Description

[Technical field]

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

[0002] Conventionally, there has been known a transfer device that includes a payout reel that pays out a transfer tape having a transfer material such as glue attached thereto, a take-up reel for taking up the transfer tape paid out from the payout reel, and a reel linkage mechanism that links the rotation of the payout reel and the take-up reel.

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

[0004] However, with such a configuration, the pawl that engages with the ratchet teeth is located away from the axis of the payout gear, which can easily cause a problem in that the gear with the pawl becomes eccentric (tilted from the intended position) when rotating. If the gear becomes eccentric when rotating, the transfer tape may become distorted or loose, or the reel interlocking mechanism may malfunction.

[0005] In order to solve such problems, it has been considered to have two or more claws. However, if this is done, there are dilemmas in that the noise generated during the transfer operation becomes louder, there is a tendency for large resistance to be generated that can make the transfer operation less comfortable, and the presence of multiple claws can easily spoil the appearance.

[Figure 7] FIG. 4 is a partially enlarged left side view showing the ratchet teeth in the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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, namely, glue (not shown), to a transfer target surface such as paper. The transfer tool winds a transfer tape T, which is paid out from a pay-out reel H, around a transfer head G and is taken up by a take-up reel I.

[0019] The transfer tool comprises a transfer tool body A having 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. The cap C can take a covering position (D) in which it can cover the transfer head G and a retracted position (E) in which it is retracted from the transfer head G by sliding the slider B back and forth relative to the transfer tool body A.

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

[0021] The transfer device main body A is equipped with a case F that rotatably houses a pay-out reel H and a take-up reel I therein, a transfer head G arranged at the front end of the case F, the pay-out reel H housed in the case F and wound with transfer tape T holding adhesive, a take-up reel I housed in the case F for winding up the transfer tape T that is paid out from the pay-out reel H and passes through the transfer roll g1 of the transfer head G, a reel linkage 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 allows the take-up reel I to rotate forward while preventing it from rotating reversely.

[0022] The case F is made of synthetic resin capable of forming an internal storage space sp. The case F has left and right side walls 11, 21, an upper 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 lower 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 inside of the case F.

[0023] In this embodiment, the case F is composed 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 composed, which has a storage space sp that can store the payout reel H, the winding reel I, and the reel interlocking mechanism W.

[0024] A first spindle 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 spindle 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 adapted to be engaged with a first claw receiving portion u1 provided on the rear wall 23 of the second case member 2.

[0027] A second claw receiving portion (not shown) is provided at the lower part of the front end portion of the left side wall 11. A second locking claw t2 provided on the bottom wall 24 of the second case member 2 can be engaged with the second claw 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, 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 winding 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] A first boss b1 capable of holding the tip end of the first support shaft j1 and a second boss b2 capable of holding the tip end of the second support shaft j2 are provided on the inner surface of the right side wall 21. The first boss b1 is configured to fit onto the tip end of the first support shaft j1 erected from the left side wall 11, and the second boss b2 is configured to fit 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 capable of supporting the slider B so as to be slidable 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 transfer target surface, 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 includes a cylindrical payout reel body h1 on 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 penetrating in the left-right direction and engaging 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 sent out from the unwinding reel H via the transfer head G. The take-up reel I includes a cylindrical take-up reel body i1 that takes up the transfer tape T, left and right flanges i2, i3 provided on both left and right ends of the take-up reel body i1, and a cylindrical boss i4 that protrudes 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 that penetrates in the left-right direction is formed in the center of the winding reel body i1 and rotatably fits onto the second support shaft j2. Note that, as will be described in detail later, a ratchet mechanism K that prevents the winding reel I from rotating in the reverse direction is provided between the right side of the winding reel I and the right side wall 21 of the second case member 2.

[0037] The reel linkage mechanism W includes a payout gear 3 that is rotatably supported on a first support shaft j1 and can rotate together with the payout reel H, and a winding gear 4 that is rotatably supported on a second support shaft j2 and can rotate 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 peripheral edge 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 a central 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 above a certain level is applied.

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

[0041] In this embodiment, the transfer tool 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 while allowing it to rotate in the forward direction.

[0042] The ratchet mechanism K includes first and second ratchet pawls k1, k2 provided on the right side of the winding reel I, and a plurality of ratchet teeth R that are provided on the inner surface of the right side wall 21 of the case F and are arranged at equal intervals in the circumferential direction and with which the first and second ratchet pawls k1, k2 can engage. In other words, 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.

[0043] The ratchet mechanism K in this embodiment is arranged so that two pawls, i.e., the first and second ratchet pawls k1, k2, do not simultaneously engage with the ratchet teeth R. In other words, the first and second ratchet pawls k1, k2 are arranged symmetrically with respect to the axis js, which is the center of rotation of the winding reel I. An odd number of ratchet teeth R (15 in this embodiment) that can engage with the first and second ratchet pawls k1, 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 a right flange portion i3 and an annular boss portion i4 of the winding reel I, respectively.

[0045] The first and second ratchet pawls k1, k2 include 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 in shape. The first and second base walls k11 and k21 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 are integrally extended 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 circumferential surfaces of the first and second arm portions k12, k22 and can slide against the ratchet teeth R during forward rotation, and an upright surface n2 that is located on the tip side of the inclined surface n1, is substantially 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 in the circumferential direction. In other words, the ratchet teeth R are arranged in an annular shape based on a center corresponding to the axis js. The ratchet teeth R form a mountain shape that protrudes 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 reversely. 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] In the ratchet mechanism K, when the winding reel I rotates forward, the inclined surfaces n1 of the first and second tip portions k13, k23 of the first and second ratchet pawls k1, k2 abut against the first abutment surface 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 surface 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 overcome the ratchet teeth R that they have been abutting.

[0052] On the other hand, in the ratchet mechanism K, when the winding reel I is about 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 local (point) contact with the second abutment surface r2 of the ratchet teeth 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 tool shown in this embodiment is configured to wind the transfer tape T, which is unwound from a supply reel H, onto a take-up reel I via a transfer head G.

[0054] The ratchet mechanism K, which prevents the winding reel I from rotating in reverse, is provided with first and second ratchet pawls k1, 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, k2, and which are arranged at equal intervals in the circumferential direction.

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

[0056] For this reason, the transfer tool 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 in reverse.

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

[0058] Therefore, compared to a conventional ratchet mechanism that uses only one ratchet pawl that is positioned offset from the axis, the winding reel I is less likely to become offset from 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, 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 normal direction during the transfer operation.

[0061] Furthermore, the first and second ratchet pawls k1, k2 that constitute the ratchet mechanism K are arranged so as not to engage with the ratchet teeth R at the same time, so that the sound generated when the first ratchet pawl k1 engages with the ratchet teeth R and the other sound generated when the second ratchet pawl k2 engages with the ratchet teeth R are appropriately suppressed from occurring simultaneously and becoming loud.

[0062] Moreover, since 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. That is, compared to a conventional ratchet mechanism in which one ratchet pawl is engaged with a plurality of ratchet teeth, the ratchet mechanism K of this embodiment can set the total number of ratchet teeth R to half without impairing the function of preventing reverse rotation.

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

[0064] Also, each ratchet tooth R can be easily formed to be relatively large, reducing the need to form acute angles, which was prominent in known ratchet teeth. As a result, with the ratchet mechanism K of this embodiment, the shape of the ratchet teeth R can be reasonably designed to be easily removed from the mold during manufacturing, making it not only easy to process but also less likely to cause 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 precisely mold the first and second ratchet pawls k1, k2 and the ratchet teeth R into a predetermined shape.

[0066] The first and second ratchet pawls k1, k2 are provided symmetrically with respect to the center of rotation, i.e., the axis js, of the winding reel I, and an odd number of ratchet teeth R are provided 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 engage with the ratchet teeth R at the same time.

[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 provided in the circumferential direction, 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 so that they do not coincide.

[0069] The reel interlocking mechanism W interlocks the rotation of the payout reel H and the winding reel I. In this embodiment, as described above, the ratchet mechanism K is configured so that the winding reel I, which is integral with the winding gear 4, is unlikely to become eccentric with respect to the axis js. Therefore, the reel interlocking mechanism W is unlikely to malfunction, and can properly achieve the desired operation.

[0070] It should be noted that the present invention is not limited to the embodiment described above in detail.

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

[0072] In addition, 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 refill exchange type that is configured so that a refill holding the transfer tape can be replaced with a case.

[0073] The support member of the reel is not limited to the case, and may be, for example, a support plate of the refill. That is, one example of the refill is one that includes a support plate as a support member, and a pay-out reel and a wind-up reel that are rotatably supported on the support plate. The ratchet mechanism of the refill may be provided between the pay-out reel and the support plate as a support member, or may be provided between the wind-up reel and the support plate as a support member.

[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.

[0076] The ratchet mechanism may be any mechanism in which the first and second ratchet pawls do not simultaneously engage with the ratchet teeth, and the form is not limited to that shown in the above embodiment. For example, the first and second ratchet pawls may be provided asymmetrically with respect to the center of rotation of the reel, and the ratchet teeth with which the first and second ratchet pawls engage may be provided in an even or odd number in the circumferential direction. In other words, whether the number of ratchet teeth is an even or odd number, the desired purpose can be achieved as long as the positions of the first and second ratchet pawls are set to predetermined asymmetric positions that do not simultaneously engage with the ratchet teeth.

[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 without departing from the spirit of the present invention. [Explanation of symbols]
