The tension adjusting roll, for preventing the roller from being bent and the film to be transferred from being damaged by a pressing force intensively applied to both ends of the roller for transferring the film to be transferred, enables first and second adjusting rolls to be integrally coupled to both ends of a iron core roll and enables a tension adjusting space to be formed between the iron core roll and the first and second adjusting rolls to partially absorb the pressing force intensively generated in both ends of the iron core roll while both ends of the first and second adjusting rolls are bent into the tension adjusting space to prevent the roller from being bent and the film to be transferred from being damaged.

Description

TENSION ADJUSTING ROLLER USING IN ATMOSPHERE "

The present invention relates to a tension control roll used in the air without being immersed in water or chemicals.

The roller includes a pipe formed to have a predetermined length and a shaft inserted and welded to both sides of the pipe. The LCD film is manufactured by using the film production apparatus equipped with the rollers described above.

When the polarizing film is sandwiched between the fixing roller and the pressing roller in the film producing apparatus, when the pressing means presses the pressing roller toward the fixing roller side, when the film is sandwiched between the rollers, And is transferred while being stretched to manufacture an LCD film.

In the case of the rollers used in the film production apparatus as described above, that is, the rollers used in the process for producing various functional films, the longer the length of the high pressure or the roller is, in the course of laminating a plurality of films or coating the film A plurality of rollers (pressure rollers and fixing rollers) opposed to each other are concentrated at both ends of the pressure rollers in the case of the pressure rollers whose both ends are pressed, The load applied to the film member being transported is also non-uniformly generated, resulting in a problem that the film member is broken.

In order to solve this problem, there has been developed a technique of inserting a roll of cushion material into both ends of a roller. However, in the case of a structure in which a roll having a cushion is inserted into both ends of the roller, When a plurality of rollers for conveying a film are used in a process of causing a film to be coated with a chemical by keeping the films passing between them in a semi-submerged state in various liquids (water, chemicals, etc.) The elastic force through the cushion roll was insufficient and it was impossible to prevent the bending phenomenon at both ends of the roller.

It is an object of the present invention to provide a tension control roll used in the atmosphere in which a roller for transferring a film to be transferred is not immersed in a separate liquid phase together with a film, A tension adjusting space is separately formed between the iron core roll and the first and second adjusting rolls so that a part of the pressing force generated at both ends of the iron core roll The first and second adjusting rolls are absorbed while being bent into the tension adjusting space so that a constant pressing force can be maintained in the width direction of the film and the outer cover can be prevented from flowing into the tension adjusting space Which is used in the atmosphere.

Other objects and advantages of the present invention will be described hereinafter and will be understood by the embodiments of the present invention. Further, the objects and advantages of the present invention can be realized by the means and the combination shown in the claims.

As a means for solving such a problem as described above, the present invention relates to a tension adjusting roll which is not immersed in a liquid phase of water or chemical together with a film to be transported and which is used in the atmosphere to transport the film to be transported An iron core roll (10) having protrusions (11) protruding outwardly at an outer peripheral edge stop; The iron core rolls 10 are tightened from both ends of the iron core 10 to the protrusions 11 and are integrally welded to each other at the outer circumferences of the protrusions 11, By forming the space 30, when a pressing force is applied to both end portions of the iron core roll 10, it is bent into the tension adjusting space 30 and absorbs a part of the pressing force concentrated on both ends of the iron core roll 10, First and second adjustment rolls (41, 42) for making the pressing force applied to the target film (F) uniform over the entire width direction; An outer roll (50) coupled to the outer periphery of the first and second control rolls (41, 42); .

As described above, the present invention has an effect of absorbing a partial pressing force exerted intensively on both ends of the roller and preventing a bending phenomenon in which the roller is bent as the length of the roller becomes longer.

In addition, according to the present invention, the tension can be adjusted by the width of the tension adjusting space regardless of the predetermined pressing force, thereby eliminating the need for a separate preliminary work for adjusting the tension.

Further, by preventing the rollers from warping, there is an effect that the film to be transported is transported with uniform pressure throughout the width direction.

In addition, the present invention provides a uniform pressure to the film to be transported in the width direction and transporting the film, thereby preventing defects from occurring in the film member due to uneven pressure.

Further, the present invention is not only usable in the atmosphere, but also has an effect that it can be used in a process of transferring a film to a liquid film by a roller and a film to be transferred.

To this end, according to an embodiment of the present invention, there is provided a tension adjusting roll for transferring a film F to be transferred, which is used in the air without being immersed in a liquid phase of water or chemical together with the film F to be transferred, An iron core roll (10) formed with protrusions (11) protruding outwardly at a stop; The iron core rolls 10 are tightened from both ends of the iron core 10 to the protrusions 11 and are integrally welded to each other at the outer circumferences of the protrusions 11, By forming the space 30, when a pressing force is applied to both end portions of the iron core roll 10, it is bent into the tension adjusting space 30 and absorbs a part of the pressing force concentrated on both ends of the iron core roll 10, First and second adjustment rolls (41, 42) for making the pressing force applied to the target film (F) uniform over the entire width direction; An outer roll (50) coupled to the outer periphery of the first and second control rolls (41, 42); .

The tension adjusting space 30 may be fixed to the outer side of the iron core roll 10 in a disc shape by closing the tension adjusting space 30 so as to be protected from external foreign substances, An outer cover 60 formed into a circular tube shape to be inserted corresponding to the outer cover 60; Is further provided.

The outer roll 50 may be formed of any one of metal, paint, rubber, silicone, urethane, ceramic, and epoxy.

Hereinafter, a tension adjusting roll 100 used in the air according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6. FIG.

The tension control roll used in the atmosphere of the present invention includes an iron core roll 10, first and second adjustment rolls 41 and 42, an outer roll 50 and an outer cover 60.

The rotary shaft 20 is connected to both ends of the iron core roll 10 so as to be able to transmit power by means of a power transmitting means for rotating the iron core roll 10, Respectively, so that both ends of the iron core roll 10 are sealed.

In addition, the outer peripheral edge of the iron core roll 10 forms a protruding portion 11 protruding outward, so that a step 12 is formed on both sides of the protruding portion 11 of the iron core roll 10 .

The first and second adjusting rolls 41 and 42 are each shaped like a circular tube having both open ends and an empty interior and are coupled to the outer periphery of the iron core roll 10 described above, The second adjusting roll 42 is engaged with the other end of the iron core roll 10 from the other end of the iron core roll 10 to the stop of the protruding portion 11.

That is, one end of the first adjusting roll 41 and one end of the second adjusting roll 42 are in surface contact with the outer circumference of the protruding portion 11, and the first and second adjusting rolls 41, 42 are formed in the shape of a ring on the outer peripheral edge of the end portion which is in contact with each other so that when the end portions of the first and second control rolls 41, 42 are in close contact with the outer peripheral edge of the projecting portion 11, The portions of the welding process grooves 43 facing each other are welded together so that the first and second adjusting rolls 41 and 42 are integrated with each other.

Each of the first and second adjustment rolls 41 and 42 is shrink-fitted to the outer periphery (more specifically, the outer periphery of the projection 11) of the iron core roll 10, (Or entire) of the first and second adjusting rolls 41 and 42 which are held in contact with the outer circumferential edge of the protruding portion 11 by heating the protruding portion 11, Of the iron core roll 10 in which the first and second adjusting rolls 41 and 42 are correspondingly fitted and the protruding portions 11 to be fitted are formed, Or the entire iron core roll 10 is heated. (Cooling or the like) of the first and second control rolls 41 and 42 and the portion of the protruding portion 11 in which the first and second control rolls 41 and 42 are fitted between the iron core rolls 10 They have a coupling structure that never fails to mutually exist.

Due to the engagement of the first and second adjustment rolls 41 and 42, the first adjustment roll 41 is separated from the iron core roll 10 by the remaining length in the longitudinal direction excluding the one end coupled with the protrusion 11, The second adjusting roll 42 is spaced apart from the outer circumferential edge of the iron core 10 in the longitudinal direction except for one end of the second adjusting roll 42 which is engaged with the protrusion 11, Thereby forming an empty space called a space 30.

When the tension adjusting space 30 is formed at both ends of the roller as described above, a plurality of such rollers are arranged so as to correspond to each other, and then the two ends of the roller (the first and second rollers) When the pressing force P is applied to the first and second adjusting rolls 41 and 42 and the pressing force larger than the predetermined pressure is applied to the first and second adjusting rolls 41 and 42, Each of the first and second elastic members 41 and 42 is bent into the tension adjusting space 30 (the size of the tension adjusting space 30 is reduced) and absorbs a part of the pressing force. Even when a plurality of tension control rolls 100 used in the atmosphere according to the present invention are closely contacted with each other to apply a uniform pressing force so that both ends of the rollers are struck and not bent, The adhesive surface is kept horizontal and the problem of damaging the film F to be transferred is prevented . That is, as the pressing force applied to both ends of the outer circumference of the first and second adjusting rolls 41 and 42 is relatively larger than the predetermined pressure, the first and second adjusting rolls 41 and 42 are bent into the tension adjusting space 30 Of course,

In addition, when a roll of an elastic material is further provided inside both ends of the roller, it is necessary to change the roll of the elastic material having the hardness corresponding to the preset pressing force each time, but in the present invention, Since the pressing force is absorbed and adjusted by the inner space size (the distance or width between the first and second adjusting rolls 41 and 42 and the iron core roll 10) It is possible to use it without using it.

The outer roll 50 is a circular tubular body with an empty interior and open at its both ends and is fitted and fixed to the outer circumferences of the first and second control rolls 41 and 42 described above.

The outer roll 50 may be formed in various forms such as rubber, plating, paint coating or the like according to various embodiments of the user so that any one of metal, paint, rubber, silicone, urethane, ceramic and epoxy is used .

The outer cover 60 corresponds to both ends of the iron core roll 10 and is coupled to the tension adjusting space 30 formed between the iron core roll 10 and the first and second adjusting rolls 41, So that external foreign matter does not flow into the inside.

The outer cover 60 is formed in a disc shape so as to simultaneously support the side surfaces of the iron core roll 10, the first and second outer rolls and the outer roll 50 from both sides of the iron core roll 10, The outer cover 60 is fixed to the rotary shaft 20 outside the iron core roll 10 by means of bolts or the like so that the tension adjusting space 30 is sealed so as not to be seen from the outside, The first and second outer rolls are bent into the tension adjusting space 30 and the action of absorbing the pressing force becomes possible since the first and second outer rolls are fixed only by the rotary shaft 20 on both end sides of the iron core roll 10. [

Or the entire spoon tension adjusting space 30 and inserted into the tension adjusting space 30 which are respectively opened at both ends of the iron core roll 10 (For example, by using interference fit, heat shrinkage, or the like).

In addition, the tension control roll 100 used in the air of the present invention can be made of a non-iron material or an iron material.
