Description

[0001] Apparatus for automatically supplying printing plate [0002]

The present invention relates to an apparatus for automatically supplying a printing plate to a printing plate making machine such as a CTP apparatus or the like.

CTP (Computer To Plate) is a branch of image setter technology that simplifies the process between plate making and printing by directly lighting images stored in a computer on a printing plate. It is also referred to as a plate setter because it does not go through the film output process and refers to a process of skipping the step of film output. Since the light source is a laser, super precise image formation is possible. There are violet plate, thermal plate, and computer to coventional plate (CTcP) type according to the type of plate. In tabletop printing (DTP), it is common to generally only print until the print film is pulled out, but in CTP it is possible to omit this film work and draw the printing plate directly. In offset printing, plates of the original size of the publication are made and exposed to an aluminum plate coated with a photosensitive agent to form the printing plate of the printing press. However, since the exposure process using the film is omitted in the CTP, it is possible to reflect the more accurate digital data, so that there is an advantage that the facility or the storage place is not necessary.

The pinion 310 may be directly or indirectly connected to the transmission gears 280 and 282. [ When the fourth motor 290 rotates, the rotational force is transmitted to the pinion 310 through the transmission gears 280 and 282 so that the pinion 310 rotates and is engaged with the pinion 310 by the rotation of the pinion 310 The second lift member 260 connected to the rack 300 can move up and down in the height direction.

8 shows an example of a usable printing plate size corresponding to the printing plate size recognition sensor 18. Six sensor mounting holes 16 are arranged in a line along the width direction of the main body 10, Fourth, sixth, and sixth holes 16, 16, 16, 17, 18, 19, and 20, respectively. Each of the holes 16 may be positioned to correspond to the widthwise size of the printing plate and may correspond to a larger printing plate as it goes down from top to bottom as illustrated in the figure, A larger printing plate can be detected. 8, the printing plate size recognition sensor 18 can detect the printing plate from the end of the printing plate after passing the end of the sensor 18, for example, about 3 mm or later. Each of the printing plate size recognition sensors 18 and each adsorption member is directly or indirectly connected to the solenoid valve 270.

Each hole 16 may be divided into a plurality of zones. For example, as illustrated in the figure, a first zone (zone 1) before the first hole, a first zone (zone 1) The third and fourth holes may be divided into a third zone (zone 3), and the fifth and sixth holes may be divided into a fourth zone (zone 4). Similarly, the plurality of adsorption members 320 may be divided into four regions so as to correspond to the regions of the holes 16. When the printing plate size corresponds to the first area, about three adsorption members 320 can be driven, and the number of the adsorption members 320 operating toward the fourth region can be increased. That is, as the size of the printing plate increases, the force required to adsorb the printing plate increases, so that the number of the adsorbing members 320 to be operated increases. Conversely, if the size of the printing plate is small, it is not necessary to drive the entire adsorption member 320, and only a small number of the adsorption members 320 need be driven.

The operation of the automatic printing plate supplying apparatus according to the present invention is as follows.

The position of the first guide 20 and the second guide 40 is adjusted according to the size of the printing plate and then the printing plate is brought into close contact with the first guide 20 and the second guide 40, Load on top. Since the first guide 20 is provided with the two-piece preventing pad 30, the upper side of the printing plate is substantially in contact with the two-piece preventing pad 30. [

Next, the fourth motor 290 is driven to rotate the transmission gears 280 and 282, and the second lift member 260 is lowered by switching to linear motion through the rack 300 and the pinion 310 When the adsorption member 320 is brought into contact with the printing plate, the vacuum pump is operated to suck the printing plate by vacuum suction. At this time, the operation of the adsorption member 320 is automatically controlled according to the size of the printing plate through the printing plate size recognition sensor 18 and the solenoid valve 270. Since the upper frame 160 is connected to the upper end of the main body 10, only the upper end portion of the printing plate is also adsorbed. At this time, the adsorption member 320 may be rotated in advance through the rotation member 220 so that the adsorption member 320 and the printing plate are perpendicular to each other.

Next, the second lift member 260 is rotated through the fourth motor 290, the transmission gears 280 and 282, the rack 300, and the pinion 310 while the printing plate is in close contact with the two- By lifting the second lifting member 260 as it is or by shaking it up and down a few times, it is possible to separate the printing plate and raise the printing plate up by two or more sheets So that only one printing plate is sucked.

Next, after only one printing plate is adsorbed, the second motor 210 is driven to rotate the second pulleys 200, 202, 204, 206 and the second belts 190, 192, 170 in the height direction of the upper frame 160 to start rising of the printing plate.

Next, when the printing plate rises to a predetermined height beyond the height of the first guide 20, the third motor 250 is driven to rotate the third pulleys 240 and 242 and the third belt 230, (220) is rotated to rotate the printing plate. The reason for rotating the printing plate is that the printing plate is adsorbed at right angles to the adsorption member 320. In order to efficiently and smoothly supply the printing plate while preventing the printing plate from being damaged by contact with other members, the main frame 10 and the upper frame 160 are connected at an obtuse angle, It is preferable to raise it in parallel. Since the printing plate is perpendicular to the suction member 320 on the upper surface of the main body 10 and the main body 10 has an obtuse angle with the upper frame 160, in order to raise the printing plate in parallel with the upper frame 160, To the rear. Specifically, when the printing plate is parallel to the upper frame 160, the printing plate must be rotated backward so that the suction member 320 is perpendicular to the upper frame 160. The second lift member 260 and the suction member 320 are rotated together so that the rotation member 220, the second lift member 260 and the printing plate are separated from the upper frame 160, And the adsorbing member 320 is perpendicular to the upper frame 160. When the printing plate is attracted, the second rotation angle of the rotation member 220 is 90 degrees minus the first rotation angle, because the rotation member 220 rotates back within a range of 10 to 80 degrees in advance. That is, the sum of the rotation angles of the rotary member 220 twice is about 90 degrees.

Next, the printing plate is rotated in parallel with the upper frame 160, and then the first elevating member 170 is continuously elevated in the height direction of the upper frame 160 to continuously raise the printing plate. The rise of the printing plate may be stopped temporarily for the rotation of the printing plate, but the rotation and elevation of the printing plate may be simultaneously performed. When the printing plate is lifted and rotated, a part of the printing plate can be curved.

Next, at the same time as the printing plate is lifted, the scratch preventing arm 50 is rotated to the upper end portion of the main body 10 (at the home position (position)) by rotating the first motor 90, the first pulleys 80, ) To the lower end. The driving of the scratch prevention arm 50 can be started at the time of rotation of the printing plate. The scratch preventing arm 50 moves while supporting the middle portion and the lower portion of the printing plate still remaining on the side of the main body 10 in order to prevent or minimize the damage of the printing plate to be moved next.

Next, when the printing plate rises to the upper end of the upper frame 160 or to a desired height, the operation of the vacuum pump is stopped to detach the printing plate from the suction member 320, thereby supplying the printing plate to the CTP apparatus by free fall. At this time, the printing plate may be further rotated and dropped through the rotating member 220 to adjust the final supply position and supply angle of the printing plate. After supplying the printing plate, the first elevating member 170 is lowered and the scratch preventing arm 50 is returned to the home position for supplying the next printing plate.

The operation procedure of the above-described automatic printing plate supplying apparatus is an exemplary one, and the operation order and the method may be appropriately changed as necessary.

In the present invention, when the printing plate size recognition sensor 18 recognizes the size of the printing plate, the solenoid valve 270 operates according to the size of the printing plate, Can be automatically controlled.

Second, in the present invention, it is possible to effectively prevent two or more printing plates from being fed at a time by providing the two-piece prevention pad 30. [

Thirdly, in the present invention, damage to the printing plate can be effectively prevented by the scratch-preventing arm 50 or the like.

Fourth, in the present invention, the adsorption member 320 and the printing plate are configured to be rotatable, whereby the printing plate can be prevented from being damaged and the printing plate can be efficiently and smoothly supplied. Conventionally, there is no rotation function of the adsorption means or the printing plate.

Fifth, in the present invention, the configuration of the scratch prevention arm 50 is relatively simple and the driving method is efficient. Conventionally, a plurality of wires (about six wires) are installed and driven in the form of a brush, which is complicated and inefficient.

Sixth, in the present invention, the docking rail 140 is installed to easily connect the autoloader and the CTP apparatus.
