Abstract

PROBLEM TO BE SOLVED: To solve such a problem that a past coating film transfer tool is demanded to stop after slight move, in the transfer of the limited short length, while maintaining a posture of a transfer tool, and a deliberate and careful operation is needed.SOLUTION: Transfer is performed while rocking a transfer arm that pivotally supports a transfer roller and is made rockable, and the transfer is made to finish by inhibiting the rotation of the transfer roller at the rocking end. Moreover, a long, continuous transfer is enabled, when a user generates detectable load on the way of rocking, and the user pulls forward while maintaining the rocking angle at that time.

Description

  The present invention relates to a coating film transfer tool for transferring a coating film by an operation that a user holds in his / her hand and sweeps it while pressing it against a surface to be transferred.

A coating film transfer tool for transferring an adhesive or a coating film that conceals characters or the like is widely used.
In these coating film transfer tools, a method is often used in which a tape base material coated with a rotating transfer roller is pressed and transferred from the side opposite to the coating film to the transfer surface.

  During use, tilt the coating film transfer tool by hand and pull it forward while applying the transfer roller protruding downward to the surface to be transferred. That is, the transfer roller is rotated while pressing the surface of the tape substrate on which the coating film is not applied to the surface to be transferred, so that the coating film on the opposite surface is transferred. This requires a delicate operation that sweeps forward while maintaining the pressing posture and stops with a slight amount of movement.

  In order to solve the above problems, there has been proposed that a transfer arm capable of swinging is provided and the transfer roller pivotally supported at the tip rotates and swings simultaneously to assist the transfer.

  In the utility model registration No. 3137816 (Patent Document 1), the contact with the transfer surface of the transfer roller is changed by the swing, so that a slightly short transfer is possible by simply pushing up and down without sweeping. Has been made.

  Japanese Laid-Open Patent Publication No. 2012-66561 (Patent Document 2) proposes that the transfer roller is forcibly driven by swinging to assist and facilitate the sweep operation.

Utility Model Registration No. 3137816 JP 2012-66561 A

  However, in the first proposal (Patent Document 1), the operation of simply pushing up and down causes the transfer length to be very short and is not practical.

  In the second proposal (Patent Document 2), it is necessary to dispose a rotation transmitting means for rotationally driving the transfer roller and a clutch for freely rotating the transfer roller on the transfer arm. Therefore, it is inevitable that the configuration is complicated.

  As described above, the conventionally known methods are not practical and have a complicated configuration, which has an influence on cost and shape and is not realistic.

  SUMMARY OF THE INVENTION An object of the present invention is to make it possible to reliably realize a transfer with a short practical length with a simple configuration.

  In the present invention, the transfer arm that pivotally supports the transfer roller can be swung. When the user swings the transfer arm to a predetermined angle against the force of the return means, the swing is stopped and the transfer roller is rotated at the same time. Since it is blocked, no further transfer takes place.

  In the middle of a predetermined angle, the load means applies a load against the swing of the transfer arm, and after the user detects the load, pull the main body while maintaining the swing angle without applying any further pressing force. Long continuous transfer is possible.

  According to the solution means of the present invention, short transfer is easy, and short transfer and long continuous transfer can be easily used properly.

  That is, when the user presses the transfer roller against a portion where transfer is to be started while tilting the coating film transfer tool toward the front, the transfer is started while the transfer arm starts to swing. At this time, the tape base material with the coating film is pulled out from the supply reel by the amount of movement of the transfer roller due to the swing.

  When the tape substrate is pulled out, the transfer roller in contact with the surface opposite to the coating film of the tape substrate is rotated. Generally, the thickness of the tape substrate is 10 microns or less, and the surface of the transfer roller is an elastic material with a high coefficient of friction such as silicon, so if the transfer roller width is wider than the tape substrate width, As a result of contact with the transfer surface on the outside and transmission of the rotation, a force to move the coating film transfer tool to the front is generated, and even if the user does not consciously move it to the front, it will be swept naturally to the front. The

  If you want to lengthen the transfer length, you can move it consciously by pulling it forward.

  When the swing reaches a certain angle, the pressing force by the load means increases rapidly.

  At this time, if a force is further applied and pressed, the swing reaches a predetermined angle, the rotation of the transfer roller is prevented, and the transfer roller cannot be pulled forward, and the transfer is completed at this point.

  If you feel a sudden increase in the pressing force, if you pull it forward while maintaining the pressing force, the swing will stay at the position in front of the specified angle and the rotation of the transfer roller will not be blocked, so long continuous transfer is possible .

  Even in the case of long continuous transfer, if the coating film transfer tool is strongly pressed lastly, the swing reaches a predetermined angle and rotation of the transfer roller is prevented, so that the transfer can be completed reliably.

  As described above, the effect of the present invention in which the transfer length is freely determined by the arrangement of the pressing force and the forward pulling motion is clear.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, the tape path 5b and the relationship between transfer and sweep will be described with reference to FIGS.

  Although FIG. 4 shows the first embodiment, the swinging of the tape path 5b and the transfer arm 8 is the same in the second embodiment. An entrance guide roller 6 and an exit guide roller 7 are disposed in the middle of the tape path 5b that is wound around the transfer roller 9 away from the tape roll 5a and contacts the tape roll 5a again.

  When the transfer arm 8 swings clockwise by a predetermined angle of 36 degrees as indicated by a two-dot chain line, the right side of the tape path 5b is bent by the inlet guide roller 6 and thus does not loosen. Further, the pre-swing total tape base length LA and the post-swing total tape base length LB shown in FIGS. 5 and 6 can be suppressed to the same level by the exit guide roller.

  In comparison between FIG. 5 showing the tape path 5b before swinging and FIG. 6 showing the tape path 5b after swinging, the length of the tape base material which is separated from the entrance guide roller 6 and reaches the transfer roller 9 is Whereas the front entrance tape base length SA is 40.2 mm, the post-rocking tape base length SB is 46.8 mm, and the difference 6.6 mm is wound from the tape roll 5 a wound around the supply reel 3. It is paid out.

  As described above, the length of the tape base material from which the transfer roller 9 is wound away from the entrance guide roller 6 and the used tape base material reaches the tape roll 5a again is 114. Whereas it is 3 mm, the tape base length LB after swinging is not so different as 115.2 mm. Therefore, the tape path is not loosened or tensioned by swinging.

  If the coating film transfer tool 1 is not intentionally swept forward (to the right in FIG. 7) while the coating film transfer tool 1 is pressed against the transfer surface 10, the above-mentioned transfer of the length of 6.6 mm is performed by swinging. At that time, as shown in FIG. 7, the horizontal movement amount of the portion held by the hand of the coating film transfer tool 1 reaches 21.6 mm.

  FIG. 8 is a graph showing the above relationship. The diagonal lines shown in this graph require that the amount of each axis is not 1: 1, that is, 45 °, but that the horizontal movement amount of about three times or more the transfer length is pulled by hand to move it.

  In other words, with a short transfer of around 6.6 mm, the rate of increase in the transfer length with respect to the amount of horizontal movement of the portion held by the hand of the coating film transfer tool 1 is low, that is, the sensitivity is low. And can be operated easily.

  In the graph showing the transfer arm repulsive force and the transfer arm swing angle in FIG. In the embodiment of the present invention, the predetermined angle of swing is 36 degrees.

In FIG. 9, the user detects the rising part of the load sudden increase part P,
Thereafter, the state in which the pressing force is not increased and the long continuous transfer is performed by pulling forward while maintaining the swing angle is shown. The rising point of the load sudden increase portion P in FIG. Match. On the right side of the sweep inflection point S, the oblique line in FIG.

  As described above, if the swing is applied, short transfer can be easily performed, and there is no adverse effect on long continuous transfer. The present invention further expands this advantage by adding blocking means Y and load means Z.

  1 to 4 and FIGS. 11 to 15 show a first embodiment of the present invention.

  As shown in FIG. 1, the coating film transfer tool 1 having all the parts built in the cover 1a is used in a state of being tilted forward (upper right direction on the paper surface).

FIG. 2 shows the structure of this embodiment by disassembling the main part.
A supply reel 3 and a take-up reel 4 are disposed on the lower base 22 and rotate synchronously. Although this synchronous rotation is also provided with a friction slip mechanism, it is not shown because it is a known means.
In addition, the inlet guide roller 6 and the outlet guide roller 7 are also pivotally supported by the lower base 22.
Although the tape roll 5 a and the tape path 5 b are also drawn in a shifted manner, the tape roll 5 a is originally integral with the supply reel 4.

  The transfer roller 9 is integrally formed by fitting a tube 9b made of an elastic material such as silicon on a shaft 9a, and is supported by a transfer roller shaft support portion 8e of the transfer arm 8. The transfer arm 8 is pivotally attached to the lower base 22 at its swing center shaft 8a. These parts are sandwiched and integrated by the lower base 22 and the upper base 21, and the cover 1a is covered.

  FIG. 3 shows a state in which the cover 1a is removed. FIG. 4 shows an internal component arrangement in which the upper base 21 is further removed from FIG. The two-dot chain line in FIG. 4 represents a state in which the transfer arm 8 is swung to a predetermined angle. In this embodiment, the predetermined angle is 36 degrees. Although not shown, the predetermined angle is defined between the transfer arm 8 and the base 2 by a long hole and a boss.

11 and 12 show the shape of the transfer arm 8 of this embodiment.
In the transfer arm 8, a return spring portion 8f extends upward from a body portion 8b outside the swinging central shaft 8a. In addition, a symmetrical arm portion 8c extends downward from the body portion 8b, and a symmetrical rotation blocking arm portion 8i having elasticity extends inside thereof. Further, a rotation prevention abutting portion 8j protrudes in the middle of the rotation prevention arm portion 8i. The other end of the rotation prevention arm 8i is connected to the left and right to form a rotation prevention 8k at the tip. The surface of the rotation preventing portion 8k has an uneven shape.

The return means X and the blocking means Y of this embodiment will be described with reference to FIGS.
In FIGS. 14 and 15, the lower base 22 is drawn apart. A spring receiving boss 21f provided on the inner surface of the upper base 21 is in contact with the tip of the return spring portion 8f. When the state before the swing in FIG. 14 shifts to the state after the swing in FIG. 15, the return spring portion 8f is elastically deformed by the spring receiving boss 21f. The transfer arm 8 is restored by the spring force stored at this time.
The return means X is constituted by these two points.

  When the transfer arm 8 swings, the rotation blocking contact portion 8j is pressed against both the upper protruding portion 21a of the upper base 21 and the lower protruding portion 22a of the lower base 22, and the rotation blocking arm portion 8i is elastically deformed. Then, the rotation prevention contact portion 8j pushes the tube 9b of the transfer roller 9 to prevent the transfer roller 9 from rotating. The blocking means Y is realized as described above.

  In FIG. 13, an elastic arm portion 8g is formed on the side surface of the symmetrically symmetrical arm portion 8b, and a load protrusion 8h protrudes from the tip. An upper projection 21b is provided on the inner surface of the upper base, and a lower projection 22b is provided on the inner surface of the lower base 22, which are in contact with the elastic arm portion 8g. When the transfer arm 8 swings and the load protrusion 8h abuts on and gets over the upper protrusion 21b and the lower protrusion 22b, the elastic arm 8g is elastically deformed and a load is generated. The load means Z is implement | achieved by the above.

  17 to 20 show a second embodiment of the present invention, and the return means X, blocking means Y, and load means Z are basically the same principle as in the first embodiment.

  As shown in FIG. 19, the return means X includes a return spring portion 8f extending from a connecting portion 8d that bridges the left and right arm portions 8c, an upper base upper spring receiving boss 21e, and a lower base 22 lower spring. By receiving boss 22e.

The blocking means Y is realized as described above.

  With respect to the load means Z, the load protrusion 8 h provided on the inner surface of the arm portion 8 c of the transfer arm 8 is provided on the upper bent portion 21 g of the upper load arm portion 21 f provided on the upper base 21 and the lower portion provided on the lower base 22. When contacting and getting over the lower bent portion 22g of the load arm portion 22f, the upper load arm portion 21f and the lower load arm portion 22f are elastically deformed to generate a load. The load means Z is implement | achieved by the above.

  Although two embodiments have been described above, these parts prevent the increase in the number of parts by making a part of the member elastically deformable. Other configurations and shapes are possible without departing from the spirit of the present invention.
