本発明は、印刷物を熱風によつて連続して乾燥
させる装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for continuously drying printed matter with hot air.
従来のこの種の装置は、乾燥室に印刷物が通過
する入口と出口を設け、乾燥室内を走行する印刷
物を乾燥させた熱風を加熱して再び印刷物の乾燥
に用いる熱風循環路を設け、熱風循環路の熱風の
一部を浄化して大気に放出する浄化路を設けてい
る。ところが、乾燥室の出口から印刷物と共に有
害な臭気即ち印刷インキの溶剤蒸気が漏れ出る。
そこで、有害な臭気の漏出を防止するため、浄化
路から大気に放出する浄化熱風の量を増大させ、
乾燥室の負圧を大きくして、乾燥室にその入口と
出口から吸入される新鮮空気の量を増大させてい
る。ところが、このようにして臭気の漏出量を減
少させると、新鮮空気の吸入量の増大により新鮮
空気を加熱する熱量が増大し、また、浄化熱風の
放出量の増大により大気に放出される熱量が増大
すると共に熱風の浄化量が増大する。即ち、エネ
ルギ消費量が著しく増大する。 Conventional devices of this kind have a drying chamber with an inlet and an outlet through which the printed matter passes, and a hot air circulation path that heats the hot air that dries the printed matter traveling inside the drying chamber and uses it again to dry the printed matter. A purification channel is installed to purify a portion of the hot air and release it into the atmosphere. However, a harmful odor, ie, printing ink solvent vapor, leaks out from the outlet of the drying chamber together with the printed matter.
Therefore, in order to prevent the leakage of harmful odors, we increased the amount of purified hot air released into the atmosphere from the purification path.
The negative pressure in the drying chamber is increased to increase the amount of fresh air drawn into the drying chamber through its inlet and outlet. However, when the amount of odor leakage is reduced in this way, the amount of heat to heat the fresh air increases due to the increase in the amount of fresh air intake, and the amount of heat released to the atmosphere increases due to the increase in the amount of purified hot air released. As the temperature increases, the amount of hot air purification increases. That is, energy consumption increases significantly.
そこで、上記のような従来装置の欠点を除去す
るため、特開昭55−148163号公報に開示されてい
るように、浄化路の浄化熱風の一部を乾燥室の入
口と出口にそれぞれ導き、入口と出口において、
それぞれ、浄化熱風を印刷物の両面にほぼ直角に
吹き付けて熱風幕を形成する装置が発明された。 Therefore, in order to eliminate the drawbacks of the conventional apparatus as described above, as disclosed in Japanese Patent Application Laid-Open No. 55-148163, a part of the purified hot air in the purification channel is guided to the inlet and outlet of the drying chamber, respectively. At the entrance and exit,
In each case, a device was invented that blows purified hot air onto both sides of a printed material at approximately right angles to form a hot air curtain.
ところが、乾燥室の出口から印刷物に連れて流
出する臭気を、印刷物にほぼ直角に吹き付ける熱
風幕によつて十分に遮断することは困難であり、
臭気の漏出を十分に防止することができない。 However, it is difficult to sufficiently block out the odor that flows out from the drying chamber outlet along with the printed matter by using a hot air curtain that blows almost perpendicularly to the printed matter.
It is not possible to sufficiently prevent odor leakage.
本発明の目的は、上記のような従来の課題を解
決することである。 An object of the present invention is to solve the conventional problems as described above.

とを特徴とする印刷物の熱風連続乾燥装置であ
る。 The present invention provides a drying chamber with an inlet and an outlet for printed matter, and a hot air circulation path that heats the hot air that dries the printed matter traveling in the drying chamber and uses it again to dry the printed matter, and a portion of the hot air in the hot air circulation path. In a hot-air continuous drying device for printed matter, which is equipped with a purification path that purifies the air and releases it into the atmosphere, a purified high-temperature air chamber is connected to the inlet and outlet of the drying chamber via a flat passage, and the printed matter is transported to the purified high-temperature air chamber. , a flat passageway, an inlet, a drying chamber, an outlet, a flat passageway, and a purified high-temperature air chamber, each of which is provided with a purified high-temperature air passage that supplies part of the purified hot air from the purification passage to both purified high-temperature air chambers. This continuous hot air drying apparatus for printed matter is characterized in that the purified hot air supplied to the purified high-temperature air chamber flows into the drying chamber from the inlet and outlet through flat passages, respectively.
この熱風連続乾燥装置においては、印刷物が浄
化高温空気室、扁平通路、入口、乾燥室、出口、
扁平通路と浄化高温空気室を順次通過し、乾燥室
の入口側と浄化高温空気室に供給された浄化熱風
が扁平通路を経て入口から乾燥室に流入すると共
に、乾燥室の出口側の浄化高温空気室に供給され
た浄化熱風が扁平通路を経て出口から乾燥室に流
入する。 In this hot air continuous drying device, the printed matter goes through a purified high-temperature air chamber, a flat passage, an inlet, a drying chamber, an outlet,
The purified hot air passes through the flat passage and the purified high-temperature air chamber in sequence, and is supplied to the inlet side of the drying chamber and the purified high-temperature air chamber. The purified hot air supplied to the air chamber flows into the drying chamber from the outlet through the flat passage.
従つて、両浄化高温空気室に供給された浄化熱
風が乾燥室に入口と出口から流入するので、乾燥
室に入口と出口から吸入される新鮮空気の量が少
なく、浄化路から大気に放出される浄化熱風の量
が少なくて、エネルギ消費量が少ない。 Therefore, since the purified hot air supplied to both purified high-temperature air chambers flows into the drying chamber from the inlet and outlet, the amount of fresh air taken into the drying chamber from the inlet and outlet is small, and the amount of fresh air is not released into the atmosphere from the purifying path. Since the amount of purifying hot air is small, energy consumption is low.
また、乾燥室の出口側の扁平通路においては、
印刷物が乾燥室側から浄化高温空気室側へ走行す
ると共に、浄化熱風が浄化高温空気室側から乾燥
室側へと流動し、扁平通路中を浄化熱風が印刷物

平通路中を印刷物に連れて流動する臭気は、印刷
物と反対方向に流動する浄化熱風によつて印刷物
から剥離されて乾燥室側へ戻され、印刷物と一緒
に浄化高温空気室から外部に流出しない。 In addition, in the flat passage on the exit side of the drying chamber,
As the printed matter travels from the drying chamber side to the purified high-temperature air chamber side, the purified hot air flows from the purified high-temperature air chamber side to the drying chamber side, and the purified hot air flows in the opposite direction of the printed matter in the flat passage, so that the drying process is completed. The odor that flows along with the printed matter in the flat passage on the exit side of the chamber is separated from the printed matter by the purified hot air flowing in the opposite direction to the printed matter and returned to the drying chamber, where it is returned to the purified high-temperature air chamber together with the printed matter. Do not leak to the outside.
従つて、熱風幕を印刷物にほぼ直角に吹き付け
る従来装置に比較して、臭気の漏出が十分に防止
される。 Therefore, leakage of odors is more effectively prevented than in conventional devices in which a hot air curtain is blown approximately perpendicularly to the printed matter.

２２を経て各浄化高温空気室２０に供給される。 In the hot air continuous drying device for printed matter in this example,
A strip of printed matter P sent out from a printing machine (not shown) is passed through a flat passage 21, a purified high-temperature air chamber 20, and a flat passage 2.
1, inlet 2, drying chamber 1, outlet 3, flat passage 21,
The air passes through the purified high-temperature air chamber 20 and the flat passage 21 in sequence. On the other hand, hot air circulates in the hot air circulation path. In the drying chamber 1, the strip-shaped printed material P is continuously dried by hot air. In the purification channel, a portion of the hot air containing printing ink solvent vapor in the hot air circulation channel is purified by oxidation. The purified hot air is discharged to the atmosphere, while being supplied to each purified high temperature air chamber 20 via each purified high temperature air path 22.
