Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a label printer used in conjunction with a weighing device.

Conventionally, some of the above-mentioned label printers are disclosed in, for example, Japanese Patent Laid-Open No. 131147/1983. This involves intermittently transporting the label each time printing is completed, and printing a first printed item indicating the weight value or a value that changes according to the weight value on the same label that has multiple lines of printing fields, and a weight value. In a label printer that prints a second print item that indicates a constant value regardless of the value, it is determined whether or not the object to be weighed is loaded on the load conversion section that outputs the weight value, and the object to be weighed is When it detects that a load is applied to the load conversion unit, it instructs to start printing the line containing only the second printing item,
A printing operation control unit is provided which instructs to start printing the line including the first printing item when it is detected that the printing operation of the second printing item is completed and the weight value has reached a balanced state. be.

However, with this label printer, the instruction to start printing the second print item row is given by detecting that the object to be weighed is loaded on the load converter, so printing is performed on one label. After this is completed, in order to start printing the second item on the next label, remove the article loaded on the load converter,
It was necessary to once return the output of the load converter to 0 and then load the next article. Generally, it takes about 0.6 seconds to remove the article loaded on the load converter and return the output of the load converter to zero.
In addition, it takes about 0.6 seconds to load a new article to the load converter whose output has returned to 0 and until the output stabilizes (during which time the second printing item is printed). , it takes about 0.2 seconds to print the line containing the first print item after stabilization. Furthermore, it takes approximately 0.2 seconds to feed and issue the label. Therefore, there was a problem in that it took approximately 1.6 seconds from the end of printing on one label until the end of printing on the next label.

This idea solves the above problems,
The label detector detects that the label on which all printing has already been completed is peeled off, and starts printing the second printing item.

According to this, when the printed label is peeled off, printing of the second printing item will start on the next label even if the object to be weighed that was weighed earlier is placed on the platform. When loading the next object to be weighed onto the load conversion section, there is no need to wait until the output of the load conversion section returns to 0 before loading the object to be weighed, and printing can be performed with high efficiency.

Hereinafter, this invention will be explained in detail based on one embodiment shown in the drawings. In FIG. 2, reference numeral 4 denotes a label printer body of this invention which is integrated with a weighing device, and is used to issue labels as shown in FIG. 1. A table surface 6 of the weighing device section 5 of the label printer main body 4 is provided with a tray 7 for placing products thereon. The front surface of the label printer main body 4 is provided with a product name setting instruction section 8, a numeric keypad input section 9 for setting and inputting unit prices, etc., a display section 10 for unit prices, weights, prices, etc., a label issuing port 11, and the like.

FIG. 3 shows the inside of the label printer main body 4 in the form of a block and a perspective view. Inside the main body, a long paper 13 is supplied with pre-printed labels 12, 12, . . . pasted at equal intervals. It is supported by a roller and a take-up roller (both not shown). During the movement path of the mount 13, the mount 1

is rotated in the direction of arrow C, and the mount 13 is transferred in the direction of arrow D. A dot printer 17 is attached to a guide pin 26 supported by a frame (not shown) of the main body.
is supported movably in the direction of arrow A-B, and a printing ribbon 18 is placed in front of the dot printer 17.
is provided. It is also composed of, for example, a light source 25 and a light-receiving element 27, which are mostly peeled off by the peeling plate 14, are very slightly adhered to the mount 13, and are arranged to face each other with the label 12' protruding forward from the issuing port 11 in between. A label peel detector 29 is provided.

In the above-mentioned label printer, a key in the product name setting section 8 is pressed to specify the product name. After that, when the label 12' on which printing has been completed is completely peeled off from the mount 13 and taken out from the light emitting port 11, a pass signal is supplied from the light receiving element 27 to the printer control unit 23, and the printer control unit 23 issues a print command. A signal is transmitted to cause the dot printer 17 to start printing. The dot printer 17 prints the product name specified by the product name setting section 8 on the label 12 while moving in the direction of the arrow AB. When printing of the product name is completed, the printer control unit 23 supplies a drive signal to the motor 19, rotates the feed roller 15 in the direction of arrow C, transports the mount, and moves the label 12 to the position where the unit price, price, etc. are printed. and stop the motor 19.

During this time, after a new object to be weighed is placed on the tray 7, the previous object to be weighed is removed, and the weighing section 20 is stable. At this time, the weight detecting section 21 converts the displacement of the measuring section according to the weight of the object to be measured into an electrical signal, and the calculating section 22 performs calculation to calculate the price from the weight and unit price. The calculation results are displayed on the display section 10 and sent to the printer control section 23 at the same time. The printer control section 23 sends a print command signal to the dot printer 17. Dot printer 17 is indicated by arrow A
- While moving in the direction B, print data as shown by reference numeral 3 in FIG.
The motor 19 is driven by the drive signal from 3 to rotate the feed roller 15 in the direction of arrow C, the mount 13 is moved in the direction of arrow D, and most of the printed label is peeled off from the mount by the peeling plate 14. It is made to protrude forward from the issuing port 11 in a state where it is very slightly adhered to the mount 13. Further, by moving the mount 13, the next label is sent to the position where the product name is printed, and when the printed label is completely peeled off from the mount 13, printing of the product name is started again.

A series of operations in this embodiment is shown in the flowchart of FIG. The operation of the entire device starts at F1, and the product name is set at F2. The unit price is set and input in F3, and label 1 is printed first in F4.
It is detected whether the label 2' has passed through the label detector 29, that is, whether it has been completely peeled off from the mount 13. If the label 12' has passed, the product name is printed on the next label at F5. If the label 12' does not pass the label detector 29, the product name is printed at F5 after waiting for the label 12' to pass through the label detector 29. At F6, the label 12 is sent to the position where weight, price, etc. are printed. A new object to be weighed is placed on the tray 7 in parallel with these steps F5 and F5, and the previous object to be weighed is removed. Immediately after the measuring section becomes stable at F7, the price calculation is performed by the calculating section 22 at F8. If the weighing section 20 becomes stable when the label feeding at F6 is completed, the calculation at F8 is immediately performed. Weight, unit price, and calculated price are F9
The label is printed on the label 12 at F10, the label is fed and the printing completed label is issued, and if there is no change in the product name at F11, the process immediately returns to F4.
If there is a change, return to F2.

As described above, according to this invention, the label detector 2 detects the peeling off of the label 12' that has been printed first.
9 is detected, printing of the product name on the next label 12 is started. Therefore, printing of the product name on the next label will not start unless the object to be weighed corresponding to the previous label is removed from the tray, the output of the weight detection section is returned to 0, and a new object to be weighed is placed. Compared to conventional methods, even if you place the next item on the weighing pan with the previous item still on the weighing pan, the product name can be printed on the next label as long as the previous label is peeled off. Begins. Then, the product name is printed on the next label, and while the label is being fed, the previous item to be weighed is removed from the weighing pan, and the output of the weight detection section is set, and the price is immediately calculated, and the weight and unit price are calculated. and the price are printed on the label, and the label is sent. Therefore, it can print labels faster than conventional label printers, and is especially effective when printing labels by continuously weighing tens to hundreds of identical items with the same unit price. .
