[Technical Field]

[0001] The present invention relates to a removal device and a removal method for removing deposits adhering to a film substrate made of synthetic resin. [Background technology]

[0002] Patent Document 1 describes an adhering material removal device that includes a feeding mechanism that feeds out a rectangular sheet material and a winding mechanism that winds up the sheet material. This adhering material removal device includes a pressing member that presses the sheet material from the back side, a wide-area air nozzle, and a partial air nozzle. The wide-area air nozzle blows air toward the front side of the folded sheet material, across an area spanning from one side to the other in the width direction of the sheet material. The partial air nozzle blows air toward both sides of the width direction of the sheet material. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2024-020961 Summary of the Invention [Problem to be solved by the invention]

[0004] When the removal method described in Patent Document 1 is carried out, it may be difficult to remove the deposits from a sheet member or film substrate made of synthetic resin. Specifically, the deposits may not be easily removed at the interface between the sheet member or film substrate and the deposits. In this case, the deposits are not removed, and air cannot be blown onto the interface, making it difficult to remove the deposits.

[0005] Furthermore, it may be difficult to form a gap between the sheet member or film substrate and the deposit at the interface. In this regard, the gap between the two can trigger the deposit to peel off. Therefore, when a gap is difficult to form, air cannot be blown to the interface, making it difficult to remove the deposit. Therefore, there is a need for an apparatus and method for efficiently and reliably peeling and removing the deposit. [Means for solving the problem]

[0006] A removal device according to one embodiment is a removal device for removing deposits adhering to a film substrate made of a synthetic resin, the removal device comprising: a conveying means for conveying the film substrate; The cleaning device further includes a first brush that contacts the film substrate while being transported in order to remove the deposits from the film substrate.

[0007] Further, a removal method according to another embodiment is a method for removing an attachment adhering to a film substrate made of a synthetic resin, the method comprising: Transporting the film substrate; bringing a first brush into contact with the film substrate being transported to remove the deposits from the film substrate; blowing gas onto the film substrate after contact with the first brush to remove the deposits from the film substrate; The peeled off deposits are collected. [Effects of the Invention]

[0008] This allows the deposits to be peeled off from the film substrate more efficiently and reliably, and the peeled deposits to be removed. [Brief explanation of the drawings]

[0010] Hereinafter, exemplary embodiments for carrying out the present invention will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, and relative positions of components described in the following embodiments can be arbitrarily set and can be changed depending on the configuration or various conditions of the device or method to which the present invention is applied. Furthermore, unless otherwise specified, the scope of the present invention is not limited to the embodiments specifically described below.

[0011] [First embodiment] A removal device 100 for removing deposits from a film substrate 10 made of synthetic resin will be described with reference to Fig. 1. Fig. 1 is a configuration diagram of the removal device 100 according to the first embodiment. Fig. 1 also shows a schematic representation of the devices and members constituting the removal device 100.

[0012] For example, the synthetic resin constituting the film substrate 10 is polyethylene terephthalate. As other examples, the synthetic resin may be a polyester resin, a polyolefin resin such as a polypropylene resin or a polyethylene resin, an acrylic resin such as a polylactic acid resin, a polycarbonate resin, a polymethyl methacrylate resin or a polystyrene resin, a polyamide resin, a polyvinyl chloride resin, a polyurethane resin, a fluorine-based resin, or a polyphenylene sulfide resin. In the following description, an example in which the film substrate 10 is made of polyethylene terephthalate will be mainly described.

[0013] The thickness of the film substrate 10 is 10 μm or more and 100 μm or less, and more preferably 20 μm or more and 50 μm or less. An attachment is attached to the film substrate 10. For example, the film substrate 10 is a substrate used as a carrier film when manufacturing a multi-layer ceramic capacitor. A green sheet including an inorganic paste layer is printed on such a carrier film as the attachment.

[0014] Typically, carrier films used in manufacturing are discarded with the green sheet still attached. However, if the green sheet residue remaining on the carrier film can be removed, the carrier film can be effectively used as a recycled material. Therefore, the removal device 100 removes attachments such as green sheet residue from a film substrate 10 such as a carrier film. This allows the film substrate 10 from which the attachments have been removed to be effectively used as a recycled material.

[0015] As an example, a release layer is formed on a film substrate 10 serving as a carrier film using a coating liquid containing a curable silicone resin. For example, the release layer is formed by drying and curing the applied coating liquid. Then, a green sheet is formed on the release layer. For example, the green sheet serves as the basis for a dielectric and electrodes. As an example, the dielectric is formed using a dielectric material such as calcium titanate, strontium titanate, or barium titanate. Furthermore, as an example, the electrode is formed using palladium, silver, nickel, aluminum, zinc, tin, copper, or an alloy thereof.

[0016] Alternatively, the film substrate 10 may be a substrate used in the manufacture of a wound film capacitor. The layer constituting the deposit may be a single layer or multiple layers. The following description will mainly focus on an example in which the film substrate 10 is a carrier film used in the manufacture of a multilayer ceramic capacitor. In this case, the deposit is a residue of a green sheet, but dust or dirt may also be included in the deposit.

[0017] Returning to FIG. 1, the removing device 100 includes a feed unit 20, which is an example of a conveying means for conveying the film substrate 10. The feed unit 20 holds a substrate roll 11 formed by winding the film substrate 10 around a central shaft 10C. The feed unit 20 also includes a pair of feed rollers 21 that sandwich and feed the film substrate 10.

[0018] Each roller of the feed roller pair 21 is a drive roller that is rotationally driven by a drive device. For example, the drive device includes an AC motor and a powder clutch as an actuator connected to the AC motor. The drive roller is connected to the powder clutch. Alternatively, one of the feed roller pair 21 may be a driven roller that rotates with the rotation of the drive roller. The feed unit 20 also includes a plurality of rollers 22 that guide the film substrate 10 pulled out from the substrate roll 11. The film substrate 10 guided by the rollers 22 is then fed by the feed roller pair 21.

[0019] The delivery unit 20 also has a pair of guide rollers 23 that guide the film substrate 10, which has been pulled out from the substrate roll 11, to the pair of delivery rollers 21. The pair of guide rollers 23 are driven rollers that rotate as the film substrate 10 moves. However, at least one of the pair of guide rollers 23 may be a drive roller. As another example of the conveying means, the removing device 100 may be provided with a pull-out unit that pulls out the film substrate 10 from the substrate roll 11.

[0020] The removal device 100 also includes a peeling unit 30 as an example of a removal means for peeling off deposits from the film substrate 10. The removal device 100 also includes a first brush 31 included in the peeling unit 30. This first brush 31 comes into contact with the film substrate 10 being transported in order to peel off deposits from the film substrate 10. For example, the first brush 31 rotates while in contact with the film substrate 10. This causes the numerous brush bristles included in the first brush 31 to physically peel off the deposits from the film substrate 10. Alternatively, the film substrate 10 may move relative to the first brush 31, thereby physically peeling off the deposits from the film substrate 10.

[0021] For example, the first brush 31 is a hard brush made of hard resin. Examples of hard resin include nylon, polypropylene, polyvinyl chloride, and polyester. Furthermore, the first brush 31 may be a non-charged brush or a charge-removing brush. This prevents the removed deposits from adhering to the brush bristles. The first brush 31 may also be a roll brush. In this case, the removal device 100 includes a drive device that is included in the removal unit 30 and rotates the roll brush.

[0022] Furthermore, the peeling unit 30 has an opposing roller 32 that faces the first brush 31 with the film substrate 10 sandwiched between them. As an example, the opposing roller 32 is a rubber roller or a metal roller. The opposing roller 32 is a driven roller that rotates as the film substrate 10 moves, but it may also be a drive roller. Alternatively, instead of the opposing roller 32, the peeling unit 30 may have an opposing plate that faces the first brush 31 with the film substrate 10 sandwiched between them.

[0023] Alternatively, the first brush 31 may be a cup brush. In this case, the removal device 100 includes a traverse mechanism that winds up the film substrate 10. The traverse mechanism reciprocates the film substrate 10 relative to the winding shaft in the width direction perpendicular to the conveyance direction of the film substrate 10. In this way, the traverse mechanism winds up the film substrate 10 evenly. The cup brush comes into contact with the film substrate 10 as it is being wound up, removing any adhering material.

[0024] Furthermore, a plurality of first brushes 31 may be provided. For example, a further first brush 31 may be provided that contacts the opposite surface of the film substrate 10. This first brush 31 removes any deposits that have re-adhered to the opposite surface of the film substrate 10. Note that, in the film substrate 10, the surface that contacts the first brush 31 is the front surface, and the surface opposite the front surface is the opposite surface. Therefore, when a plurality of first brushes 31 contact both surfaces, the surface that contacts any one of the first brushes 31 is the front surface.

[0025] The removal device 100 includes a blower 33 in the peeling unit 30. The blower 33 blows gas onto the film substrate 10 after it has come into contact with the first brush 31 in order to peel off the deposits from the film substrate 10. For example, the blower 33 blows air onto the front of the film substrate 10 from an outlet extending in the width direction of the film substrate 10. This causes air to enter the gap created by the first brush 31 between the film substrate 10 and the deposits. As a result, the deposits that were not peeled off by the first brush 31 are peeled off from the film substrate 10.

[0026] It is preferable that the blower 33 blows gas onto the film substrate 10 after it has come into contact with the first brush 31. To this end, the blower 33 is disposed downstream of the first brush 31 in the transport direction and upstream of the position where another member (e.g., the second brush 35) comes into contact with the front surface of the film substrate 10. This allows the remaining deposits to be removed before the gap between the film substrate 10 and the remaining deposits is pressed against the other member and closed again. However, if blowing before the gap closes is possible, the blower 33 does not need to blow gas onto the film substrate 10 immediately after it has come into contact with the first brush 31. For example, the blower 33 may blow gas onto the film substrate 10 that has been transported a predetermined distance after contacting the first brush 31.

[0027] The blower 33 may be an ion blower (for example, an ionizer with a built-in air blower) that blows ionized air toward the front surface of the film substrate 10. This neutralizes the peeled-off deposits and prevents the deposits from adhering to the first brush 31 or the film substrate 10. Furthermore, a plurality of blowers 33 may be provided. For example, an additional blower 33 may be provided facing the opposite surface of the film substrate 10. This blower 33 blows gas toward the opposite surface of the film substrate 10 to peel off the deposits that have re-adhered to the opposite surface.

[0028] The removal device 100 further includes a dust collection unit 40 as an example of a collection means for collecting the peeled-off deposits. For example, the dust collection unit 40 includes a suction device as an example of a suction means for sucking the peeled-off deposits and a dust collection hood connected to the suction device. The peeled-off deposits are sucked into the suction device through a connection port in the dust collection hood and collected. Alternatively, the suction device may be an electrostatic suction device that charges and attracts the peeled-off deposits. Furthermore, the suction device may be a magnetic suction device that magnetizes and attracts the peeled-off deposits. For example, the tip opening of the dust collection hood faces the contact position where the film substrate 10 and the roll-shaped member (e.g., the first brush 31) come into contact. This allows for effective collection of the peeled-off deposits. The dust collection unit 40 may also include multiple suction devices and dust collection hoods.

[0029] With this removal device 100, the bristles of the first brush 31 come into contact with the front side of the film substrate 10, on which the deposits are attached, as it is being transported. The bristles then peel the deposits off the film substrate 10. Furthermore, the blower 33 blows air into the gap between the film substrate 10 and the remaining deposits that were not removed by the first brush 31. This peels off the remaining deposits from the film substrate 10. This makes it possible to more efficiently peel off the deposits from the film substrate 10 in a short period of time, and also more reliably peel off the remaining deposits. Furthermore, the peeled off deposits are sucked and collected by the dust collection unit 40, so that the peeled off deposits can be removed continuously from the peeling process.

[0030] The removal device 100 also includes a second brush 35 in the peeling unit 30. This second brush 35 comes into contact with the film substrate 10 being transported to peel off deposits from the film substrate 10. The second brush 35 is softer than the first brush 31. For example, the Shore D hardness of the bristles of the second brush 35 is smaller than that of the bristles of the first brush 31. The soft second brush 35 peels off deposits from the film substrate 10 that remain after peeling by the first brush 31 and the blower 33. This makes it possible to more reliably peel off deposits from the film substrate 10 and remove the peeled off deposits.

[0031] The second brush 35 may be a roll brush. In this case, the removal device 100 includes a drive device that rotates the roll brush, which is a drive device included in the peeling unit 30. The second brush 35 may also be a cup brush. In this case, the removal device 100 includes a traverse mechanism that winds up the film substrate 10. Furthermore, a plurality of second brushes 35 may be provided. For example, a second brush 35 that contacts the opposite surface of the film substrate 10 may be provided.

[0032] The peeling unit 30 also has a blower 37 that blows gas onto the film substrate 10 after it has come into contact with the second brush 35. The peeling unit 30 also has an opposing roller 36 that faces the second brush 35 with the film substrate 10 sandwiched between them. The peeling unit 30 also has a dust collection unit 40. The opposing roller 36 has the same configuration as the opposing roller 32, and the blower 37 has the same configuration as the blower 33, so their description will be omitted. The first brush 31, the opposing roller 32, the blower 33, the second brush 35, the opposing roller 36, the blower 37, and the dust collection unit 40 are housed in a housing that prevents the peeled-off deposits from scattering.

[0033] The removal device 100 includes a wiping unit 50 as an example of a wiping means for wiping off deposits from at least one of the front and opposite sides of the film substrate 10. The removal device 100 also includes a roller pair 51 included in the wiping unit 50. This roller pair 51 is composed of two rollers, each having a fiber layer. One roller contacts the front side of the film substrate 10 as it is being transported. The other roller contacts the opposite side of the film substrate 10 as it is being transported. As an example, the fiber layer of each roller is a felt layer that is the surface layer of the roller. Alternatively, the surface layer of each roller may be a woven fabric layer, a knitted fabric layer, or a nonwoven fabric layer. Such a roller pair 51 can remove remaining deposits, redeposited deposits, and debris from the film substrate 10.

[0034] The wiping unit 50 may have multiple roller pairs 51. The wiping unit 50 also has a cleaning brush 52 and a dust collection unit 40. For example, the cleaning brush 52 is a roll-shaped brush that is driven to rotate. The cleaning brush 52 comes into contact with one of the rollers of the roller pair 51 to peel off and remove any deposits adhering to that roller. Alternatively, the wiping unit 50 may have a cleaning device that immerses each roller of the roller pair 51 in a cleaning tank to clean it.

[0035] 1, the cleaning brush 52 and the dust collection unit 40 are provided on the front side of the film substrate 10 (i.e., the lower side in FIG. 1). However, the cleaning brush 52 and the dust collection unit 40 may also be provided on the opposite side of the film substrate 10 (i.e., the upper side in FIG. 1). In this specification, the upper side corresponds to the upward direction in the direction of gravity, and the lower side corresponds to the downward direction in the direction of gravity.

[0036] Furthermore, the removal device 100 includes a supplying means included in the wiping unit 50. This supplying means supplies cleaning liquid to the film substrate 10 after contact with the first brush 31. For example, the supplying means is a spraying device 55 that sprays a mist of cleaning liquid onto the film substrate 10. Specifically, the spraying device 55 sprays the mist of cleaning liquid through a spray nozzle extending in the width direction of the film substrate 10. For example, the spraying device 55 sprays a quantity of cleaning liquid onto the film substrate 10 that does not drip from the film substrate 10.

[0037] As an example, the cleaning liquid is tap water, treated water obtained by removing impurities from tap water, or pure water. However, the cleaning liquid may also be a liquid that has the effect of dissolving deposits. Alternatively, the supply means may be a discharge device that discharges the cleaning liquid from a nozzle. Note that multiple supply means may be provided. For example, an additional supply means may be provided on the opposite side of the film substrate 10 (i.e., the upper side in FIG. 1).

[0038] The removal device 100 also includes a wiping roller 56 in the wiping unit 50. This wiping roller 56 wipes away the cleaning liquid from the film substrate 10. For example, the wiping roller 56 comes into contact with the film substrate 10 as it is being transported to wipe away the cleaning liquid. Although the wiping roller 56 is a drive roller, it may also be a driven roller that rotates as the film substrate 10 is transported. For example, the surface layer of the wiping roller 56 is a fiber layer made of cotton. Alternatively, the wiping roller 56 may be an absorbent roller made of a porous material such as a sponge. In the example shown in FIG. 1, two wiping rollers 56 contact both the front and rear surfaces of the film substrate 10. However, the wiping roller 56 may also be provided only on the front side of the film substrate 10.

[0039] The spray device 55 and the wiping roller 56 may be disposed downstream of the first brush 31 in the transport direction. This allows the cleaning liquid to be supplied to the film substrate 10 after contact with the first brush 31, and the cleaning liquid to be wiped away. For example, the spray device 55 and the wiping roller 56 may be disposed between the first brush 31 and the second brush 35. Alternatively, the wiper roller 56 may be disposed between the second brush 35 and the roller pair 51.

[0040] In the example shown in FIG. 1 , a spray device 55 and a wiping roller 56 are disposed downstream of the roller pair 51 in the conveyance direction. This allows the film substrate 10 to be washed and the cleaning liquid to be wiped away as a finishing touch to removing the deposits. As a result, the film substrate 10 does not get wet, making it easier to reuse as recycled material. Alternatively, the removal device 100 may include a drying device for drying the film substrate 10 instead of or in addition to the wiping roller 56. The roller pair 51, cleaning brush 52, dust collection unit 40, spray device 55, and wiping roller 56 are housed in a housing that prevents the peeled deposits from scattering.

[0041] The removal device 100 further includes a cutter 60 that cuts the film substrate 10 from which the cleaning liquid has been wiped. The cutter 60 cuts the film substrate 10 to produce a recycled material in the form of many small pieces. The delivery unit 20 further includes a delivery roller pair 21 downstream of the wiping unit 50 in the transport direction. The delivery unit 20 then transports the film substrate 10 from which the cleaning liquid has been wiped to the cutter 60.

[0042] Alternatively, the removing device 100 may include a winding machine for the film substrate 10 instead of the cutter 60. Furthermore, the removing device 100 may include a melting machine for melting the film substrate 10 instead of or in addition to the cutter 60. Furthermore, the removing device 100 may include a crusher for finely crushing the film substrate 10 instead of or in addition to the cutter 60. In this case, the removing device 100 may further include a compressor for compressing and solidifying the crushed film substrate 10.

[0043] [Adhesion removal process] The removal process for removing deposits from the film substrate 10 will be described with reference to the flowchart in FIG. 2. First, the delivery unit 20 transports the film substrate 10 to the peeling unit 30. Then, in the peeling unit 30, the first brush 31 peels off the deposits from the film substrate 10 (S101). Also, in the peeling unit 30, the blower 33 blows air onto the film substrate 10 (S102). This causes air to enter the gap between the deposits that the first brush 31 has come into contact with and the film substrate 10. Therefore, the deposits that remain and have not been peeled off by the first brush 31 are peeled off from the film substrate 10.

[0044] Next, the suction device of the dust collection unit 40 sucks and collects the peeled-off deposits (S103). This peels off and removes the deposits from the film substrate 10. Furthermore, in the peeling unit 30, the second brush 35 peels off the remaining deposits from the film substrate 10 (S104). Thereafter, the delivery unit 20 transports the film substrate 10 to the wiping unit 50. Then, in the wiping unit 50, the roller pair 51 peels off the remaining deposits from the film substrate 10 (S105).

[0045] Furthermore, in the wiping unit 50, the spray device 55 sprays cleaning liquid onto the film substrate 10 (S106). Next, the wiping roller 56 wipes the cleaning liquid off the film substrate 10 (S107). Thereafter, the delivery unit 20 transports the film substrate 10 from which the cleaning liquid has been wiped off to the cutter 60. The cutter 60 then cuts the film substrate 10 to produce recycled material (S108).

[0046] According to the removal device 100 of the first embodiment described above, the remaining deposits that were not removed by the first brush 31 are removed from the film substrate 10. This allows the deposits to be removed from the film substrate 10 more efficiently in a short time and more reliably. Furthermore, the removed deposits are sucked and collected by the dust collection unit 40, so the removed deposits can be removed continuously from the removal process.

[0047] In the first embodiment, the first brush 31 is provided on the lower side of the film substrate 10. Therefore, the front surface of the film substrate 10 faces downward. However, the first brush 31 may be provided on the upper side of the film substrate 10. The film substrate 10 may be transported in a direction parallel to or along the direction of gravity. In this case, each brush is disposed to the side of the transport path so as to come into contact with the front surface of the film substrate 10 on which the deposits are attached.

[0048] The removal device 100 further includes a control device that controls the entire removal device 100. This control device controls the rotation speed of rotating members such as the first brush 31 and the second brush 35. The control device also controls the transport speed of the film substrate 10 by the delivery unit 20. The wiping unit 50 may be omitted. In this case, the film substrate 10 may be wound up after removing the deposits, and then washed and dried in a separate device.

[0049] [Second embodiment] A second embodiment will be described with reference to Fig. 3 and Fig. 4. Fig. 3 is a configuration diagram of a removal device 200 according to the second embodiment. Fig. 3 schematically shows the devices and members that make up the removal device 200. Fig. 4 is a cross-sectional view of a dust collection unit 240 according to the second embodiment. In Fig. 4, a part of a dust collection hood 241 that is hidden by a first brush 231 and the like is indicated by a dotted line.

[0050] The second embodiment differs from the first embodiment in the configuration downstream of the first brush 231 in the transport direction. For example, the second embodiment differs from the first embodiment in that the removal device 200 does not include the second brush 35. However, the removal device 200 may include the second brush 35. Similarly, the removal device 200 may include the devices and components described in the first embodiment.

[0051] In the description of the second embodiment, differences from the first embodiment will be described, and the same reference numerals will be used for the components already described, and their description will be omitted. Unless otherwise specified, the components with the same reference numerals perform substantially the same operations and functions, and have substantially the same effects.

[0052] The removal device 200 shown in FIG. 3 includes a peeling unit 230 as an example of a removal unit that peels off deposits from the film substrate 10. The removal device 200 also includes a first brush 231 included in the peeling unit 230. This first brush 231 comes into contact with the film substrate 10 being transported in order to peel off deposits from the film substrate 10. The first brush 231 in the second embodiment is also a hard brush made of hard resin. In the second embodiment, the first brush 231 is provided on the upper side of the film substrate 10. Therefore, the front surface of the film substrate 10 faces upward. However, the first brush 231 may also be provided on the lower side of the film substrate 10.

[0053] Furthermore, the peeling unit 230 has an opposing roller 232 that faces the first brush 231 with the film substrate 10 sandwiched therebetween. In the second embodiment, the opposing roller 232 is provided below the film substrate 10. Also in the second embodiment, the first brush 231 is a roll brush, but the first brush 231 may be a cup brush. The removal device 200 is further provided with a blower 233 that the peeling unit 230 has. This blower 233 is also an ion blower. This neutralizes the peeled deposits and prevents the deposits from adhering to the first brush 231 or the film substrate 10.

[0054] 4, in the second embodiment, an outlet 233A of a blower 233 is located inside a dust collection unit 240. Specifically, a dust collection hood 241 of the dust collection unit 240 surrounds the periphery of the outlet 233A. Furthermore, a tip opening of the dust collection hood 241 surrounds at least a portion of the first brush 231. Alternatively, the dust collection hood 241 may surround the entire first brush 231.

[0055] The air blown out from the outlet 233A in the direction indicated by arrow A is blown toward the front of the film substrate 10. This allows the air to enter the gap created by the first brush 231 between the film substrate 10 and the deposits. As a result, any deposits that remain unremoved by the first brush 231 are removed from the film substrate 10. Here, the dust collection hood 241 surrounds at least a portion of the first brush 231. This prevents the deposits from scattering, and the deposits are sucked in the direction indicated by arrow B. The deposits are then collected by a suction device connected to the connection port 242.

[0056] The removal device 200 also includes a cover member 245 located on the opposite side of the film substrate 10 from the first brush 231. As an example, the cover member 245 extends in both the upstream and downstream directions of the opposing roller 232 in the conveyance direction, excluding the contact area between the first brush 231 and the opposing roller 232. The cover member 245 also extends across the entire width of the film substrate 10 in the width direction. This cover member 245 can prevent peeled off material from adhering to the opposing roller 232. The cover member 245 can also prevent peeled off material from scattering. The cover member 245 may be a non-electrostatic member. Being non-electrostatic can prevent peeled off material from adhering to the cover member 245.

[0057] Returning to FIG. 3 , the removal device 200 includes a removal unit 70 that removes a release layer, which is an example of a coating layer that coats the film substrate 10. The removal unit 70 has a polishing member 71 that comes into contact with the film substrate 10 to remove the release layer. As an example, the polishing member 71 is a cloth buff or a nonwoven fabric buff that rotates in contact with the film substrate 10. The removal unit 70 also has an opposing roller 72 that faces the polishing member 71 with the film substrate 10 sandwiched between them.

[0058] Furthermore, the removal unit 70 has an ion blower 73 that blows ionized air onto the front surface of the film substrate 10. The first brush 231, the opposing roller 232, the blower 233, and the dust collection unit 240 are housed in a housing that prevents the peeled off deposits from scattering. The polishing member 71, the opposing roller 72, and the ion blower 73 are also housed in a housing that prevents the coating layer from scattering.

[0059] The removal device 200 includes a pair of downstream rollers 256 located downstream of the removal unit 70. The removal device 200 also includes an ion blower 257 that blows ionized air onto the front surface of the film substrate 10. Each downstream roller 256 then wipes off any remaining deposits on the film substrate 10. For example, the downstream rollers 256 come into contact with the film substrate 10 as it is being transported to wipe off the deposits. Although the downstream rollers 256 are drive rollers, they may also be driven rollers that rotate as the film substrate 10 is transported. As an example, the surface layer of the downstream rollers 256 is a fiber layer made of cotton. In the example shown in FIG. 1, the two downstream rollers 256 are in contact with both the front and rear surfaces of the film substrate 10. However, the downstream rollers 256 may also be provided only on the front side of the film substrate 10.

[0060] The removal device 200 according to the second embodiment described above also removes the remaining deposits that were not removed by the first brush 231 from the film substrate 10. This allows the deposits to be removed from the film substrate 10 more efficiently in a short time and more reliably. Furthermore, the removed deposits are sucked and collected by the dust collection unit 240, so the removed deposits can be removed continuously from the removal process.

[0061] [Transformation] The peeling units 330A and 330B according to the modified embodiment will be described with reference to FIGS. 5 and 6. FIGS. 5 and 6 are explanatory diagrams of the peeling units 330A and 330B according to the modified embodiment. The devices and components constituting the peeling units 330A and 330B are schematically shown in FIGS. 5 and 6. In the description of the modified embodiment, differences from the second embodiment will be described, and components already described will be given the same reference numerals and will not be described again. Unless otherwise specified, components with the same reference numerals perform substantially the same operations and functions, and their effects are also substantially the same.

[0062] The removal device 200 according to the modified embodiment includes contact members provided in the peeling units 330A and 330B. These contact members contact the film substrate 10 as it is being transported. The contact member provided in the peeling unit 330A shown in FIG. 5 is a scraper SP extending in the width direction of the film substrate 10, which is perpendicular to the transport direction of the film substrate 10. The scraper SP contacts the front surface of the film substrate 10 upstream of the first brush 231 in the transport direction. This scraper SP can physically remove the deposits from the film substrate 10 and can also create a gap between the deposits and the film substrate 10. Alternatively, the scraper SP may be provided downstream of the first brush 231 in the transport direction. In this case, multiple scrapers SP may be provided.

[0063] Fig. 6 shows a contact member according to another modified embodiment. The contact member of the peeling unit 330B shown in Fig. 6 is a roller 332 having protrusions 332A extending in the width direction perpendicular to the conveyance direction of the film substrate 10. The roller 332 is in contact with the opposite surface of the film substrate 10. The roller 332 faces the first brush 231 across the film substrate 10. The protrusions 332A are formed at equal intervals and protrude outward from the roller 332.

[0064] Then, in the portion where the protrusion 332A contacts the film substrate 10, the film substrate 10 is deformed so as to bend. As a result, the film substrate 10 is pressed toward the first brush 231. This causes the brush bristles of the first brush 231 to come into strong contact with the film substrate 10. As a result, deposits are easily peeled off in the bent portion of the film substrate 10. Furthermore, gaps are easily formed between the deposits and the film substrate 10 in the bent portion.

[0065] [Third embodiment] A third embodiment will be described with reference to Fig. 7. Fig. 7 is a configuration diagram of a removal device 400 according to the third embodiment. Fig. 7 also shows a schematic representation of the devices and members constituting the removal device 400. The third embodiment differs from the first embodiment in the configurations of a peeling unit 430 and a wiping unit 450.

[0066] In the description of the third embodiment, differences from the first embodiment will be described, and components already described will be given the same reference numerals and their description will be omitted. Unless otherwise specified, components with the same reference numerals perform substantially the same operations and functions, and their effects are also substantially the same. Furthermore, the removal device 400 may include each device and member described in the first embodiment.

[0067] The removing device 400 includes a feed unit 420, which is an example of a conveying means for conveying the film substrate 10. The feed unit 420 holds a substrate roll 411 made up of wound film substrate 10. The feed unit 420 also includes a pair of feed rollers 421 that sandwich and feed the film substrate 10.

[0068] Here, an irregularly shaped hole 412 is formed around the central shaft 410C of the base roll 411. As an example, the hole 412 is formed by winding the film substrate 10 around a core and then removing the core from the base roll 411. If a core is not inserted into the hole 412 of the base roll 411, the hole 412 will bend even if the central shaft 410C is inserted. When the base roll 411 is rotated together with the central shaft 410C in this state, the contact position between the inner circumferential surface of the hole 412 and the central shaft 410C fluctuates. For example, when the base roll 411 is rotated, the central shaft 410C sometimes contacts the inner circumferential surface at one end of the hole 412 and sometimes contacts the inner circumferential surface at the other end of the hole 412.

[0069] As a result, the base roll 411 rotates while moving up and down. Therefore, as the base roll 411 rotates, displacement of the center shaft 410C and the base roll 411 occurs during transport of the film substrate 10. That is, as the base roll 411 rotates, periodic positional fluctuations of the base roll 411 occur. This increases the load on the center shaft 410C that supports the base roll 411. Furthermore, as the base roll 411 moves, fluctuations occur in the transport speed of the film substrate 10 fed from the base roll 411. When the transport speed fluctuates, the contact area between the film substrate 10 and the first brush 431 and the frictional force at the time of contact become non-uniform. As a result, the degree of removal of the deposits may become non-uniform.

[0070] Therefore, the delivery unit 420 has an insertion member 413 that is inserted into the hole 412. In the example of FIG. 7, the delivery unit 420 has two cylindrical insertion members 413. This prevents the hole 412 from bending. That is, the hole 412 is widened in the left-right direction in FIG. 7 by the insertion members 413. Therefore, tension is applied to the hole 412 by the insertion members 413 and the central shaft 410C. This prevents the displacement of the central shaft 410C relative to the hole 412, thereby preventing the displacement of the central shaft 410C and the substrate roll 411. Furthermore, fluctuations in the transport speed of the film substrate 10 can also be suppressed.

[0071] The insertion members 413 are configured so that the distance therebetween with respect to the central axis 410C can be changed. For example, after a pair of insertion members 413 are inserted, one insertion member 413 can be separated from the other insertion member 413 until they contact both ends of the hole 412. Thereafter, the pair of insertion members 413 can be fixed with respect to the central axis 410C. For example, the pair of insertion members 413 are fixed by being attached to a fixing frame fixed to the central axis 410C.

[0072] As a result, the pair of insertion members 413 and the central shaft 410C rotate integrally. In the example of FIG. 7, when the base roll 411 rotates 90 degrees in the direction of rotation indicated by arrow C, the orientation of the holes 412 extending in the left-right direction changes to an orientation extending in the up-down direction. Note that in FIG. 7, the holes 412 rotated by 90 degrees are indicated by dotted lines. Furthermore, the positions of the pair of insertion members 413 and the central shaft 410C, which were aligned in the left-right direction in FIG. 7, also change to aligned in the up-down direction. In this way, the insertion members 413 and the central shaft 410C rotate together with the holes 412 while maintaining their alignment order.

[0073] Although the diameter of the insert member 413 in FIG. 7 is shorter than the central axis 410C, it may be longer than the central axis 410C. Furthermore, as long as the film substrate 10 is stretched so as to suppress deflection of the hole 412, the position, number, and shape of the insert members 413 can be set arbitrarily. For example, the central axis 410C and one insert member 413 may be inserted into the hole 412. Furthermore, the number of insert members 413 may be three or more. Furthermore, the multiple insert members 413 do not have to be arranged in a line. For example, the multiple insert members 413 may be arranged so as to be located at the vertices of a polygon. As an example, three insert members 413 may be arranged so as to be located at the vertices of a triangle. Furthermore, the insert member 413 may be one or more plate members having an elliptical cross-sectional shape, or may have another cross-sectional shape, such as a triangle or a rectangle. Furthermore, the insert member 413 may be a member to which a rotatable roller is attached.

[0074] Alternatively, if the frictional resistance between the insertion member 413 and the central shaft 410C and the film substrate 10 is small, the substrate roll 411 may rotate so as to slide relative to the insertion member 413 and the central shaft 410C. In this case, the insertion member 413 and the central shaft 410C do not rotate.

[0075] The feed unit 420 has a pair of feed rollers 421 that sandwich and feed the film substrate 10. Each roller of the pair of feed rollers 421 is a drive roller that is rotationally driven by a drive device. This makes it possible to suppress fluctuations in the conveying speed of the film substrate 10 even when the substrate roll 411 vibrates. As an example, each roller of the pair of feed rollers 421 is controlled to rotate at the same speed. Furthermore, each roller is controlled to rotate in accordance with the rotation speed of the substrate roll 411.

[0076] The feed unit 420 also has a guide roller 423 that guides the film substrate 10 pulled out from the substrate roll 411 to the pair of feed rollers 421. The guide roller 423 is a driven roller that rotates in accordance with the movement of the film substrate 10. However, the guide roller 423 may also be a drive roller.

[0077] The removal device 400 also includes a peeling unit 430 as an example of a removal means for peeling off the deposits from the film substrate 10. The removal device 400 also includes a first brush 431 included in the peeling unit 430. The peeling unit 430 also includes an opposing roller 432 that faces the first brush 431 with the film substrate 10 sandwiched between them. The first brush 431 comes into contact with the film substrate 10 being transported in order to peel off the deposits from the film substrate 10. For example, the first brush 431 is a roll brush that rotates while in contact with the film substrate 10. As a result, the numerous brush bristles included in the first brush 431 physically peel off the deposits from the film substrate 10.

[0078] However, simply rotating the roll brush that contacts the transported film substrate 10 may result in some of the adhering material not being removed. Therefore, the peeling unit 430 is provided with a moving means 439 that moves the first brush 431 back and forth in a direction that intersects with the transport direction D of the film substrate 10. In the example of FIG. 7, the transport direction D indicated by the arrow is a direction that proceeds from left to right. However, the transport direction D may be other directions, such as upward, leftward, downward, or diagonal.

[0079] For example, the moving means 439 is a traverse mechanism that reciprocates the holding mechanism of the first brush 431 in a direction perpendicular to the conveyance direction D. As a result, the first brush 431 held by the holding mechanism also reciprocates together with the holding mechanism. That is, the first brush 431 moves in a direction away from the initial position to a limit position, and then returns from the limit position to the initial position. For example, the initial position is near one side edge of the film substrate 10, and the limit position is near the other side edge of the film substrate 10. This reciprocating movement allows the film substrate 10 to be rubbed in a direction intersecting the conveyance direction D, thereby preventing the adhesions from being removed. Alternatively, the moving means 439 may reciprocate the first brush 431 itself.

[0080] As an example, the distance that first brush 431 moves in one direction is 3 mm or more and 9 mm or less. Therefore, the distance of one reciprocating movement is twice the distance of the movement in one direction. However, the distance of one reciprocating movement may be shorter than 3 mm or longer than 9 mm. Furthermore, moving means 439 moves first brush 431 back and forth multiple times while first brush 431 makes one rotation.

[0081] The first brush 431 is disposed on the lower side so as to come into contact with the front surface of the film substrate 10. However, if there is an attachment on the opposite surface of the film substrate 10, the reciprocating first brush 431 may be disposed on the upper side of the film substrate 10. Furthermore, multiple reciprocating first brushes 431 may be disposed on both sides of the film substrate 10 so as to come into contact with both surfaces of the film substrate 10. A blower 33 that blows gas onto the film substrate 10 may also be disposed.

[0082] The first brush 431 removes the deposits from the film substrate 10. However, there is a possibility that the removed deposits may re-adhere to the film substrate 10 due to static electricity or the like. Therefore, the removal device 400 is provided with a wiping unit 450 as an example of a wiping means that wipes off the deposits from at least one of the front and opposite surfaces of the film substrate 10. The wiping unit 450 is provided with at least one of felt roller 451A and felt roller 451B as a roller that comes into contact with at least one of the front and opposite surfaces of the film substrate 10 being transported. As a result, even if the deposits re-adhere to the front or opposite surface of the film substrate 10, the deposits can be wiped off by the felt roller 451A and the felt roller 451B.

[0083] The surface layers of felt rollers 451A and 451B are felt layers, which are fiber layers. Alternatively, the surface layers of the rollers of wiping unit 450 may be woven, knitted, or nonwoven fabric layers. Felt rollers 451A and 451B are arranged on the lower side so as to contact the front surface of film substrate 10. However, felt rollers 451A and 451B may also be arranged on the upper side so as to contact the opposite surface of film substrate 10. Wiping unit 450 may also have an opposing roller that faces at least one of felt roller 451A and felt roller 451B.

[0084] The wiping unit 450 has a collection roller 452 that comes into contact with the felt roller 451B and collects the deposits adhering to the felt roller 451B. This allows the collection roller 452 to remove the deposits that have accumulated on the felt roller 451B. As an example, the surface layer of the collection roller 452 is a felt layer, which is a fiber layer. Alternatively, the surface layer of the collection roller 452 may be a woven fabric layer, a knitted fabric layer, or a nonwoven fabric layer. Furthermore, the collection roller 452 has the same diameter as the felt roller 451B, but may also have a diameter that is longer or shorter than that of the felt roller 451B.

[0085] Wiping unit 450 also has a plurality of rollers 456 that guide film substrate 10 as it is being transported. Film substrate 10 guided by rollers 456 is then pushed up by felt roller 451A or 451B. This brings film substrate 10 into close contact with felt roller 451A and felt roller 451B, improving the efficiency of wiping off deposits.

[0086] Furthermore, wiping unit 450 has a supply unit 455 that supplies liquid to collection roller 452. This allows wet collection roller 452 to come into contact with felt roller 451B, improving the efficiency of collection of deposits accumulated on felt roller 451B. For example, supply unit 455 has a liquid nozzle CN, a liquid pump CP, and a liquid tank CT. Supply unit 455 sprays liquid onto at least a portion of collection roller 452. As an example, the liquid is tap water, treated water obtained by removing impurities from tap water, or pure water.

[0087] For example, the supply unit 455 uses a liquid pump CP to send liquid from a liquid tank CT to a liquid nozzle CN. The supply unit 455 then sprays the sent liquid from the liquid nozzle CN onto a portion of the surface of the collection roller 452 in the form of a mist. The liquid nozzle CN extends along the direction of the rotation axis of the collection roller 452 and has a width sufficient to wet a predetermined area. Alternatively, the liquid nozzle CN may be configured to move along the direction of the rotation axis of the collection roller 452 to wet the predetermined area. In this case, the supply unit 455 further includes a movement device for the liquid nozzle CN. Alternatively, the supply unit 455 may eject liquid from the liquid nozzle CN. The supply unit 455 may also supply liquid to the inside of the collection roller 452. In this case, the supplied liquid seeps out from the inside of the collection roller 452 onto the surface.

[0088] Felt roller 451A, felt roller 451B, and collection roller 452 are configured to be rotatable. Supply unit 455 has a drive device that rotates each roller. Alternatively, at least one of felt roller 451A, felt roller 451B, and collection roller 452 may be a driven roller. Furthermore, at least one of felt roller 451A, felt roller 451B, and collection roller 452 may be a fixed roller that does not rotate.

[0089] The wiping unit 450 also has a drying unit 457. For example, the drying unit 457 is a heat blower that blows hot air onto the film substrate 10. The drying unit 457 is disposed below the film substrate 10 so as to blow hot air onto the front surface of the film substrate 10. Alternatively, the drying units 457 may be disposed on both sides of the film substrate 10 so as to blow hot air onto both surfaces of the film substrate 10. The wiping unit 450 may also have a wiping roller 56 instead of or in addition to the drying unit 457. The drying unit 457 may also blow cold air or room temperature air onto the film substrate 10. The drying unit 457 may also be an irradiation device that irradiates the film substrate 10 with infrared rays, far infrared rays, or the like.

[0090] Furthermore, wiping unit 450 has dust collection unit 440A and dust collection unit 440B. For example, dust collection unit 440A and dust collection unit 440B have suction devices as an example of suction means that suck up deposits adhering to felt roller 451A or collection roller 452. Dust collection unit 440A and dust collection unit 440B also have dust collection nozzles connected to the suction devices. The tip openings of the dust collection nozzles face felt roller 451A or collection roller 452. The dust collection nozzles reciprocate along the rotation axis of felt roller 451A or collection roller 452, sucking up deposits as they move. Alternatively, the suction means may be an electrostatic suction device or a magnetic suction device.

[0091] The removal device 400 further includes a dust collection system 480. The dust collection system 480 is connected to the housings of the peeling unit 430 and the wiping unit 450. The dust collection system 480 sucks the deposits peeled off from the film substrate 10 from the peeling unit 430 and the wiping unit 450.

[0092] The delivery unit 420 of the removal device 400 has a delivery roller pair 421 between the cutter 60 and the wiping unit 450. The delivery unit 420 transports the film substrate 10 dried by the drying unit 457 to the cutter 60 by the delivery roller pair 421.

[0093] [Recovery of reattached deposits] Next, the collection of the re-adhered deposits will be described with reference to Fig. 7. Felt roller 451A is in contact with film substrate 10 being transported without rotating. Any deposits that have re-adhered to film substrate 10 are collected by felt roller 451A. The deposits collected by felt roller 451A are then sucked and collected by dust collection unit 440A.

[0094] Furthermore, when deposits accumulate, felt roller 451A rotates by a predetermined angle until the contact area with film substrate 10 faces the dust collection nozzle of dust collection unit 440A. For example, the predetermined angle is 120 degrees, but it can be set arbitrarily depending on the position of the dust collection nozzle. This causes the contact area with film substrate 10 to face the dust collection nozzle of dust collection unit 440A. Dust collection unit 440A then sucks up the deposits while moving the dust collection nozzle in a direction along the rotation axis of felt roller 451A. Note that dust collection unit 440A may move the dust collection nozzle in only one direction, or may move the dust collection nozzle back and forth.

[0095] As felt roller 451A rotates, a new area free of deposits comes into contact with film substrate 10. Then, when deposits accumulate in the new area, felt roller 451A rotates again. In this way, the collection of deposits by felt roller 451A and the suction of deposits by dust collection unit 440A are repeated.

[0096] Furthermore, any adhering matter that is not collected by felt roller 451A is collected by felt roller 451B. Specifically, felt roller 451B is in contact with film substrate 10 while rotating, and any adhering matter that is not collected by felt roller 451A is collected by felt roller 451B.

[0097] Thereafter, the deposits adhering to felt roller 451B are collected by collection roller 452. Furthermore, the deposits adhering to and accumulating on collection roller 452 are sucked and collected by dust collection unit 440B. For example, collection roller 452 is in contact with felt roller 451B while not rotating. Then, when deposits accumulate, collection roller 452 rotates a predetermined angle until the contact area with felt roller 451B faces the dust collection nozzle of dust collection unit 440B. For example, the predetermined angle is 90 degrees, but it can be set arbitrarily depending on the position of the dust collection nozzle. Then, dust collection unit 440B sucks the deposits while moving the dust collection nozzle in a direction along the rotation axis of collection roller 452. Note that dust collection unit 440A may move the dust collection nozzle in only one direction, or may move the dust collection nozzle back and forth.

[0098] As collection roller 452 rotates, a new area free of adhering matter comes into contact with felt roller 451B. Then, when adhering matter accumulates in the new area, collection roller 452 rotates again. In this way, collection of adhering matter by collection roller 452 and suction of adhering matter by dust collection unit 440B are repeated.

[0099] Furthermore, the supply unit 455 supplies liquid to the collection roller 452. For example, the supply unit 455 sprays liquid onto the collection roller 452 at a predetermined timing or constantly. As an example, the predetermined spray timing is the timing just before the collection roller 452 rotates. In other words, the collection roller 452 rotates after the supply unit 455 supplies the liquid. At this time, the collection roller 452 rotates so that the area facing the liquid nozzle CN of the supply unit 455 faces the felt roller 451B. Furthermore, the supply unit 455 sprays liquid onto an area extending in a direction parallel to or along the extension direction of the collection roller 452. Alternatively, the supply unit 455 may spray liquid while moving the liquid nozzle CN in a direction along the rotation axis of the collection roller 452.

[0100] Felt roller 451A and collection roller 452 rotate at predetermined time intervals, but may also rotate constantly. Felt roller 451A and collection roller 452 may also rotate in response to human operation. The size of the area to which supply unit 455 supplies liquid may differ from the size of the area from which the dust collection nozzle of dust collection unit 440B collects deposits. For example, the area to which liquid is supplied may be larger than the area from which the dust collection nozzle of dust collection unit 440B collects deposits.

[0101] The removal device 400 according to the third embodiment described above also wipes off any remaining deposits that have not been removed by the first brush 431 from the film substrate 10. This allows the deposits to be removed from the film substrate 10 more efficiently and in a shorter time, and more reliably. Furthermore, the removed deposits are collected by the wiping unit 450, so the removed deposits can be removed continuously from the removal process.

[0102] The removal device 400 further includes a control device that controls the entire removal device 400. This control device controls the rotation timing of rotating members such as the felt roller 451A, the felt roller 451B, and the recovery roller 452. The control device also controls the transport speed of the film substrate 10 by the delivery unit 420. The control device also controls the reciprocating motion of the dust collection unit 440A. The control device also controls the timing of the liquid supply by the supply unit 455.
