However, this is not intended to limit the embodiments in accordance with the concept of the present invention to a particular disclosed form, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

The embossing roll manufacturing according to the present invention is easy to laser processing, because the existing metal roll was difficult to direct laser processing due to the high hardness, by making a copper roll (Cupper Roll) with a metal roll to facilitate a laser processing while maintaining a certain hardness, Furthermore, the laser cleaning process is performed before the metal roll is processed by setting the automatic cleaning device as a set with the laser processing device so that the copper roll surface cleaning operation before the laser processing can be performed at least three times with acetone and two times with alcohol. It is characterized in that the residue including oil remaining on the surface of the inhibiting metal roll is completely cleaned so that it can be processed with high quality embossing rolls without generating laser processing defects.

To this end, the metal rolls according to the invention are mainly copper (Cu) copper rolls, which are used for embossing certain materials.

In this case, the copper roll, ie, the metal roll, consists of 99.90-99.94% by weight of copper (Cu) and the remaining phosphorus (P).

At this time, copper (Cu) may inhibit the hot workability as a component to improve the hardness, but in the present invention, since it is not intended for hot working, the copper (Cu) is for manufacturing a metal roll containing copper as a main component, and phosphorus (P) is limited to the above range. A small amount is added.

On the other hand, the embossing roll processing apparatus according to the present invention is an apparatus for forming an embossing roll by laser processing the metal roll, that is, copper roll obtained by molding the composition composed of the above-described metal component.

Such embossing roll processing apparatus includes a machining housing 100, as shown in Figure 1a, b, c.

At this time, the front and the upper surface of the processing housing 100 is made of an open structure, the open front and the upper surface may be sealed by a housing cover 110 that is rotationally open and closed.

In this case, both ends of the housing cover 110 are rotatably assembled to both sides of the processing housing 100 via the hinge shaft 112.

In addition, a guide rail 120 is installed inside the processing housing 100, and a moving chuck 130 movable along the guide rail 120 is installed, and the moving chuck 130 is provided. The fixing chuck 140 is installed inside the machining housing 100 at a position opposite to the machining housing 100.

Here, the moving chuck 130 and the fixed chuck 140 is a means for fixing and fixing the metal roll (ROL) to be processed by the embossing roll, the metal roll (ROL) is drawn small for convenience of illustration, the size can be changed have.

That is, when the metal roll (ROL) is large, the moving chuck 130 is moved along the guide rail 120 to open the interval of the fixed chuck 140, in this case it is to be spaced apart by the length of the metal roll (ROL) .

In particular, for example, an encoder may be installed in a motor that is a driving source for moving the moving chuck 130 for accurate movement operation.

In addition, the front surface of the processing housing 100 may be further provided with a display 150 to monitor the processing status, that is, the overall operating state during laser processing, and also, such as a keypad for inputting control or various set values. The control panel 160 with an input means is further provided.

In this case, when monitoring the overall operation state according to the metal roll processing can be directly linked to the driver's smart phone (CP) can be directly monitored the overall work situation can increase the work efficiency, such an example The control panel 160 may be configured in a known manner to control and have a wireless communication function.

On the other hand, the moving chuck 130 and the fixed chuck 140 may cause poor centering due to deterioration or processing error during use, and in this case, may cause processing defects during metal roll processing due to the shaking phenomenon. .

Thus, in order to prevent such a phenomenon, it may be provided with a known centering means for accurately centering the center of the mobile chuck 130 and the fixed chuck 140.

In addition, a laser processing unit 200 for laser processing the metal roll ROL is provided between the moving chuck 130 and the fixed chuck 140.

In this case, the laser processing unit 200 is fixed to the unit body 220 and the unit body 220 which is movable along the guide member 210 which is installed in parallel with the guide rail 120 at intervals. It comprises a generator 230 and a dust collector 240 fixed to the bracket at intervals from the upper surface of the laser generator 230.

In this case, the guide member 210 is controlled by the control panel 160, as shown in the upper portion of the guide rail 120, but the size and height is just like that shown in the diagram, and spaced apart at intervals in parallel It may be a crawler type timing belt or screw shaft installed.

In addition, the unit body 220 is coupled to the guide member 210 and is installed to be movable along. The laser generator 230 is a stand alone type scanner such as (a) of FIG. 2 or (b). It can be implemented in one piece.

In particular, since the scanner 250 is provided together with the scanner integrated type, the scanner 250 scans the surface of the metal roll ROL processed by the laser generator 230 in real time to read errors between the design value and the processed value. It is preferable that the defects can be stopped immediately so as to reduce the loss due to the machining defect of the metal roll ROL.

If there is no real-time scanning, after processing all the metal rolls (ROL) to the end, if the defect is confirmed, the process loss as well as the processing loss is very large. This is because there is an advantage that can be prevented.

In addition, by interlocking the scanning result to the operator's smartphone (CP) immediately, it is possible to check the cleaning state of the surface of the metal roll, so that the cleaning error can be monitored, thereby preventing the processing defect in advance. For this reason, it is better if a scanner is further provided. In this case, the real-time monitoring through the smart phone (CP) may be configured to control the control panel 160 in the manner described above.

In addition, the laser generator 220 may also be processed using a single laser, but in some cases, the metal to be processed (ROL) varies in hardness for each type, and thus a different laser may be used.

In the present invention, as shown in Figure 3 so that all of these cases can be processed, assembling the disk 222 of the rotation angle is controlled to the unit body 220 rotatably, using a known means such as a motor It can be configured to rotate at an angle, and by installing a plurality of different laser generators 220, 220 ', 220 ", 220'" at a predetermined angle on the front of the disc 222 can be configured to be used as desired. have.

In this case, different laser generators 220, 220 ', 220 ", 220'" may have different outputs, and may have different types.

On the other hand, the present invention may be further provided with a cleaning housing 300 integrally with the processing housing 100 in front of the processing housing 100 in the form as shown in Figure 4 to improve the cleaning efficiency before the laser processing. That is, although not specifically illustrated, it is preferable that the processing housing 100 and the cleaning housing 300 are installed together on one base to be integrally configured to form one processing set.

In this case, the ceiling crane 400 may be installed to move the metal roll ROL, which is the object to be processed in the cleaning housing 300, to the processing housing 100 for laser processing.

This is because even the smallest metal rolls (ROLs) are heavy and difficult to lift by attraction.

In this case, since the washing housing 300 is formed in the same width and length as the processing housing 100, the washing housing 300 has a parallel structure as shown, but has an integral structure. For convenience, the internal structure will be drawn out separately and will be described supplementally.

That is, since the cleaning housing 300 should be able to inject the metal roll (ROL) is preferably formed in a rectangular box shape with an open top, the guide rail 310 is installed on the bottom surface, the guide rail 310 In this case, the washing movable chuck 320 is movable according to this, and the fixing fixing chuck 330 fixed to the bottom surface of the washing housing 300 is provided on the opposite side of the washing movable chuck 320.

In addition, the guide rail 310 is provided with at least one washing unit 340 that is movable along this, the washing unit 340 is between the washing moving chuck 320 and the washing fixing chuck 330 It may be moved, and may be installed alone or two at intervals.

If it is installed alone, the acetone washing unit 340 for removing oil, such as oil is used first, after which the acetone washing unit 340 is removed from the guide rail 310 for alcohol washing The washing unit 340 can be mounted and used.

In addition, only acetone washing unit 340 or alcohol washing unit 340 may be mounted. In addition, the number of the washing unit 340 may be increased or decreased as needed, the following description will be described based on two.

In this case, the two cleaning units 340 are made of the same structure and only the cleaning solution is different. Therefore, the same reference numerals will be used.

Of course, when using two at the same time, the acetone washing unit 340 moves ahead in the advancing direction, it can be arranged so that the alcohol washing unit 340 to follow the interval.

Here, the washing unit 340 is a U-shaped fixed frame 342 movable along the guide rail 310, as shown in Figure 5, and facing each other at the upper end of both sides of the fixed frame 342 A pair of roll frames 344a and 344b fixed in a vertical direction, a pair of guide rolls 346a and 346b fixed on the roll frames 344a and 344b, and a bottom of the fixed frame 342. A slit is formed on both sides of the washing solution tank 350 installed at the center of the surface and a position higher than the water level stored in the washing solution tank 350, and at least four installed on one side of the slit are rotated in engagement with each other. 354, an inlet roll 356 configured to be engaged with and rotated at least four of the slits opposite to the takeout roll 354 and the water storage portion of the cleaning tank between the takeout roll and the inlet roll. A central roll positioned at the center roll and the central roll 352 and the drawing roll 354 Four rolls constituting the cleaning cloth (PO) configured to be immersed in the cleaning solution while the guide roll 346a-the other guide roll 346b-the inlet roll 356 are wound in an endless track shape. It is configured to include a drive motor (M) connected to any one of.

Therefore, when the metal roll ROL, which is a processing target roll, enters and descends between the pair of guide rolls 346a and 346b using the ceiling crane 400, the cleaning cloth PO contacts the outer diameter of the metal roll ROL. It is wrapped around.

In this state, when the driving motor (M) is driven to wash the outer diameter of the metal roll (ROL) while the cleaning cloth (PO) is rotated in a caterpillar form, depending on the cleaning solution to remove the residues such as oil or alcohol The final wash will be performed.

In particular, by moving the cleaning unit 340 along the guide rail 310 by using a separate drive source in the state in which the drive motor (M) is rotated it is possible to wash the entire length of the metal roll (ROL).

In addition, since the entire outer diameter of the metal roll ROL needs to be washed, the chuck of either the washing mobile chuck 320 or the fixed fixing chuck 330 holding the metal roll ROL is rotated.

At this time, the rotational direction of the metal roll (ROL) is preferably rotated opposite to the rotational direction of the cleaning cloth (PO), but may be rotated in the same direction, in this case, the rotational speed and the cleaning cloth of the metal roll (ROL) If the rotational speed of PO is different from each other, cleaning by slip is possible.

In addition, the pair of guide rolls 346a and 346b may be configured to move in a direction facing each other using a pneumatic cylinder CY so as to maximize the washing area.

In addition, the cleaning solution tank 350 may further include a sweeper 358 spaced apart from the upper side of the inlet roll 356, the sweeper 358 is a cleaning cloth that is returned to the cleaning solution tank (350) PO) by squeezing out the cleaning solution attached to the cleaning cloth (PO) in a state containing contaminants to minimize the contamination of the cleaning solution in the cleaning solution tank (350).

In this case, a low container (not shown) may be provided directly below the sweeper 358.

On the other hand, when the cleaning cloth (PO) is rotated and washed in close contact with the outer circumferential surface of the metal roll (ROL) must maintain a close cleaning efficiency.

In other words, when the metal roll ROL is fixed to the chuck by pressing the cleaning cloth PO downward, the tension is maintained to some extent, but when there is no force to push the cleaning cloth PO upward while rotating, the cleaning cloth is rotated. Due to the (PO) lifting phenomenon, a gap with the surface of the metal roll (ROL) may occur, causing a poor cleaning.

For this reason, in the present invention, the upper end of the fixed frame 342 is divided into a lower fixed frame 342a and an upper fixed frame 342b in order to eliminate these problems.

Then, the lower fixing frame 342a to form a predetermined depth of the installation groove 342c at the upper surface so that the upper fixing frame 342b is fitted, but the predetermined length of the flow restriction groove around the installation groove 342c 342d is formed, and a hook-type locking portion 342f is further formed around the lower end of the upper fixing frame 342b so as to be fitted into the flow restricting groove 342d so that vertical flow is restricted. ) May be configured to always push up the bottom of the upper fixing frame 342b by embedding the coil spring 342e.

In this case, when the washing cloth (PO) is pressed while the heavy metal roll (ROL) is mounted, the washing cloth (PO) is always forced upward by the coil spring 342e, so Intimate contact with the outer surface makes it possible to improve the cleaning power.

In addition, as illustrated in FIG. 6, the housing cover 110 may further include a locking means for locking the processing housing 100 easily and quickly.

The locking means is a housing flange (F1) of the ')' shape having a rotating groove (H1) in the center of the width of the processing housing 100 is projected vertically, the housing flange (F1) to the rotating groove (H1). A flange pin hole (FPH) is formed in the lateral direction through the through hole, and a lower end of the rod-type fastener (ROD) having a thread is formed at the upper end in the pivoting groove (H1), and a fastener pin hole at the lower end of the rod-type fastener (ROD). (RPH) is formed so that the fixing pin (PIN) penetrates the flange pin hole (FPH) and the fixing pin pin hole (RPH) to pin the rotatable in the pivoting groove (H1) rotatably pin, Fixing nut (RNT) is fastened to the upper end of the fixture (ROD).

In addition, a cover flange F2 having a fitting groove H2 formed in the same shape as the housing flange F1 protrudes from the center of the width of the housing cover 110.

Therefore, when the housing cover 110 is closed toward the processing housing 100 and the fixture ROD is rotated upward, the fixture ROD enters the fitting groove H2.

In this state, when the fixing nut (RNT) is tightened, the fixing nut (RNT) is tightly fixed to the cover flange (F2) toward the housing flange (F1) so that easy and quick fixing is possible without being easily separated. Done.

In addition, as shown in FIG. 7, the cleaning solution tank 350 should be detachably installed from the inner bottom surface (BOT) of the fixed frame 342 so that the whole solution can be easily and quickly worked when the solution is used. desirable.

To this end, fixed latches (FRT) are fixed to both side surfaces of the lower end of the cleaning solution tank (350), and the fixed latch (FRT) is a flow latch (MRT) rotatably connected about a hinge axis (RT), A torsion spring (TSP) fitted to the hinge shaft (RT) is provided between the fixed latch (FRT) and the floating latch (MRT) so that the floating latch (MRT) is elastically rotatable with respect to the fixed latch (FRT). The bottom surface (BOT) is provided with a stator (FFT) to rotate the flow latch (MRT) by pressing it to be automatically clamped to have a latch function can facilitate the desorption.

In addition, the cleaning solution tank 350 is composed of a tank box 350a having an open upper surface and a tank cover 350b sealing the open upper surface of the tank housing 350a to be fitted together. By having a tank cover 350b is configured to be separated.

This is not only for the replacement, separation, etc. of the central roll 352 embedded therein, but also to separate the cleaning cloth PO, and also enlarges the tank cover 350b when viewed in the short side direction. A slit through which the cleaning cloth PO can be drawn out is formed on the structure, and thus, even when only the tank cover 350b is assembled, the cleaning cloth PO is configured to have a structure that can automatically take out the cleaning cloth PO.

At this time, for convenience, the assembly of the tank cover 350b is simplified and schematically illustrated. However, the tank cover 350b should be configured so that the tank cover 350b is not easily separated by a known fixing structure.

As such, the present invention is not only improves the cleaning efficiency is possible by automatic cleaning, the embossing through the laser is accurate and easy to prolong the service life of the emboss directly on the surface of the metal roll (ROL) itself, Contributing to the formation of a fine embossed pattern has the advantage of improving the quality of the embossed product formed.
