Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label printer, and particularly to a label printer that is most suitable for application to a billing scale.

For example, the labels used in label printers for billing scales are printed with characters such as "date of processing,""per 100g (yen),""net amount (g)," and "price (yen)." A label roll obtained by pasting a large number of such labels at equal intervals onto a strip-shaped backing paper with adhesive and rolling it up is set in a label printer, and when printing a label, the printer section corresponds to the above characters. Data is printed, and the printed label is peeled off from the mount at the peeling section. After peeling off, the mount is wound up by a winding device. However, the current situation is that this mount is not used for anything and is just thrown away. This is very wasteful since the backing of the label rope uses a relatively expensive paper such as paraffin paper to facilitate label peeling.

The present invention has been made in view of the above points, and an object of the present invention is to provide a label printer that enables more economical use of label rolls. According to the present invention, this object is achieved in a label printer, which includes a printer, a label peeling means, and a label tape winding drive means, in order from the side that supplies the label tape with the label pasted on the backing paper, the label peeling means has the label tape. A label tape drive means is provided on the tape supply side to drive the label tape in the direction of supplying the label tape to the label peeling means side by switching or in the opposite direction, and a label peeling means is provided, and the label peeling detection means is provided. The label tape is rewound in the opposite direction by a predetermined pitch by switching the label tape drive means in response to the output of the label tape, and the printer prints predetermined data on the mount. This is achieved by a label printer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be described with reference to the drawings regarding an embodiment in which the present invention is applied to a toll scale with a label printer.

FIG. 1 is a perspective view showing an overview of a toll scale with a label printer to which this embodiment is applied. In the figure, a label roll 1 is set on the upper surface of a casing 2. A weighing plate 3 and a winding part cover 4 are provided on the front horizontal part of the casing 2.
An operation panel 5 equipped with a numeric keypad switch and a display section, and a printer cover 6 equipped with a label issuing port 7 are provided on the front vertical portion.

The label roll 1 is made by winding a label tape T consisting of a large number of labels L affixed at equal intervals with an adhesive onto a strip-shaped mount 20. As shown in the figure, it is guided and finally wound up by a winding device.

FIG. 2 is a side view schematically showing the label printer section of the toll scale with label printer according to the embodiment of the present invention.
The situation is shown immediately after the label tape T is fed out and filled into the machine.

Next, the configuration of the label printer section will be explained in accordance with this filling operation.

First, the label tape T is unwound from the newly set label roll 1 and inserted into the label supply port guide 9 formed on the upper surface of the casing 2. Next, it is guided to a drive device 30 according to the invention, which drive roller 31
The drive roller 31 is rotatable in both forward and reverse directions, and the pressure roller 32 is pressed against the drive roller 31 by a spring action, but is separated from the drive roller 31 against this spring action. In other words, it is configured to be able to be released.
In such a drive device 30, the drive roller 3
1 rotates clockwise, that is, in the positive direction, as shown by the arrow when filling the label tape, and the label tape T is clamped and pressed by the drive roller 31 and the pressure roller 32, and is transferred to the next guide section 10. be guided. The guide section 10 includes a holding device 21, which normally presses the label tape T against the guide surface by a spring action, but is configured to be releasable. When filling the label tape T, the pressing device 21 is released and the label tape T is passed through the guide portion 10. Hereinafter, the label tape T is moved toward the peeling table 14 by the stop position detection device 1 disposed along its running path.
1, printer internal guide 13, printer 12,
The label tape winding drive device 34 is further guided to the peeling table 14, and the label tape is wound up by the winding device 17.

The above-mentioned stop position detection device 11 is composed of a light emitting element and a light receiving element, and functions to accurately stop the label L to be printed at the position shown in Fig. 2. (The diagram is shown ignoring the dimensional ratio of each part.) At this position, the required data is transferred to the print drum 18 in the printer 12.
is printed by the hammer 19 and by the stamp device 35 operated synchronously with the hammer 19. The label tape winding drive device 34 is composed of a drive roller 15 and a pressure roller 16. When winding the label tape T, the drive roller 15 rotates in the direction of the arrow, that is, counterclockwise; It can also rotate in any direction.

Although the embodiment of the present invention is configured as described above,
Next, this effect will be explained.

After the label tape is filled, the pressure roller 32 of the label tape drive device 30 is released, and the presser device of the guide section 10 presses the label tape T. When a label issuing command is given in such a state, the label L stopped at the position shown in Fig. 2
The printer 12 and stamp device 35 operate to print the required data, and as the label tape winding drive device 34 is driven, the printed label L is moved in the direction shown by arrow A in FIG. 3 (forward direction). ) is driven by. At this time, the label tape T is bent at an acute angle by the edge of the peeling table 14, so that the printed label L' is removed from the backing paper 2 as shown in the figure.
Detached from 0. Detecting the time point of this peeling (for example, the label tape winding drive device 34 is driven for a predetermined time from the time when the stop position detection device 11 detects the stop position of the label until the label is peeled off; detecting this predetermined time) Alternatively, in FIG.
A light emitting element and a light receiving element may be arranged above and below near the outer edge of the label, and detection may be performed by emitting light again after the light is blocked by the label to be peeled off. ) by the label tape drive device 30
The pressure roller 32 is pressed against the label tape T, and the drive roller 31 rotates counterclockwise.
At this time, the pressure roller 16 of the lower label tape winding drive device 34 may be released, or the drive roller 15 may be configured to rotate clockwise. As a result, the portion of the backing paper 20 from which the label has been peeled moves in direction B (in the opposite direction) and reaches the printing position, at which point the rotation of the drive roller 31 is stopped and the drive roller 15 is also rotated as described above. If necessary, this will also be stopped.

Although not shown here, a data portion for journal printing is selected in the printing drum 18 and the stamp device 35 in response to a signal from the tallying unit or the accumulator, and predetermined data is printed on the mount 20 by these operations. Ru. For example, if the content of the label issued at this time is for beef, the weight and price will be printed on the mount 20 as data, which will be added to the cumulative total of the weight and price of beef sold up to this point. be done.

When the printing operation on the mount 20 is completed, the pressure roller 32 of the label tape drive device 30 is released again, and the label tape winding drive device 34 is released again.
The drive roller 15 rotates counterclockwise, and the label tape T moves in the direction of arrow A (positive direction) in FIG. 3. When it reaches the label printing position as shown in the figure, the drive roller 15 stops and the label Tape T
stops. In this way, the next label L'' is at the printing position in preparation for the next label printing.

As mentioned above, every time a masterpiece is sold,
That is, each time a label is issued, for example, each time beef, pork, chicken, beef, etc. are sold, the total data at that time is printed on the mount 20, and the total data can be checked at any time. Can be done. Moreover, the mount 20, which conventionally becomes useless after the label is peeled off, can be effectively used as recording paper.

Although the embodiment of the present invention is configured as described above,
Of course, the present invention is not limited to this embodiment, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, various types of total data at that time are printed on the mount 20, but instead of this, the data printed on the label may be printed as is on the mount 20. You can do it like this. In this case, the printing drum 18 and stamp device 35 may be operated as they are.

Furthermore, in the above embodiments, after printing on a label, the label tape T was driven in the winding direction to peel off the label, and then the label tape T was driven in the opposite direction for journal printing. Instead of this, after printing on the label, the label tape T is sent backwards to print on the backing paper, and then the label tape T is driven in the winding direction to peel off the printed label. You may also do so.

Further, in the above embodiment, when winding up the label tape T, the pressure roller 32 of the label tape drive device 30 is released and the drive roller 31 is stopped. 32 without releasing the drive roller 31.
may be rotated clockwise. However, in this case, it is necessary to operate in synchronization with the drive roller 15 of the label tape winding drive device 34.

Furthermore, in the above embodiment, when journal printing is performed on a mount, the drive roller 31 of the label tape drive device 32 as a label tape drive means is rotated counterclockwise, but instead of this, the label roll 1 is rotated counterclockwise. It may be arranged to drive itself in its winding direction, that is, clockwise. In this case, although the automatic label tape loading function cannot be performed, the label tape drive device 30 can be omitted.

Furthermore, in the above embodiments, the case of a so-called back room type toll scale with a label printer has been explained, but of course the present invention can also be applied to a so-called face-to-face sales type toll scale with a label printer that has a built-in label roll. .

The label printer according to the present invention has the above-described configuration, so that when the label tape driving means is rotated so that the label tape is driven in the opposite direction to the direction in which the label tape is supplied to the printer, it is possible to This has the remarkable effect of allowing journal prints to be made on top of the original mount.
