【発明の詳細な説明】 本発明は紫外線照射装置の改良Ｃ′−関する。[Detailed description of the invention] The present invention relates to an improved ultraviolet irradiation device C'-.
近年光硬化性インクを使用した印刷物を乾燥させるため
に紫外線照射装置が使用されている。そ−して、紫外線
源としてはたとえば高圧水銀ランプなどの紫外線ランプ
が使用されている。ところが。In recent years, ultraviolet irradiation devices have been used to dry printed matter using photocurable ink. For example, an ultraviolet lamp such as a high-pressure mercury lamp is used as the ultraviolet source. However.
このような紫外線ランプは紫外線とともに大量の熱線を
放射するため印刷物が熱損するおそれがあるＯ
これ４＝対し、たとえば特開昭５３−１１３１７９号に
見られるように、紫外線ランプの下方に石英ガラスから
なる管形フィルタを設け、このフィルタ内に水または空
気を通流して冷却する紫外線照射装置か知られている。Such ultraviolet lamps emit a large amount of heat rays along with ultraviolet rays, which may cause heat loss to printed materials.On the other hand, as seen in Japanese Patent Application Laid-open No. 53-113179, for example, quartz glass is placed below the ultraviolet lamp. An ultraviolet irradiation device is known in which a tubular filter is provided and water or air is passed through the filter for cooling.
このものは紫外線に伴ってランプから放射された熱線を
フィルタで除却するので、印刷物な熱損から保護する効
果がある。しかしその反曲、室内の自然気流などの理由
によって印刷物が浮き上がる欠点がある。This filter filters out the heat rays emitted from the lamp along with the ultraviolet rays, so it has the effect of protecting printed matter from heat loss. However, it has the disadvantage that the printed material may float due to the bending, natural airflow in the room, etc.
また、器具の両側から印刷物に冷却風を吹きつけて印刷

ａ＆二取り付けられないおそれがあり、また、冷却風の
風量や風速の―節が難しく、風量や風速が不足すれば浮
き上り防止の効果がなく、反対に風量が多ければランプ
が過冷却されて点灯が不安定になる。There is also a known device that blows cooling air onto the printed material from both sides of the device to cool the printed material and prevent it from lifting up. However, with this device, the external size of the device becomes large and there is a risk that it may not be possible to attach the printing a & 2. Also, it is difficult to control the volume and speed of the cooling air, and if the volume and speed of the cooling air are insufficient, it will not be effective in preventing floating. If there is a large amount of airflow, the lamp will become overcooled and the lighting will become unstable.

止するものである。The present invention has been made in order to eliminate the drawbacks of the prior art, and consists of an ultraviolet-transparent blower tube (with two downward nozzles) installed in front of the ultraviolet lamp, and a cooling gas flowing through the blower tube. By jetting forward from a nozzle installed in the blast pipe, the jet stream prevents the irradiated surface from lifting up.
以下、本発明の畦細を図示の実施例によって説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The ridges of the present invention will be explained below with reference to illustrated embodiments.

The irradiated surface is inserted directly below the irradiated surface. The above air pipe (5)
is made of, for example, a transparent quartz tube, from one end to the other end wg
! Cooling gas such as air, nitrogen, and carbon dioxide flows through the tube, and a part of this cooling gas is branched off and injected forward from the nozzle (6). The irradiation direction (6) is a thin piece of paper or the like,
The surface is coated with original curable ink, JJT, or curable paint.

るので紫外線の大部分を透過し、に＆、線を吸収する。Next, the effect will be explained. Turn on the ultraviolet lamp (1),
Cooling gas is passed through the blast pipe (5), and the object to be illuminated (6) is placed in a fixed position directly below the lamp (1). Then, the cooling gas is jetted forward from the nozzle (6) and does not reach the irradiated surface (7). In addition, ultraviolet rays and heat rays from the lamp (11) are emitted in the direct downward direction (12), blowing air (5).
Since the blast pipe (5) is made of quartz glass, it transmits most of the ultraviolet rays and absorbs the ultraviolet rays.

れもない。Sent for this reason! 1° (51) is heated, or this heat is removed by the cooling gas. Then, the removed ultraviolet edge of the hot rays is directed further downward from the blast pipe (5) and enters the irradiation direction (7), and! In this way, the irradiated ultraviolet rays do not contain much heat rays, so the irradiated surface (7) is not overheated, and therefore the irradiated surface (7) ) has the additional effect of preventing heat loss.Furthermore, since the fumarole cools the irradiated object (1), for this reason as well, heat loss in the irradiated direction (7) can be prevented.In addition, the exhaust hole (314 m Since the lamp (11) is cooled by the ventilation, there is no risk of the maple performance decreasing due to overheating.

、くなる。Next, a second embodiment is shown in FIG. This one has a blow pipe α9 configured as a horizontally long flat body, and a large number of nozzles such as uti, ae-, etc. are installed on the front surface of the air pipe α9, and other parts are not given the same reference numerals. I will omit the explanation. Since this item blows airflow over a wide area in the irradiation direction, it is possible to press the irradiation area even more strongly. If the size of the filter is sufficiently large and the structure and material have heat ray blocking properties, the filter effect will be even greater.

! The air pipes □□□, - are installed horizontally in parallel.
. . 6 two forward-facing nozzles (2), (e), etc. are provided, and the other facing portions are given the same reference numerals and explanations will be omitted. This also blows the airflow over a wide area in the irradiation direction, so the irradiation direction can be pressed down even more strongly. Then, connect the air pipe (c), □□□... to the lamp (
If the filters are arranged sufficiently densely so as to block the front of the filter 11, and if the constituent material thereof has heat ray blocking properties, the filter effect will be greatly increased.

端から他端に貫流してもよい。Incidentally, the ultraviolet lamp may be a metal illite lamp. Furthermore, the material for constructing the air pipe is quartz glass (not limited to any material that transmits ultraviolet rays; 'ii) The transmittance of light is not an issue, and the heat ray blocking properties are added as a filter effect. .A part of the airflow may flow through the air pipe from one end to the other end.
また、ノズルは前向きであれはその位置や数に限定はな

あってもよい。Further, as long as the nozzles face forward, there are no limitations on their position or number; for example, they may be slits that are continuous in the longitudinal direction of the blast pipe.

Since the cooling gas is injected downward from the filter 2, the filter blocks the heat rays emitted from the lamp, and the upward jet flow 62 prevents the object from lifting and cools the object. can do. Further, since the present invention allows the filter to also function as a ventilation pipe, it has the advantage of being able to be made compact.
