どの副成物が発生し作業環境を悪化させるとか、蒸発し
た溶剤による爆発などの危険がある等の問題もあった。However, in such drying equipment, drying is performed by blowing hot air, so there is a problem that heating efficiency is poor (it requires a long drying path length, resulting in a large drying equipment). There was also the problem that it took time to raise the temperature to a predetermined temperature.Furthermore,
Since gas is combusted to create hot air, there are problems such as by-products such as carbon oxide are generated, deteriorating the working environment, and there is a risk of explosion due to evaporated solvent.
本発明はかかる従来技術の問題点に鑑みてなされたもの
で、コンパクトでクリーンな、エネルギー効率の良い、
しかも敏速に立ち上げることの可能な乾燥装置を提供す
ることを目的とする。The present invention has been made in view of the problems of the prior art, and is a compact, clean, and energy efficient system.
Moreover, it is an object of the present invention to provide a drying device that can be started up quickly.

本発明に使用する熱源としては、ハロゲンランプ。The heat source used in the present invention is a halogen lamp.
キセノンランプ等のランプ、ニクロム線等の電熱線。Lamps such as xenon lamps, heating wires such as nichrome wires.
遠赤外線を出すセラミック等任意であるが、高熱量を放
射しうるハロゲンランプが好ましい。Any lamp can be used, such as a ceramic lamp that emits far infrared rays, but a halogen lamp that can emit a high amount of heat is preferred.

An exhaust system 8 is connected to exhaust the solvent generated from the exhaust system. As shown enlarged in FIG. 2, the heater 7 includes a halogen lamp 10 constituting a linear heat source, and a condensing lamp with an elliptical cross section that reflects electromagnetic waves from the halogen lamp 10 and condenses it onto the web 1. It has a mirror 11.
ここで、電磁波を集光ミラー１１によってウェブ１上に
集光させる程度としては、必ずしも厳密に一点に集光さ
せる必要はなく、成る程度の幅内に集光させればよい。Here, the extent to which the electromagnetic waves are focused onto the web 1 by the focusing mirror 11 does not necessarily need to be strictly focused on one point, but may be focused within a certain width.

The present invention is not limited to this, and may be configured to use both radiant heating by the heater 7 and conventional heating by hot air. That is, a hot air blowing nozzle is arranged between the heaters 7,
Heating by the heater 7 and heating by the hot air blowing nozzle can also be performed in parallel. In this case as well, rapid heating can be performed by the heater 7, so the amount of hot air used can be reduced compared to the conventional drying apparatus that uses only hot air heating, and the bath length of the web can be shortened. It is preferable to use hot air blowing in combination in this way because it can accelerate the evaporation of the ink solvent.

ともできる。Although the above embodiment shows a drying device installed in a four-color offset rotary press, the drying device of the present invention is not limited to this printing press.
It can be used for drying ink in various types of printing presses. For example, conventionally, non-heat-type one-color or two-color offset rotary presses with a simple structure have been used to print on paper that can be permeated and dried. 1 downstream of the printing section
By providing the heater 7 so as to face the web, a compact drying device can be formed and the ink can be dried. Therefore, it is possible to print on paper that cannot be permeated and dried, such as coated paper, and the applications of the three-wheel press are expanded. Furthermore, the present invention can be used not only for drying ink in a printing press, but also for drying a coating material applied to a web in a coating device.

取付けることができる等種々な効果を有している。As explained above, the drying apparatus of the present invention is configured to condense electromagnetic waves from a line-shaped heat source with a condensing mirror and irradiate the web to be dried. This makes it possible to effectively utilize energy and apply high energy locally, making it possible to heat the web with high efficiency, shorten the path length of the web required for drying, and make it possible to have a compact structure. Furthermore, when starting up the device, only the heat source needs to be in a state where it can radiate a predetermined amount of electromagnetic waves, so it is possible to start up the device in an extremely short time compared to conventional hot air type devices. Furthermore, since there is no need to create hot air, the structure can be clean and compact, and it has various effects such as being able to be easily installed in existing printing machines.
