Description

本発明は、連続回転式の昇華転写機の加熱ローラに関するものである。 The present invention relates to a heating roller of a continuously rotating sublimation transfer machine.

連続回転式の昇華転写機は、加熱ローラに巻き付けられた搬送ベルトによって、帯状の転写シートと帯状の被転写物とを重ね連続的に送りながら、前記加熱ローラに接して通過する際の加熱状態下で、転写シートの図柄を被転写物に連続的に転写する装置であり、この種の昇華転写機による転写の品質向上の重要な要素の一つとして、加熱ローラのローラ筒外周面の温度均一性の確保がある。 The continuously rotating sublimation transfer machine is in a heated state when the band-shaped transfer sheet and the band-shaped object to be transferred are continuously fed by the transport belt wound around the heating roller while being in contact with the heating roller. Below, it is a device that continuously transfers the design of the transfer sheet to the object to be transferred, and one of the important factors for improving the quality of transfer by this type of sublimation transfer machine is the temperature of the outer peripheral surface of the roller cylinder of the heating roller. There is a guarantee of uniformity.

従来の加熱ローラは、そのローラ筒の内周面側に、全長にわたって発熱する複数本の棒状ヒータ(以下、全部発熱棒状ヒータともいいう)の長手方向を筒軸方向に向けた状態で、ローラ筒の周方向に当該ローラ筒外周面の温度が均一となるよう等間隔で均等に配設された構造であった。
しかしながら、長さ方向の全長にわたってその全部が発熱する全部発熱棒状ヒータをローラ筒の筒軸方向に配設した構造であるため、ローラ筒外周面の中央側が中央に近くなる程高温となり、相対的にローラ筒外周面の両端側が両端側に近くなる程温度が低温となってしまうという、温度の不均一性を解消できず、加熱ローラの外周面の温度均一性の確保に難点があった。 In a conventional heating roller, a roller cylinder is provided with the longitudinal direction of a plurality of rod-shaped heaters (hereinafter, also referred to as all heating rod-shaped heaters) that generate heat over the entire length directed toward the cylinder axis on the inner peripheral surface side of the roller cylinder. The structure was evenly arranged at equal intervals so that the temperature of the outer peripheral surface of the roller cylinder was uniform in the circumferential direction of the roller cylinder.
However, since the structure is such that all the heating rod-shaped heaters that generate heat over the entire length in the length direction are arranged in the direction of the cylinder axis of the roller cylinder, the temperature becomes higher as the center side of the outer peripheral surface of the roller cylinder becomes closer to the center, which is relative. In addition, the temperature becomes lower as both ends of the outer peripheral surface of the roller cylinder become closer to both ends, which makes it impossible to eliminate the temperature non-uniformity, and there is a problem in ensuring the temperature uniformity of the outer peripheral surface of the heating roller.

従来、この難点を克服する一つの手段として、ローラ筒の筒内にオイルを充填してこれを加熱し、ローラ筒外周面の温度均一性を確保しようとする手段が提案されている。
しかし、この手段では、オイルを所要温度に加熱する迄に長時間を要するため、即座に転写作業を開始することができないという作業効率の悪さがあり、劣化したオイルの交換も必要で、オイル交換の度に、劣化オイルの破棄という環境破壊に繋がる問題がある上、オイル充填により重量が増加し、ランニングコストも高くなってしまうという不都合があった。 Conventionally, as one means for overcoming this difficulty, a means for filling the inside of the roller cylinder with oil and heating the oil to ensure the temperature uniformity of the outer peripheral surface of the roller cylinder has been proposed.
However, with this method, it takes a long time to heat the oil to the required temperature, so there is a poor work efficiency that the transfer work cannot be started immediately, and it is necessary to replace the deteriorated oil. In addition to the problem of discarding deteriorated oil, which leads to environmental destruction, there is the inconvenience that the weight increases due to oil filling and the running cost also increases.

本発明は、上記課題の解決を目的とすると共に、従来に較べてより温度均一性の高い連続昇華転写用加熱ローラとそれを用いた連続昇華転写機の提供を目的とする。 An object of the present invention is to solve the above problems, and to provide a heating roller for continuous sublimation transfer having higher temperature uniformity than conventional ones and a continuous sublimation transfer machine using the same.

図1及び図２において、実施例1の連続昇華転写用加熱ローラは、全長にわたって発熱する複数本の全部発熱棒状ヒータ１１と全長の一部の長さ領域のみを発熱部とした複数本の部分発熱棒状ヒータとしての両側端部発熱棒状ヒータ１２とを、加熱ローラ１のローラ筒２の内周面側に、ローラ筒２の周方向に向けて、ローラ筒２の外周面が均一に発熱されるように交互的に組合せて均等に配設したものである。 In FIGS. 1 and 2, the heating roller for continuous sublimation transfer according to the first embodiment has a plurality of all-heating rod-shaped heaters 11 that generate heat over the entire length and a plurality of portions having only a part of the total length region as a heat generating portion. The outer peripheral surface of the roller cylinder 2 is uniformly generated with the heating rod-shaped heaters 12 at both ends as the heating rod-shaped heaters toward the inner peripheral surface side of the roller cylinder 2 of the heating roller 1 in the circumferential direction of the roller cylinder 2. They are arranged alternately and evenly.

全長にわたって発熱する複数本の全部発熱棒状ヒータ１１は、従来からこの種の加熱ローラに用いられていた所謂棒状ヒータであるが、両側端部発熱棒状ヒータ１２は、本発明に基づくもので、従来の棒状ヒータの全長の一部の長さ領域のみを発熱部とした部分発熱棒状ヒータの一種であって、この実施例１に示す両側端部発熱棒状ヒータ１２は、棒状ヒータの中央部を除く両側端部のみが発熱する発熱部としたものである。以下、この発熱部を両端発熱部１２２という。 The plurality of all-heating rod-shaped heaters 11 that generate heat over the entire length are so-called rod-shaped heaters that have been conventionally used for this type of heating roller, but the heating rod-shaped heaters at both ends are based on the present invention and are conventionally used.

As shown in the figure, they are evenly arranged on the inner peripheral surface side of the roller cylinder.

ここで、「交互に組合せて均等に」とは、加熱ローラの外周面の温度均一性の確保に資する方向での各棒状ヒータの配設を意味する。
従って、各棒状ヒータの数や周方向での配置間隔は図示の実施例に限定されない。
尚、各棒状ヒータは図１に示すように加熱ローラ軸３に設けられ支持部材４で保持される。 Here, "alternately combined and evenly" means the arrangement of the rod-shaped heaters in a direction that contributes to ensuring the temperature uniformity of the outer peripheral surface of the heating roller.
Therefore, the number of rod-shaped heaters and the arrangement interval in the circumferential direction are not limited to the illustrated embodiment.
As shown in FIG. 1, each rod-shaped heater is provided on the heating roller shaft 3 and is held by the support member 4.

この実施例１の加熱ローラ１によれば、全長にわたって発熱する複数本の全部発熱棒状ヒータ１１に通電させる従来と同様の通電回路、即ち、本発明でいう全部通電制御回路(図示せず)に加えて、中央部を除く両側端部のみが発熱する複数本の両側端部発熱棒状ヒータ１２に通電させる両端部通電制御回路(図示せず)を設けて、この両端部通電制御回路を加熱ローラ１のローラ筒２の中央部側の温度に応じて通電制御するだけで、或いは又、この両端部通電制御回路と前記の全部通電制御回路との２回路を通電制御することによって、加熱ローラ１の両端部側の温度を前記中央部側の温度と同等温度に容易に制御することができ、従来の連続昇華転写用加熱ローラに較べて、加熱ローラのローラ筒外周面におけるローラ中央側とローラ両端側との温度均一性を比較的容易に実現させることができ、連続昇華転写機による転写の品質をより一層向上させることができる。 According to the heating roller 1 of the first embodiment, the conventional energization circuit for energizing a plurality of all-heating rod-shaped heaters 11 that generate heat over the entire length, that is, the all-energization control circuit (not shown) according to the present invention. In addition, an energization control circuit (not shown) at both ends is provided to energize a plurality of heating rod-shaped heaters at both ends where only the end portions on both sides excluding the central portion generate heat, and the energization control circuit at both ends is heated by a roller. The heating roller 1 can be energized only by controlling the energization according to the temperature on the central portion side of the roller cylinder 2 of 1, or by energizing and controlling the two circuits of the energization control circuit at both ends and the above-mentioned all energization control circuit. The temperature on both ends of the heating roller can be easily controlled to the same temperature as the temperature on the central portion side, and the roller center side and the roller on the outer peripheral surface of the roller cylinder of the heating roller are compared with the conventional heating roller for continuous sublimation transfer. Temperature uniformity with both ends can be achieved relatively easily, and the quality of transfer by the continuous sublimation transfer machine can be further improved.
