Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the mechanism described in Patent Document 1, since the peripheral surface of the roll body needs to always maintain a constant adhesive state, maintenance of the roll body has been required. In addition, a mechanism for preventing the protective film from adhering to the discharge means in the process of transporting the protective film peeled off by the claw body has been required.

[0006] The present invention solves the above conventional problems, and aims to provide a film peeling device that does not require a roll body having an adhesive peripheral surface and can prevent the film from adhering to the discharge means.

Means for Solving the Problems

[0007] To solve the aforementioned conventional problems, the invention of claim 1 provides a film peeling device for peeling a film from a laminate having a base material and a film attached to at least one surface of the base material, wherein the film peeling device has a transport table on which the laminate is placed, a transport means capable of transporting the laminate in the transport direction, a rotating shaft, a brush member, a first rotating brush that rotates while in contact with the laminate and peels the film from the laminate, and a device provided near the first rotating brush to suppress the adhesion of the film to the first rotating brush The device comprises a regulating member and a discharge means that rotates while in contact with the peeled film and can transport the film to a discharge port, wherein the first rotating brush rotates in the opposite direction to the transport direction at the contact position with the laminate to peel the film from the substrate, a groove is formed on the outer circumferential surface of the first rotating brush, and the regulating member is characterized by having comb teeth inserted into the groove of the first rotating brush and a substantially plate-shaped wall integrally formed with the comb teeth and guiding the film toward the discharge means.

[0008] The invention of claim 1 eliminates the need for a conventional roll body with an adhesive surface by using a first rotating brush to peel the film from the laminate. Furthermore, the first rotating brush rotates in the opposite direction to the transport direction at the contact position with the laminate, and has a comb-like structure inserted into the groove of the first rotating brush, and a substantially plate-shaped wall integrally formed with the comb-like structure that guides the film toward the discharge means. This ensures that the wall reliably guides the film toward the discharge means, and prevents the adhesive side of the film from contacting the discharge means, thereby preventing the film from adhering to the discharge means. In addition, the arrangement of the discharge means can be freely selected by changing the direction of the wall.

[0009] The invention of claim 2 is characterized in that, in the invention of claim 1, the regulating member is positioned opposite the laminate with the first rotating brush in between, and the wall is formed such that its longitudinal direction is substantially parallel to the longitudinal direction of the rotation axis of the first rotating brush, and its short direction is substantially perpendicular to the conveying direction of the laminate or inclined in the opposite direction to the conveying direction. This prevents the peeled film from adhering to the first rotating brush, guides the adhesive side of the film so that it does not come into contact with the discharge means, and allows the arrangement of the discharge means to be determined by the short direction of the wall.

[0010] The invention of claim 3 is characterized in that, in the invention of claim 1, the regulating member is positioned opposite the laminate with the first rotating brush in between, and the wall has a longitudinal direction substantially parallel to the longitudinal direction of the rotation axis of the first rotating brush, and a short direction extending in the tangential direction of the circumscribed circle of the first rotating brush. This prevents the peeled film from adhering to the first rotating brush and prevents the film from folding or bending by allowing it to peel off smoothly from the first rotating brush. Furthermore, the arrangement of the discharge means can be determined by the short direction of the wall.

[0011] The invention of claim 4 is characterized in that, in the invention of claim 1, the regulating member is positioned opposite the laminate with the first rotating brush in between, and the wall has a longitudinal direction substantially parallel to the longitudinal direction of the rotation axis of the first rotating brush, and when viewed from a side view substantially perpendicular to the transport direction of the laminate, the wall extends to a position overlapping with the discharge means. This ensures that the peeled film is reliably guided to the discharge means.

[0012] The invention of claim 5 is characterized in that, in any of the inventions of claims 1 to 4, the regulating member is formed with comb teeth bent relative to the wall, and the tips of the comb teeth extend to the vicinity of the bottom surface of the groove of the first rotating brush. This prevents the peeled film from adhering to the brush member of the first rotating brush and the rotating shaft, and also allows adjustment of the appropriate direction for the comb teeth to peel the film from the first rotating brush and the appropriate direction for the wall to guide the film to the discharge means.

[0013] The invention of claim 6 is characterized in that, in the invention of claim 1, the first rotating brush has a brush member formed of a plurality of bristles formed on the outer circumferential surface of the rotating shaft, and the longitudinal direction of the bristles is inclined toward the rotation direction side of the first rotating brush. This makes it easier for the tips of the bristles to enter between the film and the substrate, and the film can be easily peeled off.

[0014] The invention of claim 7 is characterized in that, in the invention of claim 6, the first rotating brush contacts the laminate while being biased from a direction substantially perpendicular to the conveying direction with respect to the laminate, and the plurality of bristles are formed of twisted wire. This makes it easier for the tips of the bristles to enter between the film and the substrate, and makes it easier to peel off the film.

[0015] The invention of claim 8 is characterized in that, in the invention of claim 1, the discharge means also serves as a conveying means and is located near the first rotating brush. This makes the film peeling device more compact and reduces manufacturing costs.

[0016] The invention of claim 9 is characterized in that, in the invention of claim 1, the discharge means has a film recovery means formed near the end on the discharge direction side. This makes it possible to easily recover the peeled film.

[0017] The invention of claim 10 is characterized in that, in the invention of claim 9, the discharge means comprises a second rotating brush and a guide member that contacts the second rotating brush and guides the film away from the second rotating brush to the film recovery means. This allows the peeled film to be easily transferred to the film recovery means by the second rotating brush and the guide member. [Effects of the Invention]

[0018] The invention of the film peeling device according to claim 1 can be configured without requiring a conventional roll body having an adhesive surface, and can prevent the film from adhering to the discharge means. Furthermore, the arrangement of the discharge means can be freely selected by changing the direction of the wall. The inventions according to claims 2 and 3 can prevent the peeled film from adhering to the first rotating brush, and the arrangement of the discharge means can be determined by the short-side direction of the wall. Furthermore, the invention according to claim 4 can reliably guide the peeled film to the discharge means.

[0019] The invention of claim 5 can prevent the peeled film from adhering to the brush member and the rotating shaft of the first rotating brush. Furthermore, the inventions of claims 6 and 7 can make it easier for the tip of the bristles to enter between the film and the substrate, and the film can be easily peeled off.

[0020] The invention of claim 8 allows for a more compact film peeling device, thereby reducing manufacturing costs. Furthermore, the invention of claim 9 allows for easy recovery of the peeled film. Furthermore, the invention of claim 10 allows for easy transfer of the peeled film to a film recovery means. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited by this embodiment. FIG. 1 is a front view showing the first embodiment of the film peeling device according to the present invention, FIG. 2(a) is a perspective view of the first rotating brush constituting the film peeling device of the first embodiment, FIG. 2(b) is a perspective view of the regulating member constituting the film peeling device of the first embodiment, and FIG. 2(c) is a perspective view of the state in which the first rotating brush and the regulating member are combined. Further, FIG. 3 is a front view showing the state where the first rotating brush constituting the film peeling device of the first embodiment is in contact with the film. The first embodiment of the film peeling device according to the present invention will be described below using these figures.

[0023] The film peeling apparatus 10 of the first embodiment is an apparatus for peeling a film 32 from a laminate 33 having a base material 31 and a film 32 attached to at least one surface of the base material 31, and has a transport table 1a, 2a, 3a on which the laminate 33 is placed, a transport means 1, 2, 3 that can transport the laminate 33 in the transport direction, a rotating shaft 4, a brush member 5, a first rotating brush 6 that rotates while in contact with the laminate 33 and peels the film 32 from the laminate 33, a regulating member 7 provided near the first rotating brush 6 to suppress the adhesion of the film 32 to the first rotating brush 6, and a discharge means 8 that rotates while in contact with the peeled film 32 and can transport the film to a discharge port.

[0024] The first rotating brush 6 rotates in the opposite direction to the transport direction when it comes into contact with the laminate 33, peeling the film 32 from the base material 31. A groove 6a is formed on the outer circumferential surface of the first rotating brush 6. The regulating member 7 has comb teeth 7a that are inserted into the groove 6a of the first rotating brush 6, and a substantially plate-shaped wall 7b that is integrally formed with the comb teeth 7a and guides the film 32 toward the discharge means 8.

[0025] The film peeling device 10 of the first embodiment is configured to peel the film from the laminate using a first rotating brush, thus eliminating the need for a conventional roll body with an adhesive surface. Furthermore, the first rotating brush 6 rotates in the opposite direction to the transport direction at the contact position with the laminate 33, and has a comb-like structure 7a inserted into the groove 6a of the first rotating brush 6, and a substantially plate-shaped wall 7b integrally formed with the comb-like structure 7a that guides the film 32 toward the discharge means 8. This ensures that the wall 7b reliably guides the film toward the discharge means 8, and prevents the adhesive side of the film 32 from contacting the discharge means 8, thereby preventing the film 32 from adhering to the discharge means 8. In addition, the arrangement of the discharge means 8 can be freely selected by changing the direction of the wall 7b.

[0026] The regulating member 7 is positioned opposite the laminate 33 with the first rotating brush 6 in between, and the wall 7b has a longitudinal direction that is substantially parallel to the longitudinal direction of the rotation axis 4 of the first rotating brush 6, and when viewed from the side that is substantially perpendicular to the transport direction of the laminate 33, the wall 7b extends to a position that overlaps with the discharge means 8. This ensures that the peeled film 32 is reliably guided to the discharge means 8.

[0027] The regulating member 7 is formed with comb teeth 7a bent relative to the wall body 7b, and the tips of the comb teeth 7a extend to near the bottom surface of the groove 6a of the first rotating brush 6. This prevents the peeled film 32 from adhering to the brush member 5 of the first rotating brush 6 and the rotating shaft 4, and also allows adjustment of the appropriate direction for the comb teeth 7a to peel the film 32 from the first rotating brush 6 and the appropriate direction for the wall body 7b to guide the film 32 to the discharge means 8.

[0028] The first rotating brush 6 has a brush member 5 formed of multiple bristles 5a, 5a... formed on the outer circumferential surface of the rotating shaft 4, and the longitudinal direction of the bristles 5a is inclined toward the direction of rotation of the first rotating brush 6 (arrow A in Figure 1). This makes it easier for the tips of the bristles 5a to enter between the film 32 and the substrate 31, and the film 32 can be easily peeled off.

[0029] Figure 4(a) is a front view showing a second embodiment in which the first rotating brush and the regulating member are combined. The regulating member 17 shown in this figure is positioned opposite the laminate 33 with the first rotating brush 6 in between, and the wall 17b has its longitudinal direction substantially parallel to the longitudinal direction of the rotation axis 4 of the first rotating brush 6, and its short direction extends in the tangential direction of the circumscribed circle of the first rotating brush 6. This prevents the peeled film 32 from adhering to the first rotating brush 6, and prevents the film 32 from folding or bending by allowing it to peel off smoothly from the first rotating brush 6. Furthermore, the arrangement of the discharge means can be determined by the short direction of the wall 17b.

[0030] Figure 4(b) is a front view showing a third embodiment in which the first rotating brush and the regulating member are combined. The regulating member 27 shown in this figure is positioned opposite the laminate 33 with the first rotating brush 6 in between, and the wall 27b is formed such that its longitudinal direction is substantially parallel to the longitudinal direction of the rotation axis 4 of the first rotating brush 6, and its short direction is inclined substantially perpendicular to the conveying direction of the laminate 33. Alternatively, the wall 27b may be formed such that its longitudinal direction is substantially parallel to the longitudinal direction of the rotation axis 4 of the first rotating brush 6, and its short direction is inclined in the opposite direction to the conveying direction of the laminate 33. This prevents the peeled film 32 from adhering to the first rotating brush 6, and the arrangement of the discharge means can be determined by the short direction of the wall 27b.

[0031] Figure 5(a) is a perspective view showing a second embodiment of the bristles, in which multiple bristles 5b, 5b... are arranged in a straight line in the longitudinal direction. Figure 5(b) is a perspective view showing a third embodiment of the bristles, in which multiple bristles 5c, 5c... are arranged in a wavy pattern in the longitudinal direction. Figure 5(c) is a perspective view showing a fourth embodiment of the bristles, in which multiple bristles 5d, 5d... are bundled together in a spiral pattern in the longitudinal direction to form a twisted wire. As a result, when multiple bristles 5b, 5b... are arranged in a straight line in the longitudinal direction, the bristles become stiffer, making it easier to peel off the film 32. Also, when multiple bristles 5c, 5c... are arranged in a wavy pattern in the longitudinal direction, flexibility is improved, preventing damage to the surface of the film 32. Furthermore, when multiple bristles 5d, 5d... are bundled together in a spiral in the longitudinal direction to form a twisted wire, the multiple bristles support each other, resulting in increased stiffness and improved flexibility. This makes it easier to peel off the film 32 and prevents damage to the surface.

[0032] Figure 6 is a front view showing a second embodiment of the film peeling device according to the present invention. In the film peeling device 20 of the second embodiment, the first rotating brush 16 is biased by a biasing means 16a from a direction substantially perpendicular to the conveying direction relative to the laminate and contacts the laminate, and is made of a stranded wire in which a plurality of bristles 5d, 5d... are bundled together in a spiral in the longitudinal direction (see Figure 5(c)). This makes it easier for the tips of the plurality of bristles 5d, 5d... to enter between the film 32 and the base material 31, and the film 32 can be peeled off even more easily. Furthermore, by employing the biasing means 16a, the first rotating brush 16 can be pressed against the laminate 33 with appropriate force, and by employing the stranded bristles 5d, the cushioning properties of the bristles 5d allow the tips of the bristles 5d to follow the irregularities on the surface of the laminate 33, and the film 32 can be peeled off from the base material 31 with appropriate force.

[0033] Furthermore, the discharge means 28 also serves as a conveying means and is located near the first rotating brush 16, with a film recovery means 9 formed near the end on the discharge side. This makes the film peeling device 20 more compact, reducing manufacturing costs, and allows for easy recovery of the peeled film 32.

[0034] Furthermore, the discharge means 28 includes a second rotating brush 26 and a guide member 47 that contacts the second rotating brush 26 and guides the film 32 away from the second rotating brush 26 to the film recovery means 9. This allows the peeled film 32 to be easily transferred to the film recovery means 9 by the second rotating brush 26 and the guide member 47. Reference numeral 11 denotes a mounting table on which the laminate 33 is placed, and since the discharge means 28 also serves as a transport means, the transport means 1 that constitutes the film peeling device 10 of the first embodiment is not required. The other configurations are the same as those of the film peeling device 10 of the first embodiment, so their description is omitted. [Industrial applicability]
