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 for linking the rotation of the supply reel and the take-up reel.

[0003] Some transfer tools of this type are provided with a reverse rotation prevention mechanism for preventing the reel from rotating backward, as shown in Patent Document 1. The reverse rotation prevention mechanism in the transfer tool shown in Patent Document 1 engages a single pawl provided on the payout gear (supply gear) that constitutes the reel interlocking mechanism with ratchet teeth provided on the inner surface of the case.

[0004] However, with this configuration, the single pawl that engages with the ratchet teeth is located away from the axis of the payout gear, which can easily cause problems such as the gear with the single pawl becoming eccentric (tilting from the intended position) when rotating. If the gear becomes eccentric when rotating, this can cause distortion or loosening of the transfer tape or malfunction of the reel interlocking mechanism.

[0005] In order to solve this problem, it has been considered to use two or more claws, but if this is done, there are dilemmas such as the problem of the noise generated during the transfer operation becoming louder, the problem of the tendency to create large resistance that can impair comfortable operation during the transfer operation, and the problem of the presence of multiple claws being likely to spoil the appearance.

[Figure 5] Cross-sectional view taken along line XX in Figure 2. [Figure 6] FIG. [Figure 7] FIG. 4 is a partially enlarged left side view showing the ratchet teeth in the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0018] In this embodiment, the present invention is applied to a transfer tool for transferring a transfer material, such as glue (not shown), to a transfer target surface such as paper. The transfer tool is configured so that transfer tape T is fed from a feed reel H, passes through a transfer head G, and is wound onto a take-up reel I.

[0019] The transfer tool comprises a transfer tool body A with a transfer head G at its tip, a slider B slidably held on the transfer tool body A, and a cap C rotatably supported on the slider B and shaped to cover the transfer head G. By sliding the slider B back and forth relative to the transfer tool body A, the cap C can take two positions: a covering position (D) where it can cover the transfer head G, and a retracted position (E) where it is retracted from the transfer head G.

[0020] The transfer tool will be described in detail below.

[0021] The transfer tool main body A includes a case F that rotatably houses a payout reel H and a take-up reel I, a transfer head G disposed at the front end of the case F, a payout reel H that is housed in the case F and on which a transfer tape T holding adhesive is wound, and a payout reel H that is housed in the case F and on which a transfer tape T holding adhesive is wound. The transfer tape T is fed from the reel H and passed through the transfer roll g1 of the transfer head G. The transfer tape T is wound up by a take-up reel I, a reel interlocking mechanism W that links the rotation of the pay-out reel H and the take-up reel I, and a ratchet mechanism K that is provided between the take-up reel I and the case F and that allows the take-up reel I to rotate forward while preventing it from rotating reversely.

[0022] The case F is made of synthetic resin that can form an internal storage space sp. The case F has left and right side walls 11, 21, a top wall 22 disposed between the upper ends of the left and right side walls 11, 21, a rear wall 23 disposed between the rear ends of the left and right side walls 11, 21, and a bottom wall 24 disposed between the lower ends of the left and right side walls 11, 21. An opening M is formed on the front side of the case F for leading the transfer tape T to the transfer head G and for introducing the transfer tape T that has passed through the transfer head G into the interior of the case F.

[0023] In this embodiment, the case F is made up of a first case member 1 having a left side wall 11 and a second case member 2 having a right side wall 21, an upper wall 22, a rear wall 23, and a lower wall 24. In other words, by combining the first case member 1 and the second case member 2, the case F is made up of a storage space sp that can store the payout reel H, the take-up reel I, and the reel interlocking mechanism W.

[0024] A first support shaft j1 protrudes from the inner surface of the left side wall 11 and rotatably supports the payout reel H and the payout gear 3 that constitutes the reel interlocking mechanism W. In addition, a second support shaft j2 protrudes from the left side wall 11 and rotatably supports the winding reel I and the winding gear 4 that constitutes the reel interlocking mechanism W.

[0025] The winding gear 4 is integrally provided on the left side of the winding reel I. The first support shaft j1 and the second support shaft j2 extend in a direction substantially perpendicular to the left side wall 11. The first support shaft j1 is provided behind the second support shaft j2.

[0026] A first locking claw t1 extending toward the second case member 2 is provided at the rear end of the left side wall 11. The first locking claw t1 is capable of engaging with a first claw receiving portion u1 provided on the rear wall 23 of the second case member 2.

[0027] A second pawl receiving portion (not shown) is provided at the lower front end portion of the left side wall 11. A second locking pawl t2 provided on the bottom wall 24 of the second case member 2 can engage with the second pawl receiving portion.

[0028] In other words, the first case member 1 and the second case member 2 rotatably support the payout gear 3, the payout reel H, and the winding reel I integrated with the winding gear 4 in the storage space sp by engaging the first and second locking claws t1 and t2 with the first and second claw receiving portions u1, respectively.

[0029] The payout gear 3 and the payout reel H are rotatably supported on a first support shaft j1. The take-up reel I integrated with the take-up gear 4 is rotatably supported on a second support shaft j2.

[0030] The left side wall 11 is provided with a guide groove (not shown) that engages with the cap C and changes the position of the cap C so that it can take the covering position (D) and the retracted position (E).

[0031] The right side wall 21 is provided on its inner surface with a first boss b1 capable of holding the tip of the first support shaft j1 and a second boss b2 capable of holding the tip of the second support shaft j2. The first boss b1 is attached to the tip of the first support shaft j1 erected from the left side wall 11. The second boss portion b2 is configured to be fitted onto the tip end of the second support shaft j2 erected from the left side wall 11.

[0032] The upper wall 22 is provided with a groove-shaped slider support portion 22a that can support the slider B so that it can slide in the front-rear direction.

[0033] The transfer head G is mainly composed of a transfer roll g1 that presses the transfer tape T against the surface to be transferred, and left and right support parts g2 that are plate-shaped and rotatably support the transfer roll g1. The left and right support parts g2 are supported by the left side wall 11.

[0034] The payout reel H comprises a cylindrical payout reel body h1 around which the transfer tape T is wound, and left and right flanges h2 provided on both left and right sides of the payout reel body h1. The payout reel body h1 is provided with a center hole ca that penetrates in the left-right direction and engages with the shaft 32 of the payout gear 3 that constitutes the reel interlocking mechanism W.

[0035] The take-up reel I takes up the transfer tape T that has been sent out from the pay-out reel H via the transfer head G. The take-up reel I is equipped with a cylindrical take-up reel body i1 that takes up the transfer tape T, left and right flanges i2 and i3 provided on both left and right ends of the take-up reel body i1, and a cylindrical boss i4 that projects outward from the right flange i3 with its axis js aligned with that of the take-up reel body i1.

[0036] A shaft hole ja is formed in the center of the take-up reel body i1, penetrating in the left-right direction and rotatably fitted onto the second support shaft j2. Note that, as will be described in detail later, a ratchet mechanism K is provided between the right side of the take-up reel I and the right side wall 21 of the second case member 2 to prevent the take-up reel I from rotating in the reverse direction.

[0037] The reel linkage mechanism W comprises a payout gear 3 rotatably supported on a first support shaft j1 and capable of rotating together with the payout reel H, and a winding gear 4 rotatably supported on a second support shaft j2 and capable of rotating integrally with the winding reel I.

[0038] The payout gear 3 comprises a disk-shaped payout gear body 31 having a plurality of teeth on its outer periphery that mesh with the winding gear 4, a shaft portion 32 that stands upright from the center of the payout gear body 31 and fits into the center hole ca in the payout reel H, and a slip-out prevention portion 33 that is provided at the tip of the shaft portion 32 and engages with the payout reel H to prevent the payout reel H from slipping out of the shaft portion 32.

[0039] In addition, a sliding mechanism S is provided between the center hole ca of the payout reel H and the shaft portion 32 of the payout gear 3, which allows relative rotation between the payout reel H and the payout gear 3 when a torque greater than a certain level is applied.

[0040] The winding gear 4 has a plurality of teeth on its outer periphery that mesh with the supply gear 3. The winding gear 4 is integrally provided on the left side of the winding reel I, with its axis js aligned with that of the winding reel I.

[0041] In this embodiment, the transfer device has a ratchet mechanism K between the winding reel I, which is a reel, and the right side wall 21 of the case F, which is a support member, to prevent the winding reel I from rotating in the reverse direction and allow it to rotate in the forward direction.

[0042] The ratchet mechanism K is made up of first and second ratchet pawls k1 and k2 provided on the right side of the winding reel I, and first and second ratchet pawls k2 and k3 provided on the inner surface of the right side wall 21 of the case F. The reel 1 has a plurality of ratchet teeth R that are circumferentially equally spaced and engageable with the first and second ratchet pawls k1 and k2. In other words, the first and second ratchet pawls k1 and k2 are provided on the reel I, and the ratchet teeth R are provided on the case F.

[0043] The ratchet mechanism K of this embodiment is arranged so that two pawls, i.e., the first and second ratchet pawls k1 and k2, do not simultaneously engage with the ratchet teeth R. In other words, the first and second ratchet pawls k1 and k2 are arranged symmetrically with respect to the axis js, which is the center of rotation of the winding reel I. An odd number (15 in this embodiment) of ratchet teeth R that can engage with the first and second ratchet pawls k1 and k2 are arranged at equal intervals in the circumferential direction.

[0044] The base ends of the first and second ratchet pawls k1, k2 are connected to the right flange i3 and annular boss i4 of the take-up reel I, respectively.

[0045] The first and second ratchet pawls k1, k2 comprise first and second base walls k11, k21 that are integrally connected to the right-side flange portion i3 and boss portion i4, first and second arm portions k12, k22 that are cantilevered by the first and second base walls k11, k21 and curved along the outer periphery of the annular boss portion i4, and first and second tip portions k13, k23 that protrude from the tips of the first and second arm portions k12, k22 and abut against the ratchet teeth R.

[0046] The first and second base walls k11 and k21 are substantially rectangular walls, and are disposed symmetrically with respect to the axis js of the winding reel I.

[0047] The first and second arm portions k12, k22 can be positioned away from the right flange portion i3 and boss portion i4 of the winding reel I. The first and second arm portions k12, k22 extend integrally from the first and second base walls k11, k21.

[0048] The first and second tip portions k13, k23 have portions that gradually narrow in width in a direction away from the axis js in a side view. The first and second tip portions k13, k23 are formed with an inclined surface n1 that is continuous with the outer peripheral surfaces of the first and second arm portions k12, k22 and that can come into sliding contact with the multiple ratchet teeth R during forward rotation, and an upright surface n2 that is located distally of the inclined surface n1, is approximately perpendicular to the rotation direction of the winding reel I, and can come into contact with the ratchet teeth R during reverse rotation.

[0049] The ratchet teeth R are provided in an odd number (15 locations) at equal intervals around the circumference. That is, the ratchet teeth R are arranged in an annular shape with the center corresponding to the axis js as the base. The ratchet teeth R form a mountain shape that convex toward the center of rotation of the winding reel I, i.e., the axis js.

[0050] The ratchet teeth R include a first inclined abutment surface r1 against which the inclined surfaces n1 of the first and second ratchet pawls k1 and k2 can abut when the winding reel I rotates forward, and a second inclined abutment surface r2 against which the upright surfaces n2 of the first and second ratchet pawls k1 and k2 can abut when the winding reel I rotates reverse. The second abutment surface r2 has a steeper slope than the first abutment surface r1. As shown in this embodiment, when an odd number of ratchet teeth R are arranged at equal intervals in the circumferential direction, the odd number of ratchet teeth R are not located symmetrically with respect to the center of rotation of the winding reel I.

[0051] When the winding reel I rotates forward, the ratchet mechanism K rotates the first and second ratchet pawls. The inclined surfaces n1 of the first and second tip portions k13, k23 of the ratchet pawls k1, k2 abut against the first abutment surfaces r1 of the ratchet teeth R. The first and second tip portions k13, k23 of the ratchet pawls k1, k2 are guided by the first abutment surfaces r1 and attempt to move toward the axis js. At this time, the first and second arm portions k12, k22 supporting the first and second tip portions k13, k23 temporarily elastically deform, allowing the first and second tip portions k13, k23 to move. In this way, when the winding reel I rotates forward, the first and second ratchet pawls k1, k2 can move over the ratchet teeth R with which they were abutting.

[0052] On the other hand, in the ratchet mechanism K, when the winding reel I attempts to rotate in the reverse direction, the upright surfaces n2 of the first and second tip portions k13, k23 of the first and second ratchet pawls k1, k2 do not come into planar contact with the second abutment surface r2, but instead come into localized (point) contact with the second abutment surface r2 of the ratchet tooth R. At this time, the first and second tip portions k13, k23 of the ratchet pawls k1, k2 cannot obtain the guiding action of the second abutment surface r2 with normal reverse torque. In this way, the winding reel I is appropriately prevented from rotating in the reverse direction.

[0053] As described in detail above, the transfer device shown in this embodiment is configured to wind the transfer tape T, which is unwound from the unwound reel H, onto the winding reel I via the transfer head G.

[0054] The ratchet mechanism K, which prevents the winding reel I from rotating in reverse, comprises first and second ratchet pawls k1 and k2 provided on the winding reel I, which is the reel, and a plurality of ratchet teeth R, which are provided on the right side wall 21 of the case F, which is the support member, and which can engage with the first and second ratchet pawls k1 and k2, and which are arranged at equal intervals in the circumferential direction.

[0055] The first and second ratchet pawls k1 and k2 constituting the ratchet mechanism K are provided so as not to engage with the ratchet teeth R at the same time.

[0056] Therefore, the transfer device shown in this embodiment can effectively suppress the problem of the winding reel I becoming easily eccentric due to the configuration for preventing the winding reel I from rotating reversely.

[0057] In other words, by arranging the two ratchet claws, the first and second ratchet claws k1 and k2, in predetermined positions, the first and second ratchet claws k1 and k2 can alternately engage with the ratchet teeth R when transferring the adhesive attached to the transfer tape T to the surface to be transferred.

[0058] Therefore, compared to a conventional ratchet mechanism that uses only one ratchet pawl that is positioned off-center relative to the axis, the winding reel I is less likely to become off-center relative to the second support shaft j2.

[0059] Therefore, the transfer tool of this embodiment can effectively suppress problems such as distortion or loosening of the transfer tape T or malfunction of the reel linkage mechanism W during transfer operations, which are caused by the configuration for preventing reverse rotation of the winding reel I.

[0060] In addition, the first and second ratchet claws k1 and k2 that constitute the ratchet mechanism K are arranged so as not to engage with the ratchet teeth R at the same time, thereby making it possible to suitably suppress the resistance force that prevents the transfer tool from rotating in the forward direction during the transfer operation.

[0061] Furthermore, the first and second ratchet pawls k1 and k2 constituting the ratchet mechanism K are arranged so as not to simultaneously engage with the ratchet teeth R. The sound generated when the first ratchet pawl k1 engages with the ratchet teeth R and the sound generated when the second ratchet pawl k2 engages with the ratchet teeth R are both generated simultaneously and become loud, and this is also appropriately suppressed.

[0062] Moreover, because the ratchet mechanism K can alternately engage the first and second ratchet pawls k1, k2 with the ratchet teeth R, the total number of ratchet teeth R arranged at equal intervals in the circumferential direction can be set to a relatively small number. In other words, compared to conventional mechanisms in which one ratchet pawl engages with multiple ratchet teeth, the ratchet mechanism K of this embodiment can set the total number of ratchet teeth R to half without impairing the reverse rotation prevention function.

[0063] This makes it less likely for users to get the impression that the ratchet teeth are too densely arranged and cluttered, and instead makes it easier to give a clean appearance that contributes to a favorable impression.

[0064] Furthermore, it is easy to form each ratchet tooth R relatively large, which reduces the need to form sharp angles, which is a significant issue with known ratchet teeth. As a result, with the ratchet mechanism K of this embodiment, it is possible to reasonably design a shape for the ratchet teeth R that allows them to easily come out of the mold during manufacturing, which not only makes it easier to process but also reduces the likelihood of manufacturing defects.

[0065] Since the first and second ratchet pawls k1, k2 are provided on the winding reel I and the ratchet teeth R are provided on the case F, which is the support member, it is easy to accurately mold the first and second ratchet pawls k1, k2 and ratchet teeth R into a predetermined shape.

[0066] The first and second ratchet pawls k1 and k2 are arranged symmetrically with respect to the center of rotation of the winding reel I, i.e., the axis js, and an odd number of ratchet teeth R are arranged in the circumferential direction.

[0067] For this reason, the first and second ratchet pawls k1, k2 are provided at positions that can suitably suppress eccentricity of the winding reel I. Moreover, such a configuration allows for flexible design so that the first and second ratchet pawls k1, k2 do not simultaneously engage with the ratchet teeth R.

[0068] In other words, if the ratchet mechanism K is configured so that the first and second ratchet pawls k1, k2 are arranged symmetrically with respect to the axis js of the winding reel I and an odd number of ratchet teeth R are arranged circumferentially, it becomes easy to set the timing at which the first ratchet pawl k1 engages with the ratchet teeth R and the timing at which the second ratchet pawl k2 engages with the ratchet teeth R to not coincide.

[0069] It is equipped with a reel interlocking mechanism W that interlocks the rotation of the supply reel H and the take-up reel I. In this embodiment, as described above, the ratchet mechanism K is configured so that the take-up reel I, which is integrally provided with the take-up gear 4, is less likely to become eccentric with respect to the axis js. Therefore, the reel interlocking mechanism W is less likely to malfunction, and the desired operation can be properly achieved.

[0070] The present invention is not limited to the above-described embodiment.

[0071] The transfer tool may be any tool that transfers the transfer material to the transfer target. In other words, the transfer material is not limited to the glue shown in this embodiment, but may be, for example, a correction agent (correction tape) for corrections or a decorative agent (decorative tape) for decorations.

[0072] Furthermore, the transfer tool is not limited to a so-called disposable type that cannot be used after the transfer tape runs out. The transfer tool may be a so-called refillable type that is configured so that a refill holding the transfer tape can be replaced with a case.

[0074] The ratchet mechanism is not limited to being provided on the take-up reel and the support member for the take-up reel, but may also be provided on the pay-out reel and the support member for the pay-out reel.

[0078] In addition to the first and second ratchet pawls, other ratchet pawls may be added. In other words, the ratchet mechanism may include three or more ratchet pawls.

[0079] 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]
