Abstract

[Problem] To make it possible to more appropriately peel off a section to be peeled off from a kiss-cut sheet-like member. [Solution] A kiss-cutting roller 30 and a backing roller 40 of a vacuum laminator 1, according to the present invention, cut only a film of a sheet-like member (sheet-like laminate S) obtained by laminating a base material (separator) and a sticking member (film). A peeling suppression unit 50 performs peeling suppression processing for suppressing the peeling off from the separator of a first portion (die-cutting region), which is not to be peeled from the separator, in a film that has been cut by the kiss-cutting roller 30 and the backing roller 40, or in a portion of the film that is to be cut. Laminate rollers 90A, 90B apply a second portion (frame body portion), in the film cut by the kiss-cutting roller 30 and the backing roller 40, peeled from the separator to a workpiece.

Description

Laminator and Laminating Method

[0001] The present invention relates to a laminator and a laminating method.

[0002] Conventionally, a laminator that laminates a resin film or the like on a workpiece such as a substrate has been used. As such a laminator, for example, for a sheet-like member to be processed in which a film and a separator are bonded together, only the film portion is half-cut to peel the film having the target shape from the separator, and the peeled film is attached to the workpiece. A method of performing the processing is known (see Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2019-120778

[0004] However, when the film portion bonded to the separator is half-cut, in the process of peeling the film of the target portion from the separator, the film of the unnecessary portion may also be peeled from the separator together. In such a case, the laminating process of attaching the film to the workpiece cannot be appropriately performed.

[0005] An object of the present invention is to realize a technique capable of more appropriately peeling a portion to be peeled from a half-cut sheet-like member.

[0006] In order to solve the above problems, a laminator according to an embodiment of the present invention includes: half-cutting means for cutting only the attaching member of a sheet-like member in which a base material and an attaching member are laminated; and the attaching member cut by the half-cutting means or a portion of the attaching member to be cut by the half-cutting means. Peeling suppression means for performing a peeling suppression process for suppressing the peeling of a first portion that is not a peeling target from the base material; and laminating means for attaching a second portion peeled from the base material of the attaching member cut by the half-cutting means to a workpiece. It is characterized by comprising.

[0007] According to the present invention, it is possible to realize a technique capable of more appropriately peeling a portion to be peeled from a half-cut sheet-like member.

[0009] Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment] [Overall Configuration] Figure 1 is a schematic diagram showing the overall configuration of the laminator 1 according to the present invention. Figure 2 is a partially enlarged view showing the installation position of the peel suppression unit 50. As shown in Figures 1 and 2, the laminator 1 includes a material supply roller 10, tension adjustment rollers 20A, 20B, a half-cut roller 30, a backup roller 40, a peel suppression unit 50, an unwanted material winding roller 60, a film substrate supply roller 70, a protective film winding roller 80, laminating rollers 90A, 90B, and a control unit 100. Guide rollers and the like are appropriately installed in the laminator 1 to change the transport direction of the sheet-like laminate S or film substrate F being transported.

[0010] Furthermore, the laminator 1 includes a first actuator 11 that rotates the adhesive material supply roller 10, a second actuator 21A that rotates the tension adjustment roller 20A, a third actuator 21B that rotates the tension adjustment roller 20B, a fourth actuator 31 that rotates the half-cut roller 30, a fifth actuator 41 that rotates the backup roller 40, a sixth actuator 51 that drives the pressing member 50A of the peel suppression section 50, a seventh actuator 61 that rotates the unwanted material winding roller 60, an eighth actuator 71 that rotates the film substrate supply roller 70, a ninth actuator 81 that rotates the protective film winding roller 80, a tenth actuator 91A that rotates the laminating roller 90A, and an eleventh actuator 91B that rotates the laminating roller 90B. Although not shown in the diagram here, torque control mechanisms such as powder clutches and reduction mechanisms can be provided between the rotation axis of each actuator and each roller, as needed.

[0011] The adhesive material supply roller 10 winds and accumulates a sheet-like laminate S, which is made up of films (adhesive material) to be attached to a film substrate F (workpiece), around a separator (base material), and delivers the sheet-like laminate S by rotating it with the first actuator 11. The tension adjustment rollers 20A and 20B grip the sheet-like laminate S delivered from the adhesive material supply roller 10 and control the tension applied to the sheet-like laminate S by rotating it while adjusting the transport speed with the second actuator 21A and the third actuator 21B.

[0012] The half-cut roller 30 is equipped with etching blades or engraving blades on its outer circumference and is rotated by the fourth actuator 31 with the sheet-like laminate S sandwiched between it and the backup roller 40, thereby half-cutting the film of the sheet-like laminate S. In this embodiment, the half-cut roller 30 half-cuts the film layers of the sheet-like laminate S so that the frame portion and the individual pieces that are die-cut by the frame portion (hereinafter referred to as the "die-cut area") are continuous.

[0013] Furthermore, by changing the rotational speed of the half-cut roller 30 relative to the backup roller 40, the half-cut shape formed by the half-cut roller 30 on the sheet-like laminate S can be altered.

[0014] Figure 3 is a schematic diagram showing an example of the shape of the cut line of the film formed by the half-cut roller 30. In this embodiment, the outer surface of the half-cut roller 30 has etching blades (or engraving blades, etc.) along the generatrix of the outer surface and etching blades (or engraving blades, etc.) along the circumferential direction of the outer surface. As shown in Figure 3, when the half-cut roller 30 rotates at a lower speed than the speed at which the sheet-like laminate S is conveyed by the backup roller 40, the etching blades (or engraving blades, etc.) along the circumferential direction of the outer surface form a cut line that is longer in the conveying direction. Conversely, when the half-cut roller 30 rotates at a higher speed than the speed at which the sheet-like laminate S is conveyed by the backup roller 40, the etching blades (or engraving blades, etc.) along the circumferential direction of the outer surface form a cut line that is shorter in the conveying direction. Therefore, the half-cut roller 30 can half-cut the die-cut area of ​​the film into multiple types of rectangular shapes with different side lengths in the conveying direction.

[0015] The backup roller 40 is rotated by the fifth actuator 41 while maintaining a set distance between its outer surface and the outer surface of the half-cut roller 30, and conveys the sheet-like laminate S while sandwiching it between the backup roller 40 and the half-cut roller 30. That is, the sheet-like laminate S that is conveyed sandwiched between the backup roller 40 and the half-cut roller 30 is half-cut by the etching blade (or engraving blade, etc.) of the half-cut roller 30. When the sheet-like laminate S is discharged from the backup roller 40, the frame portion of the film is peeled off from the separator and wound onto the laminating roller 90A, while the separator holding the die-cut area is wound onto the waste material winding roller 60.

[0016] The peel-inhibiting unit 50 performs a process (peeling-inhibiting treatment to suppress peeling) on ​​the half-cut sheet-like laminate S to make it difficult for the film (die-cut area) other than the portion to be attached to the film substrate F to peel off from the separator. The peel-inhibiting unit 50 is installed in the transport direction of the sheet-like laminate S between the half-cut process by the half-cut roller 30 and the backup roller 40 and the position where the frame portion of the film is peeled off from the separator. In this embodiment, the peel-inhibiting unit 50 is installed between the time the film is half-cut by the half-cut roller 30 and the time the sheet-like laminate S separates from the backup roller 40. That is, the peel-inhibiting unit 50 performs a process on the sheet-like laminate S, which is in close contact with the outer surface of the backup roller 40, to make it difficult for the film (die-cut area) other than the portion to be attached to the film substrate F to peel off from the separator. Here, the peel-inhibiting unit 50 uses the outer surface of the backup roller 40 as a receiving member and uses the sixth actuator 51 to protrude a pressing member 50A (rod, etc.) to press the film (die-cut area) other than the portion attached to the film substrate F against the separator. This increases the adhesion strength of the die-cut area of ​​the film to the separator, making it difficult to peel the film other than the portion attached to the film substrate F from the separator. Furthermore, it is possible to increase the adhesion strength of the die-cut area of ​​the film to the separator with a simple operation.

[0017] Figure 4 is a schematic diagram showing a processing method to make it difficult for the film other than the portion attached to the film substrate F (die-cut region) to peel off from the separator. In Figure 4, an example is shown in which the peel-suppression unit 50 processes the area near the cutting line (a cutting line in a direction intersecting the transport direction of the sheet-like laminate S) that has been half-cut by an etching blade (or engraving blade, etc.) along the generatrix on the outer surface of the half-cut roller 30 within the die-cut region.

[0018] As shown in Figure 4, by pressing the film against the separator within the die-cut area of ​​the half-cut film, the portion not attached to the film substrate F (the die-cut area) adheres to the separator with stronger adhesion than the portion attached to the film substrate F (the frame portion). Therefore, in the sheet-like laminate S, when the film is peeled from the separator, the frame portion attached to the film substrate F peels off from the separator, while the die-cut area remains adhered to the separator, allowing only the necessary portion to be appropriately peeled from the separator.

[0019] The waste material winding roller 60 is rotated by the seventh actuator 61 and winds up the separator and the waste portion (die-cut area) of the half-cut film. The film substrate supply roller 70 is rotated by the eighth actuator 71 and feeds out the film substrate F to which the frame portion of the half-cut film is attached. The protective film winding roller 80 is rotated by the ninth actuator 81 and winds up the protective film that was attached to the film substrate F while it was being wound onto the film substrate supply roller 70.

[0020] Laminating rollers 90A and 90B press together the frame portion of the film, which has been half-cut by the half-cut roller 30, and the film substrate F supplied from the film substrate supply roller 70, thereby laminating the frame portion of the film to the film substrate F. After the film is attached, the film substrate F' is subjected to appropriate post-processing. In this embodiment, the frame portion of the film in the sheet-like laminate S, which is separated at point P from the outer surface of the backup roller 40, is peeled from the separator and contacts the outer surface of the laminating roller 90A at point Q, and the distance between points P and Q is shorter than a predetermined distance D. That is, the distance over which the frame portion of the film peeled from the separator is carried from the upstream backup roller 40 to the downstream laminating roller 90A is shorter than a predetermined distance D. The predetermined distance D can be set to a distance equal to or shorter than one pitch of the half-cut frame portion (the shortest pitch in the frame portion that has been half-cut into multiple lengths). Therefore, even when the frame portion is peeled from the separator and die-cut in a ladder shape, it is possible to suppress the shrinkage in the width direction due to the tension applied in the transport direction, which can cause wrinkles. However, depending on the characteristics of the sheet-like laminate S, separator, or film (such as resistance to deformation), it is also possible to make the predetermined distance D larger than one pitch of the half-cut frame portion.

[0021] The control unit 100 controls the operation of the first to eleventh actuators 11, 21A, 21B, 31, 41, 51, 61, 71, 81, 91A, and 91B to adjust the transport speed of the sheet-like laminate S, film substrate F, separator, unnecessary parts of the film, and the film substrate F' after the film has been attached in the laminator 1. The control unit 100 also controls the rotation speed of the half-cut roller 30 relative to the backup roller 40 to change the half-cut shape formed by the half-cut roller 30 on the sheet-like laminate S. Specifically, the control unit 100 rotates the half-cut roller 30 at a low speed relative to the speed at which the sheet-like laminate S is transported by the backup roller 40, thereby forming a cut line with a shape that is long in the transport direction by the etching blade (or engraving blade, etc.) along the circumferential direction of the outer surface of the half-cut roller 30. Conversely, the control unit 100 rotates the half-cut roller 30 at a speed relative to the speed at which the sheet-like laminate S is conveyed by the backup roller 40, thereby forming short cutting lines in the conveying direction using etching blades (or engraving blades, etc.) along the circumferential direction of the outer surface of the half-cut roller 30.

[0022] Furthermore, the control unit 100 controls the process in the peel-suppression unit 50 to press the portion of the film other than the portion attached to the film substrate F (the die-cut region) against the separator. Specifically, the control unit 100 controls the operation of the sixth actuator 51 so that the pressing member 50A of the peel-suppression unit 50 presses the film against the separator at a predetermined timing and with a predetermined pressing force. In this embodiment, in the sheet-like laminate S, the film layer is half-cut into a frame portion and a die-cut region, and the die-cut region becomes unnecessary. Therefore, the control unit 100 controls the pressing member 50A to press the film against the separator at the timing when the die-cut region is transported to the installation position of the peel-suppression unit 50. The pressing force used to press the pressing member 50A against the die-cut region can be determined to an appropriate value depending on conditions such as the material of the sheet-like laminate S, the type of adhesive used to bond the film and the separator, and the thickness of the film. The specific pressing force can be set by calibration.

[0023] [Functional Configuration] Figure 5 is a block diagram showing the functional configuration formed in the control unit 100. As shown in Figure 5, the control unit 100 includes an integrated control unit 100A, an adhesive material supply roller control unit 110, tension adjustment roller control units 120A and 120B, a half-cut roller control unit 130, a backup roller control unit 140, a peel suppression control unit 150, an unwanted material winding roller control unit 160, a film substrate supply roller control unit 170, a protective film winding roller control unit 180, and laminating roller control units 190A and 190B.

[0024] The integrated control unit 100A controls the entire lamination process, controlling the transport speed of the sheet-like laminate S and film substrate F, the winding speed of the separator to which the die-cut area of ​​the film is attached, the protective film, and the film substrate F' to which the film (frame portion) is attached. The integrated control unit 100A also controls the half-cut shape of the film by the half-cut roller 30 so that it is the set shape. Furthermore, the integrated control unit 100A controls the peel-inhibition process (pressing operation by the pressing member 50A) in the peel-inhibition unit 50 to make it difficult for the die-cut area of ​​the film to peel off from the separator. The adhesive material supply roller control unit 110 drives the first actuator 11 according to the instructions of the integrated control unit 100A to rotate the adhesive material supply roller 10.

[0025] The tension adjustment roller control units 120A and 120B drive the second actuator 21A and the third actuator 21B in accordance with the instructions of the integrated control unit 100A, and rotate the tension adjustment rollers 20A and 20B. The tension adjustment roller control units 120A and 120B rotate the tension adjustment rollers 20A and 20B so that appropriate tension is applied to the sheet-like laminate S in accordance with the operation of the half-cut roller 30 to half-cut the sheet-like laminate S. The half-cut roller control unit 130 drives the fourth actuator 31 in accordance with the instructions of the integrated control unit 100A, and rotates the half-cut roller 30. The half-cut roller control unit 130 rotates the half-cut roller 30 at a speed corresponding to the half-cut shape set by the integrated control unit 100A.

[0026] The backup roller control unit 140 drives the fifth actuator 41 in accordance with the instructions of the integrated control unit 100A to rotate the backup roller 40 and transport the sheet-like laminate S at a predetermined speed. The peeling suppression control unit 150 drives the sixth actuator 51 in accordance with the instructions of the integrated control unit 100A to press the pressing member 50A against the die-cutting area of ​​the film. The unwanted material winding roller control unit 160 drives the seventh actuator 61 in accordance with the instructions of the integrated control unit 100A to rotate the unwanted material winding roller 60.

[0027] The film substrate supply roller control unit 170 drives the eighth actuator 71 in accordance with the instructions of the integrated control unit 100A to rotate the film substrate supply roller 70 and feeds out the film substrate F at a speed that matches the rate at which the sheet-like laminate S is supplied. The protective film winding roller control unit 180 drives the ninth actuator 81 in accordance with the instructions of the integrated control unit 100A to rotate the protective film winding roller 80. The laminating roller control units 190A and 190B drive the tenth actuator 91A and the eleventh actuator 91B in accordance with the instructions of the integrated control unit 100A to rotate the laminating rollers 90A and 90B.

[0028] [Operation] Next, the operation of the laminator 1 will be explained. Figure 6 is a flowchart showing the flow of the lamination process performed by the laminator 1. As shown in Figure 6, when the lamination process is started, in step S1, the integrated control unit 100A starts the rotation of the first to eleventh actuators 11, 21A, 21B, 31, 41, 51, 61, 71, 81, 91A, and 91B, thereby starting the transport of the sheet-like laminate S.

[0029] In step S2, the half-cut roller control unit 130 rotates the half-cut roller 30 at a speed corresponding to the half-cut shape set by the integrated control unit 100A. In step S3, the peel-inhibition control unit 150 presses the pressing member 50A of the peel-inhibition unit 50 against the die-cut area of ​​the half-cut film, making it difficult for the die-cut area to peel away from the separator. In step S4, the laminating rollers 90A and 90B clamp and press together the frame portion of the film that has been half-cut by the half-cut roller 30 and the film substrate F supplied from the film substrate supply roller 70.

[0030] In step S5, the integrated control unit 100A determines whether or not the lamination process on the film substrate F is complete. If the lamination process on the film substrate F is not complete, the determination in step S5 is NO, and the process proceeds to step S2. On the other hand, if the lamination process on the film substrate F is complete, the determination in step S5 is YES, and the lamination process ends.

[0031] As described above, the laminator 1 according to this embodiment first processes the half-cut film to make it difficult to peel off the portion that is not to be peeled (die-cut area) from the separator (peeling suppression treatment), and then peels off the portion of the film that is to be peeled off (frame portion) from the separator. Then, it laminates the film peeled off from the separator onto the film substrate F to complete the desired lamination process. Therefore, the adhesive strength of the portion of the film that is not to be peeled off (die-cut area) to the separator is increased, and it is possible to make it difficult to peel off the film other than the portion that is to be peeled off from the separator. Thus, it is possible to realize a technology that can more appropriately peel off the portion to be peeled off from a half-cut sheet-like member.

[0032] [Modification 1] In the above embodiment, a process (peeling suppression treatment) was performed to make it difficult for the film other than the portion attached to the film substrate F of the sheet-like laminate S (die-cut area) to peel off from the separator by pressing the film against the separator with a pressing member 50A. However, other processing methods are also possible as long as the film that is not to be peeled off becomes difficult to peel off from the separator.

[0033] Figure 7 is a schematic diagram showing an example of a processing method that forms an indentation to make it difficult for the die-cut area of ​​the film to peel off from the separator. As shown in Figure 7, the peel suppression unit 50 is equipped with an indentation forming member 50B instead of a pressing member 50A, and by striking the indentation forming member 50B against the sheet-like laminate S with the sixth actuator 51, an indentation that deforms the film and separator can be formed. The indentation forming member 50B is composed of a tool having a predetermined tip shape (for example, hemispherical), and when struck against the sheet-like laminate S, it forms an indentation (concave deformation) on the film and separator that corresponds to the tip shape. As the film and separator are deformed integrally by the formation of the indentation, it becomes difficult for the film and separator to peel off, and the unnecessary peeling of the portion of the film that is not to be peeled off (die-cut area) from the separator can be more reliably suppressed.

[0034] Figure 8 is a schematic diagram showing an example of a processing configuration in which a perforation is formed to make it difficult for the die-cut area of ​​the film to peel off from the separator. As shown in Figure 8, the peel suppression unit 50 is equipped with a perforation forming member 50C instead of a pressing member 50A, and by piercing the perforation forming member 50C into the sheet-like laminate S with the sixth actuator 51, a perforation that penetrates the film and the separator can be formed. The perforation forming member 50C is composed of a tool having a predetermined tip shape (for example, a sharp cone or pyramidal tip), and when pierced into the sheet-like laminate S, it forms a perforation (through hole) that penetrates the film and the separator. As a result of the formation of the perforation, the film and the separator deform integrally and fit into the shape of the hole, making it difficult for the film and the separator to peel off, and more reliably suppressing the unnecessary peeling of the portion of the film that is not to be peeled off (die-cut area) from the separator.

[0035] [Modified Example 2] In the above-described embodiment and modified example, in order to make it difficult for the film (die-cut area) other than the portion of the sheet-like laminate S attached to the film substrate F to peel off from the separator, peel-inhibiting treatments such as pressing the film against the separator, forming indentations that deform the film and separator, and forming perforations that penetrate the film and separator were performed. In contrast, it is possible to perform peel-inhibiting treatment on the film in a manner other than processing the film or separator.

[0036] Figures 9A to 9C are schematic diagrams showing an example of a configuration in which peeling suppression processing is performed using an auxiliary member 50D that holds the film to prevent the die-cut area of ​​the film from peeling off the separator. Figure 9A is a perspective view, Figure 9B is a front view, and Figure 9C is a side view. In Figures 9A and 9B, the parts of the die-cut area shown with dashed lines represent the state in which the frame area is held by the separator, and the parts of the die-cut area shown with solid lines represent the state in which the frame area has peeled off the separator. Figures 9A to 9C show an example in which the auxiliary member 50D is equipped with a roller having a width slightly smaller than the width of the die-cut area of ​​the film. In the configuration shown in Figures 9A to 9C, when the die-cut area of ​​the film is transported to a predetermined position, the pressing member 50D presses the die-cut area against the separator (backup roller 40), and when not performing this operation, the pressing member 50D is retracted away from the backup roller 40.

[0037] As shown in Figures 9A to 9C, as a peel-inhibiting treatment to make it difficult for the die-cut area of ​​the film to peel off from the separator, the die-cut area of ​​the film is pressed against the separator by the pressing member 50D. When the film is peeled off from the separator, the frame portion attached to the film substrate F peels off from the separator, while the die-cut area remains adhered to the separator, allowing only the necessary portion to be appropriately peeled off from the separator. Furthermore, by using a roller as the auxiliary member 50D, the state in which the die-cut area of ​​the film remains adhered to the separator can be maintained without placing a large load on the film and the separator. The position in which the auxiliary member 50D is pressed against the separator can be, for example, immediately before or immediately after the frame portion is peeled off from the separator. In this modified example, the case in which the pressing member 50D is configured as a roller has been described as an example, but any simple member that can press down on the die-cut area of ​​the film, such as a rod, may be used.

[0038] [Modified Example 3] In addition to the embodiments and modified examples described above, it is possible to perform thermal processing as a peel-inhibiting treatment to make it difficult for the film other than the portion attached to the film substrate F (die-cut region) to peel off from the separator. For example, in a half-cut sheet-like laminate S, it is possible to perform a peel-inhibiting treatment in which the die-cut region of the film is welded to the separator by heat before the frame portion of the film peels off from the separator. As an example, a device for welding the die-cut region of the film to the separator by heat can be provided at the position of the peel-inhibiting section 50 shown in Figure 1. As processing methods for welding the die-cut region of the film to the separator by heat, thermal welding by pressing an ultrasonic horn against the film (ultrasonic welding), thermal welding by applying heat to the film with a laser, thermal welding by bringing a heater (heating iron, etc.) into contact with the film can be used. By thermal welding the die-cut region of the film to the separator, it is possible to more reliably suppress the unnecessary peeling of the portion of the film that is not to be peeled off (die-cut region) from the separator.

[0039] [Modification 4] In the above-described embodiment and modification, it is possible to pre-treat the film before it is half-cut in the area that is to become the die-cutting area after half-cutting. For example, in the film before it is half-cut, the pressing member 50A can be pressed against the film and separator, or indentations or perforations can be formed in the film and separator, or the film can be heat-sealed to the separator in the area that is to become the die-cutting area after half-cutting. By performing peel-resistance treatment on the film before it is half-cut, the degree of freedom in arranging the mechanism for performing peel-resistance treatment can be increased.

[0040] The embodiments and modifications described above are examples of embodiments of the present invention, and various embodiments that realize the functions of the present invention are included within the scope of the present invention. For example, in the embodiments and modifications described above, the position of the sheet-like laminate S that is processed or treated by the peel-suppression unit 50 to make it difficult for the film to peel off from the separator can be appropriately set within a range that can suppress the unnecessary peeling of film that is not to be peeled off. As an example, in the sheet-like laminate S, processing may be performed on the portion that is not to be peeled off located downstream in the transport direction, relative to the position half-cut by the half-cut roller 30 with an etching blade (or engraving blade, etc.) along the generatrix of the outer surface, while processing may not be performed on the portion that is not to be peeled off located upstream in the transport direction. This makes it possible to efficiently perform processing by the peel-suppression unit 50 on the portion of the film in the sheet-like laminate S that is likely to be unnecessarily peeled off.

[0041] Furthermore, in the sheet-like laminate S, the peel-inhibiting section 50 may be used to process the portion of the sheet-like laminate S that is not to be peeled, which has been half-cut by the etching blade (or engraving blade, etc.) of the half-cut roller 30, along the half-cut cutting line. In addition, the peel-inhibiting section 50 may be used to process the entire surface of the portion of the sheet-like laminate S that is not to be peeled, which has been half-cut by the etching blade (or engraving blade, etc.) of the half-cut roller 30. This makes it possible to more reliably suppress the unnecessary peeling of the portion of the film that is not to be peeled from the separator in the sheet-like laminate S.

[0042] Furthermore, when performing delamination suppression treatment, it is possible to perform the treatment while continuously transporting the sheet-like laminate S, or it is also possible to perform the treatment while temporarily stopping or temporarily reducing the transport speed of the sheet-like laminate S. This makes it possible to perform the treatment in an appropriate process depending on the characteristics of the sheet-like laminate S and the form of the delamination suppression treatment.

[0043] As described above, the laminator 1 in the present embodiment includes a half-cut roller 30, a backup roller 40, a peeling prevention unit 50, and laminating rollers 90A and 90B. The half-cut roller 30 and the backup roller 40 cut only the attachment member of the sheet-like member (sheet-like laminate S) in which the base material (separator) and the attachment member (film) are laminated. The peeling prevention unit 50 performs a peeling prevention process for suppressing the peeling of the first portion (die-cut area), which is not a peeling target from the base material, from the base material among the attachment members cut by the half-cut roller 30 and the backup roller 40 or the portions of the attachment members to be cut. The laminating rollers 90A and 90B attach the second portion (frame portion) peeled from the base material among the attachment members cut by the half-cut roller 30 and the backup roller 40 to the workpiece. Thereby, it is possible to make it difficult for the first portion (die-cut area), which is not a peeling target of the film, to be peeled from the base material (separator) by the peeling prevention process. Therefore, it is possible to realize a technique capable of more appropriately peeling the portion to be peeled from the half-cut sheet-like member.

[0044] The peeling prevention unit 50 performs a peeling prevention process on a position near the cutting line half-cut in a direction intersecting the conveyance direction of the sheet-like member in the first portion of the attachment member half-cut by the half-cut roller 30 and the backup roller 40 or the attachment member to be cut. Thereby, it becomes possible to perform a process for suppressing the peeling of the first portion (die-cut area) from the base material with respect to a portion that is easily peeled uselessly in the attachment member.

[0045] The peeling prevention unit 50 performs a peeling prevention process on a position on the downstream side in the conveyance direction of the cutting line half-cut in a direction intersecting the conveyance direction of the sheet-like member in the first portion of the attachment member half-cut by the half-cut roller 30 and the backup roller 40 or the attachment member to be cut. Thereby, it becomes possible to efficiently perform a process for suppressing the peeling of the first portion from the base material with respect to a portion that is easily peeled uselessly in the attachment member.

[0046] The peeling prevention part 50 performs a peeling prevention process by pressing the first part against the base material. As a result, it is possible to make it difficult for the first part to peel from the base material with a simple operation. [[ID=​2]]

[0047] The peeling prevention part 50 performs a peeling prevention process by forming a concave deformation in the first part. As a result, it is possible to more reliably prevent the first part from peeling uselessly from the base material.

[0048] The peeling prevention part 50 performs a peeling prevention process by forming a perforation in the first part. As a result, it is possible to more reliably prevent the first part from peeling uselessly from the base material.

[0049] The peeling prevention part 50 performs a peeling prevention process by pressing the first part against the base material when the second part peels from the base material. As a result, it is possible to more reliably prevent the first part from peeling uselessly from the base material.

[0050] The peeling prevention part 50 performs a peeling prevention process by welding the first part to the base material by heat. As a result, it is possible to more reliably prevent the first part from peeling uselessly from the base material.

[0051] After the sticking member is cut by the half-cut roller 30 and the backup roller 4​0, the distance that the sticking member peeled from the base material is bridged from the upstream backup roller 40 to the downstream laminating roller 90A is within one pitch of the shape cut by the half-cut roller 30 and the backup roller 40. As a result, even when the second part peels from the base material and is separated from the first part, it is possible to suppress a situation where it shrinks in the width direction due to the tension applied in the conveying direction and wrinkles occur.

[0052] The half-cut roller 30 and the backup roller 40 cut the sticking member of the sheet-like member into shapes with different lengths in the conveying direction. The peeling prevention part 50 performs a peeling prevention process in accordance with the shape of the sticking member half-cut by the half-cut roller 30 and the backup roller 40. As a result, in the sticking member half-cut into various shapes, it is possible to appropriately prevent the first part from peeling uselessly from the base material.

Furthermore, the effects described in these embodiments are merely a list of the most preferred effects arising from the present invention, and the effects of the present invention are not limited to those described in these embodiments.
