TECHNICAL FIELD OF THE INVENTION
The present invention relates to a coating film transfer device for transferring a coating film on a transfer tape to a paper surface or the like, and more particularly, to a drive mechanism of a transfer tape feeding portion and a substrate winding portion of the coating film transfer device. It is.
[0002]
[Prior art]
Various coating film transfer tools have been proposed for transferring a transfer tape to paper or the like. The coating film transfer tool generally includes a transfer tape, a feeding unit, a transfer unit, a winding unit, and a driving unit as internal components in a housing. The transfer tape is obtained by laminating a covering layer or an adhesive layer on a base material of thin paper or a plastic film, and includes a so-called correction tape, a marking tape, an adhesive tape, and the like. The transfer tape in the form of an elongated tape follows a path in the housing from the feeding section, through the transfer section, and to the winding section. The feeding section holds the transfer tape before the transfer, and generally winds and holds the transfer tape. The winding unit holds the base material after the transfer of the coating layer or the adhesive layer, and generally winds and holds the base material. The feeding section and the winding section rotate in conjunction with each other, and send the transfer tape from the feeding section to the winding section. The transfer portion is provided so as to protrude from the housing to transfer the transfer layer of the transfer tape to a transfer surface such as a paper surface.
[0003]
The winding unit or the feeding unit includes a reel for winding the transfer tape or the base material, and an interlocking rotating member having a shaft for supporting the reel. The reel of the winding section is a reel on which a transfer tape is wound in advance, and the reel of the feeding section is a section for sequentially winding the base material onto which the transfer layer has been transferred. The support shaft of the reel is a part for integrating the reel and the interlocking rotating unit. For this reason, the one in which the interlocking rotating unit and the reel are formed as one member is also used. As the interlocking rotation unit that interlocks the feeding unit and the winding unit, a mechanism that interlocks a rotating object such as a gear or a pulley is used. In order to synchronize the rotation of the feeding section and the winding section, a sliding mechanism using a friction member such as an O-ring or a projection is used. The driving method and the method of synchronizing the rotation are appropriately selected in combination. The housing is provided with shafts for supporting the winding section and the feeding section, respectively. The feeding portion and the winding portion may be arranged side by side in the housing, or may be arranged so as to overlap.
[0004]
A friction member such as an O-ring or an engagement claw is provided at a connection portion between the reel and the interlocking rotating member. When excessive rotational driving force is applied to the interlocking rotating part, only the reel supported by the shaft of the interlocking rotating member is rotated, and the transfer tape running between the feeding part and the winding part is slid so that it does not break. To escape the excess power. In some cases, the supporting shaft of the interlocking rotating member itself is used as a friction member to serve as a rotation synchronization means, while a connecting member as a friction member is interposed between the reel and the supporting shaft of the interlocking rotating member, and the connecting member is rotationally synchronized. There are also means.
[0005]
Between the reel and the support shaft of the interlocking rotating member, a connecting member is present, and as a sliding mechanism for synchronizing the feeding speed and the winding speed, a feeding cylinder wound with a coating film transfer tape uses an elastomer friction member. (See, for example, Patent Document 1). Examples of the elastomer friction member interposed between the reel and the support shaft of the interlocking rotating unit include an elastomer cylindrical bush and an elastomer O-ring. The force applied to both the cylindrical bush and the O-ring is absorbed by the elasticity of the elastomer, which is the material of the cylindrical bush, and an excessive force is released.
[0006]
The reel of the feeding part or take-up part is a double cylindrical body, the cylinder on the side that contacts the support shaft of the reel of the interlocking rotating part has lower mechanical strength than the cylinder on the side where the tape is wound, and as a sliding mechanism Some of them work (for example, see Patent Document 2). This is an engaged portion formed on a fitting inner peripheral surface of the winding core in a state of being engaged with an engaging portion formed on a fitting outer peripheral surface of the winding support shaft) or the feeding portion. Non-transmission when a relative rotational force greater than a set value is applied to the engaged portion formed on the fitting inner peripheral surface of the feeding core while being engaged with the engaging portion formed on the outer peripheral surface of the support shaft. While being configured to be elastically deformable in the state, the slip interlocking mechanism is configured with the engaged portion on the winding core side or the engaged portion on the feeding core side, and the engaged portion on the winding core side or The engaged portion on the feeding core side is configured to be weaker than the mechanical strength of the corresponding engaging portion on the winding support shaft side or the corresponding engaging portion on the feeding support shaft side.
[0007]
As a sliding mechanism for synchronizing rotation, a piece of the support shaft that contacts the reel of the interlocking rotating member plays a role, and in order to make the reel and the piece of the support shaft contact, the supporting shaft and the piece of the interlocking rotating member. (See, for example, Patent Document 3). This is because the supply reel is configured by rotatably engaging a delivery cylindrical portion with a boss portion of a drive gear rotatably supported on a first support shaft provided on the case, and winding the supply reel. The reel is configured by providing a driven gear meshing with the drive gear along the outer circumference of a winding cylindrical portion rotatably supported on a second support shaft provided in the case, and forming a boss portion of the drive gear. A main cylinder rotatably mounted on the first support shaft, and a plurality of pieces arranged side by side along the outer circumference of the main cylinder and further elastically contacting the inner peripheral surface of the feeding cylindrical portion. And a ring-shaped spacer is fitted between the piece and the main cylinder.

[Problems to be solved by the invention]
When the rotation synchronization means is integral with the interlocking rotating member, and the support shaft of the reel of the interlocking rotating member is a friction member, when the transfer tape is replaced with a new reel, the support shaft and the reel which are friction members are Will be different from before the replacement. For this reason, there is a problem that the frictional engagement between the support shaft and the reel changes every time the replacement is performed, and a constant feeling of use cannot be obtained. Similarly, when the reel also serves as a friction member, the same problem occurs because the frictional engagement between the reel and the support shaft changes by replacement. A similar problem occurs when a connecting member is interposed between the reel and the support shaft, the connecting member is a friction member, and a sliding mechanism is achieved by frictional engagement between the friction member and the reel. The present application provides a sliding friction mechanism that synchronizes rotation included in a drive mechanism and that does not change the effect of the sliding mechanism even when the reel is replaced.
