In other words, copying techniques and acts for making printed materials. Since the original function of the printed matter is a visual transmission medium, printing is one of the communication means, and recently it is also used as a decoration means for the purpose of sensation and emotion reaction. In order to produce printed materials, typography, that is, cloning techniques for producing printed materials, is used. For printing, ink is applied to a certain plate surface, and the ink is transferred to other materials (mainly paper is used, but cellophane, polyethylene, vinyl, wood, glass, porcelain, aluminum, tin plate, etc.) to transfer text or pictures. It is a multi-copying technique. The purpose is to typeset a sentence by type or phototype, and to reproduce a picture or photo with a convex plate or offset plate, and reproduce it as much as possible with a convex plate or offset plate.

The printing range is very wide, ranging from back-to-back plate printing to high-speed rotation printing. In addition, today, according to the progress of the civilization of consumption, not only paper but also metal plates, as well as printing on transparent materials such as cellophane, are also popular. Printed products such as vinyl or cloth print patterns, tableware and furniture surface decoration, etc. This advanced. As a printing method, there are three types of conventional convex plates, flat plates, and concave plates. In addition, the use of stencil printing is increasing, and electrostatic printing is performed even without pressing force. The method has been invented and is in practical use.

The present invention is a pattern containing gold foil once more using a film containing gold foil in order to add additional splendor, beauty, and luxury after finishing printing that is already necessary for, for example, a logo, mark, or the like on a card or packaging among such printing. It has to do with printing.

Such printed matter is a small quantity of a large number of varieties, so it is often simple to work, but more preferably, it is preferable that the operation is performed automatically and continuously while being accurate.

The frame 110 is a combination of an input unit (not shown) that a user can input into the printing apparatus 100 and an output unit (not shown) that includes an image that can indicate an operation state, a work quantity, etc. to the user. desirable.

The work table 120 is provided in plural on the frame 110 (in this embodiment, arranged at eight equal intervals as shown in FIGS. 1 and 2), the central axis of the rotation radius of the work table 120 rotates (CL ) Are arranged at equal intervals to form a radial shape. The work table 120 is provided in a rectangular shape having a predetermined thickness, and is provided with a plurality of vacuum holes 123a for mounting and fixing an object to be printed on the upper plate surface. The vacuum hole 123a is coupled to the vacuum hole piping member 123b communicated in the branch pipe 185a to form a vacuum pressure from the vacuum pump 183.

Here, the vacuum unit 123 includes a vacuum hole 123a, a vacuum hole piping member 123b, a vacuum valve 123c, a vacuum destruction pipe 123d, and a vacuum destruction valve 123e.

The vacuum valve 123c opens or closes the vacuum hole 123a and the vacuum hole piping member 123b in communication with the vacuum pump 183, and the vacuum release valve 123e has a vacuum hole 123a and a vacuum valve 123c. ) To open or close the vacuum break pipe 123d that is branched between and connected to the outside air or capable of supplying low pressure air. Here, among the ends of the vacuum destruction pipe 123d, it is preferable that a filter or the like is coupled so that foreign matter does not flow in when the outside air is introduced into the vacuum hole 123a.

That is, the vacuum valve 123c is opened and the vacuum release valve 123e except for the work table 120 located on the discharge table 170 to form a vacuum on the work table 120 as shown in the lower table of FIG. ) Is closed so that a vacuum is formed in the vacuum hole 123a of the work table 120 to firmly fix the object to be printed on the work table 120.

On the other hand, in the discharge table 170 for separating the object from the work table, the vacuum valve 123c is closed and the vacuum release valve 123e is opened to separate the object from the work table 120 from which the printing operation of the work table 120 is completed. You can do it easily.

The paper feeder 130 loaded the object to be printed and grips and adsorbs the object to be placed, placed, and mounted on the work table 120, and at the same time, places the object to be placed on the work table 120 as accurately as possible. do. The paper feeder 130 captures an object to be printed on the uppermost layer loaded on the paper feeder 133 and the paper feeder 133 for loading the object to be printed, and a predetermined position to be placed on the work table 120. The first vision unit 135 which detects or calculates the first distortion information on whether it is rotated or twisted or not is distorted and adsorbs and grips the object to be printed on the uppermost layer loaded in the paper loading unit 133 to obtain the first vision unit ( It consists of a paper feed adsorption unit (137) for correcting the direction of the object to be printed by rotating the value corresponding to the first distortion information calculated in 135), and to position, seat, and mount the object on the work table (120).

The second vision unit 140 grasps information about the position of the object to be printed, which is supplied from the feeder 130 and fixed to the work table 120-information about how much it has been rotated than the set fixed position, and whether it is out of alignment. To this end, the second distortion information, which is captured by a camera or the like, is transmitted to the gold foil printing machine 150 of the next process or sent to a control unit (not shown) to control the gold foil printing machine 150 to move and rotate.

The first vision unit 135 and the second vision unit 140 are sequentially present because the first vision unit 135 schematically and more precisely places the printed object on the work table 120. That is, since the process of rotating, moving, and seating an object to be printed on the feeder 130 is complicated and the distance to be moved is long, an error may occur even if the position of the object to be printed is corrected according to the first distortion information. There is high concern. On the other hand, the object to be mounted on the workbench 120 in the feeder 130 is firmly adsorbed by vacuum to the workbench 120, and only rotates from the feeder 130 side to the second vision unit 140, so that the worktable ( Since the object to be printed hardly moves on 120), the position of the object to be printed can be more accurately identified in the next process.

Therefore, it is preferable that the imaging resolution, detection capability, etc. of the second vision unit 140 is more precise and accurate than that of the first vision unit 135.

Gold foil printing machine 150, as shown in Figures 3 and 4, is supported on the work table 120, the 'X' axis direction, 'Y' axis direction is movable in the two-axis moving part 152 and the mold 154 and a film winding take-off unit 155 for winding and unwrapping a film, a printing machine lifting unit 153 for descending and elevating the film winding take-off unit 155, and a mold rotating member 156 for rotating the mold 154 Is made of

The two-axis moving unit 152 moves the configuration including the printing elevator unit 153 in a two-dimensional manner by a known method such as an LM guide or a ball screw that moves the combined configuration in the X-axis and the Y-axis. The position of the mold 154 may be corrected in response to the second distortion information provided by the vision unit 140.

The mold 154 is stamped on the lower side of the set pattern and is heated by a heating member 154a including a heater, so that the gold foil in the shape of the pattern is fused or printed on the printed object by using force and heat to press the printed object. It functions.

The film winding unit 155 includes an uncoiler 155a in which the gold-coated film can be wound and unwound, and a coiler 155b for winding the film recovered and used as a pattern printed in the mold 154 as a space. , Mold 154 is made of a mold guide roller () to guide the film from both sides. It is preferable that the film winding-out unit 155 has a function including a tensioner 155b1 for providing tension to a film, which is a known normal function.

The mold rotation member 156 may rotate the mold 154 about the 'Z' axis in order to correct the second distortion degree provided by the second vision unit 140.

Of course, the gold foil printer 150 may be provided as one, but it may be provided in plural, and multicolor to multi-color printing in which multiple colors or shapes are sequentially printed is also possible. When the gold foil printer 150 increases, it is preferable to increase the rotation radius of the work table 120 to facilitate the arrangement.

The clean roller 160 is provided at the front end of the discharge table 170 and the roller member 163 that presses or contacts the surface of the printed object to be fixed fixed to the upper surface of the table 120 while the work table 120 rotates, The roller member 163 is coupled to the roller driving unit 167 and the roller driving unit 167 to provide power to the roller member 163 to move forward and backward to move toward the work table 120, and the roller member 163 is moved forward and backward. It is made of a roller arm 165 to guide as much as possible.

In the clean roller 160, the roller driving unit 167 is operated while the object to be printed is fixed on the work table 120, as necessary, so that the roller member 163 is advanced by the roller arm 165 ('B' in FIG. 6). Reference), while reversing (refer to 'A' in FIG. 6), it is also possible to remove foreign substances, film residues, and the like present on the surface of the printed object.

In the discharge table 170, a vacuum is released to separate the object to be fixed to the work table 120, and the object to be fixed to the work table 120 corresponds to the paper feed adsorption section 137 of the tray 130. It moves to the discharge loading part (not shown) through the discharge adsorption part (not shown) to load the printed object on the gold foil printer 150. The outlet 170 is the same structure except for the feeder 130 and the first vision unit 135, so a detailed description is omitted.

As shown in FIG. 7, the vacuum piping module 185 includes a branch pipe 185a, a vacuum rotary joint 185b, and a buffer member 185c. The branch pipe 185a is a branch branched from each vacuum pipe module 185 to each vacuum portion 123 so as to be coupled with the vacuum portion 123. The vacuum rotary joint 185b is rotatably coupled to the fixed vacuum pump 183 and the pump vacuum pipe 183a.

The shock absorbing member 185c is provided with various types of shock absorbing means including a flexible hose and a rubber hose capable of buffering vibrations and shocks generated from the upper side of the vacuum rotary joint 185b so as not to be transmitted to the vacuum rotary joint 185b. The vacuum pressure generated by the vacuum pump 183 can be stably maintained even by external shock or vibration.

The operation method of the printing apparatus 100 according to the present invention having such a configuration will be described in detail with reference to FIG. 8 as follows.

First, when power is applied to the printing apparatus 100, each component prepares for operation. For example, the vacuum pump 183 is operated to form a vacuum on the work table 120 (S211), and although not shown, the heating member 154a including a heater is operated so that the mold 154 is heated. Here, if necessary, the vacuum pressure acting on the vacuum pump 183, the temperature of the mold 154, and the like can be controlled by the printing apparatus 100 so that it can be operated only when it is within a set range. have. That is, when the set vacuum pressure is not formed or the temperature of the mold 154 is not the set temperature, it is preferable that the printing apparatus 100 is not operated until the set vacuum pressure is formed.

As described above, the eight work tables 120 according to the present invention are rotated and use a fixed vacuum pump 183 to form a vacuum on the rotating work table 120 to form a more stable vacuum. A vacuum rotary joint 185b, a buffer member 185c, and the like are required.

When the operating apparatus is satisfied and the printing apparatus 100 is operated, the printed object loaded on the paper feed unit 133 of the paper feeder 130 is photographed by the first vision unit 135 including the camera. As a result of the imaging, the first distortion unit 135 detects the first distortion degree, which is information on the rotation or misalignment of the object to be printed at a predetermined position and an angle (S210). Next, the substrate to be sensed by the first vision unit 135 is adsorbed (S213) using, for example, an adsorbing plate (not shown) in which vacuum is applied, and the object to be rotated in response to the information of the first distortion level. The object to be printed is placed in a set position through correction such as prescribing, and the object to be printed is mounted (positioned) on the work table 120 (S215). The object to be printed on the work table 120 is fixed to the upper plate surface of the work table 120 by the vacuum pressure generated in the vacuum section 123 including the vacuum hole 123a.

Next, the work table 120 is rotated to the next step (in the present invention, eight work tables are radially arranged at equal intervals, as in FIGS. 1 and 2, and one step is 45, which is 1/8 of the 360 degree with respect to the central axis) Rotational movement (hereinafter referred to as 'S310'). For convenience of explanation, the state in which the work table 120 is located on the feeder 130 is referred to as a 'first step', and in the counterclockwise direction of FIG. 2, the 'second step', ..., the work table 120 on the discharge table 170 ) Will be referred to as the 'eighth step'.

When the work table 120 rotates and moves in the 'second step' that is the second vision part 140, the sensing means including the camera of the second vision part 140 captures the work object fixed to the work object 120. Or, it detects the second distortion degree of how much it is rotated and twisted in preparation for the set exact position (S223).

Then, the work table 120 is rotated another step (S310) to be located in the 'third step'.

When the work table 120 reaches the 'third step' which is the position of the gold foil printer 150, the work object 120 fixed to the work table 120 is referenced to correct the second distortion degree of the work object provided by the second vision unit 140. As shown in FIGS. 3 and 4 with respect to the workbench 120 where the two-axis moving part 152 of the gold foil printing machine 150 supports it, it moves in the 'X' axis and the 'Y' axis direction at the same time, or Subsequently, the mold 154 is rotated with respect to the 'Z' axis direction with respect to the two-axis moving part 152 to the printing elevator part 153.

After the second distortion degree is corrected through this process (S231), the printing lift unit 153 lowers the film of the mold 154 and the film take-off unit 155 (S233).

The lowered mold 154 presses the film toward the object to be printed and applies heat to fuse or print the patterns set in the mold on the object to be printed (S235). Here, the object to be printed is generally engraved with characters, images, and the like, which provide necessary information, and in the printing apparatus 100 according to the present invention, it is common to add luxurious and elegant images or patterns, such as silver foil, including gold foil.

Next, while the mold 154 and the film are raised (S237) by the printing elevator unit 153, the film on which the pattern is printed on the object to be printed by the mold 154 is a coiler 155b in a state where the pattern is spaced. As the roll is rolled, the new film is released from the uncoiler 155a one pitch at a time and positioned at the lower side of the mold 154 (S239), while maintaining the lifted state until the next work table 120 rotates and moves. The same process is repeated.

On the other hand, in the gold foil printer 150, the work table 120 in which printing supports the object to be printed is rotated to move to the next step, the 'fourth step' (S310). In the present invention, since the gold foil printer 150 is arranged to perform two-degree printing, no process is performed in the 'fourth step', but a process of determining whether to perform multicolor printing is performed (S240). As a result of the determination, in the case of performing multi-color printing (S243), the steps S231 to S237 described above are sequentially repeated in the second gold foil printer 150 in the 'fiveth step' by rotating once more (S310).

If it is determined that multicolor printing is to be performed after printing on the first gold foil printer 150 (S240), if multicolor printing is not performed (S245), the object to be printed on the work table 120 is sequentially processed through the 'fourth step' without any printing process. After the 'Fifth Step' and 'Fifth Step', the rotational movement (S310) is performed to the 'seventh step' where the discharge stand 170 is located.

Here, in the process of rotating from the 'sixth step' to the 'seventh step', the clean roller 160 provided to rotate while elastically pressing the upper side of the object to be printed is passed through the clean roller 160. The roller member 163 of the clean roller 160 rotates while pressing the surface of the object to be printed, and in this process, impact, pressure, and separation in the process of printing on the gold foil printer 150 such as dust on the object to be printed Foreign matter, film residue, etc., generated around the printed pattern generated by the back are attached to the roller member 163 and removed (S250).

The 'seventh step' destroys the vacuum to separate the object to be fixed to the work table 120 (S263), and the object to be printed which is not fixed to the work table 120 is the feed adsorption part 137 of the feeder 130 It moves through the discharge adsorption unit (not shown) corresponding to the discharge loading unit (not shown), and then undergoes an discharge process in which the printed object is loaded in the gold foil printer 150 (S260).

Here, although one embodiment of the present invention has been described and described, it can be seen that a person having ordinary knowledge in the technical field to which the present invention pertains can modify the present embodiment without departing from the principles or spirit of the present invention. will be. The scope of the invention will be defined by the appended claims and their equivalents.
