するものである。 The purpose of this invention is to easily maintain and inspect the hysteresis doctor, which is an important part of the ink supply system.In an arch-type rotary printing press equipped with a hysteresis elimination type inking device, the doctor roller is placed above the plate cylinder. The present invention provides a rotary printing press in which a roller is placed between the doctor roller and the plate cylinder, the hysteresis surface of the doctor roller is brought to the outside of the arch, and the hysteresis doctor is placed outside the arch. That is.

が上下逆である。 An embodiment of the present invention will be described below with reference to the drawings. Fig. 2 shows a first embodiment of the rotary printing press of the present invention, and the ink supply system is a keyless inking system. Note that the arrangement of the rollers in FIG. 2 is upside down compared to FIG. 1.

いる。 In FIG. 2, a frame 11 rotatably supports a blanket cylinder 01, a plate cylinder 02, a forming roller 03, a doctor roller 04, a delivery roller 05, and an ink source roller 06. The ink source roller 06 has a delivery roller 05, a delivery roller 0
5, the doctor roller 04 is attached to the doctor roller 04, the forming roller 03 is attached to the forming roller 03, and the plate cylinder 02 is attached to the forming roller 03.
However, the blanket cylinder 01 is in contact with the plate cylinder 02.

にある。 Further, a history doctor 09 is in contact with the doctor roller 04 through an ink film. Ink source roller 06
A supply doctor 10 is arranged parallel to the axis with a uniform gap. Note that the arrows indicate the rotation direction of the cylinder and rollers. Further, the ink reservoir 07 is located almost vertically below the history doctor 09 and the supply doctor 10.
次に作用を説明すると、インキ供給側の反対

達される。 Next, the operation will be described. On the side opposite to the ink supply side, that is, on the history side, unconsumed ink history doctor 09 uniformly scrapes off the ink that has not been consumed. The ink in the ink reservoir 07 is supplied to the ink source roller 06 by a pump (not shown), and is transferred to the delivery roller by the supply doctor 10 so as to have a uniform film thickness in the width direction of the roller.

残らないようにできる。 Furthermore, the ink is transferred to the doctor roller 04 and the formation roller 0.
3. The image is transferred to the plate cylinder 02, the blanket cylinder 01, and transferred to the sheet 08. Since ink is not transferred to the non-image area of the plate cylinder 02, the formation roller 0
3. Unconsumed ink returns to the history side of the doctor roller 04. This ink is history doctor 09
This prevents any history from remaining on the supply surface of the roller.

９がアーチ外に出てくる。 In addition, the doctor roller 04 is moved from the cylinder plate 02 to the paper 08.
By arranging the doctor roller 04 in the flow direction, the hysteresis surface of the doctor roller 04 is placed outside the arch of the frame 11.
You can also come to Therefore history doctor 0
9 comes out of the arch.
以上詳細に説明した如く本考案は、ドクタロー

て容易になる。 As explained in detail above, in this invention, the hysteresis surface of the doctor roller is placed outside the arch, and the hysteresis doctor, which is the most important part requiring maintenance and inspection, is placed outside the arch, which saves space and improves workability. There is no need to enter the arch, which is difficult to enter, and workability and efficiency are greatly improved, and maintenance and inspection become extremely easy.
