[INVENTION Problems to be Solved point] However, mark embossed printing monitor device 40 in the prior art, corresponding to each pattern _{K 1, K 2, K 3} 51,5
Each pattern K ₁ , K ₂ , K ₃ printed every time 2, 53 is detected is imaged by the pattern input means 4, and image data processing 30
Since the stored contents are updated every time these input image data are updated, the linear speed of the coated electric wire 15 increases, the rotation speed of the printing roll 16 increases, and the printing speed increases. Updating of the display contents is accelerated, and in the worst case, there is an inconvenience that the printed patterns K ₁ , K ₂ , and K ₃ cannot be sufficiently visually confirmed.

[Object of the Invention] The present invention solves the above-mentioned problems of the prior art, and allows only a character pattern that is determined in advance to be necessary among printed character patterns to be sequentially visible without being affected by the linear velocity of a covered electric wire. It is an object of the present invention to provide a print monitoring device capable of displaying at an update speed.

[Means for Solving the Problems] Therefore, in the present invention, each of the printed patterns is specified while being connected to a printing roll that continuously prints a plurality of character or symbol patterns on the surface of the insulated wire, and each pattern is imaged. Print pattern specifying means for outputting a control signal for converting the image data, pattern input means for inputting each of the patterns as image data in response to the control signal, and storing the image data every time the control signal is input An image data processing means for outputting the stored content to an external terminal and updating the stored content when the next control signal is inputted, wherein the print pattern specifying means is provided on a side portion of a print roll. A sensor unit for sequentially detecting marks for pattern determination and outputting a control signal for mark determination, provided at least once on a printing roll. And a control signal calculation circuit for selecting a control signal for specifying one pattern from a plurality of control signals output from the sensor section in response to the control signal and sending the selected control signal to the pattern input means via the image data processing section. This is intended to achieve the above object.

[Embodiment] An embodiment of an embossed printing monitoring apparatus according to the present invention will be described below with reference to FIGS. 1 to 7. here,
The same components as those in the above-described conventional example are denoted by the same reference numerals.

The emboss print monitoring apparatus 1 shown in FIG. 1 includes a print pattern specifying unit 2, an image data processing unit 3, a pattern input unit 4, an illumination unit 6, and a display unit 7. The image data processing means 3 is provided with a lighting means 6 and a display unit 7 as shown in FIG. Reference numeral 16 denotes a printing roll, which is configured in substantially the same manner as the above-described conventional example.

On the other hand, 8 is a sabrai, 9 is an extruder, 10 is an auxiliary water tank, 11 is a main water tank, 12 is a take-up roller, 13 is a winding machine, and 15 is a covered electric wire.

The print pattern specifying means 2 includes a print roll
16, 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 by the pattern input means 4 at a predetermined timing. For outputting a control signal A for the purpose. Specifically, this print pattern specifying means 2
As shown in FIG. 3, a sensor unit 12 for detecting each of the marks 51, 52, and 53, and a signal from the sensor unit 12 is calculated based on the following equation (1), and this signal is calculated F times. A control signal operation circuit 11 having a function of sequentially sending a control signal A to the pattern input means 4 via the image data processing means 3 every time detection is performed.
It is composed of

F = (G × H) +1 Expression (1) Here, G is the number of marks provided on the side surface of the print roll 16, and H is the number of rotations of the print roll 16 to output the control signal A once. It is the number shown.

For example, in the case of this embodiment, if G = 3 and H = 8 are input to the control signal calculation circuit 11, F becomes F = 25 from the equation (1), and the mark detection signal is input 25 times from the sensor unit 12. Each time, the control signal calculation circuit 11 outputs the control signal A to the image data processing means 3 once. That is, when the mark 51 is detected nine times, the control signal A is output once at the ninth time, and when the mark 52 is detected nine times, the control signal A is output at the ninth time, Hereinafter, the same calculation is performed for the mark 53, thereby preventing the pattern input means 4 from successively updating the pattern to be imaged even when the moving speed of the covered electric wire 15 is increased.

The image data processing means 3 receives the control signal A, delays the control signal A by a predetermined time, and outputs the control signal A to the pattern input means 4 as an image latch signal B.
If, temporarily stores the image data representing the pattern K ₁ or K ₂ or K ₃ sent on the basis of the pattern input means 4 to the image latch signal B, when the next image latch signal B is input to the content Image data storage unit 32 having a function of sequentially updating
And each pattern K ₁ provided near the pattern input means 4.
It is constituted by an illumination control unit 33 for controlling the brightness of the illumination means 6 for supporting the imaging ~K _3. Control signal correction circuit 31 is specifically has a function to correct the deviation of the timing of imaging of the pattern K ₁ ~K ₃ based on installation interval between the printing roll 16 and the pattern input unit 4. For example,
Printing roll 16 is 8 rotates, when the control signal A for identifying the pattern K ₁ from the print pattern specifying means 2 is outputted, actually the the pattern K ₂ enters the camera field of view of the pattern input means 4, t _{Since the time is 1} (second) later, the output of the control signal A is delayed during this time, and the control signal, that is, the image latch signal B is adjusted to be transmitted to the pattern input signal 4 at a timing that can be imaged by the pattern input means 4. Thus, as each pattern K ₁ ~K ₃ can be imaged to accurately.

The pattern input means 4 has a function of instantaneously inputting each of the patterns K ₁ , K ₂ , K ₃ as image data based on the image latch signal B.

Next, a specific operation of the present embodiment will be described with reference to FIGS.

First, the insulated wire 15 is moved in the Y direction in FIG.
s], and the print pattern identification unit 2
The control signal A is output every time the marks 51 to 53 of 6 are detected nine times.

The print roll 16 rotates in the X direction in FIG.
K ₁ , K ₂ , and K ₃ are sequentially printed on the surface of the insulated wire 15 by embossing.
In this case, each time the sensor unit 12 detects the mark 51, the detection signal is sent to the control signal calculation circuit 11 as described above.
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
_The image latch signal B is sent to the pattern input means 4 with a delay of _one second. Thus, the pattern input unit 4 for inputting a character pattern K ₁ around the figure a _1-point as shown in FIG. 6 as image data. S ₁ indicates the field of view of the pattern input means 4. Then, the image data storage unit 32, the character pattern
K ₁ is temporarily stored, and the stored content is sent to the display unit 7. Seventh
FIG. 7A shows the display contents in this case.

Subsequently, the mark sensor 12 after outputting a control signal A corresponding to the character pattern K _1, for this time character pattern K ₂
52, and sends the detection signal to the control signal calculation circuit 11. The control signal operation circuit 11 and the control signal correction circuit 31 repeat the above-described operation and send the image latch signal B to the pattern input means 4. Then, the pattern input means 4 converts the character patterns K ₂ and K ₃ into an image for each input of the image latch signal B and sends the image to the image data storage unit 32. The image data storage unit 32 sequentially stores the character patterns K ₂ and K ₃ and sends them to the display unit 7. Based on this, the display unit 7 converts the character patterns K ₂ , K ₃ into those shown in FIG.
It is displayed as shown in (c). As described above, the display on the display unit 7 changes each of the marks 51, 52, 53 once when the print roll 16 rotates eight times, and the display content changes from FIG. Even if the moving speed of the control signal becomes faster, if the setting of the control signal calculation circuit 11 is adjusted accordingly, the change of the display content of the display unit 7 can be set to a sufficiently visible time interval. In this embodiment, it is set to change at intervals of 2 to 3 seconds.

Since this embodiment is constructed as described above, it will be able to be easily monitored by embossed printed characters and patterns K _1, K _2, K ₃ of visually covered wire 15, even during printing operation However, if a printing failure is found, a primary printing failure avoiding operation such as adjusting the pressing of the print roll 5 can be performed, which is practical.

In the case of embossed printing, the engraved groove of the print roll 5 often becomes defective due to clogging of the engraved groove. Therefore, all the character patterns K ₁ , K ₂ ,
In each case sufficiently that purpose without monitor all K ₃ can be achieved. Although the present embodiment has described emboss printing, it may be applied to a printing apparatus using ordinary ink.

[Effects of the Invention] Since the present invention is configured as described above, according to this, the functions of the sensor unit and the control signal calculation circuit allow the character pattern to be printed without being affected by the linear speed of the covered electric wire. It is possible to provide a print monitoring device capable of displaying only a character pattern that is determined to be necessary in advance from among them at an update speed at which it can be sequentially viewed.
