[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to a label printing and pasting apparatus for pasting the label on a product, and more specifically, a device for selectively printing a plurality of types of labels and pasting it to a product, and having a small-sized label printing and pasting. Related to the device.

[0002]

2. Description of the Related Art As a label printer for printing and issuing labels to be attached to products, the present applicant has already proposed a printer for selectively printing and issuing different kinds of labels (Japanese Patent Application No. 62-20008). And Japanese Patent Application No. 62-127339 (see the specification and drawings attached to the respective applications).
The proposed label printer includes a plurality of printing devices capable of issuing different types of labels, and labels are selectively issued from each printing device.

[0003] In recent years, automatic weighing / packaging and price-setting machines for continuously weighing, packaging, and valuing products have become widespread for making packed products. In such an automatic weighing / packaging / pricing machine, a flexible system for selectively using a plurality of types of labels is required. As a method for responding to such a demand, it is conceivable to incorporate the already-proposed label printer described above. For example,
When a label printer equipped with two printing devices is incorporated, as shown in FIG. 17, the first and second printing devices A,
When B is juxtaposed and the product is located at the specified labeling position
To, first, or second printing apparatus A, it is considered to function B.

[0004]

However, when the automatic weighing / packaging / pricing machine is constructed as described above, the labeling positions of the printing device A and the printing device B are shifted and different. For this reason, when the time from the detection of a product by a sensor (not shown) at a fixed position in the transfer line L to the time when the label is applied is the same, the time when the label is applied by the printing device A is different from the time when the label is applied. When affixed by the device B, the label affixing position on the product is shifted. In FIG. 17, Pa is the sticking position by the printing device A, and Pb is the sticking position by the printing device B.

[0005] As a method for solving such a shift in the sticking position, a volume for adjusting the label sticking position is provided in each of the printing device A and the printing device B, and after the product is detected by the sensor and the label is stuck. By adjusting the volume so that the printing time is different between the printing apparatus A and the printing apparatus B, it is possible to make the sticking position of the label on the product the same.

[0006] However, such adjustment requires a number of trials of sticking of the label, which is very troublesome. In addition, every time the adjustment is performed, some labels are printed in vain. There is a disadvantage that it must be done. Also,
If the label attaching positions of the printing device A and the printing device B are different, there is a problem that the moving distance of the product required for attaching the label becomes long, and the degree of freedom of the configuration of the device is limited. .

In general, an automatic weighing / packing / pricing machine that prints and issues one type of label and attaches the product weighed by a weighing machine C to a packaging machine D as shown in FIG. At the coming position S, the packed product is shifted to a fixed position, a label is attached to the product at the position S, and the product is transported in the direction of the arrow.

Accordingly, in combination with packaging machine D the label printer described above, when attaching the Oite selectively in a plurality of types of labels in different labeling position, inevitably, to ensure a long space position S Therefore, there is a problem that the size of the entire apparatus is increased. The present invention has been made under such a background, and does not require troublesome adjustment even when a plurality of printing devices selectively attach different kinds of labels, and the number of printing devices increases. Even so, it is an object of the present invention to provide a label printing / pasting apparatus which can suppress an increase in the size of the entire apparatus.

Next, the controller of the automatic weighing / packaging and pricing machine having the mechanical configuration described above, that is, the electrical configuration will be described. FIG. 9 is a system configuration diagram. In the figure, a control section on the label printer side regarding the first and second label printers 100 and 200 including the weighing section 10 and a control section on the automatic packaging machine side regarding the automatic packaging machine 20 are shown. And divided into parts. The latter control section on the automatic packaging machine side has the same configuration as that of a general configuration, and a description thereof will be omitted.

On the other hand, in the former control section,
The components of the first and second label printers 100 and 200 are separately shown as a label printing unit 50, a label attaching unit 60, and a labeler rotating unit 70. The label printing unit 50 includes a first labeler 51 corresponding to a label print issuing function unit in the first label printer 100, a second labeler 52 corresponding to a label print issuing function unit in the second label printer 200, The print control unit 53 controls the first and second labelers 51 and 52.

The label pasting section 60 corresponds to a label pasting function section in the first and second label printers 100 and 200. Specifically, a packed product that has been packaged is placed at a predetermined label pasting position P. When the width is adjusted,
This is a switching valve for intake and exhaust, which is controlled so that a label printed and issued from one of the first and second label printers 100 and 200 is attached to a packed product.

The labeler rotating unit 70 is a functional unit for integrally rotating the first and second label printers 100 and 200 by 180 °.
A motor 319 that rotates the shaft 314 using the detection signals of the sensors 22 and 322 as feedback signals. The CPU 81, the ROM 82, the RAM 8
3. The display / operation unit 84 and the INF circuit (interface circuit) 85 for the automatic packaging machine include a console unit 80
(See FIG. 2).

Hereinafter, the main part of the control unit on the label printer side will be described in detail. The ROM 82 stores a control program described later. RAM
As shown in FIG. 10, the working area 83 has a working area 83a for registers, flags, various buffers, etc., and also has a preset data file 83b and a total data file 83c.

As shown in FIG. 11, in the preset data file 83b, data for printing a label with a price such as a unit price, a tare amount, a product name, a type of a used labeler, Packaging parameters for automatic packaging machine control are stored in advance, and are called by simply entering a product number when a label is issued.
The illustrated example is the preset data corresponding to the product number “125”, the unit price “150 (yen)”, and the tare weight “3”.
(G) ", the product name" pork top ", the labeler used" first labeler ", and the packaging parameter" 3 ".

The packaging parameters are parameters specified according to the film length, the tensile strength, and the tray type. The automatic packaging machine 20 determines whether the type of the pack product or the size of the tray is based on the parameters. Regardless, the finished packaging will be performed. (JP-A-61-2
87508). Total data file 83c
Is a file that totals label issuance results (pricing results) for each product number.

The working area 83a is provided with a label print buffer for storing the print data of the previously weighed product in addition to the print data of the currently weighed product (see FIG. 12). Then, when a print command is issued due to the weighing stability of the product to be weighed this time, first, a label is printed and issued with the print data of the previously weighed product,
The label data is printed and issued based on the print data of the weighed product as the print data of the weighed product last time.

Therefore, the label is always printed and issued one time before the print data of the currently weighed product, that is, the print data of the previously weighed product.
The reason for this is that only one previously weighed product always stays in the product transfer line between the product weighing unit 10 and the labeler. In the example shown,
The data in the upper column of FIG. 12 is the print data of the previously weighed product, and the data in the lower column of FIG. 12 is the print data of the currently weighed product. First, print the label using the data in the upper column as print data, then print and issue the label using the data in the lower column as print data, and then print the label using the data in the lower column as print data. It will be issued.

The display operation section 84 (see FIG. 9) displays print data and the like on a full screen of liquid crystal dots, and can input various data using a touch panel. And INF circuit 85 of the label printer, between the INF circuit of the automatic packaging machine side, as the data received from each other, other mutual status information, from the label printer side to automatic packaging machine, the packaging control data (Film length, tray type, film tension) are sent. Further, the automatic packaging machine side to Raberupu <br/> phosphorus data side, transversely shifting completion signal of the product is transmitted. FIG. 13 shows the configuration of the labeler rotating unit 70 and the detector 322.

And I / O ports 72 and 73, the CPU 81 of the label printers 100 and 200.
It is connected to the.

Next, the operation will be described (see FIG. 14). First, the display operation unit 84 displays the product number of the product to be weighed.
The preset data corresponding to the product number is called from the preset data file 83b of the RAM 83 and stored in each register (step S1). Thereafter, the weighing data of the product placed on the weighing dish 11 (see FIG. 1) of the weighing unit 10 is worked on (step S2). Then, it is determined whether the weighing has been stabilized (step S3).

When the weighing is stabilized, the price of the product is calculated based on the weighing data at that time, and the calculated price is stored and displayed on the display operation unit 84 (step S4). Thereafter, one of the first and second labelers 51 and 52 is set as a use labeler based on the preset data (step S5). The labeler setting process will be described later.

Thereafter, the automatic packaging machine 20 is started (step S6). Specifically, a packaging start signal and packaging parameters are transmitted to the automatic packaging machine 20. Automatic packaging machine 20
Assumes that it is in a bootable state,
Start packaging the product. Therefore, the loading of the goods into the automatic packaging machine 20 is started, and the packaging and unloading of the goods previously loaded are performed.

Thereafter, a label is printed based on the print data of the previously measured product (step S7). The labeler that prints the label is the first label set in step S5.
Labeler 51, or at the second labeler one of -5 2. After label printing, the print data of the currently weighed product is used as the print data of the previously weighed product. Thereafter, it is determined whether or not the width adjustment completion signal has been transmitted from the automatic packaging machine 20 (step S8). That is, it is determined whether or not the packaged product has been moved to the predetermined label attaching position P.

When the width adjustment completion signal is input, the label printed in step S7 is attached to the product at the label attaching position P (step S9). Of course, the labeler to which the label is attached is the first label set in step S5.
Labeler 51, or at the second labeler one of -5 2. In order to attach the label, specifically, a switching valve for intake and exhaust between the labeler and the blower is driven by a solenoid to blow air on the label. After the label is attached, the print data is stored in the total file 8 in the RAM 83.
3c.

Next, the labeler setting process in step S5 will be described (see FIG. 15). First, it is determined whether or not the labeler designation of the print data is the first labeler 51 (step S51). If the first labeler 51 has been designated, the process proceeds to step S52, and it is determined whether the first labeler 51 has been set. That is, 2
It is determined from the detection signals of the two detectors 322 and 322 whether or not the first labeler 51 is set directly above a predetermined label sticking position P.

If the first labeler 51 has already been set, the labeler setting process ends, and the flow advances to step S6 in FIG. On the other hand, when the first labeler 51 is not set, the process proceeds to step S53, and the motor 31
9 is rotated rightward in FIG. 6 to set the first labeler 51 right above the label attaching position P. And the detector 32
It is determined whether the first labeler 51 is set from the detection signals 2,322 (step S54). If the determination is not "YES" within the predetermined time, the motor 3
19 is stopped, and the fact is displayed on the display operation unit 84. When the first labeler 51 is set, the motor 3
19 is stopped (step S55), and the labeler setting process ends.

On the other hand, if the labeler designation of the print data is the second labeler 52, the flow advances from step S51 to step S56 to determine whether or not the second labeler 52 is set. That is, the two detectors 322 and 322
It is determined whether or not the second labeler 52 is set directly above the predetermined label sticking position P from the detection signal. If the second labeler 52 has already been set, the labeler setting process ends, and the process proceeds to step S6 in FIG.

On the other hand, if the second labeler 52 is not set, the process proceeds to step S57, in which the motor 319 is rotated to the left in FIG. 6 to set the second labeler 52 directly above the label attaching position P. . And detectors 322, 3
It is determined whether the second labeler 52 has been set based on the detection signal of Step 22 (Step S58). If the determination does not become “YES” within the predetermined time, the motor 319 is stopped, and the fact is displayed on the display operation unit 84. When the second labeler 52 has been set, the motor 319 is stopped (step S59), and the labeler setting process ends.

[0052] In the above example, label printer
Although the labeler rotating unit 70 is controlled by the CPU 81 on the side, the labeler rotating unit 70 is not limited to this, and may be controlled by the CPU on the automatic packaging machine side . The point is that it is only necessary to control the labeler rotating unit 70 so that the labeler selected based on the preset data corresponding to the product number is set at the predetermined label attaching position P, and the specific control method is not specified. When the control is performed by the CPU of the automatic packaging machine, the following two methods are conceivable.

[0053] In the label printer side, it is determined whether it is necessary to set switching labeler transmits a start command and the motor 319, the data of the rotational direction with respect to the automatic packaging machine side <br/> . In the label printer side, without determining whether it is necessary to set switching labeler, the labeler switching command to the automatic packaging machine, the transmit using labeler data in its automatic packing machine, the labeler It is determined whether set switching is necessary.

In the above embodiment, the used labeler is set based on the preset data corresponding to the product number. However, the labeler is not limited to this, and is used from a reservation file provided separately from the preset data file 83b. A labeler may be set. That is, in the reservation file, various kinds of print data such as selection of a label type can be stored in advance in correspondence with the product number, and a labeler to be used can be set based on the data.

In this case, the promotion label can be one of the label types. The promotion label has the same shape and print format as a general weighing label (label with value), but differs in the color of print data or the content of pre-printing. In any case, by inputting a product number, data stored in advance corresponding to the product number may be read, and a labeler may be selected based on the read data.

In the above embodiment, the label is printed after the labeler setting process is completed. However, these operations can be performed in parallel. In the above-described embodiment, the automatic packaging machine 20 is started after the labeler setting processing is completed. However, the labeler setting processing can be performed while the automatic packaging machine 20 is operating.

For example, the configuration is such that, after one cycle of the automatic packaging machine 20 is completed, the packaged product is stopped at the label affixing position P, and the labeling is performed within one cycle in which the automatic packaging machine 20 packages one product. When the setting process is completed, the automatic packaging machine 20 can be operated continuously, and the packaging processing capacity does not decrease. Further, when the product after packaging is stopped at the label affixing position P at the end of one cycle of the automatic packaging machine 20, the labeler setting process is not completed within one cycle of the operation of the automatic packaging machine 20. The automatic packaging machine 20 may be started after the labeler setting process is completed and after the label is attached.

In general, the operations of the automatic packaging machine 20 and the labeler need only be in a relationship that satisfies the conditions of FIG. 16A or FIG. 16B. In any case, the labeler setting process and label printing may be completed by the time point t _O at which the packaged product moves to the label attaching position P.

In the above embodiment, the label printer 1
This is an example of application to an automatic weighing and packaging valuation machine in which the automatic wrapping machine 00 and 200 and the automatic wrapping machine 20 are integrated, but is not limited thereto. It is also possible to apply to a high-speed weighing machine. Automatic weighing and value weighing machine Loads a product on a measuring instrument, stops the product, weighs the product, removes the product from the measuring device, and attaches a label to the product. Machine. Automatic high-speed weighing and pricing machine A valuation machine that weighs goods while transporting the goods by a weighing conveyor, and then attaches a label to the goods. Further, the present invention is also applicable to a pricing machine without a measuring device, for example, a pricing machine for fixed-price products.

Further, in the above-described embodiment, the label sticking timing is set based on the width shift completion signal when the operation of shifting the product to the predetermined label sticking position P is completed. However, the present invention is not limited to this. . For example, the commodity sensor may detect that the commodity has reached the label attaching position P, and determine the label attaching timing based on the detection signal.

The first and second label printers 1
00 and 200 may be selectively moved to the set position by means other than rotation, for example, means such as a slide. Further, the number of labelers is not limited to two, and it is needless to say that two or more labelers may be provided.

[0062]

As described in the foregoing, according to the present invention, in the case of selectively attaching a heterogeneous label by a plurality of labeler, regardless of the number equipped labeler, by securing only one labeling position No complicated adjustment is required. Further, it is possible to suppress an increase in the size of the entire apparatus due to an increase in the number of labelers . In addition, the present invention
According to the air suction, even if multiple labelers are installed
・ Only one spraying means is required, so the whole device
Is reduced in size and the cost is reduced accordingly.
