Here, the paper 10 may be understood as a concept including various kinds of paper which require printing of a coating, in addition to a thin paper currency having a predetermined shape printed on money or the like.

Specifically, the stamping unit 300 may include a coating part 310, a damping part 320, a lower support part 330, an upper support part 340, a coating driving part 350 and a damping driving part 360.

The coating unit 310 can be detachably mounted on the lower support table 330 and can print the coating on the paper 10 placed on the movement path 101 by the vertical movement of the lower support table 330. [ A mark, letter, model, letter or the like to be printed on the paper 10 can be embossed or embossed in the painting part 310 so that a paint can be printed on the paper 10 when pressed. Since the coating unit 310 is a commonly used automatic stamp, a detailed description thereof will be omitted.

The damping unit 320 may be disposed to face the coating unit 310 in order to support the paper 10 during the coating printing by the coating unit 310. The damping unit 320 may be detachably mounted on the upper support 340 and may support the upper surface of the paper 10 by the vertical movement of the upper support 340.

The lower support member 330 may be movably mounted in the vertical direction in the lower body 100b and the upper support member 340 may be mounted movably in the vertical direction in the upper body 100a.

The coating driving part 350 may be mounted on the lower main body 100b and move the lower supporting frame 330 on which the coating part 310 is mounted in the vertical direction of the main body 100. [ The coating driving unit 350 includes a painting camshaft 354 rotatably mounted on both side walls of the lower main body 100b and a sliding camshaft 354 mounted on the painting camshaft 354 and having a ledge 351a and an end 351b, A coating motor 352 for rotating the coating cam 351 and a coating spring 353 for pulling down the lower support table 330 in a downward direction. At this time, the ledge 361a can press the coating portion 310 so that the coating portion 310 contacts the paper 10 during rotation, and the end portion 351b can press the paper 10 when the coating portion 310 rotates, The pressurization of the coating unit 310 can be released.

Accordingly, when the painting motor 352 is operated, the driving force of the painting motor 352 is transmitted to the painting camshaft 354, so that the painting camshaft 354 can be rotated. When the painting cam 351 is rotated by 90 degrees, the book 351a of the painting cam 351 pushes the lower supporting table 330, and at the same time, the painting unit 310 can print the painting on the paper 10 . When the painting cam 351 is rotated 180 degrees, the end 351b of the painting cam 351 is located opposite to the lower supporting table 330. At this time, the painting spring 353 rotates the lower supporting table 330 So that the lower support member 330 can be returned to its original position.

The damping driving unit 360 may be mounted on the upper body 100a and may move the upper support 340 on which the damping unit 320 and the damping unit 320 are mounted in the vertical direction of the body 100.

At this time, the ledge 361a can press the damping portion 320 so that the damping portion 320 contacts the paper 10 during rotation, and the end portion 361b allows the damping portion 320 to move along the paper 10, The pressure of the damping unit 320 can be released.

Accordingly, when the damping motor 362 is operated, the driving force of the damping motor 362 can be transmitted to the damping camshaft 364 to rotate the damping camshaft 364. When the damping cam 361 is rotated 90 degrees, the ledge 361a of the damping cam 361 pushes the upper support 340, and the damping portion 320 can support the upper surface of the paper 10 at this time. Then, when the damping cam 361 is rotated by 180 degrees, the end portion 361b of the damping cam 361 is positioned to face the upper support 340, So that the upper support 340 can be returned to its original position.

The tongue portion 361a of the damping cam 361 has a first upper curved surface 381 including a top dead center located at a greatest distance from the damping camshaft 364 and a second upper curved surface 381 And a first contact curved surface 382 which is formed continuously on one upper curved surface 381. The holding portion 361a of the coating cam 361 is provided with a second upper curved surface 371 including a top dead center located at a greatest distance from the painting camshaft 354 and a second upper curved surface 371 including a coating portion 351 contacting the paper 10 And a second contact curved surface 372 continuously formed on the second upper curved surface 371.

When the painting motor 352 is operated with a time lag from the operation time of the damping motor 362 and the painting cam 351 is rotated in the other direction (counterclockwise in the drawing, for example) Since the first portion 351a is initially in contact with and pushes, the coating portion 310 can move upward toward the paper 10.

4, when the damping cam 361 further advances in one direction, the damping cam 361 is positioned at the top dead center (perpendicular to the upper support) The curved surface 381 can push and support the upper support 340.

The rotation of the painting cam 351 in the other direction further advances the first contact surface 351a of the painting cam 351 to the lower supporting table 330. Thereafter, While contacting the lower support member 330, the stamping unit 350 can start stamping on the paper for the first time.

At this time, although not shown, the paper 10 pushed by the first upper curved surface 381 is pressed by the second contact curved surface 372 in a state of being pushed downward by a predetermined height (about 1 mm) As the portion 310 is moved upward, printing of a clear paint can be started on the lower surface of the paper 10.

5, as the damping cam 361 further advances in one direction, the damping cam 361 moves away from the top dead center and the first contact curved surface 382 of the tongue 361a moves away from the upper support 340 ). ≪ / RTI >

The coating cam 351 is further rotated in the other direction so that the coating cam 351 is positioned at the top dead center position (perpendicular to the lower supporting table), and the second upper curved surface 371 of the holding portion 351a is moved The stamping on the sheet can be completed while pushing and supporting the sheet 330.

In this case, although not shown, the coating portion 310 pushes the paper 10 upward by a predetermined height (about 1 mm) by the second upper curved surface 371, As the damping portion supports the paper by the pressure, the printing of the clear coating on the lower surface of the paper 10 can be completed.

6, when the damping cam 361 continues to rotate in one direction, the damping portion 320 is moved upward by the damping spring 363, As shown in FIG.

As the coating cam 351 further rotates in the other direction, the coating unit 310 may be in contact with the lower surface of the paper 10 although the pressing force is released.

7, as the damping cam 361 continues to be rotated in one direction, the damping portion 320 is continuously moved upward by the damping spring 363, 10). ≪ / RTI >

The coating unit 310 is moved downward by the coating spring 353 so that the coating unit 310 can be separated from the lower surface of the paper 10 have.

[

At this time, the conveying speed of the paper 10 conveyed from the main body 100 can be controlled to be 1.4 to 1.6 times faster than the entering speed of the paper 10 entering the main body 100. For example, when the paper 10 conveyed from the main body 100 enters at a conveying speed of 277 m / s, a crawling phenomenon occurs due to temporary stop of the paper 10, 10, the conveying speed of the sheet 10 after the initial stamping can be adjusted to 404 m / s.

The operation of the stamping apparatus according to the present invention will now be described.

First, when the paper 10 enters the entrance 102 side of the main body 100 at a predetermined entry speed, the conveying motor 230 is operated by the operation signal of the controller 400, The paper 10 positioned on the side of the main body 102 can be moved along the movement path 101 to the side of the outlet 103 of the main body 100. [

That is, when the driving force of the conveying motor 230 is transmitted to the first conveying shaft 240 and the second conveying shaft 250, the first conveying shaft 240 and the second conveying shaft 250 are rotated, As the conveying roller 210 and the second conveying roller 220 are rotated, the paper 10 which has entered the entrance 102 side of the main body 100 is moved toward the exit 103 side along the movement path 101 .

When the paper 10 is moved to the center side of the main body 100 where the stamping unit 300 is located, the controller 400 temporarily stops the operation of the conveyance motor 230 and operates the stamping unit 300 The paper 10 can be stamped. At this time, the controller 400 can repeatedly apply an operation signal and a stop signal to the conveying motor 230 several times (about one to four times). At the same time, the controller 400 operates the stamping unit 300, (About one to four times) at a predetermined position.

The drive force of the paint motor 352 is transmitted to the paint shaft 354 through the driven gear 301 so that the paint shaft 354 is driven . When the painting cam 351 is rotated by 90 degrees, the book 351a of the painting cam 351 pushes the lower supporting table 330, and at the same time, the painting unit 310 can print the painting on the paper 10 . When the painting cam 351 is rotated 180 degrees, the end 351b of the painting cam 351 is located opposite to the lower supporting table 330. At this time, the painting spring 353 rotates the lower supporting table 330 So that the lower support member 330 can be returned to its original position.

Such vertical movement of the damping unit 320 and the coating unit 310 can be repeatedly performed several times (about one to four times) by the operation signal of the controller 400. In this case, The coating can be continuously printed on one to four places of the substrate 10.

The operation signal of the controller 400 is sequentially applied to the damping motor 362 of the damping unit 320 and the paint motor 352 of the paint unit 310 so that the damping unit 320 and the paint unit 310 The printing of the paper 10 can be smoothly performed.

In addition, after the paper 10 is first stamped, the conveying speed of the paper 10 conveyed from the main body 100 is controlled to be higher than the entering speed of the paper 10 entering the main body 100 . For example, after the paper 10 transported from the main body 100 enters at a transporting speed of 277 m / s and the paper 10 is first stamped by the stamping unit 300 while the paper 10 is temporarily stopped, The paper 10 is conveyed at a speed of 404 m / s after the first stamping in order to compensate for the amount of paper 10 crying, .

On the other hand, the paper 10 on which the stamp is printed in the stamping unit 300 can be moved along the movement path 101 to the outlet 103 side of the main body 100 and the paper 10 Can be discharged to the outside of the main body 100 through the outlet 103 by the second conveying roller 220.

12 is a block diagram illustrating a method of stamping paper according to an embodiment of the present invention.

As shown in FIG. 12, a method of stamping a sheet includes a step S10 of feeding the sheet, a step S20 of conveying the sheet, a step S30 of temporarily stopping the sheet, a step of stamping the sheet, (S40), and conveying and discharging the sheet (S50).

In the step (S10) of loading the paper, the paper can be fed into the moving path for stamping. At this time, the paper 10 can enter the movement path of the stamping device at a predetermined entry speed.

In this embodiment, the feeding speed of the sheet 10 that enters the moving path may be the discharging speed at which the sheet is discharged from the printer. Therefore, depending on the discharge speed discharged from the printer, the paper can enter the stamping apparatus, and the paper that has entered the stamping apparatus can be transported along the movement path of the stamping apparatus.

The step of conveying the sheet (S20) can convey the sheet fed into the movement path to the stamping position. At this time, the paper can be conveyed through the conveying roller disposed at the entrance side of the stamping apparatus.

The step of temporarily stopping the paper (S30) may temporarily stop the paper conveyed along the movement path at the stamping position. Here, the stamping position can be defined as a point at which the paper is stamped by the vertical movement of the damping portion and the coating portion.

 The step of stamping the paper (S40) may move the damping portion and the coated portion in the vertical direction and stamp the temporarily stopped paper at the stamping position. At this time, a damping portion for supporting the upper surface of the paper can be installed on the upper side of the stamping position so as to be movable in the vertical direction, and a damping portion for stamping the lower surface of the paper supported by the damping portion, As shown in Fig. Thus, the paper temporarily stopped at the stamping position can be stamped by the stamping portion, while being supported by the damping portion.

The step of stamping the paper (S40) may repeat the conveying and stopping operations of the paper along the movement path several times (about one to four times). When the paper stops, the damping portion and the coating portion As a result of repetitive movement, several sheets of paper (one to four places) can be printed on the paper 10.

The damping portion and the coating portion are successively interlocked with each other with a predetermined time difference (for example, 30 ms) during the printing of the paper sheet so that the printing and printing of the paper 10 between the damping portion 320 and the coating portion 310 Can be smoothly implemented.

This is because, when the damping portion and the coating portion are simultaneously operated, the load can be increased while overlapping the coating cam and the damping cam at the top dead center of the damping cam and the coating cam.

That is, when the damping cams and the coating cams are mutually positioned at the top dead center, that is, when the damping cams and the coating cams are positioned on a straight line, the damping cams and the cams of the coating cams are pressed against each other The damping cam and the coating cam are overlapped with each other (about 2 mm), so that the load of the damping cam and the coating cam at the start of overlap can be increased. As a result, these damping cams and the coating cams can malfunction, Noise may be generated during operation of the damping cam and the coating cam.

When the stamping of the sheet by the damping unit and the coating unit is completed, the stamped sheet can be conveyed along the movement path and discharged.

The step of conveying and discharging the sheet (S50) may convey the sheet stamped at the stamping position to the exit side of the stamping device along the movement path and discharge it to the outside. At this time, the paper can be conveyed through the conveying roller disposed on the exit side.

The step S50 of conveying and discharging the paper can control the conveying speed of the conveyed paper after the first stamping of the paper to be faster than the feeding speed of the paper.

In this embodiment, after the paper is put into the stamping device, the paper can be printed four times in four places while repeating the conveying and stopping operation four times. At this time, the paper is fed to the stamping device And the conveying speed of the sheet conveyed after the first stamping of the sheet can be controlled to be 404 mm / s.

As described above, when the paper is whirled (curled) caused by temporary stop of the paper when the paper is first stamped, the conveying speed of the paper after the first stamping is controlled to be faster than the feeding speed of the paper, It is possible to compensate the amount of paper 10 crying.
