[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing a thin film forming elastic plate to a printing roll plate cylinder while pressing the plate holder of the thin film forming elastic plate against the printing roll plate cylinder. The present invention relates to a printing roll with an elastic plate automatic chuck device that can easily pull the elastic plate to prevent wrinkles from occurring.

As an apparatus for forming a polymer thin film pattern used for electronic parts such as a liquid crystal alignment film, for example, an intaglio roll A having a large number of ink cells and an ink supply means B having a doctor blade B2 for filling the ink cells with ink. A thin film formation comprising a printing roll C having a thin film forming elastic plate E on the plate cylinder to which the ink of the intaglio roll A is transferred, and a printing table D for fixing a printing medium D2 to which the ink of the printing roll C is transferred Although the device is known (Fig. 1
0), the printing roll with the elastic plate automatic chuck device of the present invention is suitable for use in such a thin film forming apparatus.

[0003]

2. Description of the Related Art As a fixing device for an elastic plate for forming a thin film used in such a thin film forming device, a printing roll for inserting rotary screws into both ends of the elastic plate is disclosed in the invention of the applicant of the present application. Surface of a printing roll plate cylinder provided with a thin film forming elastic plate to which a plate holder having a chuck hole is attached, a hook portion having a rotary fixing screw, and a tension portion having a rotary tension screw There is one that is installed and removed (Japanese Patent Application No. 3-348683).

That is, the printing roll chuck hole of one of the plate holders attached to the elastic plate is manually inserted into the fixing screw of the hook portion, and the fixing screw is fixed by the human hand, and the other is fixed. The printing roll chuck hole of the plate holder is also manually inserted into the tensioning screw of the tension part, and the tensioning screw is moved by hand to move the tensioning part to tension the elastic plate, An elastic plate is attached to the body. In addition, to remove the elastic plate from the printing roll plate cylinder, loosen the tension applied to the elastic plate by rotating the tension part's tensioning screw with a person's hand and fixing it with a person's hand. The screw is loosened to release the fixation, the plate holder is manually pulled out from the chuck means of the printing roll plate cylinder, and the thin film forming elastic plate is removed from the printing roll plate cylinder.

[0005]

The conventional technique has the following problems. (1) The conventional chuck device has only a fixing screw and a pulling screw, so that the fixing screw can be tightened and loosened by using human hands, and the pulling device can be pulled by using human hands. Since it cannot be used unless the screw is turned to the left and right, it takes time and labor, and the efficiency of fixing and releasing the elastic plate for forming a thin film on the printing roll plate cylinder is poor.

(2) In the conventional chuck device, when fixing the thin film forming elastic plate to the printing roll plate cylinder, first, the operation of pressing the plate holder of the thin film forming elastic plate on the printing roll plate cylinder is performed. After the operation is completed by manually tightening the fixing screw and then the elastic plate is pulled on the printing roll plate cylinder to prevent wrinkles, the pulling screw is manually operated. This is done by rotating with your hands. If these two operations are not performed in this order, for example, the elastic plate may be pulled while the plate holder is floating from the printing roll plate cylinder, or the rotary screw cannot be fitted into the printing roll chuck hole of the plate holder. Inconvenience occurs. Therefore, when fixing the thin film forming elastic plate to the printing roll plate cylinder, it is necessary to perform the operation of rotating the screw by hand twice while considering the order of rotating the screw. It is troublesome and inefficient to fix the elastic plate for thin film formation.

Further, when releasing the elastic plate for forming a thin film, first, the operation of loosening the tension applied to the elastic plate is carried out by rotating the pulling screw manually. After completion, the operation of pressing the plate holder against the printing roll plate cylinder is performed by manually tightening the rotary screw. If these two operations are not performed in this order, for example, the inconvenience that the rotary screw cannot be pulled out from the printing roll chuck hole of the plate holder occurs. Therefore, even when the elastic plate for thin film formation is released, it is necessary to perform the operation of rotating the screw by hand twice while considering the order of rotating the screw. As described above, in the related art, fixing the thin film forming elastic plate to the printing roll plate cylinder,
Unlocking is very troublesome and inefficient.

(3) In the conventional chuck device, when the elastic plate is fixed to or released from the printing roll plate cylinder,
It cannot be used unless people enter and leave it.
Dust and dust flying from the ground adheres to the elastic plate. Also, dust and oil on the hands adhere to the elastic plate. Therefore, the film thickness of the ink transferred to the elastic plate becomes uneven and the ink is contaminated.

(4) In the conventional chuck device, both the pulling of the elastic plate and the pressing of the elastic plate against the printing roll plate cylinder must be performed manually, so that the chuck means and the printing roll are used. There is a risk of human injury being caught between the plate cylinder and other parts, resulting in injury. Therefore,
The present invention solves the above-mentioned drawbacks, and the elastic plate for forming a thin film can be fixed and unfixed on the printing roll plate cylinder without time and effort, and the elastic plate does not have the risk of being soiled or damaged. An object is to provide a printing roll with a plate automatic chuck device.

[0010]

In order to achieve the above-mentioned object, a printing roll with an elastic plate automatic chuck device of the present invention has a first plate holder provided with a first printing roll chuck hole and a tapered surface. A second plate holder provided with a second printing roll chuck hole on the outer inner wall, and a first chuck member having a claw portion in a printing roll to which elastic plates for thin film formation fixed to both ends of the elastic plate are fixed. A second chuck of the elastic plate for forming a thin film, and a first chuck unit configured to engage a claw portion of the first chuck member with an opening edge of a first printing roll chuck hole of the elastic plate for forming a thin film. A second chuck member having a claw portion with a tapered surface that matches the tapered surface of the printing roll chuck hole of the plate holder;
Second movement of the chuck member with respect to the printing roll plate cylinder
The second chuck means composed of a drive part is provided on the printing roll plate cylinder.

[0011]

In the printing roll with the elastic plate automatic chucking device of the present invention, in short, the first chuck means for engaging the claw portion of the first chuck member with the opening edge portion of the first printing roll chuck hole of the elastic plate for forming a thin film. And a second chuck means having a tapered surface corresponding to a tapered surface of the printing roll chuck hole of the second plate holder of the elastic plate for forming a thin film on the claw portion of the second chuck member, in the printing roll plate cylinder. Therefore, by simply hooking the printing roll chuck hole of the elastic plate for forming a thin film on the first chuck member and the second chuck member of the printing roll plate cylinder, the first driving unit and the second driving unit automatically fix and The fixation is released.

Further, the printing roll with the elastic plate automatic chuck device of the present invention fixes the thin film forming elastic plate as follows. As an example of an elastic plate for forming a thin film, a first plate holder and a second plate holder having a pair of printing roll chuck holes to be held and released by an automatic chuck means of a printing roll plate cylinder are elastic plates. There is an elastic plate for forming a thin film, which is attached to both ends of the second plate holder and has a tapered surface with an upward spread on the outer inner wall of the printing roll chuck hole of the second plate holder.

First, the claw portion of the chuck member is inserted into the printing roll chuck hole of the elastic plate for forming a thin film, and the second driving unit automatically moves the chuck member toward the outer side of the elastic plate, whereby the chuck member is moved. The tapered surface of the claw portion is pressed against the tapered surface of the inner wall of the printing roll chuck hole. By this pressing, the taper surface of the inner wall of the printing roll chuck hole is moved horizontally (see FIG. 1) from the chuck member.
The force is simultaneously applied in both the right direction) and the vertical direction (downward in FIG. 1) (see FIG. 1B). Therefore, only one operation of pressing the tapered surface of the chuck member against the tapered surface of the plate holder of the elastic plate simultaneously pulls the elastic plate and presses the elastic plate against the printing roll plate cylinder at the same time.

Since the pushed portion is the tapered surface 11, the force pushing the second plate holder 3 is decomposed into the downward force in FIG. 1 and the rightward force in FIG.

The downward force in FIG. 1 serves as a force for sandwiching the second plate holder 3 in cooperation with the mounting table 19 so that the printing roll plate cylinder C and the thin film forming elastic plate E are not displaced in the vertical direction. Fixed. The force to the right in FIG. 1 is a force to pull the elastic plate 1 to the right, and the printing roll plate cylinder C and the thin film forming elastic plate E are fixed so as not to be displaced in the horizontal direction.

The ratio of the decomposition of the downward force in FIG. 1 to the rightward force in FIG. 1 depends on the inclination of the taper surface 11 of the second printing roll chuck hole 81 of the second plate holder 3 and the taper surface 17 of the second chuck member 15. Depends on the degree of. For example, when the inclination is large, the ratio of the downward force in FIG. 1 is small, and the ratio of the downward force in FIG. 1 is large.

When the pushing force of the cylinder 24 is made larger than the repulsive force again, the first slider 21 moves leftward in FIG. 1 against the repulsive force of the compression spring, and the taper surface 17 of the second chuck member 15 is formed. The taper surface 11 of the second plate holder 3 is separated (see FIG. 1A).

Next, the first chuck means 12 will be described (see FIG. 3). The first chuck means 12 includes a mounting table 19, a first chuck member 25, and a first drive unit 26, and corresponds to the number of the first printing roll chuck holes 80 provided in the thin film forming elastic plate E. It is provided at a plurality of locations on the printing roll plate cylinder C.

The mounting table 19 is the first of the elastic plate E for forming a thin film.
