Description

  The present invention relates to a coating film transfer tool for transferring a corrected coating film, a paste coating film, and the like to a transfer surface.

  The coating film transfer tool is provided with a supply reel in which a transfer tape coated with a coating film is wound on a base tape in a case, and a transfer tape fed out from the supply reel is provided in a front end opening of the case. It is known that a base tape is wound around a take-up reel in a case after being supplied toward the head and transferring the coating film onto the transfer surface (see, for example, Patent Document 1).

  In such a film transfer tool, the rotation force of the supply reel is transmitted to the take-up reel via a power transmission mechanism by a gear train, and the take-up reel is rotated, whereby the base tape is transferred to the take-up reel. Winding up.

For this reason, as the transfer tape is fed out from the supply reel, the winding diameter of the transfer tape on the supply reel gradually decreases and the winding diameter of the base tape on the winding reel gradually increases.
Further, the rotation speed ratio of the take-up reel with respect to the rotation speed of the supply reel is determined by the number of gear teeth interposed between both reels. For this reason, as the winding diameter of the transfer tape on the take-up reel increases, the winding amount of the base tape on the take-up reel becomes larger than the transfer amount of the transfer tape on the supply reel. As a result, the tape tension between the take-up reel and the take-up reel is increased.

In particular, when winding a transfer tape having a length of, for example, 20 m to 40 m or more, in order to prevent the tape from loosening between the supply reel and the take-up reel, the take-up reel rotation speed is higher than the supply reel rotation speed. The tape tension between the supply reel and the take-up reel is increased.
For this reason, in the latter half of the tape winding, as the tape winding diameter on the take-up reel side becomes larger than the winding diameter on the supply reel side, the tensile force of the transfer tape fed out from the supply reel increases, and the transfer operation There was a problem that became heavy.
Japanese Patent Laying-Open No. 2005-47201 (FIG. 1)

  An object of the present invention is to provide a coating film transfer tool that can reduce the transfer operation even in the latter half of the tape winding.

The above-described problems are solved by the invention having the following configuration, as described in each claim in the section “Claims”.
(1) Provided in the case is a supply reel wound with a transfer tape coated with a coating film on a base tape, and the transfer tape fed from the supply reel is directed to a transfer head provided in the front end opening of the case. In the coating film transfer tool, the base tape that can be transferred and transferred onto the transfer surface, and the base tape that has been reversed through the transfer head after the transfer is wound into the case, Are wound around a plurality of take-up reels step by step by a tape take-up mechanism provided in the case.

(2) In the above item (1), the tape take-up mechanism includes a plurality of take-up reels arranged adjacent to each other in parallel with the take-up rotary shaft, and the final take-up reel from the primary take-up reel of each take-up reel. And switching means for shifting the base tape stepwise toward the take-up reel.

(3) In the above item (1), the tape take-up mechanism is arranged on the take-up rotating shaft so as to be movable in the axial direction, and the primary take-up reel is set in accordance with the width of the base tape. The rotating shaft portion that is exposed by the movement of the take-up reel by the change-over means is referred to as a secondary take-up reel.

(4) In the above item (1), the tape take-up mechanism is constituted by a plurality of take-up reels arranged adjacent to each other in parallel with the take-up rotation shaft, and the transfer head is formed on the final next roll of each take-up reel. In the initial stage of tape winding, the base tape is shifted toward the primary winding reel and wound up.

According to the present invention, the following effects can be obtained.
According to the first aspect of the invention, since the base tape is wound around the plurality of take-up reels step by step with the tape take-up mechanism provided in the case, the winding in the primary stage is performed. When the take-up reel tape take-up diameter is increased to some extent and the transfer operation feels heavy, the transfer operation is performed even in the latter half of the tape take-up by sequentially shifting the take-up of the base tape to the next take-up reel. Can be lightened.

  According to invention of Claim 2, there exists an effect similar to a previous term by a switching means.

  According to invention of Claim 3, there exists an effect similar to a previous term by a switching means.

  According to the invention described in claim 4, the transfer head is arranged so as to be offset toward the final take-up reel side of each take-up reel, and the base tape is offset toward the primary take-up reel side at the initial stage of tape take-up. Therefore, if the tape take-up diameter limit of the primary take-up reel is exceeded, the next take-up reel can be shifted in stages, thereby achieving the same effect as in the previous section. Play.

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