Description

  The present invention relates to a peeling device that separates a strip-shaped laminate composed of a plurality of layers into two-layer members, and a laminating device to which the stripping device is applied, and in particular, optimum peeling that has excellent peeling stability and hardly causes peeling failure. It is suitable for finding the angle, and prevents peeling failure such as transfer of the center layer such as pressure-sensitive adhesive and interlaminar fracture, and is provided with a release material on both sides of the pressure-sensitive adhesive layer not including the core material. Suitable for peeling of release material from double-sided adhesive tape.

  FIG. 7 is a cross-sectional view of the laminate. The laminated body T in the figure has a three-layer structure in which the peeling members V1 and V2 are temporarily attached to both surfaces of the center layer U, and the peeling forces of the peeling members V1 and V2 are different. In the following description, it is assumed that one peeling member V1 has a weaker peeling force than the other peeling member V2. In the case of this configuration, the central layer U of the laminate T remains on the side of the peeling member V2 having a strong peeling force. That is, when the peeling member V1 having a weak peeling force is peeled from the laminate T, the laminated body T is separated into a peeling member V1, a peeling member V2 having a strong peeling force, and a laminated member W composed of the center layer U. The In addition, a peeling member means the member which can peel continuously from laminated bodies, such as peeling materials, such as peeling paper and a peeling film, and a protective film.

  When peeling the peeling member V1 having a weak peeling force from the laminate T, it is necessary to select a peeling angle at which the peeling can be performed without causing a peeling failure such as transfer of the central layer U or interlayer breakdown. However, since the optimum peeling angle varies depending on conditions such as the material of each layer of the laminate and the peeling speed, it is necessary to find the optimum peeling angle for each condition.

  As a method of peeling the peeling member V1 having a weak peeling force from the laminate T shown in FIG. 7, for example, a method using a wedge-shaped member (22) disclosed in Patent Document 1 can be adopted. When the peeling member V1 having a weak peeling force is peeled by this method, the peeling member V1 having a low peeling force may be bent by the wedge-shaped member (22).

  However, according to the peeling method using the wedge-shaped member (22), nothing is supported on the side of the peeling member V2 having a strong peeling force in the vicinity of the wedge-shaped member (22). For this reason, the peeling member V1 having a weak peeling force tends to shake the laminated member W side little by little, and the vibration causes the stability of peeling of the peeling member V1 having a weak peeling force to be impaired, and an optimum peeling angle at which peeling failure is unlikely to occur. Is difficult to find accurately, and there is a problem in that peeling failure such as delamination of the center layer U easily occurs.

<Outline of peeling device>
The peeling apparatus M1 in FIG. 1 is configured by separating a pair of nip rolls 1A and 1B transporting forward while sandwiching the laminated body T in FIG. 7 and a laminated body T fed from the nip rolls 1A and 1B into two layers of members (with peeling force). The two guide rollers 2A and 2B that guide in different directions as the weak peeling member V1 and the laminated member W), and the guide roller 2A so that the peeling angles θ and α of the peeling member V1 and the laminated member W can be arbitrarily changed. The first variable means 3 that can move the installation position of 2B, and a second variable unit that arbitrarily changes the peeling angles θ and α of the peeling member V1 and the laminated member W by changing the diameters of the nip rolls 1A and 1B. Variable means 4, and third variable means 5 for arbitrarily changing the peel angles θ, α of the peeling member V1 and the laminated member W by changing the distance from the nip rolls 1A, 1B to the guide rollers 2A, 2B; The Eteiru.

<A pair of nip rolls 1A, 1B>
The pair of nip rolls 1A and 1B are arranged vertically so that their outer peripheral surfaces are opposed to each other, and are configured to be able to rotate around their roll axes. Of these nip rolls 1A and 1B, the upper nip roll 1A is made of a rubber roll and can be moved in the vertical direction by a lifting means (not shown). Further, the lower nip roll 1B is made of a metal roll, and is positioned at a fixed position in FIG. 1 by rotatably supporting the roll axis by left and right frames F (see FIG. 2).

  In the peeling apparatus M1, the upper nip roll 1A descends from the standby position indicated by the two-dot broken line in FIG. 1 and comes into contact with the lower nip roll 1B with a predetermined pressure, thereby passing the nip rolls 1A and 1B through. The body T is sandwiched between the pair of nip rolls 1A and 1B, but is not limited to this example. For sandwiching the laminate T between the pair of nip rolls 1A and 1B, both the nip rolls 1A and 1B may be brought closer to each other, or the lower nip roll 1B may be brought closer to the upper nip roll 1A. Moreover, 1A may be a metal roll and 1B may be a rubber roll.

<Two guide rollers 2A, 2B>
The two guide rollers 2A and 2B are located downstream in the transport direction of the stacked body T fed from the nip rolls 1A and 1B. Similarly to the nip rolls 1A and 1B, these guide rollers 2A and 2B are also arranged vertically so that their outer peripheral surfaces face each other, and are configured to be able to rotate around their respective roller axes. It is.

  In the peeling device M1, among the peeling member V1 and the laminated member W of the laminate T fed from the nip rolls 1A and 1B, the peeling member V1 having a weak peeling force is hung on the upper guide roller 2A and guided upward. When the laminated member W is hung on the lower guide roller 2B and guided downward, both the members V1 and W are separated from the vicinity of the contact point between the laminated body T and the nip rolls 1A and 1B, and the peeling member V1 having a weak peeling force is laminated. It is configured to peel from the center layer U of the body T.

<First variable means 3>
The first variable means 3 includes moving means 30 for independently moving the pair of guide rollers 2A and 2B described above, and by changing the moving positions of the guide rollers 2A and 2B individually. The peeling angles θ and α of the members V1 and W can be set separately.

  3 shows that the upper guide roller 2A shown in FIG. 1 is moved upward by a predetermined amount, and the two guide rollers 2A and 2B are relatively separated, so that the peel angle θ of the peel member V1 having a weak peel force is θ1. An example in which the angle is changed from θ to θ2 is shown.

  In the example of FIG. 3, since the lower guide roller 2B is not moved from the position shown in FIG. 1, the peeling angle α of the laminated member W is not changed, but the lower guide roller 2B is moved downward. If it moves quantitatively, the peeling angle α of the laminated member W can also be changed independently. If the movement amounts of the two guide rollers 2A and 2B are equal, the change amounts of the peeling angles θ and α of the members V1 and W are equal. This is because the amount of movement of the guide rollers 2A and 2B and the peeling angles θ and α are geometrically proportional.

  As shown in FIG. 2, the moving means 30 includes a pair of support arms 32 that can swing in the vertical direction via a rotating means 31 attached to the frame F of the peeling apparatus M1, and two sets of upper and lower pairs in FIG. And an arm drive system (not shown) such as a motor that independently swings the support arms 32, and the guide rollers 2A and 2B are attached to the tips of the two sets of support arms 32 one by one. ing. In the case of this structure, the guide rollers 2A and 2B are individually moved in the vertical direction by the independent swinging operation of the support arms 32, and the movement positions thereof are individually changed.

  In the moving means 30, the guide rollers 2A and 2B move following the swinging trajectory of the support arm 32 due to the structure thereof, so that the guide rollers 2A and 2B move on the arc, but the guide rollers 2A and 2B. The movement form is not limited thereto. For example, the guide rollers 2A and 2B may be linearly moved in the vertical direction by attaching the guide rollers 2A and 2B to a slider that can move in the vertical direction. Further, the moving means 30 reversely moves the guide rollers 2A and 2B to nearly 180 degrees as shown in FIG. 1, but a smaller angle may be used.

  In FIG. 2, the laminated member W passes over the guide roller 2B. However, the laminated member W may pass under the guide roller 2B in accordance with the movement position of the guide roller 2B. The same applies to the peeling member V1 passing over the guide roller 2A.

<Second variable means 4>
Each of the pair of nip rolls 1A and 1B described above is detachably attached to the frame F, and the second variable means 4 replaces the detachable nip rolls 1A and 1B with another nip roll having a different diameter. By doing so, the peeling angles θ and α of the respective members (the peeling member V1 and the laminated member W) are arbitrarily changed.

  FIG. 4 is an operation explanatory view of the peeling apparatus M1 of FIG. 1 and is a conceptual diagram of the peeling angle before and after changing the diameters of the nip rolls 1A and 1B.

  When the nip rolls 1A and 1B indicated by the solid lines in FIG. 4 are replaced with small-diameter nip rolls (nip rolls 1A and 1B indicated by a one-dot broken line), the peeling angle of each member (the peeling member V1 and the laminated member W) is changed from θ1. The angle can be changed to a large angle such as θ3, α1 to α3. This is because the small-diameter nip roll has a smaller curvature on the outer peripheral surface of the roll, and the members V1 and W can be bent at a steep angle.

  On the other hand, when the nip rolls 1A and 1B shown by solid lines in FIG. 4 are replaced with large-diameter nip rolls (nip rolls 1A and 1B shown by two-dot broken lines), the peeling of each member (peeling member V1 and laminated member W) is performed. The angle can be changed to a small angle such as θ1 to θ2 and α1 to α2. This is because the large-diameter nip roll has a larger curvature, and the members V1 and W can be bent at a gentle angle.

  The positional relationship between the guide rollers 2A and 2B with respect to the nip rolls 1A and 1B greatly affects the setting of the peeling angles α and θ. However, as the peeling angles α and θ are larger, the area in which each member (the peeling member V1 and the laminated member W) contacts the nip rolls 1A and 1B increases, so that the influence of the nip roll diameter on the peeling angle also increases.

<Third variable means 5>
The third variable means 5 includes a slide means 5A comprising a rail 51 directed in the direction of the nip rolls 1A and 1B and a slider 52 slidable along the rail 51 for each of the two sets of support arms 32 described above. 5B, and the guide rollers 2A and 2B are attached to the sliders 52 via attachment plates 53 one by one. By sliding each slider 52 by a predetermined amount, the nip rolls 1A and 1B The distance to the guide rollers 2A and 2B is changed according to the slide amount.

  A plurality of screw holes 54 are formed along the rail 51 at a predetermined pitch near the rail 51, and the mounting plate 53 is screwed and fixed to the support arm 32 using these screw holes 54. The slide positions of the slider 52 and the guide rollers 2A and 2B are fixed.

  FIG. 5 is an operation explanatory view of the peeling device M1 of FIG. 1, and is a conceptual diagram of the peeling angle before and after changing the distance from the nip rolls 1A, 1B to the guide rollers 2A, 2B.

  When the guide rollers 2A and 2B in the position of FIG. 1 are slid to the position of FIG. 5, the peeling angles θ and α of the respective members (the peeling member V1 and the laminated member W) are θ1 to θ4 and α1 to α4. Can be changed to a larger angle. If the guide rollers 2A and 2B are slid in the opposite direction, the peeling angles θ and α of the members V1 and W are reduced. Further, the separation is further stabilized when the slide is performed in such a manner. This is because the distance between the guide rollers 2A and 2B and the nip rolls 1A and 1B is shortened, so that the shake of the members V1 and W between them is suppressed. Thus, both the peeling angle and the state of the member after peeling can be adjusted by the variable means 5.

  The third variable means 5 is not limited to the method using the slide means 5A and 5B described above. Although illustration is omitted, for example, a dovetail groove is formed in the support arm 32 instead of the rail 51, and a protrusion that is slidably fitted in the dovetail groove is integrally provided on the mounting plate 53, so that the nip roll 1A, A configuration in which the guide rollers 2A and 2B are slidable in the direction 1B may be employed.

<Other configurations>
In the peeling apparatus M1 of FIG. 1, monitoring cameras 12A and 12B are provided so that the state of peeling of each member (the peeling member V1 and the laminated member W) can be monitored with an image. One monitoring camera 12A is disposed on the front side of the guide rollers 2A and 2B, and is mainly used to monitor the peeling angles θ and α of the members V1 and W. Another monitoring camera 12B is used for monitoring the state of various parts of the apparatus, including detection of foreign matter adhesion and wrinkle generation on the surface of the central layer U of the laminated member W exposed by peeling. Moreover, in this peeling apparatus M1, in order to prevent the peeling defect by static electricity, the structure which provides the static electricity removal air injection apparatus 13 upstream of the nip rolls 1A and 1B, and injects the ionized air to a laminated body is employ | adopted. In addition, the installation location of the monitoring camera 12 or the static electricity removal air injection apparatus 13 is not limited to the position shown in FIG. 1, The position can be changed suitably as needed.

<Description of operation of entire peeling device M1>
In the peeling apparatus M1, for example, the laminated body T is supplied between the pair of nip rolls 1A and 1B as shown in FIG. 1 by the first unwinding roll 14 in FIG. 6, and the supplied laminated body T is the nip rolls 1A and 1B. Is sent forward.

  At that time, the pair of guide rollers 2A and 2B guide each member (peeling member V1 and laminated member W) of the laminated body T in different directions (vertical direction in FIG. 1), thereby each member of the laminated body T. V1 and W are vertically divided from the vicinity of the contact point between the laminate T and the nip rolls 1A and 1B, and the peeling member V1 having a weak peeling force peels from the center layer U of the laminate T.

  By the way, in this peeling apparatus M1, the peeling angle of each member (peeling member V1, laminated member W) can be freely set by any one of the first to third variable means 3, 4, 5 or a combination thereof. Thus, an optimum peeling angle that can suppress peeling failure such as delamination of the center layer U can be found.

  For example, if the upper guide roller 2A shown in FIG. 1 is moved upward by a predetermined amount as shown in FIG. 3 by the first variable means 3, the peeling angle θ of the peeling member V1 is changed from θ1 to θ2. If the nip roll 1A indicated by the solid line in FIG. 4 is replaced with a small-diameter nip roll (nip roll indicated by a one-dot broken line), the peeling angle θ of the peeling member V1 can be changed from θ1 to θ3 (second variable means). 4). Furthermore, if the guide roller 2A at the position of FIG. 1 is slid to the position of FIG. 5 by the third variable means 5, the peeling angle θ of the peeling member V1 can be changed from θ1 to θ4.

  In the peeling apparatus M1 of the present embodiment, as described above, the members (peeling member V1 and laminated member W) of the laminate T fed from the nip rolls 1A and 1B are moved in different directions by the guide rollers 2A and 2B, respectively. A configuration was adopted in which the peeling member V1 having a weak peeling force peels by being guided. According to this configuration, peeling of the peeling member V1 having a weak peeling force starts near the contact point between the laminate T and the nip rolls 1A and 1B, and the laminate T is supported from both sides by the pair of nip rolls 1A and 1B immediately before the peeling. Therefore, the peeling angle of each member V1, W can be changed in many ways by the three variable means 3, 4, 5 having different structures or methods, so that the peeling angle can be changed. The degree of freedom of adjustment is high, and it is suitable for finding an optimal peeling angle at which peeling failure hardly occurs, and peeling failure such as interlaminar fracture of the central agent layer U can be prevented.

  In addition, even when the peeling behavior changes due to changing the peeling speed during peeling, it is possible to easily control the peeling behavior by changing the peeling angle, so it is possible to always maintain a stable peeling state. .

FIG. 6 is a side view of a laminating apparatus to which the peeling apparatus of FIG. 1 is applied.

  The present laminating apparatus M2 in FIG. 6 peels the peeling member V1 having a weak peeling force from the laminate T (see FIG. 7) formed by temporarily attaching the peeling members V1 and V2 to both surfaces of the center layer U, and is exposed by peeling. It is an apparatus for bonding a member S typified by an optical film used for a display or the like to the center layer U.

  The laminating apparatus M2 includes two layers of a first feeding means 6 for feeding the laminated body T shown in FIG. 7, a second feeding means 7 for feeding the member S, and a laminated body T fed by the first feeding means 6. The separation member 8 separated into the members (the separation member V1 having a weak separation force, the laminated member W) and the layer exposed by the separation at the separation unit 8 (the central layer U of the laminate T) are separated as the second member. And a laminating portion 9 for bonding the member S fed from the feeding means 7.

<First feeding means 6>

The fed-out laminated body T is conveyed to the said peeling part 8 by the guide roller G1. At this time, when the original fabric R is wound so that the peeling member V1 having a weak peeling force is positioned outside, the original fabric R is installed on the first unwinding roll 14 so as to pass through the first path Y1. . At this time, the original fabric R rotates in the direction of Z1. On the other hand, when the peeling member V1 having a weak peeling force is wound so as to be positioned inside, the raw fabric R is placed on the unwinding roll 14 so as to pass through the second path Y2. At this time, the original fabric R rotates in the direction of Z2.

<Second feeding means 7>
The second feeding means 7 is configured to feed the member S from the original fabric Q by a second unwinding roll 15 capable of pivotally supporting the original fabric Q of the member S wound in a roll shape. The drawn-out member S is conveyed to the laminating unit 9 by the guide roller G2.

<Peeling part 8>
The peeling part 8 peels the peeling member V1 having a weak peeling force from the laminate T by the peeling device M1 shown in FIG. That is, in this peeling part 8, among the members T1 and W of the laminate T sent out from the nip rolls 1A and 1B, the peeling member V1 having a weak peeling force is guided upward by the upper guide roller 2A, and the laminated member W is guided. Guided downward by the lower guide roller 2B. Thereby, from the vicinity of the contact point between the laminated body T and the nip rolls 1A and 1B, the members V1 and W are separated in the vertical direction, and the peeling member V1 having a weak peeling force peels from the center layer U of the laminated body T. Then, the peeling member V1 having a weak peeling force is wound around the first winding roll 10 via the guide roller G3. On the other hand, the laminated member W is conveyed to the laminating unit 9 via the guide roller G4.

<Laminating part 9>
