Description

Transfer tool

Technical Field

The present invention relates to a transfer tool.

Background

Conventionally, various transfer tools have been known, in which a transfer belt to which a transfer material such as a correction tape or a paste (japanese character: paste) is attached is pressed against a transfer target surface by a transfer head, and the transfer material is transferred to the transfer target surface.

In the coating film transfer tool (1) disclosed in patent document 1, a base member (16) is supported rotatably with respect to a base member support shaft (15). The coating film transfer tool (1) is configured such that the rotation lock of the supply spool (4) is released when in use (i.e., when the transfer belt (3) is pressed against the transfer target surface (S) by the transfer head (5)), and the rotation of the supply spool (4) is locked when not in use (i.e., when the transfer belt (3) is not pressed against the transfer target surface (S) by the transfer head (5)). According to the structure of the coating film transfer tool (1), the resistance to the rotation of the supply reel (4) is reduced during use, so that a light transfer operation which is helpful for a user can be expected.

However, the coating film transfer tool (1) disclosed in patent document 1 is a transfer tool in which the base member (16) and the transfer head (5) operate integrally, and therefore the transfer head (5) moves relative to the case (2) when in use. As a result, when the coating film transfer tool (1) disclosed in patent document 1 is used, there is a possibility that the user will feel uncomfortable when using the tool.

< housing A >

The case a is a synthetic resin case capable of forming a housing space sp therein. The case a includes left and right side walls j1, k1, an upper wall k2 disposed between upper ends of the left and right side walls j1, k1, a rear wall k3 disposed between rear ends of the left and right side walls j1, k1, and a lower wall k4 disposed between lower ends of the left and right side walls j1, k 1. An opening H for guiding out the transfer belt T to the transfer head B and guiding the transfer belt T passing through the transfer head B into the inside of the casing a is formed in the front side of the casing a.

The housing a is constituted by a first housing member J having a left side wall J1, and a second housing member K having a right side wall K1, an upper wall K2, a rear wall K3, and a lower wall K4. By combining the first casing member J and the second casing member K, a casing a is formed in which a housing space sp capable of housing the reel D for unwinding, the reel E for winding, the reel interlocking mechanism F, and the clutch mechanism G is formed.

A first support shaft j2 that rotatably supports the winding spool E and the winding gear E4 is provided to protrude from the left side wall j 1. The winding gear E4 is provided integrally with the left side of the winding spool E. A second support shaft j3 that rotatably supports the reel supporting member C for payout and rotatably supports the intermediate gear f2 is provided to protrude from the left side wall j 1. The first and second support shafts j2, j3 extend in a direction substantially perpendicular to the left side wall j 1. The first support shaft j2 is disposed forward of the second support shaft j 3.

A first locking portion j4, which can be locked by the leaf spring C6 provided in the reel support member C for unwinding, protrudes toward the housing space sp side between the opening H and the first support shaft j2 in the left side wall j 1.

The posture maintaining projection C4 of the reel supporting member C for payout is provided to project outward, i.e., in the direction of the left side wall j1 so that the axial center coincides with the support shaft C2. The receiving hole j6 is formed in a shape that allows the posture-retaining projection c4 to move up and down. That is, the receiving hole j6 is formed in an elongated hole shape in which the posture maintaining projection C4 is movable within a range in which the reel supporting member C for payout is rotatable with respect to the second support shaft j3 disposed in the case a.

A prismatic head mounting portion j7 is provided to protrude from the front end portion of the left side wall j1, and the head mounting portion j7 can be fitted into a mounting hole B1 formed in the base end portion of the transfer head B and penetrating in the left-right direction.

The proximal end portion of the pawl member L is pivotally supported by a pin pn provided to protrude from the right flange portion E3 of the winding spool E, and the distal end portion of the pawl member L is engaged with the third ratchet teeth k7, whereby the normal rotation of the winding spool E is permitted and the reverse rotation is prohibited.

The right side wall k1 is provided with first ratchet teeth k6 engageable with a first ratchet pawl D3 provided on the reel D for unwinding. The first ratchet teeth k6 are arranged in a partial circular arc shape in the rear upper portion of the right side wall k 1. When the first ratchet tooth k6 is engaged with the first ratchet pawl D3 integrally provided on the reel-out spool D, the normal rotation of the reel-out spool D can be restricted or prohibited by the cooperation between the first ratchet tooth k6 and the first ratchet pawl D3.

As shown in fig. 1, the casing a of this embodiment is provided with a protective cover q1 for protecting the upper side and a protective cover q2 for protecting the lower side of the transfer head B. The upper protective cover q1 is a sliding type cover that is slidable in the front-rear direction with respect to the upper wall k2 of the case a, and the lower protective cover q2 is a rotating type cover that is supported so as to be rotatable with respect to the case a. The upper protective cover q1 and the lower protective cover q2 can be interlocked by a cover interlocking mechanism I using a link member q 3. That is, the cover link mechanism I is configured to be capable of opening and closing the upper protective cover q1 and the lower protective cover q2 between a state in which the transfer head B can be covered and a state in which the transfer head B can be used.

< transfer head B >

The support shaft c2 is inserted into a shaft holding hole s12 of the clutch member s1 and pivotally supports the clutch member s 1. The clutch member s1 is inserted into the center hole D11 of the reel D for payout, and the clutch member s1 is attached so as to be rotatable integrally with the reel D for payout. In other words, the reel D for unwinding is supported rotatably with respect to the support shaft c2 via the clutch member s 1.

The tape guide c3 is cylindrical and protrudes in a direction perpendicular to the base c 1. The belt guide portion c3 can be in sliding contact with the inner surface (upper surface) of the transfer belt T paid out from the reel D for payout.

The reel support member C for payout having the above-described configuration is configured to be rotatable between a first posture (M) and a second posture (N) with respect to the casing a. More specifically, the reel supporting member C is configured to be rotatable relative to the case a between a first posture (M) in which engagement between the first ratchet pawl D3 provided on the reel D for payout and the first ratchet teeth k6 provided on the case a is permitted, and a second posture (N) in which engagement between the first ratchet pawl D3 provided on the reel D for payout and the first ratchet teeth k6 provided on the case a is not permitted.

The reel supporting member C for payout is constantly biased in the first posture (M) direction by a leaf spring C6 as an elastic member. The reel supporting member C for payout is supported so as to be rotatable with its axial center aligned with the intermediate gear f 2.

< reel for payout D >

The reel D for unwinding includes: a cylindrical discharging spool body d1 extending in the left-right direction around which the transfer belt T is wound, a side plate d2 provided on the right side of one of the discharging spool body d1, and a plurality of four first ratchet pawls d3 located at the peripheral edge of the side plate d2 and cantilevered with respect to the side plate d 2.

The reel body d1 for payout has a center hole d11 penetrating in the left-right direction. A plurality of groove portions d12 extending in the left-right direction are provided on the inner peripheral surface of the center hole d 11. The plurality of protrusions s11 provided on the outer peripheral portion of the clutch member s1 can be fitted into the specific groove portion d 12.

The side plate portion d2 has a plate shape extending in a direction orthogonal to the reel main body portion d1 for unwinding. A portion of the outer edge portion of the side plate portion d2, which is connected to the base end portion of the first ratchet pawl d3, is formed so as to protrude outward, i.e., in a sheet-like manner in the anti-axial direction.

The first ratchet pawl d3 includes a ratchet arm d31 having a base end integrally connected to the side plate portion d2, and a pawl portion d32 provided at a distal end portion of the ratchet arm d31 so as to protrude outward, i.e., in the opposite axial direction. The pawl portion d32 is engageable with first ratchet teeth k6, and the first ratchet teeth k6 are arranged in a partial arc shape on the inner surface of the right side wall k1 of the case a.

< spool for winding E >

The take-up spool E includes: a winding spool main body portion e1 configured to wind the transfer belt T around the winding spool main body portion e 1; left and right flange portions e2, e3, the left and right flange portions e2, e3 being provided at left and right end portions of the take-up spool body portion e 1; a winding gear e4 provided integrally with an outer side portion of the left flange portion e2 such that an axial center of the winding gear e4 coincides with the winding spool main body portion e 1; and a second ratchet tooth e5 provided on the outer side of the winding gear e4 such that the axial center of the second ratchet tooth e5 coincides with the winding gear e 4.

The take-up spool body e1 is entirely cylindrical and extends in the lateral direction, and has a shaft hole e11 formed in the center thereof and penetrating in the lateral direction, and fitted rotatably to the first support shaft j 2.

The right flange e3 has pins pn projecting from a plurality of, three locations, which are connected to the base end of the pawl member L. The pawl member L can inhibit the reverse rotation of the take-up spool E by engaging the tip end portion with the third ratchet teeth k 7. In other words, a second winding spool reverse rotation prevention ratchet mechanism W2 that prevents the winding spool E from reversing is provided between the winding spool E and the case a.

< reel linkage mechanism F >

The reel linkage mechanism F includes: a payout gear f1, the payout gear f1 being rotatably supported by the support shaft C2 of the payout reel support member C and being integrally rotatable with the payout reel D; a take-up gear E4 provided integrally with the take-up spool E and rotatably supported by the first support shaft j2 and by the take-up gear E4; and an intermediate gear f2, the intermediate gear f2 being supported by the second support shaft j3, interposed between the release gear f1 and the take-up gear e4, and meshing with the release gear f1 and the take-up gear e 4.

The discharge gear f1 has a disk shape with a plurality of teeth provided on the outer periphery thereof to mesh with the intermediate gear f 2. A shaft hole f11 is provided in the center of the discharge gear f 1. One end of the clutch member s1 is inserted into the shaft hole f11 of the release gear f 1. The release pawl s13 provided at one end of the clutch member s1 prevents the release gear f1 from coming off the clutch member s 1. The payout gear f1 is supported via a clutch member s1 inserted into the shaft hole f11 so as to be rotatable together with the payout spool D with respect to a support shaft C2 of the payout spool support member C.

Further, a sliding mechanism S that allows relative rotation between the reel D for payout and the payout gear f1 when a torque equal to or greater than a certain value is applied is provided between the reel D for payout and the payout gear f 1. The sliding mechanism S is configured mainly of a clutch member S1 and a coil spring S2, the clutch member S1 is inserted into the center hole D11 of the reel D for feeding and the projection S11 is engaged with the groove D12 provided in the center hole D11, thereby being rotatable integrally with the reel D for feeding around the support shaft c2, and the coil spring S2 brings the clutch member S1 into pressure contact with the feeding gear f1 by a predetermined pressing force. The coil spring s2 is interposed between the flange portion s14 provided to the clutch member s1 and the peripheral edge portion of the shaft hole f11 in the discharge gear f 1.

The winding gear E4 is disposed on the outer surface side of the left flange E2 of the winding spool E, and is provided with a plurality of teeth that mesh with the intermediate gear f 2. The winding gear E4 is provided integrally with the left side of the winding spool E so that the axial center thereof coincides with the winding spool E.

The intermediate gear f2 is supported to be rotatable in a state of being prevented from coming off the second pivot shaft j3 provided on the left side wall j 1.

< Clutch mechanism G >

The clutch mechanism G can take a normal rotation permitting state (P) in which the normal rotation of the pay-out spool D can be permitted at the time of the transfer operation shown in fig. 4 and 5, and can take a normal rotation restricting state (R) in which the normal rotation of the pay-out spool D can be restricted at the time of the transfer cancellation shown in fig. 1 to 3.

The term "at the time of transfer operation" refers to a time when the transfer head B presses the transfer belt T to which the transfer material is attached against the transfer target surface while the transfer belt T is operated (while traveling on the transfer target surface). The term "at the time of release of transfer" refers to a time other than the time of transfer operation.

Then, the clutch mechanism G in this embodiment can take the normal rotation allowable state (P) by the tension pw applied to the transfer belt T at the time of the transfer operation.

The clutch mechanism G includes: a case a capable of accommodating the pay-out spool D and the take-up spool E and rotatably supporting the take-up spool E; a reel support member C for payout supported rotatably with respect to the case a; and a reel-for-pay D supported rotatably with respect to the reel-for-pay support member C.

The clutch mechanism G releases the engagement between the reel D for discharge and the casing a in the normal rotation permission state (P) shown in fig. 4 and 5, and restricts the normal rotation of the reel D for discharge by engaging the reel D for discharge with the casing a in the normal rotation restriction state (R) shown in fig. 1 to 3.

That is, the first ratchet pawl d3 is not engaged with the first ratchet tooth k6 in the normal rotation permitted state (P), and the first ratchet pawl d3 is engageable with the first ratchet tooth k6 in the normal rotation restricted state (R).

Further, a first reel reverse rotation prevention ratchet mechanism W1 as a ratchet mechanism is provided between the reel support member C for payout and the reel E for winding that constitute the clutch mechanism G, the first reel reverse rotation prevention ratchet mechanism being capable of preventing reverse rotation of the reel E for winding in the first posture (M) in the normal rotation restricted state (R). The first winding spool reverse rotation prevention ratchet mechanism W1 includes a second ratchet tooth C7 provided on the unwinding spool support member C, and a second ratchet tooth E5 provided on the winding spool E and engageable with the second ratchet tooth C7.

Next, the operation of the clutch mechanism G in this embodiment will be described.

When the transfer is released, the reel-out supporting member C pivotally supported by the case a is urged by the plate spring C6 to take the first posture (M). At this time, the first ratchet pawl D3 in the reel-out D supported by the reel-out supporting member C engages with the first ratchet teeth k6 provided in the case a, and the normal rotation of the reel-out D is restricted.

Next, an outline will be given of an operation performed when a user starts a transfer operation for applying a correction tape onto a transfer target surface using the transfer tool of the present embodiment.

In the transfer operation, that is, when the transfer head B operates the transfer belt T with the correction tape attached thereto while pressing the transfer belt T against the transfer target surface, the transfer belt T located between the leading end pressing portion B2 of the transfer head B and the transfer target surface pulls the transfer belt T on the upstream side (the reel D side for unwinding) to the downstream side. At this time, the tape guide C3 of the reel support member C for feeding and the support shaft C2 that pivotally supports the reel D for feeding are biased downward (clockwise in fig. 4 and 5 about the second support shaft j 3) by the tension pw of the transfer belt T during the transfer operation, and the reel support member C for feeding is rotated in the direction of the second posture (N) against the biasing force of the plate spring C6.

That is, the clutch mechanism G can take the normal rotation allowable state (P) by rotating the reel supporting member C for payout from the first posture (M) to the second posture (N) by the tension pw applied to the transfer belt T at the time of the transfer operation.

When the user stops the transfer operation, the reel support member C for payout returns from the second posture (N) to the first posture (M) by the urging force of the leaf spring C6, and the normal rotation of the reel D for payout returns to the restricted state.

As described above in detail, the transfer tool according to the present embodiment winds the transfer belt T paid out from the reel D for pay-out on the reel E for take-up via the transfer head B. The transfer tool is provided with a clutch mechanism G which can take a normal rotation permission state (P) capable of permitting normal rotation of the reel D for discharge at the time of transfer operation and can take a normal rotation restriction state (R) capable of restricting normal rotation of the reel D for discharge at the time of transfer cancellation. The clutch mechanism G can take the normal rotation allowable state (P) by the tension pw applied to the transfer belt T at the time of the transfer operation.

Therefore, if the transfer tool according to the present embodiment is used, it is possible to provide a transfer tool that can reduce the resistance to the transfer belt T during the transfer operation and contribute to the comfortable transfer operation of the user. In other words, if the transfer tool of the present embodiment is used, the resistance to the rotation of the reel D for unwinding during the transfer operation can be reduced, and therefore, it contributes to providing a user with a suitable feeling of use.

That is, the clutch mechanism G can adopt the normal rotation allowable state (P) by the tension pw applied to the transfer belt T at the time of transfer operation, and therefore, a configuration capable of suitably reducing the resistance to rotation of the reel-out D at the time of use can be realized without adopting an unstable configuration such that the transfer head moves relative to the casing as in the related art.

Therefore, if the transfer tool of the present embodiment is used, it is possible to give the user a suitable feeling of use based on a structure in which the transfer head B is difficult to move relative to the casing a without giving the user a feeling of incongruity due to the relative movement of the transfer head with respect to the casing as in the conventional art.

The clutch mechanism G includes: a case a capable of accommodating the pay-out spool D and the take-up spool E and rotatably supporting the take-up spool E; a reel support member C for payout supported rotatably with respect to the case a; and a reel-for-pay D supported rotatably with respect to the reel-for-pay support member C. The clutch mechanism G releases the engagement between the reel D for payout and the case a in the normal rotation permitted state (P), and restricts the normal rotation of the reel D for payout by engaging the reel D for payout with the case a in the normal rotation restricted state (R).

Therefore, by providing the reel support member C for payout supported so as to be rotatable with respect to the housing a and supporting the reel D for payout ON the reel support member C, it is possible to appropriately set the presence or absence of engagement (ON/OFF of engagement) between the reel D for payout and the housing a.

The reel support member C is configured to be rotatable relative to the casing a between a first posture (M) in which engagement between the reel D and the casing a is permitted and a second posture (N) in which the reel D and the casing a are not engaged. The reel support member C for payout is constantly biased in the first posture (M) direction by a leaf spring C6 as an elastic member.

Therefore, the clutch mechanism G can stably position the reel supporting member C for payout in the first posture (M) at the time of transfer cancellation. Therefore, the transfer tool is easily designed to be able to shift the reel supporting member C for payout from the first posture (M) to the second posture (N) by the tension pw applied to the transfer belt T at the time of the transfer operation.

That is, if the transfer tool is used, the reel supporting member C for feeding can be appropriately designed so as to be able to shift from the first posture (M) to the second posture (N) against the urging force of the plate spring C6 as the elastic member based on the tension pw applied to the transfer belt T at the time of the transfer operation.

The leaf spring C6 as an elastic member is provided integrally with the reel support member C for payout, and has a distal end portion capable of elastically contacting the case a.

Therefore, the reel supporting member C for payout can stably take the predetermined posture, i.e., the first posture (M) at the time of the transfer release, without increasing the number of components.

The reel interlocking mechanism F is provided for interlocking the rotation of the pay-out reel D and the take-up reel E. The reel interlocking mechanism F includes a payout gear F1 rotatable together with the payout reel D, a take-up gear E4 rotatable together with the take-up reel E, and an intermediate gear F2 interposed between the payout gear F1 and the take-up gear E4. The reel supporting member C for payout is supported so as to be rotatable with its axial center aligned with the intermediate gear f 2.

Therefore, even if the reel-out gear f1 supported by the reel-out supporting member C moves relative to the housing a together with the reel-out supporting member C, it can smoothly mesh with the intermediate gear f 2.

The reel D for unwinding is provided with a first ratchet pawl D3, and the housing a is provided with first ratchet teeth k6 engageable with the first ratchet pawl D3. The clutch mechanism G is configured such that the first ratchet pawl d3 is not engaged with the first ratchet teeth k6 in the forward rotation permitted state (P), and the first ratchet pawl d3 is engageable with the first ratchet teeth k6 in the forward rotation restricted state (R).

Therefore, by applying the first ratchet pawl d3 and the first ratchet teeth k6 engageable with the first ratchet pawl d3, a desired operation can be appropriately performed.

The transfer tool includes a first take-up spool reverse rotation prevention ratchet mechanism W1 as a reverse rotation prevention ratchet mechanism capable of preventing reverse rotation of the take-up spool E in the normal rotation restricted state (R). The first winding spool reverse rotation prevention ratchet mechanism W1 includes a second ratchet tooth C7 provided on the unwinding spool support member C, and a second ratchet tooth E5 provided on the winding spool E and engageable with the second ratchet tooth C7.

Therefore, the reel support member C for unwinding can prevent the reverse rotation of the reel E in the normal rotation restricted state (R) by using a structure capable of performing a rotational operation with respect to the casing a.

The reel supporting member C for payout has a support shaft C2 capable of supporting the reel D for payout.

Therefore, the reel D for payout can rotate about the support shaft C2 of the reel support member C for payout, and can also move relative to the case a together with the reel support member C for payout.

The reel supporting member C for feeding includes a tape guide portion C3, and the tape guide portion C3 is disposed below the rotation center of the casing a and can guide the entry angle of the transfer belt T to the transfer head B.

Therefore, the transfer belt T paid out from the reel D for pay-out can be appropriately guided to the transfer head B.

Furthermore, the present invention is not limited to the embodiments described in detail above.

The transfer tool may be any transfer tool as long as it is a transfer tool for transferring a transfer material to a transfer target. In other words, the transferred product is not limited to the correction tape agent (film-like correction agent) described in the present embodiment, and may be, for example, paste or a decorative agent (decorative tape) for decoration.

The transfer tool may be a disposable type transfer tool that cannot be used after the transfer belt is used up, or a replacement type transfer tool configured to be able to replace a replacement holding the transfer belt with respect to the housing.

The reel-out supporting member may not be provided with a ratchet pawl engageable with ratchet teeth of the reel-up.

The ratchet pawl of the reel-out support member provided so as to be engageable with the ratchet teeth of the reel-up spool does not necessarily have to be completely separated from the ratchet teeth in the normal rotation permitting state (second posture). In other words, the ratchet pawl of the reel-out support member may be engageable with the ratchet teeth of the reel-up in the normal rotation permitted state (second posture).

The elastic member that biases the reel support member for payout in the direction of the first posture is not limited to the plate spring, and may be, for example, a torsion coil spring, rubber, or the like.

The tip end portion of the leaf spring provided integrally with the reel supporting member for feeding may be capable of elastically contacting the transfer head.

The intermediate gear constituting the spool linkage is not limited to a single gear, and may be a plurality of gears.

The number of ratchet pawls provided on the reel for unwinding can be set to an appropriate number.

The specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
