Description

[0001] This application is a divisional application of the Chinese patent application with application date of December 30, 2020, application number 202011618604.4, and invention name: "Transfer tool". Technical Field

[0002] The present invention relates to a transfer tool. Background Art

[0003] In the past, there is known a transfer tool that has a reel for releasing a transfer tape with a transfer material such as paste attached thereto, a reel for winding up the transfer tape released from the reel, and a reel linkage mechanism for linking the rotation of the reel and the reel.

[0004] Among such transfer tools, there is a transfer tool provided with a reverse rotation preventing mechanism for preventing the reel from reversing, as disclosed in Patent Document 1, for example. The reverse rotation preventing mechanism in the transfer tool disclosed in Patent Document 1 engages a claw provided on a feeding gear (feeding gear) constituting a reel interlocking mechanism with a ratchet tooth provided on the inner surface of a housing.

[0005] However, in the above structure, since the one claw engaging with the ratchet teeth is located away from the axis of the release gear, it is easy to cause the gear provided with the one claw to be eccentric (tilted from the desired posture) during rotation. If the gear is eccentric during rotation, the transfer belt may be skewed or loosened, or the reel linkage mechanism may malfunction.

[0006] In order to eliminate the above-mentioned problems, studies have been conducted in the past to make the claws more than two, but if this is done, there will be the following difficulties: the sound generated during the transfer operation will become louder, a large resistance will be easily generated that can damage the comfortable movement during the transfer operation, and the appearance will be easily damaged due to the presence of multiple claws.

[0038] Below, refer to Figures 1 to 7 An embodiment of the present invention will be described.

[0039] This embodiment applies the present invention to a transfer tool for transferring a transfer material (not shown) to a transfer target surface of a paper sheet, etc. The transfer tool winds up a transfer tape T unwound from a reel H for unwinding onto a reel I for winding via a transfer head G.

[0040] The transfer tool includes a transfer tool body A having a transfer head G provided at a tip portion, a slider B slidably held on the transfer tool body A, and a cap C rotatably supported relative to the slider B and having a shape covering the transfer head G. The cap C can assume a covering position (D) capable of covering the transfer head G and a retreat position (E) retreating from the transfer head G by sliding the slider B in the front-rear direction relative to the transfer tool body A.

[0041] The transfer tool will be described in detail below.

[0042] The transfer tool body A comprises: a shell F, which rotatably accommodates a pay-out reel H and a take-up reel I; a transfer head G, which is arranged at the front end of the shell F; a pay-out reel H, which is accommodated in the shell F and is wound with a transfer tape T with paste; a take-up reel I, which is accommodated in the shell F and is used to take up the transfer tape T that is paid out from the pay-out reel H and passes through the transfer roller g1 of the transfer head G; a reel linkage mechanism W, which links the rotation of the pay-out reel H and the take-up reel I; and a ratchet mechanism K, which is arranged between the take-up reel I and the shell F, and allows the take-up reel I to rotate forward and prevent reverse rotation.

[0043] The housing F is a member made of synthetic resin that can form a storage space sp inside. The housing F includes 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 housing F for leading the transfer tape T toward the transfer head G and for leading the transfer tape T that has passed through the transfer head G into the interior of the housing F.

[0044] In this embodiment, the housing F is composed of a first housing member 1 having a left side wall 11 and a second housing member 2 having a right side wall 21, an upper wall 22, a rear wall 23, and a lower wall 24. That is, by combining the first housing member 1 and the second housing member 2, a housing F is formed in which a storage space sp capable of storing a reel H for unwinding, a reel I for winding, and a reel linkage mechanism W is formed.

[0045] A first support shaft j1 is protrudingly provided on the inner surface of the left side wall 11, rotatably supporting the reel H for unwinding and the unwinding gear 3 constituting the reel linkage mechanism W. In addition, a second support shaft j2 is protrudingly provided on the left side wall 11, rotatably supporting the reel I for unwinding and the reel linkage mechanism W.

[0046] The winding gear 4 is integrally provided on the left side of the winding reel 1. The first support shaft j1 and the second support shaft j2 extend in a direction substantially orthogonal to the left side wall 11. The first support shaft j1 is provided at the rear side of the second support shaft j2.

[0047] A first locking claw t1 extending in the direction of the second housing member 2 is provided at a rear end portion of the left side wall 11. The first locking claw t1 can engage with a first claw receiving portion u1 provided on the rear wall 23 of the second housing member 2.

[0048] A second claw receiving portion (not shown) is provided at the lower portion of the front end portion of the left side wall 11. The second locking claw t2 provided on the lower wall 24 of the second housing member 2 can engage with the second claw receiving portion.

[0049] That is, the first shell member 1 and the second shell member 2 support the pay-out gear 3, the pay-out reel H and the winding reel I integrated with the winding gear 4 in a rotatable manner in the accommodation space sp by engaging the first and second locking claws t1 and t2 with the first and second claw receiving parts u1 respectively.

[0050] The pay-out gear 3 and the pay-out reel H are supported so as to be rotatable with respect to the first support shaft j1. The take-up reel I integrated with the take-up gear 4 is supported so as to be rotatable with respect to the second support shaft j2.

[0051] Furthermore, a guide groove (not shown) is provided on the left side wall 11 , which engages with the cap C and changes the posture of the cap C so that the cap C can take the covering position (D) and the retracted position (E).

[0052] A first hub b1 capable of holding the top end of the first support shaft j1 and a second hub b2 capable of holding the top end of the second support shaft j2 are provided on the inner surface side of the right side wall 21. The first hub b1 is in a form that can be externally fitted to the top end of the first support shaft j1 erected from the left side wall 11, and the second hub b2 is in a form that can be externally fitted to the top end of the second support shaft j2 erected from the left side wall 11.

[0053] The upper wall 22 is provided with a groove-shaped slider support portion 22 a that can support the slider B so as to be slidable in the front-rear direction.

[0054] The transfer head G mainly includes a transfer roller g1 for pressing the transfer belt T against the transfer target surface and left and right plate-shaped support parts g2 for rotatably supporting the transfer roller g1. The left and right support parts g2 are supported by the left side wall 11.

[0055] The unwinding reel H includes a unwinding reel body h1 having a cylindrical shape and winding the transfer tape T thereon, and left and right flanges h2 provided on both left and right sides of the unwinding reel body h1. The unwinding reel body h1 is provided with a center hole ca penetrating in the left-right direction and engaging with the shaft 32 of the unwinding gear 3 constituting the reel linkage mechanism W.

[0056] The take-up reel I takes up the transfer tape T fed from the unwinding reel H via the transfer head G. The take-up reel I includes a cylindrical take-up reel body i1 for taking up the transfer tape T, left and right flanges i2 and i3 provided at left and right ends of the take-up reel body i1, and a cylindrical hub i4 protruding outward from the right flange i3 so that the axis js is aligned with the take-up reel body i1.

[0057] An axial hole ja is formed in the center of the winding reel body i1 and penetrates in the left-right direction so as to be engaged with the second support shaft j2 in a manner that allows rotation relative to the second support shaft j2. In addition, as described in detail later, a ratchet mechanism K is provided between the right side of the winding reel I and the right side wall 21 in the second housing member 2 to prevent the winding reel I from reversing.

[0058] The reel interlocking mechanism W includes a feeding gear 3 rotatably supported on the first support shaft j1 and rotatable together with the feeding reel H, and a winding gear 4 rotatably supported on the second support shaft j2 and rotatable integrally with the winding reel I.

[0059] The pay-out gear 3 includes a disc-shaped pay-out gear body 31 having a plurality of teeth meshing with the winding gear 4 provided on the outer periphery, a shaft portion 32 erected from the central portion of the pay-out gear body 31 and engaged with the central hole ca in the pay-out reel H, and an anti-detachment portion 33 provided at the top end of the shaft portion 32 and engaged with the pay-out reel H to restrict the pay-out reel H from detaching from the shaft portion 32.

[0060] Furthermore, a slide mechanism S is provided between the center hole ca of the reel H for feeding and the shaft portion 32 of the feeding gear 3 for allowing relative rotation of the reel H for feeding and the feeding gear 3 when a torque greater than a certain value acts.

[0061] The winding gear 4 is provided with a plurality of teeth meshing with the unwinding gear 3 at the outer peripheral edge. The winding gear 4 is integrally provided on the left side portion of the winding reel 1 so that the axis js is aligned with the winding reel 1.

[0062] Therefore, the transfer tool of this embodiment is provided with a ratchet mechanism K for preventing the reel 1 from rotating reversely and allowing forward rotation between the reel 1 for winding as a reel and the right side wall 21 in the housing F as a supporting member.

[0063] The ratchet mechanism K includes a first and a second ratchet pawl k1 and k2 provided on the right side of the winding reel I and a plurality of ratchet teeth R provided on the inner surface of the right side wall 21 in the housing F and with which the first and the second ratchet pawls k1 and k2 can be engaged and are arranged at equal intervals in the circumferential direction. In other words, the first and the second ratchet pawls k1 and k2 are provided on the winding reel I, and the ratchet teeth R are provided on the housing F.

[0064] The ratchet mechanism K of this embodiment is arranged in such a way that the two pawls, i.e., the first and second pawls k1 and k2, do not engage with the ratchet teeth R at the same time. That is, the first and second pawls k1 and k2 are arranged symmetrically with respect to the rotation center, i.e., the axis js, of the winding reel I. Furthermore, an odd number (15 in this embodiment) of ratchet teeth R that can engage with the first and second pawls k1 and k2 are arranged at equal intervals in the circumferential direction.

[0065] The base ends of the first and second pawls k1 and k2 are connected to the flange portion i3 on the right side of the winding reel 1 and the annular hub portion i4, respectively.

[0066] The first and second pawls k1 and k2 include first and second base walls k11 and k21 integrally connected to the flange portion i3 and the hub portion i4 on the right side, first and second arm portions k12 and k22 supported in a cantilevered manner on the first and second base walls k11 and k21 and arranged in a curved shape along the outer circumference of the annular hub portion i4, and first and second top end portions k13 and k23 protruding from the top ends of the first and second arm portions k12 and k22 and abutting against the ratchet teeth R.

[0067] The first and second base walls k11 and k21 are substantially rectangular in shape. The first and second base walls k11 and k21 are symmetrically arranged with respect to the axis js in the winding reel I.

[0068] The first and second arm portions k12 and k22 can be located away from the flange portion i3 and the hub portion i4 on the right side of the winding reel I. The first and second arm portions k12 and k22 are integrally extended from the first and second base walls k11 and k21.

[0069] The first and second top ends k13 and k23 have a shape portion whose width gradually narrows in the direction away from the axis js in a side view. The first and second top ends k13 and k23 are formed with an inclined surface n1 that is continuous with the outer peripheral surface of the first and second arm parts k12 and k22 and can slide against the plurality of ratchet teeth R during forward rotation, and a rising surface n2 that is located closer to the top end side than the inclined surface n1 and is substantially orthogonal to the rotation direction of the winding reel I and can abut against the ratchet teeth R during reverse rotation.

[0070] An odd number (15) of ratchet teeth R are arranged at equal intervals in the circumferential direction. That is, the ratchet teeth R are arranged in an annular shape with the center corresponding to the axis js as the reference. The ratchet teeth R are convex toward the rotation center of the winding reel I, that is, the axis js.

[0071] The ratchet teeth R have an inclined first contact surface r1 with which the inclined surface n1 of the first and second ratchet pawls k1 and k2 can contact when the winding reel I rotates forward, and an inclined second contact surface r2 with which the rising surface n2 of the first and second ratchet pawls k1 and k2 can contact when the winding reel I is to be reversed. The second contact surface r2 forms a steeper slope than the first contact surface r1. When the odd-numbered ratchet teeth R are arranged at equal intervals in the circumferential direction as shown in the present embodiment, the odd-numbered ratchet teeth R are not located at symmetrical positions with respect to the rotation center of the winding reel I.

[0072] When the winding reel I rotates forward, the inclined surface n1 of the first and second top ends k13 and k23 of the first and second ratchet pawls k1 and k2 abuts against the first contact surface r1 of the ratchet teeth R. In addition, the first and second top ends k13 and k23 of the ratchet pawls k1 and k2 are guided by the first contact surface r1 and are intended to move in the direction of the axis js. At this time, the first and second arm portions k12 and k22 supporting the first and second top ends k13 and k23 are temporarily elastically deformed to allow the movement of the first and second top ends k13 and k23. In this way, when the winding reel I rotates forward, the first and second ratchet pawls k1 and k2 can pass over the abutting ratchet teeth R.

[0073] On the other hand, when the winding reel 1 is to be reversed, the rising surfaces n2 of the first and second top ends k13 and k23 of the first and second ratchet pawls k1 and k2 do not contact the second contact surface r2 but partially contact (point contact) the second contact surface r2 of the ratchet teeth R. At this time, the first and second top ends k13 and k23 of the ratchet pawls k1 and k2 cannot obtain the guiding effect of the second contact surface r2 under the normal reversal torque. In this way, the reversal of the winding reel 1 is appropriately prevented.

[0074] As described above in detail, the transfer tool shown in this embodiment winds up the transfer tape T unwound from the unwound reel H via the transfer head G onto the wind-up reel I.

[0075] Furthermore, a ratchet mechanism K for preventing the reel I for winding up has a first and a second ratchet pawl k1, k2 provided on the reel I for winding up as a reel and a plurality of ratchet teeth R provided on the right side wall 21 in a shell F as a supporting member, and the first and the second ratchet pawls k1, k2 can be engaged with each other and are arranged at equal intervals in the circumferential direction.

[0076] The first and second 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.

[0077] Therefore, according to the transfer tool shown in this embodiment, it is possible to appropriately suppress the inconvenience that the winding reel 1 is easily eccentric due to the structure for preventing the reel 1 from being reversed.

[0078] That is, by arranging the two pawls, ie, the first and second pawls k1 and k2 at predetermined positions, the first and second pawls k1 and k2 can alternately engage with the ratchet teeth R when transferring the paste attached to the transfer tape T to the transfer target surface.

[0079] Therefore, compared with a conventional ratchet mechanism using only one pawl disposed at a position offset from the axis center, the winding reel 1 is less likely to be eccentric with respect to the second support shaft j2.

[0080] Therefore, the transfer tool of this embodiment can appropriately suppress undesirable situations such as skewing and loosening of the transfer tape T or malfunction of the reel linkage mechanism W during the transfer operation due to the structure for preventing the reel 1 for winding from reversing.

[0081] Furthermore, since the first and second ratchet claws k1 and k2 constituting the ratchet mechanism K are arranged so as not to engage with the ratchet teeth R at the same time, the resistance that prevents the normal rotation of the transfer tool during the transfer operation can be appropriately suppressed.

[0082] Moreover, since the first and second pawls k1 and k2 constituting the ratchet mechanism K are arranged in a manner that does not engage with the ratchet teeth R at the same time, the sound generated when the first pawl k1 engages with the ratchet teeth R and the sound generated when the second pawl k2 engages with the ratchet teeth R are appropriately suppressed from being generated simultaneously to form loud sounds.

[0083] Furthermore, since the ratchet mechanism K can make the first and second pawls k1 and k2 alternately engage with the ratchet teeth R, the total number of ratchet teeth R arranged at equal intervals in the circumferential direction can be set to be relatively small. That is, compared with the conventional structure in which one pawl is engaged with a plurality of ratchet teeth, in the ratchet mechanism K of the present embodiment, the total number of ratchet teeth R can be set to one-half without impairing the function of preventing reverse rotation.

[0084] This makes it difficult for the user or the like to have a complicated impression that the ratchet teeth are arranged too densely, or rather, it is easy to give a neat appearance that contributes to a proper impression.

[0085] In addition, it is easy to form each ratchet tooth R relatively large, which can reduce the necessity of forming a significant acute angle portion in the known ratchet teeth. As a result, if the ratchet mechanism K in this embodiment, the shape of the ratchet teeth R that can be easily separated from the mold during manufacturing can be reasonably designed, so that not only is processing easy to carry out, but manufacturing defects are also unlikely to occur.

[0086] Since the first and second ratchet pawls k1 and k2 are provided on the winding reel I and the ratchet teeth R are provided on the housing F as a supporting member, it is easy to form the first and second ratchet pawls k1 and k2 and the ratchet teeth R in predetermined forms with high accuracy.

[0087] The first and second ratchet pawls k1 and k2 are symmetrically arranged with respect to the axis js which is the rotation center of the winding reel I, and an odd number of ratchet teeth R are arranged in the circumferential direction.

[0088] Therefore, the first and second ratchet pawls k1 and k2 are provided at positions that can appropriately suppress the eccentricity of the winding reel I. Moreover, with this structure, the design for preventing the first and second ratchet pawls k1 and k2 from being engaged with the ratchet teeth R at the same time can be flexibly performed.

[0089] In other words, if the ratchet mechanism K is constructed so that the first and second pawls k1 and k2 are symmetrically arranged with respect to the axis js of the winding reel I and an odd number of ratchet teeth R are arranged in the circumferential direction, it is easy to set them in such a way that the timing of the engagement of the first pawl k1 with the ratchet teeth R and the timing of the engagement of the second pawl k2 with the ratchet teeth R are inconsistent.

[0090] The reel linkage mechanism W is provided to link the rotation of the unwinding reel H and the winding reel I. In the present embodiment, as described above, the ratchet mechanism K is configured so that the winding reel I integrally provided with the winding gear 4 is not easily eccentric relative to the axis js. Therefore, the reel linkage mechanism W is unlikely to cause malfunction and can properly achieve the desired action.

[0091] In addition, the present invention is not limited to the embodiments described in detail above.

[0092] The transfer tool may be any transfer tool as long as it transfers the transfer material to the transfer object. In other words, the transfer material is not limited to the paste shown in this embodiment, and may be, for example, a correction agent (correction tape) for correction or a decorating agent (decoration tape) for decoration.

[0093] The transfer tool is not limited to a disposable type transfer tool that cannot be used after the transfer tape is exhausted, but may be a so-called replacement type transfer tool in which a replacement part holding the transfer tape can be replaced with a housing.

[0094] The ratchet mechanism is not limited to being provided on the winding reel and the supporting member of the winding reel, but may be provided on the unwinding reel and the supporting member of the unwinding reel.

[0095] The ratchet mechanism is not limited to the one in which the first and second pawls are provided on the reel and the plurality of ratchet teeth are provided on the support member. That is, the ratchet mechanism may also be the one in which the first and second pawls are provided on the support member and the plurality of ratchet teeth are provided on the reel.

[0096] The ratchet mechanism is not limited to the above-mentioned embodiment as long as the first and second pawls do not engage with the ratchet teeth at the same time. For example, the first and second pawls may be asymmetrically arranged with respect to the rotation center of the reel, and the ratchet teeth engaged with the first and second pawls may be arranged in an even number or an odd number in the circumferential direction. In other words, regardless of whether the ratchet teeth are an even number or an odd number, the desired purpose can be achieved as long as the positions of the first and second pawls are set to predetermined asymmetrical positions that do not engage with the ratchet teeth at the same time.

[0097] As long as the protruding directions of the first and second pawls and the ratchet teeth are in a relationship where they can mesh with each other, they may be protruded in any direction.

[0098] In addition to the first and second pawls, other pawls may be added. In other words, the pawls constituting the ratchet mechanism may be three or more.

[0099] In addition, the specific structure of each part is not limited to the above-mentioned embodiment, and various modifications are possible within the scope not departing from the gist of the present invention.
