BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for processing a scroll, wherein the scroll (e.g. paper) is provided by a printing, copying or other marking process (hereinafter referred to as printing in general) and a handling device such as a folding device or a type adjusting device. The present invention relates to a processing method and an apparatus capable of performing an operation of forming an image on an image. The present invention relates to, but is not limited to, a treatment apparatus in which paper or other material is released from a continuous roll on a roller.

It is well known to pass a paper from a roller through a printer to form a series of images on the paper and then rewind, cut, or fold the paper into various formats. However, there is a fundamental problem in this prior art that serious limitations are placed on the efficiency of the printing press. This is a problem called "stop time". Once the printer is up and the paper starts running, printing happens very quickly. However, in a known printing press, a long time delay may occur when the feeding method of the roll or the printing target is changed. For example, if a different image is printed, the repeat range of the image is changed, different colors are used, or the folding format is changed, the print job must be stopped. The configuration of a known printing press is extremely difficult to make such a change, so that the non-operating time (stopping time) of the printing press is much longer than the effective operating time.

Another problem with the conventional apparatus is that the printing press is configured to apply only to one particular printing, and such printing press is sold only as a single item. This actually means that if the owner of the press wants to do something more complex than what the machine can do now, the owner has to rebuild most of the work or buy a completely new machine.

Therefore, the gist of the present invention is to overcome the above problems or at least to improve the above by configuring a scroll processing device having the advantage that can be changed during the feeding during the operation and to expand the capacity if necessary.

The scroll processing system according to the present invention is divided into three parts, the first of which is to unwind the roll from a roll or rail and feed it to another part of the apparatus, and the second is to print an image on the scroll, and the third is It is the part of the device that processes the printed scroll. The present invention relates to three parts of the device.

TECHNICAL FIELD The present invention relates to an imaging apparatus, and in particular, but not exclusively, to a paper feed press. Such presses typically have a pair of blanket cylinders (blanket to blanket configuration) through which a roll passes for each color to be printed and for repeated print lengths, a pair of plate cylinders in contact with the blanket cylinder and mounted with the image to be printed, Ink and dampening device for a pan cylinder. These devices are known as "complete" presses because they print on both sides of the roll. It is also already known to have one pressurized cylinder, a single blanket cylinder, a plate cylinder, an ink and a wet water device when printing only one side of the scroll.

The present invention includes a plurality of cartridges comprising a set for printing a roll that can be fed through each set of cartridges, each cartridge having a means for transporting the print medium from the device containing the print medium to the roll. Wherein the means comprises at least one printing cylinder suitable for contacting the scroll with at least one printing cylinder of one cartridge having a different circumference than the other, the cylinders of different sizes each providing different printing lengths, It is printed by at least several cartridges with different size cylinders present simultaneously in the device during printing. The cartridges form a roll fed offset printing press, where each cartridge has a pair of plate cylinders corresponding to a pair of blanket cylinders. Thereafter, a joint device, which is an ink and a damping device movable relative to the cartridge, may be configured to selectively provide at least some of the pan cylinders of the cartridge, or the cartridge itself may be selectively moved. Thus, a finely changeable printing process is possible in which the following characteristics can be performed. This property is characterized in that the ink and the wet water device are arranged in the operating position with respect to the first cartridge, and a print job is made for this cartridge; The blanket cylinder of the first cartridge is then moved away from the roll; Then, the blanket cylinder of the second cartridge (the image in this cartridge is different in size or color from that of the first cartridge) is moved to contact the scroll when the ink and dampener completes moving to the second cartridge. . Thus, a new print job can be started in the second cartridge in a very small time. It is also possible to change the image on the plate cylinder of the first cartridge while the printer is in operation.

The apparatus according to the invention may comprise a plurality of inks and plungers for simultaneously supplying different colors to a plurality of selected cartridges (at least not the same number of cartridges are provided). It is also possible to have a plurality of sets or stacks with dryers or to have cartridge exchangers as necessary.

The printing cylinder may be a blanket cylinder of an offset press, in which a plate cylinder is installed between the blanket cylinder and the device containing the printing medium. For offset full presses, a blanket cylinder and a corresponding plate cylinder are provided on each side of the roll. For the other offset frets, one cylinder of cylinders and a pressure cylinder on the other side of the roll are installed. In addition, the intaglio press is etched in the printing cylinder, and the printing medium is transferred directly from the ink and the dampening device to the printing cylinder. Similarly, in flexograghpic or letter press, the print media is transferred directly to the cylinder, where the cylinder has a block face that supports the print media. In the case of such intaglio press, flexographic and letter press, a pressurized cylinder is installed on the side of the roll toward the printing cylinder.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail. It also describes other features of the printing apparatus. These features are merely to aid the understanding of the present invention and are not intended to be embodiments of the present invention.

In FIG. 1, the scroll processing apparatus of the present invention is shown in three parts. The first portion 1 is a portion which takes out paper from one or more rolls in the form of a roll 2 and feeds it to the printing apparatus 3 and the drying apparatus 4. As shown in FIG. 1, the paper roll 2 is folded at 90 ° and proceeds to the cutting and grounding device 7. The rolls after the image printing are completed are stacked by moving in the direction of the arrow after cutting or folding. Of course, the arrangement of the paper roll feeder 1, the printing station 3, the drying station 4, the cutting and folding device 7 can be provided in any one, and the actual shape is determined by the limitation of space and the like. do.

As described in FIG. 1, the scroll passes through the printing apparatus 3. 2 shows an embodiment of the printing apparatus 3, which is a roll-feed offset complete press according to the present invention. While the illustrated embodiment shows all printing cylinders of the same size, this is only a schematic illustration of the mechanism, and the present invention provides at least one cartridge having a cylinder different from that of another cartridge. The press has three cartridges 40, 41 and 42, each of which has a pair of blanket cylinders 43 and 44 and a pair of plate cylinders 45 and 46, respectively. A printing plate is formed on an outer surface of each of the plate cylinders 45 and 46, and the plate cylinders contact each other with one of the blanket cylinders 43 and 44. Each cartridge eventually contains one print pair. As a rule, it is already known that the plate cylinder and the blanket cylinder have the same diameter, and besides, the circumference of the plate cylinder is 1/2 of the circumference of the corresponding blanket cylinder. As shown, the cartridges 40, 41, 42 are immediately adjacent to each other, which makes the cartridge sets 40, 41, 42 smaller in size. However, the cartridges 40, 41, 42 may also be in spaced sets. The roll 2 passes around the roller 47 and passes between a pair of blanket cylinders 43 and 44 of each cartridge. The cartridges 40, 41, 42 are preferably stacked vertically, but the cartridges 40, 41, 42 may be arranged completely horizontally. In this case, however, all cartridges must be able to move transverse to the scroll. The image to be printed on the roll is conveyed on the plate cylinders 45 and 46 and transferred onto the scroll through the blanket cylinder. This itself is as already known.

As shown in FIG. 2, there are devices on both sides of the roll that include print media, i.e., ink and dampening trains 48,49. The trains 48 and 49 can be moved together or vertically separately, and each can also include a draw-off device to facilitate such vertical movements.

When the printing process begins, the ink and damp water trains 48, 49 move vertically to fit one of the cartridges 40, 41, 42. The ink and damp water roller 50 is moved to a position in contact with the plate cylinders 45 and 46 by a mechanism that ensures correct operation shape and input. As shown, the ink and wet water trains 48, 49 are located on either side of the roll but have a common relationship with the three cartridges 40, 41, 42. If the cartridge 41 is to be printed, the trains 48 and 49 are operated to move the ink and the damp roller 50 in contact with the two plate cylinders 45 and 46 of the cartridge 41. The print job then begins. After the print job is complete, the ink and wet water trains 48 and 49 move in a draw-off form (as shown for 48) and move vertically until they are close to one of the other two cartridges 40 and 42. Move. A new printing process is performed by the ink and the damp roller 50 contacting the plate rollers 45 and 46 of one of the two cartridges 40 and 42.

It is also possible to move the cartridge vertically with the train fixed. However, this is a very difficult problem mechanically. However, such a device allows to be embedded inside the cartridge machine, which is more effective than conventional devices.

3 and 4 illustrate a suitable drive for driving the press of FIG. As shown in the plan view of FIG. 3, the ink and damp water trains 48 and 49 are movable relative to the main frame 52 of the press supporting the cylinders 43, 44, 45 and 46 via the end support 52a. It is mounted on the support frame 51. Although the horizontal movement mechanism of the ink and damp water trains 48 and 49 is illustrated, in FIG. 2, the stopper 53 is provided on the support frame 51 to limit the horizontal movement. Doing.

The vertical movement of the support frame 51, that is, the vertical movement of the ink and damp water trains 48 and 49, is controlled by a winch motor 54 mounted on the support frame 51. The motor 54 extends across the support frame 51 and drives the shaft 55, which is connected to the two shafts 58, 59 via the bevel gears 56, 57. The axis 58 drives the pinion 60 which is engaged with the gear rack 61 on the main frame 52, and likewise the axis 59 is the corresponding gear rack 64, 65 on the opposite side of the main frame 52. ) And two pinions 62 and 63, which are also attached to the main frame 52, respectively. The rotation of the motor 54 thus drives the shafts 55, 58, 59 and thus the pinions 60, 62, 63 move down or up on the corresponding racks 61, 64, 65, respectively. Accordingly, the support frame 51 moves with respect to the main frame 52. In this installation, three-point mounting was used but it is also possible to apply four-point or more multipoint mounting. However, at this time, the pinion on the shaft 58, 59 should be provided to the rack on the main frame 52. Accurate vertical positioning of the support frame can be achieved by precise control of the motor 54 or by providing a stop 66 as shown in FIG. 2 on the main frame 52. The stop 66 is spring loaded so that the support frame 51 moves away from the main frame 52 as it passes through the stop 66 so that the support frame 51 stops 66. Descends up. Clearly the stopper 66 must be depressurized to allow lower movement of the support frame 51, ie to operate the cartridge 40 in FIG. 2.

Next, the driving operation of the cylinders 43, 44, 45, 46 will be described. In practice, the drive trains for the cylinders 43 and 45 and the drive trains for the cylinders 44 and 46 are identical to each other and therefore the description is limited only to the drive trains for the cylinders 43 and 45.

The axis 67 extends upwardly in the main frame 52 and can move over the frame 52. However, a gear 68 is provided for rotation with the biaxial 67, which gear 68 is connected with a shaft 70 extending toward the worm 71 which is fitted to the worm wheel 72. ) Is engaged. The shaft 73 is fixed to the worm wheel 72 and supported on the support frame 51 by the support 74. An air cylinder 75 is installed at the end of the shaft 73 away from the cylinders 43 and 45, which moves the shaft 73 in the axial direction. The other end of the shaft 73 is provided with a clutch plate 76 that engages with a corresponding clutch plate 77 on the stub shaft 78 extending from the plate cylinder 45. Clutch plates 76 and 77 and their shafts 73 and 78 penetrate through openings 79 in main frame 52. The end of the plate cylinder 45 is provided with another gear 80 engaged with the mating gear 81 of the blanket cylinder 43.

Therefore, when the air cylinder 75 drives the shaft 73 and the clutch plates 76 and 77 mesh with each other, the driving force from the shaft 67 is gears 68 and 69, the shaft 70, the worm 71, The worm gear 72, the shaft 73, the clutch plates 76 and 77, and the stub shaft 78 are sequentially transmitted to the plate cylinder, and are thus finally delivered to the blanket cylinder through the gears 80 and 81.

When the air cylinder 75 drives the shaft 73 to isolate the clutch plates 76 and 77 from each other, the driving force is not transmitted. Moreover, such movement of the shaft 73 is sufficient to move the clutch plate 76 slightly spaced from the opening 79 so that all assemblies on the support frame move to another cartridge relative to the main frame 52. It is possible. This installation does not transmit any driving force to the cylinder of the cartridge that is not in use and also provides the advantage of safe operation when replacing the printing plate of such cylinder. Since it moves with the ink and damp water trains 48 and 49 of the cylinder drive mechanism, it is unlikely that accidental driving of a cylinder that does not print at any particular time will occur at all.

The clutch formed by the clutch plates 76, 77 has another function. The clutch plates 76 and 77 will pre-adjust the clutch to a single position to match the position of the corresponding plate cylinder 45 to the driving state. Therefore, the rotation of the plate cylinder 45 coincides with the rotation of the shaft 67 regardless of the initial position of the plate cylinder 45.

However, in some cases it is necessary to change the timing coincidence of the shaft 67 and the plate cylinder 45, which is when it is necessary to advance or retract the print image with respect to the main driving force. In order to achieve this demand, the worm 71 is moved along the axis 70 by a linear actuator 82, which linear bearing 82 typically bears a worm 71 fixed on the axis 70. . This rotates the worm wheel 72 and thus rotates the plate cylinder 45 relative to the position of the drive shaft 67 via the shaft 73 and the clutch plates 76, 77. In addition, the movement of the worm 71 may be performed using a motor or a hydraulic ram. The movement of the pan cylinder 46 with respect to the shaft 67 is carried out in the same manner as in the pan cylinder 45, which can be selected simultaneously with the movement of the pan cylinder 45 or separately.

The driving of the ink and damp water trains 48 and 49 to the ink and damp water cylinder 50 will be described with reference to FIG. 4 is the same drawing as in FIG. 2 but omits the cartridges 40, 41 and 42 for clarity. Here, the driving method from the hoisting motor 54 is used to move the support frame 51 with respect to the main frame 52.

As shown in FIG. 4, the gear 83 extends toward the worm 71 in the shaft 70 and the gear 69. Gear 83 is connected to epicyclic gear 84 on shaft 85. Each end of the shaft 85 supports a gear 86 that meshes with a gear 87 that is connected to a drive system in the ink and moistening device as in the conventional manner. Thus, the shaft 70 is connected to the driving force from the shaft 85 and the shaft 89, which drive each cylinder 43, 44, 45, 46 as shown in FIG. Drive 50.

However, this timing coincidence depends on the diameter of the pan cylinders 45 and 46. If the press has cylinders with two different sizes as in the present invention, the drive as described above can only be matched for one size. Thus, the print job is out of alignment when the ink and wet water trains 48 and 49 are moved to cartridges having cylinders of different sizes. The apparatus shown in FIG. 4 overcomes this problem by providing an auxiliary drive motor 88 connected to the shaft 85 via an epicyclic gear 84. The rotational speed of the auxiliary motor 88 is sensed and the information is sent to the comparator 89, where the rotational speed of the roller 90 through which paper passes and the rotational speed of the drive motor 88 are compared. The roller 90 may also carry an epicyclic gear. If the driving state is found to be inconsistent, the speed of the motor 88 is increased or decreased until it is matched. Therefore, the driving force of the motor 88 is to change the driving force transmitted to the shaft 85 by the gear 83.

4 shows another feature of the device according to the invention, in which an axis 67 for driving the plate cylinder and the blanket cylinder is driven from an axis 91 extending beyond the printing station. Thus, an additional print station may be connected to the shaft, or connected to the perforator of the former grounder 92, as shown in FIG. 4, or to the perforator and cutter of the cutting station. This will be explained in more detail later. However, as shown, the main shaft 91 has a gear 93 for driving the shaft 94 of the pre-grounder 92 for rotating the perforator 95. In addition an epicyclic gear 96 is provided and connected to the comparator 89.

As shown in FIG. 2, a pair of ink and wet water trains 48 and 49 are provided for common application to three cartridges. Therefore, the three cartridges may have different images on each plate cylinder, and may include at least one cartridge having a different cylinder size, so that the printing length may be varied by changing from one cartridge to another cartridge. Can change. However, other installations are possible, for example in FIG. 5 an embodiment having four cartridges 100, 101, 102, 103 identical to the three cartridges 40, 41, 42 shown in FIG. 2. In this embodiment the scroll 2 moves up through the center of the cartridges 100, 101, 102, 103. Four ink and damp water trains are provided and a pair of trains 104 and 105 at the top act on the two cartridges 100 and 101 at the top and a train 106 and 107 at the bottom act on the two cartridges 102 and 103 at the bottom. In this way, it is possible to print two different colors in a printing cylinder of the same size, and it is possible to maintain the exchange or repetition length of the image. Also, as shown in FIG. 5, the cylinders of each cartridge have different sizes, for example, making the cylinders of the cartridges 100, 102 smaller than the cylinders of the other cartridges 101, 103. The press shown in FIG. 5 is in a position spaced apart from the four cartridges as described above, and is substantially the same as the press of FIG. 2 but has a drive as shown in FIG. 3 and FIG. Therefore, detailed description of the apparatus of FIG. 5 is omitted.

One characteristic of this device is that it is possible to increase the number of different printing jobs by adding cartridges and thus adding ink and water trains 48 and 49.

The embodiment described in FIGS. 2 to 5 has an ink and a damper device that moves vertically with respect to the vertically stacked cartridge set. However, a horizontal device is also possible in which the cartridges are installed in a fixed horizontal set and the ink and wet water device can move relative to the cartridge at which printing starts. One or two ink and moistening devices may be used. The driving of the ink and dampening device and the plate cylinder is as described in the vertical device shown in FIG. The difference is that a horizontal power shaft operating in parallel with the main power shaft can be used to drive the plate cylinder. Driving from the main power shaft is by means of a vertical axis connecting the main power shaft to the horizontal axis via two pairs of bevel gears.

As mentioned above, the cartridge set is fixed and the ink and wet water device can be moved. Since the present invention is subject to relative movement, it is also possible to conversely fix the ink and wet water device and allow the cartridge to be moved. The cartridge can be moved in many ways, for example by a roller guide rail or a pneumatic jack. And the drive to the plate cylinder can be performed by one gear clutch as shown in FIG. An advantage of a device using a movable cartridge is that the drive to the device is fixed because the ink and water dispenser is fixed. However, it is a common belief that the cartridge is much more difficult to make movable than the ink and moistening device is movable.

6 and 7 show a device for fixing the ink and the wet water device and movably constituting the cartridge, but which are not included in the present invention but for informational purposes only. The device has four cartridges 111, 112, 113, and 114 to form one carousel 115. As shown in FIG. 6, each cartridge has a pair of plate cylinders 116 and a pair of blanket cylinders 117, the format of which is the same as the embodiment of FIG. As can be seen in FIG. 6, the plate cylinders and blanket cylinders 116, 117 of the cartridges 111, 113 are smaller than the cylinders 116, 117 of the cartridges 112, 114. Because of this, the cartridges 111 and 113 and the cartridges 112 and 114 can provide different repeat lengths.

The roll 2 enters the printing machine through the rollers 118 and 119 and moves along the horizontal path through two cartridges 112 and 114 of the four cartridges 111, 112, 113 and 114 of the carousel 115. The carousel 115 is rotatably supported on the frame 120, and the other frame 121 supports one or two ink and wet water devices 122 (one in FIG. 7). One ink and the wet water device 122 is preferably installed on the side of the carousel is fed scroll. The two ink and the wet water device are usually installed at both sides of the carousel to drive the cartridges 111 and 113 or the cartridges 112 and 114.

The printing press shown in Figs. 6 and 7 operates in one of several ways. For example, it is possible to perform one print job using only one cartridge 114 and to perform another print job with another cartridge 112 during this print job. When the printing operation on the cartridge 114 is completed, the blanket cylinder 117 of the cartridge 114 retreats from the roll 2, the driving force to the cartridge 114 is removed, and the blanket cylinder of the cartridge 112 ( 117 moves to the position where it contacts the scroll 2 and a driving force is transmitted to this cartridge 112. After the printing operation is performed using the cartridge 112 in this manner, the next cartridge 114 is prepared. If the cartridges 112 and 114 have the same print repetition length and print diameter, the two cartridges 112 and 114 may be used to perform two color jobs in a serial format.

In order to change the print job to the cartridges 111 and 113, the motor 123 drives the carousel 115 to move the carousel 115 on the frame 120 by 90 °. In this way, the cartridges 111 and 113 are aligned with the scroll 2. The exact positioning of the carousel 115 may be performed by bearings (not shown) and the rotation of the carousel 115 must be torn in order for the scroll 2 to change from one pair of cartridges to another. This device is of less advantage than the embodiment of the invention shown in FIG. As indicated by the arrow 124, the carousel 115 may be rotated clockwise or counterclockwise as necessary.

The driving apparatus for the apparatus of FIGS. 6 and 7 will be described. In particular according to FIG. 7 the shaft 125, which can be connected to the drive for the entire printing apparatus as described in FIG. 4, is connected via the gear 126, the shaft 127, and thus through the gear 128. And a driving device 129 for the wet water device 122. The driving device 129 is similar to that described in FIG. 4, and the driving force may be transmitted through the epicyclic gear 130 operated by the auxiliary motor 131 to match the timing of driving.

The shaft 127 also has a gear 132 connected to the worm 133 operating on the worm wheel 134. The worm wheel 134 rotates the shaft 135, and is provided with a preceding actuator 136 at one end of the biaxial 135 and a clutch 137 at the other end. The clutch 137 is connected to the shaft 138 which drives the plate cylinder 116 of one of the cartridges 111, 112, 113, and 114. Thus, the drive of the cartridge in this device is similar to that in FIG. 3, and therefore its operation is immediately apparent.

As outlined on the right side of FIG. 6, the shaft 127 may extend to both edges of the carousel 115 to drive other inks and moisturizers (not shown).

Another improvement of the apparatus shown in FIG. 2 (figure 5, 6 or 7) relates to the mounting of the cylinder in the cartridge 40, 41, 42 or 100, 101, 102, 103 or 111, 112, 113, 114. If the cylinder is mounted in the conventional manner, it is evident that a problem arises in that the printing position must be correctly set and the length selected again whenever the cartridge needs to be changed. Thus, in the device of the embodiment of the present invention, there is provided a device for easily discharging and mounting the blanket cylinder at the correct contact position. If the blanket cylinder is in contact, printing is performed. It is also possible to prevent the blanket cylinder from being released in contact without interrupting continuous printing, for example by different cartridges. Furthermore, the cartridge can be removed from the press, for example replaced with a cartridge with cylinders of different sizes, and can be quickly and easily entered into the correct job setting position. In this way, various changes can be made to the press with minimal downtime.

One embodiment of the apparatus for moving the blanket cylinders 43 and 44 to a position that is in contact with or without the roll is shown in FIG. Where the solid line mark is the position when the cylinder is in the print job and the dashed line is the position when it is not. One blanket cylinder 44 is pressurized to contact the accompanying plate cylinder 46 and the gears 79 and 80 of FIG. 3 and the other blanket cylinder 43 (rolls) is clamped between the blanket cylinders 43 and 44. To ensure good contact for printing). The blanket cylinder 43 eventually presses the plate cylinder 45. In general, the mounting of the blanket cylinders 43 and 44 affords some margin, so that when the blanket cylinder 44 is pressurized to contact an adjacent cylinder, both the cylinders and the interoperable blankets with both cylinders 43 and 44 are involved. In response to the contact pressure on the cylinder, it is automatically positioned at the correct printing position.

In order to engage the blanket cylinders 43 and 44 with each other, one of them (44 in FIG. 8) is movable so that its axis moves between positions B and A. This is achieved by mounting the end of the support into which the cylinder enters the groove, one end of which corresponds to the cylinder axis at position (B) and the other end slightly from the side of the groove when the cylinder axis is at position (A). It is formed to have a gap of. The cylinder shaft is pressed toward the position B by the load plunger 140 when no printing operation is performed, so that the blanket cylinder 44 is in the position indicated by the dotted line, and the corresponding plate cylinder 46 and the other blanket cylinder ( 43) Out of contact with

The other blanket cylinder 43 is supported on a pivot support 141 which allows the cylinder axis to move along a limiting arc in an oversized hole (not shown). The boundary of this hole serves to limit the amount of movement from the plate cylinder 45 without affecting the position of the shaft when the blanket cylinder 43 is in contact with the plate cylinder 45. This is due to the fact that the cylinder 43 follows the other cylinder 44 but can be kept out of contact with the cylinder 44 so that when the blanket cylinder 44 moves to position B, It is possible to provide a gap for opening between the plate cylinders 45 and a gap between the two blanket cylinders 43 and 44. Similar effects can be achieved by mounting the support of the blanket cylinder 43 in a groove that allows it to contact the plate cylinder 45 and restricts its separation from the plate cylinder 45. If there is no means for maintaining the blanket cylinder 43 in contact with the plate cylinder 45, the blanket cylinder 43 is spaced apart on the pivot support 141 by the separation force generated by gravity. However, the separation force is not required to exceed the initial value. If the gravity (or other force) on the cylinder 43 exceeds this predetermined value, the separation force is reduced by the spring 12 or other eccentric means such as air cylinder actuation on the pivotal support 141.

In addition, as shown in FIG. 8, the blanket cylinder 44 may be mounted on a blanket 143 connected to the lever 144 pivoting at point 145. Here, when the lever 144 is moved to the position indicated by the solid line by the pneumatic device 146, a force is applied to the blanket cylinder 44 so that the axis of the cylinder 44 is moved from the position of (B) against the pressing force of the plunger 140. To the position of (A). This position A is a printing position. The blanket cylinder 44 is in close contact with the plate cylinder 46 and in contact with another blanket cylinder 43 to move the cylinder 43 in contact with its plate cylinder 45. The exact positioning and pressure setting is determined by the reaction of the blanket cylinder to the adjacent cylinder and the control force to move the blanket cylinder to the desired position, at which point it is no longer determined by the influence of the groove or opening for mounting the cylinder. .

Thus means for moving one of the cylinders to set and release at the printing position, for driving the other cylinder beyond the limit controlled by the restriction of the groove and opening in the "off" position by the reaction of force in the "on" position. By providing means, the print job can be released and reset quickly and simply. This is true even if another cartridge is installed in the press. In other words, the device takes power and allows it to set itself up. Ideally, the cylinder should operate on a continuous plane, which is performed by the cylinder bearer described later.

Therefore, while the printing press described with reference to FIGS. 2 to 7 can continuously print, the cartridge can be easily replaced by quickly and easily establishing the required precise installation. This characteristic is very important in minimizing downtime. The apparatus shown in FIG. 2 is particularly applicable to printing jobs of a single color (including black). In addition, this may be a problem in having a common ink and wet water train, and there is a problem that a large number of cartridges and inks and wet water trains may be required, but are usefully applied for printing colors.

9 and 10 show the construction of a cylinder which is particularly useful in the present invention. Each cylinder has a core 150 having a predetermined size so that rim devices of different thicknesses can be fitted as needed. 9 shows a cylinder with a relatively thick rim device 151, while FIG. 10 shows a cylinder with a relatively thin rim device 152. By changing the rim devices 151 and 152 to one another, the effective diameter of the cylinder can be changed and there is no need to remove the core 150 from the press. The rim devices 151 and 152 are corrosion resistant (otherwise acidic rubber in the wet water fluid causes corrosion) and the rim device can be removed so that it can be easily maintained and preserved.

As shown in FIGS. 9 and 10, the rim devices 151, 152 support the printing plate 153 connected to itself by the clips 154, 155, which clips 154, 155 support the printing plate 153 around the cylinder. Allow to grow. 9 and 10 also show an end ring 156 and a clamp 157 at the end of the cylinder, which are for supporting the rim devices 151 and 152 on the core 150. The ring 156 acts as a bearing to ensure smooth rotation of the cylinder as described above. What is important here is that the ring 156 is slightly thicker than the rim devices 151 and 152 so that the outer circumferential surface of the ring 156 in the changing direction exactly matches the outer circumferential surface of the printing plate 153.
