Description

[[Technical Field]]

[0001] The present disclosure relates to a tape cutter that deforms and cuts a tape. [[Background Art]]

[0002] In order to improve the airtightness of a building, a tape is sometimes adhered and sealed to the abutting portion between members. In such cases, it is preferable to adhere the tape without gaps or lifting, but when the abutting portion has an angle such as an internal corner, or when the portion to be adhered is small, it is difficult to insert a hand and achieve close adhesion in some cases. For this reason, there have been problems that the work of adhering the tape takes time, and the airtightness varies depending on the skill of the operator. In addition, if there is a gap or lifting between the adhered tape and the internal corner, there is a risk that the tape may be broken by a member constructed after the tape is adhered, or the mounting accuracy of the member may be affected.

[0003] For example, Patent Document 1 proposes a tape applying machine provided with a V-shaped rotating roller and a V-shaped pressure-bonding guide, which facilitates applying an adhesive tape to an internal corner. [[Prior Art Document]] [[Patent Document]]

[0004] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2002-87692 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] In the tape applying machine disclosed in Patent Document 1, the degree of close adhesion of the tape to the internal corner changes depending on the angle formed by the V-shape of the V-shaped rotating roller and the V-shaped pressure-bonding guide, and it is considered difficult to press the entire tape and adhere it in an airtight manner in a right-angled internal corner or the like.

[0006] This disclosure has been made in view of the circumstances described above, and its purpose is to provide a tape cutter that enables the precise and easy application of tapes requiring adhesion, regardless of the operator's skill level. [Means for solving the problem]

[0007] To solve the aforementioned problems, the tape cutter of the present disclosure is a tape cutter that cuts a tape having an adhesive surface on its back surface while it is folded along the stretching direction, and comprises a main body portion having a tape holding portion that detachably and rotatably holds an annular tape body in which the tape is wound in a ring shape, a pressing member supported by the main body portion that presses the tape pulled out from the annular tape body from the surface side, a blade portion provided on the pressing member, and an operating portion for operating the pressing member, wherein the pressing member is made of a pair of flat plate members that are rotatably connected to each other via a rotating portion, the rotating portion is provided with the stretching direction of the tape as its axial direction, and the pressing member rotates by operation of the operating portion, making it possible to fold the tape.

[0008] Furthermore, in the tape cutter described above, it is preferable that the pressing member is bent and deformed by the operating part into a mountain shape that is convex outward or a valley shape that is convex inward relative to the main body, thereby bending and deforming the tape pulled out from the annular tape body into a bi-fold shape along the stretching direction.

[0009] Furthermore, in the tape cutter described above, the pressing member may be deformable into a flat plate shape in which the angle formed by a pair of the flat plate members around the rotating part is a flat angle, and into a bent shape in which the angle formed by a pair of the flat plate members is not a flat angle when rotated around the rotating part.

[0010] Furthermore, in the tape cutter described above, it is preferable that the pressing member is supported by the main body via a link mechanism, and the operating unit rotates a pair of flat plate members around the rotating part to deform the pair of flat plate members relative to the main body.

[0011] Furthermore, in the tape cutter described above, the pressing member preferably includes, as the link mechanism, a first link with one end rotatably connected to one of a pair of flat plate members, and a second link with one end rotatably connected to the other, the other end of the first link and the other end of the second link rotatably connected to the main body, and the operating part preferably displaces the rotating part in a front-rear direction perpendicular to the extension direction via a slider connected to the rotating part.

[0012] Furthermore, in the tape cutter described above, it is preferable that the operating unit comprises an operating lever that is manually operated in the forward and backward directions, and a transmission mechanism connected to the operating lever and the slider that transmits the movement of the operating lever to the slider, and that the slider slides in the forward and backward directions in conjunction with the operation of the operating lever.

[0013] Furthermore, in the tape cutter described above, it is preferable that the operating lever is provided on the main body on the side opposite to the direction in which the tape is pulled out from the tape holding part, the tape is pulled out with the front-to-back direction as the pulling direction, and is guided in the stretching direction against the pressing member via a guide provided on the main body. [Effects of the Invention]

[0014] According to this disclosure, it becomes possible to apply tapes requiring adhesion accurately and easily, regardless of the worker's skill level. [Brief explanation of the drawing]

[Figure 8] It is a perspective view showing said tape cutter. [Figure 9] It is an explanatory view showing an example of an internal corner of a building. [Mode for Carrying Out the Invention]

[0016] A tape cutter according to an embodiment of the present disclosure will be described with reference to the drawings.

[0017] (Embodiment 1) Figs. 1 to 5 are perspective views showing a tape cutter 1 according to the first embodiment of the present disclosure. In Figs. 1 to 3, in the tape cutter 1, a pressing member 20, which will be described later, is shown in a flat plate shape, and Figs. 4 and 5 show an example of a state where the pressing member 20 has a bent shape. Note that the arrow direction X shown in the drawings indicates the longitudinal direction of the tape T drawn out from the annular tape body T1 and the longitudinal direction of the main body 10, and is described as the front-rear direction X in the tape cutter 1, but this does not limit the usage mode of the tape cutter 1.

[0018] A tape cutter 1 is used for cutting a tape T having an adhesive surface on the back surface to a desired length and applying the cut tape, and is particularly configured to be capable of cutting the tape T in a state of being bent along the longitudinal direction of the tape T. For example, as shown in FIG. 9, when constructing an interior material such as a gypsum board on a heat insulating material 92 disposed on the indoor side of an outer wall material 91 of a building, an operation of attaching a tape T such as an airtight tape to an internal corner 90 formed by the heat insulating material 92 to ensure airtightness is performed. In such a case, the tape T is preferably attached in a state of being bent into an L-shape so as to be in close contact with the internal corner 90, and the tape cutter 1 can be suitably used.

[0019] As shown in FIG. 1, the tape cutter 1 has a main body portion 10. The main body portion 10 is provided with a tape holding portion 13 that detachably and rotatably holds an annular tape body T1 formed by winding the tape T in an annular shape. The tape holding portion 13 protrudes from one surface of the main body portion 10 and is formed in a cylindrical shape onto which the annular tape body T1 can be externally fitted.

[0020] The tape T is pulled out from the annular tape body T1 on the tape holding portion 13 to the X1 side. The pulled-out tape T is guided to the pressing member 20 via the lower edge portion of the guide plate 11 of the main body portion 10 and the rod-shaped first guide 121. That is, the tape T is guided in a stretching direction Y orthogonal to the front-rear direction X via the guide plate 11 and the first guide 121 provided on the main body portion 10. Above the first guide 121, a second guide 122 is provided with the pressing member 20 interposed therebetween. The leading end of the tape T can be adhesively held, for example, on the upper end of the pressing member 20 by utilizing the adhesiveness of the back surface of the tape T.

[0021] The pressing member 20 is provided at an end portion on the X1 side, which is one end portion of the main body portion 10 in the front-rear direction X. The pressing member 20 is supported by the main body portion 10 and is provided as a portion that presses the tape T pulled out from the annular tape body T1 from the front surface side.

[0022] In the exemplary embodiment, the pressing member 20 includes a pair of flat plate members 21a and 21b, a rotating portion 23, a blade portion 22, and a link mechanism 24. The pair of flat plate members 21a and 21b are rotatably connected to each other via the rotating portion 23. The rotating portion 23 is provided with the extension direction Y of the tape T as its axial direction. The pressing member 20 is provided with a blade portion 22 for cutting the tape T along the upper edges of the pair of flat plate members 21a and 21b.

[0023] The pressing member 20 is supported by the main body 10 via a link mechanism 24. As shown in Figures 1 and 2, a support member 16 extends from one side of the guide plate 11 (the X1 side) along the X1 direction to the main body 10. The pressing member 20 includes a link mechanism 24 consisting of a first link 241, one end of which is rotatably connected to one flat plate member 21a, and a second link 242, one end of which is rotatably connected to the other flat plate member 21b. The other end of the first link 241 and the other end of the second link 242 are rotatably connected to the tip of the support member 16 extending from the guide plate 11.

[0024] As the rotating part 23 moves in the front-rear direction X, a pair of flat plate members 21a and 21b rotate around the rotating part 23 and bend into a folded shape, as shown in Figures 4 and 5. The angle between one flat plate member 21a and the first link 241, and the angle between the other flat plate member 21b and the second link 242 are widened.

[0025] In the example configuration, the pressing member 20 is bent and deformed into an outwardly convex mountain shape relative to the X1 end of the main body 10, and the tape T pulled out from the annular tape body T1 is bent and deformed into a fold in half along the stretching direction Y.

[0026] The pressing member 20 is operated via the operating section 30. The operating section 30 is located at the X2 side end, which is the other end of the main body 10 in the front-rear direction X. The operating section 30 includes an operating lever 31. The operating lever 31 is located on the opposite side of the X1 direction, which is the direction in which the tape T is pulled out from the annular tape body T1 of the tape holding section 13.

[0027] The operating lever 31 is held by being spanned between a slide hole 101 in the main body 10 and a slide hole 141 in the support portion 14 extending from the main body 10. These slide holes 101 and 141 are formed to be elongated in the front-rear direction X. The operating lever 31 is provided to be slidable in the front-rear direction X along the slide holes 101 and 141.

[0028] As shown in Figure 3, in the tape cutter 1, an arm portion 32 is connected to an operating lever 31 as the operating section 30. The arm portion 32 extends long in the front-rear direction X and is arranged along the surface of the main body portion 10 opposite to the surface on which the tape holding portion 13 is projected. One end of the arm portion 32 is connected to the operating lever 31, and the other end is connected to the transmission mechanism portion 35. The main body portion 10 is provided with a first slit 151 and a second slit 152 that are long in the front-rear direction X. The transmission mechanism portion 35 is provided to transmit the movement of the operating section 30 to the pressing member 20.

[0029] In the operating section 30, the flat plate members 21a and 21b are rotated around the rotating section 23 to deform the flat plate members 21a and 21b relative to the main body 10. Connecting sections 34, which are connected to sliders 33, are connected to both ends of the rotating section 23. The sliders 33 extend through the guide plate 11 to both the front and back surfaces of the guide plate 11 and are slidable along the front-rear direction X.

[0030] The connecting portion 34 is disposed between a pair of flat plate members 21a and 21b and the guide plate 11. In the exemplary configuration, the connecting portion 34 has a roughly U-shape, and both ends are connected to the axial ends of the rotating portion 23, respectively. As shown in Figure 2, the connecting portion 34 is equipped with a connecting portion 341 that extends in the extension direction Y. The connecting portion 341 is disposed on the X1 side of the guide plate 11. The slider 33, which penetrates the guide plate 11, has its tip protruding on the X1 side of the guide plate 11 and is connected to the connecting portion 341. When the slider 33 slides in the front-rear direction X, the connecting portion 34 slides in the front-rear direction X via the connecting portion 341 in conjunction with it.

[0031] In the tape cutter 1 according to the exemplary embodiment, as shown in Figure 1, the transmission mechanism 35 includes a first rack 351 provided at the other end of the arm portion 32, a second rack 352 provided on the slider 33, and a pinion 353 that engages with the first rack 351 and the second rack 352. The first rack 351 is disposed inside the main body portion 10 through the first slit 151 of the main body portion 10. The first rack 351 and the second rack 352 are provided as long sections along the front-rear direction X and are arranged parallel to each other. The pinion 353 is rotatably supported on a rotating shaft 171 on a support portion 17 that extends from the guide plate 11 of the main body portion 10 toward the X2 side.

[0032] The operating lever 31 is manually operated in the forward / backward direction X. When the operating lever 31 is moved in the X2 direction along the slide holes 101 and 141, the first rack 351 slides in the X2 direction together with the arm portion 32 connected to the operating lever 31. In conjunction with this, the second rack 352 slides in the X1 direction via the pinion 353. The slider 33 slides in the X1 direction together with the second rack 352.

[0033] Therefore, the slider 33 can slide in the forward / backward direction X in conjunction with the operation of the operating lever 31. When the slider 33 slides in the X1 direction, it presses the connecting portion 341 in the X1 direction. The sliding of the connecting portion 34 in the X1 direction displaces the rotating portion 23 of the pressing member 20 in the X1 direction. The transmission mechanism 35 converts the forward / backward movement X of the operating lever 31 and the arm portion 32 into parallel movement in the opposite direction X of the slider 33 and the connecting portion 34 and transmits it.

[0034] As a result, a pair of flat plate members 21a and 21b in the pressing member 20 rotate around the rotating part 23. The pressing member 20 deforms from a flat plate shape where the angle between the pair of flat plate members 21a and 21b is a flat angle to a bent shape where the angle between the pair of flat plate members 21a and 21b is not a flat angle. In the bent shape, the angle between the pair of flat plate members 21a and 21b can be, for example, an acute angle, a right angle, or an obtuse angle.

[0035] At the construction site, the annular tape body T1 is fitted into the tape holding part 13 of the tape cutter 1, and the tape T is pulled out and set on the pressing member 20 (see Figures 1 and 2). The tape T is extended along the X1 side surface of the pressing member 20. By pulling the operating lever 31 in the X2 direction, the pressing member 20 deforms from a flat shape to a bent shape (see Figures 4 and 5).

[0036] As a result, the surface of the tape T is pressed, creating a convex mountain shape outward relative to the main body 10, and is folded into a bi-fold shape along the stretching direction Y. By adjusting the bending angle of the pressing member 20 to match the angle of the inner corner of the object to be attached, the tape T can be made into a folded shape corresponding to the inner corner.

[0037] The tape T, which is bent in the direction of extension Y, can be attached to the inside corner of the workpiece by pressing it against the pressing member 20. Furthermore, by moving the main body 10 along the direction of extension Y, for example downwards in the figure, while bending and attaching the tape T in this way, the bent tape T can be attached to a desired length. After the tape T has been attached to the predetermined position, the tape T can be cut with the blade portion 22 of the pressing member 20.

[0038] In this way, by using the tape cutter 1 to apply the tape T, it becomes possible to apply the tape T, which requires adhesion, with precision and ease, regardless of the worker's skill level.

[0039] (Embodiment 2) In the tape cutter 1 of this disclosure, the transmission mechanism 35 that transmits the operation of the operating unit 30 is not limited to the configuration shown in Embodiment 1, but can have various other configurations.

[0040] Figure 6 is a plan view showing the tape cutter 1 according to Embodiment 2, and Figures 7 and 8 are perspective views showing the tape cutter 1 according to Embodiment 2. The tape cutter 1 according to this embodiment has the same basic configuration as the one shown in Embodiment 1, and is characterized by the configuration of the transmission mechanism 36. The transmission mechanism 36 will be described in detail below, and other components will be given the same reference numerals as in Embodiment 1 and detailed descriptions will be omitted.

[0041] In this configuration, the tape cutter 1 includes a transmission mechanism 36 comprising a first link 361, a second link 362, and a rotating plate 363. As shown in Figure 6, one end of the first link 361 is rotatably connected to the other end of the arm portion 32, and the other end is rotatably connected to the rotating plate 363. As shown in Figure 7, one end of the second link 362 is rotatably connected to the rotating plate 363, and the other end is rotatably connected to the slider 37.

[0042] A support member 18 extending in the front-rear direction X is provided on the guide plate 11 of the main body 10. The rotating plate 363 is rotatably supported via a rotation shaft 181 on the support member 18. In this case as well, the transmission mechanism 36 converts the movement of the operating lever 31 and the arm 32 in the front-rear direction X into parallel motion in the opposite direction X of the slider 37 and the connecting part 34 and transmits it.

[0043] The slide hole 142 of the operating lever 31 is provided to be long in the front-rear direction X, similar to the slide hole 101. The operating lever 31 is provided to be slidable in the front-rear direction X along the slide holes 101 and 142. Unlike the slide hole 141 in Embodiment 1, the slide hole 142 has an open shape at the top.

[0044] When the slider 37 slides in the X1 direction in conjunction with the operation of the operating lever 31, the connecting part 341 connected to the slider 37 is pressed in the X1 direction, causing the connecting part 34 to slide in the X1 direction and displace the rotating part 23 of the pressing member 20 in the X1 direction. The pressing member 20 deforms from a flat shape to a bent shape, allowing the tape T to be easily bent and attached in a shape that follows the inside corner.

[0045] Furthermore, the tape cutter 1 of this disclosure can be suitably used not only for the inner corners 90 of a building as shown in Figure 9, but also for the outer corners. In that case, it is preferable that the tape cutter 1 is configured such that, for example, the transmission mechanism 35 has a flat plate shape when in the state shown in Figure 1, and the pressing member 20 has a bent shape that is a convex mountain shape inward relative to the main body 10 when in the state shown in Figure 4. The angle between a pair of flat plate members 21a and 21b is a favorable angle of 180 degrees or more.

[0046] Furthermore, the tape cutter 1 can be suitably used when applying tape T to parts of a building that form an inner corner or outer corner, such as between an interior wall frame and a window frame, where surfaces are not continuous. By applying the tape T in a folded state, an inner corner or outer corner can be formed, and then insulation material or interior material can be applied to the interior side of the tape T.

All technical matters included in the technical idea described in the claims are subject to this disclosure.
