Effects of the Example Next, the screen printing machine configured as described above (
The action of Pullpurin I Base 16 will be explained.

Now, when performing multi-color printing with the screen printing machine of this embodiment, it is necessary to align the printing material of the print base 16 J: with the screen plate 9 at the right Tll1. (Ma Z handle 20
．． The X die A2 19 and the Y die IX/21 are rotated as appropriate to adjust the vertical, horizontal, and longitudinal positions of the printing material.

First, when adjusting the vertical direction of the printed material (l□l11), as shown in FIGS. 2 and 3, rotating the Z handle 20 moves the drive shaft 33 and the Each vertical shaft 27 is rotated to the left or right via the second and third driven shafts 35, 36, 37, and the vertical shaft 27 and the leg cylinder 24 integrally move inside each support 111126 of the machine base 1. It is moved up or down. Prior to this, when the J company selection switch on the operation panel (not shown) is switched to the up/down (?) movement amount display position, the amount of movement in the up/down direction of the lifting body 17 is the third The rotary encoder 4 connected to the driven shaft 37 of
0 is detected and the numerical value is displayed on the display section 22. Therefore, the operator rotates the 7 handle 20 until the numerical value Δ displayed on the display 22 reaches the desired feed amount, and then the upper surface of the pudding 1 head 16 faces the screen plate 9 correctly. It can be placed in any vertical position.

Next, we will explain the case where the front and back position and inclination angle of the printing material are adjusted by operating the full 21 to the left and right Y ties, mainly based on the J-schematic diagram shown in Figures 8 and 9. Then, as shown in Fig. 8, when J5 is in the poly-neutral position and the left side Y-dial A/ru 21 is rotated and the other die A full shaft 71 is projected forward, as shown in Fig. 9 (1), The left side of the planar moving body 18 is moved toward the rear by being pulled by the first tension spring 64 on the left side.Also, in the neutral position, the knob 21 is connected to the Y die on the G side) (If you rotate the dial shaft 71 in the opposite direction to the dial 21 and (31),
The plane moves against the spring force of the first tension spring 64 on the right side.
The right side 111 of the member 18 is pulled out forward, and the planar moving member 18 is tilted in one direction with respect to the elevation member 17.

Then, prior to this, the selection switch is switched to the desired display position (both the left and right Y die), and when the /le 21 is operated, each moving vehicle is detected by each [ ] - tally encoder 94. Then, the respective numerical values are displayed on the display section 22. Therefore, the operator
If these values displayed on the screen match the desired feed ω, then rotate both Y-tie
V; Accurately go to the plate match U of the printing substrate in 2.jJ-9.

Also, at this time, the second tension spring 111 described above
forces the planar moving body 18 by an external force, and the guide plate 1
Since the engaging surface 116 of 13 is locked and held by the engaging protrusion 115 of the middle plate 13, the center of tilt of the movable body 18 can be moved from side to side.
t,,=Zintemae<D L g'fi)+Sarel J
, Tsu M ', r li, therefore one 4! ! In this way, single movement guidance and longitudinal movement guidance of the planar moving member 18 are possible. , Therefore, the middle plate 43 can be moved back and forth.
At the same time, the structure can be made into a cylinder compared to the case where the planar moving member 18 is rotatably supported on the middle plate 43-1.

Moreover, ffi 61'i! 1 and FIG. 7, the locking groove 90 of the die full shaft 7'1 and the stepped sleeve 85
Since the locking ball 91 is interposed between the leaf springs 88 and 88, there is no play between the two, and the rotation of the Y tie cell 21 is controlled to the first. Til [
It can actually cover the transmission. Moreover, tier 1'' sleeve 8
5 spring 105 forces the first gear 96 in the anti-114δ1 direction (see FIG. 7), and this and Ili! The gear with the matching detection tooth width 95 is pressed against the tooth surface of the second gear 97.
C, the backlash between the second gear 97 and the detection gear 95 is reliably eliminated and the rotary engine-1-ri 94
It is possible to prevent errors in the detection of d3.

Therefore, the number 11C1 displayed on the display section 22 is extremely accurate, and the plate alignment of the printing material that overlaps the screen plate 9 is performed reliably. Beautiful multicolor printing can be done.

On the other hand, when adjusting the left and right position of the printing material, the above)
Move the y-board switch to the left/right movement amount display position.
Rotate the Cx Daiguille 19. Then, as shown in Fig. h42, the C driven gear 125 is moved to the center via the The amount is 1]-(a is output by the tally encoder 128 and displayed on the display section 22.

Therefore, as shown in FIG. 10, by operating both the left and right Y-die A full 21, the plane moving member 18 is rotated (in the solid line position in the moved state), and the X-tie A/le 19 is rotated. The deviation is caused by the parallel movement to the right (to the chain line position) while the plane moving body 18 remains in an inclined state. After being sent to A1, it is moved to A2 to the right without changing the front-rear position. Therefore, as shown in Fig. 11, in contrast to the conventional case, the front and rear positions are changed according to the a-i j position key ■ ij, and the screen version disappears. 9 and the position of the printing material (Kli)i) can be easily and accurately performed.
8 in parallel back and forth, it is sufficient to move both the left and right Y-die A full 21 by the same amount, and further,
In this state, if the X-driver 19 is operated, the planar moving body 18 will be moved horizontally in parallel with the same front and back device. J3, the (hyperactive fft) position of the planar moving member 18 shown in chain lines in FIGS. The two chain line positions IJK indicate the actual maximum inclination positions.In addition, the intermediate plate 43 at a5 in FIG.
