Description

The present invention relates to a protective film peeling device for peeling a protective film from a laminate comprising a base material and a protective film attached to at least one surface of the base material.

In order to prevent scratches, corrosion, dirt, etc. from adhering to the surface of the plate during transportation and processing, a protective film is often attached to the surface of the plate. Conventionally, it is necessary to peel off the protective film at the time of use or reuse of the plate material having such a structure, and various peeling methods are used.

For example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2002-46935), "In a sticking member peeling device for peeling a sticking member to which an adhesive material is attached from a sticking member, a first rotating member and the first rotating member are described. A second rotating member that rotates in the opposite direction to the first rotating member and a driving means for rotating the first rotating member are provided adjacent to the first rotating member, and are attached by rotation of the first rotating member. The attachment is characterized in that the end portion of the attachment member is turned up, the attachment member is sandwiched between the first rotating member and the second rotating member, and the attachment member is peeled off from the attachment member. A member peeling device. ”Is disclosed.

Further, Patent Document 2 (Japanese Unexamined Patent Publication No. 2003-252526) states that "a work to which a protective film is attached and a rotating rotating rubber roller are provided, and the work is moved by moving the work, the rotating rubber roller, or both. The protective film peeling method is characterized in that the edge portion protective film of the above is brought into contact with the rotating rubber roller so as to face each other to create a trigger for peeling the protective film from the work. ”

Furthermore, Patent Document 3 (Japanese Unexamined Patent Publication No. 2013-159094) states, "While running a film provided with a film on at least one side of a melt-extruded base film, hair made of metal fiber is applied to the film. When the rotating brush having the above is brought into contact with the film to remove the coating film, the holding angle between the rotating brush and the base film shall be 20 ° or more, and the surface speed of the rotating brush shall be 10 to 300 times the traveling film speed. A method for removing a film surface coating, which is characterized by the above. "

However, in the sticking member peeling device of Patent Document 1, when the sticking member is a soft film, the sticking member causes wrinkles, sagging, etc. due to the pressing of the first rotating member, which is entangled with the rotating member to rotate. There is a risk of stopping. Further, when the sticking member is not continuously stuck on the sticking member, it is inefficient because the end portion needs to be sandwiched between the rotating members every time the sticking member is switched.

Further, the protective film peeling method of Patent Document 2 and the film surface coating removing method of Patent Document 3 require a fixing mechanism for bringing the work into close contact with the rotating mechanism for peeling, which complicates the structure of the device to be used. In addition, it is inefficient because the protective films on the front and back cannot be peeled off at the same time.

Focusing on the structure of the conventional protective film peeling device, the work fixing mechanism, the conveying mechanism, and the carrying-out mechanism cannot be widely used for various protective films. Also, regarding the peeling mechanism, not only can the protective film on one side be peeled off in a single process, but there is still room for improvement in many respects, such as the need for a separate pressing mechanism to position the workpiece during peeling. It was.

Therefore, the present invention has been made in view of the above problems, and the protective films on the front and back surfaces can be reliably peeled off by a single treatment, and various protective films can be applied, so that the number of parts can be reduced. It is an object of the present invention to provide a protective film peeling device having a simplified structure.

In order to solve the above problems, the present invention

In the protective film peeling device of the present invention having such a configuration, a pair of rotating brushes provided on the peeling portion are substantially formed on the front and back surfaces of the laminate, corresponding to a base material having a wide thickness such as a soft and continuous thin film. Even if the laminate is configured by abutting at the same timing and the protective films are attached to both sides of the base material, both protective films can be peeled off at the same time in one treatment, which greatly reduces the treatment time. Can be highly efficient. In addition, even if there is no separate pressing mechanism, the laminated body will not be caught between a pair of rotating brushes, transport rollers, and carry-out rollers (in other words, "pinched") and will not warp up and down during peeling, so the protective film will wrinkle. Is not generated, and entanglement or the like that hinders the operation of the rotating brush can be suitably prevented.

Further, in the above-mentioned protective film peeling device of the present invention,
A force is applied by the pair of rotating brushes, the pair of transport rollers, and the pair of unloading rollers in the direction of the laminate or the base material.
It is desirable that the pressing force applied by the pair of rotating brushes is equal to or greater than the pressing force applied by the pair of transport rollers and the pair of carry-out rollers.

In the protective film peeling device of the present invention having such a configuration, a laminate composed of a synthetic resin base material and a protective film is conveyed and carried out by a transfer roller and a carry-out roller that can be appropriately sandwiched, and a rotating brush is used. It can be locked to the protective film and surely peeled off.

Further, in the above-mentioned protective film peeling device of the present invention,
The pair of rotating brushes can adjust the distance between the rotating axes according to the thickness of the laminated body.
It is desirable that the pair of transport rollers and the pair of unload rollers sandwich the laminate and the base material at a constant pressure, respectively.

In the protective film peeling device of the present invention having such a configuration, the rotating brush can be appropriately brought into contact with the protective film and peeled. Further, the laminated body can be reliably sandwiched and carried out at a constant pressure from the start to the completion of peeling.

Further, in the above-mentioned protective film peeling device of the present invention,
It is desirable that the horizontal distance between the rotating brush and the rotating shafts of the conveying roller and the unloading roller is 100 mm to 350 mm.

In the protective film peeling device of the present invention having such a configuration, the optimum distance between the contact position between the pair of transport rollers and the carry-out roller and the laminate and the contact position between the pair of rotating brushes and the laminate. Even a short laminated body can be reliably processed. Further, while suppressing the bending of the laminated body between the transporting portion and the carrying-out portion and the peeling portion, the laminated body having a length of 300 mm or more can be reliably conveyed to the peeling portion and carried out from the peeling portion to the carrying-out portion.

However, the present invention is not limited to those shown in the drawings, and each drawing is for conceptually explaining the present invention. Therefore, the dimensions, ratios or numbers are exaggerated as necessary for easy understanding. Alternatively, it may be abbreviated. Further, in the following description, the same or corresponding parts may be designated by the same reference numerals, and duplicate description may be omitted.

1. 1. Outline of Protective Film Peeling Device 1 An outline of the protective film peeling device 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a schematic view showing an outline of the protective film peeling device 1 according to the present embodiment. In this embodiment, for easy understanding, the width direction of the protective film peeling device 1 is defined as X, the depth direction of the protective film peeling device 1 is Y, and the height direction of the protective film peeling device 1 is Z. To do. Further, the transport direction of the laminated body 51 is X1, and the reverse direction is X2.

As shown in FIG. 1, the protective film peeling device 1 is a device that peels the protective film 51B from the laminate 51 composed of the base material 51A and the protective film 51B attached to the surface of the base material 51A. is there. Further, even in the laminated body 51 formed by attaching the protective films 51B to both the front and back surfaces of the base material 51A, both protective films 51B can be peeled off at the same time in one treatment, so that the peeling treatment becomes highly efficient. It enables a significant reduction in processing time.

Here, the base material 51A is a substantially plate-like member formed of a synthetic resin as a material, and the protective film 51B is a thin film formed of a synthetic resin as a material. The protective film peeling device 1 of the present embodiment can be used for various laminated bodies 51 configured by attaching the protective film 51B to a part or the entire surface of the front surface and / or the back surface of the base material 51A. In particular, when the base material 51A having a length of 300 mm or more, a width of 50 to 500 mm, and a thickness of 1.5 to 15 mm is used, the present inventors use the protective film peeling device 1 of the present embodiment to further remove the protective film. It has been experimentally confirmed that it can be peeled off reliably.

2. 2. Structure of Protective Film Peeling Device 1 The protective film peeling device 1 according to the present embodiment includes a pair of rotating brushes 9 having a parallel rotation axis and sandwiching the laminated body 51, and a peeling portion for peeling the protective film 51B from the laminated body 51. 3 and a pair of transport rollers 11 for sandwiching and transporting the laminated body 51 with the rotating shaft parallel to each other, and the transporting portion 5 for transporting the laminated body 51 to the peeling portion 3 and the rotating shaft parallel to each other to sandwich and transport the laminated body 51. A unloading section 7 having a pair of unloading rollers 13 for unloading and carrying out the base material 51A after peeling the protective film 51 from the peeling section 3 and a suction section 15 for sucking and removing the protective film 51B peeled off by the peeling section 3 are provided. Equipped. Then, the suction portion 15 is located between the peeling portion 3 and the transport portion 5, and while rotating so that the brush tip portion of the rotary brush 9 abuts in the direction X2 opposite to the transport direction X1 of the laminated body 51 The protective film 51B of the laminated body 51 comes into contact with the surface to which the protective film 51B is attached.

<Peeling part 3>
The structure of the peeling portion 3 will be described in detail with reference to FIGS. 2 and 3. 2A and 2B are views showing the structure of the rotating brush 9, FIG. 2A is a side view of the rotating brush 9, and FIG. 2B is a cross section of arrowhead A in FIG. 2A. It is a figure. FIG. 3 is a schematic view showing the structure of the peeling portion 3.

The peeling portion 3 is a portion configured to sandwich the laminated body 51 between the two rotating brushes 9. Specifically, the rotary brush 9 is composed of a substantially cylindrical core material 17 made of various metals and a large number of protrusions 19 arranged on the surface of the core material 17. The diameter of the core material 17 is preferably set in the range of 50φ to 200φ, preferably in the range of 80φ to 180φ, and more preferably in the range of 100φ to 110φ. Further, the axial dimension may be appropriately determined according to the size of the laminated body 51 to be processed.

The protrusion 19 is a channel brush having sufficient rigidity to peel off the protective film 51B from the laminated body 51, and can be made of, for example, a metal having a predetermined corrosion resistance such as brass or stainless steel, a resin having rigidity, or the like. The rotary brush 9 is a channel brush roll formed by winding a base material having protrusions 19 around a core material 17, and the protrusions 19 are oriented outward from the surface of the core material 17 (direction substantially perpendicular to the tangential direction of the surface). It is arranged radially. The wire diameter of the protrusion 19 may be appropriately determined according to the configuration of the laminated body 51 to be used and the thickness dimension of the protective film 51B, but is 0 in order to ensure the strength and surely scratch and peel off the protective film 51B. It is desirable to set it in the range of .08φ to 1.0φ.

Further, if the density of the protrusions 19 with respect to the surface of the core material 17 is low, the number of protrusions 17 that scratch the protective film 51B is insufficient, and if it is high, each protrusion 19 cannot be bent and the scratching force applied to the protective film 51B is hindered and peeled off. It is desirable to wrap a channel brush having a width of 2.5 mm to 5.5 mm and a height of 2.5 mm to 5.5 mm around the surface of the core material 17 because the capacity is reduced. Specifically, the number of preferable protrusions 19 on the surface of the core material 17 is preferably 6 to 2000 for 10 mm ² .

Two rotating brushes 9 having the above configuration are prepared, and one rotating brush 9 is moved downward and the other so that both rotation axes are parallel to the depth direction Y and substantially straight with respect to the height direction Z. The peeling portion 3 is formed by arranging the rotating brush 9 upward. The distance W1 between the rotating shafts of both rotating brushes 9 is automatically adjusted in conjunction with the sensor unit 25 and the conveying unit 5, which will be described later, so that both rotating brushes 9 can be moved according to the thickness dimension of the laminated material 51 used. It is desirable that the separation distance W2 between the provided protrusions 19 is appropriately adjustable (see particularly FIG. 3). Although the present embodiment describes a mode in which the separation distance W2 between the protrusions 19 is adjusted by operating both the one and the other rotating brush 9 up and down, the one or the other rotating brush 9 is described as a representative. It is also possible to operate only one of them. Further, both rotating brushes 9 are rotated in conjunction with each other by being separately connected to a mechanism (not shown) such as a motor.

<Transporting unit 5 and unloading unit 7>
Next, the structures of the transport unit 5 and the carry-out unit 7 will be described in detail with reference to FIGS. 4 and 5. 4A and 4B are views showing the structures of the transport roller 11 and the unloading roller 13, FIG. 4A is a side view of the transport roller 11 and the unloading roller 13, and FIG. 4B is FIG. 4 (b). It is sectional drawing of arrow B in a). Further, FIG. 5 is a schematic view showing the structures of the transport unit 5 and the carry-out unit 7.

The transport unit 5 is a portion in which the laminated body 51 is sandwiched between the two transport rollers 11 and is transported to the peeling portion 3 by rotating the transport roller 11. Further, the carry-out portion 7 is a portion where the base material 51A is sandwiched between the two carry-out rollers 13 and the base material 51A is carried out from the peeling portion 3 by rotating the carry-out roller 13. The transport unit 5 and the carry-out unit 7 have different roles depending on their relative positions with the peeling unit 3, and have substantially the same structure.

As the transfer roller 11 (delivery roller 13), those having various structures can be used as long as the effects of the present invention are not impaired. For example, a core material 21 made of metal and a surface material 23 made of resin are provided. A transport roller can be used. The core material 21 is a substantially cylindrical part, and the surface material 23 is a part that covers the surface of the core material 21. The axial dimensions of the transport roller 11 (delivery roller 13) may be appropriately determined according to the size of the laminated body 51 to be processed and the size of the rotating brush 9. Further, the diameter of the core material 21 may be determined within a range in which the rigidity of the transport roller 11 (delivery roller 13) can be guaranteed, and the thickness dimension of the surface material 23 may be determined in consideration of aging deterioration and wear due to continuous use. It is desirable to determine the horizontal distance W5 between the rotating axes, which will be described later (see FIG. 7).

Two transfer rollers 11 (delivery rollers 13) having the above configuration are prepared, and one of the transfer rollers 11 is parallel to the depth direction Y while being substantially linear with respect to the height direction Z. The transport unit 5 (unloading unit 7) is configured by arranging the (unloading roller 13) downward and the other transport roller 11 (unloading roller 13) upward. The distance W3 between the rotating shafts of both transport rollers 11 (delivery rollers 13) is automatically adjusted in conjunction with the sensor unit 25 described later, thereby adjusting to the thickness dimension of the laminated material 51 (base material 51A) to be used. It is desirable that the separation distance W4 between the surfaces of both transport rollers 11 (delivery rollers 13) can be appropriately adjusted accordingly (particularly see FIG. 5). In this embodiment, the mode in which the distance W3 between the rotation axes of the transport roller 11 (delivery roller 13) is adjusted by operating both the one and the other transport roller 11 (unload roller 13) up and down is described. However, only one of the one or the other transport roller 11 (delivery roller 13) may be operated. Further, both transport rollers 11 (delivery rollers 13) may be rotated in conjunction with each other by being separately connected to a mechanism (not shown) such as a motor.

Further, it is desirable that the transporting portion 5 (carrying out portion 7) has a structure in which a laminated body 51 (base material 51A after peeling the protective film 51B) is sandwiched by applying a constant pressure. The pressure to be applied may be appropriately adjusted so that the laminated body 51 can be conveyed and carried out while being fixed at the vertical position, and is preferably in the range of 200 N to 1000 N, for example. By adopting such a structure, the laminated body 51 (base material 51A) can be securely sandwiched and fixed from the start to the completion of peeling, and appropriate transport and carry-out can be performed until the peeling process is completed.

In the present embodiment, the present invention is described as represented by the minimum necessary configuration in which only the transport portion 5 and the carry-out portion 7 are arranged before and after the peeling portion 3, but the laminated body 51 is transported or carried out. Rollers and the like may be added. By changing the above configuration according to the size of the laminated body 51 to be used, the protective film 51B can be peeled off more reliably.

<Suction unit 15>
Subsequently, the structure of the suction unit 15 will be described in detail with reference to FIG. 6A and 6B are views showing the structure of the suction unit 15, FIG. 6A is a side view of the suction unit 15, and FIG. 6B is a cross section of the arrow C in FIG. 6B. It is a figure. As shown in FIGS. 6A and 6B, the suction unit 15 used in the present embodiment includes a nozzle unit 27, a pipe unit 29, and a suction device (not shown). The specifications of the suction device are not particularly limited as long as it can suck the protective film 51B after peeling together with air, but it is more preferable if the suction device can appropriately control the suction amount by, for example, inverter control.

The nozzle portion 27 is a substantially fan-shaped part, has openings at the front end portion and the rear end portion, and is provided with a suction path 31 inside so as to communicate the openings of both. Further, the nozzle portion 27 is formed so that the thickness becomes thinner toward the tip portion, and the suction force is improved while optimizing the shape of the suction region (see particularly FIG. 6 (b)). ..

The tube portion 29 is a substantially cylindrical component that communicates the opening at the rear end of the nozzle portion 27 with the suction machine. The material is not particularly limited as long as it has rigidity that can withstand the internal negative pressure generated during suction. Further, in order to make the arrangement and handling easier, a bellows structure may be adopted. The diameter of the tube portion 29 is preferably in the range of 150 mm to 200 mm in order to prevent the protective film 51B after peeling from being clogged inside.

<Arrangement of each part>
Next, the arrangement of the above-mentioned parts will be described in detail with reference to FIG. 7. FIG. 7 is a schematic view showing the arrangement of each part constituting the protective film peeling device 1 according to the present embodiment. As shown in FIG. 7, in the direction X, the transport portion 5 is arranged on the left side of the peeling portion 3, the carry-out portion 7 is arranged on the right side of the peeling portion 3, and the suction portion 15 is placed between the peeling portion 3 and the transport portion 5. It is desirable to configure the protective film peeling device 1 by arranging the first sensor unit 25A on the left side of the transport unit 5 and arranging the second sensor unit 25B on the right side of the carry-out unit 7.

The first sensor unit 25A and the second sensor unit 25B are, for example, composed of an electronic element type photodetector or the like, and are components that detect the presence or absence or movement of a detection target within a predetermined range. Specifically, an infrared sensor or the like can be used, but it can be widely used as long as it can detect the laminated body 51 and the base material 51A after peeling the protective film 51B. Further, if the sensor can detect the thickness of the laminated body 51 and the thickness of the base material 51A after the protective film 51B is peeled off, it is possible to more easily and surely adjust the separation distance W4 between the transport portion 5 and the carry-out portion 7. (Depending on the configuration, it is also possible to adjust the separation distance W2 of the peeling portion 3). The first sensor unit 25A is in charge of controlling the transport unit 5 (including the peeling unit 3 depending on the configuration), and the second sensor unit 25B is in charge of controlling the carry-out unit 7.

In the present embodiment, the first sensor unit 25A detects the laminated body 51 to start the operation of the transport unit 5, and the second sensor unit 25B detects the base material 51A after the protective film 51B is peeled off to start the operation of the transport unit 5. It is configured to start the operation of 7. The peeling unit 3 may start the operation when the first sensor unit 25A detects the laminated body 51, or may start the operation in conjunction with the operation of the transport unit 5.

The rotary brush 9, the transfer roller 11, and the unload roller 13 are arranged so as to be movable in the direction Z, respectively, and the above-mentioned distance between the rotation axes W1 (W3) and the separation distance W2 (W4) can be changed by this movement. It can be adjusted accordingly. The movable width W6 of each of the rotating brush 9, the transport roller 11, and the unload roller 13 is preferably 50 mm to 150 mm with respect to the direction Z. By setting the movable width W6 within the above range, it is possible to reliably peel off the protective film 51B corresponding to the laminated body 51 having a wide thickness dimension.

The horizontal distance W5 between the rotating brush 9 and the rotating shafts of the conveying roller 11 and the unloading roller 13 depends on the size of the laminated body 51 to be peeled off and the like, but is preferably in the range of 100 mm to 350 mm. By adopting such an aspect, the distance between the contact position between the pair of transport rollers 11 and the laminate 51 and the contact position between the pair of rotating brushes 9 and the laminate 51 during use is optimized. Even a short laminated body 51 can be reliably processed. Further, while suppressing the bending of the laminated body 51 between the conveying portion 5 and the peeling portion 3, the laminated body 51 having a length of 300 mm or more can be reliably conveyed to the peeling portion 3. The same is substantially the same as above between the peeling portion 3 and the carrying-out portion 7.

The shorter the horizontal distance W5 between the rotating shafts, the shorter the laminated body 51 can be processed. However, if the horizontal distance W5 between the rotating shafts is shortened by a certain amount or more, the rotating brush 9, the transport roller 11, and the carry-out roller can be processed. Since it is necessary to reduce the diameter of the 13 as well, the pressing area against the laminated body 51 and the base material 51A becomes small, the force of scratching the laminated body 51 by the rotating brush 9, and the laminated body 51 by the transport roller 11 and the unload roller 13. In addition, the force for pressing the base material 51A may decrease and may stay inside the apparatus. Therefore, it is desirable to appropriately adjust the dimensional relationship between the horizontal distance W5 between the rotating shafts and the diameters of the rotating brush 9, the transport roller 11, and the unload roller 13 from the above range according to the laminated body 51 to be processed.

The suction portion 15 is positioned between the peeling portion 3 and the transport portion 5 in the direction X, and the tip portion of the nozzle portion 27 is arranged so as to face between the two rotating brushes 9. In order to more preferably suck the protective film 51B, the separation distance between the suction portion 15 and the peeling portion 3 can be appropriately adjusted according to the specifications of the suction device (not shown) and the protective film 51B to be peeled off. desirable.

It is desirable that the rotary brush 9 is rotated in the direction X2 opposite to the direction X1 for transporting the laminated body 51. More specifically, by rotating the transport roller 11 and the unloading roller 13 arranged above in FIG. 7 counterclockwise and the transport roller 11 and the unloading roller 13 arranged below clockwise, the transport unit 5 And the carry-out portion 7 is configured to convey the laminated body 51 in the direction X1, and the rotating brush 9 arranged above is rotated clockwise, and the rotating brush 9 arranged below is rotated counterclockwise to cause the peeling portion. In step 3, the protective film 51B is configured to be peeled off in the direction X2. As a result, the rotating brush 9 can be locked to the protective film 51B and peeled off while conveying the laminated body 51.

3. 3. Method of peeling the protective film 51B using the protective film peeling device 1 Next, a method of peeling the protective film 51B using the protective film peeling device 1 will be described in detail with reference to FIGS. 8 and 9. 8 (a), (b) and (c) are views showing a method of peeling the protective film 51B using the protective film peeling device 1 according to the present embodiment, and FIG. 8 (a) shows the transport unit 5. FIG. 8B is a schematic view of a state in which the laminated body 51 is inserted, FIG. 8B is a schematic view of a state in which the base material 51A reaches the second sensor unit 25B, and FIG. 8C is a schematic view of the base material 51A. It is a schematic diagram which shows the state which is carried out by the carry-out part 7. Further, FIG. 9 is a schematic view showing a mode in which the protective film 51B is peeled from the laminated body 51 by the peeling portion 3.

As shown in FIG. 8A, first, the laminated body 51 is pushed in the direction X1 and inserted into the transport unit 5. The first sensor unit 25A detects the laminated body 51 and rotates the pair of transport rollers 11 in a predetermined direction while gradually reducing the distance W3 between the rotation axes. When the separation distance W4 of the pair of transport rollers 11 is reduced to the thickness dimension of the laminated body 51, the transport portion 5 is in a state of sandwiching the laminated body 51, and the rotation of the pair of transport rollers 11 while applying a predetermined pressure The laminated body 51 is conveyed in the direction X1.

The pair of rotating brushes 9 constituting the peeling portion 3 are interlocked with each other according to the state of the pair of transport rollers 11 that have undergone the above operation, and rotate in a predetermined direction while adjusting the distance between the rotating shafts W1 and the separation distance W2. The laminated body 51 conveyed by the conveying portion 5 reaches the peeling portion 3 and is inserted between the pair of rotating brushes 9.

The protrusions 19 of the upper and lower rotating brushes 9 abut and lock the protective films 51B on the front and back surfaces of the laminated body 51 at the same timing, and the protective film 51B is pulled up and down in the direction X2 by its own rotation and the transfer of the transfer unit 5. Peel off (see FIG. 9). Therefore, since the laminated body 51A is continuously conveyed to the peeling portion 3 by the conveying portion 5, the peeling of the protective film 51B is completed when the edge of the laminated body 51 on the direction X2 side passes through the peeling portion 3. become.

As shown in FIG. 8B, the edge of the protective film 51B peeled off by the peeling portion 3 in the direction X1 is moved between the peeling portion 3 and the conveying portion 5 by the rotating brush 9 and is sucked by the suction portion 15. To. Further, when the peeling of the protective film 51B by the peeling portion 3 is completed by a certain amount, the edge of the base material 51A on the direction X1 side passes through the carrying-out portion 7, and the second sensor portion 25B detects this.

The second sensor unit 25B, which has detected the base material 51A, gradually reduces the distance W3 between the rotation axes while rotating the pair of unloading rollers 13 in a predetermined direction. When the separation distance W4 of the pair of unloading rollers 13 is reduced to the thickness dimension of the base material 51A, the unloading portion 7 is in a state of sandwiching the base material 51A, and the rotation of the pair of unloading rollers 13 while applying a predetermined pressure The base material 51A is conveyed in the direction X1. As a result, the laminated body 51 (partly the base material 51A) is sandwiched between the transport portion 5 and the carry-out portion 7, and is conveyed and carried out in the direction X1 by the rotation of both portions.

As shown in FIG. 8C, even if the edge of the laminated body 51 on the direction X2 side completely passes through the transport portion 5, the carry-out portion 7 continues to move the base material 51A to the direction X1 side. Since it is carried out, the laminated body 51 can appropriately pass through the peeling portion 3 until the peeling of the protective film 51B is completely completed.

The protective film 51B after peeling is sucked by the suction part 15 according to the peeling of the peeling part 3, and is transported to a predetermined place. The place to be transported can be arbitrarily determined by the configuration of the suction unit 15, but if the protective film 51B is configured to be easily processed, the entire work can be made more efficient. When the base material 51A completely passes through the carry-out portion 7, peeling of the protective film 51B using the protective film peeling device 1 according to the present embodiment is completed.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to these embodiments, and the present invention is not limited to these embodiments, and is not deviated from the spirit and teaching of the claims. There are improved and modified examples of. It is easily understood by those skilled in the art that all such improvements and modifications are included in the technical scope of the present invention.
