Fig. 9 is a side view of a conventional flexographic printing machine, and Fig. 10 is a perspective view of a main part thereof (refer to Japanese Patent Laid-Open Publication No. Hei 5-200986). The inking roller (1) and the press roller (2) are in contact with each other. Between the two rollers (1) and (2), a groove-shaped ink storage section (11) printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs will be formed. . Under the inking roller (1), the roller (1) is contacted, and is equipped with a plate trunk (9) equipped with a printing plate (90). Below the plate trunk (9), a receiving roller (9 1) is provided. ). The inking roller (1) is arranged so that the torso (9) can approach and leave. When the two rollers (1) and (2) are rotated backward in the direction of the twisted ink (inward rotation direction) of the ink reservoir (1 1), the ink on the surface of the inking roller (1) will be transferred to the plate installed on the plate. The printing plate (not shown) of the trunk (9) will be printed on the kraft paperboard S to be fed between the printing plate trunk (9) and the receiving cylinder (9 1). As shown in Fig. 10, in the ink storage section (1 1), a container (9 6) provided on the floor is supplied with a tube (9 4) through a pump (9 7).

If the lower end of the nozzle (4) is marginally separated from the lower end of the ink storage portion (1 1), the ink supply suction nozzle (4) may be kept immersed in the ink storage portion (1 1) and moved. . Where the diluent supply nozzles (7), (7), and (70) are supplied to the diluent, the viscosity of the ink will decrease. However, the ink flow generated by the ink suction in the two recovery sections of the ink supply suction nozzle (4) is to supplement the ink flow caused by the ink used for printing and reduce the viscosity of the ink and prevent the ink Uneven viscosity. In particular, according to the embodiment, the ink where the ink viscosity is temporarily reduced by the supply of the diluent from the diluent supply nozzle (7), (7) is recovered to the ink tank (3 1) by the ink supply suction nozzle (4). ), The effect of adjusting the viscosity of the ink in the ink tank (3 1) can be obtained. (Ink Recovery / Cleaning Liquid Recovery Mode) After the predetermined amount of printing has been completed, it is necessary to change the color of the ink for the next printing. At this time, wash the ink attached to the rollers (1), (2). Figure 4A to Figure 4C, the paper size of the waste paper used for ink recovery and cleaning liquid recovery mode is applicable to China National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) ▼ Printed and printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -21-523470 A7 B7_ V. Description of the invention (19) The operation of the liquid recovery nozzle (5). In order to replace the ink, the rotation of the rollers (1) and (2) will be stopped (please read the precautions on the back before filling this page), and the lifting drive device (3 2) will supply the ink to the suction nozzle (4) and The waste liquid recovery nozzle (5) is lowered to the lowered position of the ink storage portion 11 (Fig. 4A). The suction pipe (5 1) connected to the waste liquid recovery nozzle (5) is flexible and does not hinder the reduction of the waste liquid recovery nozzle (5). One side slides the closed tank (3), and the ink in the ink reservoir (1 1) is sucked by the ink supply suction nozzle (4) provided in the tank (3). At this time, the waste liquid recovery nozzle (5) will make it unattractive. As in the embodiment, when the ink is sucked by vacuum pressure, if the ink is supplied to the suction nozzle (4) through the length of the ink storage section (1 1) one or two times, the ink storage section can be almost sucked. (1 1) all the inks. Next, the ink supply suction nozzle (4) and the waste liquid recovery nozzle (5) are raised, and the drums (1), (2) are rotated, and the closed box (3) is slid while sliding in this state from the cleaning liquid supply nozzle (34) Disperse the washing liquid of water in the inking roller (1) for about 100 cc (Fig. 4B). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy Almost all the ink attached to the ink roller (1) in a thin film form is washed away, and the washing waste liquid will be stored in the ink storage section (1 1). A small amount of ink is attached to the inking roller (1) as a thin film, and because the ink is water-based, the amount of cleaning liquid required for washing is only a small amount. Stop the rotation of the rollers (1), (2), and lower the ink supply suction nozzle (4) and the waste liquid recovery nozzle (5) to the lowered position of the ink storage portion (1 1). The suction system of the ink supply suction nozzle (4) The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -22 · 523470 A7 B7 V. Description of the invention (20) Stop. In this state, the closed tank (3) is slid, and only the waste liquid recovery nozzle (5) is attracted, and the waste liquid is attracted to the recovery tank (50). (Please read the precautions on the back before filling in this page.) When the suction action of the recovery tank (50) is performed, the suction will also act on the discharge holes of the bank members (8) at both ends of the ink reservoir (1 1). The washing waste liquid will also be recovered from the bank member (8) to the recovery tank (50) (Figure 4C). As in the case of ink recovery, when the waste liquid recovery nozzle (5) is passed back and forth through the entire length of the ink storage section (1 1) once or twice, almost all of the cleaning liquid in the ink storage section (1 1) can be recovered. attract. After collection, the closed box (3) will stand by at the center of the ink storage section in the longitudinal direction. As mentioned above, when changing the ink, the ink can be recovered with almost no loss, and the amount of washing water required for drum cleaning is also small, and the concentration of the washing waste liquid is also low. Therefore, a large-scale facility for processing the waste liquid is not required, and the running cost for waste liquid processing can be suppressed. In order to change the color, the ink tank (3 1) in the closed box (3) is replaced. Then, the two nozzles (4), (5) are raised, and the rollers (1), (2) are rotated while attracting ink from the ink supply. The nozzle (4) is used to supply the ink printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of New Economy. At this time, the ink supply suction nozzle (4) is maintained in the standby position without moving it horizontally. Then, the recovery cylinder (50) is sucked in advance. As shown in FIG. 5A, the ink I flowing out of the nozzle (4) will flow toward the bank member (8) at the bottom of the ink storage portion (1 1). The bottom of the ink storage section (1 1) is stored with a waste liquid recovery nozzle (5). The paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) -23- 523470 A7 __ B7_ V. Description of the invention (21) A small amount of washing waste liquid collected after the completion. However, the ink I will flow to the bank member (8) side, and the residual waste liquid Η will be washed away by the ink I. (Please read the precautions on the back before filling in this page.) Due to the differences in the characteristics of ink I and the specific gravity and viscosity of the waste liquid and ink, the waste liquid Η will hardly mix with ink I and will be sent to the bank. The component (8) is flushed away. As shown in FIG. 5B, the ink I and the waste liquid pluton are also close to the bank member (8), and the liquid level will rise. Due to the attractive force of the recovery cylinder (50) in the discharge hole (8) of the bank member (8), the waste liquid pushed out of the discharge hole (8 1) of the bank member (8) will be recovered by the recovery tank (5 0) Attract. As mentioned above, the waste liquid will be flushed away to the bank member (8) side, the liquid level of the waste liquid will gradually increase, and the ink reservoir (1 1) side opening of the discharge hole (8 1) will be opened Closed with liquid level. As a result, air can be prevented from leaking from the discharge hole (81), and the waste liquid can be attracted with a strong suction force. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The machine just stopped the attraction of the recovery cylinder (50) just before the ink was discharged from the discharge hole (81) to the recovery cylinder (50). The timer measures the time before the ink supplied to the central part of the ink storage part (1 1) flows to the end of the ink storage part (1 1). The timer is set in advance or the waste is detected. A liquid quality detector having a difference in liquid quality between the liquid and the ink can be provided by being provided at an end portion of the ink storage portion (1 1) and the like. In fact, the waste liquid recovery will continue for about 40 seconds. As described above, the washing waste liquid can be recovered almost in its entirety. The wall surface of the ink storage section (1 1) is used as the waste liquid left behind by moistening, and the waste liquid that has not been recovered is a trace amount. Even if it is mixed with new ink, the color of the ink is also suitable for this paper. National Standard (CNS) A4 Specification (210 × 297 mm) -24- 523470 A7 B7 V. Invention Description (22) No effect. In this embodiment, two ink supply nozzles (4), (4 (please read the precautions on the reverse side and fill in this page)) are provided, and the ink is moved by being immersed in the ink in the two recovery intervals. Alternatively, the number of the ink supply suction nozzles (4) may be increased, and the ink supply suction nozzles (4) may be arranged along the long direction of the ink storage portion (1 1) to attract the ink without sliding the ink supply suction nozzles (4). However, the stirring effect of the ink is weak at this time. In this embodiment, the ink is supplied to the center portion of the ink storage portion (1 1), and is sucked to the end portion. Instead, the ink may be supplied at the end of the ink storage section (11) and sucked at the center. Furthermore, although in the above-mentioned embodiment, the press roller (2) is used as the press for pressing the ink on the inking roller (1), it is not limited to this. For example, as shown in FIG. 6, a band-shaped plate (2 2) may be pressed against the inking roller (1) over the entire length of the roller (1) to form an ink storage portion (1 1). ). In the case where the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed Figure 6, the strip plate (2 2) is in the direction opposite to the rotation direction of the inking roller (1) and supports the strip plate (2 2) (2 3) The wall surface constituting the ink storage portion (1 1), and the strip-shaped plate (2 2) is also the bottom of the ink storage portion (1 1). In the above embodiment, the supply and recovery of the ink to the ink storage unit (1 1) is performed by pressurizing and decompressing in the closed box (3), and the recovery of the washing waste liquid is performed by the recovery tank (5 0). However, it is also possible to use a vacuum pump for ink supply, recovery, and recovery of washing waste liquid. In the above embodiment, as shown in FIG. 5A and FIG. 5B, the ink I supplied to the ink storage section (1 1) pushes the residual waste liquid to the ink storage. ) A4 specification (210 × 297 mm) -25- 523470 A7 B7 V. Description of the invention (23) When the end of the product (1 1), the discharge hole (8 1) from the bank member (8) passes through the recovery pipe (5 2) The residual waste liquid is recovered. However, it is not limited to this, and the bank member (8) may be separated from the end faces of the drums (1), (2), and the waste liquid may be recovered by flowing away from the end of the ink storage portion (1 1). The present invention is not limited to water-based inks, and can also be applied to glycol-based inks having low viscosity and good drying speed.
