  As shown in FIGS. 1 and 5, on both sides of the rack 35, a vertical laser displacement meter (position detection mechanism) 21 that detects the vertical position of the rack 35 with respect to the frame 55 is provided. A horizontal laser displacement meter (position detection mechanism) 22 for detecting the horizontal position of the frame 55 is provided. The vertical laser displacement meter 21 and the horizontal laser displacement meter 22 irradiate the laser beam to the detection unit 35a attached to the side of the rack 35, and receive the reflection of the laser beam from the detection unit 35a. The distance between the vertical laser displacement meter 21 and the horizontal laser displacement meter 22 and the detector 35a is measured.

  The vertical laser displacement meter 21 and the horizontal laser displacement meter 22 can detect the position of the rack 35 with respect to the frame 55 with higher accuracy than the dial gauge 25 described above.

  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 vertical position of the rack 35 with respect to the frame 55 is adjusted (adjustment process). Specifically, after the position of the rack base 30 with respect to the frame 55 is measured by the dial gauge 25 and the eccentric cam roller 1 is rotated by an appropriate amount, the vertical position of the rack 35 with respect to the frame 55 is adjusted. At this position, the rack base 30 is fixed to the frame 55 (see arrow A in FIG. 6A).

  Next, the blanket unit 40 is positioned below, and the pinion 45 and the rack 35 are engaged (engagement step) (see arrow B in FIG. 6A). At this time, since the vertical position of the rack 35 with respect to the frame 55 is adjusted by the adjustment process described above, the gap (backlash) between the rack 35 and the pinion 45 can be set to an appropriate value.

  Next, when the blanket cylinder 41 is rotated (see arrow C in FIG. 6A), the pinion 45 is rotated on the rack 35 and the blanket unit 40 is moved in the horizontal direction with respect to the frame 55 (FIG. 1). Rightward) (horizontal direction moving step) (see arrow D 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 ink received by the blanket 42 is transferred to the glass substrate 62 placed on the work surface plate 57.

  Here, as shown in FIG. 3, a plurality of springs 11 that bias the movement of the rack 35 relative to the rack base 30 are provided between the rack 35 and the rack base 30. 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 film thickness can be generated without forming irregularities (see FIG. 8) that appear as fine streaks perpendicular or oblique to the direction.

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

  Further, as shown in FIG. 4, a shock absorber 15 is provided at the lower end of the rack base 30. The protrusion 15 a penetrates the rack base 30 and is attached to the rack 35. For this reason, even if the pinion 45 collides with the rack 35 in the vertical direction and the rack 35 moves downward, it is possible to prevent the rack 35 from being pushed back up rapidly with respect to the rack base 30 and to push back. It is possible to prevent the rack 35 from being damaged due to an impact at the time.

  Further, as shown in FIG. 5, a spring 12 is provided between the rack 35 and the side fixing portion 17 fixed to the frame 55 to bias the movement of the rack 35 relative to the side fixing portion 17. . For this reason, even if the pinion 45 collides with the rack 35 and the force of the horizontal component acts on the rack 35, the rack 35 can be elastically moved in the horizontal direction with respect to the frame 55, and the impact of the collision Thus, the pinion 45 can be prevented from vibrating in the horizontal direction. 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.

  Further, as shown in FIG. 3, the spring 11 disposed below the rack 35 is pressed against the rack 35 by a spring load adjustment bolt 11a, and the tightening degree of the spring load adjustment bolt 11a is adjusted. By doing so, the elastic force acting on the rack 35 from the spring 11 can be adjusted. Further, as shown in FIG. 5, the spring 12 arranged on the side of the rack 35 is pressed against the rack 35 by a spring load adjusting bolt 12a and attached, and the degree of tightening of the spring load adjusting bolt 12a is adjusted. By adjusting, the elastic force acting on the rack 35 from the spring 12 can be adjusted. From these things, the elastic force which acts with respect to the rack 35 from the springs 11 and 12 can be finely adjusted, and the organic layer which consists of a uniform film thickness can be produced | generated more reliably.

  According to the present embodiment, as described above, the gap (backlash) between the rack 35 and the pinion 45 has an appropriate value, so that the pinion 45 collides with the rack 35 in the vertical direction. Can be minimized. For this reason, 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. As a result, an organic layer having a uniform film thickness can be more reliably generated.

  By the way, according to the present embodiment, even if it is necessary to strongly press the blanket cylinder 41 against the printing plate 61 or the work 62 from the kind of ink or the work (glass substrate or the like) 62, By positioning the rack 35 relatively downward, a gap (backlash) between the pinion 45 and the rack 35 can be increased. For this reason, even if the blanket cylinder 41 slips, the pinion 45 can be prevented from colliding with the rack 35.

  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 E in FIG. 6C). 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 F in FIG. 6C).

  In such a series of steps, the position of the rack 35 relative to the frame 55 is detected by the horizontal laser displacement meter 22 and the vertical laser displacement meter 21. 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. For this reason, the position of the rack 35 relative 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.

  In order to adjust the vertical position of the rack 35 with respect to the frame 55, the vertical position of the rack 35 with respect to the frame 55 is adjusted by rotating the eccentric cam roller 1 by an appropriate amount as described above. After that, the rack base 30 may be fixed to the frame 55 at the position.

  In the above description, the shock absorber 15 for suppressing the rapid movement of the rack 35 with respect to the rack base 30 is described below using the shock absorber 15. In addition, a shock absorber for suppressing the rapid movement of the rack 35 relative to the rack base 30 may be provided on the side of the rack 35. Thus, by providing a shock absorber also on the side of the rack 35, it is possible to prevent the rack 35 from being rapidly pushed back in the horizontal direction by the elastic force of the spring 12 provided on the side. It is possible to prevent the rack 35 from being damaged by an impact when pushed back.

  Further, in the above description, the side fixing portions 17 fixed to the frame 55 are provided on both sides of the rack 35 in the horizontal direction, and the springs (elastic members) 12 are provided in the side fixing portions 17. Although it demonstrated using the aspect, it is not restricted to this, The side fixing | fixed part 17 fixed to the flame | frame 55 is provided only in one side of the horizontal direction of the rack 35, and the spring 12 is provided in the said side fixing | fixed part 17. It may be provided. When the pinion 45 collides with the rack 35, the rack 35 tends to move to one side in the traveling direction of the blanket unit 40. Thus, the side fixing portion 17 and the spring 12 are attached only to one side in this way. When provided, it is preferable that the side fixing portion 17 and the spring 12 are provided on one side of the racket 35 in the traveling direction of the blanket unit 40.

  In the above description, the vertical laser displacement meter 21 for detecting the vertical position of the rack 35 relative to the frame 55 is provided on both sides of the rack 35, and the horizontal direction for detecting the horizontal position of the rack 35 relative to the frame 55 is provided. Although it demonstrated using the aspect in which the laser displacement meter 22 was provided, it is not restricted to this. For example, the vertical laser displacement meter 21 and the horizontal laser displacement meter 22 may be provided only on one side of the rack 35. Further, only one of the vertical laser displacement meter 21 or the horizontal laser displacement meter 22 may be provided on both sides of the rack 35.

  As a matter of course, as in the above-described embodiment, the vertical laser displacement meter 21 for detecting the vertical position of the rack 35 relative to the frame 55 is provided on both sides of the rack 35, and the rack 35 relative to the frame 55 is provided. In the case of using the aspect in which the horizontal laser displacement meter 22 for detecting the horizontal position is used, the position of the rack 35 relative to the frame 55 can be detected with higher accuracy.

  By the way, in the above, it demonstrates using the aspect in which the eccentric cam roller (position adjustment mechanism) 1, the up-down direction laser displacement meter (position detection mechanism) 21, and the horizontal direction laser displacement meter (position detection mechanism) 22 are provided. However, the present invention is not limited to this, and may be an aspect in which these members are not provided.
