Abstract

PROBLEM TO BE SOLVED: To attach or detach a supply reel on which a transfer tape is wound at replacing or assembling by forming a structure such that an intermediate member and a protrusion are slid to one another when a predetermined or more tension is generated at the tape due to an increase in the member or a winding amount. SOLUTION: Since a bulged surface 28 is a surface bulged to an inside, a sufficient elastic force can be obtained. Since both sides of the bulged surface are connected to each other so that its elastic portion is supported at both ends, a stable elastic force can be maintained for a long-term use of the transfer implement. A connecting portion 29 is engaged with a recess 30 provided on a supply reel 4, and an intermediate member 27 is interlocked to a rotation of the reel 4. A gap is provided between the recess 30 and the portion 28 to loosely engage the reel 4 with the member 27. Thus, when used, the reel 4 and a first gear 12 can be effectively interlocked and rotated. Therefore, when the reel is replaced or assembled, the reel 4 can be easily attached or detached while the member 28 remains retained at the protrusion 15.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer tool for transferring a coating film of a transfer tape onto paper or the like.

[0002]

2. Description of the Related Art Conventionally, a coating material such as a modifying agent, an adhesive or a coloring agent is provided on a base material such as paper or film having a releasing property, processed into a tape shape, and applied to a transfer object such as a paper surface. 2. Description of the Related Art A transfer tape having a structure in which a film is pressed and transferred is known.

In addition, a supply reel having a transfer tape wound thereon and a take-up reel for winding the transfer tape are provided inside the case, and the transfer tape which is fed with the rotation of the supply reel is provided outside the case. The supply reel and the take-up reel are interlocked with each other by passing the leading end of the transfer head to the paper surface or the like by pressing the end portion of the transfer head against the paper surface and moving it laterally. By moving
A transfer tool having a configuration in which a transfer tape after transferring a coating film at the tip of a transfer head is wound on a take-up reel inside a case is also well known.

[0004] Usually, the supply reel and the take-up reel are interlocked by gears provided on the respective reels.
At the same time as the transfer tape is unwound from the supply reel, the take-up reel winds up the transferred transfer tape more than the unwound amount, and the tape is always loosened with tension applied to the transfer tape. There is no configuration.

[0005] By the way, the transfer tool having the above-mentioned structure continuously reduces the outer diameter of the transfer tape wound on the supply reel side when not in use by continuously transferring, and conversely winds up the transferred tape. The outer diameter of the take-up reel is increased, and the take-up amount increases, and the take-up amount gradually exceeds the pay-out amount, causing excessive tension on the transfer tape. At the same time, a situation occurs.

Therefore, conventionally, the transfer tool has been provided on the supply reel with a sliding mechanism for suppressing an excessive tension applied to the transfer tape. FIG. 9 is a cross-sectional view showing an example of a conventional transfer tool sliding mechanism. Referring to FIG. 9, a conventional transfer tool sliding mechanism 101 has a supply reel 103, a take-up reel 104, and a transfer tape 105 wound around a reel disposed inside a case.

[0007] A gear 106 formed separately is provided below the supply reel 103.
A gear 107 is formed below 4. Further, a protrusion 108 having a smaller diameter than a center hole (not shown) provided in the supply reel 103 is formed above the gear 106, and a through hole (not shown) is formed at the center of the protrusion 108. ing.

Further, a through hole (not shown) of the gear 106 is loosely fitted to a support shaft 109 provided on the inner surface of the case 102 and is rotatably held.
Between them, a cylindrical elastic friction member 110 is press-fitted and fixed. The take-up reel 104 and the gear 107
The through-hole (not shown) formed in this case is loosely fitted to a support shaft 111 provided on the inner surface of the case 102 and is held rotatably. The elastic friction member 110 is formed from an elastic material such as rubber or elastomer.

The gear 106 has an arc-shaped elastic tongue 112 having a free end on the opposite side of the rotation direction at a position substantially intermediate between the outer edge and the center of the gear 106. A claw 113 protruding downward is formed at the tip of. A plurality of grooves 114 are radially formed on the inner surface of the case 102 facing the claws 113 along the trajectory of the rotation of the claws 113, and the supply reel 103 is moved by the engagement of the claws 113 and the grooves 114. A well-known ratchet mechanism configured to rotate only in the feeding direction is provided.

The elastic friction member 110 is disposed in a slightly compressed state between the outer surface of the projection 109 and the inner surface of the supply reel 103, and the frictional force and the compression force of the contact surface of the elastic friction member 110 are reduced. Supply reel 10 by the elasticity by
3 and the projection 109 are fixed, and the supply reel 103 and the gear 106 rotate in conjunction with the feeding of the transfer tape 105.

The gear portion 115 provided on the gear 106 and the gear portion 116 provided on the gear 107 mesh with each other, and the take-up reel 104 also rotates in conjunction with the rotation of the supply reel 103. The take-up reel 104 takes up the supply reel 10
3, the tension of the transfer tape 105 suppresses the elastic force and the frictional force of the elastic friction member 110 and the protrusion 1
09 and the supply reel 103 slide, and the transfer tape 105
The structure is such that no more than a certain limit of tension is applied to it.

FIG. 10 is a sectional view showing an example of another sliding mechanism of the conventional transfer tool. In FIG. 10, the sliding mechanism 201 has a protrusion 204 having a smaller diameter than a center hole (not shown) provided in the supply reel 203 above the gear 202, and a protrusion 204 on the upper circumference of the protrusion 204. A plurality of resilient pieces 205 having an upper end as a free end are formed, and a claw 206 projecting outward is formed at the upper end of the resilient piece 205. Others are the same as the above-mentioned sliding mechanism 101.

The claw 206 is provided on the supply reel 203 in a state where the resilient piece 205 is slightly compressed.
The supply reel 203 and the protrusion 205 are fixed by the resilience of the transfer tape 207, and the supply reel 203 and the gear 202 rotate in conjunction with the transfer of the transfer tape 207.

When a certain amount of tension is applied to the transfer tape 207, the tension of the transfer tape 207 is reduced.
5, the projecting portion 204 and the supply reel 203 are in sliding contact with each other, and the transfer tape 207 is prevented from being subjected to a tension exceeding a certain limit.

[0015]

However, in the structure shown in FIG. 9, the elastic friction member 110 has a cylindrical shape or an annular shape made of rubber or elastomer. And the outer surface of the protrusion 109 is in contact with the entire circumference, so that the frictional force at the time of rest is large, and the initial stage of slipping out when a certain amount of tension is generated on the transfer tape is most difficult to be slippery, and smooth transfer is performed. I couldn't do that.

Further, since the take-up reel 104 is loosely fitted on the support shaft 111, it can be easily attached and detached.
The supply reel 103 is pressed from above against the resilience and frictional force of the elastic friction member 110 at the time of replacement or assembly, and requires force and skill at that time. Sometimes, a finger is also applied to a certain transfer tape 105, and the wound transfer tape 105 may be displaced in a spiral shape in the axial direction or the transfer tape 105 may be unraveled.

Alternatively, in the structure shown in FIG. 10, when the supply reel 203 is replaced or assembled, the supply reel 203 is pressed from above against the resilience of the resilient piece 205. Since power and skill are required, a finger may sometimes be caught on the transfer tape 207 that has been erroneously wound, and the wound transfer tape 207 may be spirally displaced in the axial direction, or the transfer tape 207 may not be transferred. Was unraveling.

Further, since the resilient piece 205 is in a cantilever state with its upper end being a free end, the bending or twisting force is applied to the resilient piece 205 by rotation of the supply reel 203 in addition to the resilient direction on the axis. If the transfer tool is used for a long period of time, the base of the resilient piece 205 and the protrusion 204 deteriorates, the resilience of the resilient piece 205 is reduced, and the supply reel 203 and the protrusion The fixing force to the transfer tape 2 decreases.
Even if the tension of 07 is not higher than a certain limit, the supply reel 203 and the gear 202 may not rotate in conjunction with each other, and the transfer tape 207 may gradually loosen.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, it is an object of the present invention to easily attach and detach a supply reel around which a transfer tape is wound at the time of replacement or assembly, and to install a transfer tool for a long period of time. It is another object of the present invention to provide a transfer tool in which a gear and a supply reel can be surely rotated in conjunction with each other when used, and a sliding mechanism can smoothly slide out as needed.

A hole 20 is provided in the center of the supply reel 4, and a transfer tape 6 is wound around the outer periphery. The transfer tape 6 fed from the supply reel 4 is disposed in front of the case 2. After passing through the leading end 21 of the transfer head 3, it is wound on the take-up reel 5.

In the present embodiment, the transfer tape 6 is a 5 mm wide correction tape in which a coating of a correction agent is provided on a film base material having a release property on the surface. Etc. can be provided on a tape of any width.

The first gear 12 is provided with an elastic tongue 22 at a position substantially intermediate between the outer edge and the center of the first gear 12.

Has a well-known ratchet structure.

FIG. 5 is a view showing a peripheral portion of a supply reel according to the first embodiment. The transfer tape is omitted.

In FIG. 5, the supply reel 4 has an intermediate member 27 disposed between the hole 20 provided in the supply reel 4 and the projection 15 of the first gear 12.

The intermediate member 27 is formed by four bulging surfaces 28 and four connecting portions 29, and the four bulging surfaces 28
Are connected to each other by a connecting portion 29 to form a substantially quadrangular shape.

The outer diameter of the projection 15 existing in the intermediate member 27 is larger than the diameter of an inscribed circle virtually inscribing the bulging surface 28, and the intermediate member 27 is attached to the bulging surface 28 of the first gear 12. The protrusion 15 is pressed and pressed from above against the resilience of the protruding portion 28, and the projection 15 is pinched and fixed by the resilience of the swelling surface 28.

Since the swelling surface 28 of the first embodiment is a surface swelling inward, it is needless to say that a sufficient elasticity can be obtained as compared with a plane or a surface swelling outward. In addition, since both sides of the bulging surface are connected to each other and the elastic part is in a two-sided state, even when the transfer tool is used for a long time, a stable resilient force is maintained compared to the cantilevered resilient piece. Can be done.

The connecting portion 29 is engaged with a concave portion 30 provided on the supply reel 4, and the intermediate member 27 is connected to the supply reel 4.
The structure is interlocked with the rotation of.

In FIG. 5, the recess 30 is formed between the projections 31 formed on the inner peripheral surface of the supply reel 4,
As another forming method, a concave portion may be formed by cutting off a part of the inner peripheral surface of the supply reel 4.

Further, by providing a gap between the concave portion 30 and the connecting portion 29 so that the supply reel 4 and the intermediate member 27 are loosely fitted, the supply reel 4 and the first gear 12 can be used during use.
Can be rotated in conjunction with
When replacing the reel or assembling the reel, the intermediate member 27 is connected to the protrusion 15.
The supply reel 4 can be easily attached / detached while remaining.

The connecting portion 29 is formed by connecting the intermediate member 27 to the protrusion 1.
5 is the portion where the deformation force is most generated by pinching the swelling surface 28, but since the adjacent swelling surface swells inward, its virtual internal angle is acute, and Endurance is better than obtuse angle.

In this embodiment, since the innermost part of the bulging surface 28 has a substantially line contact structure in which the outer surface of the projection 15 is linearly sandwiched and fixed vertically, the intermediate member 27 and the intermediate member 27 are stationary. The frictional force with the projection 15 is small, and the initial sliding of the sliding mechanism can be made smooth.

Further, lubricating oil can be injected between the protrusion 15 and the intermediate member 27 by using a gap (not shown) between the outer surface of the protrusion 15 and the inner surface of the intermediate member 27. It is possible to finely adjust the degree of sliding.

FIG. 6 is a view showing an intermediate member according to the first embodiment of the present invention. In FIG. 6, the intermediate member 27 has an outer dimension L of 8.44 mm, an outer lateral dimension W of 8.44 mm,
It is a molded article of polypropylene resin having a height H of 4.8 mm and a thickness t of 0.65 mm. In addition, the swelling surface 28
Is formed with an arc radius R of about 16 mm on the inner surface thereof, extends to the swelling surface 28 to form a connecting portion 29, and has a diameter D of an inscribed circle virtually inscribing the swelling surface 28 of 5.4 mm. The outer diameter of the protrusion 15 existing in the intermediate member 27 is 5.8 mm, the clamping allowance is 0.4 mm, and the transfer tape 6 has 22.5 g.
Although the projection 15 and the line contact surface portion of the swelling surface 28 are set so as to slide when the above-mentioned tension is generated, there is no particular restriction on the setting of each numerical value, and the setting is appropriately performed depending on various structures of the transfer tool. Just do it.

Although a polypropylene resin is used for the intermediate member as a specific example of the embodiment of the present invention, a relatively elastic resin such as polyacetal or polycarbonate, or a material having a known elasticity such as metal is used. Can be appropriately selected.

When the transfer was performed using the transfer tool of the first embodiment, when the tension of 22.5 g or more generated on the transfer tape 6 was generated, the intermediate member 27 and the protrusion 1 at rest were stopped.
Since the frictional force between the supply reel 4 and the transfer reel 5 was small, the supply reel 4 could slide out smoothly, and transfer could be performed smoothly.

FIG. 7 is a view of an intermediate member according to a second embodiment of the present invention. In FIG. 7, the intermediate member 32 includes a bulging surface 33 formed of two flat surfaces connected at an obtuse angle and a bulging surface 3.
3 is provided with a connecting portion 34 protruding from an extension line. Other than that, when the transfer tool was used in the same manner as in the first embodiment, the same effect as in the first embodiment could be obtained.

FIG. 8 is a view of an intermediate member according to a third embodiment of the present invention. In FIG. 8, the intermediate member 35 is formed by five bulging surfaces 36 and five connecting portions 37. In the present invention, the number of the bulging surface and the connecting portion forming the intermediate member is not particularly limited. However, in view of the size of a commonly used transfer tool and supply reel, the number of the bulging surface and the connecting portion is three to three. It is preferable to set the number in the range of six. If the number is set to seven or more, the side dimension of the bulging surface in the elastic direction becomes small, and it becomes impossible to obtain a sufficient elasticity.

[0053]

According to the transfer device of the present invention, the intermediate member disposed between the gear and the supply reel fixes the projection of the internal gear by resiliently holding and fixing the protrusion. And the supply reel rotate in conjunction with each other, and the connecting portion formed on the intermediate member is detachably engaged with the concave portion provided on the supply reel. The supply can be easily attached and detached while the member is left on the projection of the gear.

Also, since the intermediate member for holding and fixing the projection of the gear has a substantially line contact structure for holding and fixing the outer surface of the projection linearly over the upper and lower sides, the intermediate member and the intermediate member when stationary are stationary. Since the frictional force with the protrusion is small, the initial sliding of the sliding mechanism can be made smooth and smooth transfer can be performed.
