Summary of the Invention

Problems to be Solved by the Invention

[0004] The apparatus shown in Patent Document 1 uses an apparatus including a front roll, a rear roll, and a shaft for rotatably supporting an adhesive tape. When performing a curing operation, in addition to the adhesive tape, it is necessary to carry a heavy and bulky apparatus, which is cumbersome.

[0005] An object of the present invention is to provide an adhesion structure of an adhesive tape that can adhere an adhesive tape to an object with a simple structure when the adhesive tape is adhered to the object, and an adhesion method of an adhesive tape using the same.

Means for Solving the Problems

[0006] An adhesive tape sticking structure having an adhesive tape roll, a front roll disposed in front of the adhesive tape roll, and a rear roll disposed behind the adhesive tape roll, wherein the rotating surface of the adhesive tape roll is in contact with the rotating surface of the front roll, the rotating surface of the adhesive tape roll is in contact with the rotating surface of the rear roll, the ratio of the outer diameter of the front roll to the outer diameter of the adhesive tape roll is 50% or more and 150% or less, the ratio of the outer diameter of the rear roll to the outer diameter of the adhesive tape is 50% or more and 200% or less, the width of the front roll is equal to the width of the adhesive tape roll or is configured to be larger than the width of the adhesive tape roll, the adhesive surface of the adhesive tape pulled out from the adhesive tape roll is disposed on the inner surface of the roll, and the adhesive tape is wound downward through above the front roll, passes under the adhesive tape roll and under the rear roll, and is stuck to an object, thereby solving the above problems.

[0007] Further, the above problems are solved by an adhesive tape sticking method in which the rear roll of the above adhesive tape sticking structure presses the adhesive tape roll to rotate the adhesive tape roll and stick the adhesive tape to an object.

[0008] In the above adhesive tape sticking structure or adhesive tape sticking method, the rotating surface of the adhesive tape roll is in contact with the rotating surface of the rear roll. When the rear roll presses the adhesive tape roll, the adhesive tape roll starts to rotate by the force pushed forward. Since the rotating surface of the adhesive tape roll is in contact with the rotating surface of the front roll and the rotating surface of the rear roll, the front roll and the rear roll rotate as the adhesive tape roll rotates. Since the adhesive tape is wound around the front roll, the rotation of the front roll feeds out the adhesive tape from the adhesive tape roll. The fed-out adhesive tape is pressed by the front roll, the adhesive tape roll, or the rear roll and stuck to the object.

[0009] In the above-described adhesive tape sticking structure or the adhesive tape sticking method, it is preferable that the rear roll includes a support portion that rotatably supports the rear roll and a grip portion connected to the support portion. According to this configuration, the user can stick the adhesive tape to the object by pushing the rear roll forward through the grip portion to rotate the rear roll, the adhesive tape roll, and the front roll.

[0010] In the above-described adhesive tape sticking structure or the adhesive tape sticking method, the adhesive tape may be provided with an adhesive layer in a streak shape along the direction in which the adhesive tape is fed out. By making the adhesive layer streak-shaped, the resistance when feeding out the adhesive tape from the adhesive tape roll is reduced, and it becomes easier to apply the adhesive tape.

Advantages of the Invention

[0011] According to the present invention, there can be provided an adhesive tape sticking structure that can stick an adhesive tape to an object with a simple structure when sticking the adhesive tape to the object, and an adhesive tape sticking method using the same.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, an embodiment of the adhesion structure of the adhesive tape of the present invention and the method of adhering the adhesive tape using the same will be described. Each of the embodiments shown below is merely a limited example of the present invention, and the technical scope of the present invention is not limited to the illustrated embodiments.

[0014] FIGS. 1 to 3 show an embodiment of the adhesion structure of the adhesive tape (hereinafter referred to as the adhesion structure). The adhesion structure 1 of the present embodiment includes an adhesive tape roll 11, a front roll 12 disposed in front of the adhesive tape roll 11, and a rear roll 13 disposed behind the adhesive tape roll 11.

[0015] As shown in FIG. 1, the rotating surface of the adhesive tape roll 11 and the rotating surface of the front roll 12 are arranged to be in contact with each other. Similarly, the rotating surface of the adhesive tape roll 11 and the rotating surface of the rear roll 13 are arranged to be in contact with each other. In this specification, the rotating surface refers to the side surface of a cylinder or a column that constitutes a roll or an adhesive tape roll.

[0016] The adhesive tape roll 11 is formed by winding an adhesive tape in a roll shape such that an adhesive surface is disposed on the surface on the inner side of the roll (referred to as the inner surface). In the adhesion structure of the present embodiment, as the adhesive tape roll 11, a roll of an adhesive tape wound around a cylindrical core material 111 provided with a release layer on the surface is used. The core material is not limited to a cylindrical shape, and may be, for example, a columnar shape. The release layer on the surface may be omitted. By using the core material, it becomes possible to feed out the adhesive tape to the end. Further, by using the core material, it becomes possible to stably feed out the adhesive tape even when the remaining amount of the adhesive tape decreases.

[0017] In the sticking structure 1 of the present embodiment, as shown in FIG. 3, as the front roll 12, a roll with a width (W3) of the front roll 12 larger than the width (W2) of the adhesive tape roll 11 is used. By this, it is possible to suppress the occurrence of wrinkles at the left and right ends of the adhesive tape 1112 and stick the adhesive tape neatly. The width of the front roll and the width of the adhesive tape roll may be configured to be equal.

[0018] In the sticking structure 1 of the present embodiment, as shown in FIG. 4, as the rear roll 13, a cylindrical member having washers 131 attached to the left and right ends and a bearing holder 132 is used. The rear roll 13 is supported in a rotatable state by a support portion 14.

[0019] The support portion 14 has a first portion 141 extending along the extending direction of the rear roll 13 and second portions 142 protruding from the left and right ends of the first portion 141. A rotating shaft 143 is inserted through the second portion 142 and the bearing holder 132. Thereby, the support portion 14 and the rear roll 13 are connected in a rotatable state. A bearing (not shown) is built in the bearing holder 132, and the rotating shaft 143 is connected to the rear roll 13 via the bearing. A rod-shaped grip portion 15 is connected to the middle of the first portion 141. The user can rotate the rear roll 13 by pushing the grip portion 15 by hand.

[0020] In the sticking structure 1 of this embodiment, an adhesive tape roll 11 is arranged on an object to which the adhesive tape is to be stuck, a front roll 12 is arranged in front of the adhesive tape roll 11, and a rear roll 13 is arranged behind the adhesive tape roll 11. As shown in FIG. 2, the adhesive tape 112 is pulled out from the adhesive tape roll 11. The pulled-out adhesive tape 112 is wound around the front roll 12 so as to be drawn under the front roll through above and the side surface of the front roll. In the adhesive tape roll 11, as shown in FIG. 5, an adhesive surface is arranged on the inner surface of the adhesive tape roll. The adhesive tape 112 is wound around the front roll 12 so that its adhesive surface is turned in a direction facing the object to which the adhesive tape is to be stuck.

[0021] As shown in FIG. 1, by pushing the gripping part 15 forward, the rear roll 13 is pushed forward. The adhesive tape roll 11 is pushed by the rear roll 13 and rotates in the reverse direction. The rear roll 13 and the front roll 12 rotate in the forward direction as the adhesive tape roll 11 rotates. The adhesive tape 112 is sequentially fed out by the rotational movement of the front roll 12 and is stuck to the object 2 while being drawn into the front roll 12. By passing the front roll 12, the adhesive tape roll 11, or the rear roll 13 over the adhesive tape 112 stuck to the object 2, the adhesive tape 112 is pressed against the object 2, and the object 2 and the adhesive tape are brought into close contact.

[0022] In the sticking structure 1 of this embodiment, as shown in FIG. 5, as the adhesive tape 112, an adhesive layer 113 is provided in a streak shape along the direction in which the adhesive tape 112 is fed out. In this configuration, compared with the configuration in which the adhesive layer is provided on the entire surface of the adhesive tape, the resistance when feeding out the adhesive tape can be reduced. As a result, the adhesive tape is fed out smoothly.

[0023] Wide adhesive layers 113 are provided at both ends of the adhesive tape 112 along the feeding direction of the adhesive tape, as compared with the adhesive layer 113 arranged in the middle. With this configuration, the ends of the adhesive tape are configured to be difficult to peel off.

[0024] In the sticking structure 1 of the present embodiment, the ratio of the outer diameter of the front roll (H3 in FIG. 1) to the outer diameter of the adhesive tape roll 11 (H2 in FIG. 1) is 50% or more and 150% or less, and the ratio of the outer diameter of the rear roll (H1 in FIG. 1) to the outer diameter of the adhesive tape (H2 in FIG. 1) is 50% or more and 200% or less. With this configuration, it is possible to prevent the adhesive tape roll 11 from riding on the front roll 12, the adhesive tape roll 11 from slipping under the front roll 12, the rear roll 13 from riding on the adhesive tape roll 11, and the rear roll 13 from slipping under the adhesive tape roll 11, and smoothly stick the adhesive tape (curing tape) to the object 2. Note that the outer diameter of the adhesive tape roll changes as the adhesive tape is paid out. The ratio of the outer diameter of the front roll to the outer diameter of the adhesive tape roll and the ratio of the outer diameter of the rear roll to the outer diameter of the adhesive tape roll, obtained based on the outer diameter when the adhesive tape roll is first arranged and the outer diameter when all the adhesive tape rolls are paid out, may be within the above ranges.

[0025] More preferably, the ratio of the outer diameter of the rear roll to the outer diameter of the adhesive tape roll is 70% or more and 190% or less. More preferably, the ratio of the outer diameter of the front roll to the outer diameter of the adhesive tape is 70% or more and 140% or less.

[0026] The front roll may be a cylindrical or columnar member configured to be equal to the width of the adhesive tape roll or larger than the width of the adhesive tape roll as described above. As the front roll, for example, a solid rod or cylinder made of any material such as plastic, paper, or metal can be used. For example, a plastic pipe having a smooth rotating surface at the construction site, another adhesive tape roll, etc. can be used as the front roll. It is preferable to use the materials available at the construction site as the front roll because the amount of materials carried into the construction site can be reduced.

[0027] The width and material of the rear roll are not particularly limited. The rear roll can be made of any material such as plastic, paper, metal, etc. In the adhesive structure 1 of the above embodiment, as shown in FIG. 3, a rear roll 13 with a width (W1) larger than the width (W2) of the adhesive tape roll 11 is used. The width (W1) of the rear roll may be, for example, the same as the width (W2) of the adhesive tape roll, or may be smaller than the width (W2) of the adhesive tape roll.

[0028] The shapes of the rear roll, the support part, or the gripping part are not limited to the examples of the above embodiment. The rear roll, the support part, or the gripping part may have, for example, the configuration shown in FIG. 6. In the example of FIG. 6, the rear roll 13b has a first roll 131b and a second roll 132b. The first roll 131b and the second roll 132b are cylindrical members, and each is provided with a bearing 133b at its left and right ends. The bearing 133b is arranged on the inner peripheral surface of the cylinder.

[0029] A rod-shaped support part 14b is inserted and fixed to the first roll 131b and the second roll 132b. There is a gap between the first roll 131b and the second roll 132b, and the rod-shaped support part 14b is in an exposed state. A rod-shaped gripping part 15b is connected to the middle of the rod-shaped support part.

[0030] The support part only needs to be configured to support the rear roll in a rotatable state, and it may have a configuration different from the examples shown in FIGS. 4 and 6. Also, components such as bearings can be omitted, and a simple configuration such as fitting a rotating shaft into a hole may be used. The gripping part is not limited to the examples in FIGS. 4 and 6, and any structure that allows the user to grip it by hand and operate the rear roll is acceptable. The configuration of the rear roll is not limited to the examples in FIGS. 4 or 6, and any structure with a cylindrical or columnar roll is acceptable.

[0031] The adhesive tape fed out from the adhesive tape roll is not limited to the example in FIG. 5, and the adhesive may be provided on the entire pasting surface of the adhesive tape.

[0032] Hereinafter, embodiments of the present invention will be specifically described with examples. Each of the embodiments shown below is merely an example of the present invention, and the technical scope of the present invention is not limited to the illustrated embodiments.

[0033] [Embodiment 1] As the adhesive tape, as shown in Table 1, an adhesive tape roll with an outer diameter of 110 mm, a tape width of 900 mm, and an adhesive layer disposed inside the adhesive tape roll was used. The adhesive tape roll used was one provided with a cylindrical core material. On the adhesive tape, a strip-shaped adhesive layer is formed along the feeding direction of the adhesive tape. At both ends of the adhesive tape, an adhesive layer with a width of 50 mm is provided, and in the middle of the attaching tape, an adhesive layer with a width of 2 mm is provided. The adhesive layer is formed by applying an acrylic-based adhesive.

[0034] As the rear roll, one having a gripping portion, a support portion, and a rear roll shown in FIG. ④ was used. The outer diameter of the rear roll is 110 mm as described in Table 1, and the width of the rear roll is 900 mm. The material of the rear roll is monomer cast nylon.

[0035] As the front roll, as described in Table 1, a cylindrical tube made of polyvinyl chloride with an outer diameter of 110 mm and a width of 900 mm was used. Note that the numerical values (%) shown in parentheses in Table 1 indicate the ratio (A) of the outer diameter of the rear roll to the outer diameter of the adhesive tape roll and the ratio (B) of the outer diameter of the front roll to the outer diameter of the adhesive tape roll. Specifically, each ratio was obtained as follows. The outer diameter of the adhesive tape roll was taken as the initial value when the tape was not being fed out. Ratio (A) (%) = Outer diameter of rear roll ÷ Outer diameter of adhesive tape roll × 100 Ratio (B) (%) = Outer diameter of front roll ÷ Outer diameter of adhesive tape roll × 100

[0036] As shown in Fig. 1, the front roll, the adhesive tape roll, and the rear roll were arranged in the order described from the front so that their respective rotating surfaces were in contact. The adhesive tape was fed out from the adhesive tape roll and wound around the front roll so that the adhesive tape reached downward after passing over and along the side of the front roll. In this state, the rear roll was pushed forward to perform the operation of attaching the adhesive tape (curing tape) to the floor surface.

[0037] [Example 2] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the front roll was changed to 82 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0038] [Example 3] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the rear roll was changed to 82 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0039] [Example 4] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the adhesive tape roll was changed to 90 mm as described in Table 1 and the outer diameter of the front roll was changed to 125 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0040] [Example 5] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the rear roll was changed to 200 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0041] [Comparative Example 1] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the front roll was changed to 33 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0042] [Comparative Example 2] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the rear roll was changed to 33 mm as described in Table 1, and the operation of attaching the adhesive tape was performed.

[0043] [Comparative Example 3] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the front roll was changed to 200 mm as described in Table 1, and an operation of attaching the adhesive tape was performed.

[0044] [Comparative Example 4] A sticking structure was constructed in the same manner as in Example 1 except that the outer diameter of the rear roll was changed to 300 mm as described in Table 1, and an operation of attaching the adhesive tape was performed.

[0045] [Comparative Example 5] A sticking structure was constructed in the same manner as in Example 1 except that the width of the front roll was changed to 600 mm as described in Table 1, and an operation of attaching the adhesive tape was performed.

[0046]

Table 1

[0047] Using the attachment structures of Examples 1 to 5 and Comparative Examples 1 to 5, when performing the operation of attaching the adhesive tape (curing tape), wrinkles were formed on the adhesive tape, and the adhesive tape could be smoothly attached to the floor surface without disturbing the positional relationship among the front roll, the adhesive tape roll, and the rear roll. In the attachment structure of Comparative Example 1, the adhesive tape roll climbed onto the front roll. As a result, the normal rotation of each roll and the adhesive tape roll was hindered. At that time, the adhesive layers of the adhesive tape adhered to each other, and it took time to correct. In the attachment structure of Comparative Example 2, the rear roll got under the adhesive tape roll, and the adhesive tape roll was lifted up. As a result, the normal rotation of each roll and the adhesive tape roll was hindered. At that time, the adhesive layers of the adhesive tape adhered to each other, and it took time to correct. In the attachment structure of Comparative Example 3, the adhesive tape was pulled upward by the front roll, and the rear roll got under the adhesive tape roll. As a result, the normal rotation of each roll and the adhesive tape roll was hindered. In the attachment structure of Comparative Example 4, since the rear roll climbed over the tape roll, the adhesive tape roll could not be normally pushed. In the attachment structure according to Comparative Example 5, since the left and right ends of the fed adhesive tape did not contact the front roll, the adhesive tape was attached to the floor surface with wrinkles generated at the left and right ends of the adhesive tape.

[0048] As described above, with the attachment structures of Examples 1 to 5, it is possible to neatly attach the adhesive tape (curing tape) to the floor surface as the object with a simple structure. In the above examples, the floor surface was taken as an example of the object, but the adhesive tape can be similarly attached to objects other than the floor surface.
