Description

Technical Field

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

[0002] Conventionally, there has been known a transfer tool including a pay-off reel for discharging a transfer belt to which a transfer material such as glue is attached, a take-up reel for taking up the transfer belt discharged from the pay-off reel, and a reel interlocking mechanism for interlocking the rotation of the pay-off reel and the take-up reel.

[0003] In such a transfer tool, for example, as shown in Patent Document 1, there is a transfer tool provided with an anti-reverse mechanism for preventing the reverse rotation of the reel. The anti-reverse mechanism in the transfer tool shown in Patent Document 1 causes one claw provided on a pay-off gear (supply gear) constituting the reel interlocking mechanism to engage with ratchet teeth provided on the inner surface of the housing.

[0004] However, in the above structure, since one claw that engages with the ratchet teeth is located at a position away from the axis of the pay-off gear, there is a problem that the gear provided with one claw is likely to be eccentric (tilt from the desired posture) during rotation. If the gear is eccentric during rotation, it may cause the transfer belt to be skewed or slack, or cause malfunction of the reel interlocking mechanism.

[0005] In order to solve the above problems, it has been studied to make the claws into two or more. However, in such a case, there are the following dilemmas: the problem that the sound generated during the transfer operation becomes louder, the problem that a large resistance that can damage the comfortable operation during the transfer operation is likely to occur, and the problem that the appearance is likely to be damaged due to the presence of multiple claws.

[0037] The following is for reference Figures 1 to 7 To illustrate one embodiment of the present invention.

[0038] This embodiment applies the invention to a transfer apparatus for transferring a paste (not shown) as a transfer material to a transfer target surface such as paper. The transfer apparatus takes the transfer tape T released from the release reel H and wound it onto the take-up reel I via the transfer head G.

[0039] The transfer apparatus includes a transfer apparatus body A with a transfer head G at its top end, a slider B that is slidably held on the transfer apparatus body A, and a cap C supported so as to be rotatable relative to the slider B and having a shape that covers the transfer head G. Furthermore, the cap C can be positioned in a covering position (D) and a retracted position (E) that avoids the transfer head G by sliding the slider B relative to the transfer apparatus body A in the front-back direction.

[0040] The following is a detailed description of the transfer tools.

[0041] The main body A of the transfer apparatus comprises: a housing F, which rotatably houses an output reel H and a take-up reel I; a transfer head G disposed at the front end of the housing F; the output reel H, housed within the housing F, which is wound with a transfer tape T holding paste; the take-up reel I, housed within the housing F, which is used to take up the transfer tape T that has been output from the output reel H and passed through the transfer roller g1 of the transfer head G; a reel linkage mechanism W that links the rotation of the output reel H and the take-up reel I; and a ratchet mechanism K disposed between the take-up reel I and the housing F, which allows the take-up reel I to rotate forward and prevents it from rotating backward.

[0042] The housing F is a synthetic resin component capable of forming an internal receiving space sp. The housing F includes left and right side walls 11 and 21, an upper wall 22 disposed between the upper ends of the left and right side walls 11 and 21, a rear wall 23 disposed between the rear ends of the left and right side walls 11 and 21, and a lower wall 24 disposed between the lower ends of the left and right side walls 11 and 21. An opening M is formed on the front side of the housing F for guiding the transfer belt T toward the transfer head G and guiding the transfer belt T, after passing through the transfer head G, into the interior of the housing F.

[0043] 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 having a receiving space sp capable of accommodating a reel H for releasing, a reel I for winding, and a reel linkage mechanism W.

[0044] A first support shaft j1 is provided on the inner surface of the left side wall 11, supporting the unloading reel H and the unloading gear 3 constituting the reel linkage mechanism W in a rotatable manner. In addition, a second support shaft j2 is provided on the left side wall 11, supporting the winding reel I and the winding gear 4 constituting the reel linkage mechanism W in a rotatable manner.

[0045] Furthermore, the winding gear 4 is integrally disposed 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 orthogonal to the left side wall 11. The first support shaft j1 is disposed further rearward than the second support shaft j2.

[0046] A first locking claw t1 extending in the direction of the second housing member 2 is provided at the rear end of the left side wall 11. The first locking claw t1 can engage with the first claw receiving part u1 provided on the rear wall 23 of the second housing member 2.

[0047] A second claw receiving part (not shown) is provided at the lower part of the front end of the left side wall 11. A second locking claw t2 provided on the lower wall 24 of the second housing member 2 can engage with the second claw receiving part.

[0048] In other words, the first housing component 1 and the second housing component 2 support the release gear 3, the release reel H and the take-up reel I integrated with the take-up gear 4 in a rotatable manner in the receiving space sp by engaging the first and second locking claws t1 and t2 with the first and second claw receiving parts u1 respectively.

[0049] The release gear 3 and the release reel H are supported so that they can rotate relative to the first support shaft j1. The take-up reel I, which is integrated with the take-up gear 4, is supported so that it can rotate relative to the second support shaft j2.

[0050] In addition, 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 in a manner that allows the cap C to take on a covered position (D) and a retracted position (E).

[0051] 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 of the right side wall 21. The first hub b1 is configured to be fitted outward to the top end of the first support shaft j1, which is erected from the left side wall 11, and the second hub b2 is configured to be fitted outward to the top end of the second support shaft j2, which is erected from the left side wall 11.

[0052] The upper wall 22 is provided with a groove-shaped slider support 22a that supports the slider B in a manner that allows it to slide in the front-back direction.

[0053] The transfer head G is mainly composed of a transfer roller g1 that presses the transfer belt T against the object to be transferred, and plate-shaped left and right support parts g2 that support the transfer roller g1 in a rotatable manner. The left and right support parts g2 are supported on the left side wall 11.

[0054] The unloading reel H has a cylindrical unloading reel body h1 for rolling the transfer tape T and left and right flanges h2 provided on the left and right sides of the unloading reel body h1. The unloading reel body h1 is provided with a central hole ca that passes through in the left and right direction and engages with the shaft 32 of the unloading gear 3 that constitutes the reel linkage mechanism W.

[0055] The take-up reel I takes the transfer tape T fed from the unload reel H via the transfer head G. The take-up reel I has a cylindrical take-up reel body i1 for taking the transfer tape T, left and right flanges i2 and i3 provided at the left and right ends of the take-up reel body i1, and a cylindrical hub i4 that protrudes outward from the right flange i3 so that the axis js is aligned with the take-up reel body i1.

[0056] A through-hole ja in the left-right direction is formed at the center of the main body i1 of the winding reel, which is rotatable relative to the second support shaft j2. In addition, as detailed later, a ratchet mechanism K is provided between the right side of the winding reel I and the right side wall 21 of the second housing member 2 to prevent the winding reel I from reversing.

[0057] The reel linkage mechanism W includes a release gear 3 that is rotatably supported on a first support shaft j1 and can rotate together with the release reel H, and a take-up gear 4 that is rotatably supported on a second support shaft j2 and can rotate integrally with the take-up reel I.

[0058] The release gear 3 includes a disc-shaped release gear body 31 with multiple teeth on its outer periphery that mesh with the take-up gear 4, a shaft portion 32 that is erected from the center of the release gear body 31 and engages with the center hole ca in the release reel H, and an anti-detachment portion 33 that is provided at the top of the shaft portion 32 and engages with the release reel H to prevent the release reel H from disengaging from the shaft portion 32.

[0059] Furthermore, a sliding mechanism S is provided between the center hole ca in the release reel H and the shaft 32 of the release gear 3, which allows relative rotation between the release reel H and the release gear 3 when a certain torque is applied.

[0060] The take-up gear 4 has multiple teeth on its outer periphery that mesh with the release gear 3. The take-up gear 4 is integrally mounted on the left side of the take-up reel I in such a way that the shaft center js is aligned with the take-up reel I.

[0061] Therefore, in this embodiment, the transfer device has a ratchet mechanism K provided between the take-up reel I (which serves as a reel) and the right side wall 21 of the housing F (which serves as a support member) to prevent the take-up reel I from rotating in reverse and to allow forward rotation.

[0062] The ratchet mechanism K has first and second pawls k1 and k2 disposed on the right side of the winding reel I, and a plurality of ratchet teeth R disposed on the inner surface of the right side wall 21 of the housing F, wherein the first and second pawls k1 and k2 can engage and are arranged at equal intervals in the circumferential direction. In other words, the first and second pawls k1 and k2 are disposed on the winding reel I, and the ratchet teeth R are disposed on the housing F.

[0063] In this embodiment, the ratchet mechanism K is configured such that the two pawls, namely the first and second pawls k1 and k2, do not simultaneously engage with the ratchet teeth R. That is, the first and second pawls k1 and k2 are symmetrically arranged with reference to the rotation center, i.e., the axis js, of the winding reel I. Furthermore, an odd number of ratchet teeth R, which can engage with the first and second pawls k1 and k2, are arranged at equal intervals in the circumferential direction (15 in this embodiment).

[0064] The base ends of the first and second pawls k1 and k2 are respectively connected to the right flange i3 and the annular hub i4 of the winding reel I.

[0065] The first and second pawls k1 and k2 have first and second base walls k11 and k21 integrally connected to the flange portion i3 and hub portion i4 on the right side, first and second arm portions k12 and k22 that are supported in a cantilever shape on the first and second base walls k11 and k21 and are curved along the outer periphery of the annular hub portion i4, and first and second top portions k13 and k23 that protrude from the top of the first and second arm portions k12 and k22 and abut against the ratchet teeth R.

[0066] The first and second base walls k11 and k21 are roughly rectangular in shape. The first base wall k11 and the second base wall k21 are symmetrically arranged with reference to the axis js in the winding reel I.

[0067] The first and second arms k12 and k22 can be located away from the right flange i3 and hub i4 in the winding reel I. The first and second arms k12 and k22 extend integrally from the first and second base walls k11 and k21.

[0068] The first and second top portions k13 and k23 have a shape that gradually narrows in width when viewed from the side in the direction away from the axis js. The first and second top portions k13 and k23 have an inclined surface n1 that is continuous with the outer peripheral surface of the first and second arm portions k12 and k22 and can slide in contact with multiple ratchet teeth R when rotating forward, and a vertical surface n2 that is located on the top side of the inclined surface n1, is approximately orthogonal to the rotation direction of the winding reel I, and can abut against the ratchet teeth R when rotating in reverse.

[0069] An odd number (15) of ratchet teeth R are evenly spaced in the circumferential direction. That is, the ratchet teeth R are arranged in a ring shape with the center corresponding to the axis js as the reference. The ratchet teeth R are mountain-shaped and protrude towards the rotation center of the winding reel I, i.e., the axis js.

[0070] The ratchet teeth R have an inclined first contact surface r1 that abuts against the inclined surfaces n1 of the first and second pawls k1 and k2 when the winding reel I rotates forward, and an inclined second contact surface r2 that abuts against the upright surfaces n2 of the first and second pawls k1 and k2 when the winding reel I rotates backward. The second contact surface r2 forms a steeper slope compared to the first contact surface r1. When an odd number of ratchet teeth R are arranged at equal intervals in the circumferential direction as shown in this embodiment, the odd number of ratchet teeth R are not symmetrically positioned with respect to the rotation center of the winding reel I.

[0071] When the winding reel I rotates forward, the inclined surfaces n1 of the first and second tip portions k13 and k23 of the first and second pawls k1 and k2 abut against the first contact surface r1 of the ratchet tooth R. Furthermore, the first and second tip portions k13 and k23 of the pawls k1 and k2 are guided by the first contact surface r1 to move in the axial direction js. At this time, the first and second arm portions k12 and k22 supporting the first and second tip portions k13 and k23 undergo temporary elastic deformation, allowing the first and second tip portions k13 and k23 to move. Thus, when the winding reel I rotates forward, the first and second pawls k1 and k2 can pass over the contacting ratchet tooth R.

[0072] On the other hand, when the winding reel I needs to reverse, the raised surfaces n2 of the first and second tip portions k13 and k23 of the first and second pawls k1 and k2 do not abut against the second contact surface r2, but only partially abut against the second contact surface r2 of the ratchet tooth R (point contact). At this time, the first and second tip portions k13 and k23 of the pawls k1 and k2 cannot receive the guiding effect of the second contact surface r2 under normal reversing torque. In this way, the reversal of the winding reel I is properly prevented.

[0073] As detailed above, the transfer apparatus shown in this embodiment winds the transfer tape T released from the release reel H onto the take-up reel I via the transfer head G.

[0074] Furthermore, the ratchet mechanism K for preventing the winding reel I from reversing has a first and a second pawl k1 and k2 provided in the winding reel I, which is a reel, and a plurality of ratchet teeth R provided in the right side wall 21 of the housing F, which is a support member, and the first and second pawl k1 and k2 can engage and are arranged at equal intervals in the circumferential direction.

[0075] The first and second pawls k1 and k2 constituting the ratchet mechanism K are configured not to engage with the ratchet teeth R simultaneously.

[0076] Therefore, if it is the transfer device shown in this embodiment, it is possible to appropriately suppress the undesirable situation that the winding reel I is prone to eccentricity due to the configuration used to prevent the winding reel I from reversing.

[0077] In other words, by positioning the two pawls, namely the first and second pawls k1 and k2, in predetermined positions, the first and second pawls k1 and k2 can alternately engage with the ratchet teeth R during the operation of transferring the paste applied to the transfer belt T to the transfer target surface.

[0078] Therefore, compared with the conventional ratchet mechanism that uses only one pawl positioned off-center relative to the axis, the winding reel I is less likely to be off-center relative to the second support shaft j2.

[0079] Therefore, if it is the transfer tool of this embodiment, it is possible to appropriately suppress adverse situations such as skewing or loosening of the transfer belt T or malfunction of the reel linkage mechanism W during the transfer operation due to the configuration used to prevent the reel I for taking off from reversing.

[0080] Furthermore, since the first and second pawls k1 and k2 constituting the ratchet mechanism K are configured not to engage with the ratchet teeth R simultaneously, the resistance that hinders the forward rotation during the transfer operation of the transfer tool can be appropriately suppressed.

[0081] Furthermore, since the first and second pawls k1 and k2 constituting the ratchet mechanism K are configured not to engage with the ratchet teeth R simultaneously, the simultaneous generation of one type of sound when the first pawl k1 engages with the ratchet teeth R and the other type of sound when the second pawl k2 engages with the ratchet teeth R, thus preventing the sound from becoming loud, is also appropriately suppressed.

[0082] Furthermore, since the ratchet mechanism K allows the first and second pawls k1 and k2 to 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 engages with multiple ratchet teeth, in the ratchet mechanism K of this embodiment, the total number of ratchet teeth R can be set to half the number without compromising the reverse rotation prevention function.

[0083] Therefore, it is difficult to give users the impression of a complicated ratchet configuration with too many teeth, or rather, it is easier to give a neat appearance that helps to create a suitable impression.

[0084] Furthermore, it is easy to form each ratchet tooth R to be relatively large, which reduces the necessity of forming a portion with a significant acute angle in the known ratchet teeth. As a result, in the ratchet mechanism K of this embodiment, the shape of the ratchet teeth R that is easy to detach from the mold during manufacturing can be reasonably designed. Therefore, not only is machining easy, but manufacturing defects are also less likely to occur.

[0085] Since the first and second pawls k1 and k2 are located on the winding reel I and the ratchet tooth R is located on the housing F which serves as a support member, the first and second pawls k1 and k2 and the ratchet tooth R, which are in a predetermined shape, can be easily formed with high precision.

[0086] The first and second pawls k1 and k2 are symmetrically set with reference to the rotation center, i.e., the axis js, of the winding reel I. The ratchet teeth R have an odd number in the circumferential direction.

[0087] Therefore, the first and second pawls k1 and k2 are positioned to appropriately suppress the eccentricity of the winding reel I. Moreover, with this structure, the design to prevent the first and second pawls k1 and k2 from engaging simultaneously with the ratchet teeth R can be flexibly implemented.

[0088] In other words, if the ratchet mechanism K is configured such that the first and second pawls k1 and k2 are symmetrically arranged with reference 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 the timing of the engagement of the first pawl k1 with the ratchet tooth R and the timing of the engagement of the second pawl k2 with the ratchet tooth R to be inconsistent.

[0089] The system includes a reel linkage mechanism W that links the rotation of the unloading reel H and the winding reel I. In this embodiment, as described above, the ratchet mechanism K is configured in such a way that the winding reel I, on which the winding gear 4 is integrally mounted, is unlikely to become eccentric relative to the axis js. Therefore, the reel linkage mechanism W is less likely to cause malfunctions and can properly achieve the desired action.

[0090] Furthermore, the present invention is not limited to the embodiments detailed above.

[0091] The transfer tool is simply used to transfer the material to the object to be transferred, and can be any transfer tool. In other words, the transfer material is not limited to the paste shown in this embodiment; for example, it can also be a correction agent (correction tape) or a decorative agent (decorative tape).

[0092] Furthermore, the transfer device is not limited to the so-called disposable type transfer device that cannot be used after the transfer belt is exhausted. The transfer device can also be a so-called replacement type transfer device, which is configured to replace the replacement part holding the transfer belt relative to the housing.

[0093] The support member of the reel is not limited to the housing; for example, it can also be a support plate of a replacement component. That is, as an example of a replacement component, a replacement component can be provided that has a support plate as a support member and a reel for unloading and a reel for winding supported and rotatable relative to the support plate. The ratchet mechanism of the replacement component can be provided between the reel for unloading and the support plate as a support member, or it can be provided between the reel for winding and the support plate as a support member.

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

[0095] The ratchet mechanism is not limited to a ratchet mechanism in which the first and second pawls are located on the reel and multiple ratchet teeth are located on the support member. That is, the ratchet mechanism can also be a ratchet mechanism in which the first and second pawls are located on the support member and multiple ratchet teeth are located on the reel.

[0096] The ratchet mechanism only requires that the first and second pawls do not engage with the ratchet teeth simultaneously, and its form is not limited to the form shown in the above embodiments. For example, it can also be configured such that the first and second pawls are arranged asymmetrically with respect to the rotation center of the reel, and the number of ratchet teeth engaged by the first and second pawls is either even or odd in the circumferential direction. That is to say, regardless of whether the number of ratchet teeth is even or odd, as long as the positions of the first and second pawls are set to a predetermined asymmetrical position where they do not engage with the ratchet teeth simultaneously, the desired purpose can be achieved.

[0097] As long as the protruding directions of the first and second pawls and ratchet teeth are in a meshing relationship, they can be set to protrude in any direction.

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

[0099] In addition, the specific structure of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
