Description

[Technical Field]

[0001] The present invention relates to a transfer tool. [Background technology]

[0002] Conventionally, a transfer device has been known that includes a supply reel from which a transfer tape having a transfer material such as glue attached thereto is supplied, a take-up reel for taking up the transfer tape supplied from the supply reel, and a reel linkage mechanism that links the rotation of the supply reel and the take-up reel (see, for example, Patent Document 1).

[0003] Some transfer tools of this type have a clutch provided between a payout gear supported on a common shaft and a payout reel in order to optimize the tension of the transfer tape.

[0004] Conventional clutches are configured so that one member (e.g., a payout reel) slides against the other member (e.g., a payout gear) while making surface contact in a direction intersecting the axis of the common shaft.

[0005] However, with such a configuration, due to minute variations in the molded products (such as minute dimensional differences in the molded products), individual differences in the torque value at which the clutch can operate are likely to occur for each transfer tool.

[0006] In particular, when the transfer tool is used to transfer a thin film of correction agent, the operation of running the transfer tape is performed with a relatively light force, so if there is variation in the torque value at which the clutch can operate for each transfer tool, it may impair the user's comfortable use experience.

[0022] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0023] In this embodiment, the present invention is applied to a transfer tool for transferring a thin film of correction agent (not shown) to a transfer target surface (not shown) such as paper. The transfer tool is configured so that transfer tape T is fed from a feed reel C, passes through a transfer head B, and is taken up by a take-up reel D.

[0024] The transfer tool is configured so that the correction agent can be transferred from the substrate t to the surface to be transferred by pressing the transfer tape T, which has a thin film of correction agent applied to one side of a belt-shaped substrate t, against the surface to be transferred by the tip pressing part P provided at the tip of the transfer head B, and flowing and running the transfer tape T from the upstream side (the side of the pay-out reel C) to the downstream side (the side of the take-up reel D).

[0025] The transfer tool comprises a case A capable of storing transfer tape T therein, a transfer head B disposed at the front end of case A, a supply reel C stored in case A and wound with transfer tape T holding a correction agent, a take-up reel D stored in case A for taking up the transfer tape T that is paid out from the supply reel C and passes through the tip pressing portion P of the transfer head B, and a reel interlocking mechanism E that interlocks the rotation of the supply reel C and the take-up reel D.

[0026] The reel linkage mechanism E in this embodiment is provided with a slip clutch S for causing slippage between the payout gear M, which is a first rotating member that rotates around the first support axis j1, which is a common axis provided in the case A, and the payout reel C, which is a second rotating member, thereby optimizing the degree of tension of the transfer tape T.

[0027] Each component of the transfer tool will be described below.

[0028] <Case A> Case A is made of synthetic resin and has an internal storage space sp that can accommodate supply reel C, take-up reel D, and reel interlocking mechanism E.

[0031] In addition, in FIG. 4, for the convenience of explaining the internal structure of the transfer tool, the right case member K is shown removed.

[0032] A first support shaft j1 for rotatably supporting a payout reel C and a payout gear M that constitute a reel interlocking mechanism E is provided to protrude from the inner surface of the left side wall 1.

[0033] A second support shaft j2 protrudes from the inner surface of the left side wall 1 and rotatably supports the winding reel D and winding gear N that constitute the reel interlocking mechanism E. The second support shaft j2 is disposed in front of the first support shaft j1.

[0034] A third support shaft j3 protrudes from the inner surface of the left side wall 1 and rotatably supports an intermediate gear L that constitutes the reel interlocking mechanism E. The third support shaft j3 is disposed between the first support shaft j1 and the second support shaft j2. A claw-shaped retaining portion j31 is provided at the tip of the third support shaft j3 to prevent the intermediate gear L from coming off.

[0035] On the inner surface of the left side wall 1, first and second tape guide portions i1 and i2 are erected, each having a substantially cylindrical shape and guiding the tape trajectory of the transfer tape T led out from the payout reel C.

[0036] The case A is provided with a protective cover F which is supported rotatably between a covering position (H) where the transfer head B can be covered and a retracted position (I) where the transfer head B is retracted.

[0037] <Transfer head B> The transfer head B comprises a frame body b1 integrally formed from synthetic resin, and a plate-shaped body b2 having a tip pressing portion P at its front end that presses the transfer tape T against the surface to be transferred.

[0038] The frame body b1 is attached to the case A. The frame body b1 includes left and right upright walls b11 that are wall-shaped and extend in the front-to-rear and up-down directions and are arranged in pairs on the left and right, horizontal sections b12 that extend in the left-to-right direction and connect the left and right upright walls b11, and case connection sections b13 that are connected rearward from the rear ends of the left and right upright walls b11 and connect to the case A.

[0039] The plate-shaped body b2 is supported by the frame body b1. The plate-shaped body b2 is made of metal and has a generally horizontal plate shape extending in the front-rear direction. A tip pressing portion P is formed at the tip of the plate-shaped body b2, extending in the left-right direction and contacting the other surface of the base material t of the transfer tape T, to press the correction agent attached to the transfer tape T against the transfer target surface.

[0040] <Payment reel C> The payout reel C constitutes the reel interlocking mechanism E. In this embodiment, the payout reel C has a payout reel body c1 which is a cylindrical portion around which the transfer tape T is wound, and a protrusion c3 which constitutes a pressing portion capable of pressing the elastic displacement portion Q is integrally provided on the inside of the payout reel body c1. The protrusion c3 has a flange shape which extends inward from the payout reel body c1.

[0041] In more detail, the payout reel C comprises a cylindrical payout reel main body c1 extending in the left-right direction and having transfer tape T wound around its outer periphery, a side plate c2 provided in a flange-like shape on one side of the payout reel main body c1, and a flange-like protrusion c3 protruding inward, i.e., toward the center of rotation, from the inner peripheral surface of the payout reel main body c1.

[0042] The inner end of the protrusion c3 is formed with a pointed portion v, which is a point-like contact portion whose tip is sharpened at an angle of approximately 90°. As shown in Fig. 9, the pointed portion v is formed at a position shifted outward from the center in the left-right direction, i.e., toward the side plate portion c2.

[0043] The payout reel C is rotatably supported by a first support shaft j1 that protrudes from the case A via a payout gear M.

[0044] <Take-up reel D> The take-up reel D takes up the transfer tape T that has been fed from the supply reel C via the tip pressing portion P of the transfer head B. The take-up reel D has a roughly cylindrical take-up reel body portion d1 that extends in the left-right direction and is capable of taking up the transfer tape T on its outer periphery, and left and right flange portions d2 provided on both left and right ends of the take-up reel body portion d1. The take-up reel D is rotatably supported on a second support shaft j2 that protrudes from the case A.

[0045] <Reel Linkage Mechanism E> The reel interlocking mechanism E is configured to include a payout reel C around which is wound the transfer tape T before transfer and which retains the correcting agent, a payout gear M that is rotatably supported on the first support shaft j1 and can rotate together with the payout reel C, an intermediate gear L that is rotatably supported on the third support shaft j3 and meshes with the payout gear M, a take-up gear N that is rotatably supported on the second support shaft j2 and meshes with the intermediate gear L, and a take-up reel D that is integrally provided on the side of the take-up gear N and that takes up the transfer tape T after transfer from which the correcting agent has been released.

[0046] The payout gear M comprises a payout gear main body m1 having a shaft hole in the center into which the first support shaft j1 is inserted and having a plurality of teeth ha arranged on its annular outer periphery that mesh with the intermediate gear L, and a payout reel support shaft m2 that stands upright from the center of the payout gear main body m1 so as to surround the first support shaft j1 and is inserted into the center hole of the payout reel C. The payout gear main body m1 and the payout reel support shaft m2 are integrally formed from synthetic resin.

[0047] The payout reel support shaft m2 comprises a base end cylindrical portion m21 rising from the payout gear main body portion m1, an inner flange portion m22 extending inward from the tip of the base end cylindrical portion m21, a central cylindrical portion m23 rising from the extending end of the inner flange portion m22 along the axis cn of the first support shaft j1, and a plurality of elastic displacement portions Q extending in a cantilevered manner from the tip of the central cylindrical portion m23.

[0048] Like the base end cylindrical portion m21 and the central cylindrical portion m23, the elastically deformable portion Q extends along the axis cn of the first support shaft j1. A plurality of elastically deformable portions Q, i.e., four elastically deformable portions Q, are arranged at regular intervals so as to surround the axis cn of the first support shaft j1. In other words, slits R are provided between the four elastically deformable portions Q, extending along the axis cn of the first support shaft j1 and allowing elastic deformation of the elastically deformable portions Q. A pressed surface U is provided on the outer surface of the elastically deformable portion Q, which is pressed by a protrusion c3 provided on the payout reel C.

[0049] A tip-side raised portion q1, which is provided at the tip end and proximal raised portion q2, which is provided at the proximal end and also protrudes like a mountain, is provided side by side on the outer surface of the elastically deformable portion Q. A recessed portion q3 is formed between the tip-side raised portion q1 and the proximal raised portion q2. The pressed surface U, which contacts the pointed portion v, which is a point contact portion of the protrusion c3, is provided in an area of ​​the tip-side raised portion q1 facing the recessed portion q3.

[0050] In this embodiment, a position regulating portion W is provided to position the payout reel C relative to the payout gear M. The position regulating portion W includes a reel-side contact end surface c11 provided on the left edge, which is one edge of the payout reel main body c1, and a gear-side contact surface m11 that is annularly provided in the vicinity of the payout reel support shaft m2 on the payout gear main body m1 and that can come into contact with the reel-side contact end surface c11.

[0051] The winding gear N has a plurality of teeth ha on its outer periphery that mesh with the intermediate gear L. The winding gear N is integrally provided on the winding reel D with its axis aligned with that of the winding reel D.

[0052] <Slip clutch S> The slip clutch S allows relative rotation between the payout gear M and the payout reel C when a certain level of tension or more is generated in the transfer tape T, in order to optimize the degree of tension in the transfer tape T stretched between the payout reel C and the take-up reel D.

[0053] The slip clutch S includes an elastic displacement portion Q provided on the payout gear M and configured to be elastically displaceable in a direction intersecting the axis cn of the first support shaft j1, and a protrusion c3 provided on the payout reel C and capable of pressing the elastic displacement portion Q.

[0054] 9, the elastically deformable portion Q is provided with a pressed surface U with which the protrusion c3 comes into point contact in a cross-sectional view of the first support shaft j1 in the direction of the axis cn. The pressed surface U is inclined with respect to the axis cn of the common shaft.

[0055] The protruding end of the protruding portion c3 is provided with a pointed portion v which serves as a point contact portion that makes point contact with the pressed surface U formed on the elastically deformable portion Q in a cross-sectional view taken along the axis cn of the first support shaft j1.

[0056] Next, the operation of the slip clutch S in the transfer tool of this embodiment will be described.

[0057] In the transfer tool, when the transfer tape T backed by the transfer head B of the transfer head B is moved while in contact with the surface to be transferred, the transfer tape T is sequentially paid out from the payout reel C. At the same time, the rotational force of the payout reel C generated by the movement of the transfer tape T is transmitted to the take-up reel D by the reel interlocking mechanism E, so that the transfer tape T is taken up by the take-up reel D.

[0058] The rotational force of the supply reel C is transmitted to the supply gear M via the slip clutch S. Furthermore, the rotational force of the supply reel C is transmitted to the take-up reel D, which is integrally provided with the take-up gear N, via an intermediate gear L that meshes with the supply gear M. The take-up reel D then receives the rotational force and winds up the transfer tape T.

[0059] As the remaining amount of transfer tape T wound around the supply reel C decreases and the amount of transfer tape T wound around the take-up reel D increases, the rotation speed of the supply reel C increases and the rotation speed of the take-up reel D also increases. As a result, the tension, or degree of tension, of the transfer tape T between the take-up reel D and the supply reel C gradually increases. In addition, the rotational force transmitted from the supply reel C to the pay-out gear M also increases in proportion to the tension of the transfer tape T.

[0060] When this rotational force increases above a predetermined level, the rotational force of the payout reel C becomes greater than the frictional force between the payout reel C and the payout gear M, causing the payout reel C to slide in the rotational direction relative to the payout gear M. In other words, the payout reel C rotates faster in the rotational direction than the payout gear M.

[0061] In this embodiment, a pointed portion v, which is a point contact portion formed on the protrusion c3 of the payout reel C, is in point contact with the pressed surface U of the elastic displacement portion Q of the payout gear M. This makes it possible to reduce as much as possible the contact area that rubs in a direction that intersects with the axis cn of the slip clutch S. This effectively prevents the problem of individual differences in the torque value of the slip clutch S due to variations in molded products, etc.

[0062] As described above in detail, the transfer tool according to this embodiment is configured so that the transfer tape T is fed from the feeding reel C, passes through the transfer head B, and is taken up by the take-up reel D.

[0063] The transfer device is equipped with a reel linkage mechanism E that links the rotation of the payout reel C and the take-up reel D, and a slip clutch S that constitutes this reel linkage mechanism E and causes slippage between the payout gear M, which is a first rotating member that rotates around the first support axis j1, which is a common axis, and the payout reel, which is a second rotating member, thereby optimizing the degree of tension of the transfer tape T.

[0064] The slip clutch S is provided with an elastic displacement portion Q that is provided on the payout gear M and configured to be elastically displaceable in a direction intersecting the axis cn of the first support shaft j1, and a protrusion c3 that is provided on the payout reel C and can press the elastic displacement portion Q.

[0065] The protruding portion c3 is provided with a pointed portion v as a point contact portion that comes into point contact with the pressed surface U formed on the elastically deformable portion Q in a cross section seen in the direction of the axis cn.

[0066] That is, the elastically deformable portion Q is provided with a pressed surface U with which the protruding portion c3 comes into point contact in a cross-sectional view taken along the axis cn.

[0067] Therefore, it is possible to provide a transfer tool in which the problem of individual differences in the torque value of the slip clutch S due to variations in the molded product, etc., is suitably suppressed.

[0068] In this embodiment, the point contact portion is a pointed portion v formed at the protruding end of the protrusion c3. Therefore, by forming the pointed portion v, variation in shape between products is effectively suppressed. Furthermore, by forming the point contact portion as the pointed portion v, it is possible to minimize the contact area that rubs in a direction intersecting the axis cn of the slip clutch S.

[0069] A position control section W is provided to position the payout reel C relative to the payout gear M, so that the pointed portion v of the payout reel C can properly contact the pressed surface U of the payout gear M, allowing the slip clutch S to function stably.

[0070] The pressed surface U is inclined with respect to the axis cn of the first support shaft j1, which is the common axis. Therefore, in cooperation with the position regulating portion W, the payout reel C is appropriately positioned with respect to the payout gear M.

[0071] The payout gear M, which is the first rotating member, has an elastic displacement portion Q integrally formed thereon, and the payout reel C, which is the second rotating member, has a cylindrical portion on which the transfer tape T is wound and has a protrusion c3 integrally formed on the inside of the cylindrical portion.

[0072] For this reason, the slip clutch S is suitably realized by the payout gear M and the payout reel C with a limited number of parts.

[0073] The payout gear M comprises a payout gear main body m1 having a plurality of teeth ha arranged in a row on its annular outer peripheral edge, and a plurality of elastic displacement parts Q extending along the axis cn of the common shaft and arranged at regular intervals so as to surround the axis cn.

[0074] Therefore, the elastic displacement portion Q is suitably disposed on the payout gear M.

[0075] The reel interlocking mechanism E comprises a payout reel C, a payout gear M having a slip clutch S interposed therebetween and capable of rotating together with the payout reel C, an intermediate gear L meshing with the payout gear M, a winding gear N meshing with the intermediate gear L, and a winding reel D capable of rotating together with the winding gear N.

[0076] Therefore, the rotational force of the supply reel C is suitably transmitted to the take-up reel D.

[0077] The transfer tape T is a correction tape comprising a belt-shaped substrate t and a correction agent applied to one side of the substrate t.

[0078] Therefore, even if the transfer operation is performed with a relatively light force, the desired purpose can be achieved.

[0079] The present invention is not limited to the above-described embodiment.

[0080] The transfer tool may be any tool that transfers the transfer material attached to the transfer tape to the transfer target. In other words, the transfer material is not limited to the thin film correction agent shown in this embodiment, but may also be, for example, a decorative material (decorative tape) or glue.

[0081] The first and second rotating members that rotate around a common axis are not limited to those shown in this embodiment.

[0082] For example, the first rotating member may be a payout reel and the second rotating member may be a payout gear.

[0083] Furthermore, one of the first rotating member and the second rotating member may be a take-up gear, and the other may be a take-up reel.

[0084] The first rotating member and the second rotating member may be separate members from the gear and reel that are interposed between the gear and reel that rotate around a common axis, for example, cylindrical members known as core members.

[0085] The pressing portion may have any suitable shape as long as it can press the elastically deformable portion so as to be elastically deformable.

[0086] For example, the part of the pressing portion that comes into contact with the elastic displacement portion may be configured as a flat surface (including the inner surface of a cylinder) with almost no unevenness, or may have a concave shape.

[0087] The protrusion is not limited to being provided on the pressing portion side as in the above-described embodiment, but may be provided on the elastically deformable portion side, for example.

[0088] It goes without saying that the shape of the protrusion is not limited to that in the above-described embodiment.

[0089] The pressed surface is not limited to that provided on the elastically deformable portion side as in the above-described embodiment, but may be, for example, that provided on the pressing portion side.

[0090] The point contact portion may have any shape that can contact the pressed surface in a point-like manner, and its specific shape may be set as appropriate. In other words, the point contact portion is not limited to the pointed portion shown in the above embodiment, and may have a rounded contact end.

[0091] The position regulating portion may be of any configuration as long as it is configured to position the second rotating member relative to the first rotating member.

[0092] The pressed surface does not have to be inclined with respect to the axis of the common shaft.

[0093] The transfer head is not limited to the one shown in this embodiment as long as it can perform the function of pressing the transfer tape against the surface to be transferred. Other transfer heads include those equipped with a transfer roller at the tip.

[0094] The transfer tool is not limited to a disposable type that cannot be used after the transfer tape runs out, but may be a refillable type that uses a refill that is a replacement part that holds the transfer material.

[0095] The reel interlocking mechanism can be modified in various ways without departing from the spirit of the present invention, as long as it can interlock the supply reel and the take-up reel. For example, the number of intermediate gears is not limited to one, but may be multiple.

[0096] Furthermore, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
