Description

本発明は、被転写物に転写フィルムを被覆する熱転写装置、前記熱転写装置に用いられる被転写物ホルダ、及び熱転写方法に関する。   The present invention relates to a thermal transfer apparatus that coats a transfer film on a transfer object, a transfer object holder used in the thermal transfer apparatus, and a thermal transfer method.

従来、家電製品、化粧品容器、装飾品などの種々の立体形状をした被転写物に絵柄や文字などの模様を付与するにあたり、被転写物に転写フィルムの絵柄層を熱転写する熱転写装置が利用されている(例えば、下記特許文献1参照)。   Conventionally, a thermal transfer device that thermally transfers a pattern layer of a transfer film to a transfer object has been used to give a pattern such as a pattern or a character to a transfer object having various three-dimensional shapes such as home appliances, cosmetic containers, and decorations. (For example, refer to Patent Document 1 below).

下記特許文献1に開示されている熱転写装置(絵付装置)は、ワークの表面に転写フィルムの絵柄層を熱転写する熱転写装置であって、内部にワークが載置され、上面に転写フィルムが配設されるチャンバ部材と、該チャンバ部材内の転写フィルムにより仕切られた空間を真空状態とすることにより、前記転写フィルムをワークの表面に密着させる真空引き装置と、前記チャンバ部材内の空間、または該チャンバ部材内に配置されてワークの周囲を囲う仕切壁部材内の空間に、ワークの表面に密着された転写フィルムにおける絵柄層の反ベースフィルム側の接着層をベースフィルム側から溶融可能な温度の蒸気を供給する蒸気供給装置と、を有することを特徴とするものである。   The thermal transfer device (picture attaching device) disclosed in Patent Document 1 below is a thermal transfer device that thermally transfers a pattern layer of a transfer film onto the surface of a work, in which the work is placed and a transfer film is disposed on the upper surface. The chamber member, and the space partitioned by the transfer film in the chamber member to be in a vacuum state, thereby bringing the transfer film into close contact with the surface of the workpiece, and the space in the chamber member, or the The adhesive layer on the side opposite to the base film side of the image layer of the transfer film in close contact with the surface of the work is melted from the base film side in the space in the partition wall member arranged in the chamber member and surrounding the work. And a steam supply device for supplying steam.

下記特許文献1に記載の熱転写装置によれば、ワークの表面形状に拘わらず、転写フィルムを密着させた面に対して、常に良好に絵付けすることが可能となる。   According to the thermal transfer device described in Patent Document 1 below, it is possible to always paint well on the surface to which the transfer film is adhered, regardless of the surface shape of the workpiece.

特開2011‐126263号公報JP 2011-126263 A

ところで、この種の熱転写装置を用いた熱転写の実行によって、前記ワーク(被転写物)に被覆される絵柄層は、前記転写フィルムにおける前記被転写物に被覆された部分(被覆部分)に存する絵柄層のみであり、前記被転写物に被覆されなかった余剰部分は、事実上、前記被転写物に対する絵付に寄与されない。   By the way, the pattern layer coated on the workpiece (transfer object) by executing thermal transfer using this type of thermal transfer apparatus is a pattern existing on the portion (covered part) covered with the transfer object on the transfer film. The surplus portion that is only the layer and is not covered with the transfer object does not contribute to the painting on the transfer object.

ここで、前記転写フィルムとして、ベースフィルムの片側面に、剥離層、絵柄層、及び接着層が順次積層された四層積層フィルムを用いた場合には、前記被転写物の表面に被覆させた前記転写フィルムから前記ベースフィルムを剥がし取ることによって、前記被転写物に転写フィルムの絵柄層に基づく絵付けをなすことができるため、余剰部分のトリミング工程は原則として必要ない。   Here, when a four-layer laminated film in which a release layer, a pattern layer, and an adhesive layer are sequentially laminated on one side of the base film is used as the transfer film, the surface of the transfer object is covered. Since the base film is peeled off from the transfer film, the transfer object can be painted based on the pattern layer of the transfer film. Therefore, the trimming process of the surplus portion is not necessary in principle.

しかしながら、前記転写フィルムとして、ベースフィルムの片側面に、絵柄層、及び接着層が順次積層された三層積層フィルムや、絵柄層の片側面に接着層が積層された二層積層フィルムなどのベースフィルムを剥離することなく絵付けする形式のフィルムを用いた場合、前記被覆部分から前記余剰部分を切り離すトリミング工程が必要になる。   However, as the transfer film, a base such as a three-layer laminated film in which a picture layer and an adhesive layer are sequentially laminated on one side of the base film, or a two-layer laminated film in which an adhesive layer is laminated on one side of the picture layer. In the case of using a film that can be painted without peeling off the film, a trimming step of separating the surplus portion from the covering portion is required.

現在、このトリミング工程は、熱転写の実行後、刃物やレーザーを用いた人的作業や、ロボットによる自動切断などによって実行されている。   Currently, this trimming process is performed by performing a human work using a blade or a laser, automatic cutting by a robot, or the like after performing thermal transfer.

しかしながら、刃物を用いたトリミング工程の実行は、大量の製品を処理するのに適しておらず、一方、レーザーによるトリミング工程の実行は、専用のレーザー装置の導入やレーザー使用の認可を受ける必要があるため、コスト高となる。又、ロボットによる自動切断についても、専用の機械装置を導入する必要があるため、やはりコスト高になる。   However, the execution of the trimming process using a blade is not suitable for processing a large amount of products. On the other hand, the execution of the trimming process using a laser requires the introduction of a dedicated laser device or the approval of laser use. This increases the cost. In addition, the automatic cutting by the robot is also expensive because it is necessary to introduce a dedicated machine.

本発明は、前記技術的課題に鑑みて完成されたものであり、被転写物に被覆された転写フィルムの被覆部分から、前記被転写物に被覆されなかった前記転写フィルムの余剰部分を好適に切り離すことができる新規な熱転写装置、前記熱転写装置に用いられる被転写物ホルダ、及び熱転写方法を提供することを目的とする。   The present invention has been completed in view of the above technical problem, and preferably a surplus portion of the transfer film that has not been coated on the transfer object from a coating portion of the transfer film that has been coated on the transfer object.

5 to 9 show a process of thermally transferring the pattern layer 302 of the transfer film 300 to the transfer object 100 by the apparatus 1 of the present invention. In the present invention, “thermal transfer” means that the surface (exposed surface) of the object to be transferred 100 is covered with the transfer film 300 by applying heat, and finally the pattern layer is applied to the object to be transferred 100. This means that painting according to the pattern 302 is applied.

‐作業室形成工程‐
本実施形態において、前記作業室形成工程を実行するにあたっては、まず、図5(a)に示すように、前記連結具16を介して前記本発明ホルダ50を装着する。本実施形態において、前記連結具16に対する前記本発明ホルダ50の装着は、前記連結具16に設けられた雌端子161と、前記本発明ホルダ50に設けられた前記雄端子52とを篏合させると共に、前記通気パイプ162と前記通気パイプ受孔541とを嵌合させることによって行った。これにより、前記雌端子161と前記雄端子52とが接続し、図5(b)に示す、前記電熱部材53と前記電力供給源164とを繋ぐ電気回路Cが形成される。
-Work chamber formation process-
In the present embodiment, when the work chamber forming step is executed, first, the holder 50 of the present invention is mounted via the connector 16 as shown in FIG. In the present embodiment, the attachment of the holder 50 of the present invention to the connector 16 is made to engage the female terminal 161 provided on the connector 16 and the male terminal 52 provided on the holder 50 of the present invention. At the same time, the ventilation pipe 162 and the ventilation pipe receiving hole 541 were fitted together. Thereby, the female terminal 161 and the male terminal 52 are connected, and an electric circuit C that connects the electric heating member 53 and the power supply source 164 shown in FIG. 5B is formed.

前記連結具16に前記本発明ホルダ50を装着した後、図6(a)に示すように、被転写物100を前記本発明ホルダ50に保持させる。本実施形態においては、前記被転写物100を前記本発明ホルダ50に保持させる際、前記ホルダ設置台12が、前記第一チャンバ部材10の開口端と面一になる位置まで上げられる。そして、前記本発明ホルダ50に前記被転写物100を保持させた後、前記ホルダ設置台12は、前記第一チャンバ部材10の底部に向かって下げられる。   After the present invention holder 50 is attached to the connector 16, the transferred object 100 is held by the present invention holder 50 as shown in FIG. In the present embodiment, when the transferred object 100 is held by the holder 50 of the present invention, the holder mounting base 12 is raised to a position flush with the open end of the first chamber member 10. Then, after the transferred object 100 is held by the holder 50 of the present invention, the holder mounting base 12 is lowered toward the bottom of the first chamber member 10.

前記被転写物100を前記本発明ホルダ50に保持させた後、前記第一チャンバ部材10の開口部を、前記転写フィルム300にて覆う。前記転写フィルム300は、接着層303側が前記第一チャンバ部材10内に臨むように配置される。   After the transfer object 100 is held by the holder 50 of the present invention, the opening of the first chamber member 10 is covered with the transfer film 300. The transfer film 300 is disposed such that the adhesive layer 303 side faces the first chamber member 10.

前記第一チャンバ部材10の開口部を、前記転写フィルム300にて覆った後、図6(b)に示すように、前記第一チャンバ部材10の開口部の端縁と、前記第二チャンバ部材20の開口部の端縁とを突き合わせることによって閉じられた作業室Sを形成する。前記作業室Sは、前記第一チャンバ部材10と前記第二チャンバ部材20との間に介在させた前記転写フィルム300によって、前記第一チャンバ部材10側となる第一室S1と、前記第二チャンバ部材20側となる第二室S2とに仕切られた状態となる。   After the opening of the first chamber member 10 is covered with the transfer film 300, as shown in FIG. 6B, the edge of the opening of the first chamber member 10 and the second chamber member A closed working chamber S is formed by abutting the edges of the 20 openings. The working chamber S includes a first chamber S1 on the first chamber member 10 side and a second chamber by the transfer film 300 interposed between the first chamber member 10 and the second chamber member 20. It will be in the state partitioned off by the 2nd chamber S2 used as the chamber member 20 side.

‐吸引工程‐
図7に示すように、前記吸引工程では、前記作業室形成工程によって形成された前記作業室Sに存する空気を吸引する。
-Suction process-
As shown in FIG. 7, in the suction step, air existing in the work chamber S formed by the work chamber formation step is sucked.

本実施形態において、前記吸引工程は、前記吸引装置30における前記分岐通路33、34各々に配置された吸引開閉弁35、36、及び前記バイパス通路37に配置されたバイパス開閉弁38を開き、前記吸引ポンプ31を作動させることによって、前記作業室Sに存する空気を吸引し、前記作業室Sを減圧することによって実行した(図1参照)。なお、前記バイパス通路37は、前記吸引工程の際に、前記第一室S1と前記第二室S2との間に圧力差が生じることを抑制する役割を担う。   In the present embodiment, the suction step opens the suction on / off valves 35 and 36 disposed in the branch passages 33 and 34 in the suction device 30 and the bypass on / off valve 38 disposed in the bypass passage 37, By operating the suction pump 31, the air in the working chamber S was sucked and the working chamber S was decompressed (see FIG. 1). The bypass passage 37 plays a role of suppressing a pressure difference between the first chamber S1 and the second chamber S2 during the suction process.

そして、前記作業室Sが十分に減圧された後、前記分岐通路33側に配された前記吸引開閉弁35、及び前記バイパス開閉弁38は閉じられる。一方、前記分岐通路34側に配された吸引開閉弁36は、開かれた状態のままとされる。即ち、前記吸引工程の実行後も、前記第一室S1の吸引は継続される。   Then, after the working chamber S is sufficiently decompressed, the suction on-off valve 35 and the bypass on-off valve 38 disposed on the branch passage 33 side are closed. On the other hand, the suction opening / closing valve 36 disposed on the branch passage 34 side is left open. That is, the suction of the first chamber S1 is continued even after the suction process is executed.

‐熱転写工程‐
前記熱転写工程では、前記第二室S2の内圧を前記第一室S1の内圧に対して正圧にすることによって、前記第一チャンバ部材10内に配された前記被転写物100に、前記転写フィルム300の絵柄層302を熱転写する。
-Thermal transfer process-
In the thermal transfer step, the internal pressure of the second chamber S2 is set to a positive pressure with respect to the internal pressure of the first chamber S1, thereby transferring the transfer to the transfer object 100 disposed in the first chamber member 10. The pattern layer 302 of the film 300 is thermally transferred.

本実施形態においては、前記熱転写工程を実行するにあたり、まず、図8(a)に示すように、前記熱盤25を前記転写フィルム300に向かって降下させ、前記熱盤25内に配されたヒータを作動させることによって、前記転写フィルム300を加熱し、軟化させた。   In the present embodiment, when executing the thermal transfer step, first, as shown in FIG. 8A, the hot platen 25 is lowered toward the transfer film 300 and arranged in the hot platen 25. The transfer film 300 was heated and softened by operating the heater.

又、本実施形態においては、前記転写フィルム300を軟化させた後、図8(b)に示すように、前記熱盤25を上げ、更に、前記ホルダ設置台12を前記第一チャンバ部材10の開口端と面一になる位置まで上げることによって、前記被転写物100を前記転写フィルム300と接触させた。   In the present embodiment, after the transfer film 300 is softened, as shown in FIG. 8B, the heating platen 25 is raised, and the holder installation base 12 is moved to the first chamber member 10. The transfer object 100 was brought into contact with the transfer film 300 by raising it to a position flush with the opening end.

この状態下、前記過熱蒸気発生装置41を作動させ、前記蒸気通路42に配置された蒸気開閉弁43を開き、前記第二室S2に向かって過熱蒸気を供給すれば、前記第二室S2の内圧が前記第一室S1の内圧に対して正圧となる(図1参照)。これより、過熱蒸気が供給された前記第二室S2と減圧状態にある前記第一室S1との間に生じた圧力差によって、図8(c)に示すように、前記転写フィルム300が、前記被転写物100の露出面に密着する。この際、前記被転写物100の露出面に密着した前記転写フィルム300は、前記第二室S2に供給された過熱蒸気の熱によって更に加熱されて、前記接着層303が溶融する。これにより、前記転写フィルム300が前記被転写物100の露出面に被覆される。   Under this condition, if the superheated steam generator 41 is operated, the steam on-off valve 43 disposed in the steam passage 42 is opened, and superheated steam is supplied toward the second chamber S2, the second chamber S2 The internal pressure becomes positive with respect to the internal pressure of the first chamber S1 (see FIG. 1). Thus, as shown in FIG. 8 (c), due to the pressure difference generated between the second chamber S2 supplied with superheated steam and the first chamber S1 in a reduced pressure state, the transfer film 300 is The transfer object 100 is in close contact with the exposed surface. At this time, the transfer film 300 in close contact with the exposed surface of the transfer object 100 is further heated by the heat of superheated steam supplied to the second chamber S2, and the adhesive layer 303 is melted. Thereby, the transfer film 300 is coated on the exposed surface of the transfer object 100.

‐トリミング工程‐
図9に示すように、本発明においては、前記熱転写工程に供された前記転写フィルム300のうち、前記被転写物100に被覆された部分を被覆部分300aといい、前記被転写物100に被覆されなかった部分を余剰部分300bと称する。そして、前記トリミング工程では、前記被覆部分300aと、前記余剰部分300bと、を切り離す。
-Trimming process-
As shown in FIG. 9, in the present invention, a portion of the transfer film 300 that has been subjected to the thermal transfer process and that is covered with the transfer object 100 is referred to as a covering portion 300a, and the transfer object 100 is covered. The part that has not been performed is referred to as a surplus part 300b. In the trimming step, the covering portion 300a and the surplus portion 300b are separated.

本実施形態においては、前記トリミング工程を実行するにあたり、前記電力供給源164から前記電気回路Cに電力を供給する(図5(b)参照)。前記電気回路Cに供給された電力は、前記トランス163によって低電圧大電流となされ、前記電熱部材53に電熱を生じさせる。   In the present embodiment, power is supplied from the power supply source 164 to the electric circuit C when performing the trimming process (see FIG. 5B). The electric power supplied to the electric circuit C is converted into a low voltage and large current by the transformer 163, and electric heat is generated in the electric heating member 53.

そして、前記電熱部材53は、前記被覆部分300aと前記余剰部分300bとの境界となる位置に沿って配されているため、図9(b)に示すように、前記転写フィルム300は、前記境界に沿って切断される。なお、本実施形態においては、前記電気回路Cの構築の都合上、前記トリミング工程の実行によって、前記被覆部分300aと前記余剰部分300bとが、境界の一部を残して切り離されるが、本発明において「切り離す」とは、このような境界の一部を残した状態で前記転写フィルム300を切断することも含まれるものとする。   And since the said electrothermal member 53 is distribute | arranged along the position used as the boundary of the said coating | coated part 300a and the said excess part 300b, as shown in FIG.9 (b), the said transfer film 300 is the said boundary. Is cut along. In the present embodiment, for the convenience of the construction of the electric circuit C, the trimming process is performed to separate the covering portion 300a and the surplus portion 300b leaving a part of the boundary. In this case, “separating” includes cutting the transfer film 300 while leaving a part of the boundary.

前記トリミング工程の実行後、前記作業室Sを開放し、切り離されなかった境界の一部を刃物等で切り離せば、図9(c)に示す、転写体110が得られる。   After the trimming step is performed, the work chamber S is opened, and a part of the boundary that has not been separated is separated with a blade or the like, whereby a transfer body 110 shown in FIG. 9C is obtained.

即ち、本発明によれば、本発明装置1による熱転写の実行時における工程の一環として、前記被転写物100に被覆された前記転写フィルム300の被覆部分300aから、前記被転写物100に被覆されなかった前記転写フィルム300の余剰部分300bを好適に切り離すことができる。   That is, according to the present invention, as a part of the process at the time of performing thermal transfer by the apparatus 1 of the present invention, the transfer object 100 is covered from the covering portion 300a of the transfer film 300 covered with the transfer object 100. The excess portion 300b of the transfer film 300 that was not present can be suitably cut off.

ところで、本実施形態においては、抵抗加熱による電熱によって前記トリミング工程を実行しているが、必ずしも電熱は抵抗加熱によるものとは限られない。例えば、図10に示す電気回路Cように、抵抗加熱による電熱に替えて、誘導加熱による電熱が生じるものとすることもできる。誘導加熱による電熱によれば、前記被覆部分300aと前記余剰部分300bとを、境界に沿って完全に切り離すこともできる。   By the way, in this embodiment, although the said trimming process is performed by the electric heating by resistance heating, electric heating is not necessarily by resistance heating. For example, as in an electric circuit C shown in FIG. 10, electric heating by induction heating may be generated instead of electric heating by resistance heating. According to the electric heating by induction heating, the covering portion 300a and the surplus portion 300b can be completely separated along the boundary.

又、抵抗加熱による電熱によっても、例えば、電気回路Cを図11に示すような構造とすれば、前記被覆部分300aと前記余剰部分300bとを、境界に沿って完全に切り離すことができる。この電気回路Cの構造を更に詳しく説明すると、前記電気回路Cは、電熱部材53の根元部分において、金属などの熱伝導部材531を差し渡した構造を有する。又、前記電気回路Cにおいては、ショートが生じないように前記電熱部材53と前記熱伝導部材531との接点に、絶縁体532が介在されている。即ち、この電気回路Cは、前記電熱部材53に電熱を生じさせると、係る電熱が、前記熱伝導部材531に伝導する仕組みとなされている。これより、前記電熱部材53と前記熱伝導部材531との協働によって、前記被覆部分300aと前記余剰部分300bとを、境界に沿って完全に切り離すことができる。   Further, even by electric heating by resistance heating, for example, if the electric circuit C has a structure as shown in FIG. 11, the covering portion 300a and the surplus portion 300b can be completely separated along the boundary. The structure of the electric circuit C will be described in more detail. The electric circuit C has a structure in which a heat conducting member 531 such as a metal is passed at the base portion of the electric heating member 53. In the electric circuit C, an insulator 532 is interposed at the contact point between the electric heating member 53 and the heat conducting member 531 so that no short circuit occurs. That is, the electric circuit C is configured such that when electric heat is generated in the electric heating member 53, the electric heat is conducted to the heat conducting member 531. Thus, the covering portion 300a and the surplus portion 300b can be completely separated along the boundary by the cooperation of the electric heating member 53 and the heat conducting member 531.

なお、前記電熱部材53に電熱を生じさせる電熱の温度は、前記転写フィルム300の種類に応じて適宜決定されるものであり、特に限定されるものではないが、130〜200度の範囲(より好ましくは、160〜180度)とすることが好ましい。又、前記電熱部材53から生じる電熱は、サーモスタットなどの監視手段により温度管理することが好ましい。   The temperature of the electric heat that generates electric heat in the electric heating member 53 is appropriately determined according to the type of the transfer film 300 and is not particularly limited, but is in the range of 130 to 200 degrees (more Preferably, it is preferable to set it as 160-180 degree | times. The electric heat generated from the electric heating member 53 is preferably temperature-controlled by a monitoring means such as a thermostat.

又、本実施形態においては、前記トリミング工程の際、前記第一室S1の吸引を継続しているが、本発明においては、前記トリミング工程の実行の際に、必ずしも前記第一室S1の吸引を継続する必要はない。但し、本実施形態のように、前記第一室S1の吸引を継続することによって、前記第二室S2の内圧を前記第一室S1の内圧に対して正圧にした状態で、前記トリミング工程を実行すれば、前記転写フィルム300の境界部分が前記電熱部材53に押し付けられた状態となるため、境界部分の切断が速やかとなる。特に、本実施形態においては、前記本発明ホルダ50に前記通気路54を設け、前記通気孔542の開口端を前記電熱部材53の下部に配列しているから、前記転写フィルム300の境界部分を前記電熱部材53に押し付ける作用がより高くなる。   In the present embodiment, the suction of the first chamber S1 is continued during the trimming step. However, in the present invention, the suction of the first chamber S1 is not necessarily performed when the trimming step is performed. There is no need to continue. However, as in the present embodiment, the trimming step is performed in a state where the internal pressure of the second chamber S2 is made positive with respect to the internal pressure of the first chamber S1 by continuing the suction of the first chamber S1. If this is executed, the boundary portion of the transfer film 300 is pressed against the electric heating member 53, so that the boundary portion is quickly cut. In particular, in this embodiment, the air passage 54 is provided in the holder 50 of the present invention, and the open ends of the air holes 542 are arranged below the electric heating member 53. The action of pressing against the electric heating member 53 becomes higher.

そして、図12に示すように、前記転写フィルム300の境界部分を前記電熱部材53に押し付ける作用は、前記電熱部材53の直近に沿って、前記通気孔542を配列させることによって一層向上する。   As shown in FIG. 12, the action of pressing the boundary portion of the transfer film 300 against the electric heating member 53 is further improved by arranging the vent holes 542 in the immediate vicinity of the electric heating member 53.

又、このように、前記通気孔542の配列を前記電熱部材53の直近に沿うものとすれば、電熱により前記転写フィルム300が切断された際、前記第二チャンバ部材20内に存する媒体が、前記通気路54を通じて、前記第一チャンバ部材10内に流れ込む。この前記転写フィルム300の切断後に生じる媒体の流れは、前記電熱部材53を冷却する効果を生じさせ、もって、前記転写フィルム300の切断箇所が過剰に熱せられることを抑制する作用が生じる。   Further, in this way, if the arrangement of the vent holes 542 is along the immediate vicinity of the electric heating member 53, when the transfer film 300 is cut by electric heating, the medium existing in the second chamber member 20 is The air flows into the first chamber member 10 through the air passage 54. The flow of the medium generated after the transfer film 300 is cut causes an effect of cooling the electric heating member 53, and thus has an effect of suppressing the heating of the cut portion of the transfer film 300.

ところで、本実施形態においては、前記トリミング工程の後、前記転写体110を取り出しているが、図13に示すように、前記本発明ホルダ50の上面から出没可能となされた押し上げ部材60を備えてなる本発明装置1を用いれば、前記転写体110の取り出し作業が容易になる。   By the way, in this embodiment, after the trimming step, the transfer body 110 is taken out. As shown in FIG. 13, a push-up member 60 that can be projected and retracted from the upper surface of the holder 50 of the present invention is provided. If the present invention apparatus 1 is used, the transfer operation of the transfer body 110 becomes easy.

更に詳しく説明すると、図13に示す本発明装置1は、前記本発明ホルダ50に対し、上下方向に向かって貫通する貫通孔が二箇所設けられてなり、各貫通孔それぞれに、前記押し上げ部材60が挿通されている。   More specifically, the device 1 of the present invention shown in FIG. 13 has two through holes penetrating in the vertical direction with respect to the holder 50 of the present invention, and the push-up member 60 is provided in each through hole. Is inserted.

又、前記押し上げ部材60は、前記ホルダ設置台12の下部に配された押し上げシリンダ61によって上下動可能な仕組みとなされている。従って、前記押し上げシリンダ61のロッドを伸ばせば、前記押し上げ部材60の上端が、前記本発明ホルダ50の上面から突出し、前記押し上げシリンダ61のロッドを縮めれば、前記押し上げ部材60の上端が、前記本発明ホルダ50の上面から没する。なお、本発明方法の実行の際、前記押し上げ部材60は、前記押し上げ部材60の上端が、前記本発明ホルダ50の上面から没した状態となされる。   Further, the push-up member 60 can be moved up and down by a push-up cylinder 61 arranged at the lower part of the holder installation base 12. Accordingly, when the rod of the push-up cylinder 61 is extended, the upper end of the push-up member 60 protrudes from the upper surface of the holder 50 of the present invention, and when the rod of the push-up cylinder 61 is contracted, the upper end of the push-up member 60 is It sinks from the upper surface of the holder 50 of the present invention. When the method of the present invention is performed, the push-up member 60 is in a state where the upper end of the push-up member 60 is submerged from the upper surface of the holder 50 of the present invention.

そして、前記押し上げ部材60を具備してなる本発明装置1を用いて、本発明方法を実行した後、前記押し上げ部材60の上端を、前記本発明ホルダ50の上面から突出させれば、図14に示すように、前記転写体110は、前記本発明ホルダ50から浮き上がる。   Then, after executing the method of the present invention using the device 1 of the present invention comprising the push-up member 60, if the upper end of the push-up member 60 is projected from the upper surface of the holder 50 of the present invention, FIG. As shown, the transfer body 110 is lifted from the holder 50 of the present invention.

これにより、前記転写体110の取り出し作業が容易になる。なお、前記転写体110の取り出し作業は、人的作業によって行っても良いが、ロボットによって自動的に行うことが好ましい。   This facilitates the work of taking out the transfer body 110. The transfer operation of the transfer body 110 may be performed manually, but is preferably performed automatically by a robot.

本実施形態においては、前記転写フィルム300として、ベースフィルム301の片側面に、絵柄層302、及び接着層303が順次積層された三層積層フィルムを用いているが、前記転写フィルム300としては、絵柄層302の片側面に接着層303が積層された二層積層フィルムを用いても良い。   In the present embodiment, as the transfer film 300, a three-layer laminated film in which a pattern layer 302 and an adhesive layer 303 are sequentially laminated on one side of the base film 301 is used. A two-layer laminated film in which the adhesive layer 303 is laminated on one side of the pattern layer 302 may be used.

又、本発明は、前記転写フィルム300としては、ベースフィルム301と絵柄層302との間に剥離層を介在させた四層積層フィルムを用いることを否定するものではない。前記転写フィルム300として、このような四層積層フィルムを用いた場合、前記被転写物100の表面に被覆させた前記転写フィルム300から前記ベースフィルム301を剥がし取ることによって、前記被転写物100に前記転写フィルム300の絵柄層302に基づく絵付けをなすことができるため、余剰部分300bのトリミング工程は原則として必要ないものとされるが、この場合においても前記トリミング工程を実行すれば、切断された境界部分がより美麗となる利点がある。   Further, the present invention does not deny that the transfer film 300 is a four-layer laminated film in which a release layer is interposed between the base film 301 and the pattern layer 302. When such a four-layer laminated film is used as the transfer film 300, the base film 301 is peeled off from the transfer film 300 coated on the surface of the transfer object 100, whereby the transfer object 100 is transferred to the transfer object 100. Since painting based on the pattern layer 302 of the transfer film 300 can be performed, the trimming process of the surplus portion 300b is not necessary in principle. However, in this case as well, if the trimming process is performed, the surplus portion 300b is cut. There is an advantage that the border portion becomes more beautiful.

更に、本実施形態においては、前記電熱部材53につき、線状の導電部材を用いているが、例えば、帯状の導電部材を前記電熱部材53として用いても良い。   Furthermore, in the present embodiment, a linear conductive member is used for the electric heating member 53, but, for example, a strip-shaped conductive member may be used as the electric heating member 53.

加えて、本実施形態においては、前記本発明ホルダ50を着脱式としているが、前記本発明ホルダ50は、前記第一チャンバ部材10内に固定されたものとしても良い。   In addition, in the present embodiment, the holder 50 of the present invention is detachable, but the holder 50 of the present invention may be fixed in the first chamber member 10.

又、本実施形態においては、前記吸引工程の際に、前記第一室S1と前記第二室S2との間に圧力差が生じることを抑制すべく、前記分岐通路33、34を連絡するバイパス通路37を備えているが、このバイパス通路37は、例えば、前記第一チャンバ部材10と前記第二チャンバ部材20とを直接連絡するようにして取り付けても良い。   Further, in the present embodiment, in order to suppress a pressure difference between the first chamber S1 and the second chamber S2 during the suction process, the bypass that communicates the branch passages 33 and 34 is bypassed. Although the passage 37 is provided, the bypass passage 37 may be attached so as to directly connect the first chamber member 10 and the second chamber member 20, for example.
