefore, in the first embodiment, it is not possible to read or write data using the product name mark (operations (a) and (b) of the second embodiment), but other operations are the same as in the second embodiment. It is exactly the same.
As explained above, according to the present invention, if the unit price, expiration period, and tray width of each item are set in advance in the storage unit for each item code, even if the item to be weighed changes, the item name code of the item can be changed. Just by inputting this, the effective date of the item is automatically calculated and sent to a printer, etc., the unit price of the item is read out and sent to the display unit/printer, etc., and the tray width corresponding to the item is automatically calculated. Because it can be automatically adjusted,
This improves work efficiency by eliminating the need for the operator to calculate and reset the effective date, reset the unit price, and reset the tray width each time the items to be weighed change. can be achieved.
