Definitions

  • the present invention relates to a method for manufacturing a roll which is a long element such as adhesive tape rolled up, and relates to such a roll.
  • a roll having a predetermined width is made through a manufacturing method in which a wide sheet is rolled up on a winding unit, and then cut at every predetermined width by using a cutter.
  • this manufacturing method the thickness of the cutter and the angle of the blade edge are easily variable, and for this reason, dimensional error relative to the width direction easily becomes large at the center side of the roll where the blade edge is deeply inserted.
  • a manufacturing method in which a wide sheet is cut before it is rolled up on the winding unit, thereby forming long elements having a predetermined width, and then winding these long elements on the winding unit while restricting the position in the width direction.
  • PTL 1 discloses the following manufacturing method. Namely, an edge regulating roller is prepared which has a pair of flanges at both ends of the roller relative to the width direction. The flanges are tilted outwardly so that the distance between the flanges increases towards outside. This edge regulating roller is rotatably disposed at a reaching position of each long element to the roll. The long element is then rolled up while its positions relative to the width direction is regulated by having its ends relative to the width direction abut the flanges of the edge regulating roller.
  • PTL 2 discloses the following manufacturing method. Namely, a guide block is prepared which has a pair of flanges at both ends of the guide block relative to the width direction. The flanges are tilted from the both ends by 0 to 20 degrees. This guide block is fixed to a reaching position of each long element to the roll. The long element is then rolled up while regulating its position relative to the width direction by having its ends abut the flanges of the guide block.
  • the distance between the flanges increases from the base side towards the leading end side.
  • the base parts of the flanges on the edge regulating roller or those of the guide block need to be approximated to the roll surface to the extent that the base parts of the flanges contact the roll surface.
  • the adhesive agent oozing out from the long element may adhere to the flanges.
  • This oozing-out adhesive agent causes an unstable braking force, between the roll and the flanges, consequently making the tension of the long element in process of being rolled up unstable; i.e., causes excessive tension or insufficient tension.
  • This unstable tension may serve as a cause of significant variation in the width of the long element, leading to significant irregularity in the roll of the long element in the width direction.
  • the present invention is made, and it is an object of the present invention to provide a method of manufacturing a roll, in which amount of irregularity in the roll of a long element is sufficiently reduced, even in cases of winding a narrow long element having an adhesive agent on a roll having a large diameter.
  • An aspect of the present invention is a method of manufacturing a roll in which a long element having an adhesive agent and a predetermined width is wound by a winding unit so that the long element forms a plurality of wound layers in a radial direction from the winding unit to a roll surface, the method including: arranging, in a position distant from the roll surface, an alignment groove having a pair of groove side surfaces configured to contact both ends of the long element relative to the width direction; causing each of the pair of groove side surfaces to be on the same plane as the corresponding one of a pair of wound end surfaces formed by both ends of the wound layers relative to the width direction; and placing the long element on the alignment groove and winding the long element on the roll.
  • the alignment groove when the long element is wound by the winding unit, the alignment groove is positioned so that each of the pair of groove side surfaces is on the same plane as the corresponding one of the pair of wound end surfaces formed by both ends of the wound layers relative to the width direction. Since the forwarding direction of the long element from the alignment groove to the roll surface matches with the winding direction of the roll, winding is carried out while the long element is positioned relative to the width direction by the alignment groove. At this time, even when the adhesive agent on the long element adheres to the alignment groove, the adhesive agent having adhered does not generate a braking force between the alignment groove and the roll surface, because the alignment groove is in a position distant from the roll surface.
  • the long element is wound with a stable tension while being positioned relative to the width direction. Therefore, the amount of irregularity in the layers of the long element is sufficiently reduced, even in cases of winding a narrow long element having an adhesive agent on a roll having a large diameter.
  • the aspect of the present invention may be adapted so that the alignment groove has a groove depth greater than the thickness of the long element.
  • the above structure in which the groove depth is greater than the thickness of the long element causes the both ends of the long element relative to the width direction, having departed from the alignment groove to contact the groove side surfaces of the alignment groove longer than a case where the groove depth is smaller. Therefore, the groove side surfaces in contact with the both ends of the long element relative to the width direction improve the positional regulation of the long element relative to the width direction, It is therefore possible to further sufficiently reduce the irregularity in the layers of long element.
  • the aspect of the present invention may be adapted so that the winding is carried out while the alignment groove is moved in a forwarding direction of the long element.
  • the adhesive agent is less likely collected, as compared with a case where the adhesive agent is accumulated in a position where adhesion of the adhesive agent has occurred, because even when the adhesive agent adheres to the alignment groove, the adhesive agent having adhered moves in the forwarding direction of the long element, along with the alignment groove. Since a rapid increase in the amount of adhesive agent on the alignment groove is prevented, it is possible to variation in the tension of the long element caused by the adhesive agent staying in the alignment groove generating a braking force to forwarding of the long element. As the result, the width of the long element is stabilized from the beginning to the end of winding. Therefore, the amount of irregularity in the layers of the long element is made sufficiently small, even in cases of winding a narrow long element having an adhesive agent on a roll having a large diameter.
  • the aspect of the present invention may be adapted so that the alignment roller having the alignment groove around its circumference is rotated about the axis of the alignment roller, thereby moving the alignment groove in the forwarding direction of the long element.
  • the above structure enables adjustment of the relative position relation and the speed difference between the groove side surfaces of the alignment groove and the long element, by raising or reducing the rotation speed of the alignment roller. This facilitates adjustment of the bonding force amongst the wound layers on the roll to a desirable value.
  • Another aspect of the present invention is a roll manufactured by the above described manufacturing method such that a maximum amount of irregularity in the both ends of the wound layers of the long element relative to the width direction is 0 mm to 1.0 mm, preferably, 0 mm to 0.7 mm, and more preferably 0 mm to not more than 0.5 mm.
  • the above structure makes it easy to confirm that the roll is manufactured by the method of the present invention for manufacturing a roll.
  • the present invention yields a roll having sufficiently small amount of irregularity in the layers of a long element on the roll.
  • a roll manufacturing method of present embodiment is a method in which a long element 72 having an adhesive agent and having a predetermined width is rolled up on a winding unit 8, thereby manufacturing a roll 73 having a plurality of wound layers 73b of the long element 72 in a radial direction, from the winding unit 8 to the roll surface 73a.
  • the method includes an alignment roller setting process, a long element setting process, an unwinding process, a cutting process, an alignment and winding process, and a take-out process.
  • the roll 73 is detailed later.
  • An alignment roller preparation process is a process of selecting a desirable alignment roller 6 from a plurality of types of alignment rollers 6, and mounting the alignment roller 6 to an alignment devise 2. Specifically, as shown in Fig. 1 , specification of a product such as the diameter and width of a roll 73 to be produced which is shown in FIG. 4 , and the thickness of the wound layer 73b (long elements 72) is read out. Then, an alignment roller 6 having a groove width corresponding to the width of the long elements 72 and a groove depth which is two or more times the thickness of the wound layer 73b is selected from the plurality of types of alignment rollers 6. The selected alignment roller 6 is then moved from storage, and the rotation shaft 63 of the alignment roller 6 is rotatably mounted to a not-shown roller-supporting structure of the alignment device 2.
  • a long element setting process is a process carried out subsequent to the alignment roller preparation process, and is a process for enabling winding of a long element 72 corresponding to the roll 73 to be produced.
  • a plurality of winding units 8 each corresponding to the width of the wound layer 73b (long elements 72) of the roll 73 are mounted to a winding roller 51.
  • Each of the winding units 8 is movable in the width direction of the winding roller 51.
  • the intervals between the winding units 8 are adjusted so that the position of each of the winding unit 8 and the position of each alignment groove 62 of the corresponding alignment roller 6 relative to the vertical direction match with each other.
  • the positional relationship is adjusted as follows.
  • the distance between the winding unit 8 and the alignment roller 6 can be increased or decreased, the distance between the winding unit 8 and the alignment roller 6 is reduced to the extent that the alignment roller 6 is close to the circumference of the winding roller 51.
  • the winding unit 8 is engaged with the alignment groove 62 of the alignment roller 6. This way, the alignment groove 62 of the alignment roller 6 and the winding unit 8 are positioned to match each other, relative to the vertical direction.
  • a plate-like or a belt-like position adjusting member is placed in the vertical direction. Using this position adjusting member as the reference, the positions of the winding unit 8 and that of the alignment groove 62 of the alignment roller 6 are adjusted. Note that a laser beam may be used as the position adjusting member. When the position adjustment is completed as described above, all the winding units 8 are fixed to the winding roller 51.
  • a sheet roll 7 formed by a sheet 71 whose thickness is the same as the thickness of the wound layer 73b (long elements 72) of the roll 73.
  • the sheet roll 7 is taken out from a not-shown roll storage and is conveyed to the unwind device 3 by a suspending device 91 of the roll conveyance device 9. Note that the sheet roll 7 has a thickness which is at least the thickness of the long element 72, and has a width which is two or more times the width of the long element 72.
  • the sheet roll 7 is then set to the unwind device 3.
  • the leading end portion of the sheet 71 positioned on the outer surface of sheet roll 7 is unwound by an operator and is forwarded to a cutting apparatus 4, through a conveyance path formed by guide rollers or the like.
  • the sheet 71 is cut into a plurality of long elements 72 each having the roll width, by the cutting apparatus 4.
  • long elements 72 odd-number th long elements 72 when counted in a width direction are directed downward, while even-number th long elements 72 when counted in the width direction are directed upward.
  • the long elements 72 directed downwards are each placed on an alignment groove 62 of the corresponding alignment roller 6 on the lower side as is the case of placing a belt on a pulley, and are brought into a setting-standby state during which the leading end portion is the free end.
  • the long elements 72 directed upwards are each placed on the alignment groove 62 of the corresponding alignment roller 6 on the upper side, and are brought into the setting-standby state during which the leading end portion is the free end.
  • each long element 72 is fixed to the corresponding winding unit 8 disposed immediately below or immediately above. That is, a pair of groove side surfaces 62a of the alignment groove 62 and a pair of wound end surfaces 73c formed by both ends of the wound layer 73b relative to the width direction are disposed so that each groove side surface 62a and the corresponding end of the wound layer 73b are present on the same plane.
  • the positions of the long element 72 and the winding unit 8 match with each other relative to the vertical direction, therefore the length of the long element 72 easily directed and fixed to the winding direction of the winding unit 8.
  • This operation of fixing may be done by adhering the adhesive agent on the long elements 72 to the winding unit 8.
  • the distance between the winding unit 8 and the alignment roller 6 can be increased or reduced, the distance between the winding unit 8 and the alignment roller 6 is reduced to the extent that the alignment roller 6 is nearby the circumference of the winding roller 51.
  • the winding unit 8 is engaged with the alignment groove 62, and the groove bottom surface 62b of the alignment groove 62 is pressed against the long element 72 in the direction of the winding unit 8.
  • the fixed state of the winding roller 51 and the winding unit 8 is temporarily released.
  • the state of the winding unit 8 fixed relative to the width direction of the winding roller 51 is maintained by the groove side surfaces 62a, while the winding unit 8 is rotatable about the winding roller 51.
  • the winding unit 8 is rotatable, while its positional relation to the alignment groove 62 is maintained. After that, as shown in Fig. 2 , the winding unit 8 is rotated by an operator to get rid of slackness of the long element 72. When the slackness of all the long elements 72 are gotten rid of, the winding roller 51 and the winding unit 8 are again brought into the fixed state. Then, the distance between the winding unit 8 and the alignment roller 6 is increased.
  • the unwinding process, the cutting process, and the aligning and winding process are carried out at the same time after the long element setting process.
  • the unwinding process is a process of unwinding the sheet 71 of the sheet roll 7 set to the unwind device 3 at a predetermined forwarding speed.
  • the cutting process is a process for cutting the sheet 71 unwound from the unwind device 3 into a plurality of long elements 72 having a predetermined width.
  • the aligning and winding process is a process for winding the long elements 72 to the winding units 8, at the same time.
  • rotation of the winding units 8 on the wind device 5 and rotation of the sheet roll 7 on the unwind device 3 are started at the same time.
  • the rotation speed of the wind device 5 and that of the unwind device 3 are adjusted to keep the constant tension of the sheet 71 and the long elements 72 being conveyed. This way, cutting width by the cutting apparatus 4 is stabilized, thus highly accurately forming the long elements 72 each having a predetermined width. Then, aligning and winding process takes place at the wind device 5 at a stable operation.
  • the rolls 73 are manufactured as follows. Namely, as shown in Fig. 3 and Fig. 4 , while the alignment groove 62 having the pair of groove side surfaces 62a in contact with the both ends of the long elements 72 relative to the width direction is disposed in a position distant from the roll surface 73a, and the pair of groove side surfaces 62a and the pair of wound end surfaces 73c formed by the both ends of the wound layers 73b relative to the width direction are disposed so that each groove side surface 62a is on the same plane as the corresponding one of the wound end surface 73c, each of the long elements 72 is placed on the corresponding alignment groove 62 having a groove depth greater than the layer thickness of the wound layers 73b and is moved and wound in a winding direction (forwarding direction) which corresponds to the rotating direction of the winding roller 51.
  • a winding direction forwarding direction
  • the distance in the above description that the alignment groove 62 is disposed in a position distant from the roll surface 73a is preferably set so that the length of the long element 72 with respect to the groove depth of the alignment groove 62 is such that (1) the possibility of having the alignment roller 6 contact the roll surface 73a due to mechanical vibration or the like is prevented, and (2) an oscillation errors of the long elements 72 relative to the width direction is an insignificant level.
  • the alignment groove 62 is positioned so that each of a pair of wound end surfaces 73c formed by the both ends of the wound layers 73b relative to the width direction is on the same plane as the corresponding one of a pair of groove side surfaces 62a. Since the forwarding direction of the long element 72 from the alignment groove 62 to the roll surface 73a matches with the winding direction on the roll 73, the long element 72 is wound while being positioned relative to the width direction by the alignment groove 62.
  • the alignment groove 62 having a groove depth greater than the thickness of the long element 72 causes the both ends of the long element 72 relative to the width direction having departed the alignment groove 62 to be in contact with the groove side surfaces 62a of the alignment groove 62 longer than a case where the groove depth is smaller.
  • These groove side surfaces 62a in contact with the both ends of the long element 72 relative to the width direction improves the accuracy in position regulation relative to the width direction.
  • the irregularity in the roll of long element 72 is further sufficiently reduced.
  • the adhesive agent oozing out from the both ends of the long element 72 may adhere to the alignment groove 62.
  • the alignment groove 62 is fixed, the adhesive agent once adhered to the alignment groove 62 induces collection of more adhesive agent to the alignment groove 62.
  • the adhesive agent accumulated in the alignment groove 62 sticks the adhesive agent on the long element 72 of each wound layer 73b, and generates a braking force between the alignment groove 62 and the long element 72 during the winding. Rapid increase in the amount of accumulated adhesive agent causes an excessively large tension to the long element 72 being wound.
  • the rapidly increased tension causes a change in the width of the long element 72, which may cause an increase in the amount of irregularity relative to the width direction, amongst the wound layers 73b of the long element.
  • the width of the long element 72 therefore is stabilized from the beginning to the end of winding, which enables sufficient reduction of the amount of irregularity relative to the width direction of each wound layer 73b in the roll of the long element 72, even when winding a narrow long element 72 to a roll having a large diameter.
  • the alignment roller 6 of the present embodiment may be rotatably supported by the alignment device 2, or may be supported so that its rotation speed is adjustable by means of adjusting the rotation drive force of the alignment device 2.
  • the way of supporting to enable adjustment of rotation speed is such that the alignment groove 62 is moved in the forwarding direction of the long element 72 when the alignment roller 6 is rotated about its axis.
  • the support is such that the rotation speed is adjustable, it is possible to adjust the relative positional relation and the difference in the speed of the groove side surfaces 62a of alignment groove 62 and the long elements 72 simply by adjusting the rotation speed of the alignment roller 6. Therefore, the adhesive force among the wound layers 73b of the roll 73 is easily adjusted to a desirable value.
  • the wind device 5 and the unwind device 3 are stopped. After that, all the long elements 72 are cut between the roll 73 and the alignment roller 6, and enters the setting-standby state as shown in Fig. 1 .

The pressing members switch the state of the winding unit 8 and the winding roller 51 between an inserted state and a fixed state.
  • On the downstream side of the wind device 5 is a take-out device.
  • the take-out device is capable of taking out the products.
  • the take-out device may be a bogie capable of carrying thereon the roll 73, or a roll conveyance device 9.
  • the alignment roller 6 for use in the roll manufacturing device 1 having the above structure has a cylindrical roll main body 60; one or more alignment grooves 62 formed on the circumference of the roll main body 60; and a pair of rotation shafts 63 ( Fig. 1 ) projecting from both ends of the roll main body 60.
  • the or each alignment groove 62 is formed on the circumference of the roll main body 60.
  • the axis of the roll main body 60 coincides with the axis of the rotation shaft 63. This way, when the alignment roller 6 rotates about its axis while being fixed relative to the width direction (axial direction), the alignment groove 62 is moved at the same position relative to the width direction.
  • the alignment groove 62 is formed by the circumferential surface of the roll main body 60, and the groove side surface walls 61 formed on the circumferential surface of the roll main body 60.
  • the circumferential surface of the roll main body 60 forms a flat groove bottom surface 62b of the alignment groove 62, while the groove side surface walls 61 form flat groove side surfaces 62a of the alignment groove 62.
  • the alignment groove 62 having a groove bottom surface 62b parallel to the axial direction of the alignment roller 6 and the groove side surfaces 62a matching with radial directions of the alignment roller 6 form a rectangular cross section such that an outer portion relative to a radial direction of the alignment roller 6 is opened.
  • the groove width A2 of the alignment groove 62 substantially matches with the width L4 of the long element 72. Note that, by the groove width A2 of the alignment groove 62 substantially matching with the width L4 of the long element 72, it means that the groove width A2 matches with the width L4 so that the amount of irregularity in the roll 73 relative to the width direction is within an allowable range.
  • the groove width A2 of the alignment groove 62 may match with the width L4 of the long element 72, or be greater or smaller than the width L4 of the long element 72, provided that the amount of irregularity in the roll 73 relative to the width direction is within the allowable range.
  • the groove depth A1 of the alignment groove 62 is set to be twice or more the thickness L1 of the long element 72. With the groove depth A1 greater than the thickness of wound layers 73b, the alignment groove 62 enables each of the pair of groove side surfaces 62a to be on the same plane as the corresponding one of the pair of wound end surfaces 73c formed by both ends of the wound layers 73b relative to the width direction.
  • the width A3 of the groove side surface wall 61 may be the same as or different from the groove width A2 of the alignment groove 62.
  • the lower wind device 5 is able to wind the odd number th or the even number th long elements 72 from the cutting apparatus 4 and having a predetermined width and the upper wind device 5 is able to wind the odd number th or the even number th long elements 72.
  • the alignment rollers 6 to be mounted to the upper or lower alignment device 2 may have different groove widths A2 of the groove side surface wall 61. In this case, by setting two different cutting widths in the cutting apparatus 4, it is possible to wind two different types of long elements 72 by the wind devices 5.
  • the present embodiment deals with a case where the top portion of the groove side surface wall 61 of the alignment roller 6 is flat, i.e. , the top portion has a surface matching with the axial direction; however, the present invention is not limited to this.
  • the top portion 613 of the groove side surface wall 61 of the alignment roller 6 may be curved so as to project radially outward.
  • the top portion 613 of the groove side surface wall 61 guiding the long element 72 towards the alignment groove 62 prevents deterioration in the accuracy of alignment of each of the wound layers 73b on the roll 73, damages, bending, contamination or the like of the end portion of the roll 73 relative to the width direction.
