Description

  The present invention relates to a liner transfer device, and more particularly to a liner transfer device that forms an overlapping portion of release liners in a manufacturing process of an aqueous gel sheet.

  The aqueous gel sheet is formed by laminating a gel-like paste containing moisture and a release liner on one surface of a nonwoven fabric serving as a base material. In order to make it easy for the user to easily remove the release liner from the layer on which the plaster is applied, the aqueous gel sheet release liner is divided into, for example, two sheets at the substantially central portion of the aqueous gel sheet. There is something. Further, the two release liners are provided so that the release liners overlap each other at a substantially central portion. And the user can peel off a release liner easily by picking the release liner of the piled site | part.

  By the way, in order to manufacture a release liner having such an overlapping portion and the overlapping portion serving as a user's knob, for example, two long release liners are unwound by separate unwinding means, 2 Two release liners were positioned so as to overlap each other by a predetermined width to form an overlapping portion.

  Further, as another method, for example, a wide original fabric is cut in a direction parallel to the transport direction of the original fabric to form narrow liners, and the respective narrow liners are transferred so as to overlap each other by a predetermined width. The method of shifting in the direction orthogonal to the direction was taken.

  However, in the apparatus using the method as described above, the narrow liner moves obliquely in order to move the narrow liner in a direction orthogonal to the transfer direction, and the overlapping portion also has a uniform width. Not formed. Furthermore, it is necessary to provide a longer transfer direction in order to bring the overlapping portion closer to a uniform width.

  As shown in FIG. 3, the liner transfer device 1 unwinds the roll 2 and unwinds the unwinding portion 20 and the unwinding portion 20 unwinded by the unwinding portion 20 in parallel with the transfer direction. The slitter part 30 which cuts in the direction and forms the narrow liner 3, and each narrow liner 3 is changed to the direction substantially orthogonal to a transfer direction, and adjacent narrow liners 3 and 3 are predetermined. It is comprised from the overlap formation part 40 which forms the overlap part 4 which overlapped in width.

  The raw fabric 2 is a wide liner serving as a release liner for the aqueous gel sheet to be formed, and is a moisture-impermeable resin film made of release paper, polyester, or polypropylene, for example. The raw fabric 2 is embossed in consideration of the peelability and adhesion to the plaster body 120. The width of the raw fabric 2 is longer than, for example, three times the length of the aqueous gel sheet 101 in the longitudinal direction. The raw fabric 2 has a long liner wound in a roll shape and is installed at a predetermined position of the unwinding portion 20.

  In addition, the raw fabric 2 is not limited to the width as described above that is longer than three times the length in the longitudinal direction of the aqueous gel sheet 101, and the width may be changed depending on the size of the formed aqueous gel sheet. Good.

  The unwinding part 20 is connected to the chuck member 21 that holds the original fabric 2 at the core, the brake 22 is connected to the chuck member 21 and adjusts the unwinding speed of the original fabric 2, and the original fabric 2 is pulled out from the core. It is comprised from the drawing roll 23 which sends the raw fabric 2 to the slitter part 30 provided in the back | latter stage.

  The chuck member 21 can unwind the raw fabric 2 wound in a roll shape, and is a chuck system that sandwiches both ends of the core of the original fabric 2. Specifically, one end portion of the core of the original fabric 2 has a fixed chuck 21a, and the other end portion has a press chuck 21b, which are positioned on the same straight line. The press chuck 21b is variable in the width direction of the original fabric 2 (the direction indicated by the arrow Y in FIG. 3A), and the original fabric 2 having various widths is sandwiched between the fixed chuck 21a and the press chuck 21b with a predetermined pressure.

  The brake 22 is connected to the fixed chuck 21a, and the rotational speed of the fixed chuck 21a is adjusted by, for example, an air brake, and the unwinding speed of the raw fabric 2 is adjusted.

  The drawing roll 23 is a roll provided between the chuck member 21 and the slitter unit 30, and rotates the drive motor 23 a connected to the rotation shaft to rotate the roll 2 into the slitter unit. Pull out to 30. The drawer roll 23 has a dancer roll, and the speed of the drive motor 23a is adjusted according to the position of the dancer roll to keep the tension of the original fabric 2 constant.

  In addition, the drawer roll 23 can also be provided with other yard meters, and the amount of unwinding of the raw fabric 2 may be grasped by the user.

  The slitter part 30 is comprised from the upper blade and lower blade which are provided in the predetermined position in three places in the width direction of the raw fabric 2, and the raw fabric 2 pinched | interposed with an upper blade and a lower blade is the transfer direction (FIG. 3). (A) Cut in a direction parallel to the middle arrow X direction) to form four narrow liners 3 having a predetermined width. In this description, the narrow liner 3 will be described as narrow liners 3a, 3b, 3c, and 3d, respectively.

  The overlap forming unit 40 moves the narrow liners 3a, 3b, 3c, and 3d in a substantially orthogonal direction (the arrow Y direction in FIG. 3) so that the adjacent narrow liners 3 overlap each other by a predetermined width. Transfer direction change rods 41a, 41b, 41c, 41d (hereinafter collectively referred to as transfer direction change rods 41) and respective narrow liners 3a, 3b, 3c, 3d transferred in the arrow Y direction. It is comprised from the several guide roll 42 (refer FIG.3 (B)) to overlap.

  The transfer direction changing rod 41 is made of a metal rod having a small amount of friction with the original fabric 2, for example, having a surface finish. The transfer direction changing rod 41 has an axis with respect to the transfer direction (arrow X direction in FIG. 3 (A)) of the narrow liner 3 and the width direction (Y direction in FIG. 3 (A)) of the narrow liner 3. It is fixed so that it is inclined about 45 degrees. The transfer direction changing rod 41 changes the transfer direction of the narrow liner 3 transferred in the X direction to the Y direction.

  Each of the transfer direction changing rods 41a, 41b, 41c, and 41d is a narrow liner 3a, 3b, 3c, 3d adjacent when the narrow liners 3a, 3b, 3c, 3d change the transfer direction in the Y direction. They are positioned so as to overlap each other by a predetermined width in the X direction. Specifically, the axis of the transfer direction change bar 41b is provided on the slitter unit 30 side in the X direction from the axis of the transfer direction change bar 41a. Similarly, the transfer direction changing rod 41c is provided on the slitter unit 30 side by a predetermined distance in the X direction from the axis of the transfer direction changing rod 41b. Similarly, the transfer direction changing rod 41d is provided on the slitter unit 30 side at a predetermined distance in the X direction from the axis of the transfer direction changing rod 41c.

  In addition, the respective transfer direction changing rods 41a, 41b, 41c, and 41d are alternately shifted in height in the Z direction (the arrow Z direction in FIG. 3B) orthogonal to the X direction and the Y direction. . The reason why the height positions of the adjacent moving direction change bars 41 are alternately shifted is to secure, for example, a space for a support member that supports each of the adjacent transfer direction change bars 41a and 41b. Furthermore, each transfer direction change bar 41 can adjust the position in the X direction by using an adjusting member (not shown), and can adjust the overlapping width between adjacent narrow liners 3.

  The guide roll 42 is a roll that overlaps the narrow liners 3 that have different height positions (in the direction of arrow Z in FIG. 3B) and are transported in the Y direction. The guide roll 42 forms an overlapping portion 4 in which the narrow liners 3 overlap each other with a predetermined width by the transfer direction changing rod 41 when the narrow liners 3 are overlapped.

  The overlapping portion 4 is a portion where adjacent narrow liners 3 overlap each other as shown in FIG. 4A when the narrow liners 3 are overlapped by the guide roll 42. The overlapping portion 4 has a uniform width with respect to the transfer direction (the arrow Y direction in FIG. 3A). Moreover, since the width | variety of the overlap part 4 becomes a knob | pick part at the time of peeling the narrow liner 3 which is a peeling liner from the paste 120 by the user of the water-based gel sheet 101, it can only be easily picked by the user. The width is formed, for example, 5 mm. In addition, the width | variety of the overlap part 4 is not restricted above, Any width | variety may be sufficient if it is a width | variety which can be easily picked by the user.

  FIG. 4B is a view showing the relationship between the aqueous gel sheet 101 formed by being cut by the cutting portion 140 provided at the subsequent stage of the liner transfer device 1 and the overlapping portion 4. As shown in FIG. 4B, the overlapping portion 4 is provided over the entire short-side direction of the finally formed aqueous gel sheet 101 indicated by a one-dot chain line.

  The liner transfer device 1 configured as described above unwinds the wide original fabric 2 wound in a roll shape by the unwinding unit 20 and the four narrow liners 3a, 3b, 3c by the slitter unit 30. 3d is formed, the transfer direction is changed by approximately 90 degrees by the overlap forming portion 40, and adjacent narrow liners 3 are overlapped by a predetermined width to form the overlap portion 4.

  In addition, the liner transfer device 1 has a transfer direction changing rod 41 in the overlap forming portion 40, and changes the transfer direction of each narrow liner 3 by approximately 90 degrees, and the adjacent narrow liners 3 are adjacent to each other. Since the transfer direction changing rod 41 is displaced with respect to the X direction so as to overlap with each other by a predetermined width, it is possible to form the overlapping portion 4 serving as a knob for peeling off the aqueous gel sheet 101 with a simple configuration.

  Moreover, since the liner transfer device 1 forms the overlapping portion 4 by the transfer direction changing rod 41, the narrow liner is gradually shifted in the width direction to form the overlapping portion, or two separate rolls are formed. Space saving can be achieved by forming the overlapped portion by overlapping the wound original fabric.

  In addition, although the overlapping part 3 described having formed over the transversal direction of the substantially rectangular water-based gel sheet 101, you may make it form not only this but the whole longitudinal direction.

  Moreover, although the slit part 30 demonstrated forming four narrow liners 3a, 3b, 3c, 3d, it is not restricted to this, For example, it is preferable to form seven narrow liners 3 Also good. Further, for example, as shown in FIG. 5A, the slit portion 30 is configured so that the widths of the narrow liner 3a and the narrow liner 3d are different from the widths of the narrow liner 3b and the narrow liner 3c. May be. At this time, as shown in FIG. 5 (B), the completed aqueous gel sheet 101 does not have a portion to be discarded at both ends, and the material can be used without waste.
