Disclosure of the invention

In order to perform precise printing, it is necessary to synchronize the rotation angle of the roller transfer cylinder and the relative translation position of the roller transfer cylinder with respect to the master plate and the work plate.

When the translation of the master plate / work plate and the roller transfer cylinder is performed by the rack and pinion mechanism, the synchronization accuracy depends on the pitch accuracy of the rack tooth profile, and adjustment is difficult.

[0004] On the other hand, a method has been proposed in which the translation movement of the master plate and the work plate and the roller transfer cylinder is performed by an electric servo drive mechanism using a servo motor. However, the positioning accuracy of the electric servo type is small compared to the mechanical rigidity of the rack and pinion type, and the printing accuracy is greatly affected by disturbances such as friction. Here, the rigidity means a restoring force generated when the roller transfer cylinder is displaced by a unit angle. In the rack and pinion mechanism, it corresponds to the rigidity of the gear, and in the electric servo type, it corresponds to the position control gain.

In the electric servo type, the servo rigidity increases as the position control gain increases. Actually, the servo rigidity is about iZio to iZioo of the gear rigidity because of the delay of the position sensor and motor. It can only be done. Therefore, even with an electric servo, the improvement in accuracy is not so much desired. In addition, electric servos require high-precision servomotors, which increases the cost of the equipment.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a printing machine capable of performing precise printing by accurately positioning a plate-like body with respect to a roller. And

[0006] In order to solve the above problems, the printing press of the present invention employs the following means.

In other words, the printing press that works in the first aspect of the present invention includes a roller and a surface plate on which a flat plate-like body is provided, and the roller and the surface plate are relatively translated. In the printing machine that transfers ink between the roller and the plate-like body, a cylindrical contact portion that contacts the surface plate is provided at the end of the roller. Roller rotation angle adjusting means is provided for adjusting the rotation angle of the roller when the abutting portion is separated from the platen.

[0007] The cylindrical contact portion provided at the end of the roller and the surface plate come into contact with each other, so that the cylindrical contact portion can roll with respect to the surface plate without looseness, and the rotation angle of the roller is accurate. To be determined. Furthermore, even if there is a relative deviation between the translational position of the roller and the rotation angle of the roller, the deviation is absorbed by utilizing the restoring force of the surface of the cylindrical contact portion that is generated with respect to this deviation. can do.

[0008] When the cylindrical contact portion is separated from the surface plate, the rotation angle of the aperture can be changed regardless of the surface plate. According to the roller rotation angle adjusting means, an appropriate roller rotation angle can be set before the cylindrical contact portion comes into contact with the surface plate, so that high-precision printing is realized.

[0009] As long as the surface plate and the roller relatively translate, the surface plate may be a type in which the roller is translated without translation, and the roller is not translated. The board may be moved in translation. Of course, both the roller and the surface plate may be translated.

[0010] Typically, examples of the plate-like body include a relief master plate having a reversal pattern and a work plate serving as a printed material such as a glass substrate. The cylindrical abutting portion is typically made of metal, but in order to make it easier to deform, it is easier to deform than metal! /, And members such as urethane may be lined!

[0011] In addition, a printing machine according to the second aspect of the present invention includes a roller and a surface plate on which a flat plate-like body is installed, and relatively connects the roller and the surface plate. In a printing machine that transfers ink between the plater and the plate-like body while being translated, a flat contact portion that contacts the end portion of the roller is provided at the end portion of the surface plate. And a roller rotation angle adjusting means for adjusting the rotation angle of the roller when the roller is separated from the planar contact portion.

[0012] When the flat contact portion provided at the end of the surface plate comes into contact with the roller, the roller rolls with respect to the flat contact portion, so that the rotation angle of the roller is accurately determined. . Furthermore, even if there is a relative deviation between the translational position of the roller and the rotation angle of the roller, the deviation can be reduced using the restoring force of the surface of the planar abutment that is generated with respect to this deviation. Can be absorbed.

[0013] When the roller does not contact the flat contact portion, the rotation angle of the roller can be changed regardless of the surface plate. According to the roller rotation angle adjusting means, an appropriate roller rotation angle can be set before the roller abuts on the planar abutting portion, so that highly accurate printing is realized.

[0014] As long as the surface plate and the roller are relatively translated, the surface plate may be a type in which the roller is moved without translation, and the roller is not moved in translation. The board may be moved in translation. Of course, both the roller and the surface plate may be translated.

[0015] Typically, examples of the plate-like body include a relief master plate having a reversal pattern and a work plate serving as a printed material such as a glass substrate.

The flat contact portion is typically made of metal, but in order to be easily deformed, it can be deformed more easily than metal! /, And a member such as urethane may be lined!

[0016] Further, the printing machine that is effective in the first aspect and the second aspect includes a carriage that holds the roller in a rotatable manner and moves in translation with respect to the surface plate, and the surface plate. And a linear motor that drives the carriage with respect to the main body to be supported. [0017] Since the carriage that rotatably holds the roller is driven by a linear motor and is directly driven without using a panel element such as a ball screw, there is no lost motion (no play) Operation can be realized, and highly accurate positioning is possible. Further, the linear motor may be configured to drive both side portions of the carriage.

[0018] Further, the printing machine according to the third aspect of the present invention includes a roller and a surface plate on which a flat plate-like body is installed, and relatively connects the roller and the surface plate. In a printing machine that transfers ink between the mouth roller and the plate-like body while being translated, the roller has a front end of the plate-like body where the roller first contacts the plate-like body. It is softly supported to follow the club.

[0019] Since the roller is softly supported so as to follow the front end portion of the plate-like body, even if the installation direction of the plate-like body is inclined or the roller has a bowing error, These errors can be corrected.

As long as the surface plate and the roller are relatively translated, the surface plate may be a type that translates the roller without translation, and the roller translates the surface without translation. It is good also as a form to move. Of course, both the roller and the surface plate may be translated.

Typical examples of the plate-like body include a relief master plate having a reversal pattern and a work plate to be printed such as a glass substrate.

[0020] Further, the printing machine according to the fourth aspect of the present invention includes a roller having a cylindrical contact portion provided at an end portion thereof, a carriage that rotatably holds the roller, and a flat plate-like plate And a main body having a planar abutting portion that abuts against the cylindrical abutting portion, and the carriage is brought into contact with the planar abutting portion. In the printing machine in which ink is transferred between the roller and the plate-like body while translationally moving with respect to the main body, the carriage is driven by the rotational force of the roller.

[0021] Since the carriage is moved in translation by the rotational force of the roller, the translation position of the roller with respect to the plate-like body and the rotation angle of the roller can be controlled at the same time, and highly accurate synchronous driving can be realized. I'll do it.

Moreover, since a mechanism for driving the carriage in translation is not required, the configuration is simplified. [0022] According to the printing machine of the present invention, the following effects can be obtained.

By bringing the cylindrical abutting portion provided at the end of the roller into contact with the surface plate, the cylindrical abutting portion can roll without play against the surface plate, and the rotation angle of the roller is accurately determined. It is done. Furthermore, even if there is a relative deviation between the translational position of the roller and the rotation angle of the roller, the deviation is absorbed by utilizing the restoring force of the cylindrical contact portion surface that is generated with respect to this deviation. be able to. As described above, highly accurate printing is possible.

[0023] Further, by bringing the flat contact portion provided at the end of the surface plate into contact with the roller, the roller rolls without play against the flat contact portion. Is accurately determined. Furthermore, even if there is a relative deviation between the translational position of the roller and the rotation angle of the roller, the deviation is absorbed by using the restoring force of the surface of the flat abutting portion generated with respect to this deviation. can do. As described above, highly accurate printing is possible.

[0024] Further, since the roller is supported flexibly so as to follow the front end portion of the plate-like body, the installation direction of the plate-like body is inclined or the roller has a bowing error. Even these errors can be corrected.

[0025] Further, since the carriage is moved in translation by the rotational force of the roller, the translation position of the roller with respect to the plate-like body and the rotation angle of the roller can be controlled at the same time, and highly accurate synchronous driving can be realized. .

BEST MODE FOR CARRYING OUT THE INVENTION

[0027] Embodiments according to the present invention will be described below with reference to the drawings.

[0028] [First embodiment]

A printing press that works according to the first embodiment of the present invention will be described.

FIG. 1 schematically shows the entire printing machine 1.

The printing press 1 is printed in four colors, R (red), G (green), B (blue), and BK (black), and includes four roller transfer cylinders 4 corresponding to each color.

A table 5 is fixed to the main body 3 of the printing machine 1, and a master plate (plate-like body) 7 and a work plate (plate-like body) 8 are placed on the table 5. .

The master plate 7 has a flat plate shape and is a relief plate on which a reverse pattern of the pattern printed on the work plate is formed. The master plate 7 is fixed on the surface plate 21. The master plate 7 removes the ink corresponding to the reverse pattern by transferring it from the roller transfer cylinder 4 on which the ink is held as a whole.

The work plate 8 is a substrate to be printed which is a flat glass substrate, and ink corresponding to the printing pattern is transferred from the roller transfer cylinder 4. The work plate 8 is fixed on the surface plate 21.

[0031] The roller transfer cylinder 4 is a blanket cylinder having a water-repellent blanket wound around its outer periphery. The roller transfer cylinder 4 is held on the carriage 10 in a state where four rollers are arranged in parallel in the translation direction A.

Each of the roller transfer cylinders 4 is provided with a rotation servomotor (roller rotation angle adjusting means) M (see FIG. 2) for determining the rotation angle. The rotation servo motor M is configured such that its rotation angle and rotation speed are controlled by a control unit (roller rotation angle adjusting means) not shown.

Cylindrical bearer rolls (cylindrical contact portions) 11 are provided at both ends of the roller transfer cylinder 4 (see FIG. 2). The bearer roll 11 is typically made of metal. However, in order to increase the restoring force at the time of contact, a resin such as urethane may be lined.

As shown in FIG. 2, the bearer roll 11 is provided at a position where it abuts on both sides of the surface plate 21. It is.

The cart 10 includes a translation servomotor (not shown), and is translated on the rail 6 of the main body 3 by the translation servomotor. As a result, the roller transfer cylinder 4 is translated relative to the master plate 7 and the work plate 8.

[0033] The printer 1 having the above-described configuration operates as follows.

First, ink of each color is applied to each of the roller transfer cylinders 4 by an ink application device (not shown).

Next, the carriage 10 is translated relative to the main body 3. At this time, each roller transfer cylinder 4 is in a floating state in which the upper surface force of the surface plate 21, the master plate 7 and the work plate 8 placed on the table 5 is separated. Accordingly, the roller transfer cylinder 4 can be idled, and the rotation angle is adjusted by the servo motor for rotation in this state.

When the carriage 10 approaches the first master plate 7, the roller transfer month 4 corresponding to the color of the master plate 7 is lowered by an elevator (not shown), and the bearer roll 11 and the surface plate 21 come into contact with each other. The bearer roll 11 is always in contact with the side of the surface plate 21 while the roller transfer cylinder 4 passes over the surface plate 21.

Thereafter, the roller transfer cylinder 4 comes into contact with the master plate 7, and the reverse pattern ink corresponding to the relief formed on the master plate 7 is transferred to the master plate 7 side and removed.

After the ink corresponding to the reversal pattern is removed by the master plate 7, the roller transfer month 4 is raised and the upper surface force of the master plate 7 is also separated. In this state, the rotation angle of the roller transfer cylinder 4 is adjusted again by the servo motor for rotation.

When the carriage 10 approaches the next master plate 7, another roller transfer month 4 corresponding to the color of the master plate 7 is lowered and transferred in the same manner as described above.

The roller transfer cylinder 4 that has been transferred to and from the master plate 7 of each color in this way finally moves down toward the work plate 8 and comes into contact with the upper surface of the work plate 8 to thereby move the roller transfer cylinder 4 onto the roller transfer cylinder 4. The pattern is transferred to the work board 8. Also at this time, the bearer roll 11 comes into contact with the surface plate 21.

In this way, the ink for four colors is transferred to the work plate 8.

[0037] According to the printing machine 1 of the present embodiment, the bearer roll 11 provided on the roller transfer cylinder 4 is attached to the surface plate 2. By bringing the roller transfer cylinder 4 into contact with 1, the roller transfer cylinder 4 can be rolled with respect to the surface plate 21 with no play, and the rotation angle of the roller is accurately determined. Furthermore, the synchronization accuracy can be improved by utilizing the restoring force of the surface of the roller roll 11 generated with respect to the relative deviation between the translation position of the carriage 10 and the rotation angle of the roller transfer month 4. That is, even if a relative deviation between the translation position of the carriage 10 and the rotation angle of the roller transfer cylinder 4 occurs, the deviation can be absorbed by the restoring force accompanying the deformation of the bearer roll 11 surface. This achieves high-precision printing.

As shown in FIG. 3, instead of the structure in which the roller roll 11 is provided with the roller roll 11, a structure in which bearer rails (planar contact portions) 12 are provided on both sides of the surface plate 21 may be employed. Even in such a configuration, the restoring force of the bearer rail 12 can be utilized by bringing the non-imaged portion 11 ′ located at both ends of the roller transfer cylinder 4 into contact with the bearer rail 12.

[Modification]

A configuration as shown in FIGS. 4 and 5 may be adopted for the drive device for moving the carriage 10 in translation.

As shown in FIGS. 4 and 5, a linear motor 15 is provided to translate the carriage 10 in translation. The linear motor 15 includes a coil slider 15a and permanent magnets 15b facing the coil slider 15a and linearly provided on both sides of the main body 3. The coil slider 15a is provided at the lower end of the bracket 10a projecting downward from the sides on both sides of the carriage 10. A power source current (not shown) is passed through the coil slider 15a, whereby the polarity of the coil slider 15a is sequentially reversed. In this way, the linear motor 15 is arranged so as to give a driving force to both sides of the carriage 10, and each roller transfer cylinder 4 is provided with a rotation servo motor for adjusting the rotation angle. (Not shown).

If such a linear motor 15 is used, the carriage 10 can be directly driven without using a panel element such as a ball screw. Therefore, it is possible to realize an operation without a lost motion (no looseness), and high-precision printing is possible.

[0040] [Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, description of parts common to the printing press 1 described in the first embodiment will be omitted, and different parts will be described.

FIG. 6 shows a plan view of the main part of the printing press 1.

In the figure, for ease of understanding, only one roller transfer cylinder 4 is shown. In the case of multi-color printing, a plurality of roller transfer cylinders 4 are used as in the first embodiment.

The roller transfer cylinder 4 is flexibly supported by the carriage 10. Specifically, when the roller transfer month 4 is brought into contact with the front end F (downward in the figure) F of the master plate 7 or work plate 8 placed on the table 5, the inclination angle of the front end F is set. The support structure can be deformed to follow. That is, the support structure can be deformed so as to follow the angle Θ formed by the direction orthogonal to the extending direction of the table 5 and the front end F of the master plate 7 or the work plate 8.

As described above, since the roller transfer cylinder 4 is flexibly supported, when the installation direction of the master plate 7 and the work plate 8 is inclined, or as shown by the two-dot chain line in FIG. Even if the direction in which the central axis of the roller transfer cylinder 4 faces in the direction perpendicular to the translation direction A (when the roller transfer cylinder 4 has a skewing error), the master plate 7 and the work plate When it comes into contact with the front end F of 8, it deforms to follow the front end F by its contact force.

In FIG. 7, for ease of understanding, the angle Θ formed by the direction perpendicular to the extending direction of the table 5 and the front end F of the master plate 7 or the work plate 8 is emphasized and increased. 10 " ⁵ ~: It is preferable to have a flexible structure that can tolerate an inclination of about LO ^_6 rad.

[0042] [Third embodiment]

A printing press that works according to the third embodiment of the present invention will be described. In the present embodiment, description of portions common to the printing press 1 described in the first embodiment is omitted as appropriate. The present embodiment is greatly different from the first embodiment in the configuration for driving the carriage 10 and the configuration of the bearer rail 12.

In FIG. 7, the entire printing press 1 is schematically shown.

As in the first embodiment, the printing machine 1 is printed in four colors, R (red), G (green), B (blue), and BK (black), and four roller transfers corresponding to each color. It has a torso 4

[0043] A table 5 is fixed to the main body 3 of the printing machine 1, and a master is placed on the table 5. A plate (plate-like body) 7 and a work plate (plate-like body) 8 are placed.

[0044] The roller transfer cylinder 4 is a blanket cylinder having a water-repellent blanket wound around the outer periphery thereof. Cylindrical bearer rolls (cylindrical contact portions) 11 are provided at both ends of the roller transfer cylinder 4 (see FIG. 8). Bearer roll 11 is made of metal.

Each of the roller transfer cylinders 4 is provided with a servo motor (not shown) that determines the rotation angle and performs translational motion. The roller transfer cylinder 4 is held by the carriage 10 in a state where four rollers are arranged in parallel in the translation direction A.

The carriage 10 is translated on the main body 3 by a servo motor provided on the roller transfer cylinder 4. As shown in FIG. 9, linear guides 13 are provided below both sides of the carriage 10, and the carriages 10 translate linearly with respect to the main body 3 by the linear guides 13.

[0045] On both side portions of the main body 3, planar bear rails (planar contact members) 12 are provided in the translational direction A, that is, the extending direction of the main body 3 (see FIG. 8). The bearer rail 12 is made of metal. This bearer rail 12 abuts on a bearer roll 11 provided on the roller transfer cylinder 4.

As shown in FIG. 10, the roller transfer cylinder 4 comes in close contact with each other so that the ink transfer is performed between the corresponding master plate 7 or work plate 8 and the roller transfer cylinder 4, and the ink is transferred. The bearer rail 12 is provided with a height difference so that the roller transfer cylinder 4 is separated from the master plate 7 or the work plate 8 after the transfer. That is, the bearer roll 11a rolls on the bearing rail 12A so that the roller transfer cylinder 4a approaches the corresponding master plate 7a and separates from the non-corresponding master plate 7b! /, The

FIG. 11 shows two bearing rails 12A, B corresponding to different colors. When the bearer rails 12A and 12B pass over the master plate 7 different from the corresponding color, the separation portion 12c through which the roller transfer cylinder 4 passes without contacting the master plate 7 and the roller transfer cylinder 4 And a transfer portion 12a for contacting the master plate 7 of the corresponding color. In other words, the height H of the separation portion 12c is made larger than the height h of the transfer portion 12a.

A connecting portion 12b that smoothly connects the separating portion 12c and the transfer portion 12a is provided between the separating portion 12c and the transfer portion 12a so that the roller transfer cylinder 4 can be moved up and down smoothly. It has become. As described above, the bearer roll 11 always comes into contact with the bearer rail 12 regardless of whether the roller transfer cylinder 4 approaches the master plate 7 or not.

[0048] The printer 1 having the above-described configuration operates as follows.

Next, the servo motor of the roller transfer cylinder 4 is driven to move the carriage 10 in translation relative to the main body 3. At this time, each roller transfer cylinder 4 is in a floating state in which the upper surface force of the master plate 7 or work plate 8 placed on the table 5 is separated by a bearer rail 12 (see FIGS. 10 and 11) having a height difference. It is said that.

When the carriage 10 approaches the first master plate 7, the roller transfer month 4 corresponding to the color of the master plate 7 is lowered according to the shape of the rail rail 12 and comes into contact with the master plate 7. As a result, the ink of the reverse pattern corresponding to the relief formed on the master plate 7 is transferred to the master plate 7 side and removed. After the ink corresponding to the reversal pattern is removed from the roller transfer cylinder 4, the roller transfer cylinder 4 is raised according to the shape of the barrier rail 12 and separated from the upper surface of the master plate 7.

When the carriage 10 approaches the next master plate 7, the roller transfer cylinder 4 corresponding to the color of the master plate 7 descends according to the shape of the rail rail 12 and is transferred in the same manner as described above.

The roller transfer cylinder 4 that has been transferred to and from the master plate 7 of each color in this way finally moves down toward the work plate 8 and comes into contact with the upper surface of the work plate 8 to thereby move the roller transfer cylinder 4 onto the roller transfer cylinder 4. The pattern is transferred to the work board 8.

In this way, the ink for four colors is transferred to the work plate 8.

As described above, according to the printing machine 1 of the present embodiment, the roller transfer cylinder 4 is translated along with the carriage 10 by the servo motor that rotationally drives the roller transfer cylinder 4, so that the master plate 7 of the roller transfer cylinder 4 or The translation position with respect to the work plate 8 and the rotation angle of the roller transfer cylinder 4 can be controlled at the same time, and high-accuracy synchronous drive can be realized.

In addition, since a mechanism for driving the carriage 10 in translation is not required, the configuration can be simplified.
