Description

  The present invention relates to a hairline processing apparatus and a hairline processing method.

  Conventionally, in order to impart design properties to the surface of a web such as a film, a hairline process is performed on the surface of the web. Hairline processing is performed, for example, by generating a hairline pattern on the surface of the web by rubbing the surface of the web with an abrasive film having abrasive grains fixed on the surface (see Patent Document 1).

  In this hairline processing, when the surface of the web is rubbed with an abrasive film, the web scraped off by the abrasive grains becomes elongated scraps and adheres to the web. This scrap is also called “fluff” because of its elongated shape. When the fluff adheres to the web, the fluff is visually recognized by the user, and the design property is lowered. In addition, the fluff may fall during the conveyance or use of the web, or the fluff may adhere to the other member when contacting the other member, which is not preferable. Therefore, in the hairline processing, it is required to surely remove the fluff generated by friction with the polishing film from the web.

  Conventionally, the removal of fluff from the web has been performed by washing with water. In the film manufacturing apparatus with a hairline pattern of Patent Document 1, a film that is a web is rubbed in a film processing portion while being in contact with a part of a polishing belt having abrasive grains fixed on the surface, and a long hairline on the film surface. A pattern is applied. Thereafter, the film is washed with water in the washing section. A shower is installed in the washing | cleaning part in the position where a film passes, and it is comprised so that it may wash with water from both surfaces of a film. According to the film manufacturing apparatus with a hairline pattern of Patent Document 1, fluff generated by hairline processing is removed by washing with water.

  FIGS. 1-6 is a figure for demonstrating one Embodiment by this invention. Of these, FIG. 1 schematically shows an example of a hairline processing apparatus 10.

  The hairline processing apparatus 10 of this Embodiment is an apparatus which performs the process which provides many linear patterns (hairline) on the surface of the web W, ie, performs a hairline process. The hairline processing is mainly performed in order to impart a hairline pattern to the surface of the web W and improve the design of the web W. The web W as an object on which the hairline processing is performed is not particularly limited, but is a sheet-like or film-like member such as a resin film or a metal foil. In the present embodiment, an example in which a film formed of a resin as the web W is used will be described. In particular, the hairline processing apparatus 10 of the present embodiment is suitable for being used when performing hairline processing on a web W made of a film formed of polyethylene terephthalate (PET) resin.

  The hairline processing apparatus 10 shown in FIG. 1 includes a feeding unit 20 that feeds a web W, a hairline processing unit 30 that performs hairline processing on the web W fed from the feeding unit 20, and hairline processing. A fluff separation unit 40 for separating the fluff C from the broken web W. Furthermore, the hairline processing apparatus 10 winds the fluff removal unit 50 that removes the fluff C separated from the web W by the fluff separation unit 40 from the web W, and the web W from which the fluff C is removed by the fluff removal unit 50. And a winding unit 60. The web W fed from the feeding unit 20 is sequentially processed by the hairline processing unit 30, the fluff separation unit 40, and the fluff removal unit 50, and is finally wound by the winding unit 60.

  In the illustrated example, the web W is formed in a long shape, and the web W is wound into a roll shape to form a raw roll 21. The original fabric roll 21 is attached to the feeding unit 20 by inserting the feeding shaft of the feeding unit 20 through the center thereof. The feeding unit 20 is configured to be capable of feeding out (feeding) the web W from the original fabric roll 21 by, for example, rotation of a feeding shaft to which the original fabric roll 21 is attached. Therefore, the feeding shaft of the feeding unit 20 may be connected to a driving source such as a motor.

  FIG. 2 shows an example of the hairline processing unit 30. The hairline processing unit 30 generates a large number of linear patterns (hairlines) on the surface of the web W by rubbing the surface of the web W fed from the feeding unit 20 with the polishing film 32. That is, the hairline processing unit 30 performs hairline processing on the web W. The polishing film 32 is obtained by dispersing and fixing a large number of abrasive grains on, for example, a resin film. As an abrasive grain, particles, such as aluminum oxide, garnet, silicon carbide, can be used, for example. As an example, the grain size of the abrasive grains can be P400 to P2000 at a grain size defined by JIS R 6010: 2000 (grain size of abrasive for abrasive cloth).

  The hairline processing unit 30 includes an unwinding roll 33 for unwinding the polishing film 32, a winding roll 34 for winding the polishing film 32, a pressing roll 35 for pressing the polishing film 32 against the web W, and a guide roll for guiding the web W 36. The unwinding roll 33 is obtained by winding a long polishing film 32 in a roll shape, and the winding roll 34 is obtained by winding the polishing film 32 after rubbing the surface of the web W in a roll shape. is there. In the illustrated example, in the unwinding roll 33 and the winding roll 34, the polishing film 32 is wound in a roll shape with the surface on which the abrasive grains are dispersed facing outward. The pressing roll 35 is urged toward the guide roll 36, thereby pressing the polishing film 32 unwound from the unwinding roll 33 against the web W supported on the guide roll 36.

  In the example illustrated in FIG. 2, the web W fed from the feeding unit 20 travels from the left side to the right side of the paper surface. In the illustrated example, the unwinding roll 33 is disposed in front of the pressing roll 35 (the right side in FIG. 2) along the traveling direction of the web W, and the winding roll 34 is pressed along the traveling direction of the web W. It is arranged behind 35 (left side in FIG. 2). The polishing film 32 that has been unwound from the unwinding roll 33 is pressed onto the web W by the pressing roll 35, and is then wound around the winding roll 34. At this time, the polishing film 32 unwound from the unwinding roll 33 is located between the pressing roll 35 and the web W from the front side to the rear side in the traveling direction of the web W, that is, opposite to the traveling direction of the web W. Proceed in the direction. That is, between the pressing roll 35 and the guide roll 36, the web W and the polishing film 32 advance in opposite directions while being pressed against each other. As a result, the surface of the polishing film 32 on which the abrasive grains are dispersed rubs the surface of the web W. Specifically, a large number of abrasive grains dispersed and arranged in the polishing film 32 scrapes the surface of the web W from the front side to the rear side along the traveling direction of the web W. As a result, a hairline pattern is formed on the surface of the web W. The hairline pattern is composed of a number of grooves extending along the traveling direction of the web W. In addition, in the hairline process part 30, the fluff C which consists of the part scraped off with the abrasive grain of the polishing film 32 in the web W arises.

  Next, the fuzz separation unit 40 will be described. 3 is a side view showing an example of the fluff separation unit 40, FIG. 4 is a perspective view showing the fluff separation unit 40, and FIG. 5 shows a later-described support roll 42 and blade 46 of the fluff separation unit 40. It is a side view which expands and shows. In particular, FIG. 5 shows an enlarged view of a portion surrounded by a one-dot chain line to which a symbol V in FIG. 3 is attached.

In the example shown in FIGS. 3 to 5, the fluff separation unit 40 includes a support roll 42 and a fluff separation device. The fluff separation device is a device that separates the fluff C on the web W supported along the outer peripheral surface 43 of the support roll 42 from the web W. In this embodiment, the fluff separation device is an outer periphery of the support roll 42. The blade 46 is configured to contact the web W supported along the surface 43.

  The support roll 42 supports the web W along the outer peripheral surface 43 thereof. In particular, the support roll 42 supports the web W such that the surface of the web W opposite to the surface on which the hairline processing is performed by the hairline processing unit 30 faces the outer peripheral surface 43 of the support roll 42. In other words, the web W is supported so that the surface on which the hairline processing is performed in the hairline processing unit 30 faces the side opposite to the support roll 42, that is, the surface on which the hairline processing is performed faces outward. Supported by the roll 42. The support roll 42 has a columnar or cylindrical shape as a whole, and is configured to be rotatable around its central axis. In the illustrated example, the central axis of the support roll 42 extends parallel to a direction orthogonal to the traveling direction of the web W. 3 to 5, the support roll 42 is configured to rotate clockwise.

  In the example shown in FIGS. 3 and 4, the fluff separation unit 40 includes two guide rolls 44 and 44 that change the traveling direction of the web W. One guide roll 44 located on the rear side (the left side in FIGS. 3 and 4) along the traveling direction of the web W has a function of directing the traveling direction of the web W conveyed from the hairline processing unit 30 to the support roll 42. have. Further, the other guide roll 44 located on the front side (the right side in FIGS. 3 and 4) along the traveling direction of the web W changes the traveling direction of the web W conveyed from the support roll 42 to the processing unit ( In this embodiment, it has a function directed to the fluff removing unit 50). Each of the guide rolls 44 and 44 has a columnar shape or a cylindrical shape as a whole, and is configured to be rotatable around each central axis. In the illustrated example, the central axes of the guide rolls 44 and 44 extend in parallel to a direction orthogonal to the traveling direction of the web W. 3 and 4, the guide rolls 44 and 44 are configured to rotate counterclockwise.

  The blade 46 separates the fluff C on the web W from the web W. The blade 46 has a linear blade extending parallel to the central axis of the support roll 42, and this blade abuts on the web W supported along the outer peripheral surface 43 of the support roll 42, The fluff C is separated from the web W. In other words, the blade of the blade 46 is configured to contact the portion of the web W supported along the outer peripheral surface 43 of the support roll 42. The length of the blade 46 along the direction in which the central axis of the support roll 42 extends is longer than the width of the web W.

  As shown in FIG. 5, in a plane orthogonal to the central axis of the support roll 42 (the paper surface of FIGS. 3 and 5), the blade 46 has a tangent to a position where the blade contacts the web W. It is inclined with respect to the direction dt and the normal direction dn to the relevant part. In particular, in the illustrated example, in the plane perpendicular to the central axis of the support roll 42, the blade of the blade 46 has a cutting edge behind the web W in the tangential direction dt and the web W in the normal direction dn. It is inclined with respect to the tangential direction dt and the normal direction dn so as to face the side. The angle θ of the blade 46 with respect to the tangential direction dt of the blade can be set to, for example, 0 degree or more and 90 degrees or less.

  The fluff separation device is not limited to the one having the blade 46 that contacts the web W supported along the outer peripheral surface 43 of the support roll 42 as described above. The fluff separation device may be any device that can separate the fluff C on the web W supported along the outer peripheral surface 43 of the support roll 42 from the web W. The fluff separation device is an abrasive member such as a file, for example. It may be constituted by.

  Next, the fuzz removal unit 50 will be described. FIG. 6 is a diagram illustrating an example of the fuzz removal unit 50.

  The fluff removing unit 50 removes the fluff C separated from the web W by the fluff separating unit 40 and attached to the web W from the web W. In the illustrated example, the fluff removing unit 50 includes an adhesive roll 52 and a guide roll 54 that guides the web W. The adhesive roll 52 has an adhesive layer on its outer peripheral surface 53. The adhesive layer is not particularly limited, and can be a layer made of various materials having adhesiveness. In the illustrated example, the web W is sandwiched between the adhesive roll 52 and the guide roll 54, and the fluff C attached to the web W is attached to the adhesive layer of the adhesive roll 52 and removed from the web W. In addition, it is not restricted to this, The adhesive roll 52 is arrange | positioned instead of the guide roll 54, ie, the two adhesive rolls 52 are arrange | positioned, the web W is clamped by the said 2 adhesive rolls 52, and the fluff C adhering to the web W is attached. May be attached to the adhesive layer of each adhesive roll 52 and removed from the web W. In this case, the fluff C adhering to the front and back surfaces of the web W can be removed.

  The winding unit 60 winds the web W from which the fluff C has been removed by the fluff removing unit 50. In the winding unit 60, a winding roll 61 is formed by the web W wound on a winding shaft attached to the winding unit 60. The winding unit 60 is configured to be able to wind the web W on the winding shaft by rotating the winding shaft. Therefore, the winding shaft is connected to a drive source such as a motor.

  Next, a hairline processing method using the hairline processing apparatus 10 will be described.

[Web feeding process]
First, the web W is fed from the raw roll 21 of the feeding unit 20 toward the hairline processing unit 30. For example, the web W is pulled by the take-up unit 60 by rotating the take-up shaft of the take-up unit 60 with a driving force from a drive source such as a motor, whereby the original roll 21 is rotated. Web W is fed from. However, the present invention is not limited to this, and the web W may be fed from the web roll 21 by rotating the feed shaft to which the web roll 21 is attached by a driving force from a drive source such as a motor. Good.

[Hairline processing process]
Next, hairline processing is performed on the web W fed from the feeding unit 20. In the example shown in FIG. 2, the polishing film 32 unwound from the unwinding roll 33 is pressed onto the web W by the pressing roll 35 and then wound onto the winding roll 34. At this time, the polishing film 32 unwound from the unwinding roll 33 advances in the direction opposite to the traveling direction of the web W between the pressing roll 35 and the web W. That is, between the pressing roll 35 and the guide roll 36, the web W and the polishing film 32 advance in opposite directions while being pressed against each other. Thereby, a large number of abrasive grains dispersed and arranged in the polishing film 32 scrapes the surface of the web W from the front side to the rear side along the traveling direction of the web W. As a result, a hairline pattern is formed on the surface of the web W. The hairline pattern is composed of a number of grooves extending along the traveling direction of the web W.

  At this time, on the surface of the web W, the fluff C which consists of the part scraped off with the abrasive grain of the polishing film 32 arises. Among the many fluffs C generated on the surface of the web W, those that are completely separated from the web W main body and those that are not completely separated from the web W main body, some of which are connected to the web W main body. There are things that become. In particular, among the many fluff C, there is a fluff C that remains connected to the main body of the web W on the rear side along the traveling direction of the web W.

  Conventionally, such fluff has been removed from the web by washing with water or the like. However, in the removal by washing, fluff that is not completely separated from the web body and part of which remains connected to the web body cannot be removed sufficiently.

[Fuzz separation process]
In the hairline processing method of the present embodiment, after the hairline processing step, a fluff separation step of removing the fluff C from the web W on which the hairline processing has been performed is performed. In the fluff separation step, the fluff C on the web W supported along the outer peripheral surface 43 of the support roll 42 is separated from the web W. In the example shown in FIGS. 3 to 5, the web W is supported by the support roll 42 such that the surface of the web W opposite to the surface on which the hairline processing is performed faces the outer peripheral surface 43 of the support roll 42. Is done. In other words, the surface of the web W on which the hairline processing has been performed is supported by the support roll 42 such that the surface thereof faces away from the support roll 42. At this time, the web W is curved so that the surface on which the hairline processing is performed is on the outside. Thereby, the fluff C which is not completely separated from the web W main body but part of which remains connected to the web W main body, particularly the web W main body on the rear side along the traveling direction of the web W Of the fluff C that remains connected, the fluff C1 located at a portion of the web W that is supported along the outer peripheral surface 43 of the support roll 42 is raised from the surface of the web W. Therefore, the fluff C can be easily separated from the web W by the fluff separation device.

  In the present embodiment, in the fluff separation step, the fluff C is separated from the web W by bringing the blade 46 constituting the fluff separation device into contact with the web W supported along the outer peripheral surface 43 of the support roll 42. . In the example shown in FIGS. 3 to 5, the blade 46 has a linear blade extending parallel to the central axis of the support roll 42, and this blade is supported along the outer peripheral surface 43 of the support roll 42. The fluff C on the web W is separated from the web W in contact with the web W. In other words, the blade of the blade 46 is configured to contact the portion of the web W supported along the outer peripheral surface 43 of the support roll 42.

  As shown in FIG. 5, in the plane orthogonal to the central axis of the support roll 42, the blade 46 has a tangential direction dt to a location where the blade contacts the web W and a normal to the location. It is inclined with respect to the direction dn. In particular, in the illustrated example, in the plane perpendicular to the central axis of the support roll 42, the blade of the blade 46 has a cutting edge behind the web W in the tangential direction dt and the web W in the normal direction dn. It is inclined with respect to the tangential direction dt and the normal direction dn so as to face the side.

  Thereby, the blade of the blade 46 is inserted between the fluff C raised from the surface of the web W and the web W main body along with the movement along the outer peripheral surface 43 of the support roll 42 of the web W. The connecting portion (connected portion) between the web W main body can be cut with the blade of the blade 46. In this way, the fluff C is separated from the web W main body. A part of the fluff C separated from the web W main body accumulates on the blade 46, and another part of the fluff C adheres to the web W.

  In the present embodiment, in the hairline processing unit 30, a large number of abrasive grains dispersed in the polishing film 32 scrape the surface of the web W from the front side to the rear side along the traveling direction of the web W. . The fluff C that may occur at this time mainly has a fixed end connected to the web W main body on the rear side along the traveling direction of the web W, and is separated from the web W main body on the front side along the traveling direction of the web W. Has a free end. In this embodiment, in order to separate the fluff C from the web W main body more reliably, in the fluff separation unit 40, the blade 46 causes the fluff C to move from the front side to the rear side along the traveling direction of the web W. I try to scrape it off. That is, in the present embodiment, the hairline processing unit 30 scrapes the fluff C in the direction in which the surface of the web W is scraped to perform the hairline processing, and the fluff separation unit 40 separates the fluff C from the web W. The direction of dropping is the same. Thereby, the fluff C can be separated from the surface of the web W while suppressing the fluff C raised from the surface of the web W from sleeping on the surface of the web W. In particular, the fluff C can be separated from the surface of the web W while being raised from the surface of the web W by the blade 46. Therefore, the fluff C can be more reliably separated from the web W main body.

[Fuzz removal process]
Next, a fluff removal step of removing the fluff C separated from the web W and attached to the web W in the fluff separation step from the web W is performed. In the fluff removing step, the fluff C is removed from the web W by the adhesive roll 52. For example, the web W is sandwiched between the adhesive roll 52 having the adhesive layer on the outer peripheral surface 53 and the guide roll 54, and the fluff C attached to the web W is removed from the web W by adhering to the adhesive layer of the adhesive roll 52. To do. Alternatively, the web W may be sandwiched between the two adhesive rolls 52, and the fluff C attached to the web W may be attached to the adhesive layer of each adhesive roll 52 and removed from the web W.

[Winding process]
The web W from which the fluff C is removed in the fluff removal step is wound into a roll. The web W is wound on the winding shaft by rotating the winding shaft of the winding unit 60 with a driving force from a driving source such as a motor.

  The hairline processing apparatus 10 according to the present embodiment includes a feeding unit 20 that feeds the web W, a hairline processing unit 30 that performs hairline processing on the web W fed from the feeding unit 20, and hairline processing.

The fluff C on the web W supported along the outer peripheral surface 43 of the support roll 42 is separated from the web W.

  According to the hairline processing apparatus 10 and the hairline processing method, the web W is curved with the surface on which the hairline processing is performed outside in a state where the web W is supported along the outer peripheral surface 43 of the support roll 42. Can be made. Thereby, the fluff C which is not completely separated from the web W main body but part of which remains connected to the web W main body, particularly the web W main body on the rear side along the traveling direction of the web W Of the fluff C that remains connected, the fluff C1 located at a portion of the web W that is supported along the outer peripheral surface 43 of the support roll 42 is raised from the surface of the web W. Therefore, the fluff C, which is not completely separated from the web W main body and part of which remains connected to the web W main body, in particular, is connected to the web W main body on the rear side along the traveling direction of the web W. The remaining fluff C can be easily separated from the web W main body.

  The fluff separation device of the hairline processing apparatus 10 according to the present embodiment has a blade 46 that abuts on the web W supported along the outer peripheral surface 43.

  Moreover, the hairline processing method of this Embodiment isolate | separates the fluff C from the web W by making the blade 46 contact | abut to the web W supported along the outer peripheral surface 43 in a fluff separation process.

  According to such a hairline processing apparatus 10 and a hairline processing method, between the fluff C raised from the surface of the web W and the web W main body along with the movement along the outer peripheral surface 43 of the support roll 42 of the web W. In addition, the blade of the blade 46 can be inserted, and the connecting portion (connected portion) between the fluff C and the web W main body can be cut with the blade of the blade 46. Therefore, the fluff C can be separated from the web W more easily using a fluff separation device having a simple configuration.

  In the hairline processing apparatus 10 of the present embodiment, the blade 46 has a fluff for separating the fluff C from the web W in the fluff separation unit 40 and the direction in which the surface of the web W is scraped in order to perform the hairline processing in the hairline processing unit 30.

  In the hairline processing method of the present embodiment, the web W is a film formed of resin. In particular, in the hairline processing method of the present embodiment, the resin is polyethylene terephthalate.

  When the web W formed of the film formed of resin is hairline processed, compared to the case where the other web W formed of metal foil or the like is hairline processed, it is not completely separated from the web W main body, Fluff C that part of which remains connected to the main body of the web W tends to occur. In particular, when the resin is polyethylene terephthalate (PET), fluff C that is not completely separated from the web W main body but remains partially connected to the web W main body is more likely to occur. Therefore, when the web W is a film formed of a resin, particularly when the resin is polyethylene terephthalate, the hairline processing method of the present embodiment is particularly effective.
