Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an inkjet recording device, and particularly to an inkjet recording device that controls the size, character width, and writing start position of printed characters.

[Background of the invention]

In recent years, there has been a trend in the food and beverage industry to create product series based on the content capacity and consumer tastes. Along with this, we have created a series of products with different sizes and package shapes for each lot.
Switching production is performed on the same conveyor line.

In such cases, if the size and shape of the package is different, the printing location and font size of the product manufacturing date, lot number, etc. may need to be changed. At times like this, Japanese Patent Application Laid-Open No. 57-9686
As described in Publication No. 5, there is a method of setting a printing location related to the starting position of printed characters by using a method of counting the starting position counter in units of one vertical line of printed characters, and
As described in Publication No. 26389, a method is used in which the character width is changed by changing the ratio of ink particles collected to the ink particles used for printing, but conventionally information such as the character height etc. To set and change the control constants,
The operator would set new data using keyboard switches on the control panel.

Therefore, if there are many types of products produced on one conveyor and the product types are changed frequently, if you set the writing position, character width, and height information each time, the time required for the settings can no longer be ignored. , resulting in a decrease in production efficiency. In addition, since humans intervene each time, there is a problem that text information may be set incorrectly.

[Purpose of the invention]

In a production system that produces a wide variety of products and frequently changes product types, the present invention provides an easy way for an operator to set information such as the printing location, character width, and size of printed characters each time the product type is changed. The purpose of the present invention is to provide an inkjet recording device that does not require such human intervention.

[Summary of the invention]

The configuration of the inkjet recording apparatus according to the present invention is such that printing is performed in response to input from a recorded object discriminator configured to discriminate the type of product and a recorded object detector configured to detect the product. In the inkjet recording device,
One of the height, width, and start position of the printed characters,
Alternatively, a character information registration section capable of registering a plurality of data relating to an arbitrary combination is provided, and the height, width, and writing position of the printed characters can be determined by input from the recorded object discriminator. The printer is configured to select and print one of a plurality of registered data relating to one or any combination of registered data.

Additional information is as follows.

The present invention uses a judgment signal from a detector that discriminates the type of product flowing on a conveyor to select information corresponding to the judgment signal from among information such as the starting position, character width, and size of printed characters registered in advance. By changing the settings, it is possible to properly print on products of different sizes and shapes.

[Embodiments of the invention]

Examples of the present invention will be described with reference to each episode.

FIG. 1 shows a production line printing system using an inkjet recording device according to an embodiment of the present invention.

The recorded object discriminator 2 detects the recorded object 3 flowing on the conveyor 6.
The discrimination mark 4 on the surface of the inkjet recording apparatus 1 is read, encoded, and input as discrimination signal data to the inkjet recording apparatus 1.

The mark 4 may be of any type as long as it can be identified optically, mechanically, magnetically, etc., such as a bar code, alphanumeric characters, or a color mark. Further, if the recorded object discriminator 2 can determine the recorded magnetism (type) based on the size and shape of the recorded object 3, the discrimination mark 4 is not required.

The inkjet recording apparatus 1 detects the recorded object 3 by the recorded object detector 5, and after a certain delay time, prints the set print content on the recorded object 3 by the print head 18. It is something that exists. FIG. 2 is a block diagram of one embodiment of the present invention.

The inkjet recording device 1 has a print character height of 1
Data input regarding the width and writing start position is performed using the operation input section 12.

The main control section 10 registers the input data in the character information registration section 13.

Here, FIG. 3 is an exemplary diagram showing the contents of the character information registration section]3.

In this embodiment, there are four types of registered data, 82 to S5, regarding the data group of the height, width, and writing position of the printed character, and each of the height data T2 to T5 is 1 byte, and the width data is 82 to S5. W2 to W5 are 2 bytes each, data P2 at the writing position
~P5 is composed of three bars each.

Note that Sl indicates a setting area.As will be described later, the area in which registered data 82 to S5 are transferred is shown, and the illustrated area shows the area in which registered data S2 is transferred.

As described above, the recorded object discriminator 2 determines the type of the recorded object 3.

This is designed to output data corresponding to four types of recording materials. Based on this discrimination signal data, the above-mentioned main control section 10 selects data corresponding to the discrimination signal data from among the registered data 82 to S5 registered in the character information registration section 13 and sends it to the character information setting section 14. It is to be transferred. These procedures are then programmed into the storage unit 11.

15 is a write start timer, 16 is a character width counter, and 17 is a staircase wave storage section. These will be explained in detail with reference to FIG. 4 along with the explanation of the above procedure.

That is, first, discrimination signal data is taken in. In this embodiment, it is checked whether this signal is the same as -ta of 0, 1, or 2.3. If they are the same, exit without processing. If they are not the same, the process moves on to address calculation of the registered data based on this different signal data. ...Block 31 Letting N be the separate signal data, it is determined by the following equation.

Y=X+6N (6 is based on 6 bytes) In the case of FIG. 3, when job-specific signal data N=O, the address calculation value Y=¥4200, and data S2 is selected. ...Block 32 Next, this selected registration data S2 is transferred to the setting area S1 of the character information setting section 14. At this time, the character height T2. of the registered data S2. W2 in text, writing position P2
are transferred to Tl, Wl, and PL of setting area S1, respectively.

...Block 33 Next, it is checked whether the character height data T1 is the same as the previous data. If they are the same, exit without processing. If there is a change, move on to creating new staircase wave data. ...Block 34 staircase wave data is stored in the staircase wave storage section 17 in FIG. 2, and is newly created every time there is a change in the character height setting.
This will be explained using figures.

The character height of the printed character C is represented by staircase wave data F1, which is the difference between one level of data v1 corresponding to each vertical dot, where vl is data corresponding to the pitch between vertical dots. Change the character height data T1 and create the staircase wave data F.
If step data v2 of 2 is changed, the printed characters will be D as shown in the figure.
It changes like this.

Therefore, by creating new staircase wave data and setting it in the staircase wave storage section 17 shown in FIG. 2, the character height can be changed.

...Block 35 Next, when the recording object 3 is detected by the recording object detector 5 shown in FIG. Location data (
In FIG. 3, PL) is set in the write timer 15. The write start timer 15 is decremented at the timing of the vertical dot scanning signal B as shown in FIG. 5, and the value of the write start timer 15 becomes 0.
Printing will start when .

Therefore, the writing position data P of the character information setting section 14
By changing 1, the printing location on the recorded object 3 can be changed.

As is clear from the above, the write start position data includes a write start position based on a preset delay time from detection of the recording object to printing.

To control the character width, when the value of the writing start timer 15 becomes O and printing starts, as shown in FIG. This can be done by controlling the number of pieces.

To explain this with reference to FIG. 2, when the value of the write start timer 15 reaches O, the number of ink particles A is set in the character width counter 16.

Then, the number of ink particles after the 8th vertical dot is counted, and the character width counter 16 is subtracted accordingly, and when the value reaches O, it is set as the generation timing of the next vertical dot 1-scanning signal. . Further, at this vertical dot scanning signal generation timing, the number of ink particles A is set again in the character width counter 16, and thereafter, this process is repeated during printing.

In this embodiment, all of the character height, character width, and writing start position can be changed, but it is also possible to change them alone, that is, one of them, or any combination thereof.

In addition, instead of the recorded object discriminator 2 that automatically changes the forehead-specific signal data depending on the recipient, a switch means that can manually set the data corresponding to the 1-category signal data described above and discriminated is provided. It is also possible to change the height, width, and writing start position of printed characters when the type of recorded object 3 is changed using this method.

As described above, according to this embodiment, with a simple configuration, it is possible to print characters in appropriate locations and with appropriate character sizes without human intervention when changing types on a multi-product production line. It is.

〔Effect of the invention〕

According to the present invention, since it is possible to print characters of an appropriate size on products of different shapes and sizes in an appropriate place without human intervention, data on the height, width, and starting position of printed characters can be
This eliminates the need to reconfigure settings when changing products, improving production efficiency.

Furthermore, the problem of the operator erroneously setting data is eliminated.

Furthermore, even if you change the conveyor speed depending on the type of product, if you register the character width and start position data according to the conveyor speed in advance, you can print properly, which is very effective, allowing you to respond flexibly to the production process. It is.
