The adhesive member 1 is wound on the unwinding roller 5 to be described later, and may be exemplarily a tape, and may be adhered to the above-described protective film (F). Of course, the above-described tape is not limited to the example described, and various members may be used as long as it can be adhered to the above-described protective film (F).

The support part 2 is to support the object M to which the protective film F is attached to one side. Here, one side (one side, etc.) may mean an upper side (upper side, etc.) with reference to FIG. 1, and the other side (the other side, etc.) to be described later may mean a lower side (lower side, etc.) with respect to FIG. 1 . have. The same will be applied in the following description.

The above-described protective film (F) is disposed on one surface of the object (M) and adhered, and the other surface (the surface to which the protective film (F) is not attached) of the object (M) is supported by the support (2). can be The support part 2 will be described in more detail in the following description.

The winding roller 3 is disposed on one side of the support portion 2 and winds the loosened adhesive member 1 .

As described above, it is said that the adhesive member 1 is wound around the unwinding roller 5 , but the apparatus may include the unwinding roller 5 disposed on one side of the support part 2 .

The winding roller 3 may be disposed in front of the unwinding roller 5 when the apparatus is viewed from a side cross-section as shown in FIG. 2 . Here, the front means the right side with reference to FIG. 2, and the rear, which will be described later, means the left side with reference to FIG. 2, and the same will be applied in the following description.

The winding roller (3) is disposed in front of the unwinding roller (5) to wind the adhesive member (1) of the unwinding roller (5) and to release the adhesive member (1) from the unwinding roller (5). do.

The tension roller 4 is disposed on one side of the support part 2 and disposed on the other side of the winding roller 3 .

More specifically, the tension roller 4 is disposed on the other side of each of the winding roller 3 and the unwinding roller 5, and when the apparatus is viewed from a plan view, the tension roller 4 is the winding roller ( 3) and may be disposed between the unwinding roller (5).

Each of the rollers (winding roller 3, unwinding roller 5, tension roller 4, which will be described later, etc.) can rotate about each axis A, and the axes A of the rollers are mutually can be parallel. That is, the winding roller 3 , the unwinding roller 5 , the tension roller 4 , and rollers to be described later may be arranged parallel to each other.

Illustratively, the axis A of the rollers may be arranged parallel to the longitudinal direction (left and right direction with reference to FIG. 1 ) of the rollers.

When the adhesive member 1 released from the unwinding roller 5 is wound around the winding roller 3 again, the tension roller 4 moves the adhesive member 1 to the other side to apply tension.

As described above, the tension roller 4 is said to be disposed on one side of the support part 2, and the object M to which the protective film F is attached is the tension roller 4 and the support part ( 2) moves forward through the space between (see Fig. 3), and the adhesive member 1 passing through the tension roller 4 is attached to the protective film F to protect the object M as it passes forward. The film F is peeled off from the object M (see FIG. 4 ).

The protective film F attached to the adhesive member 1 is wound around the winding roller 3 together with the adhesive member 1 (refer to FIG. 5).

With the above structure, the device has an advantage that the protective film F attached to the object M can be easily peeled off at a faster speed. Therefore, it is possible to shorten the time of the process itself of manufacturing a finished product by using the object M, and there is no need to hire a manpower to remove the protective film F attached to the object M, which makes the finished product more economical. There is an advantage that can be manufactured.

In addition, the protective film (F) is wound on the winding roller (3) together with the adhesive member (1), so the adhesive member (1) wound on the winding roller (3) is removed and the protective film (F) can also be processed together. There is also the advantage of being easy to use.

3 to 5 , the support part 2 may be a roller whose surface is made of a urethane material.

2 to 5, the tension roller 4 rotates in a counterclockwise direction based on FIG. 2, and the roller rotates in a clockwise direction based on FIG. 2, and the tension roller 4 and It is possible to move the protective film (F) and the object (M) supplied between the rollers to the front side.

As such, since the support part 2 is a roller, the friction between the object M and the support part 2 moving from the rear to the front can be minimized to minimize damage to the object M.

As described above, since the surface of the roller is made of a urethane material, the processability, abrasion resistance, oil resistance, and aging resistance may similarly be excellent.

In addition, it was said that the above-mentioned object M may be made of a metal material, and urethane is known to have excellent adhesion to the above-mentioned metal. Therefore, the protective film (F) passes through the space between the tension roller (4) and the support part (2) and is attached to the adhesive member (1) and moves to the winding roller (3) side when the object (M) is a support part whose surface is made of a urethane material. (2) attached to the object (M) and the protective film (F) can be separated more easily.

As such, the present device has the advantage of being able to rotate the other by rotating any one of the winding roller 3 and the tension roller 4 by including the driving means 6 including the first chain 61 . have.

Of course, the shaft A of any one of the winding roller 3 and the tension roller 4 may be rotated by a person or connected to a motor.

1 and 2 , the driving means 6 may include a driving roller 62 disposed on the other side of the support part 2 .

The longitudinal direction of the driving roller 62 may also be parallel to the longitudinal direction of the tension roller 4, and the axis A of the driving roller 62 may also be parallel to the axis A of the tension roller 4 have.

Of course, the driving roller 62 and the shaft A of each of the rollers may also be rotatably connected to the housing 9 .

In addition, the driving means 6 is coupled to the shaft A of each of the support part 2 (roller) and the driving roller 62, and the shaft A of each of the support part 2 and the driving roller 62 is provided. It may include a second chain 63 that rotates on both axes.

Also, the apparatus may include a first fixing lever 7 connected to the winding roller 3 and a second fixing lever 8 connected to the driving roller 62 . Exemplarily, the first fixing lever 7 and the second fixing lever 8 may be connected to the housing 9 to control the rotation of the winding roller 3 and the driving roller 62 , respectively. This is commonly used in the relevant field, and a more detailed description will be omitted.

Hereinafter, a method for removing a protective film (hereinafter referred to as 'this method') according to an embodiment of the present invention will be described. This method is a method of removing the protective film (F) using the above-described device, and since it includes the same or corresponding technical features as the above-described device, the same reference numerals are used for the same or similar configuration as the above salpin configuration, Duplicate descriptions will be simplified or omitted.

1 to 5 , in this method, the object M is moved with the tension roller 4 so that the protective film F attached to the object M comes into contact with the adhesive member 1 . and the step (S1) of supplying between the support parts (2).

The object M and the protective film F attached to the object M are disposed behind the space between the tension roller 4 and the support part 2 (hereinafter, the space between them). At this time, the protective film (F) is arranged on one side of the object (M).

After that, the object M and the protective film F are put into the space between them (see FIG. 3), and the object M is moved forward by the rotation of the tension roller 4, the tension roller ( 4) The adhesive member 1 passing through is adhered to the protective film F so that the protective film F is separated from the object M (see FIG. 4 ).

The adhesive member 1 to which the protective film F is attached is wound around the take-up roller 3 (refer to FIG. 5).

On the other hand, the device may include a waterproofing material (GS) and a functional additive (G) applied to the outer surface of the winding roller (3).

The waterproofing material GS is applied to the outer surface of the winding roller 3 and may contain 5 parts by weight of urethane (compared to 0.2 parts by weight of latex to be described later). The waterproofing material GS includes urethane to add waterproofness to the winding roller 3 .

The functional additive (G) contains 0.2 parts by weight of latex, is fibrous and includes a stretchable sheathing material (G1) dispersedly disposed in the waterproofing material (GS), 0.4 parts by weight of bismuth nickel iron oxide, and has a particle shape, but the stretchable sheathing material Containing 0.2 parts by weight of a mixture of a variable material (G2), magnetite, polyacrylic acid, and polyoxyethylene accommodated in (G1), the stretchable outer material (G1) A cationic material (G3) provided at either end of both side ends, and 0.2 parts by weight of p-styrenesulfonic acid (SSNa), the other of both ends of the stretchable outer material (G1) It includes an anionic polymer material (G4) provided at one end (the ratio of each component of the functional additive (G) was based on 0.2 parts by weight of latex).

Referring to FIG. 6 , when the functional additive G is described in more detail, the stretchable outer material G1 includes latex that is elastically deformable to respond to a volume change of the variable material G2 to be described later.

If the latex of the stretchable outer material (G1) is less than 0.2 parts by weight, there is a risk that the variable material (G2) may be lost because the variable material (G2), which will be described later, is not sufficiently wrapped with a sufficient thickness, and when the latex exceeds 0.2 parts by weight, the functionality Since the weight of the additive (G) is excessively increased and the functional additive (G) moves to the lower side of the waterproofing material (GS) in a mixed state with the waterproofing material (GS), there is a problem that the dispersibility is reduced.

Common materials such as waterproofing materials (GS) generally increase in volume as the temperature increases. However, the volume of bismuth nickel iron oxide (BiNi1-xFexO3) included in the variable material G2 and which is an oxide ceramic material decreases as the temperature increases. Bismuth nickel iron oxide was used because it has more than twice the 'negative thermal expansion' effect of conventional materials (eg, zirconium vanadate, etc.) at room temperature.

[A] of FIG. 6 is a view for explaining the functional additive (G) at a first temperature (for example, 10 ℃) of room temperature. [B] of FIG. 6 is a view for explaining the functional additive (G) at a second temperature (eg 20 °C) higher than the first temperature among room temperature.

In FIG. 6 , when the waterproofing material GS increases from the first temperature to the second temperature, the volume increases. In this case, there is a problem in that the waterproofing material GS is bent and wrinkled. Through this, there is a problem that the applied waterproofing material GS is separated from the winding roller 3 and peeling may occur.

The above-described functional additive (G) is to suppress an increase in the volume (or horizontal direction (left and right direction with reference to FIG. 6)) of the waterproofing material (GS) according to the temperature rise, and the variable material (G2) is the above-described As the temperature increases, the volume decreases as the temperature increases.

It is said that the stretchable outer material G1 is a material that is elastically deformed, and as the volume of the variable material G2 is reduced as shown in [B] of FIG. In this way, by including the variable material (G2) in the functional additive (G), the waterproof material (GS) suppresses the volume change according to the temperature change to suppress the wrinkling, thus effectively suppressing the occurrence of peeling. There are advantages to being able to

The bismuth nickel iron oxide of the variable material G2 is preferably used in an amount of 0.4 parts by weight, but when less than 0.4 parts by weight of the bismuth nickel iron oxide is used, there is a problem that the volume change of the waterproofing material GS cannot be effectively suppressed. When the nickel iron oxide exceeds 0.4 parts by weight, there is a problem in that the dispersibility of the functional additive (G) is reduced by excessively increasing the weight of the functional additive (G).

The variable material G2 (bismuth nickel iron oxide) is preferably in the form of particles, and a plurality of variable materials G2 in the form of particles may be accommodated in the fibrous stretchable outer sheath G1. As described above, since the bismuth nickel iron oxide of the variable material (G2) has a large number of particle shapes, it is possible to change the shape of the fibrous and elastically deformable stretchable outer covering material (G1) because it is free to move, and the present composition (waterproof material (GS) ) and the functional additive (G)) corresponding to the shape of the winding roller 3 to which the functional additive (G) is applied, the shape of the functional additive (G) may also be variously changed. For example, in FIG. 6, the functional additive (G) is ' - Although it has a 'shape, it can be bent and changed into various shapes such as 'ㄱ', 'ㄴ', 'S', etc. That is, it is possible to improve the adhesion between the waterproofing material (GS) and the functional additive (G).

In addition, the shell material (G1) of the functional additive (G) is an elastic material, and as described above, it can add toughness to the waterproof material (GS) including the fibrous latex, so that the waterproof material (GS) is torn or damaged It has the advantage of being able to effectively suppress things.

The cationic material G3 is provided at either end (the right end in FIG. 6) of both ends of the stretchable outer material G1. As described above, magnetite, polyacrylic acid) And polyoxyethylene (polyoxyethylene) was used to add a positive polarity to either side of the functional additive (G).

Magnetite became magnetic when it was subjected to an external magnetic field, but when the external magnetic field is removed, the residual magnetism disappears and there is no side effect due to the residual magnetism. The magnetite may be provided on either end side of the stretchable envelope G1.

Polymethacrylic acid is coated on the surface of the magnetite, and contains a plurality of carboxyl groups to form a coordination bond with the magnetite at multiple bonding points, so coating stability can be improved.

Polyoxyethylene may react with a carboxyl group that does not form a coordination bond with magnetite on the surface of polymethacrylic acid to form a stable bond through an amide bond to impart positive charge properties to the magnetite. The positive surface charge of the cation material G3 may have a surface zeta potential of +30 mV or more.

It is preferable that 0.2 parts by weight of the cationic material (G3) is used. When less than 0.2 parts by weight of the cationic material (G3) is used, the positive charge of the functional additive (G) is not sufficient, and the cationic material (G3) exceeds 0.2 parts by weight. When used, there is a problem of excessively increasing the weight of the functional additive (G).

The anionic polymer material (G4) is provided on the other side of both ends of the stretchable outer material (G1), and may include p-styrenesulfonic acid as described above, in addition to adding a hydrogel pre-polymer may include

The anionic polymer material (G4) may be a mixture of p-styrenesulfonic acid and hydrogel pre-polymer (ratio 1:19) and UV-cured.

It is preferable that 0.2 parts by weight of p-styrenesulfonic acid of the anionic polymer material (G4) is included. When less than 0.2 parts by weight of p-styrenesulfonic acid is used, the negative charge of the functional additive (G) is not sufficient, and p- When the amount of styrenesulfonic acid exceeds 0.2 parts by weight, the weight of the functional additive (G) is excessively increased to reduce dispersibility.

When the waterproofing material (GS) contains a large number of units (GU) of the functional additive (G), the neighboring units (GU) are separated by shear force in a stirring (mixing) situation to improve the dispersibility of each component in the composition. can

As described above, the functional additive (G) is said to contain the anionic polymer material (G4) of the cationic material (G3) at both ends of the stretchable outer material (G1), respectively. After mixing, the waterproofing material (GS) is a winding roller After being applied to (3), neighboring units (GU) can be attached by electrostatic attraction. Toughness may be imparted by electrostatic attraction between the polymer materials G4 .

At this time, the magnetite of the cationic material (G3) is a mineral that is likely to be damaged by impact, and the anionic polymer material (G4) is a polymer material that is basically easier to deform than a mineral. Therefore, when the neighboring units (GU) are mutually attached by electrostatic attraction, the shape of the anionic polymer material (G4) is changed by the cationic material (G3), thus reducing the impact applied to the cationic material (G3) Therefore, it is possible to effectively suppress the damage of the functional additive (G).

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
