Abstract

PURPOSE:To enable a change of display contents to be viewed even when the movement of a coated electric conductor becomes fast by providing a control signal correcting circuit which corrects a delay due to the distance between a printing roll and a pattern input means. CONSTITUTION:The printing roll 16 is rotated to print character patterns K1, K2... on the moving coated electric conductor 15. Then the sensor part in a printing pattern specifying means 2 sends its signal to the arithmetic circuit in the means 2 every time a mark 51 is detected, and this circuit counts up to prescribed values and then sends a control signal A to the control signal correcting circuit 31. The circuit 31 delays the signal A by prescribed seconds after inputting the signal, and sends an image latching signal B to the pattern input means 4, so that the pattern K1 is displayed on a display part 7 through an image data storage part 32. Then the sensor part detects a mark 52 corresponding to the pattern K2, which is displayed on the display part 7 as mentioned above.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a coated wire surface printing system equipped with a printing roll that continuously prints a plurality of patterns composed of a plurality of characters or symbols on the surface of a coated wire.・Relating to a print monitoring device for computers.

[Prior Art] The present inventors previously developed an emboss printing monitoring device for a covered wire surface printing system, which is equipped with a printing roll that continuously embosses a plurality of patterns on the surface of a covered wire, as shown in FIG. developed.

This embossed printing monitoring device 40 includes a printing pattern specifying means 20, an image data processing means 30, and a pattern inputting means 4. Section 7 is connected and equipped. 16 indicates a printing roll for embossing printing.

8 is a supply, 9 is an extruder, and 10 is an auxiliary water tank.

11 is the main water tank, 12 is the take-up roller, 13 is the winding a, 1
5 indicates each covered electric wire.

The printing roll 16 is pressed against the covered wire 15, and three character patterns Kl, 2. It has a function to emboss 3 on the printing roll 2, and grooves P1 to P3 are provided on the engraved surface of the printing roll 2 to print the letters +, 2 on, and 3 on each character pattern (see Fig. 5). Marks 51, 52, and 53 for indicating the position of the first character of each pattern are added to the sides thereof, as shown in FIG. 4.

The embossing print monitoring device 40 configured as described above operates as follows.

The printing pattern specifying means 20 identifies each mark 51, 52, 53.
Each time , a control signal (A1) for human power is outputted to the image data processing means 30 for each pattern. It is sent to the input means 4. As a result, the pattern input means 4 converts +, 2, and 3 into image data for each pattern emboss-printed by the printing roll 16 and sends them to the image data processing means 30. The image data processing means 30 converts each image data into image data. The image data is temporarily stored and the stored contents (image data) are sent to the display section 7, and the display section 7 sequentially displays these image data as still images.

[Problems to be Solved by the Invention] However, as described above, when the embossing print monitoring device 40 in the prior art detects the marks 51, 52, and 53 by the print pattern specifying means 20, the emboss print monitoring device 40 in the above-mentioned prior art detects the marks 51, 52, and 53 almost simultaneously for each pattern. A control signal (A+) (image latch signal (B1)) for converting 2 and 3 into image data by the pattern input means 4 is output. However, in reality, as shown in FIG. 8, due to the system configuration, only the printing roll 16 and the pattern input device! '44, so the control signal (A1) is sent immediately after the marks 51, 52, and 53 provided on the printing roll 16 are detected.
is output to the pattern input means 4, the detected mark 5
1, 52. The character pattern corresponding to 53 is 1. 2,
3 could not be displayed on the display unit 7, and the reliability of the embossing printing device 40 was disadvantageously reduced.

[Object of the Invention] The present invention improves the problems of the prior art and provides a highly reliable embossing system that can reliably display an intended character pattern even if the printing roll and pattern input means are installed at a distance. The purpose of the present invention is to provide a print monitoring device.

[Means for Solving the Problems] Therefore, in the present invention, a printing roll that continuously prints a plurality of character or symbol patterns on the surface of a covered electric wire is connected and equipped, and each printed pattern is identified and each pattern is imaged. a printing pattern specifying means for outputting a control signal for converting the image into a pattern; a pattern inputting means for inputting each of the patterns as image data in response to the control signal; and a pattern inputting means for inputting the image data each time the control signal is input. In a print monitoring apparatus, the image data processing means outputs the stored contents of the print roll to an external terminal and updates the stored contents when the next control signal is input, the image data processing means outputs the stored contents of the print roll and the pattern input. The above object is achieved by adopting a configuration including a control signal correction circuit for correcting the time delay caused by the distance between the control signal and the device.

[Embodiment] Hereinafter, an embodiment of the embossing printing monitoring device according to the present invention will be described based on FIGS. 1 to 7. Here, the same reference numerals are given to the same components as in the conventional example described above.

The embossed print monitoring device 1 shown in FIG. Each of the means 3 is connected and equipped with an illumination means 6 and a display section 7 as shown. Reference numeral 16 denotes a printing roll, which is constructed in substantially the same manner as the conventional example described above.

indicates each covered wire.

The printing pattern specifying means 2 detects the printing roll 1 as shown in the figure.
6, each mark 51, 52, 53 provided on the side surface of the printing roll 16 is sequentially detected, and each pattern is individually input as image data to the pattern input means 4 at a predetermined timing. It has the function of outputting control signal A for Specifically, this printing pattern specifying means 2 identifies each mark 51, 52 as shown in FIG.
A sensor section 12 that detects .degree. The control signal calculation circuit 11 has a function of sending data to the pattern input means 4 via the control signal calculation circuit 11.

F = (GXH) + 1 (1) where G is the number of marks provided on the side surface of the printing roll 16, and H is the number of rotations of the printing roll 16 to output the control signal A once. This is a number that indicates whether

For example, in the case of this embodiment, G=3. If H=8 is input to the control signal calculation circuit 11, F becomes F-25 from equation (1), and the control signal calculation circuit 11 performs control once every 25 times the mark detection signal is input from the sensor section 12. The signal A will be output to the image data processing means 3. In other words, if mark 51 is detected nine times, once on the ninth time,
Control signal A is output, and then when mark 52 is detected 9 times, control signal A is output once at the 9th time, and mark 5 is detected thereafter.
3, the same calculation is performed, thereby preventing the pattern to be imaged by the pattern input means 4 from being updated one after another even if the moving speed of the covered electric wire 15 becomes faster.

The image data processing means 3 includes a control signal correction circuit 31 having a function of inputting the control signal A, delaying it for a predetermined period of time, and outputting it to the pattern input means 4 as an image latch signal B.
Then, image data indicating 1, 2, or 3 is temporarily stored in the pattern sent from the pattern input means 4 based on the image latch signal B, and when the next image latch signal B is input, the contents are stored. The image data storage section 32 has a function of sequentially updating, and the lighting control section 33 is provided near the pattern input means 4 and controls the brightness of the illumination means 6 that supports 1 to 3 images for each pattern. It is configured. Specifically, the control signal correction circuit 31
Each pattern has a function of correcting 1 to 3 differences in the timing of imaging based on the installation interval between the pattern input means 4 and the pattern input means 4. For example, when the printing roll 16 rotates 8 times and the printing pattern specifying means 2 outputs a control signal A specifying pattern 1, when the pattern 2 actually enters the field of view of the camera of the pattern inputting means 4. is 1+(seconds) later, the output of control signal A is delayed during that time,
Adjustment is made so that the control signal, that is, the image latch signal B, is sent to the pattern input means 4 at a timing when the pattern input means 4 can form an image. This makes it possible to accurately image 1 to 3 in each pattern.

The pattern input means 4 has a function of instantaneously inputting each pattern K + and K 21 to 3 as image data based on the image latch signal B.

Next, the specific operation of this embodiment will be explained based on FIGS. 4 to 7.

First of all? ll! ! The covered wire 15 moves at a linear speed T [m/s] in the X direction in FIG. shall be taken as a thing.

The printing roll 16 rotates in the X direction in FIG. 3 are sequentially embossed onto the surface of the covered electric wire 15. In this case, as described above, each time the sensor section 12 detects the mark 51, it sends the detection signal to the control signal calculation circuit 11. Subsequently, the control signal calculation circuit 11 sends the control signal A to the control signal correction circuit 31 after counting the detection signal nine times. After the control signal A is input, the control signal correction circuit delays the control signal A by, for example, 1+ seconds, and sends the image latch signal B to the pattern input means 4. by this,
As shown in FIG. 6, the pattern input means 4 inputs 1 as image data to the character pattern centered on 81 points in the figure.

Sl indicates the field of view of the pattern input means 4, and the image data storage section 32 temporarily stores 1 in the character pattern and sends the stored contents to the display section 7. FIG. 7(a) shows the display contents in this case.

Next, after outputting the control signal A corresponding to 1 in the character pattern, the sensor section 12 detects the mark 52 corresponding to 2 in the character pattern, and sends the detection signal to the control signal calculation circuit 1.
Send to 1. Control signal calculation circuit 11 and control! The l signal correction circuit 31 repeats the above-described operation and sends the image latch signal B to the pattern input means 4. Then, the pattern input means 4 converts the character pattern 2 and Ks into an image every time the image latch signal B is input, and sends it to the image data storage unit 32. The image data storage unit 32 sequentially stores the character pattern 2 and Ks, Based on this, the 0 display section 7 sends the character pattern 2 and 3 to the character pattern as shown in FIG. 7(b).

Display as shown in (c). The display section 7 displays each mark 51. as described above. ．． 52 and 53 respectively, once the printing roll 16 rotates 8 times, the display contents are as shown in Fig. 7 a → b
→C, so even if the moving speed of the covered wire 15 becomes faster, by adjusting the settings of the control signal calculation circuit 11 accordingly, the change in the display content on the display unit 7 can be made at a time interval that is sufficiently visible. In this embodiment, it is set to change at intervals of 2 to 3 seconds.

Since the present embodiment is configured as described above, the characters and patterns Kl embossed on the covered electric wire 15 are 2.
Now visual monitoring of step 3 can be easily performed, and if a printing defect is discovered during printing, the printing roll 5 can be checked.
This is practical because it allows temporary printing defect avoidance work such as adjusting the pressure of the press.

In the case of emboss printing, printing defects often occur due to the engravings on the printing roll 5 becoming clogged, so it is not always necessary to include all character patterns printed on the covered wire 15.
, 2, and 3 each time, the purpose can be achieved. Furthermore, although this embodiment has described emboss printing, this may be applied to a printing device using ordinary ink.

[Effects of the Invention] Since the present invention is configured as described above, the operation of the control signal correction circuit ensures that the intended characters are printed even if the printing roll and the pattern input means are installed at a distance. It is possible to provide a highly reliable print monitoring device that can display patterns.
