  The present invention relates to an air conditioning system for preventing dew condensation from occurring inside a printing apparatus when printing a printing material.

  In general, a rotary press is known as a printing apparatus used for offset printing on a substrate. Conventional rotary presses generally include a printing apparatus main body for printing on a printing material and an electric motor panel for driving the printing apparatus main body, and the dampening water of the printing plate provided on the outer peripheral surface of the plate cylinder adheres to it. The ink is prevented from adhering to the non-image area, and the ink is adhered to the image area where no dampening solution is adhered, and the ink is transferred to the blanket cylinder so that printing is performed on the substrate. It is configured.

  In this type of conventional printing device, the dampening water evaporated from the printing plate increases the relative humidity in the printing device during printing, and the humid air is cooled by metal members such as finger guards and blanket washers. It is easy for condensation to occur. And when this condensed water is dripped on the outer peripheral surface of the plate cylinder or the blanket cylinder, there is a possibility that the printing process will be adversely affected, resulting in loss of paper and a decrease in productivity.

  Therefore, conventionally, in order to prevent such condensation from occurring in the printing apparatus, it has been proposed to arrange a blower outside the printing apparatus and to blow the air from the blower into the printing apparatus by piping. (For example, refer to Patent Document 1).

  In the printing apparatus 10, first, the printing material is supplied from the paper feeding apparatus 12 to the first printing apparatus main body 13 at the lowest stage. In the left side printing units 23L, 24L, 25L, and 26L and the right side printing units 23R, 24R, 25R, and 26R of the first printing apparatus main body 13, the printing plate of the plate cylinder 27 is formed via the roller row 28a of the fountain solution device 28. A dampening solution is supplied, and this dampening solution adheres only to the hydrophilic non-image area of the printing plate.

  At this time, ink of a predetermined color (for example, black) is supplied to the printing plate of the plate cylinder 27 via the roller row 29 a of the ink supply treatment 29. Since this ink is oily, it is repelled in the non-image area of the printing plate to which dampening water is adhered, and adheres only to the oleophilic image area.

  Next, the ink of a predetermined color attached to the image line portion is transferred to the outer peripheral surface of the blanket cylinder 30 and then transferred to both sides of the substrate to be supplied supplied between the left and right blanket cylinders 30 and printed. The

  Subsequently, in the printing units 24L, 24R, 25L, 25R, 26L, and 26R of the second to fourth printing apparatus main bodies 14, 15, and 16 in the upper stage, a predetermined color ( For example, an image line of cyan, magenta, and yellow) is printed, and a printed material on which image lines of predetermined colors are printed is discharged from the paper discharge device 17.

As described above, while the image is printed on the printing material by the printing apparatus 10, a predetermined air volume (for example, 26 ° C. DB, 50% RH) adjusted to a predetermined temperature and humidity by the motor board air conditioner 64 (for example, 1,700 m ³ / h) of air SA. The air SA passes through the main air supply duct 66 and the first to fourth branch air supply ducts 67, 68, 69, 70 of the air guide facility 65, and the first to fourth motor boards 36, 37, 38, The first to fourth electric motor panels 36, 37, 38, 39 are cooled respectively.

The air SA1 of a predetermined air volume (for example, 450 m ³ / h) supplied from the motor board air conditioner 64 to the first motor board 36 cools the first motor board 36 and is mixed with the internal air. The temperature increases and the relative humidity decreases (actually 30.4 to 31.7 ° C. DB, 33.0 to 34.0% RH), and air with a predetermined air volume (for example, 400 m ³ / h) As the heat exhaust HA1, the first thermal exhaust supply fan 75 of the first printing main body supply facility 71 is driven to pass through the first thermal exhaust supply duct 74 from the first outlet 76 into the lower maintenance space 34. The inside of the first printing apparatus main body 13 is mainly heated.

The air SA2 having a predetermined air volume (for example, 450 m ³ / h) supplied from the motor board air conditioner 64 to the second motor board 37 cools the second motor board 37 and is mixed with the internal air. As a result, the temperature increased and the relative humidity decreased (measured to be 31.2 to 32.8 ° C. DB, 31.0 to 32.0% RH), and a predetermined air flow (for example, 400 m ³ / h) The second air exhaust supply duct 77 is driven by the second heat exhaust supply fan 78 of the second printing main body supply facility 72 as the air exhaust HA2 and the second maintenance outlet space 79 is passed through the second outlet 79. The inside of the second printing apparatus main body 14 and the third printing apparatus main body 15 is mainly heated.

Further, the air SA3 of a predetermined air volume (for example, 400 m ³ / h) supplied from the motor panel air conditioner 64 to the third motor panel 38 cools the third motor panel 38 and is mixed with the internal air. As a result, the temperature increases and the relative humidity decreases (actually measured to be 31.7 to 32.0 ° C. DB, 32.0 to 35.0% RH), and a predetermined air volume (for example, 180 m ³ / h) Of the third air through the third heat exhaust supply duct 80 by the third heat exhaust supply fan 81 of the third printing main body supply facility 73 as the heat exhaust HA3. Are blown toward the space 82 on the side of the left and right printing units 25L, 25R, 26L, and 26R of the printing apparatus main bodies 15 and 16. As a result, the thermal exhaust HA3 forms an air flow that heats the surfaces of the non-heating portions such as the blanket washer 31 and the finger guard 32, and mainly heats the interiors of the third and fourth printing apparatus main bodies 15 and 16.

  After that, the heat exhaust that is blown out from the first to third outlets 76, 79, and 83 into the first to fourth printing apparatus bodies 13, 14, 15, and 16 to heat the apparatus body. HA 1, HA 2, and HA 3 are discharged from the air collection ports 84 through the exhaust duct 85 to the outside of the room in which the printing apparatus is installed by driving the exhaust fan 86.

  By the way, as described above, while the image is printed on the printing material in the printing apparatus 10, a part of the dampening water supplied by the dampening water apparatus 28 evaporates, and the first to fourth printing apparatus main bodies 13 are evaporated. , 14, 15 and 16 have a higher relative humidity. Therefore, when the interiors of the first to fourth printing apparatus main bodies 13, 14, 15, 16 are not heated by the hot exhausts HA1, HA2, HA3, the blanket washer 31, finger guard 32, etc., which are non-heating parts The temperature difference between the metal surface temperature and the dew point temperature of the air inside the device is almost zero (actual measurement: 0.0 to 0.6 ° C). Condensation may occur on the metal surface, and condensation water may drop. is there.

  On the other hand, when the inside of the first to fourth printing apparatus main bodies 13, 14, 15, 16 is heated by the hot exhausts HA1, HA2, HA3 as in the present embodiment described above, The relative humidity in the fourth printing apparatus main body 13, 14, 15, 16 decreases due to mixing with the heat exhaust HA1, HA2, HA3, and the metal surface temperature of the blanket washer 31, finger guard 32, etc., which are non-heat generating parts. Is sufficiently higher than the dew point temperature of the air inside the apparatus (in actual measurement, 1.2 to 2.9 ° C.), and the occurrence of dew condensation on the metal surface and the dew condensation water on the plate cylinder 27 and the blanket cylinder 30 It can prevent reliably dripping on an outer peripheral surface. Therefore, in the printing process by the printing apparatus 10, it is possible to prevent the generation of damaged paper and increase the yield. Further, by preventing the occurrence of waste paper, it is not necessary to perform an operation of removing the waste paper during the printing process, so that the efficiency of the printing work can be improved.

  Further, according to the air conditioning system 50 of the printing apparatus 10 according to the above-described embodiment, the air blown into the apparatus from the first to third outlets 76, 79, and 83 is generated in the non-heat generating portion inside the printing apparatus. Since a certain blanket washer 31, finger guard 32, etc. can be efficiently heated and discharged to the outside, it is possible to reliably prevent the formation of dew condensation inside the apparatus and to ensure that the interior of the room where the printing apparatus is installed. The environment can be kept good.

Further, the heat exhausts HA1, HA2, HA3 from the first to third electric motor panels 36, 37, 38 are reused for heating inside the first to fourth printing apparatus main bodies 13, 14, 15, 16. Thus, the exhaust amount from the entire printing apparatus 10 can be reduced. For example, in the above-described embodiment, the ratio of the heat exhausts HA1, HA2, HA3 to the air volume SA supplied from the motor board air conditioner 64 per one tower unit 18 is as follows:
(400 m ³ / h + 400 m ³ / h + 180 m ³ / h) ÷ 1,700 m ³ /h≈0.58
It becomes. That is, about 58% of exhaust gas can be reused, so that energy saving can be achieved.

  Furthermore, since the first to fourth motor boards 36, 37, 38, 39 can be cooled by clean air from the motor board air conditioner 64, dust in the air is an electrical component in the motor board. Can be prevented, and the durability of the first to fourth electric motor boards 36, 37, 38, 39 can be improved.

  In the above-described embodiment, the printing units 23L, 23R, 24L, 24R, 25L, 25R, 26L, and 26R are arranged to face each other on both the left and right sides so that image lines can be printed on both sides of the substrate. However, the printing cylinders 23 of the printing units 23L, 23R, 24L, 24R, 25L, 25R, 26L, and 26R, the dampening water supply device 28, the ink supply device 29, and the like are disposed only on either the left or right side. You may comprise so that an image line can be printed only on the single side | surface of printed matter.

  Further, in the above-described embodiment, the left and right printing units 23L, 23R, 24L, 24R, 25L, 25R, 26L, and 26R of the first to fourth printing apparatus bodies 13, 14, 15, and 16 are dampened. Although the water supply device 28 and the ink supply device 29 are alternately arranged above and below the plate cylinder 27, all the printing units 23L, 23R, 24L, 24R, 25L, 25R, 26L, and 26R are dampened. The water supply device 28 and the ink supply device 29 may be disposed below the plate cylinder 27.
