４、[Prior Art] In offset printing machines and gravure printing machines, the ink application range is wide, for example from 300 mm or less to 3000 mm. -M, the ultraviolet radiators are arranged transversely to the paper transport direction. Further, it is possible to use one large reflector or to use a plurality of reflectors arranged side by side so that they do not overlap. And operating costs are the same regardless of paper width. [Problems to be Solved by the Invention] However, if the length exceeds a certain length, the irradiator will droop or become sagging. In extreme cases, it may hit the holding grip of the paper it is trying to pass through. Furthermore, for economic and physical reasons, only mercury vapor radiators have been used so far, and the polymerization of UV-curable inks and lacquers is carried out only in the spectral lines of mercury. Therefore, if the ink absorbs other wavelengths, the delivery ratio must be associated with longer or shorter crosslinking times. The object of the present invention is to overcome these various drawbacks in conventional devices. [Means for Solving the Problems 1] In order to achieve the above object, the ultraviolet drying device according to the present invention is particularly for finishing offset printing machines and gravure printing machines, and is composed of a plurality of small radiators. It is characterized by The radiators are preferably arranged end-to-end on a plurality of lines, and can be arranged so as to be staggered from those on other adjacent lines. Further, the arc length of the radiator is preferably 200 mm at maximum. Furthermore, the radiators can be of different types in the same unit. Embodiments Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an embodiment of the ultraviolet dryer according to the present invention. In this apparatus, a conveyor belt is arranged on a housing 1, and a product coated with ink or lacquer is conveyed on this conveyor belt, and the applied ink or lacquer is polymerized during conveyance. In the figure, 6 is a radiator, and a plurality of radiators 6 are arranged along an arrangement line, for example, four lines 2 to 5, and each line 2 to 5 is arranged along an arrangement line.
5, adjacent radiators 6 are arranged end to end. And to get a uniform radiation area,
The radiators 6 of each line are arranged such that the positions of the radiators 6 of the adjacent lines are shifted from each other in the direction perpendicular to the lines 2 to 5. These small radiators 6 are those that operate at a voltage of 380V or less. This working voltage is the maximum safe value when applied to the dryer or electrical cabinet without interrupting the power supply to the printing press. On the other hand, safety-related work is outside the scope of legislation. And the work can be done by ordinary electricians. Because of this low voltage, conventional electrical wiring systems can be employed, rather than requiring the use of high voltage electrical engineers as with conventional devices. Further, the arc length of the radiator 6 is preferably 200 mm at maximum. This is because the current becomes unstable if this limit is exceeded. And with such a short length, the radiators will not overlap. In addition, according to the illustrated embodiment, if the material to be conveyed is narrow, it can be divided into blocks in the horizontal direction. Furthermore, to reduce the crosslinking time, Different metal iodides can be used, for example iron/cobalt, gallium/lead, thallium, which of course may not be mentioned here, but which harmonize well with the spectrum of the ink or lacquer. If the ultraviolet ray drying device according to the present invention is made of a plurality of small radiators, the efficiency can be increased with only a small cost. This has the effect of making it possible for the radiator to sag in the middle and eliminate contact with the holding grip of the paper that is about to pass through.Also, the radiator can be placed on multiple lines so that the ends touch each other. By arranging them side by side and shifting their positions from those on other adjacent lines, it is possible to obtain a uniform radiation area.Furthermore, the length of the arc of the radiator can be increased to a maximum of 200 mm. This has the effect of making it possible to stabilize the supplied current.Also, by using various types of radiators in the same unit, it is possible to make the ink or lacquer absorb other wavelengths. , which has the effect of making it possible to reduce crosslinking time. 4.
