BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment Hereinafter, a first embodiment of a printing press according to the present invention will be described with reference to the drawings. Here, FIG. 1 to FIG. 4 are diagrams showing a first embodiment of the present invention.

  As shown in FIG. 1, the printing machine includes a frame 55, a printing plate surface plate 56 placed on the frame 55 and on which the printing plate 61 is placed, a work plate 62 and a work plate 62. And a work surface plate 57 to be placed.

  In addition, since the uniformity of a film | membrane is requested | required in the organic layer used for organic EL and an organic thin-film transistor (organic TFT), it is preferable that the printing press by this Embodiment is used when forming an organic layer. For this reason, it is preferable that the workpiece | work 62 contains the board | substrate for mounting the organic layer used for organic EL. As such a workpiece 62, for example, a glass substrate (nothing is placed), a glass substrate on which some organic layers used for organic EL or organic TFT are already placed, an insulating layer, and Some glass substrates on which electrodes (such as ITO) have already been placed, film substrates on which nothing is placed, and some organic layers used in organic EL and organic TFTs have already been placed A film substrate on which a film substrate, an insulating layer, and an electrode (such as ITO) are already mounted can be used.

  Examples of the organic layer placed on the workpiece 62 such as a glass substrate or a film substrate include a light emitting layer 72, an electron transport layer 71, an intermediate layer 74, a hole injection layer / hole transport layer 75, and the like. (See FIG. 14). Here, the light emitting layer 72 has a thickness of about 80 nm, the intermediate layer 74 has a thickness of about 20 nm, and the hole injection layer / hole transport layer 75 has a thickness of about 80 nm.

  Hereinafter, a case where a glass substrate is used as the workpiece 62 and a film made of an organic layer constituting the organic EL is formed on the glass substrate 62 will be described as an example.

  As shown in FIG. 1, a rack 35 is provided on the side of the frame 55 via a rack base 30. As shown in FIGS. 1 and 2, a blanket unit 40 that can move in the vertical direction with respect to the frame 55 and can run on the frame 55 is provided above the frame 55. The blanket unit 40 includes a blanket cylinder 41 and a blanket 42 wound around the blanket cylinder 41. The blanket cylinder 41 of the blanket unit 40 is provided with a pinion 45 that can be engaged with the rack 35.

  As shown in FIGS. 1 and 2, a printing plate inclined surface 56 a is formed at the downstream end of the printing plate surface plate 56 so as to descend from the other part of the printing plate surface plate 56 and be inclined. . In the present application, the “downstream side” means the downstream side in the traveling direction of the blanket unit 40.

  As shown in FIGS. 1 and 2, with respect to the blanket unit 40, on the moving direction side (right side in FIG. 1) of the blanket unit 40, a discharge unit 66 that discharges ink (paint) and the discharge unit There is provided a doctor 65 that conveys the ink ejected from 66 and fills the hole 61a (see FIG. 2) having a predetermined pattern formed on the printing plate 61 with the ink.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, the blanket unit 40 is positioned below, and the pinion 45 and the rack 35 are engaged (engagement step) (see arrow A in FIG. 3A).

  Next, when the blanket cylinder 41 is rotated (see arrow B in FIG. 3A), the pinion 45 is rotated on the rack 35 and the blanket unit 40 is moved in the horizontal direction (see FIG. 1). Rightward) (horizontal direction moving step) (see arrow C in FIG. 6B).

  By moving the blanket unit 40 in the horizontal direction with respect to the frame 55 in this manner, first, ink (paint) discharged from the discharge portion 66 is carried by the doctor 65 and the ink is placed on the printing platen 56. It flows into and fills the holes 61a forming a predetermined pattern of the placed printing plate 61. Next, the ink flowing into the hole 61 a in this way is received by the blanket 42 of the blanket unit 40.

  Thereafter, the blanket unit 40 is formed on the downstream end portion of the printing plate surface plate 56, passes through the printing plate inclined surface 56a inclined downward from the other portions of the printing plate surface plate 56, and then on the workpiece surface plate 57. The glass substrate 62 is reached. Then, the ink received by the blanket 42 is transferred to the glass substrate 62 placed on the work surface plate 57.

  At this time, the printing plate inclined surface 56 a is lowered as compared with other portions of the printing plate surface plate 56. For this reason, it is possible to prevent an unexpected force from being applied to the rack 35.

  That is, since the printing plate inclined surface 56a is inclined as described above, the load applied to the blanket unit 40 can be gradually released, and eventually the load applied to the rack 35 is gradually released. Can do. Therefore, the rack 35 can be prevented from suddenly moving in the vertical direction with respect to the rack base 30 (the distortion of the rack 35 due to the force applied from the pinion 45 is prevented from being suddenly released. It is possible to prevent the rack 35 from being damaged by the reaction.

  When such a horizontal movement process is completed, the blanket unit 40 is positioned upward, and the engagement between the pinion 45 and the rack 35 is released (release process) (see arrow D in FIG. 3C). Thereafter, the blanket unit 40 is moved in the horizontal direction (left direction in FIG. 1) and returned to the original position (returning step) (see arrow E in FIG. 3C).

  By the way, although the printing plate inclined surface 56a was demonstrated using the aspect currently formed in the downstream edge part of the printing plate surface plate 56 by the above, it is not restricted to this.

  For example, the upstream end portion of the printing plate surface plate 56 may form a printing plate inclined surface that descends from the other part of the printing plate surface plate 56 and is inclined.

  However, in the aspect in which the downstream end portion of the printing plate surface plate 56 forms the inclined printing plate surface 56a that is inclined downward from the other portions of the printing plate surface plate 56, the load applied to the blanket unit 40 is gradually increased. Thus, the load applied to the rack 35 can be gradually released. For this reason, it is possible to prevent the rack 35 from suddenly moving in the vertical direction with respect to the rack base 30, and it is possible to prevent the rack 35 from being damaged by the reaction, which is preferable. In the present application, the “upstream side” means the upstream side in the traveling direction of the blanket unit 40.

  Further, for example, as shown in FIGS. 4A and 4B, the printing plate inclined surfaces 56a and 56b are formed in a portion other than the portion corresponding to the area where the hole 61a is disposed (the paint placement area IA). You may be made to do. 4A and 4B, the printing plate inclined surface 56b is formed at the upstream end portion of the printing plate surface plate 56, and the printing plate inclined surface 56a is formed at the downstream end portion.

In this way, by forming the printing plate inclined surface 56 a in a portion other than the portion corresponding to the paint placement area IA of the printing plate 61, the blanket 42 has time to apply a load to the blanket unit 40. It can be limited when contacting the paint placement area IA. For this reason, the time for which a load is applied to the blanket unit 40 can be minimized, and the blanket unit 40 can be further reliably prevented from being distorted. 4A is a side view of the printing platen plate 56 in such an embodiment, and FIG. 4B is an upper plan view of the printing platen plate 56.

  By the way, in the above, the printing platen plate 56 which is arranged on the frame 55 and on which the printing plate 61 is placed, and the workpiece platen which is arranged on the frame 55 and on which the glass substrate (workpiece) 62 is placed. Although the embodiment using the gravure offset method has been described using a printing machine having both of the devices 57, the present invention is not limited to this, and a gravure direct method can also be used.

  For example, if the work 62 made of a film is used and this film is disposed on the surface of the blanket of the blanket unit, the work surface plate 57 described above becomes unnecessary.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment shown in FIGS. 5 to 8, a printing plate inclined surface 56 a that is inclined downward from the other part of the printing plate surface plate 56 is formed at the downstream end of the printing plate surface plate 56. Instead, a workpiece inclined surface 57a inclined downward from the other part of the workpiece surface plate 57 is formed at the downstream end of the workpiece surface plate 57, and the other configurations are shown in FIGS. This is substantially the same as the first embodiment shown in FIG.

  In the second embodiment shown in FIG. 5 to FIG. 8, the same parts as those in the first embodiment shown in FIG. 1 to FIG.

  As shown in FIGS. 5 and 6, in the present embodiment, a workpiece inclined surface 57 a is formed at the downstream end of the workpiece surface plate 57 so as to be inclined downward from the other part of the workpiece surface plate 57. Yes. For this reason, it is possible to prevent a sudden force from being applied to the rack 35 as in the first embodiment.

  That is, since the workpiece inclined surface 57a is inclined, the load applied to the blanket unit 40 can be gradually released, and consequently the load applied to the rack 35 can be gradually released. Therefore, the rack 35 can be prevented from suddenly moving in the vertical direction with respect to the rack base 30 (the distortion of the rack 35 due to the force applied from the pinion 45 is prevented from being suddenly released. It is possible to prevent the rack 35 from being damaged by the reaction.

  By the way, although it demonstrated using the aspect in which the workpiece | work inclination surface 57a was formed in the downstream end part of the workpiece surface plate 57 by the above, it is not restricted to this.

  For example, the upstream end of the work surface plate 57 may form a work inclined surface that is inclined downward from the other part of the work surface plate 57.

  However, in the aspect in which the downstream end portion of the work surface plate 57 forms a work inclined surface 57a that is inclined downward from other parts of the work surface plate 57, the load applied to the blanket unit 40 is gradually released. As a result, the load applied to the rack 35 can be gradually released. For this reason, it is possible to prevent the rack 35 from suddenly moving in the vertical direction with respect to the rack base 30, and it is possible to prevent the rack 35 from being damaged by the reaction, which is preferable.

  For example, as shown in FIGS. 7A and 7B, the workpiece inclined surfaces 57a and 57b are formed in portions other than the portion corresponding to the printing area PA of the glass substrate 62 to which ink is applied. Also good. 7A and 7B, a workpiece inclined surface 57b is formed at the upstream end portion of the work surface plate 57, and a workpiece inclined surface 57a is formed at the downstream end portion.

In this way, by forming the workpiece inclined surface 57a in a portion other than the portion corresponding to the printing area PA of the workpiece surface plate 57, the blanket 42 has a time during which the load is applied to the blanket unit 40. It can be limited when touching. For this reason, the time for which a load is applied to the blanket unit 40 can be minimized, and the blanket unit 40 can be further reliably prevented from being distorted. Incidentally, FIG. 7A is a side view of the work surface plate 57 in such an embodiment, and FIG. 7B is an upper plan view of the work surface plate 57.

  Note that the printing area PA of the glass substrate 62 described above corresponds to the paint placement area IA of the printing plate 61 shown in the first embodiment. That is, after the ink placed in the paint placement area IA having the hole 61 a of the printing plate 61 is received by the blanket 42 of the blanket unit 40, the ink is placed in the printing area PA of the glass substrate 62 on the work surface plate 57. Be transferred.

  By the way, as shown in FIG. 8, the work surface plate 57 is configured by a work main body portion 57p and a work inclined portion 57q connected to the work main body portion 57p and having an upper surface forming a work inclined surface 57a. It may be.

  In this manner, by providing the workpiece inclined portion 57q separately from the workpiece main body portion 57p, the workpiece inclined surface 57a having an appropriate inclination angle can be formed at an inexpensive price. That is, only a plurality of workpiece inclined surfaces 57a having different angles (the workpiece main body portion 57p can be used in common) are prepared, and are adjusted to various conditions such as the thickness and material of the workpiece 62 such as a glass substrate. Thus, it is possible to select an appropriate workpiece inclined portion 57q, and it is possible to form the workpiece inclined surface 57a having an appropriate inclination angle at an inexpensive price.

  In addition, the printing plate inclined surface which inclines by descending from the other part of the printing plate surface plate 56 to the downstream side end portion of the printing plate surface plate 56 by combining the second embodiment with the first embodiment. The workpiece inclined surface 57a may be formed at the downstream end of the workpiece surface plate 57 and inclined downward from the other parts of the workpiece surface plate 57.

  By the way, in the present embodiment, as in the first embodiment, not only the gravure offset method but also the gravure direct method can be used. That is, if the printing plate is disposed on the surface of the blanket of the blanket unit and a supply unit and a doctor for supplying ink to the printing plate are provided in the vicinity of the blanket, the printing plate surface plate 56 is not necessary.

Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment shown in FIG. 9, the rack 35 is movable in the vertical direction with respect to the rack base 30, and the rack 35 is perpendicular to the rack base 30 between the rack 35 and the rack base 30. A plurality of springs (elastic members) 11 that are biased upward are provided. Other configurations are substantially the same as those of the first embodiment shown in FIGS.

  In the third embodiment shown in FIG. 9, the same parts as those in the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 9, the rack 35 is movable in the vertical direction with respect to the rack base 30, and between the rack 35 and the rack base 30, the rack 35 is vertically above the rack base 30. A plurality of springs 11 are provided to urge toward.

  For this reason, even if the pinion 45 collides with the rack 35 in the vertical direction, the rack 35 can be elastically moved in the vertical direction with respect to the frame 55, and the pinion 45 vibrates in the vertical direction due to the impact of the collision. This can be prevented. As a result, it is possible to prevent the blanket unit 40 from vibrating in the vertical direction with respect to the glass substrate 62, and unevenness (the surface of the organic layer printed on the glass substrate 62 becomes uneven and the printing progresses). An organic layer having a uniform thickness without forming fine streaks (see FIG. 15) in a direction perpendicular to the direction (see 81a in FIG. 15) or an oblique direction (see 81b in FIG. 15). Can be generated. In addition, this step unevenness is formed when the thickness of the film printed on the workpiece is reduced.

  Further, since the plurality of springs 11 are provided, it is possible to uniformly disperse the impact on the rack 35 when the pinion 45 collides with the rack 35 in the vertical direction. For this reason, the organic layer which consists of a uniform film thickness can be produced | generated more reliably.

  Moreover, as shown in FIG. 9, the spring 11 is pressed against the rack 35 and attached by a spring load adjusting bolt (elastic force adjusting member) 11a. For this reason, the elastic force that acts on the rack 35 from the spring 11 can be adjusted by adjusting the tightening degree of the spring load adjusting bolt 11a. From this, the elastic force acting on the rack 35 from the spring 11 can be finely adjusted, and an organic layer having a uniform film thickness can be more reliably generated.

  Incidentally, as described above, when the rack 35 is movable in the vertical direction with respect to the rack base 30 and the spring 11 is provided between the rack 35 and the rack base 30, the blanket unit 40 is fixed to the printing plate. When leaving the board 56, the rack 35 may suddenly move with respect to the rack base 30, and the rack 35 may be damaged.

  That is, when there is no printing plate inclined surface 56a that is lowered and inclined at the downstream end of the printing plate surface plate 56 as in the prior art, the rack 35 suddenly moves up and down with respect to the rack base 30. There is a possibility that the rack 35 is damaged by the reaction.

  On the other hand, according to the present embodiment, as shown in FIGS. 1 and 2, the printing plate inclined surface 56 a that is lowered and inclined at the downstream end of the printing plate surface plate 56 is provided. The load applied to the blanket unit 40 can be gradually released, and consequently the load applied to the rack 35 can be gradually released. For this reason, it is possible to prevent the rack 35 from suddenly moving in the vertical direction with respect to the rack base 30, and it is possible to prevent the rack 35 from being damaged by the reaction.

  As shown in FIG. 10, a shock absorber (shock absorbing member) 15 that suppresses the rack from being rapidly pushed back by the elastic force of the spring 11 may be further provided below the rack 35. Further, in FIG. 10, the protruding portion 15a of the shock absorber 15 passes through the rack base 30 and is attached to the rack 35 (see FIG. 13).

  Thus, by providing the shock absorber 15, the rack 35 can be more reliably prevented from suddenly moving in the vertical direction with respect to the rack base 30, and the rack 35 is damaged by the reaction. It can prevent more reliably.

Fourth Embodiment Next, a fourth embodiment of the present invention will be described with reference to FIGS. In the fourth embodiment shown in FIGS. 11 to 13, an eccentric cam roller (position adjusting mechanism) 1 for adjusting the vertical position of the rack 35 and the rack base 30 with respect to the frame 55 is provided on the side of the frame 55. It has been. A dial gauge (position detection device) 25 for detecting the vertical position of the rack base 30 with respect to the frame 55 is provided on the side of the frame 55. Further, the rack 35 is movable in the horizontal direction, and side fixing portions 17 fixed to the frame 55 are provided on both sides thereof. A spring (elastic member) 12 that urges the rack 35 in the horizontal direction with respect to the rack base 30 is provided in the side fixing portion 17. Further, on both sides of the rack 35, a vertical laser displacement meter (position detection mechanism) 21 for detecting the vertical position of the rack 35 with respect to the frame 55 is provided, and the horizontal position of the rack 35 with respect to the frame 55 is detected. A horizontal laser displacement meter (position detection mechanism) 22 is provided. Other configurations are substantially the same as those of the third embodiment shown in FIG.

  In the fourth embodiment shown in FIG. 11 to FIG. 13, the same parts as those of the third embodiment shown in FIG.

  As shown in FIGS. 11 and 12, an eccentric cam roller (position adjusting mechanism) 1 that adjusts the vertical position of the rack 35 and the rack base 30 with respect to the frame 55 is provided on the side of the frame 55. By rotating the eccentric cam roller 1, the eccentric cam roller 1 can be brought into contact with the lower end of the rack base 30, and the rack base 30 and the rack 35 can be pushed upward from below. For this reason, the vertical position of the rack base 30 and the rack 35 with respect to the frame 55 can be adjusted appropriately.

  Therefore, the gap (backlash) between the rack 35 and the pinion 45 can be set to an appropriate value, and the collision of the pinion 45 with the rack 35 in the vertical direction can be minimized. As a result, it can be minimized that the pinion 45 vibrates in the vertical direction and the blanket unit 40 vibrates in the vertical direction with respect to the glass substrate 62. For this reason, the organic layer which consists of a uniform film thickness on the glass substrate 62 can be produced | generated more reliably.

  Further, the vertical position of the frame 55 of the rack base 30 can be detected by the dial gauge 25 shown in FIGS. 11 and 12, and the position of the rack 35 relative to the frame 55 can be detected.

  As shown in FIG. 13, side fixing portions 17 fixed to the frame 55 are provided on both sides of the rack 35 in the horizontal direction, and the rack 35 is placed in the side fixing portion 17 in the rack base 30. A spring (elastic member) 12 is provided for biasing in the horizontal direction. The spring 12 is attached by being pressed against the rack 35 by a spring load adjusting bolt (elastic force adjusting member) 12a penetrating the side fixing portion 17, and adjusts the tightening degree of the spring load adjusting bolt 12a. Thus, the elastic force acting on the rack 35 from the spring 12 can be adjusted.

  Thus, since the side fixing portions 17 fixed to the frame 55 are provided on both sides of the rack 35 in the horizontal direction, for example, the pinion 45 collides with the rack 35 and the force of the horizontal component is applied to the rack 35. Even if it works, the rack 35 can be elastically moved in the horizontal direction with respect to the frame 55, and the pinion 45 can be prevented from vibrating in the horizontal direction due to the impact of the collision. As a result, it is possible to prevent the blanket unit 40 from vibrating with respect to the glass substrate 62, and it is possible to generate an organic layer having a uniform film thickness without forming step unevenness.

  Furthermore, the vertical laser displacement meter 21 and the horizontal laser displacement meter 22 provided on both sides of the rack 35 can irradiate the detection unit 35a attached to the side of the rack 35 with laser light. In response to the reflection of the laser beam from the detection unit 35a, the distances between the vertical laser displacement meter 21 and the horizontal laser displacement meter 22 and the detection unit 35a can be measured.

  For this reason, even if the vertical or horizontal position of the rack 35 is moved with respect to the frame 55 during repeated use of the printing press, it can be immediately detected. Therefore, the position of the rack 35 with respect to the pinion 45 can be maintained at an appropriate position, and the gap between the rack 35 and the pinion 45 can be maintained at an appropriate value. As a result, an organic layer having a uniform film thickness can be more reliably generated on the glass substrate 62.
