2. Description of the Related Art With the recent increase in the size of electronic parts, the elastic plate is necessarily increased in size (for example, size: about 1000 mm in the winding direction, about 800 mm in the width direction; weight: 1.0).
Taking into account Kg and two plate holders, the total weight is about 3.4 Kg (larger weight than a normal printing plate). When the elastic plate is wound around the plate cylinder of the printing roll 14 and removed, a person lifts the first plate holder of the elastic plate and another person holds the second plate holder of the second plate of the printing roll. It is necessary to hook and fix the chuck means 15 and rotate the printing roll (hereinafter, an elastic plate that causes such inconvenience is referred to as a "large elastic plate").

For this reason, in the film forming apparatus, at least two persons (hereinafter referred to as Party A and Party B) wind the large elastic plate 1 around the plate cylinder of the printing roll 14. The conventional unwinding operation of the large elastic plate will be described in detail below with reference to FIG. First, the instep climbs on the base 10 of the film forming apparatus, stands up with the first plate holder attached to the large elastic plate 1 and hangs the second plate holder and the large elastic plate 1 by gravity. The second plate holder is formed on the plate cylinder of the printing roll 14 while maintaining the suspended state.
It is brought close to the chuck means 15. Next, the second party manually hooks and fixes the second plate holder on the second chuck means 15 formed on the plate cylinder of the printing roll 14. Next, after confirming that the fixing is completed, the second party rotates the printing roll 14 at a low speed with a motor to gradually wind the large elastic plate 1 around the plate cylinder of the printing roll 14.
At this time, the upper is kept while the large elastic plate 1 is wound around the plate cylinder of the printing roll 14, that is, until the first plate holder approaches the first chuck means 150 formed on the plate cylinder of the printing roll 14, While the first plate holder and the large elastic plate 1 are being lifted, it is necessary to apply force to the arm so that the large elastic plate 1 can maintain a certain constant tension. During this period, the instep will work while gradually changing from the standing state to the mid-waist state to the leaning state. Next, the rotation of the printing roll advances, and the first plate holder is formed on the plate cylinder of the printing roll 14 as the first plate holder 1.
When approaching 50, B stops the rotation of the printing roll 14 and hooks the first plate holder 2 on the first chuck means 150 formed on the plate cylinder of the printing roll 14 to fix it. After confirming the completion of fixation, the instep releases the 1st edition holder. This completes the winding.

The large elastic plate 1 is attached to the printing roll 14
When removing from the plate cylinder, at least two people must do it. First, the instep climbs on the base 10 of the film forming apparatus, and holds the first plate holder 2 attached to the large elastic plate 1 by bending forward. Oto is the 1st edition holder 2 printing roll 1
It is detached from the first chuck means 150 formed on the plate cylinder of No. 4. Next, after confirming the removal, the second party rotates the printing roll 14 at a low speed with a motor in the direction opposite to that at the time of winding. At this time, the instep keeps the first plate holder 2 lifted up so that the large elastic plate 1 does not hang down due to gravity and contact the film forming apparatus, until the large elastic plate 1 is entirely peeled from the plate cylinder of the printing roll 14. Continue to lift the first plate holder 2 and the large elastic plate 1. During this period, the instep is to be worked while gradually changing from the forward leaning state to the middle waist state to the standing up state. Next, the large elastic plate 1 is entirely covered with the printing roll 14.
When the second roll holder 3 is peeled off from the plate cylinder, the second roll holder 3 stops the rotation of the printing roll 14 and manually removes the second plate holder 3 from the second chuck means 15 formed on the plate cylinder of the printing roll 14. The upper is a large elastic plate 1, a first plate holder 150 and a second plate holder 15
All will be suspended only by their own power. with this,
Removal is complete.

[0006]

The conventional technique has the following problems. (1) A person who holds one plate holder of a large elastic plate and lifts it on the film forming apparatus and a person who hooks the other plate holder on the chuck means of the printing roll to fix the plate holder are required separately. It takes much time and is very inefficient. (2) It is necessary to pull up the large elastic plate so that a certain tension is applied to the large elastic plate so that the large elastic plate does not undulate until it is completely wrapped. Since it is heavy, a heavy burden is placed on a person who holds one plate holder of a large elastic plate and lifts it on the film forming apparatus. Further, since the large elastic plate has a large area and the plate holder is long, a person who lifts the large elastic plate must spread his arms to hold the plate holder, which further amplifies the weight feeling of the large elastic plate and the plate holder. (A) Therefore, unless careful work is performed according to a predetermined manual, there is a risk that the large elastic plate may be dropped onto the printing roll and the large elastic plate or the film forming apparatus may be damaged. (B) Moreover, the plate holder is liable to shake, and the plate holder cannot be kept horizontal at all times, and when the large elastic plate is wound around the plate cylinder of the printing roll, the tension applied to the large elastic plate is uniform over the entire surface. In addition, it is difficult to lower the large elastic plate in synchronism with the rotation of the printing roll while keeping it constant. Therefore, the large elastic plate wound around the plate cylinder is easily wavy. (3) Since a person has to hold one of the plate holders with his / her hands until the large elastic plate is completely wrapped around the printing roll plate cylinder, the large elastic plate with dust, oil or sweat You will grab the holder for a long time. Therefore, dust, oil, and sweat adhere to the large elastic plate, and the large elastic plate is easily soiled. (4) The instep that holds the first plate holder and hangs the second plate holder moves in parallel with the large elastic plate while hanging the second plate holder to bring the second plate holder closer to the second chuck means. However, the heavy elastic plate and the first and second plate holders must be moved in parallel while bearing the total weight. In addition, since the first plate holder is supported right above the printing roll to support it, the printing roll cannot stand in a stable manner because of the hindrance. In this way, due to the movement of heavy objects and poor scaffolding,
It is difficult to move the second plate holder to the correct position of the second chuck means.

[0007]

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 12, the large elastic plate winding and removing assisting device of the present invention is
A support device used when a large elastic plate having a plate holder and a second plate holder attached at both ends is wound around a plate cylinder of a printing roll and removed, and a base plate located above the printing roll and a base plate. A rotary arm portion that is rotatable around one end attached to the rotary arm portion; a holding portion that is rotatably attached to the other end of the rotary arm portion to hold the first plate holder of the large elastic plate; When the large elastic plate is wound around the plate cylinder of the printing roll, the tension applied to the large elastic plate is kept constant while the rotating arm part of the rotating arm is synchronized with the rotation of the printing roll. The other end of the rotation arm descends while rotating to bring the holding part closer to the plate cylinder of the printing roll, and when the large elastic plate is removed from the plate cylinder of the printing roll, the other end of the rotating arm part is substantially synchronized with the rotation of the printing roll. Rotate Reluctant rise to the plate cylinder of the printing roll is possible to detach the holder.

(Description of Large Elastic Plate) The large elastic plate 1 will be described. The large elastic plate 1 is a so-called elastic relief plate, which is a soft plate made of rubber or nylon resin and has convex portions 17 formed on the surface in a desired pattern.
Alternatively, it may be an intaglio plate having a pattern of recesses on the surface, or a planographic plate. As the large elastic plate 1, one having a winding direction of about 1040 mm, a width direction of about 795 mm and a weight of about 1.0 Kg (2.4 Kg with two plate holders),
Winding direction is about 1158 mm, width direction is about 935 mm,
Weight of about 1.3Kg (2.8K with 2 plate holders
There is g). The large elastic plate 1 has horizontally long plate holders attached to both ends thereof. The plate holder, which is hooked and held by the holding portion 7 of the large-sized elastic plate winding and removing assisting device, is referred to as the first plate holder 2, and is hooked on the second chuck means 15 formed on the plate cylinder of the printing roll 14. The plate holder to be fixed is referred to as a second plate holder 3. As the first plate holder 2, there is one in which two types of holes are formed. An assisting device holding hole 4 for catching by the holding part 7 of the large elastic plate winding and removing assisting device, and a chuck hole 5 for catching and fixing it on the chuck means formed on the plate cylinder of the printing roll 14. . The assisting device holding hole 4 and the chuck hole 5 are holes that are formed side by side at intervals such as in the longitudinal direction of the plate holder. The support device holding hole 4 may be formed in only one place in the central portion of the first plate holder (see FIG. 4), or may be formed in two or more places. In the case of only one place, the large elastic plate 1 is suspended in a pendulum shape on the holding portion 7, and the free shaking of the first plate holder 2 absorbs wrinkles and waviness that are likely to occur in the large elastic plate 1. However, it is effective because it can be wound around the plate cylinder of the printing roll 14 in a well-balanced manner. Since the second plate holder 3 is not held by the holding portion 7 of the large elastic plate winding and removing assisting device, it is hooked and fixed by the second chuck means 15 formed on the plate cylinder of the printing roll 14. Only the chuck holes 5 are formed (see FIG. 4). Large elastic plate 1
Is wound around the plate cylinder of a cylindrical printing roll 14, printing ink is attached to the top of the convex portion 17, and the convex portion 17 comes into contact with the surface of the material to be printed.
Printing is performed by transferring ink from the top of No. 7 to the surface of the printing medium.

The printing roll 14 around which the large elastic plate 1 is wound is, for example, a printing roll of a film forming apparatus. The film forming device is a device for forming a polymer material or an inorganic material used for electronic parts such as a liquid crystal alignment film in a pattern in a thin film or a thick film, and an intaglio roll having a large number of ink cells and ink in the ink cells. Ink supply device for filling, printing roll in which an elastic plate on which the ink of the intaglio roll is transferred is wrapped around the plate cylinder, a printing table for fixing the substrate to which the ink of the printing roll is transferred, and ink cells of the intaglio roll A film forming apparatus comprising a doctor blade for surely filling the inside with ink. Printing roll 14
In order to fix the second plate holder 15 and the first plate holder 150 to the second chuck unit 15 and the first chuck unit 150 formed on the plate cylinder, screws, electromagnets, iron claw pressing, etc. are used.

(Description of Base Plate) The base plate 9 is located above the printing roll 14. The base plate 9 may extend downward from the ceiling beam of the factory where the film forming apparatus is installed. Alternatively, the base may be installed at a location apart from the film forming apparatus and extended from there to above the printing roll 14. In the embodiment of FIG. 4, the base plate 9 is
At a distance wider than the longitudinal width of the first plate holder 2, 2
One base plate 9 is installed. This is because each of the two rotating arm portions 6 is attached. The material of the base plate 9 is aluminum or the like. Since the rotating arm portion 6 and large-sized elastic plates and large-sized objects such as the first plate holder and the second plate holder must be supported, those having high rigidity are preferable.

(Description of Movable Turn Roll) On the base plate 9, a movable turn roll 21 for making an angle in the tension direction of the large elastic plate while the rotating arm portion 6 is rotating is provided with a rod 22 extending from the base plate 9. It may be installed at the tip of. Since the movable turn roll 21 is installed, the large elastic plate 1 from the first plate holder 2 (that is, the tip of the rotary arm part 6) to the movable turn roll 21 is moved according to the rotation angle of the rotary arm part 6. The tension direction and the tension direction of the large elastic plate 1 from the movable turn roll 21 to the second plate holder can be made different. In the embodiment shown in FIG. 9, a movable turn roll 21 is installed at the tip of a rod 22 extending from the base plate 9, and the large elastic plate 1 is pressed rightward. In the series of processes shown in FIGS.
From (a) to (c), the movable turn roll 21
By adjusting the pressing force on the large elastic plate 1 by the air cylinder or the like, the angles θ1, θ2, θ3 formed by the movable arm portion 6 and the large elastic plate 1 are always about irrespective of the rotating state of the movable turn roll 21. It can be kept at 90 degrees. By doing so, the tensions t1, t2, t3 applied to the large elastic plate 1 can be maintained substantially constant at all times. Therefore, the large elastic plate 1 is wound around the plate cylinder of the printing roll 14 with a constant tension. There is an advantage that it can be attached. Further, by installing the movable turn roll 21 so as to reach the lower right portion of the rotating arm portion 6, it is possible to prevent the rotating arm portion 6 from accidentally turning counterclockwise.

(Explanation of Rotating Arm Unit) Rotating Arm Unit 6
Is rotatable about a rotary shaft 13 attached to the base plate 9. The material of the rotating arm portion 6 is preferably lightweight and highly rigid such as aluminum. This is because the movement of the rotary arm portion 6 can be performed by a low-power drive source. The rotation axis of the rotating arm portion 6 with respect to the base plate 9 can be formed at any position in the longitudinal direction or the width direction of the rotating arm portion 6. Specifications (Print roll 1
Since the size of the diameter of 4 and the length of the base plate 9 may vary, it is necessary to adjust the radius of gyration of the rotary arm 6 to vary the circular orbit of the first plate holder formed. Is. The rotation of the rotary arm portion 6 is not controlled by the free rotation but is controlled by the air cylinder 11 or a spring. The reason for controlling is to wrap the plate roll of the printing roll without wrinkles or waviness and prevent the large elastic plate from slackening more than necessary and coming into contact with an adjacent machine or the ground. It is also possible to control the tension of the large elastic plate 1 so as to keep it constant.

Since the rotary arm portion 6 makes a rotary motion, it can move not only vertically but also horizontally. For this reason, when fixing the second plate holder to one of the chuck means, it is possible to safely work without worrying about the weight or scaffolding of a large elastic plate or the like. Further, the second plate holder can be automatically moved to the vicinity of the chuck means. Therefore, the distance for manually moving the second plate holder is completely unnecessary, or if necessary, it is extremely short and efficient. Further, when fixing the first plate holder to the other chuck means, the first plate holder can be moved to the vicinity of the chuck means. For this reason, the distance for manually moving the first plate holder is completely unnecessary, or if necessary, it is extremely short and efficient.

In the embodiment shown in FIG. 4, the rotary arm portion 6 is composed of two rotary arm portion main bodies 61 and 62 and a connecting member 60 connecting them. Two rotating arms 6
Each of 1, 62 is rotatably attached to each of the two base plates 9. A holding portion 7, which will be described later, is rotatably attached to the connecting member 60 at approximately the center of the connecting member 60.

(Description of Holding Unit) In FIG. 4, the holding unit 7 is a member rotatably attached to the connecting member 60 for holding the first plate holder 2 of the large elastic plate 1. As the holding portion 7, for example, a metal hook-shaped hooking portion 70,
For example, a rod-shaped member is provided with a notch at the tip. The reason why the support device holding hole 4 of the first plate holder 2 is prevented from slipping off is that the hook-like shape and the notch portion are provided. The hook portion may be immovable, or may be a movable one that is moved by an air cylinder or the like to tighten the inner wall of the support device holding hole 4 of the first plate holder 2 of the large elastic plate 1. The holding portion 7 may be formed in only one place or in two or more places. The holding portion 7 is a connecting member 6.
Since it is rotatably attached to 0, the large elastic plate 1 and the first plate holder 2 can always be parallel to each other regardless of the rotation angle of the rotating arm portion 6 (FIG. 1, FIG. (See FIGS. 2, 3, and 9). Hooking part 7 of holding part 7
Two or more zeros may be attached, but in the embodiment of FIG. 4, the hook portion 70 of the holding portion 7 is provided only at one central portion of the connecting member 60 that connects the two rotating arm portion bodies 61 and 62. It is installed. By making the holding part 7 one place,
If the large elastic plate 1 is allowed to shake freely, the large elastic plate 1 does not wrinkle due to the free shaking of the large elastic plate 1 absorbing the distortion of the large elastic plate during winding. Because it can be wrapped around. The holding portion 7 may be a magnetic type or a vacuum suction type.

(Description of Drive Unit) The drive unit controls the rotation of the rotary arm unit 6. The drive unit can rotate while maintaining a constant tension applied to the large elastic plate 1. The air cylinder 1 is used as the drive unit.
By evacuating the air inside 1, the pushing rod 1
2 can be projected or retracted. The rotation speed of the rotary arm unit 6 is controlled by controlling the amount of air discharged from the air cylinder 11 per unit time. The drive unit may rotate the rotating arm unit 6 by hydraulic pressure, water pressure, or a motor.

In the embodiment shown in FIGS. 5 to 8, the rotation of the rotary arm portion 6 is controlled by using the air cylinder 11. The tip of the pushing rod 12 of the air cylinder 11 is rotatably attached to the rotating arm portion 6, and the main body of the air cylinder 11 is attached to rotate with respect to the base plate 9. When the protrusion amount of the pushing rod is small, the rotary arm portion 6 is positioned with one end to which the connecting member is attached facing upward (see FIG. 5).
When the amount of protrusion of the pushing rod 12 is increased, one end of the rotary arm portion 6 to which the connecting member is attached rotates rightward about the rotary shaft 13 (see FIG. 6). At the time of FIG. 6, the amount of protrusion of the pushing rod 12 becomes almost maximum. When the protrusion amount of the pushing rod is further reduced, one end of the rotating arm portion 6 to which the connecting member is attached further rotates rightward about the rotating shaft 13 (see FIG. 7). FIG. 7 shows a state in which the state of FIG. 5 is rotated by 180 ° or more through the state of FIG. Once the amount of protrusion of the push rod 12 is increased,
Next, by reducing the size, the state of FIG. 7 is returned to the state of FIG. 5 through the state of FIG.

On the other hand, in the embodiment shown in FIGS. 11 to 12, when the protruding amount of the pushing rod is large, the rotary arm portion 6 is positioned with one end to which the connecting member is attached facing upward (FIG. 11). When the amount of protrusion of the pushing rod 12 is reduced, one end of the rotary arm portion 6 to which the connecting member is attached rotates rightward about the rotary shaft 13 (see FIG. 12). At the time of FIG. 12, the protrusion amount of the pushing rod 12 becomes the minimum. By continuing to increase the amount of protrusion of the pushing rod 12, the state of FIG. 12 returns to the state of FIG. 11. The protrusion amount of the push-out rod 12 of the air cylinder 11 can be set so that the rotational force of the printing roll 14 is transmitted via the large elastic plate 1 and fluctuates, and also fluctuates independently of the rotational force of the printing roll. You can also do so. 11 to 12, the print roll 14
If there is no rotational force of, the state automatically returns to the state of FIG. Extruding rod 1 for air cylinder 11
This is because the force is always applied in the direction in which 2 is projected.

In the embodiments of FIGS. 5 to 8, the amount of protrusion of the tip of the pushing rod 12 of the air cylinder 11 changes from large to small to large, but in the embodiments of FIGS. 11 to 12, from large to small. It is a one-way street.

(Operation of the present invention) When the rotating arm portion 6 winds the large elastic plate 1 around the plate cylinder of the printing roll 14, the tension applied to the large elastic plate 1 is kept constant while the rotation of the printing roll 14 is substantially constant. When the elastic plate is removed from the plate cylinder of the printing roll 14, it is possible to descend while rotating in synchronism, and to rise while rotating substantially in synchronism with the rotation of the printing roll 14. An example of a case in which the large elastic plate 1 is unwound and unwound by rotating the same in synchronization with the rotation of the printing roll 14 while keeping the tension applied to the large elastic plate 1 constant and lowering or raising it will be described. To do.

In the case of winding, the instep adjusts the protrusion amount of the pushing rod of the air cylinder to rotate the rotating arm portion 6 slightly to the right from the 12 o'clock position and stop it. The support device holding hole 4 of the first plate holder 2 of the large elastic plate 1 is hooked and fixed to the hook portion 70 of the holding portion 7 of the rotating arm portion 6, and the second plate holder 3 is hung by gravity. 1).
By rotating the rotating arm portion 6 to the right, the holding portion 7 of the rotating arm portion moves to the right or downward, so that it is separated from the vertical position of the base plate 9 to the left and right by the maximum length of the rotating arm portion 6. At a position, and at a position that is a maximum distance from the rotating shaft 13 of the rotating arm portion 6 and is vertically separated by the length of the rotating arm portion 6,
Since the first plate holder 2 can be hooked on the rotating arm portion 6 to be suspended, the second plate holder 3 can be securely and reliably fixed to and removed from the second chuck means 15 with a small force. Since the holding portion 7 is rotatably attached to the connecting member 60, no matter how the rotation arm portion 6 rotates, the first plate holder 2 and the large elastic plate 1 will not be bent excessively. Without doing so, it is possible to always maintain the parallel relationship according to the direction of the tension applied to the large elastic plate 1. Next, after confirming the completion of hooking, the instep adjusts the protrusion amount of the pushing rod 12 of the air cylinder 11, rotates the rotating arm portion 6 to the left, and suspends the second rod.
The plate holder 2 is moved horizontally to approach the second chuck means 15 of the printing roll 14 (see FIG. 8). The upper does not need to lift or horizontally move the second plate holder 3, and the chuck hole 5 of the second plate holder 3 is attached to the second chuck means 15 formed on the plate cylinder of the printing roll 14 by a hand or a magnet. All you have to do is hook it and fix it. next,
After confirming the completion of fixing, the printing roll 14 is rotated at a low speed by a motor, and the large elastic plate 1 is gradually wound around the plate cylinder of the printing roll 14. The rotary arm unit 6 holding the first plate holder 2 automatically maintains an appropriate tension by controlling the air exhaust amount in the air cylinder 11 calculated based on the rotation speed data of the printing roll 14. While the first plate holder 2 of the large elastic plate 1 is attached to the printing roll 14,
While continuing to descend until it approaches the first chuck means 150 formed on the plate cylinder (see FIGS. 2 and 6). The tension applied to the large elastic plate 1 is, for example, about 1040 mm in the winding direction and about 795 in the width direction.
mm, weight of about 1.0 kg (2.4 kg with two plate holders) is fixed to the printing roll, and the tip of the spring scale is hooked on the second plate holder 3 and hung. When measured by rotating the down printing roll 14 at a low speed, it is a constant value of 2 to 5 kg. When the rotation of the printing roll 14 is stopped, the descent of the rotating arm portion 6 also stops. Next, the rotation of the rotating arm portion 6 advances, and the large elastic plate 1
When the first plate holder 2 comes close to the first chuck means 150 formed on the plate cylinder of the printing roll 14, the instep stops the rotation of the printing roll 14 and supports the first plate holder 2 from the holding portion 7 of the supporting device. The device holding hole 4 is removed, and the chuck hole 5 of the first plate holder 2 is hooked and fixed to the first chuck means 150 formed on the plate cylinder of the printing roll 14 (see FIG. 3). In addition, in FIG. 7, the holding member (not shown) of the rotating arm reaches the left side of the position directly below the base plate 9. By rotating the rotary arm unit 6 to the right,
Since the first plate holder 2 can be moved to the left of the vertical position of the base plate by the length of the maximum rotation arm, the first plate holder 2 can be securely and reliably hooked and fixed with a small force. This completes the winding.

In the case of removal, the instep removes the chuck hole 5 of the first plate holder 2 of the large elastic plate 1 from the first chuck means 150 formed on the plate cylinder of the printing roll 14,
The supporting device holding hole 4 of the plate holder 2 is hooked on the holding portion 7 of the rotating arm portion 6 of the supporting device. Next, after confirming the fixation, the former rotates the printing roll 14 at a low speed with a motor in the direction opposite to that at the time of winding. The rotating arm portion 6 holding the first plate holder 2 automatically maintains an appropriate tension by controlling the amount of air pressure in the air cylinder 11 calculated based on the data of the number of rotations of the printing roll 14. While continuing to rise, the large elastic plate 1 does not hang down due to gravity and come into contact with the film forming device or the ground. next,
With all of the large elastic plate 1 peeled off from the plate cylinder of the printing roll 14, the instep stopped the rotation of the printing roll 14 and the chuck holes 5 of the second plate holder 3 were formed in the plate cylinder of the printing roll 14. Remove from the second chuck means 15. This completes the removal. The large elastic plate 1 is suspended by the supporting device, and the supporting device holding hole 4 of the large elastic plate 1 is removed from the holding portion 7 of the rotating arm portion 6 and replaced with another large elastic plate 1.

The large-sized elastic plate winding and removing support device of the present invention has the following effects because it has the above-described structure. (1) It is not necessary to have a person to lift a large elastic plate on the film forming device when winding and removing the printing roll from the plate cylinder.
It is very efficient with no human labor. (2) The operator is not weighted. (A) Therefore, the large elastic plate is not dropped on the printing roll, and there is no risk of damaging the large elastic plate or the film forming apparatus. (B) Further, since the plate holder is mechanically lowered by the large elastic plate winding and removing support device, the large elastic plate is less likely to shake, and the plate holder can be kept horizontal at all times. When the large elastic plate is wound around the cylinder, the tension applied to the large elastic plate can be maintained at a uniform and constant numerical value over the entire surface. Therefore, the large elastic plate does not wind around the plate cylinder. (3) It is not necessary to hold one plate holder by hand until the large elastic plate is completely wrapped around the printing roll plate cylinder, so hold the plate holder with dust, oil, or sweat. I don't have to catch time. Therefore, dust, oil, and sweat that are scattered do not adhere to the large elastic plate and the large elastic plate does not easily become dirty. (4) Since it is mechanized by using the rotating arm portion, the second plate holder can be moved to an accurate position of the second chuck means when the large elastic plate is wound around the plate cylinder of the printing roll.
