A TFT LCD monitor 29 is provided which simultaneously outputs images input from the camera 28 of the camera. Two cameras 28 are installed on the left and right sides of the upper cover 27, and each camera 28 is attached to a camera bracket 31 sliding horizontally along the camera guide plate 30. The bracket 31 is attached with a ball screw nut 34 engaged with the camera lateral feed screw 33 driven by the camera lateral feed motor 32.

The punching cylinder 35 of the punching part 3 is installed in the base plate 9, and the rod of the punching cylinder 35 has a punch arm whose end is hinged to the bracket attached to the main plate 4 by the hinge 36. The other end of the 37 and the connecting arm 38 are hinged by a hinge, and the punch 39 is hinged by a hinge on the hinge 36 side of the punch arm 37.

In the drawings, reference numeral 40 denotes a PS plate, 41 a recess groove, 42 a register mark, 43 a camera longitudinal feed motor, 44 a camera longitudinal feed screw, 45 a guide shaft, and 46 Side plate, 47 is camera low plate, 48 is guide, 49 is panel PC, 50 is vision sensor, 51 is C / V, 52 is MICOM CONTROL BOARD, 53 is stepping Motor, 54 is the server.

According to the present invention, the recess groove 41 is formed at the correct position in order to accurately mount the plate 40 to the plate cylinder of the printing machine. In the case of color printing, the plate 40 is required by the number of chromaticities. All of the PS plate 40 is to be formed in the groove groove 41 is exactly the same position to obtain a good print.

Since the punching position of the concave groove 41 is based on the register mark 42 baked on the PS plate 40, the punching position 41 should be set to accurately detect and register the register mark 42 baked on the PS plate 40. Then, the recessed grooves 41 should be formed in all the PS plates 40 at the same position with respect to the set position of the register mark 42. Therefore, the present invention is configured to enable fine adjustment of the PS plate 40 so that the camera 28 can accurately locate the registered register mark 42, and the tracking of the register mark 42 can be conveniently configured by a computer system. And it is configured to be able to punch the recess groove 41 accurately.

That is, the PS plate 40 with the register mark 42 baked is placed between the slide blocks 8 on both sides of the main plate 4, and the upper pusher of the clamping part 1 is formed at the corner where the recessed groove 41 is to be formed. Push in between the 16 and the lower pusher 14 until it contacts the rack 17 protruding above the main plate 4. The handle 7 is provided in the upper part of the slide block 8, the wire rope 6 is changed in the movement direction by the pulley 5, and the slide block 8 is attached to the wire rope 6 part from which the movement direction differs. Are fixed to each other, and one slide block 8 is moved in one direction with the handle 7 and the other slide block 8 is moved by the same displacement in the opposite direction.

Therefore, if the slide block 8 is moved to the center with the handle plate 7 in between, both slide blocks 8 move with the same displacement to the center, so that the Ps plate 40 is aligned to the center. Can be. Then, when the pusher cylinder 12 is operated to push up the load rack 13, the lower pusher 14 approaches the underside of the PS plate 40, and the pinion 15 engaged with the rod rack 13 by the rising of the load rack 13. Rotates counterclockwise to lower the rack 17 on the left side, so that the upper pusher 16 fixed to the upper part of the rack 17 approaches the upper surface of the PS plate 40 so that the upper pusher 16 and the lower part are lowered. The pusher 14 presses and fixes the PS plate 40.

The camera 28 tracks the position of the register mark 42 in order to set the position of the register mark 42 of the PS plate 40 fixed in the above process as a reference value. By the 32 and the camera horizontal feed screw 33, the longitudinal feed is by the camera vertical feed motor 43 and the camera vertical feed screw 44.

That is, when the camera horizontal feed motor 32 rotates, the camera horizontal feed screw 33 is rotated, and is engaged with the ball screw nut 34 of the camera bracket 31 to which the camera 28 is attached. Will be transported horizontally. In addition, when the camera longitudinal feed motor 43 fixed to the base plate 9 rotates, the camera longitudinal feed screw 44 is rotated, and the ball screw nut 34 engaged with the camera longitudinal feed screw 44 is frame 25. Since it is fixed to the camera low plate 47 fixed to the side plate 46 sliding along the guide shaft 45 at both upper ends, the camera 28 is transferred in the vertical direction.

In this process, since the two cameras 28 are equally displaced in the vertical direction, the registration mark 42 of the PS plate 40 cannot be accurately focused when the vertical position is incorrect. Therefore, in this case, the clamp plate 11 clamping the PS plate 40 should be rotated and adjusted.

Here, on the left and right sides of the clamp plate 11, the lower bracket 18 attached to the base plate 9 has a clamp plate vertical adjustment motor 19, a male screw rod 20 and a transfer nut 21 engaged therewith. The transfer nut 21 is in contact with the upper bracket 22 attached to the lower portion of the clamp plate 11, the upper bracket 22 and the lower bracket 18 is connected to the coil spring 24. Therefore, when the clamp plate vertical adjustment motor 19 rotates, the transfer nut 21 engaged with the male rod 20 slides along the guide 48 to push the upper bracket 22, and when the shaft rotates in the opposite direction, the transfer nut 21 moves. Since the nut 21 is only in contact with the upper bracket 22, the clamp plate 11 is moved by the coil spring 24. Therefore, there is an effect that the clamp plate 11 is rotated by only one operation of the clamp plate vertical adjustment motor 19 provided on both sides of the clamp plate 11. The overall horizontal direction adjustment of the clamp plate 11 is performed by the clamp plate horizontal adjustment motor 23, and the operation is the same as that of the vertical direction adjustment.

In addition, since the clamp plate 11 is mounted on the top of the four ball transfers 10, the movement is free, and the upper bracket 22 attached to the bottom surface is contacted without being fastened to the transfer nut 21, so that the degree of rotation It becomes possible.

In the above process, the camera 28 accurately focuses on the register mark 42 of the PS plate 40, sets the value to a reference value, and then performs punching to form the recessed groove 41 in the PS plate 40. Will be done.

After the setting is completed, the camera 28 is fixed until the recess groove 41 is formed in all the PS plates 40 necessary for printing, and the PS plates 40 are moved to focus on the fixed camera 28. The register mark 42 of the PS plate 40 must be matched. If the register mark 42 of the PS plate 40 coincides with the focus of the camera 28, the recess groove 41 is formed in the PS plate 40. Done.

That is, the punching cylinder 35 is installed in the base plate 9, and the rod of the punching cylinder 35 is formed of the punch arm 37 axially fixed by the hinge 36 at one end of the bracket attached to the main plate 4. The other end and the connecting arm 38 are hinged by a hinge. The punch 39 is axially hinged on the hinge 36 side of the punch arm 37. Therefore, when the rod is retracted by the operation of the punching cylinder 35, the punch arm 37 is rotated about the hinge 36 by the connecting arm 38, and one end of the punch 39 is the punch arm 37. Since it is connected by a hinge to the rotary arm of the punch arm 37 is converted to the vertical movement of the punch 39, the blade portion of the punch 39 punches the PS plate 40 to form the recessed groove (41). .

As described above, the reference setting value is set to the first PS plate 40, the recess groove 41 is formed, the PS plate 40 is removed from the punching machine, and another PS plate 40 is removed from the main plate. 4), the clamp plate 11 is adjusted to set the register mark 42 of the PS plate 40 and punched in accordance with the focus of the fixed camera 28, so all the PS plates 40 are register marks. Concave indentation groove 41 is formed at the same position with respect to (42). The focus of the camera 28 is displayed on the TFT LCD monitor 29 at the same time on both the left and right cameras 28, and the register mark 42 of the PS plate 40 is aligned with the focus center thereof.
