Therefore, the foil 20 supplied closely to the pattern plate 50 and the bottom surface of each of the plurality of heating modules 200 is heated to a predetermined temperature.

5 and 9, the lifting unit 310 according to the present invention may be waiting in an initial position. Here, the initial position may be a position away from the lower positions of the heating modules 200, or may be a lower position of the heating module 200 to be subjected to the initial compression.

The main controller 700 operates the moving motor 322 to move the lift 310 along the ball screw bar 321. In this case, the main controller 700 sequentially positions the lift unit 310 at the lower positions of the heating modules 200. Here, the installation position of the heating modules 200 in which the seating plate 312 of the lifting unit 310 is sequentially positioned is set in the main controller 700 in advance. Therefore, the lifting unit 310 may be sequentially moved to the lower position of each of the heating modules 200.

Here, if the heating module 200 is five in total, the stop position of the lifting unit 310 is 5 positions.

First, the main controller 700 controls the operation of the moving motor 322 to position the lifting unit 310 under the heating module 200 in the first position through the rotation of the ball screw bar 321. In addition, the main controller 700 raises the lifting shaft of the lifting unit 310 by using the power supply unit 720. Therefore, the nonwoven fabric 10 fitted to the seating plate 312 installed on the lifting shaft is fixed to the first glyph plate 50 installed on the bottom of the heating module 200 in the first position and the first foil closely attached to the bottom surface thereof. 20). Here, since the first glyph plate 50 and the first foil 20 are heated to a predetermined temperature by the heating plate 220, the first glyph plate 50 and the first foil 20 are pressed together with the nonwoven fabric 10 in a state including a predetermined heat.

Therefore, the glyph portion of the first foil 20 having the same shape as that of the first glyph plate 50 is pressed between the first glyph plate 50 and the nonwoven fabric 10 to be heat-compressed on the outer surface of the nonwoven fabric 10. Can be printed. Accordingly, the pattern of the first foil 20 having the first color may be printed on the outer surface of the nonwoven fabric 10.

After the pattern of the first foil 20 is printed on the outer surface of the nonwoven fabric 10 as described above, the seat plate 312 on which the nonwoven fabric 10 is seated due to the return of the lifting shaft is also returned to the original position, and the main controller 700 ) Rotates the ball screw bar 321 using the moving motor 322 to move the lifting portion 310 to the lower portion of the second heating module 200. And, through the same process as described above of the second foil of the same shape as the pattern of the second glyph plate installed on the bottom of the second heating module 200 on the nonwoven fabric 10 is printed on the glyph portion of the first foil (20). The pattern is heat pressed. Therefore, the pattern portion of the second foil 20 is heat-compression-printed on the nonwoven fabric 10.

In the present invention, the first non-woven fabric 10 is formed on the outer surface of the nonwoven fabric 10 through the heat pressing process of the nonwoven fabric 10, the pattern plate 50, and the foil 20 due to the movement of the lifting unit 310 and the lifting shaft elevation. Patterns of 2, 3, 4, and 5 foils may be sequentially heat-press printed. Here, the areas in which the patterns of the first, second, third, four, and five foils are heat-compressed-printed on the outer surface of the nonwoven fabric 10 are unit printing areas, and these are printed on the nonwoven fabric 10 sequentially. The entire print area can be achieved.

Therefore, the entire non-woven fabric 10 may be printed with one entire print pattern in which foil patterns of different colors are combined with each other.

Although not shown in the drawing, after all of the first, second, third, fourth, and fifth foils are printed on the nonwoven fabric 10, that is, when the lifting unit 310 is moved to the fifth position and the lifting shaft returns to its original position. The main controller 700 uses the moving motor 322 to return the lifting unit 310 to its original position (initial position), and also a message (display text or sound) about completion of printing using a separate indicator and alarm. You can also let them know.

Meanwhile, referring to FIGS. 7 and 9, the heating monitoring unit 500 according to the present invention may perform a printing process when the heating temperature values of the plurality of heating modules 200 reach a set temperature value. Can be.

In the heating of the heating modules 200, the temperature sensors 510 inserted into the heating modules 200 measure a temperature value of the heating of the heating modules 200. The measured heating temperature value is transmitted to the first controller 520. The first controller 520 receives a heating temperature value of each of the heating modules 200, calculates an average heating temperature value, and the calculated average heating temperature value is included in a preset reference heating temperature value range. The operation of the foil supply unit, the lifting unit 310 and the moving unit 320 may be controlled according to whether or not.

That is, when the average heating temperature value is included in the reference heating temperature value range, the first controller 520 proceeds to the printing process through the foil supply and printing unit 300, and if not included, the foil supply and printing process You can stop it. Of course, when stopped as described above, the first controller 520 may generate an alarm to the outside using a separate alarm device. Therefore, it is possible to prevent the printing of the foil 20 pattern on the nonwoven fabric 10 from abnormally heat-pressing printing in a state in which each heating module 200 achieves an abnormal or non-uniform heating temperature.

Meanwhile, referring to FIGS. 8 and 9, the multicolor foil printing apparatus for nonwoven fabric may further include a foil supply monitoring unit 600.

The optical sensor 610 measures the winding amount of the foil through light emission and light reception to the foil 20 wound around the supply roller 410 in the vicinity of the supply roller 410, and measures the measured winding amount in a second manner. Send to the controller 620. The optical sensor 610 is a sensor having a light emitting unit 611 and a light receiving unit 612.

The second controller 620 stops the operation of the foil supply unit, the lifting unit 310, and the moving unit 320 when the winding amount reaches a predetermined limit winding amount. In addition, the second controller 620 may generate an alarm to the outside using the alarm generator 630 when the limit winding amount is reached. Accordingly, the amount of foil wound in the plurality of unit foil supply units 400 may be monitored in real time.
